Research On Building Power Supply And Distribution System Based On PLC

In recent years,with the rapid development of Chinese national economy,high-rise buildings such as bamboo shoots after a spring rain like appearance,the conventional power supply system has been unable to keep pace with the times,the efficiency of complex structure,low and rely entirely on manual operation,does not conform to China's energy-saving emission reduction to promote the concept of environmental protection,therefore,intelligent the building has been favored,in this context,the automation of distribution systems of intelligent buildings is particularly important.This article mainly aims at the building automation supply and distribution system,provides a new idea for the development of power supply and distribution technology.Firstly,this paper analyzes the current situation of building automation power supply and distribution system based on PLC,and expounds the basic requirements for the design of building automation power supply and distribution system,summarizes the common problems in building distribution system.According to the actual conditions,this paper puts forward the overall design scheme of the simulation building automation power supply and distribution system,and sets up the specific function index and performance index.Through the comparison,the PLC controller is chosen as the control core,and the building automation supply and distribution platform is built by using the transducer,sensor and other devices.After that,the program of upper computer and lower computer is programmed,and the method of using fuzzy-PID compound control algorithm to control the temperature of air conditioner is put forward,which improves the speed and accuracy of control.Finally,through the host computer program to control the PLC and other equipment,the power supply and distribution of the building are monitored and adjusted,which proves the effectiveness and reliability of the system.
