粮情检测系统中的粮温检测点布置国家已有标准,我们在使用过程中发现矩阵布线方法存在检测盲区。为此,我们提出:在不改变矩阵布线方法和增加检测点的前提下,开发粮情检测系统智能分析功能,以完善矩阵布线方法。 1 基本情况 1.1 粮情测控系统组成 计算机、测控分机、分线器(采集器)、测温电缆。 1.2 温度传感器类型 热敏电阻型MF53—1。 Grain detection system in the grain temperature detection point layout of the country has a standard, we found that the use of matrix routing method has blind detection zone. For this reason, we propose to develop the intelligent analysis function of grain detection system without changing the matrix routing method and increasing the inspection points, so as to perfect the matrix routing method. 1 The basic situation 1.1 Food situation measurement and control system consists of computer, control extension, splitter (collector), temperature cable. 1.2 Temperature Sensor Type Thermistor type MF53-1.
