基于蓝牙串口适配器的GPS接收机与AutoCAD的实时无线通信

Real-Time Wireless Communication Between GPS Receiver and Auto CAD Based on Bluetooth Series Adapter

着重介绍了在GPS接收机的RS-232串行通信接口加装蓝牙,利用Win8平板电脑的蓝牙与之建立无线通信网络,通过Auto CAD VBA开发工具编写通信程序,采用异步串行通讯方式实时接收GPS串口数据,经数据转换后供测图人员使用。从而去除连接线缆的限制,实现了移动作业,提高了工作效率。

This paper emphasizes how to use Bluetooth in Win8 Tablet PC and Bluetooth installed in RS -232 serial communication interface of GPS receiver to establish a wireless communication network. By the use of VBA to program serial communication and the use of asynchronous serial communication way to achieve real-time GPS serial datareceiving, the converted data can be offered to the mapping technicians. Without the restriction of connecting line, this method can realize the mobile operation and improve the work efficiency.
