Abstract :
This paper introduces the design of wireless vibration detection node, which used in seismic exploration, this node can pick up three-dimensional vibration signal effectively. The node of the hardware circuit is composed of the following parts: FPGA as the cybernetics core, MEMS three-dimensional accelerometer to acquire vibration signal, the combination of ADC and SD card to collect and store the data by means of the negative delay mechanism, wireless transceiver module to transmit the data. Experiment results show that this node solve the problem of traditional seismic prospecting instrument, achieve the wide band, high between shaft cross talk depression goals.
