INTRODUCTION

Recently, the words "smart home", "intelligent building", "building automation" have become common in specialized literature, and sometimes in the media. At the same time, it often seems that the main thing in building automation is various spectacular “tricks”, such as turning on the light with a voice command or controlling the air conditioner, TV, bar and microwave from a single wireless remote control. But if it were only an expensive toy, then the market for building automation systems would not develop as quickly as it does now. Our company, having been successfully dealing with industrial automation tasks for more than seven years, decided to apply the accumulated experience in the field of automation of building engineering systems. In this article, we will try to figure out from the standpoint of a developer what is basically meant by building automation and why it is needed at all. We will take as a basis one of the projects we have completed, namely the project of automating the ventilation units of the Olimp car center in the city of St. Petersburg.

1. WHY IS IT NEEDED TO INSTALL BUILDING AUTOMATION?

building automation controller

The functional purpose of any building is to be a shelter from the external environment, to create comfortable conditions for a person to stay. In order for the conditions to be comfortable, in addition to the walls and roof, it is necessary to provide the proper amount of air (ventilation) and its quality (heating, air conditioning). It is also necessary to provide lighting, uninterrupted power supply, etc. Thus, we get a modern building, saturated with all kinds of engineering systems. To control these systems, an entire army of service personnel would be needed if it were not for automation. Therefore, automation is needed to reduce the cost of maintenance personnel. The quality of systems management also plays an important role. For example, a person will turn the tap of the heater several times a day, and the automatic temperature controller monitors its changes constantly and in real time. As a result, a stable temperature is maintained in the room, which does not depend on fluctuations in the air temperature outside the window and the temperature of the water at the outlet of the boiler room (by the way, the temperature of the water at the outlet of an automated boiler room is also more stable).

Consequently, due to the higher quality of control of the operation of systems, automation contributes to an increase in comfort in the building. And finally, the use of automation can reduce energy costs. Interestingly, Western authors single out lighting as the main component of costs (and typical Western developments in the field of building automation are mainly focused on lighting control), while Russian ones focus on heating. This is not surprising: firstly, the climate is colder in most of Russia, and secondly, electricity in our country is much cheaper compared to European countries. How can the use of automation reduce energy costs? Let's take a simple example. With an uncontrolled heating system, we will maintain such heat production that even in the coldest time, a comfortable temperature is maintained in the premises. As a result, when it gets warmer outside, it will be hot inside. Not only will the comfort decrease, but this is also a direct overspending of energy! The situation can be improved by an automatic system that provides exactly the temperature that is needed - as a result, energy costs are reduced. Naturally, this effect is achieved only in the case of well-thought-out control algorithms embedded in the automation system. It can be concluded that building automation systems perform three main functions:

1) increasing comfort in the building,

2) reducing the cost of maintenance personnel,

3) lower energy costs.

2. STATEMENT OF THE PROBLEM. DISPATCHING SYSTEM OR AUTOMATIC CONTROL SYSTEM?

After reading most of the articles on building automation, the impression remains that the main task is the remote control of all equipment from one dispatcher console. A lot of materials are devoted to the issues of building dispatching systems. But the level of automation is practically not covered, it seems that it is either not so important, or has already been worked out so much that there is nothing to discuss. In fact, the dispatching system provides only a reduction in personnel costs. But even here it is important that the level of automation ensures the collection of the necessary data. For example, often the system provides for remote control of ventilation, but there is no normal control of the state of the mechanisms. As a result, the dispatcher does not see whether the fan or the heater pump actually turned on at his command. Such a system is more harmful than useful: a rather expensive system has been introduced, the purpose of which is to reduce personnel costs, but personnel is still needed to monitor the condition of the equipment. As for providing comfort and reducing energy costs, the dispatching system does nothing at all. In order to provide the premises with air with the specified parameters, it is necessary to control ventilation and heating systems. Of course, this can be done by the person sitting at the dispatcher's console, but such control will be clearly suboptimal. Only automatic systems are able to monitor the air condition in real time and continuously regulate its supply, heating and cooling, not forgetting to switch between economical night and comfortable day mode.

