[0035] The water supply working process of the rural water supply automatic control equipment provided in the embodiment of the utility model is explained as follows:

[0036] When the water level of the water storage pool is lower than the low water level threshold of the water storage pool, the MCU management unit reads the water level value of the water storage pool and judges whether the water level of the water storage pool is lower than the low water level threshold of the water storage pool; in order to protect the water pump motor from idling when starting, the MCU management unit also needs to read the water level of the water intake pool and judge whether the water level of the water intake pool is higher than the high water level threshold of the water intake pool; when the above conditions are met, the MCU management unit controls the water pump to start and begin pumping water;

[0037] During the water pumping process of the water pump, the water pump control device continuously reads the water level state of the water intake pool and the water storage pool, when the water level of the water intake pool is lower than the low water level threshold of the water intake pool, in order to protect the water pump from idling, the water pump control device stops the water pump from running at this time, otherwise, the water pump control device determines that the current water level of the water intake pool meets the water pumping requirement of the water pump, the water pump control device reads the water level state of the water storage pool, if the current water level of the water storage pool is higher than the high water level threshold of the water storage pool, the water pump control device stops the water pump from pumping water, otherwise, the water pump continues to pump water.

[0038] The water pump control device determines the communication link state between the water storage pool and the water pump control device when controlling the water pump to pump water. When the communication link between the water pump control device and the water storage pool is disconnected, the device enters a theoretical calculation liquid level state. The theoretical calculation is based on the water pump flow rate, the current water storage pool water level, the current water storage pool high water level threshold, the water storage pool capacity, and the theoretical timing time.

[0039] Specifically, in this embodiment, the calculation process is as follows:

[0040] Assuming that the water pump flow rate is Q (m^3 / h), the current water level of the water storage pool is A (cm), the high water level threshold of the water storage pool is B (cm), the low water level threshold of the water storage pool is C (cm), the capacity of the water storage pool is T (m^3), and the theoretical timing time is S (s), where the capacity of the water storage pool is the capacity when the water level reaches the high water level threshold from the low water level of the water storage pool, and the theoretical timing time S is the theoretical timing time required for the water storage pool to rise by 1 cm. The expression is as follows:

[0041]

[0042] When the water pump control device enters the theoretical calculation liquid level state, the water pump control device starts to accumulate according to the timing. When the accumulated time reaches the theoretical timing time S, the current liquid level A of the water storage pool is added by 1 cm. If the water pump control device is always in a state of disconnection with the water storage pool, the water pump control device will continuously accumulate the current liquid level value A of the water storage pool according to the theoretical calculation liquid level state, until the value of A is equal to the high water level threshold B of the water storage pool, and the water pump control device stops the water pump from running.

[0043] In this process, the water pump control device determines the current water level state of the water storage pool. When the water level of the water storage pool is lower than the low water level threshold of the water storage pool, the water pump control device stops the water pump from running.

[0044] In this process, the water pump control device continuously reads the communication link state between the water storage pool and the water pump control device. When the communication link between the two is restored, the water pump control device switches back to the actual measurement state from the theoretical calculation liquid level state.

[0045] Theoretical calculation example: If the current pool specifies that the water storage is 160 m^3, the water pump flow rate is 6 m^3 / h, and the high water level threshold of the water storage pool is 275 cm, the low water level threshold of the water storage pool is 25 cm, then the theoretical rising time of 1 cm is calculated as follows:

[0046]

[0047] Compared with the prior art, the rural water supply automatic control device has the problems of low accuracy, high cost, high labor resource consumption, need of manual control for pump start and stop, high risk of electric shock and low water supply safety. The device has the advantages of simple structure and convenient operation. The liquid level sensors arranged in the water taking pool and the water storage pool can read the liquid level data of the current pool in real time, and the high and low liquid level thresholds of the water taking pool and the water storage pool are set to control the start and stop of the water pump. During the water pumping process, the device monitors the water level of the water taking pool at all times. When the water level of the water taking pool is too low, the device actively closes the water pump to prevent the water pump from pumping water and causing the phenomenon of burning machine, improve the water supply safety, and eliminate the possibility that the water level data obtained by the liquid level gauge of the prior art is inaccurate. The water levels of the water taking pool and the water storage pool are automatically obtained, the device automatically controls the start and stop of the water pump, realizes the automatic control of water supply, and reduces the labor cost. The 4G communication mode is adopted to remotely transmit the water level data of the water storage pool to the water pump control device, so that the real-time monitoring and control of the water supply data are realized, and the device is convenient and fast. The entire device greatly reduces the cost of the prior art, and greatly improves the accuracy and safety of the water supply work.
