摘　　要：由于液压系统构成元件状态参数的影响,导致液压阀门故障诊断的准确性较低。为此,本文提出基于组态技术的液压阀门故障智能诊断系统设计研究。首先,将具备高传输效率和信号转换功能的LTD-ZA210作为系统的串行外设接口(Serial Peripheral Interface,SPI)控制器,将包含数字电源和模拟电源的综合型电源作为系统的电源模块。其次,将液压系统中分流流速、集流流速转换为对应的测压力值和流量值,利用组态技术划分周期。最后,通过分析支持度约束下阀门状态参数与运行期望之间的关系,实现对其故障的诊断。测试结果表明,设计系统对半失效以及完全失效故障的诊断准确率可以达到95.00%以上。Due to the influence of the state parameters of the components of the hydraulic system, the accuracy of hydraulic valve fault diagnosis is low. Therefore, this paper presents the design and research of hydraulic valve fault intelligent diagnosis system based on configuration technology. Firstly, LTD-ZA210 with high transmission efficiency and signal conversion function is used as the Serial Peripheral Interface(SPI) controller of the system, and the integrated power supply including digital power supply and analog power supply is used as the power module of the system. Secondly, the diversion flow rate and collection flow rate in the hydraulic system are converted into the corresponding measured pressure value and flow value, and the cycle is divided by configuration technology. Finally, the relationship between valve state parameters and operation expectation under support constraints is analyzed to realize its fault diagnosis. The test results show that the diagnostic accuracy of the designed system for semi failure and complete failure can reach more than 95.00%.
