Description

Technical Field

[0001] The invention relates to the field of sluice control, and in particular to an intelligent control system for a tidal sluice. Background Art

[0002] The Yangtze River system is huge with numerous tributaries, including 3,600 navigable rivers and 437 tributaries with a basin area of ​​more than 1,000 square kilometers. A large number of sluice projects have been built on these tributaries for the purposes of regulating water flow, flood control and drainage, irrigation and water supply.

[0003] A tidal sluice is a sluice that is used to regulate the tides. Its main function is to reasonably arrange the time and amplitude of opening and closing the sluice according to the local water level and tidal conditions. However, in the process of controlling the gate height, the tidal sluice is generally intelligently regulated according to the water levels on both sides. However, in the process of regulation, the gate height vertical increase and decrease method adopted cannot effectively control the water flow in response to various complex water level changes, resulting in the need for manual observation and control of the gate during the control process. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides an intelligent control system for tidal sluices, which has the advantages of intelligently controlling the water level according to the rising and falling tides, and solves the problems in the above-mentioned background technology.

[0006] (II) Technical solution

[0007] In order to achieve the above-mentioned purpose of intelligently controlling the water level according to the rising and falling tides, the present invention provides the following technical solutions: a tidal sluice intelligent control system, comprising a water level monitoring module, a gate, a motor, a camera, a vibration monitoring module, a water volume monitoring module and a control system, wherein there are two water level monitoring modules, the gate is arranged at the intersection of the river and the river, and the camera is arranged on both sides of the sluice to respectively observe the river water surface conditions and the river water surface conditions on both sides of the sluice.

[0008] Water level monitoring module: used to monitor the water level of rivers and streams, and the water level monitoring modules are set on both sides of the gate to monitor the water level of rivers and streams on both sides of the gate respectively. The water level value monitored by the water level monitoring module on the river side is set to J, and the water level value of the water level monitoring module on the river side is set to H at the same time. At the same time, the water level monitoring module on the river side sets the river's flood season safety water level and the dry season water demand water level to W. If the set safety water level is exceeded, an alarm will be issued and feedback will be given to the control system. The frequency of the water level monitoring module transmitting numerical values ​​to the control system is 5 minutes.

[0009] Motor: The motor is installed above the gate, and the number is not less than two, which is used to control the opening and closing of the gate. The motor is connected to the control system, and the rotation time and speed of the motor are controlled by the control system.

[0010] Camera: Observe the water surface conditions of the river and the river flow on both sides of the sluice respectively to prevent the presence of ships or large floating objects in the river flow or on the river from causing damage to both sides of the gate. The camera is connected to the control system.

[0011] Vibration monitoring module: It is installed on both sides of the gate to monitor foreign objects under the water surface on both sides of the gate. It monitors the vibration value caused by the impact of foreign objects under the water surface on the gate in real time to ensure the safety of the working environment of the gate.

[0012] Water volume monitoring module: monitors the overall amount of water flowing in and out of the river or stream when the gate is opened, and the water volume monitoring module transmits the value every 5 minutes.

[0013] Preferably, the control system includes the following control steps:

[0014] S1000: The camera and water level monitoring module monitor the river water level and the river water level at the same time, and feed the monitoring data back to the control system;

[0015] S2000: When the gate needs to be intelligently controlled during the flood season, the water level monitoring module detects that the river water level exceeds the set safe water level value, that is, J>W. At this time, the control system controls the motor to control the sluice gate;

[0016] S3000: When the gate needs to be controlled in the dry season, if the monitoring data of the water level monitoring module is W≤H≤J, it means that the river water level is lower than the river water level and higher than the set safe water level, and water diversion work is required at this time.

[0017] Preferably, step S2000 also includes the following control steps:

[0018] S2100: When the values ​​J monitored by the two water level monitoring modules are greater than H, it means that the water level on the river side is lower than that on the river side, and the drainage conditions are not met. At this time, the control system controls the motor to work in reverse, driving the sluice gate to close until the sluice gate is completely closed. At the same time, the control system alarms and enters the early warning stage and notifies the river management personnel;

[0019] S2200: When the value J monitored by the two water level monitoring modules is less than H, it means that the water level on the river side is higher than the water level on the stream side, and the conditions for drainage are met. At this time, the control system controls the motor to work in the forward direction, driving the sluice gate to open, and continues to drive the sluice gate to open to half of the total gate operation stroke.

