[0024] See Figure 2, the RTU acquisition terminal includes a rechargeable battery unit 5, a power management unit, an MCU main board 4, an input / output IO unit, a storage unit, a display unit, and a communication unit. The rechargeable battery unit 5 is connected to the power management unit.

[0026] Working principle: The low-light solar panel 10 is used for low-light acquisition, following the basic principle of the photovoltaic effect. The solar cell converts light energy into electrical energy. From the perspective of the light intensity requirement, most ordinary light energy acquisition and power generation are equipped with single-crystal / polycrystalline photovoltaic panels that perform better under high outdoor light intensity. However, this requires sufficient direct sunlight and light duration, and the amount of power generation is directly related to the light intensity. Under the condition of high light intensity on sunny days, the power generation is significantly higher than other periods. In addition, different regions and different seasons also have a direct impact on the efficiency of ordinary light energy acquisition and power generation.

[0027] The micro-light energy acquisition mainly uses a low-light type amorphous silicon photovoltaic panel, which can achieve more efficient photoelectric conversion in an indoor light and non-direct sunlight environment. The requirement for light intensity is much lower than that of ordinary light energy acquisition and power generation. Even in a low-light environment of 50-100 lux indoors, stable energy acquisition can still be achieved, and it is less affected by the light intensity.

[0028] Since the micro-light energy acquisition has a lower requirement for light intensity, the light intensity indoors and outdoors is sufficient to meet the energy collection. It obtains energy through the natural environment, rather than relying on the power generated by batteries or other types. The low-light solar panel 10 is embedded and installed on the surface of the RTU terminal housing. The rechargeable battery unit 5 is installed inside the RTU terminal housing. The micro-light energy is converted into electrical energy. The power management unit manages and distributes the electrical energy to other units for power supply, and stores the remaining electrical energy in the rechargeable battery unit 5 to maintain the normal continuous operation of the RTU acquisition terminal. To increase the overall protection, waterproof, and dustproof performance of the RTU, a high-strength explosion-proof glass is installed on the outer surface of the embedded installation surface of the low-light solar panel 10. The low-light solar panel 10 is connected to the MCU main board 4 through a wire, and the rechargeable battery unit 5 is connected to the MCU main board 4 through a wire.

[0029] Most of the time, the RTU acquisition terminal works in the sleep mode, is awakened by preset time intervals and specific events, performs data acquisition through a short working cycle, and goes to sleep again after uploading, ensuring that the overall power consumption is at a low level.

[0030] The above embodiments are implemented on the premise of the technical solution of the present utility model, and detailed implementation manners and specific operation processes are given. However, the protection scope of the present utility model is not limited to the above embodiments. The methods used in the above embodiments are all conventional methods unless otherwise specified.
