摘要
利用蓝牙移动通信终端和蓝牙模块之间低功耗、低成本的无线通信方式,设计一个基于Android蓝牙通信的交通控制系统。通过在Android系统的手机安装上编好的App,然后与交通信号机里面的蓝牙模块配对来对交通灯进行控制。使用Android系统编写上位机软件,实现了Android上位机与ARM下位机的串口通信,并对交通灯控制系统进行现场控制。实验结果表明,信号稳定,数据传递正确。
A traffic control system based on Android Bluetooth communication was designed by using low power consump- tion and low cost wireless communication between Bluetooth mobile communication terminal and Bluetooth module. The pro- grammed APP is installed on Android mobile phone and then paired with the Bluetooth module inside the traffic signal controller to control the traffic light. The PC software was compiled by means of Android system to realize the serial communication be- tween Android PC and ARM slave computer. The field control experiment for the traffic light control system was performed. The results show that its signal is stable and its data transmission is correct.
