[0037] The relay module 2 is used for controlling the time relay module 3 to enter an electrically closed state in the case that the electric signal is received.

[0038] The time relay module 3 is used for supplying power to the alarm module 4 in the electrically closed state, and the power supply duration of the time relay module 3 is a preset duration.

[0039] The alarm module 4 is used for outputting a rain amount alarm signal.

[0040] ​For example, if the preset time period is 0.5 hours, the preset rainfall threshold is 40 mm. If the preset time period is 1 hour, the preset rainfall threshold is 60 mm. If the preset time period is 2 hours, the preset rainfall threshold is 80 mm.

[0041] In summary, the rainfall monitoring module 1 monitors the rainfall in real time, and outputs an electric signal when the rainfall in the preset time period is greater than the preset rainfall threshold. After receiving the electric signal, the relay module 2 controls the time relay module 3 to enter the electrically closed state, so that the power supply time reaches the preset time length, thereby ensuring that the alarm module 4 can alarm for a long enough time. The relay module 2 and the time relay module 3 can realize accurate signal transmission, thereby improving the rainfall detection accuracy and reducing the false negatives.

[0042] Optionally, the relay module 2 includes a first common terminal and a first normally open contact, and the time relay module 3 includes a second signal input terminal, a second common terminal and a second normally open contact; the first common terminal and the second common terminal are electrically connected; the first normally open contact and the second signal input terminal are electrically connected; and the second normally open contact is electrically connected to the power input terminal of the alarm module 4.

[0043] For example, referring to Figure 2 , the first common terminal on the relay module 2 is the COM terminal, the first normally open contact is the NO terminal, the second signal input terminal on the time relay module 3 is the IN terminal, the second common terminal is the COM terminal, and the second normally open contact is the NO terminal. The COM terminal on the relay module 2 is electrically connected to the COM terminal on the time relay. The NO terminal on the relay module 2 is electrically connected to the IN terminal on the time relay module 3. The NO terminal on the time relay module 3 is connected to the power input terminal of the alarm module 4. Further, the NO terminal and the COM terminal are used in cooperation.

Further, if the output voltage of the second voltage output terminal is 12V, in the time relay module 3, when the time relay module 3 is triggered, the NO terminal on the time relay module 3 connects to the COM terminal. Because the COM terminal on the time relay module 3 is electrically connected to the second voltage output terminal, the voltage at the COM terminal will be the same as the voltage at the second voltage output terminal, becoming 12V. Also, because the NO terminal is connected to the COM terminal, the voltage at the NO terminal will also become 12V. Since the NO terminal on the time relay module 3 is electrically connected to the power input terminal of the alarm module 4, power is supplied to the alarm module 4, causing the alarm module 4 to activate.

[0048] Optionally, the power module includes a battery controller 51 and a voltage conversion module 52; the battery controller 51 includes a first voltage output terminal, and the voltage conversion module 52 includes a second voltage output terminal and a voltage conversion input terminal, with the voltage output terminal and the voltage conversion input terminal being electrically connected; the voltage converter is used to convert the first voltage output by the battery controller 51 into the second voltage.
