手持设备无线遥控LED可变信息情报板探讨

摘要

探讨手持设备无线遥控LED可变信息情报板技术，通过使用手机上的蓝牙模块发布、控制工程车后部的LED诱导屏信息变化，采用Java编写应用程序输入手机系统，探讨方案实施的可行性。该远程无线通信遥控方法亦可解决城市公路诱导屏、情报板等控制光缆损坏情况下临时发布信号，信号准确、低功耗、无流量费用，且该技术可设置加密匹配，防止盗用。该方法控制方便，构思新颖，可靠准确，绿色节能，安全可靠。%It’ s the article of exploring the handheld device controlling the variable LED information board remotely with wireless signal. This technology display the information on the upper control truck high-end LED screen change through the use of mobile phones with Bluetooth module,. The controlling application is written by Java which runs on Android system to provide the feasibility of the scheme. This technology can also solve the problem for urban highway guidance screen when its cable is damaged The signal need no flow cost with less mistakes and it’s low power consumption. As well, it needs to be authenticated for pro-tecting used by others. This method is easy to control. The design is novel, reliable, accurate, green, energy saving and security.
