摘　　要：北斗短报文功能在国防、民生和应急救援等领域都具有很强的应用价值。利用北斗短报文通信费用低廉的优点,设计了一款可进行远程图像传输的系统。针对北斗短报文通信的局限性,提出了相应的数据传输机制以保证远程数据传输的可靠性与有效性,并对系统功能进行了验证。测试结果表明,系统能够较快地完成图像数据传输的功能。The short message function of Beidou has strong application value in the fields of national defense, people’s livelihood and emergency rescue. In this paper, a remote image transmission system is designed by taking advantage of the low cost of Beidou short message communication. In view of the limitation of Beidou short message communication, the corresponding data transmission mechanism is put forward to ensure reliable and effective remote data transmission, and the system function is verified by tests. The test results show that the system can quickly complete the image data transmission.