[0020] Preferably, step S2200 also includes: after the gate is opened, the water level monitoring modules on both sides of the gate continuously monitor the water levels of the river and the river, and the monitoring frequency is once every 5 minutes to determine the ratio between J and H. At this time, the monitoring values ​​of the water level monitoring modules on both sides are compared to determine whether the river water level value and the set safety water level value H are greater than W. The control system controls the opening and closing of the motor and the gate according to the ratio of H to W.

[0021] Preferably, the step S2200 also includes the following specific control method:

[0022] S2201: If the ratio of the feedback data from the river side water level monitoring module to the safety water level data is H>W after 5 minutes, it means that the river side water level is still greater than the set safety water level. At this time, the gates are opened in stages, and the gates are raised by 0.5m through the motor. The water level monitoring module is used to continuously monitor and control the river water level and the river water level on both sides of the gates.

[0023] S2202: If after 5 minutes, the ratio of the feedback data from the water level monitoring module on the river side to the safe water level data is H<W, it means that the water level on the river side is lower than the set safe water level. At this time, the gates are closed in stages, and the motor is used to lower the gates by 0.5m. The water level monitoring module is used to continuously monitor the river water level and the river water level on both sides of the gates, and the cycle is repeated every 5 minutes until the river water level is equal to the river water level, that is, H≥J, and then the gates are completely closed.

[0024] Preferably, the step S3000 also includes the following specific control method:

[0025] S3100: The water level monitoring module detects that W≤H≤J. Since the river water level is higher than the river water level, it means that the water diversion conditions are met. At this time, the control system controls the motor to rotate forward and controls the gate to open to half of the total stroke;

[0026] S3200: At this time, the water level monitoring module starts to monitor the ratio of the river water level to the river flow water level and transmits it to the control system, and the control system controls the motor.

[0027] Preferably, the step S3200 further includes the following specific control steps:

[0028] S3210: After the gate is half-opened, if the water level monitoring module detects H≥J during another monitoring 5 minutes later, it means that the river water level is already the same as the river flow water level and the water diversion conditions are no longer met. At this time, the control system controls the motor to reverse and controls the gate to descend until it is completely closed;

[0029] S3220: After the gate is half opened, if the water level monitoring module detects that H<J during another monitoring 5 minutes later, it means that the river water level is still greater than the river water level. At this time, the gate is controlled based on the ratio of the river water level to the set safety water level.

[0030] Preferably, the step S3220 also includes the following specific control steps:

[0031] S3221: At this time, if the data transmitted by the water level monitoring module is H>W, it means that the river water level has exceeded the set control water level, indicating that the river water level has reached the set safety water level. At this time, the control system controls the motor to reverse, and the gate drops by 0.5m, and the gate is closed in stages. After 5 minutes, it is controlled again according to the data transmitted by the water level monitoring module;

[0032] S3222: At this time, if the data transmitted by the water level monitoring module is H≤W, it means that there is still redundancy between the river water level and the set safe water level. At this time, the control system controls the motor to rotate forward, and the gate rises by 0.5m, and the gate is opened in stages. After 5 minutes, the water level monitoring module transmits data again, and the gate is controlled according to the transmitted data.

