Urban tunnel ponding monitoring system and monitoring method based on UHF RFID passive tag

Abstract

The invention discloses an urban tunnel ponding monitoring system and monitoring method based on UHF RFID passive tags. The system comprises a background master station and an ponding monitoring device, wherein the background master station and the ponding monitoring device are in communication connection through a 5G public communication network; the ponding monitoring device comprises a passive water depth monitoring scale, a reader-writer, a controller, a warning handrail and a camera; a plurality of UHF RFID passive tags are arranged on the passive water depth monitoring scale in an array mode and pasted to the side wall of the middle section of an urban tunnel; the reader-writer is fixedly arranged at the top of the middle section of the urban tunnel close to the passive water depth monitoring scale; when the urban tunnel ponding monitoring system works, the reader-writer communicates with the UHF RFID passive tag through RF space electromagnetic field coupling, when ponding exists in an urban tunnel, the UHF RFID passive tag arranged on the passive water depth monitoring scale at a lower position is submerged by the ponding, at the moment, normal communication cannot be performed between the reader-writer and the UHF RFID passive tag submerged by the ponding, therefore, ponding in the tunnel can be judged, the ponding depth is calculated, and an alarm is given.

Description

technical field [0001] The invention relates to the technical field of urban traffic early warning, in particular to an urban tunnel waterlogging monitoring system and monitoring method based on UHF RFID passive tags. Background technique [0002] With the rapid development of the domestic economy, the number of domestic cars has increased rapidly, so the phenomenon of urban traffic congestion is becoming more and more prominent; in order to alleviate the phenomenon of urban traffic congestion, there are more and more traffic overpasses and urban tunnels in the city; but it is rainy in summer In seasons, urban tunnels often have water accumulation problems. When the height of the water accumulation exceeds a certain depth and motor vehicle drivers do not know the depth of the water accumulation in the tunnel, it is very easy for vehicles to stall and people to drown when they risk driving through the tunnel through the water. Casualties have brought huge losses to people's l...
