该系统以工控机为中央控制器,在仓库的每个库房安排一个微控制器(分机)通过单一信号传输线与库房内所有监测点的数字式传感器相连,采集各点温湿度数据,中央控制机与微控制器以串行通讯方式实现信息传输。采用“一线总线”结构实现粮库多点温湿度检测,为粮食仓储领域提供一种测试准确,性能稳定可靠,线路及系统安装简单,使用和维护方便的粮库温湿度自动监测、分析与控制系统,实现粮情测控的全面优化。
The system uses industrial computer as the central controller and arranges a micro-controller (extension) in each storeroom of the warehouse to connect with digital sensors of all the monitoring points in the warehouse through a single signal transmission line to collect temperature and humidity data of each point. The central controller Communication with the microcontroller to achieve the information transmission. Adopting “one-line bus ” structure to realize multi-point temperature and humidity testing of grain depot, providing an automatic monitoring and analysis of temperature and humidity for the grain storage area with accurate testing, stable and reliable performance, simple installation of circuit and system, convenient use and maintenance And control system, to achieve full optimization of grain measurement and control.
