五轮仪数据采集器的设计

Design of Data Acquisition Instrument of the Five-Wheels

现有五轮仪在车辆试验的数据采集过程中存在着不足 ,为此设计了五轮仪数据采集器 该采集器以 89C5 1单片机为核心 ,采用了虚拟I2 C总线技术 ,体积小 ,功耗低 ,存储量大 ,并实现了与PC机的通讯 该装置具有很强的实用性 ,改善了五轮仪的数据采集过程 。

There exist some faults in the course of data acquisition in the test of vehicle. To remedy the faults, the author designed the data acquisition instrument for the five wheels. It is based on 89C51 single chip microprocessor and employs the Virtual I 2 Bus technology. It has features of small size, low power dissipation, large memory capacity and the ability of communication with PC. This system has strong practicability, improves the course of data acquisition and provides the access for the analysis of acquired data.