When working on the Olympus project, we successfully solved the following tasks:

Creation of an automatic control system (ACS) for the ventilation units of the car center building in optimal modes, set from the dispatcher console;

Transfer of information from sensors and automation cabinets to a common dispatching console, which displays information about the operating modes of automation, the states of actuators and indoor temperatures in a convenient form.

So, when defining the task of building automation, it is necessary to understand that the grassroots level of automation is an important part of building automation systems. Maybe this level is so well mastered that it makes no sense to talk about it? We have seen that this is not the case. Further, we will show that both in the hardware base of building automation, and in the algorithmic and software, there are many controversial points that need to be paid attention to when designing, and that the solutions used in the implemented systems are not always optimal.

3. HARDWARE PLATFORM FOR BUILDING AUTOMATION

To avoid confusion, we introduce two classes of controllers used in building automation systems.

1. Configurable controllers are microprocessor devices in which a control program with a fixed structure is "hardwired". This can be a temperature controller, a relay control device according to settings, or an entire ACS of a ventilation unit with a heater and a heat exchanger. Such controllers have a system of settings that allows, to one degree or another, to adapt the ACS to the automated object. Programming consists of setting these settings through a menu system, much like programming a VCR to record your favorite show at a specific time. The disadvantage of such controllers is the lack of flexibility in case of changes in the source data. If a certain structure of the object was laid down during the design, and then something changed, for example, an additional fan was added, then the only solution is to change the controller.

2. Freely programmable controllers are controllers in the sense that industrial automation system developers are accustomed to. The processor module, equipped with means for interfacing with input-output devices, is programmed in any specialized language or in one of the standard programming languages. The current trend is such that, as a rule, languages of the IEC 61131-3 standard act as programming languages.

What is the reason for the coexistence of such different devices on the market?

The fact is that configurable controllers are mostly cheaper than freely programmable ones (although the price ranges are closing). This is understandable: these devices are simpler. It is also easier for an integrator to apply a ready-made solution than to develop his own program. Why then do we need freely programmable devices?

One of the answers has already been given before. The realities of our life are such that the constructed building can be quite different from the initial project. In this situation, the developer of the automation system must be able to adapt flexibly to changes without spending much money and time. Another reason for the use of freely programmable controllers is the ability to combine the control of various systems in one device. For example, one controller can simultaneously control both a large supply and exhaust system with a heater and a heat exchanger, and auxiliary small ventilation units. Thanks to the flexibility of programming, it becomes possible to combine installations according to the principle of territorial proximity to the automation cabinet, reducing the cost of the controllers themselves, cables, constructs ... As a result, despite the higher cost of freely programmable controllers, the system based on them, with correct design, is cheaper than based on configurable controllers. In addition, to work with a freely programmable controller, the APCS developer does not require special training (sufficient "industry-wide" knowledge and skills), which cannot be said about a configurable controller, and the experience of configuring controllers from one company is not very applicable to controllers from another manufacturer. All these considerations led us to the fact that our "general line" was the use of freely programmable controllers. We believe that such a solution is optimal for building automation systems -- Building management systems (BMS).

Rice. 1. Scheme of distribution of ACS cabinets (KSPA) for supply and exhaust systems of the Olimp auto center

The use of freely programmable controllers successfully solved the problem of automating ventilation units in the car center, despite the fact that they were of different capacities and geographically distributed throughout the building.

On fig. 1 shows the layout of the distribution of ACS cabinets for the supply and exhaust systems of the Olimp auto center. The cabinet of the ventilation unit control system in different views is shown in fig. 2.

Rice. 2. Cabinet of the ventilation unit control system

Our company has long and successfully used I/O modules and PROFIBUS slave node controllers from the WAGO I/O family of the 750 series from WAGO (Germany). For example, the use of these devices in automatic control systems of automobile gas-filling compressor stations (one of our implemented projects) showed their high reliability, extreme ease of installation and maintenance.