[0033] (III) Beneficial effects

[0034] Compared with the prior art, the present invention provides an intelligent control system for tidal sluice gates, which has the following beneficial effects:

[0035] The overall control system can eliminate the fixed water level in the conventional fixed water level monitoring and control, and control the water level of the entire river according to the tidal direction of the river. The overall control system is more intelligent, and can achieve the opening and closing and adjustment of the sluice gates intelligently according to the tidal water level of the river in different periods, saving a lot of human resources. It can also ensure the safety of the entire river and the surrounding irrigation and water use during the flood season and the dry season, making the control method that combines tidal control with flood and dry season control. In the later use process, it can perform intelligent comprehensive adjustment according to the water levels of different tides and the water levels of the flood and dry seasons.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example 1

[0040] A preferred embodiment of the tidal sluice intelligent control system provided by the present invention is as follows: Figure 1 As shown: an intelligent control system for a tidal sluice, including a water level monitoring module, a gate, a motor, a camera, a vibration monitoring module, a water volume monitoring module and a control system. There are two water level monitoring modules. The gate is arranged at the intersection of a river and a stream. The camera is arranged on both sides of the sluice to observe the water surface conditions of the river and the stream on both sides of the sluice respectively.

[0041] Water level monitoring module: used to monitor the water level of rivers and streams, and the water level monitoring modules are set on both sides of the gate to monitor the water level of rivers and streams on both sides of the gate respectively. The water level value monitored by the water level monitoring module on the river side is set to J, and the water level value of the water level monitoring module on the river side is set to H at the same time. At the same time, the water level monitoring module on the river side sets the river's flood season safety water level and the dry season water demand water level to W. If the set safety water level is exceeded, an alarm will be issued and feedback will be given to the control system. The frequency of the water level monitoring module transmitting numerical values ​​to the control system is 5 minutes.

[0042] Motor: The motor is installed above the gate, and the number is not less than two, which is used to control the opening and closing of the gate. The motor is connected to the control system, and the rotation time and speed of the motor are controlled by the control system.

[0043] Camera: Observe the water surface conditions of the river and the river flow on both sides of the sluice respectively to prevent the presence of ships or large floating objects in the river flow or on the river from causing damage to both sides of the gate. The camera is connected to the control system.

[0044] Vibration monitoring module: It is installed on both sides of the gate to monitor foreign objects under the water surface on both sides of the gate. It monitors the vibration value caused by the impact of foreign objects under the water surface on the gate in real time to ensure the safety of the working environment of the gate.

[0045] Water volume monitoring module: monitors the overall amount of water flowing in and out of the river or stream when the gate is opened, and the water volume monitoring module transmits the value every 5 minutes. At the same time, the water volume monitoring module can also monitor the flow rate of the water.

[0046] Example 2

[0047] Based on Example 1, a preferred embodiment of the tidal sluice intelligent control system provided by the present invention is as follows: Figure 1 to Figure 2 As shown: It includes the following control steps:

[0048] S1000: The camera and water level monitoring module monitor the river water level and the river water level at the same time, and feed the monitoring data back to the control system;

[0049] S2000: When the gate needs to be intelligently controlled during the flood season, the water level monitoring module detects that the river water level exceeds the set safe water level value, that is, J>W. At this time, the control system controls the motor to control the sluice gate. Specifically:

[0050] S2100: When the values ​​J monitored by the two water level monitoring modules are greater than H, it means that the water level on the river side is higher than that on the river side, and the drainage conditions are not met. At this time, the control system controls the motor to work in reverse, driving the sluice gate to close until the sluice gate is completely closed. At the same time, the control system alarms and enters the early warning stage and notifies the river management personnel;

[0051] S2200: When the values ​​J monitored by the two water level monitoring modules are less than H, it means that the water level on the river side is higher than that on the river side, and the drainage conditions are met. At this time, the control system controls the motor to work in the forward direction, driving the sluice gate to open, and driving the sluice gate to open to half of the total gate operation stroke. Specifically:

[0052] After the gate is opened, the water level monitoring modules on both sides of the gate continuously monitor the water level of the river and the river. The monitoring frequency is once every 5 minutes to determine the ratio between J and H. At this time, the monitoring values ​​of the water level monitoring modules on both sides are compared to determine whether the river water level value and the set safe water level value H are greater than W. The control system controls the opening and closing of the motor and the gate according to the ratio of H to W, which specifically includes the following control steps:

[0053] S2201: If the ratio of the feedback data from the river side water level monitoring module to the safety water level data is H>W after 5 minutes, it means that the river side water level is still greater than the set safety water level. At this time, the gates are opened in stages, and the gates are raised in stages through the motor. The water level monitoring module is used to continuously monitor and control the river water level and the river water level on both sides of the gates.

