地震台站无线远程监控及3G备用信道方案实现

THE REALIZATION OF THE SEISMIC STATION'S WIRELESS REMOTE MONITORING AND 3G BACKUP CHANNEL SCHEME

介绍了一稳定可靠的地震台站无线远程监控及3G备用信道方案的实现,其是基于GSM(全球移动通信系统)网络3G(第三代移动通信技术)和SMS(短信业务)的方案。当有线信道出现故障时,中心人员可通过SMS(短信业务)指令对其控制切换并启动无线备用信道,当有线信道恢复后,通过指令关闭无线信道并切换至有线信道进行地震数据传输。具有通过3G无线传输测震数据的功能。

This paper introduces the realization of the seismic station’s stable and reliable wireless remote monitoring and 3G backup channel scheme, which is based on GSM （ Global System for mobile communication） , 3G （ third generation mobile communication technology） and SMS （ short message service） . When the wire channel has failure, center staff can control the switch and start the wireless backup channel through the SMS （short message service） instruction. When the wire channel recovery, we can turn off the wireless channel and switch to wire channel which transmit the seismic data.
