摘　　要：地质环境监测仪器在实际应用中应具有较为严格的仪器属性,包括耐高低温性、密封性、耐腐蚀性、低功耗等。而无公网覆盖地区多为高寒高海拔地区,仪器长期暴露在较为恶劣的地质环境中。因此,及时、稳定的数据通信传输技术是获取水文地质参数、确保地下水动态监测系统稳定运行的关键。目前,地下水动态远程监测技术多采用GSM短信格式进行监测数据的传输,但是该方式在野外应用中非常受限。为使地下水参数监测不受无线公共网络覆盖区域的限制,利用北斗卫星的定位与短报文技术,研究了一种可利用北斗卫星进行数据传输的通信仪器。经过大量的室内调试及野外稳定性试验,证明了基于北斗卫星开发的地下水动态监测通信控制终端,数据传输稳定,仪器功耗低,防风、防沙、防潮性能良好。该研究解决了无手机信号地区地下水监测数据的传输障碍,实现了多方式的地下水监测通信。In practical applications,the geological environmental monitoring instruments should have more stringent instrument properties,their resistance to high and low temperature,sealing,corrosion resistance and low power consumption,etc.,are all have higher requirements.While the areas whitout public network coverage are mostly alpine high-altitude areas,the instruments are exposed to relatively harsh geological conditions for a long time.The timely and stable data communication transmission technology is the key technology to ensure stable operation of groundwater dynamic monitoring systems.At present,GSM short message format is mostly used in the groundwater dynamic remote monitoring technology,but this approach is extremely limited in field applications.For obtaining groundwater monitoring parameters not affected by the limitation of public wireless network coverage area,the Beidou satellite positioning and short message technology is adopted,and a kind of data transmission communication apparatus using Beidou satellite is researched.After a large number of indoor debugging and field stability tests,it is proved that the control terminal of groundwater dynamic monitoring and communication developed based on Beidou satellite communication features stable data transmission,low power consumption,good resistance of wind,sand and moisture.It solves the transmission obstacle of groundwater monitoring data in the area without mobile phone signal,and realizes multi-mode groundwater monitoring communication.