[0054] Furthermore, the gate can be raised and lowered in stages according to the following formula:

[0055]

[0056] in:

[0057] Δ=±(Y J -Y H )

[0058] S: gate area;

[0059] L: water flow velocity;

[0060] Δ: the water level difference between the river and the stream;

[0061] μ: unit mediation coefficient;

[0062] Y J : river water level;

[0063] Y H : River surface water level.

[0064] Furthermore, the water level difference on both sides of the gate is added through the ratio of the water flow velocity and the area of ​​the gate, and the height of each stage of the gate lifting and lowering is calculated through the water level difference. When the water level difference Δ on both sides of the gate is larger, the height of each stage of the gate lifting and lowering is higher. Conversely, when the water level difference Δ on both sides of the gate is smaller, the height of each stage of the gate lifting and lowering is smaller.

[0065] Furthermore, the effect of the change in the river side water level on the height of the gate lift can be derived using the following formula:

[0066]

[0067] in,

[0068] JΔ: difference in water level change in river flow;

[0069] HΔ: Gate height change value.

[0070] When draining or diverting water, the water level monitoring module monitors the water level on the river side every 5 minutes, calculates the difference between the water level values ​​on the adjacent two sides, and controls the height increase of the gate level by the difference change of the river water level. At this time, if the river water level JΔ changes more, the gate needs to increase the height HΔ more, and vice versa, the smaller the river water level JΔ changes, the gate needs to increase the height HΔ less, and the gate height that needs to change is deduced from the change of the river water level. At this time, when draining or diverting water, the change factor of the river water level can be brought into the process of each gate opening or closing for real-time regulation.

[0071] S2201a: 5 minutes later, the water level monitoring module transmits the water level data between the river and the river again. If H>J and H>W, it means that the water level on the river side is still redundant with the river level and the water level on the river side has not reached the set safe water level, then step S2111 is performed again to continue the drainage work;

[0072] S2201b: If H≤J, it means that the water level of the river surface is lower than the water level of the river flow or is flush with the water level of the river flow. At this time, it means that the water level of the river cannot be lowered again. The control system controls the motor and the gate to close the gate until the gate is completely closed;

[0073] S2201c: 5 minutes later, the water level monitoring module transmits the water level data between the river and the river again. If H>J and H<W, it means that the water level on the river side is still redundant with the river water level, but the water level on the river side is lower than the set safety water level, then the gates are closed in stages. At this time, the control system controls the motor and the gate to descend in stages. The water level monitoring module feeds back data again after 5 minutes. If the river water level is still greater than the river water level and less than the set safety water level, the cycle is performed until the river water level H≤J river water level. At this time, the cycle runs step S2111b;

[0074] S2202: If the ratio of the feedback data from the water level monitoring module on the river side to the safe water level data is H<W after 5 minutes, it means that the water level on the river side is lower than the set safe water level. At this time, the gates are closed in stages, and the gates are lowered by the motor. The water level monitoring module continuously monitors the river water level and the river water level on both sides of the gates, once every 5 minutes, until the river water level is equal to the river water level, that is, H≥J, and then the gates are completely closed;

[0075] S3000: When the gate needs to be controlled in the dry season, if the monitoring data of the water level monitoring module is W≤H≤J, it means that the river water level is lower than the river water level and higher than the set safe water level. At this time, water diversion work is required. Specifically:

[0076] S3100: The water level monitoring module detects that W≤H≤J. Since the river water level is higher than the river water level, it means that the water diversion conditions are met. At this time, the control system controls the motor to rotate forward and controls the gate to open to half of the total stroke;

[0077] S3200: At this time, the water level monitoring module starts to monitor the ratio of the river water level to the river flow water level and transmits it to the control system, which controls the motor. Specifically:

