Embodiment 1
[0041] Such as Figure 1-3 As shown, Embodiment 1 of the present disclosure provides a non-contact railway tunnel lining defect monitoring and early warning system, including monitoring equipment 1 arranged at the spandrel in the railway tunnel, and the monitoring equipment includes ultrasonic detectors communicating with each other and infrared digital imager;
[0042] The ultrasonic detector perceives the difference in the ultrasonic energy field caused by the defective disease, and converts the wave signal into an electrical signal and transmits it to the infrared digital imager. The infrared digital imager obtains the spatial orientation information of the defect source according to the obtained electrical signal, and the Transient image acquisition of defective lesions.
[0043] Specifically, during the operation period, the spandrels on both sides of the railway tunnel are equipped with monitoring equipment integrating high-precision ultrasonic detectors and high-defini...
Embodiment 2
[0055] Embodiment 2 of the present disclosure provides a non-contact railway tunnel lining defect monitoring and early warning method, including the following steps:
[0056] Obtain real-time information on the spatial orientation and image information of the defect source from the monitoring equipment deployed at the spandrel position on the inner wall of the tunnel;
[0057] According to the obtained information, judge the damage degree of the lining falling block, and when the damage degree is greater than the preset threshold, send the alarm information and the defect source location information to the monitoring terminal and / or the train control terminal and / or the cloud server.
[0058] specific,
[0059] (1) Install monitoring equipment. The railway tunnel lining disease monitoring equipment is installed at the spandrels on both sides of the railway tunnel, and the monitoring equipment is installed sequentially along the tunnel axis at intervals of 15 meters, so as to ...
