[0002] Monitoring the dynamic changes of groundwater resources is of great practical significance. The changes in the quality and quantity of groundwater itself, the movement patterns of groundwater, and the environmental conditions that cause groundwater changes cannot be obtained through direct observation. In addition, groundwater pollution and problems such as ground subsidence caused by excessive groundwater exploitation are also slow-changing. Once these situations accumulate to a certain extent, they will cause irreversible damage to groundwater resources. Protecting groundwater must rely on long-term groundwater monitoring to timely grasp the dynamic changes of groundwater.

In the existing technology, there are multiple separately set terminals or modules such as RTU telemetry terminal, 4G module, Beidou data transmission terminal, etc. The integration is low, the equipment or modules are scattered, the number is large, and the integrated connection is complex.

[0047] In one embodiment, the Beidou acquisition and transmission terminal 2 includes an RTU telemetry terminal 20, a 4G module and a Beidou data transmission terminal integrated in one terminal. The RTU telemetry terminal 20 includes a microprocessor, an interface unit and a power supply unit. The 4G module includes a 4G transceiver unit and a 4G antenna. The Beidou data transmission terminal includes a Beidou RDSS transceiver unit and a Beidou transceiver antenna (including a Beidou transmitting antenna and a Beidou receiving antenna).

The 4G module and the Beidou data transmission terminal are split into multiple units with different functions, and then each unit is integrated into different functional modules according to the function, and then each functional module is integrated into one terminal, so that one terminal has multiple functions, and finally forms the circuit board of the Beidou acquisition and transmission terminal 2. The two circuit boards are combined into one by improving the circuit board, thereby reducing the connection between the circuit boards, and at the same time reducing the power consumption of the two circuit boards to the power consumption of one circuit board, and finally the area of ​​the solar panel 40 for powering the Beidou acquisition and transmission terminal 2 can be reduced, and the capacity of the power supply battery for storing the electricity generated by the solar panel 40 can be reduced, thereby reducing the cost.

[0052] The implementation principle of the groundwater level monitoring station in the embodiment of the present application is as follows: Beidou acquisition and transmission terminal 2 integrates RTU telemetry terminal 20, 4G module, and Beidou data transmission terminal into one terminal. One device has three functions. It adopts system integration design and modular assembly. It can adapt to the original site upgrade Beidou transformation and can also be used for new site construction. In the prior art, Beidou instantaneous power consumption is more than 30W, which leads to the large configuration of the existing solar power supply module, which is generally equipped with 30W solar panels and 40AH batteries, making the box relatively large. This application adopts a wind-solar complementary power supply system. The site can be equipped with 20W and 10AH power supply, making the battery box 12 smaller.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
