Urban road ponding monitoring device and method

Abstract

The invention discloses an urban road ponding monitoring device and method in the field of urban roads. The monitoring device includes a thunder-vision all-in-one machine, and the thunder-vision all-in-one machine is connected with an external power supply module through a power supply interface. The power supply module provides a 24V direct-current power supply; and a millimeter wave radar module, a video module and a control module are arranged in the thunder-vision all-in-one machine. The control module is driven by a CAN bus for communication with the millimeter wave radar module for synchronously superposing ponding depth data and ponding state information on the video module; wherein the video module is connected with the control module through an image interface and outputs a real-time video of a road water accumulation point, and the thunder-vision all-in-one machine communicates with a network transmission module through an Ethernet interface to realize information interactionwith a remote monitoring center background and display a water accumulation site video and water accumulation depth data in real time; in other detection modes, a detection sensor and a monitoring video are respectively opposite, the system is complex and low in fault tolerance, the road ponding depth is monitored in a non-contact mode, and the defect that the mounting positions of other sensorsare limited is overcome.

Description

technical field [0001] The invention relates to the technical field of urban roads, in particular to an urban road water accumulation monitoring device and method. Background technique [0002] Heavy rainfall often causes a large amount of water accumulation in low-lying urban roads such as concave overpasses and tunnels, which brings great inconvenience and safety hazards to residents' normal travel, and even causes property damage and casualties. [0003] The existing urban road water monitoring methods mainly use ultrasonic water level gauges, electronic rulers, or buried liquid level detectors as sensor detection devices. Monitoring cameras are installed on site, and water level warning information is displayed on the LED display screen. At the same time, optical fiber or GPRS wireless The network transmits the water level information to the server workstation of the monitoring center for processing, analysis and display, such as figure 2 shown. [0004] The traditiona...

Problems solved by technology

[0006] (2) The road water detection sensor and video surveillance are independent of each other and have no linkage

[0007] (3) Road water accumulation detection sensors mainly use equipment such as ultrasonic water level gauges, electronic rulers or liquid level gauges. When installing such sensors, it is necessary to reserve water accumulation points and sensor locations. There are blind spots in detection, and the installation location is limited.
