Description

Technical Field

[0001] The present invention belongs to the technical field of road supporting engineering, and in particular relates to an intelligent recognition, early warning and processing system for icing on a bridge pavement. Background Art

[0002] Meteorological disasters are a major cause of traffic accidents, especially in winter, when freezing roads can easily lead to major accidents. Unlike solid foundations on ground roads, bridges are mostly suspended overhead structures. Without the ground's heat, the heat quickly dissipates once temperatures drop, causing ice to form. Therefore, in cold or snowy weather, ordinary roads, due to their higher surface temperatures, remain frozen, while bridge pavement, at its lower surface temperature, freezes, posing a serious threat to traffic safety.

[0003] Currently, when dealing with bridge icing, the identification, prevention, and treatment of bridge icing is generally done through manual inspections, spraying deicing agents with engineering vehicles, or mechanical deicing. However, this has the following shortcomings:

[0004] (1) Due to the heavy traffic on bridge sections, manual inspections in low-temperature and severe weather conditions inherently pose certain safety risks. In addition, manual inspections are also inefficient and cannot predict when bridges will freeze, which will delay the timing of preventing bridge ice. At the same time, manual inspections are difficult to achieve real-time monitoring and timely warnings when responding to sudden severe weather. (2) Using engineering vehicles to spray de-icing agents or mechanical de-icing is not only inefficient, but also causes obstructions to the passage of vehicles on busy bridge sections. In addition, it is also impossible to respond to sudden ice and snow or sudden drops in temperature in a timely manner. (3) When preventing and dealing with bridge ice, it usually requires the coordination and cooperation of multiple management departments such as transportation and road administration. When coordination is not smooth and there is information gap in communication, it is easy to delay the prevention and treatment of ice. Summary of the Invention

[0005] The technical problem solved by the present invention is to provide an intelligent recognition, early warning and processing system for bridge pavement icing, which can intelligently identify and analyze the icing conditions of the bridge, automatically spray ice-melting agents to prevent the bridge pavement from icing or melt the ice on the icy pavement, and at the same time intelligently dispatch and control the passage of vehicles on the bridge and provide early warning guidance.

[0013] The icing prevention and traffic control module includes: receiving predicted weather information; when the predicted weather information shows ice and snow weather or the temperature drops sharply below zero, an icing warning message is sent to the administrator terminal for reminder; comparing the real-time temperature and humidity data with the temperature and humidity warning value; if the real-time temperature and humidity data reaches the temperature and humidity warning value, an icing prevention instruction is sent to the icing prevention and information collection device to spray the ice melting agent to the bridge surface through the atomizing nozzle, and using the bridge surface camera and the infrared icing sensor to respectively collect the image information and ice thickness information of each bridge surface section, and at the same time send a restriction instruction to the vehicle traffic diversion device to pass through the traffic signal The traffic light limits the number of vehicles entering the bridge; it is used to receive bridge deck icing information and compare it with the set threshold of severely iced bridge deck sections. When the number of severely iced bridge deck sections is greater than or equal to the set threshold, a no-entry instruction is issued to the vehicle traffic diversion device, so as to prompt vehicles not to enter the bridge through traffic lights and block the bridge entrance with a vehicle blocking device. When the number of severely iced bridge deck sections is less than the set threshold, a slow-down instruction is issued to the vehicle traffic diversion device and the icing prevention and information collection device, so as to limit the number of vehicles entering the bridge through traffic lights and use the icing warning lights of each bridge deck section to display different colors of lights corresponding to the icing level for warning and guidance.

[0024] Compared with the prior art, the present invention has at least the following beneficial effects:

[0025] 1) The system of the present invention uses meteorological observation stations to obtain forecast weather information, thereby providing early warnings to management personnel, allowing them ample time to inspect and maintain the system. Furthermore, the system uses temperature and humidity sensors to monitor the real-time temperature and humidity data of the bridge deck. When the real-time temperature and humidity data reaches the temperature and humidity warning value, the system can automatically and efficiently spray de-icing agent to each bridge deck section to prevent ice from forming on the bridge surface. At the same time, it automatically controls traffic lights to restrict vehicle entry to prevent excessive vehicles from affecting the de-icing agent spraying.

[0026] 2) The present invention divides the bridge into several sections and installs bridge deck cameras and infrared ice sensors in each section to collect image information and ice thickness information for each section. The ice information processing module then analyzes and calculates the severity of ice on each section. This information is then used to control the ice warning lights on each section, as well as the traffic lights and vehicle barriers at the bridge entrances, to intelligently dispatch and manage traffic on the bridge, providing early warning and guidance. This ensures the orderly and safe passage of vehicles under varying degrees of ice severity. Furthermore, the system can intelligently screen and count severely iced sections, as well as the frequency of occurrence of different ice levels on each section. This allows targeted re-spraying of ice-melting agents on severely iced sections to improve the icing condition of the bridge deck, and to inspect and repair bridge deck quality defects on sections with a high frequency of severe ice.

