In modern society, there are more and more requirements for convenience in all aspects. The construction industry integrates information technology into the construction process. It also improves the modernization and intelligence of building buildings to a certain extent, and can more ensure the safety and comfort of residents. . In the process of building an intelligent building, it is necessary to use a computer network and an intelligent system that is installed inside the building. Through the network and intelligent systems, intelligent devices within the building can be manipulated without the need for the occupants to personally switch the device. According to the need to control the device's time switch, smart devices can also guarantee the safety of residents to a certain extent.
1. Systems used in intelligent building buildings
1.1 Building Automation System
The building automation system is used in intelligent building buildings. In order to achieve better management of smart buildings, it is necessary to connect various intelligent devices through computer network technology, improve the building environment of intelligent building buildings, and put buildings inside buildings. The various devices are well managed. Intelligent devices in intelligent building buildings are usually monitored in real time, and the data generated during the operation can be recorded to facilitate troubleshooting in the event of a failure. The state of each electronic device in intelligent building buildings can be checked. Adjust to the best and avoid delaying production construction due to malfunction of electronic equipment. Under different environmental factors, appropriate adjustments must be made to the equipment so that the equipment can adapt to the environment more safely and reliably [1].
1.2 Communication Automation System
Through the use of a communications automation system, it is possible to connect the entire world, facilitate the user's communication with the outside world, and realize the transmission of information within the intelligent building. All this is achieved through the network. On the basis of the network, internal information transmission is carried out through the lines laid inside the intelligent building, and after connecting with the external lines, communication with the outside world can be realized.
1.3 Office Automation System
In the process of intelligent building management, property workers need office automation systems to perform smart building management. In the office automation system, daily office tasks can be handled. The management staff of the intelligent building management mainly manages several aspects of daily management, and the construction environment and safety work of intelligent building buildings are done well. Real-time monitoring of water usage in buildings.
1.4 Structured Integrated Cabling System
In the intelligent building building, the intelligent integrated building wiring system is used to realize the connection of various communication devices in the intelligent building. The voice and information can be transmitted within the intelligent building. This is based on the establishment of the structured integrated wiring system. To achieve this, we must also conduct line connections outside the building of intelligent buildings. By combining the internal routes of intelligent building buildings with the outside, we can communicate with the outside world.
1.5 Computer Network
All operations in intelligent building buildings are inseparable from the support of the network. There are many types of computer network options, the main choices are Ethernet, integrated services digital network.
2. Composition and Development of Distributed Control System
In the distributed control system, the 4C technology is mainly used to realize the function of mutual communication between systems. There are two parts in the DCS system. The first part is the hardware part. People mainly realize the hardware parts of the DCS system. The operation includes a major part and a minor part in the entire process of control management. In the main part, there is a centralized operation management device. In the secondary part, there are distributed process control devices and other devices. The hardware devices are the basis of the communication network. On the connection, each device of the hardware is connected to realize the operation control of the entire system and complete the functions possessed by the system [2]. The main part of the software installation is the ability to process and analyze the monitored data. There are many types of software and they are all developed according to actual needs. There are many types of DCS systems, but they are all in a certain degree. There are three basic parts in the DCS system. These three parts complement each other and jointly complete the overall functions of the DCS system. Among the distributed process control devices, the data acquisition device and the programmable logic control are used. Devices and single-loop controllers and other equipment components play an important role in the DCS system. The basic structure of the distributed control system is shown in Figure 1.
1) In the first-level centralized control system, there are many field control devices. Through the role of the field controller, the field control devices are connected, real-time monitoring and adjustment are performed, and debugging is performed according to the different states presented by the system. The central monitoring computer is Under the guidance of the guidance, the transmission of the instruction of the on-site monitoring equipment and the data monitored by the field control equipment are recorded and analyzed, and appropriate solutions are proposed to solve the related problems. When the establishment of a large-scale distributed control system is needed, The establishment of the subsystem, through the joint action of all levels of subsystems to achieve the control of the entire system.
2) In the second-level distributed control system, the central monitoring computer is used to monitor and command the entire system, and the data monitored by the monitoring equipment is processed through the use of computer software at the main station, and these scenes are transmitted. The data is classified and recorded, and the necessary data is printed out to the relevant technical personnel for reference. In order to ensure safe operation during the operation of the system, it is necessary to separate the workstations. The separation of workstations can improve the overall system security performance. During the process of production management, detailed records shall be made of the real-time entry and exit conditions of the goods in the warehouse, and the basic conditions of the goods in each subsystem are collated, and the real-time management of the goods can be performed according to the data conditions, and the goods The structure is adjusted to adjust the proportion of the goods to an appropriate state and achieve a more substantial revenue. The use of distributed control systems can also help management personnel perform personnel mobilization and financial management when conducting business management.
3, the application of distributed control system in intelligent buildings
In the construction process of intelligent building buildings, distributed control systems are usually used, but generally only two levels are set. Although there are only two levels, they can better meet people's demand for intelligent building buildings. Intelligent building When building a distributed control system, intelligent electronic devices in intelligent building buildings may be connected through a computer network to achieve remote real-time monitoring of electronic devices in intelligent building buildings. Computer network access is also available. Can increase the intelligent building control intelligence, intelligent building buildings with rich functions can provide users with a more smooth experience, the use of distributed control devices in the distributed control system can improve the safety of intelligent building buildings[3] . In the traditional control system, there is a problem that the control function is concentrated on one device and the risk is too high. Once the equipment used for monitoring fails, the intelligent building buildings are prone to safety problems, and the decentralized control device can To reduce this risk, a number of hardware devices that help users use management are also used in distributed control systems. Connecting hardware devices such as printers and display screens to distributed control systems can bring more intuitive and convenient users to users. Experience, distributed control system in the application of smart buildings in many areas, in all aspects have a specific performance, can be fully demonstrated, in some shopping malls on each floor for intelligent building requirements Different, according to different needs need to install different control devices, commissioning work must be adjusted according to the different floors, each floor to install the subsystem. When each floor has different requirements for intelligent building buildings, the subsystems can be directly debugged without having to make major changes through the overall system. Such a distributed control system that allows the subsystems to communicate with the general system can work well. Adapting to the needs of users, the system divides the areas with different directions of use, and regulates the functions of a certain area to control the required direction, as shown in Figure 2:
