一、序言微机应用在液压泵试验台上进行参数信号采集、数据处理。目的在于提高测试精度和试验效率,从而提高液压测试技术水平。微机已在信号的采集方面开始应用,存在的问题有:传感器与微机间的输出和输入的匹配问题以及由于专业性的微机配套附件不齐而涉及到的微机的选型问题。选型时要考虑到微机的功能,附件是否齐全;包括A/D转换板,I/O接口板,打印机,绘图仪及主机内是否还
First, the introduction of computer applications in the hydraulic pump test bench for signal acquisition, data processing. The purpose is to improve the test accuracy and test efficiency, thereby enhancing the level of hydraulic test technology. Microcomputer has been applied in the signal acquisition, the existing problems are: the output of the sensor and the output of the computer and the input matching and due to lack of professional computer-related accessories involved in the selection of computer problems. The selection should take into account the computer’s features, accessories are complete; including A / D converter board, I / O interface board, printer, plotter and the host is also
