摘要
地震科学探测台阵是开展地震学综合研究的大型野外观测系统,可根据观测目的布置在一定区域内进行连续观测。其特点是数量大、分布广,台站工作状况易受外部环境的影响。实际工作中迫切需要掌握流动地震仪的工作状态,而人工巡台工作量大,时效性不能保证。流动地震仪器工作状态的监控对于野外流动观测具有重要意义。我们采用虚拟网络(VPN)技术,通过无线(CDMA/GPRS)通讯方式组成局域网,实现了科学探测台阵总控中心-流动监控中心-观测仪器间的实时通讯,可方便、快速地对大量流动观测台进行实时监控和数据传输,显著提高了远程仪器维护的工作效率,便于提高观测质量。
Seismic Array is a large scale portable seismic observation system to carry out the comprehensive study of Seismology, it can be operated continuously in a certain area according to the observation purposes by a large number of seismometers. Working Environment has a strong impact on its recording quality. It is urgent and significant to monitor the working state of the portable seismometers. Thus, a virtual network (VPN) technology has been adopted. By use of wireless (CDMA/GPRS) network, the real time communication between Control Center, Mobile Monitoring center and portable seismometers has been achieved, by which the real time monitoring and data transmission for a large number portable seismic stations can be realized easily. Then, it results in increasing the efficiency of long range equipment maintenance, and improving the recording quality.
