摘　　要：随着社会的发展、粮食储藏的高度集中,粮食自动化测温已是粮库建设和管理中不可缺少的一部分,但由于粮食测温系统工作的环境存在着特殊性和复杂性以及用户选择时缺乏经验,致使已使用的测温系统,在不同程度上都存在着故障率高、稳定性差、可维护性差等问题。文中介绍一种根据系统电子元器件和非焊接结点等参数与传感器之比计算故障指数,从而分析出系统的故障率、稳定性、可维护性等指标的方法,供研发和使用粮食测温系统者参考。With the development of highly concentration of the Grain storage and the society, automatic grain temperature measurement system is a indispensable part of the building and managing of grain depot, but due to the specialization and complexity of the temperature measurement system's working environment and the user's lacking of experience in cloosing the right one, many problems occur in the current using measurement system such as: high failure rate, low reliability, poor maintainability. The paper introduces a computing way to figure out failure exponent by comparing the ratio of sensor to the parameter of system active devices and non -joint crunode, through which the failure rate, stable ability and maintainability can be analyzed for the reference to the user and developer of grain temperature measurement system.