[0078] S3210: After the gate is half-opened, if the water level monitoring module detects H≥J during another monitoring 5 minutes later, it means that the river water level is already the same as the river flow water level and the water diversion conditions are no longer met. At this time, the control system controls the motor to reverse and controls the gate to descend until it is completely closed;

[0079] S3220: After the gate is halfway opened, if the water level monitoring module detects H<J during another monitoring 5 minutes later, it means that the river water level is still greater than the river water level. At this time, the gate is controlled according to the ratio of the river water level to the set safety water level. Specifically:

[0080] S3221: At this time, if the data transmitted by the water level monitoring module is H>W, it means that the river water level has exceeded the set control water level, indicating that the river water level has reached the set safety water level. At this time, the control system controls the motor to reverse, and the gate is closed in stages. After 5 minutes, it is controlled again according to the data transmitted by the water level monitoring module. Specifically:

[0081] S3221a: If the feedback data from the water level monitoring module is still H<J and H>W after 5 minutes, it means that the river water level is lower than the river water level and the river water level is higher than the control water level. At this time, it is necessary to close the gate again in different levels, and the loop step S3221 is performed;

[0082] S3221b: If the water level monitoring module feedback data is H≥J after 5 minutes, it means that the river water level is equal to the river flow water level, indicating that water can no longer be diverted, and the gate is completely closed. At this time, the control system controls the motor to reverse and the gate drops until the gate is completely closed;

[0083] S3222: If the data transmitted by the water level monitoring module is H≤W, it means that there is still redundancy between the river water level and the set safe water level. At this time, the control system controls the motor to rotate forward, the gate rises, and the gate is opened in stages. After 5 minutes, the water level monitoring module transmits data again. At this time, the gate is controlled according to the transmitted data. Specifically:

[0084] S3222a: If the water level monitoring module detects data of H<J and H>W after 5 minutes, it means that the river water level is lower than the river water level and higher than the set safe water level. At this time, the control system loops S3221a.

[0085] S3222b: If the water level monitoring module detects that the data is H≥J after 5 minutes, it means that the river water level is equal to the river water level and the water diversion conditions are no longer met. The control system controls the motor to reverse and the gate to descend until the gate is completely closed;

[0086] S3222c: If after 5 minutes the water level monitoring module detects data of H<J and H<W, it means that the water surface of the river is lower than the water surface of the stream and is lower than the set safe water level. The river water level still has redundant space for water diversion. At this time, the control system loops step S3222.

[0087] After the above control steps are controlled, the overall control system can eliminate the conventional fixed water level monitoring control and follow the tidal direction of the river to control the water level of the entire river. The overall control system is more intelligent, saving a lot of human resources, and can ensure the safety of the entire river and the surrounding irrigation and water use during the flood season and the dry season.

[0088] Example 3

[0089] The technology of Example 2 also includes opening and closing and regulating the gate according to the discharge volume, specifically:

[0090] When drainage work with a fixed amount of water is required, the time period is 5 minutes, including the following control steps:

[0091] T10: When water volume control is required, the required water volume for inlet and outlet of the water volume monitoring module is set to D. The control system controls the motor to rotate forward, and the motor drives the gate to fully open.

[0092] T20: After the gate is fully opened, the water level monitoring module starts to monitor the water levels on both sides and sets the quantitative discharge water volume to be equal to the water level difference between the river side and the river side of 1m, and the water level monitoring module is recorded as C. At this time, the control system controls the opening and closing of the gate according to the value of C. Specifically:

[0093] T21: If the value transmitted by the water level monitoring module is ≥C after the gate is fully opened for 5 minutes, it means that the water level difference is greater than or equal to 1m. At this time, it means that the water level difference is still too large and it is necessary to continue to release water. At this time, the control system controls the motor to rotate forward and the gate is closed in stages;

[0094] Furthermore, the height of the graded gate of the discharge volume can be calculated according to the following derivation formula:

[0095]

[0096] in:

[0097] D: volume of water to be discharged;

[0098] Δ: Water level difference.