WAGO I/O 750 series equipment is widely used in industrial automation, and more recently in building automation. Among the building automation projects made on WAGO I / O controllers are such “monsters” as the Bosch headquarters, the Hamburg Police Headquarters, the Daim-ler-Benz (Mercedes) center in Potsdam, the Central Bank of Saarbrücken, etc. .d. There is already domestic experience in the use of these controllers in projects for the automation of buildings of banks, shopping and entertainment centers, cottage settlements.

All these facts influenced the fact that we chose the WAGO I/O 750 series programmable controllers for building automation. Looking back, we can say: we did not regret our choice.

4. ALGORITHMS FOR CONTROL OF VENTILATION AND HEATING

One of the main sources of energy costs in our cold climate is heating. When automating building systems, a balance must be found between comfort (desired temperature) and cost reduction (achieving the required temperature with minimal energy consumption). An effective way to reduce heating costs is the use of recuperation. A heat recuperator is a drum or tube-type heat exchanger, with the help of which part of the heat from the exhaust air is transferred to the cold supply air coming from the street. The efficiency of the heat exchangers is very high: the heat exchanger in the supply system heats the air coming from the street from -20 to +10°C. But without an automation system that regulates heat transfer, quite large fluctuations in the supply air temperature can be obtained. In addition, the heat from the heat exchanger may not be enough, and then you need to use the heater. In order for the heating to be the most efficient, the control of the heat exchanger and the heater must be coordinated with each other: only when the capabilities of the heat exchanger are fully used, the automation should turn on the heater. It is no coincidence that manufacturers of automation for ventilation systems abandoned the management of individual subsystems a long time ago and began to create unified ACS for air handling units.

The task of controlling the heater, at first glance, is quite simple: it is enough to control a three-way valve, regulating the supply of coolant depending on the current and set temperature in the heated room. But the problem is that the coolant is ordinary water, which means that in winter there is a danger of freezing. To avoid this, the control algorithm is usually supplemented with one of the following solutions:

Giving a command for full opening (or a fixed opening value) of the heater valve when diagnosing the danger of freezing;

Prohibition of closing the heater valve when diagnosing a risk of freezing.

Both solutions have significant drawbacks. If the automation system opens the valve completely at any risk of freezing, the frost protection task will be fulfilled, but the energy consumption will be increased, and the temperature in the heated room will be slightly higher than the target. If the automation blocks the position of the valve, prohibiting its closure in case of a risk of freezing, then due to the thermal inertia of the object, the temperature may drop below the point at which the blocking was triggered, and this may lead to freezing. Therefore, when setting up the automation system, the freezing setpoint has to be artificially raised, which again leads to an increase in heat consumption and maintaining a slightly elevated temperature in the heated room.

We have developed a scheme in which the valve always opens exactly as much as necessary. Its principle of operation is determined by several independent feedback loops and a minimum selector.

The feedback loops for the temperature in the heated room, the temperature of the return water in the heater and the air after the heater operate independently, ensuring a smooth transition from one controlled value to another. As a result, if the heater approaches freezing, no abrupt switching of control actions occurs. The limiting circuit takes control without shock and begins to stabilize the temperature of the water or air behind the heater, keeping it at the minimum safe level. Often, when creating building engineering systems, developers save on binding actuators with feedback signals. And indeed, why put end position indicators on the damper and enter these signals into the automation system, if a damper that does not work does not lead to something catastrophic? The fan will most likely not be broken if it works for some time with the damper not open, and due to unusual noise, the defect will be quickly detected and eliminated.

