摘　　要：介绍了一种基于3G(第三代移动通信技术)和SMS(短信业务)的无线数据传输测震台监控仪的工作原理、设计和实现。可实现对相关设备进行断电、上电、重启和备用设备切换等控制;具有通过网口和串口监控数据采集器工作状态的功能;具有通过3G无线传输测震数据的功能。Quickly recovering the seismic signals channel or solving problems with seismic station equipment is a major challenge once they are damaged or experience sudden failure. In our study, we designed and constructed wireless data transmitting and monitoring equipment for seismic sta- tions based on the global system for mobile communication（GSM）, third generation mobile com- munication technology（3G） and short message service（SMS}. This equipment can control（shut down,switch on, restart, and enable the backup device）remote equipment easily, monitor the earthquake data acquisition system （EDAS） by the serial port and network,and transmit the seis- mic data by 3G. The hardware is composed of a core interfacing circuit board and a driving circuit board. The core circuit board includes one LAN port, two COM ports,and a number of I/O inter- faces. The working status of the EDAS at a local seismic station is real-time monitored through the LAN port and COM port. When abnormal data is outputted from the EDAS,the data output stops or is unable to be recognized. Abnormal information of the EDAS is sent to the earthquake monitoring center as short messages,and the center staff is able to make a judgment and take the correct action according to the messages. We designed two CPUs on the core circuit board, one a P89c668 and the other an STC12C5A60S2. The device can make data exchanges with the EDAS- 24IP through the LAN chip. Meanwhile, P89c668 can monitor the real-time data flow of the EDAS-24IP,and analyze the correctness of the seismic data flow of the EDAS-24IP as well. In order to store parameter data, we used an electrically erasable programmable read-only memory （EEPROM}chip known as AT24c08. The driving circuit board is composed of an isolated driving circuit（such as HC4066 and 6N173）and various relays. A double AC-DC switching power supply, designed for use as backup, begins to work when the main supply is in failure. The design and realization of this equipment can solve some common problems in
