In addition, in the description of the present invention, unless otherwise stated, the meaning of "a plurality of" is two or more.

[0049] As Figure 1 shown, the present invention discloses an efficient and precise water and fertilizer irrigation integrated machine, comprising:

[0050] A monitoring terminal, connected to the solenoid valve, sensor, water pump, and stirring pump on the efficient and precise water and fertilizer irrigation integrated machine, capable of acquiring data through the sensor and performing operations such as data processing, storage, and display, and also capable of controlling the opening and closing of the solenoid valve, water pump, and stirring pump. Specifically, it can be an operating platform or a computer with the above functions.

[0051] A clean water tank 4, used to store the clean water supplied to the mother liquid tank 1 and the mixing tank 2.

[0052] Specifically, the clean water tank 4 receives clean water transported by an external water supply device, such as a faucet, through a water inlet pipe. A clean water monitoring component is provided inside the clean water tank 4, including a third liquid level sensor provided inside the clean water tank 4 and a water inlet solenoid valve 401 provided on the water inlet pipe that can control the on / off of the water inlet pipe. The monitoring terminal can acquire the liquid level of the clean water tank 4 through the third liquid level sensor and can also control the water storage volume of the clean water tank 4 by setting the upper and lower liquid level limits of the third liquid level sensor.

[0053] When the liquid level of the clean water tank 4 is lower than the lower liquid level limit of the third liquid level sensor, the monitoring terminal controls the water inlet solenoid valve 401 to open, and clean water enters the clean water tank 4 through the water inlet pipe via the water inlet solenoid valve 401 until the liquid level of the clean water tank 4 reaches the upper liquid level limit of the third liquid level sensor, and the monitoring terminal controls the water inlet solenoid valve 401 to close, stopping the injection of clean water into the clean water tank 4.

[0054] The clean water monitoring component further includes a clean water pump provided in the clean water tank 4, and the monitoring terminal can control the clean water pump to extract the clean water in the clean water tank 4 and output it to the mother liquid tank 1 or the mixing tank 2.

[0055] A mother liquid tank 1, used to hold clean water and fertilizer, and, the mother liquid formed after mixing clean water and fertilizer.

[0056] Specifically, since the general water and fertilizer formula contains multiple fertilizers, there are multiple mother liquor tanks 1 set according to the types of specific fertilizers, and each type of fertilizer has a corresponding mother liquor tank 1. Each mother liquor tank 1 can obtain the clear water transported from the clear water tank 4 through the second water injection pipe 101. In other embodiments, the mother liquor tank 1 can also directly obtain clear water from an external water supply device, such as a faucet, through the second water injection pipe 101.

[0057] Each mother liquor tank 1 is correspondingly provided with a mother liquor monitoring component, specifically including:

[0058] A third electromagnetic valve 102, which is arranged on the second water injection pipe 101 and can realize the on-off of the second water injection pipe 101 under the control of the monitoring terminal.

[0059] A third flowmeter 103, which is arranged between the third electromagnetic valve 102 and the water outlet of the second water injection pipe 101. The monitoring terminal can obtain the inflow of clear water into the mother liquor tank 1 after passing through the third electromagnetic valve 102 through it.

[0060] A second liquid level sensor, which is arranged in the mother liquor tank 1. After only clear water is injected into the mother liquor tank 1, the monitoring terminal can obtain the clear water liquid level in the mother liquor tank 1 through the second liquid level sensor.

[0061] A mother liquor stirring pump, which can stir the clear water and fertilizer to form mother liquor under the control of the monitoring terminal.

[0062] In this embodiment, the mother liquor is generally a fertilizer solution with a relatively high concentration. Therefore, the mixing frequency of the mother liquor is often relatively low. For example, it is mixed and proportioned once every month or two. Specifically, the mixing process of the mother liquor is as follows:

[0063] The monitoring terminal controls the clear water pump to extract the clear water in the clear water tank 4 and output it to the second water injection pipe 101, and opens the third electromagnetic valve 102 to make the second water injection pipe 101 conductive. At the same time, the monitoring terminal obtains the inflow of clear water into the mother liquor tank 1 in real time through the third flowmeter 103. When the inflow of clear water into the mother liquor tank reaches the preset water injection value of the mother liquor tank 1, the monitoring terminal closes the clear water pump and the third electromagnetic valve 102.

[0064] The monitoring terminal obtains the clear water liquid level in the mother liquor tank through the second liquid level sensor and converts it into the clear water capacity of the mother liquor tank, and then compares the inflow of clear water into the mother liquor tank and the clear water capacity of the mother liquor tank. If the error between the two is not greater than the preset water injection error value of the mother liquor tank, the management personnel add the corresponding fertilizer to the mother liquor tank 1 according to the planned proportioning, and the monitoring terminal controls the mother liquor stirring pump to work to stir the clear water and fertilizer to form mother liquor. Otherwise, the monitoring terminal outputs an alarm message or an alarm prompt sound to remind the management personnel.

