Description

Technical Field

[0001] The present invention belongs to the technical field of rural water supply, and in particular relates to a rural water supply automatic control device and method. Background Art

[0002] In the existing rural automatic water supply work, two water pools are often set up at one point, namely the water intake point water pool and the water storage point water pool. The water level of the water pool is obtained by manually reading the liquid level gauge. This method requires the water intake pool manhole cover to be opened for a long time. This method is not only unsafe but also easy to introduce debris into the water intake pool, affecting the water quality of the water pool. The data reading is extremely inaccurate, especially at night or under poor lighting conditions. Manual supervision is required during the water filling of the water storage pool. In order to ensure that the water storage pool can be filled, personnel need to be arranged to shuttle between the water intake pool and the water storage pool to provide information on the water level of the water pool. In this process, a large amount of human resources is consumed and the cost is high. The start and stop of the water pump needs to be controlled by someone, which is easy to cause electric shock accidents, and the safety of water supply cannot be guaranteed.

The water supply equipment in this patent application uses a scale to observe the water level, which has the problem of inaccurate liquid level reading. In addition, it also requires manual observation, which has high labor costs and has the same disadvantages as the prior art.

[0004] Therefore, how to improve the accuracy and safety of rural water supply and reduce the cost of water supply is an urgent problem to be solved by people in this technical field. Summary of the invention

[0005] In view of the deficiencies of the prior art, the purpose of the present invention is to provide an automatic control device for rural water supply to solve the problems of high rural water supply cost, low water supply accuracy and safety in the prior art; in addition, the present invention also provides an automatic control method for rural water supply.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] In a first aspect, the present invention provides a rural water supply automatic control device, comprising:

[0008] A water reservoir level meter, a water reservoir solar power supply module, a water reservoir 4G communication module slave, a water pump control device, a water reservoir 4G communication module host, a water intake pool level meter, a water supply pump and a water supply pipeline; the water reservoir level meter and the water reservoir 4G communication module slave are respectively connected to the water reservoir solar power supply module, the water reservoir level meter is arranged in the water reservoir, the water reservoir 4G communication module host and the water intake pool level meter are respectively connected to the water pump control device, the water intake pool level meter is arranged in the water intake pool, the water pump control device is also connected to the water supply pump, and the water supply pipeline is arranged in the water reservoir through the water supply pump at one end and in the water intake pool at the other end.

[0009] Furthermore, the water pump control device includes an MCU management unit, a relay control unit, a data storage module, a water intake tank liquid level sensor and a water storage tank liquid level sensor, and the relay control unit, the data storage module, the water intake tank liquid level sensor and the water storage tank liquid level sensor are respectively communicatively connected to the MCU management unit.

[0010] Furthermore, the water pump control device also includes a 4G communication master module and a 4G communication slave module, one end of the 4G communication slave module is communicatively connected to the water reservoir liquid level sensor, the other end of the 4G communication slave module is communicatively connected to the 4G communication master module, and the other end of the 4G communication master module is communicatively connected to the MCU management unit.

[0011] Furthermore, it also includes a water supply monitoring platform for displaying water supply data, and the water supply monitoring platform is connected to the water pump control device.

[0012] Furthermore, the water pump control device also includes a water supply monitoring unit, and the water supply monitoring unit is connected to the MCU management unit.

[0013] Furthermore, the circuit of the water pump control device includes a relay K1, a diode D1 and a transistor Q1, one end of the relay K1 is connected to the anode of the diode D1, the other end of the relay K1 is connected to the cathode of the diode D1, the anode of the diode D1 is also connected to the collector of the transistor Q1, the emitter of the transistor Q1 is grounded, so the base of the transistor Q1 is connected to the RELAY end.

[0014] In a second aspect, the present invention further provides a method applied to the above device, comprising the following steps:

[0015] S10. When the water level in the reservoir is lower than the low water level threshold of the reservoir, the MCU management unit reads the water level value of the reservoir to determine whether the water level in the reservoir is lower than the low water level threshold of the reservoir; the MCU management unit reads the water level of the water intake pool to determine whether the water level in the water intake pool is higher than the high water level threshold of the water intake pool; when all the above conditions are met, the MCU management unit controls the water pump to start and start pumping water; S20. During the pumping process, the water pump control device continuously reads the water level status of the water intake pool and the reservoir. When the water pump control device reads that the water level in the water intake pool is lower than the low water level threshold of the water intake pool, the water pump control device shuts down the water pump operation, otherwise the water pump control device determines that the current water level in the water intake pool meets the pumping requirements, and the water pump control device reads the water level status of the reservoir. If the current water level of the reservoir is higher than the high water level threshold of the reservoir, the water pump control device stops the water pump pumping, otherwise the water pump continues to pump water.

[0016] Furthermore, when the water pump control device controls the water pump to pump water, it continuously determines the status of the communication link between the water reservoir and the water pump control device. When the communication link between the water pump control device and the water reservoir is disconnected, the water pump control device enters the theoretical calculation liquid level state. The theoretical calculation is based on the water pump flow, the current water level of the water reservoir, the current high water level threshold of the water reservoir, the water reservoir capacity and the theoretical timing time.