[0027] 3) The system of the present invention is highly intelligent, and requires little human intervention in the process of identifying, warning, and handling bridge icing. This effectively solves the problem that traditional handling of bridge icing requires the coordinated cooperation of personnel from multiple departments, which is prone to poor coordination and information gaps, leading to delays in preventing and handling bridge deck icing.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0037] The present invention will be further described in detail below with reference to the accompanying drawings.

[0038] Example 1

[0039] Bridge and pavement icing intelligent identification, warning and processing system, please refer to Figures 1 to 6 , which includes: a meteorological observation station 1, a temperature and humidity sensor, an icing prevention and information collection device 4, an icing information processing module, an icing prevention and traffic control module, a vehicle traffic diversion device 5 and an administrator terminal;

[0040] See also Figure 1 The left and right bridge decks of the bridge 3, i.e., the two-way bridge decks, are continuously and evenly divided into a plurality of bridge sections 301; the length of the bridge sections 301 is 50 to 120 meters, and the bridge sections 301 on the left and right bridge decks are symmetrically arranged with the dividing strip 2 as the axis;

[0041] The meteorological observation station 1 is set up near the bridge to monitor the meteorological data of the bridge in real time and send it to the icing information processing module; the meteorological data includes temperature, humidity, air pressure, wind speed and wind direction; when the conditions for station establishment are not available, the meteorological observation station 1 can use the nearest local meteorological observation station as a station;

[0042] The temperature and humidity sensors are pre-buried in the bridge deck to monitor the real-time temperature and humidity data of the bridge deck and send them to the icing prevention and traffic control module. Preferably, multiple temperature and humidity sensors can be deployed according to the length of the bridge, and they are evenly distributed on the bridge deck along the bridge direction. The real-time temperature and humidity data collected by the temperature and humidity sensors can be converted by a Modbus / TCP protocol converter and sent to the icing prevention and traffic control module via remote TCP of the converter.

[0043] See also Figures 2 to 5The icing prevention and information collection device 4 includes an ice-melting agent storage tank 401 located near the bridge, an ice-melting agent delivery pipe 402 located along the bridge on the median strip 2, an atomizing nozzle 403, a delivery pump 408 for pumping the ice-melting agent in the ice-melting agent storage tank 401 to the atomizing nozzle 403 through the ice-melting agent delivery pipe 402, a working bracket 404 located on the median strip 2, and an ice warning light 404 located on each bridge deck section 701 and mounted at the end of the working bracket 404. 07, bridge deck camera 405 and infrared ice sensor 406; the atomizing nozzle 403 is evenly arranged on both sides of the dividing strip 2 along the bridge direction, so as to spray ice melting agent to each bridge deck section on both sides of the dividing strip 2; the bridge deck camera 405 is used to capture and obtain image information of the corresponding bridge deck section and send it to the ice information processing module; the infrared ice sensor 406 is used to monitor and obtain ice thickness information of the corresponding bridge deck section and send it to the ice information processing module; wherein, the atomizing nozzle 403 is arranged on each bridge deck section. The number of beam sections should be sufficient to ensure that the de-icing agent sprayed by them can cover the corresponding bridge sections. The atomizing nozzle 403 adopts a nozzle with freely adjustable angle to increase the spray coverage range of a single nozzle, thereby reducing the number of nozzles used. The atomizing nozzle 403 is provided with an electromagnetic valve. The system controls the opening / closing and rotation angle of the atomizing nozzle on each bridge deck section by issuing instructions. The bridge deck camera 405 is a 3-5 million pixel high-definition camera used for road monitoring. Multiple cameras can be set up on each bridge section to ensure that the road surface of the corresponding bridge section can be covered. When the infrared ice sensor is working, due to the different absorption coefficients of infrared light in ice and water, and the infrared reflection coefficients of ice surfaces of different thicknesses are also different, the infrared ice sensor transmits and receives infrared light to the bridge deck, analyzes the absorption coefficients of infrared light of different wavelengths to determine whether the medium it passes through is ice or water, and then illuminates the ice surface with infrared light of the same wavelength. The ice thickness information can be obtained through the infrared reflection coefficient of the ice surface.