[0099] Furthermore, when the value of Δ is greater than 1, the closing height of the sluice gate is calculated by the formula. When the value of Δ is larger, it means that the water level difference is still too large. The smaller the value of H2 is derived from the formula, the smaller the gate's graded closing distance is. On the contrary, when the value of Δ is smaller, it means that the water level difference has decreased. The larger the value of H2 is derived from the formula, the larger the gate's graded closing distance is.

[0100] T22: If the value transmitted by the water level monitoring module is <C after the gate is fully opened for 5 minutes, it means that the water level difference is less than 1m, which means that the water level difference is qualified and the discharged or discharged water volume has reached the standard. At this time, the control system controls the gate to be completely closed.

[0101] In addition to the above-mentioned gate control steps, in addition to the gate being controlled by the control system and the motor, the gate vibration detection step is also included:

[0102] Specifically, when the gate is rising or falling, the vibration value generated by the gate is fed back to the vibration monitoring module. The vibration monitoring module sets the safe vibration frequency generated by the gate directly closing or opening as α1, and the vibration frequency of the gate being graded and raised by the control system and the motor as α2. The vibration generated when the gate is opened or closed is used to judge the state of the gate:

[0103] When the system controls the gate to fully rise or fully lower, if the vibration value generated is greater than α1, it means that the gate vibration value has exceeded the safe vibration range. At this time, the control system will alarm and notify the staff to check the aging or impact problems of the gate components. At the same time, the control system controls the water volume monitoring module to recalculate the water supply and drainage at the gate. If the drainage volume increases too much, it means that the gate is broken or the gate is off the track. At this time, an alarm will be issued and the staff will be notified to handle the emergency.

[0104] When the system controls the gate to perform graded lifting and lowering, if the vibration value generated is greater than α2, it means that the gate vibration value has exceeded the safe vibration range. At this time, the control system will alarm and notify the staff to inspect the gate and floating objects in the river to eliminate the safety hazards caused by floating objects to the gate.

[0105] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0106] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

At this time, the control system controls the motor to control the sluice gate; S3000: When the gate needs to be controlled in the dry season, if the monitoring data of the water level monitoring module is W≤H≤J, it means that the river water level is lower than the river water level and higher than the set safe water level, and water diversion work is required at this time.

3. The intelligent control system for tidal sluice gate according to claim 2, characterized in that: The step S2000 also includes the following control steps: S2100: When the values ​​J monitored by the two water level monitoring modules are greater than H, it means that the water level on the river side is lower than that on the river side, and the drainage conditions are not met. At this time, the control system controls the motor to work in reverse, driving the sluice gate to close until the sluice gate is completely closed. At the same time, the control system alarms and enters the early warning stage and notifies the river management personnel; S2200: When the value J monitored by the two water level monitoring modules is less than H, it means that the water level on the river side is higher than the water level on the stream side, and the conditions for drainage are met. At this time, the control system controls the motor to work in the forward direction, driving the sluice gate to open, and continues to drive the sluice gate to open to half of the total gate operation stroke.

4. The intelligent control system for tidal sluice gate according to claim 3 is characterized by: The step S2200 also includes: after the gate is opened, the water level monitoring modules on both sides of the gate continuously monitor the water levels of the river and the stream, and the monitoring frequency is once every 5 minutes to determine the ratio between J and H. At this time, the monitoring values ​​of the water level monitoring modules on both sides are compared to determine whether the river water level value and the set safety water level value H are greater than W. The control system controls the opening and closing of the motor and the gate according to the ratio of H to W.

5. The intelligent control system for tidal sluice gate according to claim 4, characterized in that: The step S2200 also includes the following specific control method: S2201: If the ratio of the feedback data from the river side water level monitoring module to the safety water level data is H>W after 5 minutes, it means that the river side water level is still greater than the set safety water level. At this time, the gates are opened in stages, and the gates are raised by 0.5m through the motor. The water level monitoring module is used to continuously monitor and control the river water level and the river water level on both sides of the gates. S2202: If after 5 minutes, the ratio of the feedback data from the water level monitoring module on the river side to the safe water level data is H<W, it means that the water level on the river side is lower than the set safe water level. At this time, the gates are closed in stages, and the motor is used to lower the gates by 0.5m. The water level monitoring module is used to continuously monitor the river water level and the river water level on both sides of the gates, and the cycle is repeated every 5 minutes until the river water level is equal to the river water level, that is, H≥J, and then the gates are completely closed.

