[0026] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than 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.

[0027] The integrated gate is an automated gate control system with the gate remote control terminal as its core. Combined with channel flow measurement theory and sensor measurement technology, it can realize remote control and flow monitoring of the gate. The system responds to control commands issued by the remote server to adjust and control the gate opening. The integrated measurement and control gate is designed for open channel irrigation, from water conservancy hubs to water diversion channels and then to drainage ditches, to achieve unmanned, automated and intelligent water flow control in the entire river basin.

[0028] Embodiment 1: Figure 1As shown, the intelligent control system adapted to the intelligent control integrated gate system includes an opening test module, a water level monitoring module, an opening verification module, a controller and a storage module. The opening test module, the storage module and the water level monitoring module are communicatively connected in sequence. The opening test module, the storage module and the water level monitoring module are all communicatively connected with the controller, and the opening verification module is communicatively connected with the water level monitoring module and the storage module.

[0029] The opening test module is used to perform opening test analysis on the integrated gate: generate a test cycle, and when the upstream water level of the integrated gate is higher than the water level threshold during the test cycle, mark the upstream water level as the test water level, generate a gate opening signal and send the test gate opening signal to the controller. After receiving the test gate opening signal, the controller randomly assigns an opening value to the integrated gate and marks it as the test opening, sets the opening of the integrated gate to the test opening, and then generates a test period of L1 minutes. At the beginning of the test period, the integrated gate is imaged and marked as the gate opening image of the test opening; at the end of the test period, the flow data LL, vibration data ZD and noise data ZS within the test period are obtained. The flow data LL is the maximum water flow of the integrated gate during the test period, the vibration data ZD is the maximum vibration amplitude of the guide rail of the integrated gate during the test period, and the noise data ZS is the maximum noise decibel generated by the operation of the integrated gate during the test period; through the formula YX = (w1×LL) / (w2×ZD+w3×ZS) The operating coefficient YX of the test opening is obtained. The operating coefficient YX is a value that reflects the stability of the operating state of the integrated gate during the test period. The larger the value of the operating coefficient YX, the higher the stability of the operating state of the integrated gate during the test period. Among them, w1, w2 and w3 are all proportional coefficients, and w1>w2>w3>1. The water level range is composed of the maximum and minimum values ​​of the test water level in the test cycle, and the water level range is divided into several water level intervals. The test opening corresponding to the maximum value of the operating coefficient YX in the test period when the test water level is within the water level interval is marked as the allocated opening of the water level interval; a water level-opening comparison table is generated from all water level intervals and the corresponding allocated openings; the water level-opening comparison table and the gate opening image corresponding to the allocated opening are sent to the storage module for storage; the gate state parameters of the test period corresponding to the test opening randomly assigned in the test cycle are collected and analyzed to obtain the operating coefficient. The water level-opening comparison table generated according to the operating coefficient, the test opening and the test water level can provide data support for the gate opening control.

[0030] The water level monitoring module is used to monitor and analyze the water level of the integrated gate: generate a monitoring cycle and divide the monitoring cycle into several monitoring time periods, obtain the upstream water level of the integrated gate at the end of the monitoring time period and mark it as the water level monitoring value, and compare the water level monitoring value with the water level threshold: if the water level monitoring value is less than or equal to the water level threshold, it is determined that the upstream water level meets the requirements; if the water level monitoring value is greater than the water level threshold, it is determined that the upstream water level does not meet the requirements, generate a water level gate opening signal and send the water level gate opening signal to the controller. After receiving the water level gate opening signal, the controller retrieves the water level-opening comparison table through the storage module, marks the allocated opening corresponding to the water level interval to which the water level monitoring value belongs as the opening control value, controls the opening of the integrated gate through the opening control value, and then takes an image of the integrated gate and marks it as a verification image of the opening control value, and sends the verification image to the opening verification module; when the upstream water level does not meet the requirements, the corresponding allocated opening is directly retrieved through the water level-opening comparison table, so that the gate opening is controlled according to the allocated opening to ensure the operation stability when the gate is open.