But if you think about it, this approach contradicts the very idea of an intelligent building. The point of introducing expensive automation is to reduce operating costs. And this can be achieved by reducing energy consumption and reducing the number of staff. What kind of reduction in energy consumption can we talk about if the fans work "into the wall" from time to time? And if the automation cannot detect a malfunction on its own, then personnel should deal with such detection. In a large building, this means a large number of workers and continuous rounds of equipment. Why then do we need an automation and dispatching system? It turns out that the desire to save money on completing the automation system turns into a decrease (possibly to zero) of the economic effect from the implementation of the system. The use of various feedback sensors (limit switches, control damper position sensors, etc.) in combination with flexibly programmable controllers allows you to create a truly “intelligent” system that not only switches equipment according to a given program, but can also inform the dispatcher about defects equipment. Let's imagine that in a shopping center at the ventilation unit, when trying to turn it on, the supply air damper did not open. Automation waits for a while, holding the command to the damper mechanism, after which it issues an alarm and does not turn on the supply fan. The dispatcher, having received the signal “Inlet damper No. 7 at the P5 unit did not open”, can take action in time, promptly sending repairmen to the right place. As a result, the defect will be quickly eliminated, visitors to the trading floor will not notice any stuffiness or uncomfortable temperature, and the store owner will not suffer losses from increased energy consumption. It should be noted that in industrial automation systems, control of actuation of actuators is a completely common practice. It can be argued that the cost of failure, for example, on a gas pipeline is a possible accident that can cause enormous damage, and even lead to human casualties, while in the ventilation system it is just relatively small losses. But it is precisely for the sake of reducing such losses that building automation systems are being introduced! Therefore, in our opinion, it is necessary to put into the system at the design stage such solutions that will help diagnose the state of the mechanisms and make prompt decisions in case of any malfunctions.

In some cases, one control of actuators is not enough.

For example, it is not enough to check that the starter of the heater circulation pump has tripped. If the starter worked (the automation and dispatching system received a signal that everything was in order), and the pump did not start for some reason, then the heater will not work normally: there is no coolant inflow, which means there is no heat transfer. The dispatcher will only see the fact that the heater controller for some reason cannot maintain the set supply air temperature. This is exactly the situation we observed at one of the objects. And it is quite simple to correct the situation: it is necessary, when designing, to lay a flow switch behind the pump into the system and control the presence of flow during the operation of the pump. Moreover, such a simple solution will in some cases prevent equipment breakdown by turning off the pump when there is no water in the circuit. The rating of individual algorithmic solutions in building automation systems reflects Table. 3. From this table it can be seen that well-thought-out control algorithms slightly increase the price of the system, but at the same time its characteristics are significantly improved. Conclusion: one should not save on a good study of control algorithms and on obtaining information about the state of the object. And here the advantage is the company that performs all stages of development, starting with the project and technical specifications, and has the ability to independently develop application programs.

5. NETWORK FOR COMMUNICATION WITH THE DISPATCHING SYSTEM

Building automation devices are integrated into the dispatching system using a computer network. During the existence of computer networks, a lot of network protocols have been created, which have their own advantages and disadvantages. When creating an automation system, you need to choose the best option. "Natural selection" in the market did its job, and frankly unsuccessful network protocols simply disappeared. Comparing “surviving” protocols only by technical characteristics is a thankless task, since in the field of building automation, as in no other field of automation, estimates are highly dependent on commercial, organizational, technical and simply subjective factors and therefore cannot differ in absolute reliability. Nevertheless, manufacturers of various equipment often arrange real battles on the Internet forums and in the press about this. Let's try to understand the features of the application of the most common protocols. For some reason, historically, this industry has gone its own way, and the main network protocols used in building automation systems are not used anywhere else. We have not been able to find objective reasons for this.

Building automation does not impose any special requirements on the networking system. The solutions used here are also not cheap. Therefore, it remains only to repeat: the situation has developed historically. We failed to understand what advantages specialized protocols for building automation systems have over universal protocols. For example, the only advantage of Lon Works is a large number of smart devices that support this protocol. But in general, in our opinion, if the system is created from scratch, then the use of generally accepted universal protocols (for example, Ethernet TCP / IP and HTTP) allows you to eventually create a simpler, more reliable and inexpensive solution. In this sense, the title of an article by William R. Elam, included in the review “View point: BAC net versus Lon Works” (“View point: BAC net versus Lon Works”), -- “Internet Beats Them Both (“Internet beats both”).

