Abstract Mobile distributed seismic exploration system is a new design concept of resource exploration system, composed of artificial seismic source, seismic data acquisition vehicle array, information transmission system, the central station and software. Acquisition vehicle is the core unit of the exploration system, corresponding to the traditional exploration system a collection point, composed of a vehicle body, a detector in device, wireless remote data acquisition system constitute, responsible for carrying detector, in location and precise location, seismic data acquisition and transmission of the key tasks. This research is specially designed and designed the data acquisition system based on Wi-Fi wireless remote control technology, and realizes the remote and high resolution, low noise data acquisition and wireless information transmission of seismic wave.. The acquisition system is based on the TI TM4C123GH series embedded microprocessor by the preamplifier, data acquisition unit, data storage unit and Wi-Fi wireless communication unit.. The main research contents of this paper are as following three aspects: (1) design and debug the hardware and software of the high resolution and low noise data acquisition system based on the TI TM4C123GH series embedded microprocessor, and realize the data acquisition.. (2) design and debug the hardware and software of the wireless data transmission system based on the TI TM4C123GH series embedded microprocessor and Wi-Fi module, and realize the wireless communication. Keywords Low noise Seismic data acquisition Wireless information transmission