6. The intelligent control system for tidal sluice gate according to claim 5, characterized in that: The step S3000 also includes the following specific control method: S3100: The water level monitoring module detects that W≤H≤J. Since the river water level is higher than the river water level, it means that the water diversion conditions are met. At this time, the control system controls the motor to rotate forward and controls the gate to open to half of the total stroke; S3200: At this time, the water level monitoring module starts to monitor the ratio of the river water level to the river flow water level and transmits it to the control system, and the control system controls the motor.

7. The intelligent control system for tidal sluice gate according to claim 6, characterized in that: The step S3200 also includes the following specific control steps: S3210: After the gate is half-opened, if the water level monitoring module detects H≥J during another monitoring 5 minutes later, it means that the river water level is already the same as the river flow water level and the water diversion conditions are no longer met. At this time, the control system controls the motor to reverse and controls the gate to descend until it is completely closed; S3220: After the gate is half opened, if the water level monitoring module detects that H<J during another monitoring 5 minutes later, it means that the river water level is still greater than the river water level. At this time, the gate is controlled based on the ratio of the river water level to the set safety water level.

8. The intelligent control system for tidal sluice gate according to claim 7, characterized in that: The step S3220 also includes the following specific control steps: S3221: At this time, if the data transmitted by the water level monitoring module is H>W, it means that the river water level has exceeded the set control water level, indicating that the river water level has reached the set safety water level. At this time, the control system controls the motor to reverse, and the gate drops by 0.5m, and the gate is closed in stages. After 5 minutes, it is controlled again according to the data transmitted by the water level monitoring module; S3222: At this time, if the data transmitted by the water level monitoring module is H≤W, it means that there is still redundancy between the river water level and the set safe water level. At this time, the control system controls the motor to rotate forward, and the gate rises by 0.5m, and the gate is opened in stages. After 5 minutes, the water level monitoring module transmits data again, and the gate is controlled according to the transmitted data.

9. The intelligent control system for tidal sluice gate according to claim 5, characterized in that: The step S2201 further includes: If the ratio of the feedback data from the water level monitoring module on the river side to the safe water level data is H>W after 5 minutes, it means that the water level on the river side is still greater than the set safe water level. At this time, the gates are opened in stages, and the gates are raised in stages through the motor. The water level monitoring module is used to continuously monitor and control the river water level and the river water level on both sides of the gates. Furthermore, the gate can be raised and lowered in stages according to the following formula: in: Δ=±(Y J -AND H ) S: gate area; L: water flow velocity; Δ: the water level difference between the river and the stream; μ: unit mediation coefficient; Y J : river water level; Y H : River surface water level. Furthermore, the water level difference on both sides of the gate is added through the ratio of the water flow velocity and the area of ​​the gate, and the height of each stage of the gate lifting and lowering is calculated through the water level difference. When the water level difference Δ on both sides of the gate is larger, the height of each stage of the gate lifting and lowering is higher. Conversely, when the water level difference Δ on both sides of the gate is smaller, the height of each stage of the gate lifting and lowering is smaller. Furthermore, the effect of the change in the river side water level on the height of the gate lift can be derived using the following formula: in, JΔ: difference in water level change in river flow; HΔ: Gate height change value. During the process of drainage or water diversion, the water level monitoring module monitors the water level on the river side every 5 minutes, calculates the difference between the water level values ​​on the adjacent two sides, and the height of the gate is raised in stages according to the difference in the measured water level of the river to control the increase in the height of the rise and fall. At this time, if the measured water level JΔ of the river changes more, the height HΔ of the gate needs to be increased more, and vice versa, the smaller the change in the measured water level JΔ of the river changes, the smaller the height HΔ of the gate needs to be increased.
