Data Acquisition And Control System Design

Along with the development of computer science and technology, the measurement data technology's all-round development, data information collection technology, the sensor technology and communication technology, remote control technology and network technology rapid development, people on the nature of non-electric quantity gathering demanded increasingly through electronic equipment achieved, data acquisition device used more widely.Traditional data acquisition and processing work has been far can not meet the need of the actual users in electronic equipment, highly integrated modern, information and data for a central treatment has become widely accepted by all the new mode, thus appeared the data acquisition system, communication system, control system, and the data processing system and constitute the data acquisition and remote control system. This system will original distributed data acquisition and processing of scattered data, into a centralized processing, after the collection of unified control. Because the data processing part of the control algorithm introduced more, thus achieved the intelligent control of equipment.Remote data acquisition and control system is the main basis for temperature and humidity changes of intelligent air conditioning control part of the system. Through the temperature sensor on indoor temperature and humidity are collected, SCM simple processing by standard serial interface, after supreme place machine, then transmitted by PC after a comprehensive analysis, down a machine a controlled air conditioner motor start-stop control signals, thus by next place machine control corresponding motor start or end. Therefore, the remote data acquisition and control system design, is a very has theoretical significance and application prospects of important projects.
