Keywords: building automation system, the core principle of the basic functions of hardware and software technologies1 Introduction to Building Automation System, also known as building automation system (BuildingAutomationSystem referred to as BAS), is an integral part of intelligent building, its task is the building39。s energy use, environmental, traffic and safety monitoring, control, etc., to provide a safe and reliable, but also save energy, and fortable work or living environment automation system ponents and basic functions of building automation systems often include air conditioning, water supply and drainage, power supply, lighting, elevators, fire safety and prevention and other subsystems. According to our industry standards, BAS can be divided into equipment operation management and monitoring subsystem and fire prevention and safety subsystems, as shown. In general, these two subsystems together into BAS consider should, if the fire and safety precautions Ziji Tong independent setting, control center should be established munication with the BAS contact Yipian disaster Fasheng, can achieve the agreed operating Quan Zhuan Yi An Zhao, Jin Xing Yi Tihua coordination and contro.Building automation system39。s basic functions can be summarized as follows: (1) automatic monitoring and control of various electrical and mechanical equipment, the stop, display or print the current operating state. (2) automatic detection, display, print a variety of electrical and mechanical equipment operating parameters and changes in trends or historical data. (3) According to external conditions, environmental factors, the change automatically adjust the load of equipment, so that is always running in top condition. (4) monitoring and timely processing of all accident emergencies(5) to achieve a variety of electrical and mechanical equipment on building a unified management, coordination and control. (6) Energy management: water, electricity, gas metering and charging, etc., to achieve energy management automation. (7) Equipment