[0017] Furthermore, let the pump flow be Q, the current water level of the reservoir be A, the high water level threshold of the reservoir be B, the low water level threshold of the reservoir be C, the capacity of the reservoir be T, and the theoretical timing time be S, where the capacity of the reservoir is the capacity when the water level reaches the high water level threshold of the reservoir from the low water level of the reservoir, and the theoretical timing time S required for the water in the reservoir to rise by 1 cm is theoretically calculated, and the expression is as follows:

[0018]

[0019] Furthermore, 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 is greater than the theoretical timing time S, the current liquid level A of the water reservoir is accumulated by 1 cm. If the water pump control device has been in a state where the communication link with the water reservoir is disconnected, the water pump control device will continue to accumulate the current liquid level value A of the water reservoir 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 reservoir, and the water pump control device stops the water pump operation; the water pump control device determines the current water level state of the water intake tank. When the water level of the water intake tank is lower than the low water level threshold of the water intake tank, the water pump control device stops the water pump operation; the water pump control device continuously reads the communication link state between the water reservoir and the water pump control device. When the communication link between the two is restored, the water pump control device switches from the theoretical calculation liquid level state back to the actual measurement state.

[0020] Compared with the prior art, the rural water supply automatic control device and method provided by the present invention have at least the following beneficial effects:

[0021] The existing technology of automatic water supply has low accuracy, consumes a lot of human resources, and has high costs. The start and stop of the water pump requires human control, which is easy to cause electric shock accidents, and the safety of water supply cannot be guaranteed. The present invention has a simple structure and convenient operation. The liquid level sensor set in the water intake pool and the water storage tank reads the liquid level data of the current water pool in real time, and sets the high and low liquid level thresholds of the water intake pool and the water storage tank to control the start and stop of the water pump. During the pumping process, the device always monitors the water level of the water intake pool. When the water level value of the water intake pool is too low, the device actively shuts down the water pump to prevent the water pump from failing to pump water and causing the machine to burn out, thereby improving the safety of water supply and eliminating the possibility of inaccurate water level data obtained by the liquid level gauge in similar existing technologies; the water levels of the water intake pool and the water storage tank are automatically obtained, and the device automatically controls the start and stop of the water pump, realizing automatic control of water supply and reducing labor costs; the 4G communication method is used to remotely transmit the water level data of the water storage tank to the water pump control device to realize real-time monitoring and control of water supply data, which is convenient and fast. The cost of the whole invention is greatly reduced compared with the prior art, and the accuracy and safety of water supply work are greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

The water tank solar power supply module 2 continuously provides power to the water tank level meter 1 and the water tank 4G communication module slave 3. The water pump control device 5 collects the real-time water level of the water tank through the water tank 4G communication module host 6. The water pump control device 5 collects the liquid level data of the water intake tank in real time. The water pump control device 5 determines whether it is necessary to start or stop the water supply pump according to the water level information of the water intake tank and the water reservoir. The water supply pump 8 injects drinking water into the water tank through the water supply pipe 9.

[0039] Furthermore, in this embodiment, the device also includes a water supply monitoring platform 4 for displaying water supply data, and the water supply monitoring platform 4 is connected to the water pump control device 5 .

[0040] Furthermore, in the present embodiment, the water pump control device includes an MCU management unit, a relay control unit, a data storage module, a water intake pool liquid level sensor and a water reservoir liquid level sensor, and the relay control unit, the data storage module, the water intake pool liquid level sensor and the water reservoir liquid level sensor are respectively communicatively connected to the MCU management unit; the water pump control device also includes a 4G communication master module and a 4G communication slave module, one end of the 4G communication slave module is communicatively connected to the water reservoir liquid level sensor, the other end of the 4G communication slave module is communicatively connected to the 4G communication master module, and the other end of the 4G communication master module is communicatively connected to the MCU management unit.

[0041] Furthermore, in this embodiment, the water pump control device 5 also includes a water supply monitoring unit, and the water supply monitoring unit is connected to the MCU management unit.

[0042] Furthermore, in this embodiment, the circuit of the water pump control device 5 includes a relay K1, a diode D1 and a transistor Q1, one end of the relay K1 is connected to the positive electrode of the diode D1, the other end of the relay K1 is connected to the negative electrode of the diode D1, the positive electrode of the diode D1 is also connected to the collector of the transistor Q1, the emitter of the transistor Q1 is grounded, so the base of the transistor Q1 is connected to the RELAY end.

In the water pump control circuit, V5V is the relay supply voltage, R1 is a current limiting resistor to prevent the relay from being damaged by excessive instantaneous current when the relay is turned on, and D1 is a bidirectional common anode Schottky diode to protect the relay from being mistakenly started due to excessive reverse voltage.

