[0029] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0030] In one embodiment, Figure 1 As shown, an intelligent control drainage system based on ecological ditch water treatment is provided, including: a prefabricated resin concrete linear drainage ditch system, an intelligent control valve, an AI camera, real-time traffic situation data access software, a control box, an intelligent control platform and an ecological ditch;

[0031] The intelligent control valve is installed at the direct discharge outlet of the drainage ditch system. The intelligent control valve is used to open or close the direct discharge outlet of the drainage ditch system; the AI ​​camera is installed above the drainage ditch of the drainage ditch system. The AI ​​camera is used to collect images of the drainage ditch to determine the water flow and water quality of the drainage ditch; the ecological ditch is connected to the sewage outlet of the drainage ditch system. The ecological ditch is used to purify the sewage discharged from the sewage outlet of the drainage ditch system before discharging it; the control box is connected to the intelligent control valve, the sensor of the drainage ditch system, and the intelligent control platform network. The intelligent control platform exchanges data with the intelligent control valve and the sensor of the drainage ditch system through the control box; The AI ​​camera and real-time traffic situation data access software are connected to the intelligent control platform network; the intelligent control platform obtains the drainage ditch images collected by the AI ​​camera, the pH value data collected by the sensor and the traffic conditions of the real-time traffic situation data access software, and analyzes whether the water currently flowing into the drainage ditch is sewage or initial rain according to the drainage ditch images, pH value data and traffic conditions. When the water in the drainage ditch is sewage or initial rain and the intelligent control valve is open, a command to close the intelligent control valve is sent to the control box, so that the control box controls the intelligent control valve to close, thereby allowing the water in the drainage ditch to be discharged from the sewage outlet into the ecological ditch to complete the purification treatment.

[0032] Among them, the drainage ditch system adopts a prefabricated design and is made of resin concrete material. The internal structure of the drainage ditch system is smooth, the friction coefficient is small, and the drainage flow rate is 4-5 times that of ordinary concrete drainage ditches, which improves the drainage efficiency, reduces drainage blockage and water accumulation, and can effectively reduce the accumulation of sludge and debris. The drainage ditch system is easy to install and can be seamlessly connected with the bridge deck to ensure smooth drainage. The design of the drainage ditch of the drainage ditch system follows the drainage requirements of the bridge deck to ensure unobstructed water flow and avoid water accumulation.

[0033] Among them, the intelligent control valve is installed at the direct discharge outlet of the drainage ditch system, which can automatically adjust the opening / closing according to the drainage conditions to realize intelligent control.

[0034] The control box is used to manage the power supply and data communication of the sensors of the intelligent control valve, emergency button, and drainage ditch system. The control box is connected to the public network through 4G or wired network, and exchanges data with the intelligent control platform. The control box transmits data bidirectionally with the intelligent control valve and emergency button bound to it through the local area network, and the longest point-to-point distance can reach 16 kilometers.

[0035] Among them, the sensor of the drainage ditch system is a sensor for detecting the pH value of water.

[0036] Among them, AI cameras are used to monitor the flow and water quality of drainage ditches in real time. Through image recognition technology, it can intelligently identify different situations such as initial rain, sewage, and rainwater after initial rain, providing accurate decision-making basis for the intelligent drainage system.

[0037] Among them, real-time traffic situation data access software (such as map software) is a software tool specifically used to obtain, process and display real-time traffic data. The real-time traffic situation data access software captures road vehicle images through real-time image analysis, and obtains the actual coordinates of the vehicle on the road through the reverse perspective mapping algorithm based on the three-dimensional coordinates of the camera that captures the road vehicle image and the actual position and length of the road in the image. By comparing historical data, the moving speed of the vehicle is analyzed. When the vehicle's stationary time exceeds a certain threshold, the vehicle and its position are marked, and the vehicle abnormality alarm information is sent to the front end to notify the intelligent platform to adopt an emergency processing mechanism.

[0038] Among them, the intelligent control platform is the core of the entire intelligent drainage system based on ecological ditch water treatment. It is responsible for receiving, processing and analyzing various data, and issuing corresponding control instructions based on the analysis results. The platform adopts remote wireless control mode to realize the intelligent and automated management of the drainage system.

[0039] In one example, the system architecture of the intelligent control platform is as follows: Figure 2As shown, the intelligent control platform is responsible for receiving, processing and analyzing various data through the cloud server. Users can access the cloud server through the Web front-end and mobile phone APP based on wired or wireless Http protocol. The cloud server transmits data with the AI ​​camera based on the 4GHttp protocol. The cloud server communicates with the intelligent valve Lora through the intelligent valve gateway based on the 4G TCP protocol to automatically manage the intelligent valve.

