Design for the System of Speedometer Testing Set

摘要

The system can produce the drive pulse signal of speedometer and make the speedometer display the speed value while substituting for the velocity sensor based on the principle of speedometer. It implements static detecting of speedometer. Data communication and microcomputer communication constitute a complete speedometer testing system at the same time. The system implements successfully the interface function by PowerBuilder receiving data. With serial interface communication, PowerBuilder receives the data sending by SCM, and stores it into the database by data processing. Its performance satisfies completely user's demands. Now it has come into the markets, also including portable pattern. It is very popular for users.
