| In recent years, BeiDou Navigation Satellite System develops more rapidly, performances more stable, is used more widely. Such as GPS and other global navigation system, it can obtain the time and position information, in addition, the main feature is the short message communication service. As long as the system is covered in the area, its end users will be able to carry out two-way communication.According to the innovative features of the communication and navigation of the BeiDou Navigation Satellite System, and the current BeiDou industrial application status in the market, based on researching the hardware circuit of Beidou beacon terminal that fuses the Beidou satellite positioning, the Beidou short message communication, Bluetooth and other technology, designing and completing the application software of its operation, including:(1) discussing the development of the Beidou satellite navigation system, and Beidou beacon terminal research significance; (2) analysizing the overall design scheme, studing the hardware architecture of embedded system based on ARM and Beidou Positioning, communication, Bluetooth communication, speech synthesis and other related technologies; (3) completing the design of Beidou beacon terminal communication software, it is divided into μC/OS-Ⅱ embedded operating system underlying application software and client application software based on Android mobile phone. The bottom layer application software is realized with the system hardware, the mobile client application software configures and operates the Beidou beacon terminal using bluetooth with the visual interface and powerful text editing function of the phone.In the end, the article has carried on the debugging and the testing to the Beidou beacon terminal, after analyzing, the results show that the design of the Beidou beacon terminal communication software can run smoothly, and has the advantages of simple operation, stable communication and so on. |
