Design Of CSAMT Data Monitoring System Based On Multiple Wireless Communication Protocols

In the current geological exploration work environment, more and more to thearea of traffic inconvenience, work environment makes the geological explorationworkers had to carry instruments to walk to the exploration area, these characteristicsdecided to supplement or re acquisition data will consume a large amount ofmanpower and material resources. Therefore, urgent need a can in the explorationfield or wireless data monitoring system for remote monitoring of geologicalexploration data quality, to facilitate the staff to detect anomalies in data acquisition,and analyze the reasons, to take corresponding measures for as soon as possible.While most of the current geological prospecting instrument or no data monitoringfunction, or can only stand mounted display monitoring data in the collection, whichgreatly increased the detection instrument of power. Even with the wirelessmonitoring stations, but most are based on a single mode of transmission, adaptationability is poor in many circumstances, cannot meet the requirements of monitoringdata.Aiming at the above problems, based on the design of a multiple wirelesscommunication protocols (including Bluetooth, GPRS, Wi-Fi three kinds ofcommunication protocol) data monitoring system. Through the CSAMT dataacquisition station embedded multifunctional communication module(multifunctional integrated Bluetooth communication module, GPRScommunication module, Wi-Fi three), the realization of Android client and theCSAMT data acquisition and monitoring system of real time communication. The monitoring system is developed by Java language, including client and server. Thesystem software were installed collection station and Android client in CSAMT,CSAMT acquisition station in the collection of data at the same time, theintroduction of Jdom.jar open source library, read to parse the XML data, and thenthe analysis of the data through a custom protocol encryption transmission to theAndroid client. In the client, based on the custom protocol on the received datathrough data reduction, then based on the anisotropic diffusion filtering, datasmoothing, finally, the introduction of open source graphics library Achartengine.jar,defined by logarithmic coordinate, the analytical data reduction after drawing on thescreen, so as to realize the real-time display of data, real-time the purpose ofmonitoring data.The experimental results show that, on the basis of the design of the system canmeet the demand of the actual monitoring data, can bring convenience to geologicalexploration workers, has a good real-time performance and stability.
