摘要
随着电子技术的发展,智能化测试设备已成为提高汽车发动机研发水平和改善质量的重要手段。结合单片机采集数据灵活方便和PC机处理数据能力强,测试结果易于输出和保存的特点,设计实现了发动机多通道参数测试系统,利用C8051F系列单片机完成对多通道参数的采集、预处理以及输出。采用VB语言在PC机上创建一个界面,用于显示和保存测量结果,并进行了实际验证试验。结果表明,本系统具有使用方便,测量精度高,数据处理能力强及可靠性好等特点,有一定的实用价值。
With the development of electronic technology, intelligent tester has become an important method to develop the level and improve the quality of automobile engine. This paper combines single-chip microcomputer which is flexible in collecting data with PC which has a strong ability in data processing and easy to save the results, designs the muhi-channel data collecting system with C8051F serial CPU to collect processing and transmit data. In displaying method, the system designs an interface with VB to display and save the data. The achievement of multi-channel data collecting system verifies the designing target. The system has many advantages such as easy to use, high precision measurement, good reliability and has certain practical values.