[0044] See also Figure 2 The vehicle traffic diversion device 5 includes a traffic light 501 installed at all fork intersections entering the bridge and a vehicle blocking device 502 at the entrance; wherein, when there is an existing traffic light 501 at the fork intersection entering the bridge, the system of the present invention can be connected to the traffic light 501; the vehicle blocking device 502 can move according to the system instruction to make the entrance blocked or open; the vehicle blocking device 502 can adopt the existing technology of buried lifting blocking pile, and the top of the buried lifting blocking pile is equipped with a warning light, and the side of the lifting pile is coated with a reflective warning strip, or the existing technology of the lifting blocking pole is adopted, and the blocking pole is also equipped with a warning light and a reflective warning strip;

[0045] See also Figure 6The icing information processing module includes: a module for analyzing and calculating the forecast weather information of the bridge location for a period of time in the future based on the meteorological data, and sending the forecast weather information to the icing prevention and traffic control module; a module for analyzing and calculating the ice area of ​​each bridge deck segment based on the image information of each bridge deck segment through image recognition technology, and classifying and counting the ice severity of each bridge deck segment according to different icing levels of uniced, slightly iced and severely iced, in combination with the ice thickness information of each bridge deck segment, so as to obtain bridge deck icing information and send the forecast weather information to the icing prevention and traffic control module and the administrator terminal; generally, the forecast weather information should include weather information for more than 5 days in the future;

[0046] See also Figure 6 The icing prevention and traffic control module includes:

[0047] It is used to receive forecast weather information. When the forecast weather information shows ice and snow weather or the temperature drops sharply below zero degrees, an ice warning message is sent to the administrator terminal for reminder, so that the administrator can maintain and inspect the system equipment such as the ice prevention and information collection device, the vehicle traffic diversion device and the temperature and humidity sensor in advance according to the prompt information to ensure the normal operation of the system in the future. Specifically, when maintaining and inspecting the ice prevention and information collection device, the following steps are usually followed: check whether there is a sufficient amount of ice melting agent stored in the ice melting agent storage tank 401; check whether the ice warning light 407, the bridge deck camera 405 and the infrared ice sensor are working properly; start the delivery pump, and observe through the bridge deck camera whether the atomizing nozzle can spray the ice melting agent normally, and whether the sprayed ice melting agent can normally cover the corresponding bridge deck section;

[0048] It is used to compare the real-time temperature and humidity data with the temperature and humidity warning value. If the real-time temperature and humidity data reaches the temperature and humidity warning value, an anti-icing instruction is issued to the ice prevention and information collection device 4 to spray an ice-melting agent onto the bridge deck through the atomizing nozzle 403, and use the bridge deck camera 405 and the infrared ice sensor 406 to respectively collect image information and ice thickness information of each bridge deck section. At the same time, a traffic restriction instruction is issued to the vehicle traffic diversion device 5 to limit the number of vehicles entering the bridge through the traffic light 501, thereby preventing too many vehicles from entering the bridge deck and affecting the spraying effect of the ice-melting agent. The temperature and humidity warning value is higher than the historical average value of the temperature and humidity of the bridge deck when ice occurs. Generally, the temperature in the temperature and humidity warning value is 2 to 3 degrees Celsius higher than the historical average temperature of the temperature and humidity of the bridge deck when ice occurs, and the relative humidity in the temperature and humidity warning value is 80% to 90% of the historical average relative humidity of the temperature and humidity of the bridge deck when ice occurs.

[0049] It is used to receive bridge deck icing information and compare it with the set threshold of severely iced bridge deck sections. When the number of severely iced bridge deck sections is greater than or equal to the set threshold, a no-entry instruction is issued to the vehicle traffic diversion device 5, so as to prompt vehicles not to enter the bridge through the traffic light 501 and block the bridge entrance using the vehicle blocking device 502. When the number of severely iced bridge deck sections is less than the set threshold, a slow-down instruction is issued to the vehicle traffic diversion device 5 and the icing prevention and information collection device 4, so as to limit the number of vehicles entering the bridge through the traffic light 501 and display different colors of lights corresponding to the icing level through the icing warning lights 407 of each bridge deck section to warn and guide vehicles, so that the driving speed can be controlled in an orderly manner to ensure traffic efficiency and safety. Generally, the threshold of severely iced bridge deck sections is 20%-30% of the total number of bridge sections of the bridge, that is, when the severely iced road section is greater than 20%-30% of the total length of the bridge, the bridge should be temporarily closed for management.

[0050] Further, in a preferred embodiment, see Figure 3 The icing prevention and information collection device 4 also includes a booster pump 409 provided on the de-icing agent delivery pipe 402 and corresponding to each bridge deck section 701. In the case of a long bridge, the pressure of the de-icing agent will decrease when it is delivered to a distant bridge deck section by the delivery pump 408. By providing the booster pump 409, the pressure of the atomizing nozzles on each bridge deck section can be ensured to be balanced.

