摘　　要：该文介绍了利用传统的短波单边带电台通过抗干扰数据终端（Ｍｏｄｅｍ）和计算机相结合，将计算机中的图文信息（任意文件格式）进行长距离传输的实现方法。并对该系统实现的图文信息无失真压缩、报文加密／解密、短波信号调制、高端通信协议等关键技术进行介绍。该系统可应用于林业、石油、矿山、地质等领域，尤其适合于西北边远地区。This paper introduces the method of transporting any graphics and text information at long distance bycombining the traditional shortwave unilateral-band broadcasting-station with computer through anti-interfere data- modem. Morover,we present the crucial technologies about no-distortion compressing graphic and text information,message Encrypt and cryptanalysis, shortwave-signal modulation and high-level communication protocol in this system. The system can be used for the domain of forestry, petroleum, mine, geology and so on, especially fit for the west-north remote regions.
