新型车速里程表与出租车计价器检定系统的研制

Development of the new-type verification system used to verify speedometer and odometer or taximeter

采用单片机与微型计算机相结合的方案,设计了一种新型车速里程表与出租车计价器检定系统.该系统以微型计算机及由单片机系统构成的检定本机为核心,二者通过RS-232串行接口通信,协同完成多项检定功能.应用结果表明:该系统具有测量精度高、工作可靠、通用性强、使用方便、用户界面友好等优点,可广泛应用于车速里程表及出租车计价器的检定工作.

A new-typed verification system to verify speedometers ＆ odometers or taximeters was designed by means of the combination of a microcomputer and a microcontroller. The microcomputer and the verification unit based on a microcontroller are the core of the verification system. The microcomputer exchanges information with the verification unit through a serial communication interface （RS -232）, and they collaboratively complete many verification functions. The preliminary results showed that the system owns such advantages as high accuracy, high reliability, high universality, conveniency and possessing user-friendly interface and so on. So it can be used for the verification of speedometers and odometers or taximeters.
