摘　　要：针对具有双泵结构的汽车变速器液压阀板,在进行测试验证过程中,需分别独立控制双泵供油,提出了一种通过伺服电机驱动双泵,上位机采用LABVIEW平台开发,并通过相应的硬件设备实时采集控制电流、压力信号的电机控制和数据采集系统。该系统采用工控机、CAN卡、NI数据采集卡、SINAMICS S120组成硬件结构,通过设计上位机软件实现对伺服电机控制、多种信号采集功能,并重点介绍了上位机软件和实现方式,经现有台架改造和测试,该系统能够实现伺服电机转速控制和信号采集功能,能够满足液压阀板测试要求。For the hydraulic valve plate of automobile transmission with dual pump structure, it is necessary to control the oil supply of dual pumps independently in the process of test and verification. A motor control and data acquisition system is proposed, in which the dual pumps are driven by servo motor, the upper computer is developed by Lab VIEW platform, and the control current and pressure signals are collected and controlled in real time through the corresponding hardware equipment. The hardware structure of the system is composed of industrial control computer, can card, Ni data acquisition card and SINAMICS S120. The upper computer software is designed to realize the servo motor control and various signal acquisition functions, and the upper computer software and implementation mode are mainly introduced. After the existing bench transformation and testing, the system can realize the servo motor speed control and signal acquisition functions, and can meet the test requirements of hydraulic valve plate.
