SSS-200/300系列震源同步系统有线-无线信号中继设备的研制
|
摘要
在山地、原始森林等复杂施工地区 ,无线电信号受到严重干扰和衰减 ,遥控震源同步系统编、译码器间的无线通信受到严重影响 ,成为制约野外恶劣环境下地震勘探施工进度的重要因素。为此 ,研制成功了一种有线-无线信号中继设备 ,其特点是在复杂的地形、地貌区域施工时 ,译码器均能工作于无线状态。实际应用表明 ,效果良好
In the field operation of seismic crews,the effictive radio communication distance between the encoder and decoder of the remote Seismic Source Synchronizer system may be greatly shortened by obstacles such as mountains and jungles,which is one of the main reasons that decrease the production efficiency of the seismic prospecting in difficult areas.To resolve this problem,a line radio signal exchanger has been developed,with which the decoder can always be operated in wireless mode.The design principle and working procedure of the equipment are introduced,its block diagrams are provided as well.