[0043] The present invention also provides a method applied to the above device, combining Figures 3 to 6 In this embodiment, the method includes the following steps:

[0044] S10. When the water level in the reservoir is lower than the low water level threshold of the reservoir, the MCU management unit reads the water level value of the reservoir to determine whether the water level in the reservoir is lower than the low water level threshold of the reservoir; in order to prevent the water pump motor from idling due to the low water level in the water intake pool when starting, the MCU management unit also needs to read the water level in the water intake pool to determine whether the water level in 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 start pumping water; S20. The water pump pumps water During the watering process, the water pump control device continuously reads the water level status of the water intake pool and the water storage tank. When the water pump control device reads that 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 shuts down the water pump operation. Otherwise, the water pump control device determines that the current water level of the water intake pool meets the water pumping requirements. The water pump control device reads the water level status of the water storage tank. If the current water level of the water storage tank is higher than the high water level threshold of the water storage tank, the water pump control device stops the water pumping, otherwise the water pump continues to pump water.

[0045] Furthermore, in this embodiment, when the water pump control device controls the water pump to pump water, it will always determine the status of the communication link between the water reservoir and the water pump control device. When the communication link between the water pump control device and the water reservoir is disconnected, the device enters the theoretical liquid level calculation state. The theoretical calculation is based on the water pump flow, the current water level of the water reservoir, the current high water level threshold of the water reservoir, the water reservoir capacity and the theoretical timing time.

[0046] Specifically, in this embodiment, the calculation process is as follows:

[0047] Assume that the pump flow is Q (m^3 / h), the current water level of the reservoir is A (cm), the high water level threshold of the reservoir is B (cm), the low water level threshold of the reservoir is C (cm), the capacity of the reservoir is T (m^3), and the theoretical timing time is S (s), where the capacity of the reservoir is the capacity when the water level reaches the high water level threshold from the low water level of the reservoir. The theoretical timing time S required for the water level of the reservoir to rise by 1 cm is theoretically calculated, and the expression is as follows:

[0048]

[0049] When the water pump control device enters the theoretical calculated liquid level state, the water pump control device starts to accumulate according to the timing. When the accumulated time reaches the maximum theoretical timing time S, the current liquid level A of the water reservoir is accumulated by 1cm. If the water pump control device has been in a state where the communication link with the water reservoir is disconnected, the water pump control device will continue to accumulate the current liquid level value A of the water reservoir according to the theoretical calculated liquid level state until the value of A is equal to the high water level threshold B of the water reservoir. The water pump control device stops the water pump operation.

[0050] During this process, the water pump control device determines the current water level status of the water intake pool. When the water level of the water intake pool is lower than the low water level threshold of the water intake pool, the water pump control device stops the water pump operation.

[0051] During this process, the water pump control device continuously reads the status of the communication link between the water reservoir and the water pump control device. When the communication link between the two is restored, the water pump control device switches from the theoretical calculation liquid level state back to the actual measurement state.

[0052] Theoretical calculation example: If the current water storage in the water pool is 160m^3, the water pump flow is 6m^3 / h, the high water level threshold of the water pool is 275cm, and the low water level threshold of the water pool is 25cm, then the theoretical rise time of 1cm is calculated as follows:

[0053]

[0054] Compared with the prior art, the automatic water supply control device and method of the rural water supply described in the above embodiment have low accuracy of automatic water supply in the prior art, and also need to consume a lot of human resources, high cost, and the start and stop of the water pump need to be controlled by someone, which is easy to cause electric shock accidents, and the safety of water supply cannot be guaranteed. The present invention has a simple structure and convenient operation. The liquid level sensor set in the water intake pool and the water storage pool reads the liquid level data of the current water pool in real time, and sets the high and low liquid level thresholds of the water intake pool and the water storage pool to control the start and stop of the water pump. During the pumping process, the device always monitors the water level of the water intake pool. When the water level value of the water intake pool is too low, the device actively shuts down the water pump to prevent the water pump from failing to pump water and causing the machine to burn out, thereby improving the safety of water supply and eliminating the possibility of inaccurate water level data obtained by the liquid level gauge in the prior art; the water levels of the water intake pool and the water storage pool are automatically obtained, and the device automatically controls the start and stop of the water pump, realizing automatic control of water supply and reducing labor costs; the 4G communication method is used to remotely transmit the water level data of the water storage pool to the water pump control device to realize real-time monitoring and control of water supply data, which is convenient and fast. The cost of the whole invention is greatly reduced compared with the prior art, and the accuracy and safety of water supply work are greatly improved.

10. The method according to claim 9, characterized in that 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 is greater than the theoretical timing time S, the current liquid level A of the water reservoir is accumulated by 1 cm. If the water pump control device is always in a state where the communication link with the water reservoir is disconnected, the water pump control device will continue to accumulate the current liquid level value A of the water reservoir according to the theoretical calculation liquid level state until the value of A is equal to the high water level threshold value B of the water reservoir, and the water pump control device stops the water pump operation; The water pump control device determines the current water level status of the water intake pool, and when the water level of the water intake pool is lower than the low water level threshold of the water intake pool, the water pump control device stops the water pump operation; The water pump control device continuously reads the communication link status between the water reservoir and the water pump control device. When the communication link between the two is restored, the water pump control device switches from the theoretical calculation liquid level state back to the actual measurement state.
