计价器的研究与实现

Research and Implementation of the Meter

本文研究的电子计价器主要由轮胎传感器、计数器、扫描、里程显示、计价数据显示等模块构成。根据功能需求,通过轮胎传感器将脉冲信号传递到各计数器,来实现针对不同行驶里程数、不同运营时间段区分计价等功能。同时为了体现电子计价器的实用性,规定在红灯等待期间内计价功能暂时中止直至绿灯亮起车辆启动。在QuartusⅡ环境下对电子计价器进行模拟,验证了测试数据的准确性和实用性。

The electronic meter studied in this paper is mainly composed of tire sensor,counter,scanning,mileage display,pricing data display and so on.According to the function requirement,the pulse signal is transmitted to the counter through the tire sensor to realize the function of differentiating the pricing according to the different mileage and different operation period.At the same time,in order to reflect the practicability of the electronic meter,the pricing function is temporarily suspended during the red light waiting period until the vehicle starts on the green light.Finally,the electronic meter is simulated in the environment of QuartusⅡ,which verifies the accuracy and practicability of the test data.
