基于Labwinidows/CVI的北斗短报文上位机设计

目前，国外大多数采用GPS通信相对比北斗通信精度更加准确，为了能够提高北斗的大大推广与使用，北斗短报文通信在国内展开一系列的应用。北斗在国内的优势主要体现在方方面面。例如，北斗短报文通信在生活中，军用方面等起着不可替代的作用。通信抄表中，海上船员健康监测中，泥石流监测系统中。1]根据北斗短报文的广泛应用，分析北斗短报文通信的基本性能，设计了基于Labwindows/CVI的上位机北斗短报文通信软件，软件与系统硬件的传输由Visual C++开发的串口通信调用RS232接口驱动程序完成。进行完成北斗短报文的通信，能够完成自检信息和IC地址的检测，根据用户的操作可以每间隔60秒进行一次接收与发送通信。最终通过测试顺利完成了基于Labwindows/CVI的上位机北斗短报文通信。

Design of Beidou short message upper computer based on Labwinidows/CVI

In order to make Beidou communication widely used , the upper computer software of Beidou short message is designed .Under the development platform of Labwindows/CVI software, a set of interactive interface for man-machine was designed, and the communication of Beidou short message was successfully realized through code realization and serial communication function library. This paper mainly introduces the communication function of Beidou short message using multi-thread, serial communication and other key technologies, and gives the result of functional test. The content of Beidou communication is well received and sent, and the software performance of the upper computer is stable, which meets the actual requirements of Beidou short message communication in practice.