It would be wrong to say that only the use of specialized protocols makes it possible to automate large buildings. So, for example, in the Olimp car center, where our ACS for ventilation units is implemented, the dispatching network uses the ModBus / RTU protocol in the RS-485 environment.

CONCLUSION

Building automation is a rapidly developing, but relatively young area of technology, so here, especially at the levels of management of engineering systems and life support systems, there are practically no well-established technical solutions that go beyond the private solutions of individual firms. We are convinced that developers of building automation need to pay attention to the developments that exist in industrial automation systems. Our experience shows that the principles of creating automated process control systems and building automation systems are generally similar, and the use of solutions proven in the industry allows you to quickly create a high-quality system. And with the optimal selection of components, its cost will not be as high as it might seem. The authors do not claim to be infallible, but they assure that their position is deliberate and not biased.

What subsystems can be controlled?

The concept of "Smart Home" is a fairly common phenomenon in modern society. The automation system allows you to control absolutely all electrical appliances and engineering systems, monitor the correct operation, even when you are far from home.

Building automation works on the same principle, but on a larger scale. Thanks to it, you can control:

power supply - you can control the supply of energy to all consumers, carry out quality control in normal and emergency mode, monitor line overload, check the health of elements (substations, power cables, batteries, etc.), turn on economy mode and much more
lighting - you can control the switching on and off of the lights on the landings, in duty and emergency rooms, supply light to certain parts of the building at certain times, control the lighting in the yard and obstruction lights
heating and hot water supply - you can control the heating system, check the air temperature in the room, check the correct operation of pipelines, monitor the state of feeding circuits, pressure, and so on.
cold water supply - you can control all process equipment, maintain optimal pressure in pumps, check drinking pumps, fire systems, water filters, monitor the condition of pipes and much more.
ventilation - automatically maintain the optimum air temperature in the premises, check the state of moisture in the entire building, in individual blocks, turn on or off individual objects or the entire ventilation system if necessary, check energy consumption, and more
climate control - individual or decentralized in separate rooms and rooms control of climate, humidity, heating and ventilation systems
security - checking the performance of all video cameras, sensors, alarm systems, turning them on / off, controlling power consumption, managing the system in emergency mode, and more
engineering systems - checking the condition of all drains, sewers, roofs, basements, monitoring water leakage, gas contamination, the environment, elevator equipment, energy metering and much more.

The above parameters can only give a general idea of what and how can be controlled in building automation. Thanks to this “smart” system, absolutely all engineering systems and devices are under control: if a breakdown occurs somewhere or a pre-emergency situation occurs, the “Smart Home” system instantly reacts, blocks the operation of a particular section and notifies of a breakdown.

Benefits of building automation

In modern construction, this task presents a number of advantages, both for investors and for residents and even for maintenance services. Let's look at some of the benefits:

investors - the value of the building increases and its status rises; the service life of the entire building becomes longer, which leads to a decrease in accidents and emergencies, which increases the interest of landlords.
operational services - you can create one information space to increase the functionality of the services; coordinate the work of all automated engineering systems of the building; high level of resource management; reducing costs and improving working conditions
residents - comfort; security; cost reduction

It is advisable to implement automation at the time of building construction or major repairs, since in order to combine all engineering systems into one control system, it is necessary to carry out verification work in advance, make sure that all devices and systems are working properly and will not require replacement in the near future.

After that, all parameters of residential, municipal and commercial premises are assessed, where all the nuances must be taken into account, because they can greatly affect the operation of the system. After such verification is carried out, a work plan is drawn up for the installation of hardware, software and related sensors.

The next step is to install the system and test it. Since the “smart home” independently controls absolutely all engineering systems, it takes some time for the program to study the load on various installations at different times and work schedules. After the program receives all the necessary data, the most optimal mode of operation and control is set.

