本文介绍了用8031单片机实现的分布式粮库温度、湿度巡回检测控制系统,该系统利用长线多机通讯原理,成功地使1台主机与64台分机在1公里的范围内进行通讯,并通过软件校正的方法,提高了系统的测量精度。
This paper introduces the distributed grain storage temperature and humidity tour detection control system realized by 8031 single chip microcomputer. The system uses the principle of long-line multi-machine communication to successfully communicate and pass a host computer and 64 extensions within a range of 1 km Software calibration method to improve the measurement accuracy of the system.
