摘要
针对粮库温湿度检测实际情况,设计了基于CAN总线的粮库温湿度监控系统,详细介绍了其硬件和软件的设计。该系统能自动监视粮库温湿度变化,实时与预先设定的温湿度参数值进行比较,并驱动相关驱动设备,使粮库温湿度保持在一定的范围内。远程监控系统使用了CAN总线技术,增强了系统的可靠性。该系统已成功应用于粮库温湿度监控。从实际应用情况来看,该系统不仅在信息传输的安全性、准确性和实时性方面均能满足控制的要求,而且具有很高的可靠性。
Aiming to the fact of inspection and measurement of temperature and humidity for a grain depot,this intelligence system of distant measurement and contro1 of temperature and humidity for the grain depot is designed,and the hardware and software of the system is introduced in detail.The system can automatically supervise changes of temperature and humidity for the grain depot,compare with the preset parameter of temperature and humidity,and drive the correlative power equipment in order to keep temperature and humidity in stated ranges.The CAN bus technology is used in the distant measurement and control system,which improves the reliability of system.The system has been already applied successfully.From the work condition,the system can meet the requirements of the measurement and contro1 in security,accuracy,real-time capacity and has high reliability.