[0031] The opening verification module is used to verify and analyze the opening control state of the integrated gate: the gate opening image corresponding to the opening control value is retrieved through the storage module, the gate opening image and the verification image are marked as comparison images, and the two comparison images are compared and analyzed: the comparison image is enlarged into a pixel grid image and grayscale transformation is performed, the gate area and the guide rail area in the comparison image are segmented by the binary method, the top ends of the two guide rails are connected to obtain the top tangent line, and the closed area formed by the top edge of the gate, the inner edges of the two guide rails and the top tangent line in the comparison image is marked as the comparison area, the number of pixels in the comparison area is marked as the comparison value of the comparison image, the absolute value of the difference between the comparison values ​​of the two comparison areas is marked as the comparison difference data, and the comparison difference data is The ratio of the comparison value corresponding to the gate opening image as the comparison image is marked as the ratio difference coefficient. The ratio difference threshold is obtained through the storage module, and the ratio difference coefficient is compared with the ratio difference threshold: if the ratio difference coefficient is less than the ratio difference threshold, it is determined that the opening control state of the integrated gate meets the requirements; if the ratio difference coefficient is greater than or equal to the ratio difference threshold, it is determined that the opening vacant state of the integrated gate does not meet the requirements, and a control optimization signal is generated and sent to the mobile phone terminal of the manager; after long-term use, the opening control accuracy of the gate will be affected by many factors. The opening control accuracy of the integrated gate is evaluated by comparing and analyzing the comparison images, and timely warning is given when the opening control state is abnormal to ensure the subsequent gate opening control accuracy.

[0032] Embodiment 2: Figure 2 As shown, the intelligent control method adapted to the intelligent control integrated gate system includes the following steps:

[0033] Step 1: Perform opening test analysis on the integrated gate: generate a test cycle, mark the upstream water level as the test water level when the upstream water level of the integrated gate is higher than the water level threshold during the test cycle, generate a gate opening signal and send the test gate opening signal to the controller;

[0034] Step 2: Generate a test period of L1 minutes, take an image of the integrated gate at the beginning of the test period and mark it as the gate opening image of the test opening; obtain the operation coefficient YX at the end of the test period, and generate a water level-opening comparison table through the operation coefficient YX;

[0035] Step 3: Perform water level monitoring and analysis on the integrated gate: Generate a monitoring cycle and divide the monitoring cycle into several monitoring periods. At the end of the monitoring period, obtain the upstream water level of the integrated gate and mark it as the water level monitoring value. When the water level monitoring value is greater than the water level threshold, retrieve the opening control value through the water level-opening comparison table to perform gate opening control.

[0036] Step 4: Verify and analyze the opening control status of the integrated gate: retrieve the gate opening image corresponding to the opening control value through the storage module, mark the gate opening image and the verification image as comparison images, compare the two comparison images to obtain the difference coefficient, and determine whether the opening control status of the integrated gate meets the requirements through the difference coefficient.

[0037] The intelligent control system adapted to the intelligent control integrated gate system generates a test cycle when working. When the upstream water level of the integrated gate is higher than the water level threshold during the test cycle, the upstream water level is marked as the test water level, a gate opening signal is generated and the test gate opening signal is sent to the controller; a test period of L1 minutes is generated, and an image of the integrated gate is taken at the beginning of the test period and marked as a gate opening image of the test opening; an operation coefficient YX is obtained at the end of the test period, and a water level-opening comparison table is generated through the operation coefficient YX; a monitoring cycle is generated and divided into several monitoring periods, and the upstream water level of the integrated gate is obtained at the end of the monitoring period and marked as a water level monitoring value, and when the water level monitoring value is greater than the water level threshold, the opening control value is retrieved through the water level-opening comparison table for gate opening control; the gate opening image corresponding to the opening control value is retrieved through the storage module, the gate opening image and the verification image are marked as comparison images, the two comparison images are compared to obtain a difference coefficient, and whether the opening control state of the integrated gate meets the requirements is determined by the difference coefficient.

[0039] The above formulas are obtained by collecting a large amount of data for software simulation and selecting a formula close to the real value. The coefficients in the formula are set by technicians in this field according to the actual situation; for example: formula YX = (w1×LL) / (w2×ZD+w3×ZS); technicians in this field collect multiple groups of sample data and set corresponding operating coefficients for each group of sample data; substitute the set operating coefficients and the collected sample data into the formula, any three formulas constitute a three-variable linear equation group, screen the calculated coefficients and take the average, and obtain the values ​​of w1, w2 and w3 as 3.54, 2.83 and 2.19 respectively;

[0040] The size of the coefficient is to quantify each parameter to obtain a specific value for subsequent comparison. The size of the coefficient depends on the amount of sample data and the initial setting of the corresponding operating coefficient for each set of sample data by technical personnel in this field; as long as it does not affect the proportional relationship between the parameter and the quantified value, such as the operating coefficient is proportional to the value of the flow data.