[0040] In one example, the execution logic of the intelligent control platform is as follows: Figure 3 As shown, through Figure 3 The execution logic of the intelligent control platform shown realizes the intelligent and automated management of the drainage system.

[0041] Among them, the construction of ecological ditches makes full use of the space under the bridge. By transforming the original ditches, widening and deepening the drainage channels, an ecosystem with strong purification capabilities is formed. Plants with adsorption and purification capabilities, such as submerged plants and emergent plants, are planted in the ecological ditches. These plants can not only absorb pollutants in the water, but also provide a living environment for microorganisms and promote the degradation of microorganisms. Beneficial animal and microbial populations are also introduced, such as aquatic organisms such as fish and shellfish, as well as microbial flora specifically used to degrade oil and organic matter. These organisms and microorganisms work together in the ecological ditches to further improve the water purification effect.

[0042] It should be understood that the drainage ditch system and the ecological ditch are connected through pipe trenches to achieve the coordinated work of drainage and water treatment. The intelligent control platform adjusts the opening and closing degree of the drainage ditch and the discharge strategy in real time according to the monitoring data of the AI ​​camera, the pH value data collected by the sensor, and the traffic conditions of the real-time traffic situation data access software to ensure that no discharge is made before the initial rain and sewage purification meet the standards. At the same time, as an extension and supplement to the drainage system, the ecological ditch further purifies and absorbs the rainwater that has been preliminarily treated to improve the water quality. The drainage ditch uses resin concrete materials and the ecological ditch to purify the sewage. The whole process uses materials and energy-saving technologies to reduce energy consumption. At the same time, the application of the ecological ditch reduces the negative impact on the environment.

[0043] The above-mentioned intelligent control drainage system based on ecological ditch water treatment is installed at the direct discharge outlet of the drainage ditch system through the intelligent control valve, and the intelligent control valve is used to open or close the direct discharge outlet of the drainage ditch system; the AI ​​camera is installed above the drainage ditch of the drainage ditch system, and the AI ​​camera is used to collect drainage ditch images to determine the water flow and water quality of the drainage ditch; the ecological ditch is connected to the sewage outlet of the drainage ditch system, and the ecological ditch is used to purify the sewage discharged from the sewage outlet of the drainage ditch system before discharging; the control box is connected to the intelligent control valve, the sensor of the drainage ditch system, and the intelligent control platform network, and the intelligent control platform is connected to the intelligent control valve and the drainage ditch system through the control box The sensors interact with each other; the AI ​​camera, real-time traffic situation data access software and the intelligent control platform network are connected; the intelligent control platform obtains the gutter images collected by the AI ​​camera, the PH value data collected by the sensor and the traffic conditions of the real-time traffic situation data access software, and analyzes whether the water currently flowing into the gutter is sewage or initial rain according to the gutter images, PH value data and traffic conditions. If the water in the gutter is sewage or initial rain and the intelligent control valve is open, the control box is sent to close the intelligent control valve. The command is sent to the control box to control the intelligent control valve to close, so that the water in the gutter is discharged from the sewage outlet into the ecological ditch to complete the purification treatment. In this way, the environmental protection requirements for the discharge of initial rain and sewage on the bridge deck can be met, and the landscape visual effect is good. It further realizes the intelligent management of the drainage system, improves the management efficiency and accuracy, timeliness and safety, realizes automated management, and reduces the management operation and maintenance costs.

[0044] In one embodiment, the intelligent drainage system based on ecological ditch water treatment also includes an emergency button; the emergency button is installed in an easily accessible location near the drainage ditch system, and the emergency button is connected to the control box network. The emergency button is used to trigger the emergency processing mechanism when the intelligent control platform cannot control the intelligent control valve through the control box.

[0045] Among them, the emergency button is set in an easily accessible position, such as on the guardrail. Once the drainage ditch system fails or abnormalities, the staff can press the button in time to trigger the emergency handling mechanism.

[0046] Among them, the emergency button can also be used to control the intelligent control valve during the later maintenance, daily inspection and anti-lock braking of the drainage ditch system.

[0047] In one embodiment, analyzing whether the water currently flowing into the gutter is sewage or initial rain according to the gutter image, pH value data and traffic conditions includes:

[0048] Obtain weather conditions to determine whether it is raining currently. If it is raining, obtain the time for rainwater to flow into the drain ditch after rain. When the time for rainwater to flow into the drain ditch after rain is less than the preset time, determine that the water in the drain ditch is initial rain; when the time for rainwater to flow into the drain ditch after rain is greater than the preset time, determine that the water in the drain ditch is rainwater after initial rain; determine whether the pH value of the water in the drain ditch is within the preset pH value range through pH value data; use image recognition technology to identify the drain ditch image to determine whether the water in the drain ditch image contains oil or debris; analyze the moving speed of the vehicle from the traffic situation to determine whether the vehicle stationary time exceeds the preset threshold; determine that the water in the drain ditch is sewage when the pH value of the water is not within the preset pH value range, the water in the drain ditch image contains oil or debris, or the vehicle stationary time exceeds the preset threshold.

