There are a large number of mechanical and electrical equipment in modern intelligent buildings, such as central air-conditioning systems, ventilation systems, cold and heat source systems, water supply and drainage systems, elevator systems, lighting and other system equipment. These devices are many and scattered. Many, that is, a large number of objects to be controlled, monitored, and measured, up to more than a thousand points; scattered, that is, these devices are distributed on each floor and every corner. With decentralized management, local control, monitoring, and measurement are unimaginable. , 并创造安全、舒适与便利的工作环境，提高经济效益。 By adopting the building automatic control system, it is possible to rationally use equipment, save energy, save manpower, ensure the safe operation of the equipment, strengthen the modern management of mechanical and electrical equipment in the building , and create a safe, comfortable and convenient working environment, and improve economic benefits.
2. Overall design ideas and principles
Intelligent buildings have a large building area and complex building functions. To this end, a large number of electromechanical equipment is configured to ensure a good and comfortable environment and convenient working space for the entire building. The use of a large number of electromechanical equipment will inevitably cause an increase in management staff, huge expenditures on energy consumption costs, and complexity in management work. Therefore, according to user requirements and referring to related drawings, we believe that the requirements of this building's automatic control system are actually reflected in three levels:
n technical level
This project is a super high-rise comprehensive building integrating self-use office, apartment, catering, and commerce. The building should provide multiple use functions to serve the owner's overall operation and development services. BMS 系统应采用当今先进且成熟的系统及技术，为建筑物的运行提供高效的监控及管理平台，同时亦应为业主企业的运营与发展服务。 Therefore, from a technical perspective, its BMS system should use today's advanced and mature systems and technologies to provide an efficient monitoring and management platform for the operation of the building, and it should also serve the owner's business operation and development.
· BMS system architecture based on TCP / IP and open protocols
The management network is required to support the TCP / IP protocol, and the central station can transmit information to any designated data communication substation through the network. The field control network requires a network that complies with the BACnet communication protocol, and the field controller can complete the control function independently of the network.

n Building operation management level
All systems and technologies are for building operation. When the technical level requirements are met, the system control, operation and management modes designed for the functional characteristics of the building are to ensure that the building is efficient, low-consumption and energy-saving. The key to running. It is embodied as:
· Control of operating conditions of air-conditioning system
That is, according to the change of outdoor weather conditions, the control and adjustment of the operating conditions of the refrigeration station and air conditioning system are optimized to maximize the operating efficiency of the entire air conditioning system on the basis of meeting the indoor temperature and humidity and indoor air quality parameters.
· For different functional areas in the building
Based on the operating condition control of the air-conditioning system, specific regional control modes for different functional areas are implemented to meet the specific needs for indoor air parameters in different functional areas.
· Maximize building air quality
The air flow organization and micro-pressure difference monitoring and control between different functional areas in the building can achieve more reasonable air flow distribution and pressure difference parameters between the areas, and ensure the maximum air quality in the building.
· Acquisition of operating parameters of power distribution system
Real-time collection and monitoring of the operating parameters of the power distribution system and the recording of historical data, provide a standard database format and database retrieval application interface, and organize, analyze, and archive historical data. It is convenient for operation management to understand the distribution of power loads in the building. Make data analysis and comparison to provide data foundation and analysis methods for improving building power distribution management.
· Water supply and drainage system monitoring
Decentralized control and centralized monitoring and management of the water supply and drainage system. The equipment of the water supply and drainage system is more decentralized and relatively independent. The centralized monitoring and management of the liquid level status and alarms of all water tanks, pools and puddles.
· Lighting system monitoring
Personalize the lighting of public areas and special areas, optimize the lighting control mode, and optimize the control mode to maximize the energy-saving operation of the lighting system on the basis of meeting the lighting function requirements.
· Central Management Platform
The central management and monitoring platform based on the enterprise's general database, IE and WEB technologies provides a personalized management operation mode and open application interfaces and tools to achieve a complete decentralized control centralized management operation mode and provide overall management for the operation of the building Run the service.
n Enterprise operation level
BMS 技术是为建筑物的运行管理服务的，完备的建筑运行管理又是为其服务的企业运营发展而服务的，同时又直接关系到物业管理企业的运营绩效，因此 BMS 系统运行管理模式亦应体现为企业运营服务的层面上。 Advanced BMS technology is for the operation and management of the building. Complete building operation management is for the operation and development of the enterprise it serves. At the same time, it is directly related to the operation performance of the property management company. Therefore, the BMS system operation management mode It should also be reflected in the level of business operations services. It is embodied as:
· Systematic integration into the overall management system of the owner's enterprise
The standard database and network technology are integrated into the owner's enterprise's overall asset management system to achieve the overall management of its assets.
