Field discrete type digital seismic recorder

The utility model provides a field discrete type digital seismic recorder, which comprises a detector, an interface circuit, a sampling retainer, an A/D converter, a CPU, a GPS module and a data memory. The detector is used for detecting seismic wave signals. The signal output end of the detector is connected with the signal input end of the interface circuit. The signal output end of the interface circuit is connected with the signal input end of the sampling retainer. The signal output end of the sampling retainer is connected with the signal input end of the A/D converter. The signal output end of the A/D converter is connected with the signal input end of the data memory. The clock signal input end of the data memory is connected with the signal output end of the GPS module. The GPS module is coupled to an antenna. According to the technical scheme of the utility model, by means of a wireless cable, the connection restriction of a conventional wired cable can be thoroughly avoided. Therefore, the field di
