What is building automation?

Question 1: What is building automation? Building automation is a part of intelligent building, that is, using computer and other control equipment to realize information collection and automatic control of various systems, mainly including:

Air conditioning/fresh air system

Cold and heat source system

Substation/distribution system

Water supply/drainage system

Air supply/exhaust system

illuminating system

Elevator system

Question 2: What is building automation? In recent years, people think that the future buildings will be full of all kinds of intelligent devices. The sensors, actuators and valves in the building control network are all intelligent, and the infrastructure of the building can seamlessly connect the data network and the control network to form an integrated building network.

The whole building network will become the model of future building control. In 1990s, people gradually formed a new concept of building automation information transmission:

Intelligent devices-sensors and actuators form an autonomous control environment, that is, intelligent temperature sensors, light switches, curtains, elevator buttons, card readers and so on can work together.

Network-A new generation of smart devices can seamlessly connect various networks, such as the Internet, corporate networks or building wide area networks and local area networks.

Global networking-With the development of networks, devices and systems, users can remotely access anywhere on the intelligent building network at any time in the world.

The whole concept of building a network is no longer an expectation for the future, but it is happening today. Manufacturers providing intelligent devices, subsystems and systems are growing exponentially. This driving force mainly comes from the owners, who demand higher and higher integration degree of building property, which is also reasonable. Because today, intelligent products in building automation subsystems such as access control, closed-circuit television, elevators, air conditioning, HVAC, security and fire protection have all come out.

Although many intelligent products are gradually updating the building subsystem, the real building network system is still rare. On the one hand, manufacturers show that they are completely close to open systems, but on the other hand, they restrict the development of interoperable products because they are afraid of market changes brought about by standard network communication protocols and truly open structures. Big companies are willing to maintain the status quo because they have vested interests. Many large manufacturers apply L0NWORKS technology to their underlying devices, because they find that L0N WORKS platform, an economical and effective technology, can realize the communication between devices in their closed systems, but they are only willing to do so.

As long as we review the development history of modern science and technology, we can see the danger of this phenomenon. In the 1960s and 1970s, some giants in the computer industry, such as IBM, Burroughs, Control Data, sperry, NCR and Honeywell, monopolized the computer market. Their equipment is huge, closed and expensive. In 1970s and 1980s, some new computer companies appeared, such as DEC, Data Geheral, Tande and Wang An Computer. The computer products of these companies are relatively distributed, but they are still expensive closed master-slave systems.

In 1990s, another group of computer companies replaced the leading position in this industry: paq, Dell, Gateway and Hewlett-Packard. These new companies can achieve such results because their products are completely open, cost-effective and flexible. With the increase of sales channels, manufacturers can cut costs and expand the market to get more profits.

Towards development

Today's building automation industry has many similarities with yesterday's computer industry. The traditional building control system is also closed, usually purchased from a company and installed by them. Because this system is a master-slave control structure, the installation and maintenance costs are high, and the future increase, decrease, modification and maintenance have certain limitations. Any integration at the subsystem level requires expensive gateway hardware and professional editors to complete.

Unfortunately, many control system manufacturers are unwilling to provide a truly open platform.

Look forward in the rearview mirror.

If we carefully observe all kinds of products provided by building automation manufacturers in the market today, we can't help wondering whether these manufacturers are looking forward in the rearview mirror. What the end user wants is an open equation system, excluding those expensive, exclusive and closed templates and central controllers, as well as the corresponding complex wiring, control procedures and maintenance.

Today's control equipment manufacturers want to integrate their expensive gateways (achieve interoperability). Although these gateways can interoperate subsystems to some extent, they restrict the communication between terminal devices and complicate the whole system. Intelligent routers can ... "";

Question 5: Building Automation System (BAS) What does BAS involve? Modern buildings usually include all or most of these devices. With the increase of building scale and the improvement of standards, the types and quantities of these devices have increased dramatically, and the number of monitoring and control points required can reach thousands to tens of thousands. These equipments and measurement control points are generally scattered in all floors and corners of buildings, so decentralized management, on-site monitoring and operation will occupy a lot of human resources, and sometimes it is almost impossible to achieve. Using computer and network technology, centralized management and automatic monitoring of these devices is of great significance to save operating manpower and keep the equipment normal. At the same time, related equipment can be started and stopped in time through the computer system to avoid unnecessary operation of equipment and save energy consumption in system operation. In this way, the main purposes of BAS system are: to improve the management level of the system; Reduce the workload of maintenance management personnel; Save energy consumption in operation. BAS subsystem: 1 power supply system 2 lighting system 3 air conditioning system 4 water supply and drainage system 5 fire protection system 6 security system 7 traffic system 8 centralized management and coordination of BAS. Although the system in BAS is complex and diverse, the bottom layer is still various sensors for detecting various physical quantities, various actuators for executing control actions, and field computers directly connected to these sensors and actuators (also known as DCU, RTU, DDC substation, etc.). ). These field computers receive the corresponding sensor information, convert it into digital signals, and send them to the upper management computer at any time, and then drive the actuator to complete the required control and adjustment tasks according to the command of the upper management computer and the system state measured by the sensor. Different monitoring objects involved in the system will make sensors and actuators very different. In the previous lecture, the system configuration of cold and heat sources and water system of this level air conditioner has been discussed in detail. Power, lighting, water supply and drainage systems are different except for sensors and actuators. The structure and basic configuration ideas of this level are the same as those of air conditioning systems. The main feature of the fire protection and security system is the use of multiple probes in bus mode. The bus is connected to the area controller, where it is decoded to determine the output state of each detector. In this way, the area controller is similar to the field controller, so there is no great difference between subsystems above the field controller level. The problem to be studied is how to connect the field controllers distributed all over the building and realize the data exchange between them. How to set up the management computer of each subsystem and the general management center computer of BAS, and what kind of management configuration software is suitable for system management and control.
