Research On Wireless Transmission Of Shallow Seismograph

In the heavy,magnetic,electrical,earthquake,radioactive five categories of geophysical exploration methods,seismic wave exploration method has been played a pivotal role,which shallow seismic exploration method is indispensable.As shallow seismic exploration operating environment is often more complex,compared with the traditional shallow earthquake cable transmission system,wireless transmission system is low in production cost,easy to maintain,light and convenient,more suitable for complex construction environment.Therefore,for the shallow seismic surveyor wireless transmission system research,is an important practical value and significance of the work.The current "WGD-1" wireless transmission shallow seismic exploration instrument,the wireless transmission rate is low,and can not fully realize the real-time data transmission.In view of this,this paper presents a new idea of multi-channel wireless transmission system,at the same time the embedded technology and 433 M wireless transceiver technology are assimilated into the shallow seismic survey instrument wireless transmission system,the "WGD-1" wireless transmission shallow seismic survey is improved to study,improve the wireless transmission rate of data,real-time transmission function,to solve the equipment bulky,inconvenient to carry the problem.In this paper,the main structure of the main research content,innovation,and wireless network shallow seismic survey of the overall structure of the design and working principle,the wireless transmission system of shallow seismic survey is described in detail,namely single channel wireless transmission system.First of all,compared the performance of several wireless communication methods,the choice of 433 M wireless network technology,using the Silicon Labs SI4463 wireless module,through the wireless transmission module circuit design,STM32 and SI4463 interface circuit design,JTAG debug interface circuit design,power circuit design to achieve,for the wireless transmission system has laid a hardware foundation;At the same time the use of ARM embedded technology,built a software environment,the design of the serial driver,data transmission and reception procedures.Finally,through the system's data transmission protocol and workflow to achieve the data wireless transmission process.In this paper,the dual-channel wireless transmission system is taken as an example,and the research work of multi-channel wireless transmission system is emphasized.Mainly in the single-channel wireless transmission system host system on the main control module,and then add two wireless transmission module Radio,a total of three wireless modules.Among them,specifically with a wireless module for command release and response,the other two wireless modules used to send and receive data.Finally,to achieve dual-channel wireless transmission system data transmission process.And finally the single-channel wireless transmission system and dual-channel wireless transmission system for comparative testing,the results show that the proposed dual(multi)channel wireless transmission system is feasible,two(more)channels at the same time transmission of data,parallel transmission,do not interfere with each other;While dual-channel wireless transmission system compared with single-channel,its wireless transmission rate has increased nearly doubled,real-time data transmission and processing results are ideal,to achieve the desired results.
