Embodiment

[0065] Such as figure 1 As shown, an abnormal temperature detection and early warning system for automobile hubs in the present invention is mainly composed of a surveillance camera 1 , an infrared thermal imaging camera 2 , a control host 3 and a variable information intelligence board 4 .

[0066] When the vehicle is running on the road section 5, the monitoring camera 1 located above the road section 5 at the front end of the vehicle takes pictures of it, transmits the image to the control host 3, and sends a signal to the thermal imaging camera 2.

[0067] The infrared thermal imaging camera 2 is located on the roadside, and after receiving the signal, the hub area of ​​the vehicle is photographed, and the thermal imaging image is transmitted to the control host 3 .

[0068] The control host 3 mainly includes the following three functions:

[0069] 1) The control host 3 recognizes and saves the vehicle license plate information in the video frame captured by the surveilla...

Abstract

The invention relates to an automobile hub temperature anomaly detection and early warning method and system. The system comprises a surveillance camera, a thermal infrared imager, a control host and a variable information board. The surveillance camera is installed above a road, the thermal infrared imager is installed on the road side, and the variable information board is arranged on the downstream of the surveillance camera. When a vehicle arrives at a detection area, the surveillance camera and the thermal infrared imager collect images of the vehicle and send the images to the control host; the control host carries out vehicle license plate recognition on the image shot by the surveillance camera; the control host extracts and fuses the SBDD, HOG and LBP features of a hub in the thermal imaging image and then judges whether the temperature of the hub is abnormal or not in a classified mode through an incremental support vector machine; when it is found that the temperature of the hub is abnormal, vehicle information is sent to the variable information board for early warning reminding. By means of the automobile hub temperature anomaly detection and early warning method and system, whether the temperature of the hub of an automobile is abnormal or not can be effectively detected, and early warning can be effectively carried out, so that traffic accidents caused by brake failure, fire breakout, tire burst and the like are avoided.

Description

【Technical field】 [0001] The invention relates to the field of traffic, in particular to a method and system for detecting and warning abnormal temperature of an automobile hub. 【Background technique】 [0002] When the car is braking, the friction between the wheel disc and the brake pads will cause the hub to heat up. Especially when the truck brakes frequently or continuously when it goes downhill or on continuous curves, the temperature of the hub will rise sharply. However, it is difficult for the driver to judge whether the temperature of the wheel hub is too high during the driving of the car, and the temperature of the wheel hub cannot be cooled in time, which will cause a significant decrease in the friction torque of the brake, or even malfunction or fire, leading to safety accidents. [0003] Under normal circumstances, the safety facilities set up by the highway management department to remind trucks to slow down on continuous downhill roads can only serve as remi...
