【摘要】设计了一种以测试碾米机、粉碎机为主的农产品加工机械性能测试系统。该测试系统以机械装置为
基础,以工业控制计算机为上位机,以 PLC 为主控单元,以组态王 6 5 为上位工控机软件开发平台,对测试系统各
路传感器数据进行实时采集和显示,并对采集的数据进行分析、处理、显示、输出和保存,从而准确地测试出被测机
械的主要技术性能参数。运行试验与计量测试表明,该系统测试的质量、功率、温度参数的精度为 0 38 %、1 0 %、
± 0 9 ℃,均高2 于2系统设计要求的 02 5 2%、1 5 %、± 1 ℃,系统运行稳定,各项控制功能均能可靠实现。

Abstract
A performance measuring system of agricultural products processing machine for testing the
mechanical performance of rice mill and hammer mill was designed. The measuring system was
designed based on mechanical devices , took an industrial puter as puter , PLC as
main control unit and Kingview 6. 5 as software development platform for IPC. It can measure in real
time and display data of transducers of the measuring system. The system can analyze , process ,
display , output and store sampling data to get related main technical performance parameters of the
