基于通用数据采集器的温湿度控制系统的研究

The Study of Temperature and Humidity Control System Based on the Current Data Gather

通用数据采集器是基于串行接口方式的单片机通用数据采集系统,该系统以AT89C52单片机为核心,从数据的采集、存储与上位机的通信到数据的显示、打印输出全部采用串行接口器件,从而降低了布线密度,提高了系统可靠性。对库房温湿度进行监测,监测数据送中央控制室处理管理,能随时显示实时数据及趋势图,可自行设定、修改报警温度湿度值,现声测量值达到或超出报警设定值时,中央站可实现声光报警及打印。

The current data gather, a system based on serial interface mode, uses AT89C52 SCM as the core and uses serial interfaceapparatus from data collection, storage with the communication computer to data display and printing output, which can reduce lineddensity and advance reliability of the system. By measuring temperature and humidity and operating them in the center control room, thecurrent data and picture can be displayed at any moment, while the alarm temperature and humidity value can be set and adjustedautomatically. When the current measure reaches or exceeds the alarm value, the center control room gives an alarm by sound, light anda simultaneous printout.
