一种冷库温度集中监测系统的研制

The Design for A Kind of Temperature Concentration Monitor System of Cold Storage

大多由果农、菜农自建的冷库一般采用悬挂温度计人工观测的方法来监视冷库温度,冷库温度观测很不方便。而由单片机、温度传感器、AD转换器组成温度测量装置,可将其安装在多个冷库的测温点,并挂在RS485总线上,各温度测量装置即可将测量结果通过RS485总线传送到安装在监控室的主机,主机再按一定顺序依次循环显示各测量点的温度,从而可实现集中检测的目的。

Most cold storage built by the fruit, vegetable producers monitored the temperature cold storage by suspending thermometer manual observation method, which was very inconvenience. While the temperature measuring device composed of single chip microcomputer, tempera- ture sensor, AD converter installing in many temperature measuring points and then hanged in the RS485 bus. The measured results from each temperature measurement device delivered to the host of supervision room through the RS485 bus. The host displayed the temperature of each measuring points in order to achieve the aim of concentrated examination.