· Improve the comfort of users' operating environment
To improve the satisfaction of users and their customers, one of the main purposes of the application of a large number of electromechanical equipment is to bring convenience to daily work and life, while also ensuring the comfort and safety of the environment. The application of building automatic control system fully respects and adheres to this principle, and all control measures and energy saving measures must not violate this basic point. Moreover, it is the use of a building automatic control system that enables us to monitor the environmental indicators more intuitively and conveniently. Through analysis of the building control system, we can control air conditioning, ventilation and other equipment to ensure the comfort of the environment. The control system can effectively ensure that the change in ambient temperature is not greater than +/- 20C, which cannot be achieved by traditional processes. The building automatic control system can also monitor the comprehensive environmental quality, such as the content of indoor CO, CO2, and other harmful substances. Once it exceeds the standard, the linked blower and exhaust fan will supplement the outdoor fresh air in a timely manner to exhaust indoor foul gas and ensure the cleanness of the indoor environment.
· Energy saving and energy management
Through advanced technical means and optimized control and management modes, monitoring of building energy consumption, data collection, and energy performance analysis are achieved, and the most energy-efficient strategies are used to achieve continuous improvement in energy efficiency. The building automatic control system monitors and controls the electromechanical equipment of the entire building through computer control programs, and uniformly allocates the power consumption of all equipment, which can achieve the optimal control of the power load, effectively save energy, and reduce unnecessary waste. As a modern building, the power consumption of this project is very amazing. The various equipment in the building are "big consumers". Take the air-conditioning system as an example, the power consumed here is even more amazing. After the building is equipped with a building automatic control system, the system can calculate the actual cooling load of the building and the unit based on the data detected by sensors installed throughout the building. If the capacity is much richer, it means that it is not necessary to start all the equipment groups. Shut down one of them in the order specified in the program. If the capacity is still much richer, turn off the second one in order. Conversely, when the cooling load increases, the equipment is sequentially turned on. By adjusting the equipment to turn on, it not only guarantees normal needs, but also reduces energy consumption. Currently, there are tens of thousands of buildings in the world using building automatic control systems. In these buildings, under normal circumstances, the energy saved can reach 20%, and this benefit can never be achieved by manual operation.
· save human effort
The advanced management and monitoring platform of the building automatic control system can greatly reduce the operation and operation personnel and equipment maintenance and repair personnel after being put into use, and can timely deal with equipment problems and improve the work efficiency of personnel.
· Extend equipment life
After the building automatic control system is configured in the building, the operating status of the equipment is always under system monitoring. The building automatic control system can provide a complete record of the equipment operation, and at the same time, it can print out maintenance and maintenance notices regularly. Equipment maintenance is carried out in advance and without delay, and equipment failures and hidden dangers can be found and dealt with in a timely manner, so the operating life of the equipment can be extended, that is, the operating cost of the building can be reduced.
· Ensuring building and personal safety
In addition, the safety of the building itself and the safety of people's lives are very important. The advanced building automatic control system can integrate security management and parking management in the same system, and can be easily connected to the fire alarm system, so it can greatly improve the management level of the building and reduce coordination between departments. In the United States, when the building is insured, buildings equipped with the building automation system can enjoy great concessions, which shows the importance of the building automation system.
3. An Introduction
The main working properties of electrical equipment in buildings, such as elevators, pumps, fans, and air conditioners, are strong electric drives. Usually these devices are in an open working state, which means that they do not form a closed loop. 节约能源 。 As long as the power is turned on, the device is working. As for the working status, progress, energy consumption, etc., data cannot be obtained online and in time, let alone reasonable use and energy saving . 行程开关 、光电控制等，对设备的工作状态进行检测，并通过线路返回控制机房的中心电脑，由电脑得出分析结果，再返回到设备终端进行调解。 Now the building self-control is to monitor the above-mentioned electrical equipment online, detect the working status of the equipment by setting corresponding sensors, travel switches , photoelectric control, etc., and return to the central computer in the control room through the line, and the analysis result is obtained by the computer , And then return to the device terminal for mediation.
