|
摘要
煤矿无线传输地震勘探系统不仅高效便捷地采集和处理数据,还可以在线监测地震数据和地震仪的工作状态,大大简化了现场施工过程。基于目前煤矿地震勘探仪的无线传输速率较慢且实时回传效果不佳这一问题,提出了一种多通道无线传输系统的新思路,在总结了地震勘探无线传输系统的基本原理后,详细介绍了单通道和多通道无线传输系统的数据无线传输过程和系统工作流程,最后进行了单通道和多通道的对比测试试验,试验结果表明多通道较之单通道其无线传输速率成倍提升,且干扰和误码率降低不少。
The coal mine wireless transmission seismic exploration system not only collects and processes data efficiently and conveniently,but also monitors the working status of seismic data and seismographs online,which greatly simplifies the on-site construction process.Based on the current problem that the wireless transmission rate of coal mine seismic exploration instrument is slow and the real-time backhaul effect is not good,a new idea of multi-channel wireless transmission system is proposed.After summarizing the basic principles of seismic exploration wireless transmission system,detailed The data wireless transmission process and system workflow of single-channel and multi-channel wireless transmission systems are introduced.Finally,single-channel and multi-channel comparison test tests are carried out.The test results show that the multi-channel wireless transmission rate is doubled compared with the single channel.And the interference and bit error rate are reduced a lot.
