Earthquake exploration data collecting system

The utility model discloses an earthquake exploration data collecting system. A plurality of radio detectors with independent IP address of each are connected in series to form the numerical chain with the same digit track structure SMGs. Every large cable interface unit SLIM is connected with two series of numerical sensor SMGs numerical chain, with the track gap as 5 or 10 meters. One end of the digital passage cable is connected with the numerical chain, while the other end is connected with the data linkage station, which is further connected with the central recording system through numerical cables. The central record system consists of the screen display unit that replays the collected data. A computer with the RAM storage is further provided in the large cable interface SLIM. In every receiving line of the three-dimensional SEG-D format, a data administration unit IXU is arranged. The transmission velocity of transport cable is 100Mbps. Sampling point transportation is permitted. When the system runs, 2,000 tracks/ 1ms sampling is for the two- dimensional and 30,000 tracks/ 1ms sampling for the three- dimensional.
