Description

Technical Field

[0001] This application relates to the technical field of road detection, and particularly to a monitoring device for water accumulation in underpass roads based on radar sensing. Background Art

[0002] Underpass roads can relieve ground traffic pressure, reduce intersection congestion, and improve traffic efficiency. However, due to their low terrain, underpass roads are more likely to accumulate a large amount of water during rainy or snowy weather, especially during heavy rain, posing a potential hazard to driving safety. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, one of the purposes of this application is to provide a monitoring device for water accumulation in underpass roads based on radar sensing, which has the advantages of being able to timely warn of water accumulation, prompt vehicles, and reduce potential hazards to driving safety.

[0004] The above object of this application is achieved through the following technical solutions:

[0005] A monitoring device for water accumulation in underpass roads based on radar sensing includes a collection component, a power supply component, and a control system. The collection component is used to collect the water accumulation situation of the underpass road. The power supply component is used to supply power to the collection component. The control system includes a weather module, a judgment module, and a prompt module. The weather module obtains weather information. If it is rainy or snowy weather, it controls the collection component to collect data. The judgment module obtains the data collected by the collection component and makes a judgment. When the water accumulation reaches the lowest water level, a warning is issued.

[0006] By adopting the above technical solutions, during use, when it is detected that there is rainy or snowy weather, the collection component is controlled to collect data, and the collected data is judged. When the water accumulation reaches the lowest water level, a warning is issued, thereby being able to reduce potential hazards to driving safety.

[0007] In a preferred example of this application, it can be further configured as follows: The weather module obtains weather information. If it is rainy or snowy weather, it obtains the precipitation and sends the precipitation to the judgment module. The judgment module combines the precipitation and the drainage volume to judge the water accumulation volume, calculates the time Tc required for the water accumulation to reach the lowest water level, and compares Tc with the time Ts when the water accumulation data collected by the collection component reaches the lowest water level. If Tc is greater than Ts, the judgment module obtains the change in precipitation during the Ts time period. If the precipitation shows an increasing trend, no prompt is made. If the precipitation does not show an increasing trend, a drainage failure prompt is made.

[0008] By adopting the above technical solution, that is, by calculating the precipitation and drainage volume, the time required to reach the lowest water level line is obtained, and it is compared with the time obtained through actual measurement, and combined with the precipitation change trend during this period, so as to judge whether there is a drainage fault.

[0009] In a preferred example of the present application, it can be further configured that: after giving a drainage fault prompt, the judgment module obtains the water flow of the drainage pipeline in the nearby area and makes a judgment. If the water flow does not reach the high load value, a drainage blockage prompt is given.

[0010] By adopting the above technical solution, after it is judged that there is a drainage fault, the water flow of the drainage pipeline in the nearby area (that is, the drainage pipeline connected to the drainage outlet of the detection area) is detected. If the water flow does not reach the high load value (that is, the drainage pipeline still has load capacity), it indicates that there is a phenomenon of drainage outlet blockage.

[0011] In a preferred example of the present application, it can be further configured that: if Tc is less than Ts, the judgment module obtains the change of precipitation during the Ts time period. If the precipitation shows a decreasing trend, no prompt is given. If the precipitation does not show a decreasing trend, a collection fault prompt is given.

[0012] By adopting the above technical solution, when the actual time taken to reach the lowest water level is greater than the calculated time, the precipitation is judged. If the precipitation does not show a decreasing trend, it indicates that there is a fault in the collection component.

[0013] In a preferred example of the present application, it can be further configured that: the weather module obtains weather information. If it is rainy or snowy weather, the type of rainy or snowy weather is obtained. If it is short-term heavy rainfall, a water accumulation prompt A for the underpass road is given at a certain distance before the underpass road.

[0014] By adopting the above technical solution, when it is short-term heavy rainfall, a water accumulation prompt A for the underpass road is given at a certain distance before the underpass road, so as to be able to give a prompt to the driver in advance.