[0049] Among them, the preset time can be set according to actual conditions such as water flow speed or size, such as: 10 minutes, 15 minutes, etc.

[0050] Among them, the preset pH value range can be set according to the acidity and alkalinity judgment standard of water that is not sewage, such as 6.5-8.5.

[0051] Among them, the preset threshold can be set according to the stay time in situations such as vehicle congestion, vehicle breakdown or traffic accident, such as: 10 seconds, 15 seconds, etc.

[0052] It should be understood that in situations such as traffic congestion, vehicle breakdown or car accidents, there may be gasoline leaks, etc. If gasoline leaks, it may flow into the gutter, polluting the water in the gutter and becoming sewage. Therefore, it cannot be discharged directly into the river and needs to be purified. Therefore, when the vehicle stationary time exceeds the preset threshold, there may be traffic congestion, vehicle breakdown or car accidents, and the water in the gutter can be considered sewage.

[0053] In one embodiment, the ecological ditch includes a first ecological filter dam, a surface flow wetland, an ecological pond wetland, and a second ecological filter dam;

[0054] The first ecological filter dam is located upstream of the surface flow wetland, the surface flow wetland is located upstream of the ecological pond wetland, and the ecological pond wetland is located upstream of the second ecological filter dam; among them, the first ecological filter dam is composed of gravel, emergent plants and ceramic granular soil of different specifications; the surface flow wetland is composed of gravel, floating plants, fish, shellfish and biological flora; the ecological pond wetland is composed of submerged plants, fish, shellfish and biological flora; the second ecological filter dam is composed of gravel, emergent plants and ceramic granular soil of different specifications.

[0055] Among them, ecological ditches improve water quality, improve the ecological environment, and create a good landscape effect through natural organisms, plant filtration and microbial flora, without any adverse impact on the local ecological environment.

[0056] Among them, the ecological ditch is used as a purification area for sewage and initial rain. The water purification process of the ecological ditch is as follows: Figure 4 As shown, sewage and initial rain flow into the ecological ditch, first pass through the first ecological filter dam to filter out sediment and oil, then flow into the surface wetland to purify the water quality through plants and biological flora, and then pass through the plants and biological flora in the ecological pool wetland to purify the water quality again, and finally pass through the second ecological filter dam to filter again, so that the sewage or initial rain is purified to meet the standards and discharged.

[0057] In one embodiment, the intelligent drainage system based on ecological ditch water treatment also includes: when the water in the drainage ditch is sewage or initial rain, but the intelligent control valve is closed, the water quality of the water in the drainage ditch is continuously monitored, and when it is monitored that the water in the drainage ditch is not initial rain, the pH value of the water is not within the preset pH range, there is no oil or debris, the sewage generated by the last traffic accident has been treated and no traffic accidents have occurred recently, a command to open the intelligent control valve is sent to the control box, so that the control box controls the intelligent control valve to open, thereby allowing the water in the drainage ditch to be discharged from the direct discharge outlet.

[0058] In one embodiment, the intelligent drainage system based on ecological ditch water treatment further includes: when the water in the drainage ditch is not sewage or initial rain and the intelligent control valve is open, continuously monitoring the water quality of the water in the drainage ditch.

[0059] The above-mentioned intelligent drainage system based on ecological ditch water treatment solves the problems of low efficiency of traditional bridge drainage, non-energy-saving materials, poor timeliness, lack of continuity and sustainability, secondary pollution risk to the environment, landscape, high cost and poor effect of secondary treatment of rainwater and sewage, lack of friendly cooperation with local ecology, high maintenance cost, and lack of complete system database data. In order to achieve the coordinated work of drainage and water treatment, an efficient and environmentally friendly drainage and water treatment solution is provided to make drainage safe, environmentally friendly, timely and controllable, providing a case reference for the intelligent and ecological drainage system in urban development.

[0060] The software and hardware equipment involved in the whole process of the intelligent drainage system based on ecological ditch water treatment are 100% prefabricated, and more than 85% of the construction and installation are assembled. The process is simple, the construction is controllable, and the overall economic cost is low. It not only improves drainage efficiency and reduces energy consumption, but also improves water quality and landscape effects through ecological treatment measures, realizing the intelligence and ecology of the drainage system.

[0061] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
