一、问题的提出 目前V带测速试验机的测速系统大多采用电子管或晶体管产品.不仅功能单一.不易维修.测量误差较大.而且不能进行现场实测,鉴于以上原因,本文介绍一种新型的、高可靠性的用单片机控制的V带测速试验机的测速系统。该系统由信号测量、数据采集、预处理、信号分析等部分组成。由于充分利用了8089单片机的功能.因而系统构造简单,功能扩展能力强.用于推广应用于现场机械设备的信号采集和分析。
First, the issue put forward V belt speed testing machine speed test system are mostly used tube or transistor products. Not only a single function. Difficult to repair. Measurement error is large. And can not be measured on the spot, in view of the above reasons, this article describes a new, High Reliability Velocity Measurement System of V Belt Speed Tester Controlled by Single Chip Microcomputer. The system consists of signal measurement, data acquisition, preprocessing, signal analysis and other components. Due to take full advantage of the function of the 8089 single-chip microcomputer, the system is simple in structure and strong in function expansion, which is used for signal acquisition and analysis of the field machinery and equipment.
