摘要
为了保证地震观测台站的正常运行,解决当前台站动行观测系统存在的抗干扰性不高、观测结果与实际结果不一致,资源利用不足及工作效率不高等问题,利用多种技术相结合的方式,设计一套集设备管理、地震观测无人值守台站信息采集、信息通讯、信息管理与应用为一体的地震观测无人值守台站信息智能化观测系统。考虑到地震观测台站工作任务的特殊性,分析台站运行状态观测系统应具备的功能;为了实现实时监测、及时抢修以及远程操控,采用具有双通道可切换的12 V稳压直流电源和UPS作为观测系统供电设备,采用有线、无线双线路备份的方式集成网络通信系统,并实现人机交互设计;在此基础上,重点设计包括用户管理、值班工作管理、台站设备管理、台站运行状态观测、故障预警以及故障派单及抢修等系统软件部分,完成系统设计。性能测试结果表明,设计系统能够在网络中断时继续保持信息传输连续率,工作效率较高,具有较强的抗干扰性、稳定性和可靠性,同时没有造成较大的资源浪费。
To ensure the normal operation of seismic observation stations and solve the problems existing in the current system, such as the weak observation anti-interference ability, the inconsistency between the observation and actual results, the inefficient utilization of resources, and the inadequate working efficiency, using the combination of various techniques, an intelligent seismic observation system of unattended station information is designed. The system integrates equipment management, information collection, information communication, information management, and application. Considering the particularity of the working task of seismic observation stations, the required functions of the observation system are analyzed. To realize real-time monitoring, timely repair, and remote control, a 12 V stabilized DC power supply and a UPS with two channels are used as the power supply equipment of the observation system. A network communication system is integrated by adopting a wired and wireless dual-line backup mode, and a man-machine interaction design is realized. On this basis, the system software, including user management, on-duty work management, station equipment management, station operation state observation, fault early warning, and fault emergency repair are mainly designed. The performance test results show that the design system can maintain a continuous rate of information transmission when the network is interrupted, and the work efficiency is high. It has a strong anti-interference ability, stability, and reliability, and does not cause a large waste of resources.
