Abstract
The invention discloses an anti-lightning tunnel waterlogging warning system and method based on a 4G network, and belongs to the field of warning systems. An existing tunnel water level monitoring system cannot achieve sharing of monitoring data, only conducts partial adjustments when waterlogging problems occur, and thus is not conducive to traffic condition unified supervision and traffic flow control. The anti-lightning tunnel waterlogging warning system based on the 4G network comprises an information processing transmission unit (1), a water level detection unit (2), a warning unit (3), a command unit (4), a lightning protection unit (5) and a power supply unit (6). According to the anti-lightning tunnel waterlogging warning method based on the 4G network, in an on-duty state, the water level detection cycle is t1, and at the time of detection, a detection module (16) is used for powering the other parts to conduct water level detection; if the water level information is not detected, the power is cut off, and after waiting for t1, repeated actions is conducted; if the water level information is detected, the working state is started, water level depth information is detected and uploaded at a interval of t2. Detection and uploading frequencies are fast, and the anti-lightning tunnel waterlogging warning system can be used for detecting and warning waterlogging in the extreme rainstorm weather.