[0065] In addition, an EC sensor, a PH sensor, and a water temperature sensor are also provided in the mother liquor tank 1. After the mother liquor is stirred, the monitoring terminal can obtain the EC value, PH value, and temperature of the mother liquor in the mother liquor tank 1 through the EC sensor, PH sensor, and water temperature sensor. When the second liquid level sensor and the third flowmeter 103 are damaged, resulting in inaccurate water intake and water level in the mother liquor tank of the mother liquor tank, the monitoring terminal can also judge whether the ratio of the mother liquor is accurate or reasonable based on the real-time EC value, PH value, and temperature in the mother liquor tank 1, and issue an alarm when the ratio of the mother liquor is unreasonable.

[0066] The mixing tank 2 is used to hold clear water and mother liquor, as well as the water fertilizer formed after the clear water and mother liquor are mixed. The mixing tank 2 obtains the clear water transported from the clear water tank 4 through the first water injection pipe 201. In other embodiments, the mixing tank 2 can also directly obtain clear water from an external water supply device, such as a faucet, through the first water injection pipe 201. The mixing tank 2 is connected to the mother liquor tank 1 through an infusion pipe 204. The water inlet of the infusion pipe 204 is communicated with the mother liquor tank 1 water pump arranged in the mother liquor tank 1, and the monitoring terminal can control the mother liquor tank 1 water pump to extract the mother liquor and transport it to the infusion pipe 204.

[0067] In this embodiment, the number of mixing tanks 2 is two, and a water fertilizer monitoring component is provided on each mixing tank 2. The monitoring terminal can switch the working mode of the corresponding mixing tank 2 between the water fertilizer mixing mode and the water fertilizer conveying mode through the water fertilizer monitoring component. The monitoring terminal can also issue an alarm when abnormal water fertilizer data appears in the water fertilizer mixing mode. The water fertilizer data specifically includes the water fertilizer liquid level, the clear water intake of the mixing tank 2, the clear water level of the mixing tank 2, and the mother liquor intake.

[0068] In the water fertilizer mixing mode, the water fertilizer monitoring component will sequentially complete the processes of clear water injection, mother liquor injection, and water fertilizer mixing in the mixing tank 2 under the control of the monitoring terminal.

[0069] After the water fertilizer mixing mode ends, the monitoring terminal can switch the working mode of the corresponding mixing tank 2 from the water fertilizer mixing mode to the water fertilizer conveying mode through the water fertilizer monitoring component.

[0070] In the water fertilizer conveying mode, the water fertilizer located in the mixing tank 2 can be transported to each crop end by the water fertilizer monitoring component under the control of the monitoring terminal to complete the irrigation operation.

[0071] Specifically, the water fertilizer monitoring component includes:

[0072] The first solenoid valve 202 is arranged on the first water injection pipe 201 and can realize the on-off of the first water injection pipe 201 under the control of the monitoring terminal.

[0073] The first flowmeter is set between the first solenoid valve 202 and the water outlet of the first water injection pipe 201. The monitoring terminal can obtain the water inflow of the mixing barrel 2 into the mixing barrel 2 after passing through the first solenoid valve 202 through it.

[0074] The second solenoid valve 205 is set on the infusion pipe 204 and can be opened and closed under the control of the monitoring terminal.

[0075] The second flowmeter is set between the second solenoid valve 205 and the water pump of the mother liquid barrel 1. The monitoring terminal can obtain the mother liquid inflow into the mixing barrel 2 through it.

[0076] The first liquid level sensor is set in the mixing barrel 2. After only injecting clean water into the mixing barrel 2, the monitoring terminal can obtain the clean water level of the mixing barrel 2 through the first liquid level sensor. After injecting clean water and mother liquid into the mixing barrel 2 successively, the monitoring terminal can obtain the water and fertilizer level through the first liquid level sensor.

[0077] The mixing barrel water pump is set in the mixing barrel 2. When it is necessary for the corresponding mixing barrel 2 to enter the water and fertilizer mixing mode, the monitoring terminal makes the corresponding mixing barrel 2 enter the water and fertilizer mixing mode by stopping the operation of the mixing barrel water pump, and then proceeds with the subsequent processes of clean water injection, mother liquid injection, and water and fertilizer mixing.

[0078] When the water and fertilizer mixing mode of the corresponding mixing barrel 2 ends and it is necessary to enter the water and fertilizer transportation mode, the monitoring terminal makes the corresponding mixing barrel 2 enter the water and fertilizer transportation mode by starting the mixing barrel water pump. At this time, the mixing barrel water pump can pump the water and fertilizer in the corresponding mixing barrel 2 and output it to each crop end to complete the irrigation operation.

[0079] The stirring pump is set in the mixing barrel 2 and can be started under the control of the monitoring terminal after the monitoring terminal confirms that the water and fertilizer data is normal to complete the mixing of clean water and mother liquid.

