摘要
传统数据采集系统因其上下位机采用串口连接致使测量人员移动范围与操作灵活性降低,基于此,该文设计一种基于手持平台的蓝牙数据采集系统,以实现采集过程中上下位机的无绳分离,达到无线采集的目的。系统采用蓝牙通讯协议作为通讯方案取代传统的有线串口,以时下应用广泛的Android操作系统移动终端作为上位机,并在该终端设计系统软件,实现移动、便携地进行数据采集,并将接收到的有效数据以文件方式存储。在实际工作环境下对该系统进行测试,实践证明该无线采集系统能稳定、有效地采集数据,实现测量数据无线传输。
Using serial connection in traditional track inspection instrument reduces the range of movement of surveyor and operational flexibility ,designed a handheld platform based on Bluetooth data acquisition system to achieve sepa- ration of the Upper and Lower host computer and the microcontroller and reach the purpose of wireless acquisition. The system uses Bluetooth communication technology to replace traditional wired serial mode,use mobile terminal with Android operating system which was widely used as host computer. Design the system software in the terminal, to achieve portable,mobile data collecting,and the host computer store received data in files.Test the system under actual working environment.Practice has proved that the wireless acquisition system collects data steadily,effectively and achieve wireless transmission of data.
