Design And Implementation Of Remote Monitoring System For Cable-less Seismograph Based On Beidou And GPRS

With the rapid development of the national economy and the improve of people’sliving standards，the demand of human for resources increased constantly How to getmore resources from the deep crust are a key issue for our economy to get a long ter-m sustainable development.Seismic method has greater detective depth and high acc-uracy in many of geophysical exploration methods, so seismic exploration method isone of the most important and effective means currently in the deep exploration at thepresent. The cable seismograph was widely used at home and abroad in the field ofseismic exploration. But a large number of cables made it difficult to lay, and hard tomeet the high density, the number of road, three-dimensional structure, the complexterrain of deep resource exploration environments’ demand. Cableless seismic dataacquisition system get rid of the heavy shackles of cable, completing seismic explora-tion operations by the mode that is wireless transmission and self-storage. It can be i-prove the flexibility of the system and reduce labor cost. However, because of lack-ing the real-time remote monitoring tool, the instrument’s collect data can not be effe-ctively guaranteed in the field. So it is not widely popularized.By analyzing the demand of cable-less seismograph’monitoring in the field anddepending on its’request about power, cost, timeliness, reliability and coverage requ-irements. Come up with a combined program of cable-less seismograph remote moni-toring based on Beidou satellite communications and GPRS network communicationtechnology. This system completed the design of hardware and software by using A-RM9processor as the core control device and Linux embedded operating system asthe design platform for application software. Embedding a Ultra-low-power430cop-rocessor and according to the stage to remotely monitoring the status of instrumentsand instrument modules,reducing as many the system power consumption as possible.Based on Microsoft Visual C++6.0designed the remote data monitoring and manag-ement software platform. Realized the functions of remote condition monitoring, pro- cess control operation, acquisition parameter settings for multiple cable-less seimog-raph at the same time. And through Google Earth Maps display software, completingthe location information of real-time monitoring and analysis equipment.After the test of remote quality monitoring system’s performance and stability, v-erifying the correctness and feasibility of the scheme. Compared with domestic and f-oreign similar seismograph, the system have a wide monitoring coverage, schedulingflexibility and long standby time high by using the remote quality monitoring system,At the same time, the quality of collect data has also been effectively guaranteed.