[0080] The mixing process of water and fertilizer is as follows:

[0081] The monitoring terminal continuously obtains the water and fertilizer levels of all mixing barrels 2 in the water and fertilizer transportation mode. When there is a mixing barrel 2 with a water and fertilizer level, the monitoring terminal controls the mixing barrel water pump in the corresponding mixing barrel 2 to stop working, so that the corresponding mixing barrel 2 switches from the water and fertilizer transportation mode to the water and fertilizer mixing mode.

[0082] The monitoring terminal controls the clean water pump to extract clean water from the clean water barrel 4 and output it to the first water injection pipe 201 and opens the first solenoid valve 202 to make the first water injection pipe 201 conductive. At the same time, the monitoring terminal continuously obtains the clean water inflow of the mixing barrel 2 entering the mixing barrel 2 through the first flowmeter. When the clean water inflow of the mixing barrel reaches the preset mixing barrel water injection value, the monitoring terminal closes the clean water pump and the first solenoid valve 202.

[0083] The monitoring terminal obtains the clear water level in the mixing barrel through the first liquid level sensor, converts it into the clear water capacity of the mixing barrel, and then calculates the difference between the clear water inflow into the mixing barrel and the clear water capacity of the mixing barrel.

[0084] If the difference between the two is greater than the preset water injection error value of the mixing barrel, the monitoring terminal outputs an alarm message or an alarm prompt sound to the management personnel to remind them.

[0085] If the difference between the two is not greater than the preset water injection error value of the mixing barrel, the monitoring terminal controls the mother liquid barrel 1 water pump to extract the mother liquid and transport it to the infusion pipe 204, and opens the second solenoid valve 205 to make the infusion pipe 204 conductive. At the same time, the monitoring terminal obtains the mother liquid inflow into the mixing barrel 2 in real time through the second flowmeter. When the mother liquid inflow reaches the preset mother liquid injection value of the mixing barrel, the monitoring terminal closes the mother liquid barrel 1 water pump and the second solenoid valve 205.

[0086] The monitoring terminal obtains the water and fertilizer level through the first liquid level sensor, subtracts the water and fertilizer level from the clear water level in the mixing barrel to obtain the theoretically increased water and fertilizer level, finally converts the theoretically increased water and fertilizer level into the newly added mother liquid volume, and finally calculates the difference between the mother liquid inflow and the newly added mother liquid volume.

[0087] If the difference between the two is greater than the preset mother liquid injection error value of the mixing barrel, the monitoring terminal outputs an alarm message or an alarm prompt sound to the management personnel to remind them.

[0088] If the difference between the two is not greater than the preset mother liquid injection error value of the mixing barrel, the monitoring terminal controls the water and fertilizer stirring pump to work to stir the clear water and the mother liquid to form water and fertilizer.

[0089] In addition, an EC sensor, a PH sensor and a water temperature sensor are also installed in the mixing barrel 2. After the water and fertilizer are stirred, the monitoring terminal can obtain the EC value, PH value and temperature of the water and fertilizer in the mixing barrel 2 through the EC sensor, the PH sensor and the water temperature sensor. When the first liquid level sensor, the first flowmeter and the second flowmeter are damaged, resulting in inaccurate water and fertilizer data, the monitoring terminal can also judge whether the ratio of water and fertilizer is accurate or reasonable according to the real-time EC value, PH value and temperature in the mixing barrel 2, and issue an alarm when the ratio of water and fertilizer is unreasonable.

[0090] In this embodiment, the water and fertilizer are formed by mixing clear water and multiple mother liquors. Generally, the concentration of the mother liquor is relatively high, while the concentration of the water and fertilizer is relatively low. The mother liquor needs to be diluted in a certain proportion, such as 1:100. Moreover, the real-time irrigation of water and fertilizer often makes the consumption rate of water and fertilizer relatively fast. Therefore, the mixing of water and fertilizer often needs to be carried out once every half an hour or one hour. The scheme of double mixing bucket switching disclosed in this embodiment enables the irrigation and mixing of water and fertilizer to be carried out simultaneously through different mixing buckets 2 by switching the working state of the mixing bucket 2, avoiding the influence on the irrigation of water and fertilizer caused by the scheme of mixing first and then irrigating.

[0091] An irrigation component for obtaining and distributing the water and fertilizer in the mixing bucket 2.

[0092] Specifically, the irrigation component includes an irrigation pipe 3, an irrigation solenoid valve 301, and an irrigation flowmeter 302 provided between the irrigation solenoid valve 301 and the outlet of the irrigation pipe 3.

[0093] When there is a mixing bucket 2 in the water and fertilizer delivery mode, the monitoring terminal controls the mixing bucket water pump to work to pump the water and fertilizer into the irrigation pipe 3 and opens the irrigation solenoid valve 301 to make the irrigation pipe 3 conduct. The irrigation pipe 3 guides the water and fertilizer to perform the water and fertilizer irrigation operation on the crops through devices such as droppers at the end of the pipeline. During this process, the monitoring terminal can obtain the amount of water and fertilizer required for one irrigation through the irrigation flowmeter 302, which is convenient for the management personnel to record and analyze the corresponding data.
