便携式PPM性能测试装置的设计

Performance test device design of portable PPM

该测试装置是一种用于柱塞泵与柱塞马达(Piston Pump&Motor)液压试验台的便携式性能测试装置。把该装置与HEDLAND公司生产的Flo-tech系列的涡轮流量传感器连接,可以对温度、流量、压力进行测量,并通过上位机软件的数据处理,可以得出被测PPM的性能报告。该装置基于C8051F206单片机,采用CP2102实现了USB的功能,该装置具有精度高、噪声低、抗干扰能力强等特点,经实际使用证明本装置具有很强的市场推广价值。

This test set is a sort of portable device which could be used on Piston Pump ＆ Motor （PPM） hydraulic pressure experiment table. Connected the set with the turbine flow sensor of the series of Flo-tech produced by HEDLAND company, temperature, flux and humidity could be tested. And the performance report of the measured PPM could be gained by the data processing software of PC .This system based on the C8051F206 singlechip and used CP2102 to achieve the function of USB. The structure of hardware and software was gone into particulars. This set has some characteristics such as high precision, low yawp and strong anti-jamming capability. And it is proved that this test set has very strong market generalize value by practice.
