粮情测控系统是安全储粮的工具,它的可靠与否,直接关系到储粮的安全,因此使用中必须做好日常维护工作,确保系统运行正常,检测数据准确。由于计算机粮情测控系统的工作环境较恶劣,使用环境中存在磷化氢等强腐蚀性气体以及粉尘、水汽等,且通信线路较长,易受各种电磁干扰,可靠性受 Grain condition monitoring and control system is a tool for storing grain safely. Whether it is reliable or not is directly related to the safety of grain storage. Therefore, routine maintenance work must be done during use to ensure that the system runs normally and the detection data is accurate. Due to the harsh working environment of the computer food control system, there are strong corrosive gases such as phosphine and dust, water vapor and the like in the use environment, and the communication lines are long and susceptible to various electromagnetic interferences. The reliability is affected by
