东北地区野外地质工作地点分散,通讯不畅;进入陌生区危险性大;流动性大,管理不便.将北斗卫星技术引入东北地区野外地质调查,建立基于北斗卫星系统的野外—驻地—中心三级网络,不仅可以实现无人区和无通讯信号工作区野外地质调查人员与外界的通讯,还可以进行有策略的多路线业务互动.存放于北斗卫星服务系统中的安全预警预案数据库,可以有针对性地对有安全诉求的终端所在区域推送安全须知和突发事件处置方案.野外作业人员通过北斗卫星蓝牙接入模块,在通讯信号覆盖不到的区域也可以第一时间获取到重要的通知、公告等信息.系统在东北地区的示范应用效果良好.%There are three main disadvantages of geological survey in the northeast China as below; firstly, It's very hard to communicate each other when the people worked in dispersed locations; secondly, high fluidity was difficult to manage and arrange; thirdly, it's very dangerous when entering unfamiliar areas. Beidou satellite technology made all these problems solved in a certain extent. It's not only making people communicate each other by text message without mobile phone, but also can take interactive multi-route business strategy. The security warning plan database stored in the Beidou satellite service system can be targeted to the terminal area of security demands by pushing safety instructions and emergency disposal program. Workers through Beidou satellite module can get all the information, bulletin and messages timely they need in the area that communication signals do not cover. The application of this system effected very well in northeast China.
