Research On Positioning And Data Transmission Technology Of Wireless Distributed Resource Exploration Geophones

Wireless network-based distributed terrestrial resource exploration technology represents the development direction of resource exploration technologies.The precise positioning of geophones and high-speed,high-efficiency and reliable data transmission are the key technologies of wireless distributed resource exploration equipment,and are also the current international resource exploration field.research focus.This article focuses on these two key technologies to carry out research work.First,based on GPS differential positioning algorithm,GPS base station,low-cost GPS module(mobile station)and wireless network,the low-cost GPS differential accurate positioning of the detector is studied.The seismic workstation receives positioning information from the GPS base station,resolves the information and transmits the information to the positioning MCU of the acquisition node through the Wi-Fi wireless network,and the positioning MCU combines the positioning information acquired from the GPS mobile station to implement accurate differential positioning by the algorithm.Second,based on the 32-bit dedicated ADC ADS 1282,non-volatile FLASH K9WAG08U0A,Wi-Fi module GS2011,designed a data acquisition device that combines data acquisition,data storage,and data transmission into a single,dual-storage architecture,enabling data acquisition and the quasi-synchronization of data transmission,without increasing the wireless transmission rate,improves the transmission efficiency of seismic acquisition data,shortens the time for data transmission,and improves the practicality of the data collector in resource exploration.In order to further improve the performance of wireless transmission,the paper discusses the feasibility of using congestion control,heartbeat packet detection and other mechanisms to enhance wireless transmission performance.Finally,data acquisition,differential localization of detectors,and data transmission tests were performed.The results show that the data collector,geophone differential location unit,and data transmission unit designed in this paper achieve the expected functions and achieve low-cost differential localization of geophones,quasi-synchronous data acquisition and data transmission.The pressure of data transmission rate is reduced,the data transmission time is shortened,and the work efficiency of resource exploration is greatly improved.
