停车计时收费系统的研发

文章介绍了一种基于蓝牙技术的停车计时收费系统。系统主要由五个部分组成：蓝牙模块、数据采集模块、数码管驱动显示模块、单片机控制模块和手机客户端。系统一旦检测到有车辆入库或离库单片机就会将车位的变化信息发送给手机客户端，手机客户端根据此信息对车辆进行停车计时和计费，同时将相关信息显示在数码管上．手机客户还可实现查询车位的使用情况。最后文章给出了系统的测试结果。

Development of Parking Timing and Charging System

A parking timing and charging system based on Bluetooth technology is introduced. The system consists of five parts： a Bluetooth module, a data acquisition module, a digital tube driving display module, an MCU control module, and a mobile client. The system will send information about the changes in the carport to the mobile client when a car enters or leaves the carport. The carport starts timing when a car enters and stops timing when the car leaves and the cost is computed and showed on the nixie tube. This paper uses hardware experiments to build the system, to validate the feasibility of the system, and then to provide the test results of the system.
