Description

Technical Field

[0001] This invention relates to the field of municipal engineering technology, and in particular to a visual intelligence-based device for detecting structural defects in municipal manhole covers. Background Technology

[0002] In the investigation of safety hazards in municipal engineering projects, manhole covers, as a core component of urban infrastructure, are directly related to the safety of urban road operations due to their structural integrity. Because manhole covers are prone to various structural defects during long-term service, specialized inspections are conducted using manhole cover defect detection devices based on visual intelligence technology. These devices accurately determine the presence of structural defects through visual recognition, thereby selecting defect-free and safety-compliant manhole covers for use and ensuring the safety of urban road traffic.

[0003] According to CN202420460052.6, this utility model discloses a manhole cover damage detection device, relating to the field of urban infrastructure management technology. It solves the shortcomings of existing manhole cover detection methods, which cannot specifically determine the degree of damage or the exact location of the damage. This utility model includes a manhole cover damage detection circuit, a microcontroller, an LCD display module, and a LoRa wireless communication module. This utility model can determine the damage level of the manhole cover by judging the breakage of the wire between the parallel resistor and the grounding terminal from the finally collected voltage data. Several detection circuits are each connected to an input port of the microcontroller. By analyzing the data received from different ports, it can determine which port's data is abnormal, and then determine the location of the manhole cover damage. Furthermore, this utility model also displays the damage level in real time on the LCD screen and further transmits the damage data to a terminal, facilitating remote global control of whether the manhole cover needs repair based on the data.

[0004] However, when inspecting the inner wall of manhole covers, existing manhole cover defect detection devices generally use handheld detection devices. Operators need to open the manhole cover first, and then use the device to scan the inner wall of the manhole cover area by area. This type of detection method is not only cumbersome, but also very easy to cause some areas to be incompletely covered due to human error, which will have an adverse effect on the overall quality and accuracy of manhole cover defect detection.