Automation can be carried out both comprehensively and in stages.

Ventilation and air conditioning systems are designed to supply fresh air and remove harmful impurities that form indoors (carbon dioxide, dust, etc.), clean, heat or cool the supply air. Separately from the main ventilation system, fire ventilation (smoke removal systems) operates.

Residential and industrial buildings in Moscow cannot do without a number of automation and control systems for engineering systems, which are carried out with the help of modern automation. The heating network of the building, power supply, ventilation and air conditioning networks require special equipment for automatic control of work. Residential building systems also need to account for consumed resources and carefully monitor the operation of all engineering systems. Our company produces automation of engineering systems in Moscow, with the help of which automatic control and dispatching is carried out.

Ensuring engineering infrastructure dispatching

The dispatching system of engineering systems is a way to control the distribution and accounting for the consumption of various resources used during the operation of a building. If the dispatching system is installed in production, then it also performs the functions of monitoring and controlling all parameters of production activities. The engineering systems dispatching system is introduced into the automation system and allows you to control all parameters of the infrastructure of a building or production. Our company produces high-quality and reliable equipment for the automation of engineering systems.

With the help of automation and a dispatching system for engineering systems, significant savings in energy, water and other resources can be achieved. Such a system will help to control the level of safety and reduce the risk of an accident at the facility.

In large industries, as well as in residential complexes, there is always a risk of a fire, a breakthrough in a heating main, a power outage or a gas leak. In order to minimize the risk of such incidents, the engineering systems dispatch system we install is equipped with the most modern computer equipment with sound alarm sensors. In an emergency, the system will give a warning signal to the control room and alarm devices. This approach allows minimizing the impact of the human factor and promptly responding to changes in the parameters of engineering systems and making timely adjustments to work processes.

All equipment for the automation of engineering systems, which is produced by our company, meets all the requirements for the quality of this type of product, and has all the relevant certificates. When creating a project for an automation system for buildings and structures, we use an individual approach to each client. You can contact our support team and get a free consultation.

In the modern world, any building, both industrial and residential, has an extensive network of various devices and units, combined into systems and complexes that ensure normal and comfortable use. For example, this is water supply, energy supply, air conditioning. To simplify the operation of complex complexes, automation of engineering systems is used. This reduces both the time for maintenance and control, and the consumption of energy resources. When building such systems, two approaches are used:

Fully automatic operation a complex of equipment, in this case, a person is involved only in the design, production, installation and commissioning. Further intervention is not required.
semi-automatic, or as it is also called automated - management decisions are made by a person. Same way the creation of an automated control process is called dispatching.

Dispatching of engineering systems is used to control the operation of equipment. The use of this technique allows you to optimize the time of work, which reduces operating costs. You can automate anything - electricity, heating, air conditioning, water supply. Thanks to this process, energy consumption is reduced and energy consumption is optimized. All this is achieved by the development of optimal functioning algorithms - they use various sensors (motion, volume, lighting, temperature), switching modes depending on the day of the week and time.

Before starting work on automation, you need to determine:

What part of the equipment needs to be automated?
Which approach will be implemented: simple or complex?
The equipment will work with or without human intervention.
Economic effect.

After that, specialists, based on the discussions and calculations obtained at each stage, develop an automation algorithm. According to this algorithm, hardware and software solutions are selected, installation, adjustment, configuration and testing of the entire complex is carried out.

Despite the seemingly high costs of creating and implementing process control systems, the economic effect of their use is quite significant. The costs of creation are returned within 3-5 years. Then the net savings begin, thanks to the rational use of energy and other resources.

The process of supporting such embedded solutions takes into account the specifics of the construction and includes the maintenance of sensors, the readings from which are used in the process of operation, signal and control circuits, control valves, shut-off valves and other parts.

Autonomous Technologies specialists have extensive experience in creating, implementing and maintaining automatic and dispatched control systems. This allows you to perform all operations quickly, efficiently and on time.
