Research And Design Of Network Digital Detector

With the continuous development of information technology, the traditionalgeophone cannot meet the needs of seismic exploration technology. Especially inrecent years, the development of Seismic prospecting, request detector of highresolution, large dynamic range, low distortion and high anti-interference ability, etc.,these are not the traditional geophone can meet. Geophone is the key of seismic dataacquisition equipment, its performance is good or bad directly affect the quality ofseismic data. Digital detector based on MEMS acceleration sensor has the advantagesof wide band and high frequency, suitable for high resolution seismic exploration.This paper through the study of seismic geophone at home and abroad, as well asrequirements of seismic prospecting, network digital detector based on MEMStechnology is designed. This thesis designs the network of digital geophone detectorof abandoned the traditional digital seismograph collection box structure, the MEMSacceleration sensor, A/D converter and micro controller all wrapped into a smallgeophone shell, thereby significantly improving the anti-interference ability of thesystem. Digital detector connected each detector through the RS-485bus as a node,the node as a routing node, routing node uses the wireless module to automatically setup a wireless network, to the data transmission to the field data obtained from some ofthe digital detector to collect the car PC. Again through the data acquisition softwarefor data storage, digital geophone is the combination of cable network and wirelessnetwork, and the entire network is connected by routing nodes.The research significance of this paper is to speed up the detector in domesticdigital networked process, draw lessons from foreign advanced technolo gyapplication, and the world advanced technology standards. This design adopts thecombination of wired and wireless data transmission network data transmission ofseismic wave in the form of data collection, the design of the network digitalgeophone has obtained certain achievement。Hope can to the detector miniaturization,digitalization and mass play a role. Based on network research and design of digitalgeophone, hope to be able to promote technological progress in oil and gasexploration and development, to reduce the risk of exploration, development andenhance reservoir recovery has a certain significance.
