摘要（英）：

The invention provides a time service device for data collecting in earthquake deep well monitoring. The time service device comprises an earthquake sensor arranged at the bottom of a deep well. A microprocessor connected with the earthquake sensor is arranged at the bottom of the deep well. A GPS antenna and a GPS module are arranged on the ground of the deep well. The ground of the deep well is further provided with a first RS 485 level switching chip connected with the GPS module. A second RS 485 level switching chip connected with the GPS module is further arranged on the ground of the deep well. The bottom of the deep well is further provided with a first RS 485 level demodulation chip connected with the microprocessor, a long distance twisted pair which is connected with the first RS 485 level demodulation chip and the first RS 485 level switching chip is arranged between the first RS 485 level demodulation chip and the first RS 485 level switching chip, and the first RS 485 level demodulation chip transmits demodulated TTL level pulse per second signals to the microprocessor. A second RS 485 level demodulation chip which is connected with the microprocessor is further arranged at the bottom of the deep well, a long distance twisted pair which is connected with the second RS 485 level demodulation chip and the second RS 485 level switching chip is arranged between the second RS 485 level demodulation chip and the second RS 485 level switching chip, and the second RS 485 level demodulation chip transmits demodulated GPS data to the microprocessor. The invention further provides a time service method for data collecting in earthquake deep well monitoring.