[0015] In a preferred example of the present application, it can be further configured that: if it is continuous rainfall, when the water accumulation reaches the lowest water level, a water accumulation prompt B for the underpass road is given at a certain distance before the underpass road.

[0016] By adopting the above technical solution, when it is continuous rainfall, when the water accumulation reaches the lowest water level, a water accumulation prompt B for the underpass road is given at a certain distance before the underpass road, so as to be able to give a prompt to the driver in advance when the water accumulation reaches the lowest water level line.

[0017] In a preferred example, the present application can be further configured as follows: the water accumulation information B includes the current water level and the water level after X time; X time is the time to reach the water accumulation location from the prompt location under the current road speed limit conditions, wherein the water level after X time is calculated by the judgment module through judgment and measurement based on precipitation, drainage and X time.

[0018] By adopting the above technical solution, the possible water level can be predicted and displayed in advance, which helps the driver to make judgments and choose a reasonable road. DETAILED DESCRIPTION

[0019] The present application discloses a radar-based underpass road water accumulation monitoring device, including a collection component, a power supply component and a control system. The collection module is used to collect water accumulation on the underpass road, and the functional component is used to supply power to the collection component. The control system includes a weather module, a judgment module and a prompt module. The weather module obtains weather information, and if it is rainy or snowy, it controls the collection component to collect data. The judgment module obtains the data collected by the collection component and makes a judgment. When the water reaches the lowest water level, an alarm is issued. In this embodiment, the collection component can be a laser radar, an ultrasonic radar, an infrared radar, etc.

[0020] If the weather information obtained by the weather module is rainy or snowy, the precipitation is obtained and sent to the judgment module. The judgment module judges the amount of water accumulation based on the precipitation and drainage, and calculates the time Tc required for the water accumulation to reach the lowest water level. Tc is compared with the time Ts when the water accumulation data collected by the acquisition component reaches the lowest water level. If Tc is greater than Ts, the judgment module obtains the change in precipitation within the Ts time period. If the precipitation is increasing, no prompt is given. If the precipitation is not increasing, a drainage fault prompt is given. After the drainage fault prompt is given, the judgment module obtains the water flow of the drainage pipeline in the nearby area and makes a judgment. If the water flow does not reach the high load value, a drainage blockage prompt is given. When the drainage is blocked, the future precipitation is judged, and it is predicted whether the water flow of the drainage pipeline in the nearby area will run at full load. If it will run at full load, the blocked area will not be dredged. If it will not run at full load, the drainage volume is calculated based on the precipitation and the speed of the accumulation of water. If the drainage volume is less than the set value, a dredging prompt is given.

[0021] If Tc is less than Ts, the judgment module obtains the change of precipitation in the Ts time period. If the precipitation shows a decreasing trend, no prompt is given. If the precipitation does not show a decreasing trend, a collection failure prompt is given.

[0022] When the weather information obtained by the weather module is rainy or snowy weather, obtain the type of rainy or snowy weather. If it is heavy rainfall in a short period of time, give water accumulation prompt A for the underpass road within a certain distance before the underpass road. Water accumulation prompt A includes the current water level of the underpass road and the duration of the current rainfall.

[0023] If it is continuous rainfall, when the water accumulation reaches the lowest water level, give water accumulation prompt B for the underpass road within a certain distance before the underpass road. Water accumulation information B includes the current water level and the water level after X hours; X hours is the time from the prompt position to the water accumulation position under the current road speed limit condition. The water level after X hours is obtained by the judgment module through judgment and calculation based on the precipitation, drainage volume, and X hours. Water accumulation prompt A and water accumulation prompt B can be displayed through a display screen, voice broadcast, access to navigation, etc.

[0024] The implementation principle of this embodiment is as follows: By obtaining weather information, obtaining precipitation, and detecting the water accumulation depth, the detection effect of water accumulation can be better, so that a good prompt effect can be achieved for drivers. At the same time, by detecting the drainage speed and the load of the drainage pipeline, drainage data can be obtained, which is convenient for adjusting the drainage.

[0025] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