[0051] Further, in a preferred embodiment, see Figure 3 and Figure 4 The icing prevention and information collection device 4 also includes a lighting lamp 4010, which is installed at the end of the working bracket 404; the lighting lamp 4010 can illuminate the bridge deck at night, so that the bridge deck camera 405 can capture clearer images. At the same time, the lighting lamp 4010 can also be used as a street light for bridge driving when necessary.

[0052] Further, in a preferred embodiment, see Figure 2 and Figure 3The icing prevention and information collection device 4 further includes a water pipe 4011, one end of which is connected to the end of the de-icing agent delivery pipe 402 near the de-icing agent storage tank 401, and the other end is connected to the tap water network. Solenoid valves 4012 are provided on both sides of the connection between the water pipe 4011, the de-icing agent delivery pipe 402 and the water pipe 4011. Based on the above arrangement, in spring or summer when the temperature is high and the bridge deck does not freeze, the solenoid valves 4012 at different positions can be reasonably controlled to directly input clean water into the de-icing agent delivery pipe 402 through the tap water network using the water pipe 4011, and finally sprayed out through the atomizing nozzle 403 to achieve daily cleaning of the bridge deck. In addition, when it is necessary to pump clean water into the de-icing agent storage tank 401 to prepare liquid de-icing agent, the clean water can also be directly transported to the de-icing agent storage tank 401 through the water pipe 4011.

[0053] Furthermore, in a preferred embodiment, the administrator terminal includes a mobile phone, a notebook and a tablet computer.

[0054] Furthermore, in a preferred embodiment, the icing warning light 407 can display green, yellow or red light to correspond to the uniced, slightly iced and severely iced levels of the bridge deck section, respectively.

[0055] Furthermore, in a preferred embodiment, the icing prevention and traffic control module also includes a module for receiving bridge deck icing information, screening out lightly iced and severely iced bridge deck sections, and analyzing and calculating the amount of ice-melting agent required for melting ice on each bridge deck section based on the ice thickness and ice area of ​​each screened bridge deck section, and issuing an ice-removing instruction to the icing prevention and information collection device 4, so as to spray the required amount of ice-melting agent to the corresponding bridge deck section through the atomizing nozzle 403; when the system issues an ice-prevention instruction to spray the ice-melting agent to each bridge deck section, When spraying de-icing agents, due to the different road conditions of each bridge deck section, for example, there is low-lying water accumulation on a certain section of the bridge deck, the bridge deck is relatively wet, or the spraying of de-icing agents is affected by the passing vehicles, some bridge deck sections may still be difficult to prevent from icing after spraying de-icing agents. At this time, the system will issue a de-icing command to spray the appropriate amount of de-icing agents again on the slightly iced and severely iced bridge deck sections to improve the icing conditions of the bridge deck. At the same time, it can also avoid the problem of de-icing failure caused by insufficient spraying of de-icing agents, or waste caused by excessive use of de-icing agents.

[0056] Furthermore, in a preferred embodiment, the system of the present invention also includes a data storage module, which is used to store meteorological data of the bridge location, real-time temperature and humidity data of the bridge deck, predicted weather information, image information and ice thickness information of each bridge deck section, and bridge deck icing information.

[0057] Generally, frequent severe icing on the bridge deck may cause quality defects in the bridge deck. At the same time, if the bridge deck has quality defects such as unevenness, cracks or voids, it is easy for water to accumulate on the bridge surface and it is more prone to icing. Therefore, based on the above connection, some bridge deck sections are prone to severe icing even if ice-melting agents are sprayed in low temperature or snowy weather. Furthermore, in a preferred embodiment, the icing information processing module also includes a function for analyzing and counting the frequency of occurrence of different icing levels of each bridge deck section based on the historical data of bridge deck icing information stored in the data storage module, so as to screen out all bridge deck section information with a higher frequency of severe icing and send it to the administrator terminal; based on the above functions, the administrator can conduct targeted inspections and repairs on bridge deck quality defects of bridge deck sections with a higher frequency of severe icing.

[0058] When the bridge is severely iced and needs to be closed, all entrances to the bridge should be blocked. In order to ensure that the vehicle can be stopped more safely by the vehicle stopping device 502, further, in a preferred embodiment, please refer to Figure 2 The vehicle traffic diversion device 5 also includes a speed bump 503 located on the bridge deck in the direction of the vehicle stopping device 502.

[0059] Furthermore, in a preferred embodiment, the working bracket 404 is in an inverted V-shape, with its bottom fixed on the dividing strip 2 and the top end extending above the bridge deck on both sides of the dividing strip 2; preferably, the height of the working bracket 404 can be adjusted up and down, and the spacing between the top ends of the working bracket 404 can be freely adjusted, so that the working bracket 404 can be suitable for bridge decks with different numbers of lanes.
