The host computer adopts a Modbus communication protocol, touch screen intelligent control, simple operation and safety intelligence, greatly reduces the difficulty of field operators.

[0031] In a specific embodiment, the external power supply voltage input by the seismic source system 14 needs to be detected for voltage high and low and fluctuation range to prevent overvoltage and undervoltage from damaging the system. The voltage detection module 141 is specifically a voltage transmitter, which converts the measured AC voltage into a DC voltage output in linear proportion for detection. When the DC voltage exceeds AC 250V, a power overhigh alarm is given. When the DC voltage is lower than AC 205V, a power undervoltage alarm is given.
