汽车零部件试验测控平台示波模块的设计

Design of Digital Oscilloscope Module in Measurement & Control Platform for Automobile Components Test

针对传统仪器在汽车零部件性能测试中存在的不足,将测控平台思想和技术运用到汽车零部件性能测试中;结合面向汽车零部件试验的通用测控平台中数字示波模块的实现,探讨了在Visual C软件开发环境下数字示波模块的设计方法;通过示波环境设计、数据读取、波形显示与放大、动态播放速度控制和多个信号波形比较的编程过程和技巧,设计出的数字示波系统具有很强的移植性和可扩展性,并在车辆液力减振器试验测控平台的实例中验证了该设计方法的有效性。

Facing the disadvantages of the traditional instrumcnt in the field of the automobile performance test.the conception and technology of measurement ＆ control platform was introduced to it.During the imptempentation of digital oscilloscope module applied to general measurement＆ control platform for nutuomobilc components test-oricnted.the design method of digital oscilloscope module base on Visual C has been discussed.With the programming skills and proccssing methods of oscilloscope environment design.data acquistion.waveform displaying and amplifying, velocity control of dynamic playback and multi--signal waveform comparlson, the digital oscilloscope syslem has enough exlensible capability, and the efficiency of such design method was validated by the vehicle hydraulic shock absorber test platform.
