[0030] The power management device 150 is respectively connected to the new energy power generation device 140, the processor 130, and the wireless communication module 120 and is configured to supply power to the processor 130 and the wireless communication module 120 based on the first electric energy. Among them, the power management device 150 can convert the first electric energy into the supply voltage required by the processor 130 and the wireless communication module 120 for power supply.

[0031] Specifically, when the geological monitoring system 100 operates, the geological conditions of the current area are monitored by the acquisition device 110 to collect relevant geological information. The processor 130 sends the geological information to an external device through the wireless communication module 120 and the first antenna ANT1. The new energy power generation device 140 converts new energy into the first electric energy, and the power management device 150 converts the first electric energy into the supply voltage required by the processor 130 and the wireless communication module 120 for power supply. Thus, when the geological monitoring system 100 monitors geological information, it can be powered by new energy, which can save electric energy. Moreover, the power management device 150 can provide the supply voltage required by the processor 130 and the wireless communication module 120, with high power supply reliability and significantly extended battery life.

[0032] According to an embodiment of the present invention, as Figure 2 shown, the above-mentioned system 100 further includes: a positioning module 160, which is respectively connected to the second antenna ANT2 and the processor 130, and is configured to receive satellite positioning signals through the second antenna ANT2, determine the position information of the geological monitoring system 100 based on the satellite positioning signals by using RTK positioning technology, and send it to the processor 130; wherein, the processor 130 is further configured to send the position information to an external device through the wireless communication module 120 and the first antenna ANT1. Among them, the positioning module 160 can be a GNSS (Global Navigation Satellite System) module.

[0033] Specifically, the positioning module 160 receives satellite positioning signals through the second antenna ANT2, and then determines the position information of the geological monitoring system 100 according to the satellite positioning signals.

[0034] According to an embodiment of the present invention, as Figure 2 shown, the above-mentioned system 100 further includes: a memory 170, the memory 170 is connected to the processor 130, and the processor 130 is further configured to store the geological information and the position information in the memory 170.

[0035] That is to say, the memory 170 can store the geological information and location information of the geological monitoring system 100 for subsequent calling and querying. Among them, the memory 170 can be an SD card.

[0036] Taking the wireless communication module 120 as a cellular communication module, the positioning module 160 as a GNSS module, and the memory 170 as an SD card as an example, the GNSS module receives satellite information, sends the position parameters and time information of the geological monitoring system 100 to the processor 130 through the UART interface, and then transfers and stores them to the SD card through the IO interface of the SD card.

Among them, the energy storage battery 155 can be one of storage batteries such as lithium batteries and lead-acid batteries. In one embodiment, the charging control module 151 can be a lithium battery charging control chip with the model number CN3795, and the power monitor 152 can be a power monitoring chip with the model number UCD3138RHAR.

[0038] Specifically, when there is new energy input to the new energy power generation device 140, the charging control module 151 can store the first electric energy provided by the new energy power generation device 140 in the energy storage battery 155, or convert the first electric energy into the second electric energy and transmit it to the power monitor 152. It can also convert part of the first electric energy into the second electric energy and transmit it to the power monitor 152 while storing the first electric energy in the energy storage battery 155. When there is no new energy input to the new energy power generation device 140, the charging control module 151 can convert the electric energy of the energy storage battery 155 into the second electric energy and provide it to the power monitor 152. It should be understood that the required supply voltage of the wireless communication module 120 may not be the same as that required by the processor 130 and the positioning module 160. For example, the required supply voltage of the wireless communication module 120 is 4V, and the required supply voltage of the processor 130 and the positioning module 160 is 3.3V. The power monitor 152 can distribute the second electric energy to the first power supply module 153 and the second power supply module 154.

Among them, the third electric energy is the required supply voltage of the wireless communication module 120, and the fourth electric energy is the required supply voltage of the processor 130 and the positioning module 160. The first power supply module 153 and the second power supply module 154 can be DCDC modules, such as LDO (Low Dropout Regulaor, low dropout linear regulator), etc.

[0039] According to an embodiment of the present invention, as Figure 4 shown, the power management device 150 further includes a protection module 156 disposed between the charging control module 151 and the power monitor 152. The protection module 156 includes one or more of a surge suppression unit, an anti-reverse connection unit, and an overvoltage protection unit.

[0040] Among them, the surge suppression unit can prevent surge electric energy such as lightning from damaging the system 100. The anti-reverse connection unit can be a diode. When the circuit is reversely connected, the diode is cut off, thus realizing the anti-reverse connection function. The overvoltage protection unit can be an overvoltage / overcurrent protection chip, which mainly has three indicators: Vin input voltage, VCLAMP clamping voltage, and VOVP input overvoltage. When VCLAMP < Vin < VOVP, the output voltage of the overvoltage protection unit is clamped at VCLAMP; when Vin > VOVP, the overvoltage protection function is activated, and the internal heating field effect transistor of the overvoltage / overcurrent protection chip is turned off, and the output voltage is 0, thus realizing the overvoltage protection function.

[0042] Specifically, when receiving the satellite positioning signal, the second antenna ANT2 receives the satellite positioning signal and delivers it to the amplifier 161. The amplifier 161 amplifies the satellite positioning signal to increase the signal strength and delivers the amplified satellite positioning signal to the filter 162. The filter 162 filters the amplified satellite positioning signal to filter out clutter and delivers the filtered satellite positioning signal to the positioning chip 163. The positioning chip 163 uses RTK positioning technology to calculate the error value between the actual position and the position information of the geological monitoring system 100, and corrects the position information according to the error value, so as to determine the precise position of the geological monitoring system 100, and the positioning accuracy can reach the millimeter level. The positioning chip 163 sends the position information to the processor 130, and the processor 130 can send the position information to the wireless communication module 120.
