基于单片机的出租车计价器检定装置的设计

Based on MCU Taximeter Verification Device of Design

为解决出租车计价器检定装置布线繁琐和检测效率不高的问题,提出一种以AT89C52单片机为核心的出租车计价器检定装置的设计方法。以霍尔传感器作为检测元件并产生脉冲信号,通过无线模块将记录的脉冲传送到与微处理器相连的无线接收模块,并与出租车计价器记录的脉冲个数进行比对,检测出租车计价器是否符合计价标准。系统还对检测台的设计进行了改进,使其在检测过程中更加快捷方便,提高检测台的使用寿命和检测效率。实验测试结果表明,该设计符合出租车计价器整车检定装置的技术指标要求,系统操作方便,检测精度较高,稳定性较好,能满足实际测试的需要。

In order to solve wiring cumbersome and detection＇s low efficiency of the taxi meter verification equipment, we introduce a design method for the taxi meter＇s calibration device whose core is AT89C51 single- chip microcomputer. Hall sensor as its detecting element produces the pulse signal which is transmitted to the wireless receiving module connected to wireless module of the microprocessor. Then it compares the pulse number from taxi＇s meter records to check the taxi meter according with charge standards or not. Moreover, the system improves the design of the test bench to make it be more quick and convenient in the process of detection. It also improves the service life as well as detection efficiency of the test bench. Through the experiment testing in accordance with the technical indicators of the meter taxi vehicle prover requirements, the system Convenient operation has some advantages, such as convenient high accuracy, and good stability, which can satisfy the need of actual test.
