Design of Computer Application Building Automation Control System

摘要

The object of this research is building automation control system and to design the system by means of thecomputer application. First, I analyze the operating principle of the automatic monitored control system based on thecomputer technology, and I find that with the help of Ethernet switching engineering we can solve the problem about highnetwork load and transmission delay of traditional building automation control system. At the same time, I design theoverall structure of the automatic monitored control system. Then I learn the hardware control system and the implementationof the software, and the mainly representative object is the central air-conditioning control system. As the corecomponent of the control system, PLC’s hardware and transducer are chosen. And I design the process of software control,data acquisition, communication device and other modules. Meanwhile, I finish the design of the procedure of PLCmaster control module and realize the software monitoring and control with the host computer software. Finally, I explorethe remote monitoring software based on internet, and improve some problem like the spread of information during themonitoring in the past and develop the auxiliary function of short message reminder with the end of the integrated structure,idea and the structure based on the computer application and the design of the key part.
