摘　　要：为有效改善液压加载试验台的自动化水平和控制精度,提出一种状态监测系统,主控器采用AT89S52单片机,通信方案选取CAN总线方式。以压力、流量和温度等参数为测控目标,对系统中的主控模块、数据采集模块和通信模块等关键功能模块进行了设计与研究。通过对液压阀加载试验的流程设计、参数测试和结果分析可知,在模糊控制与反馈调节条件下,该系统能够实现较高的液压监测精度和响应效率。In order to effectively improve the automation level and control accuracy of the hydraulic loading test bench,a state monitoring system is proposed.The main controller is AT89S52 single chip microcomputer,and the communication scheme is CAN bus.The main control module,data acquisition module and communication module of the system are designed and studied with the parameters of pressure,flow and temperature as the measurement and control objectives.Through the process design,parameter testing and result analysis of the hydraulic valve loading test,it can be seen that the system can achieve high hydraulic monitoring accuracy and response efficiency under the conditions of fuzzy control and feedback regulation.
