Description

Technical Field

[0001] The invention relates to the field of tire monitoring, and in particular to a tire tread anti-extrusion system using state analysis. Background Art

[0002] Tires are circular elastic rubber products that roll on the ground and are installed on various vehicles or machines. They are usually installed on metal rims, can support the vehicle body, buffer external impacts, achieve contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperature effects when driving, so they must have high load-bearing performance, traction performance, and buffering performance. At the same time, they are also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation.

[0003] It can be seen that for vehicle safety, tires are the parts that are most directly in contact with the complex ground and need to be monitored. However, the existing tire monitoring mechanism mainly focuses on the scene where the vehicle is driving normally on the road, but lacks a reliable and effective tire monitoring mechanism for the parking scene where the vehicle is parked in a suspended parking space base, which easily causes the tire tread to be squeezed with the side blocking piece of the seat, resulting in multiple damage to the tire tread. Summary of the invention

[0004] In order to solve the technical problems in the related fields, the present invention provides a tire tread anti-crushing system using state analysis, which can determine that a certain pixel point in the received spatial domain enhanced image is a single pixel point constituting the image area of ​​the tire tread in the received spatial domain enhanced image when the brightness value of the certain pixel point is within the color imaging characteristics corresponding to the tire tread, and so on, complete the inspection of the respective image areas of the tire tread and the side blocker of the seat in the spatial domain enhanced image, and when the overall depths of field corresponding to the two image areas where the tire tread and the side blocker of the seat are respectively located match and there is an overlap between the two image areas, a first signal is issued. An identification command is issued to determine whether the tire tread is in contact with the side blocking piece of the vehicle seat. Otherwise, a second identification command is issued to determine whether the tire tread is separated from the side blocking piece of the vehicle seat, thereby realizing intelligent analysis of the relative states of different targets, and executing a voice playback operation corresponding to the tire squeeze warning information when the first identification command is received, and also for stopping the voice playback operation corresponding to the tire squeeze warning information when the second identification command is received, thereby realizing parking assistance control based on a high-precision analysis result of the contact state of the tire tread with the side blocking piece of the vehicle seat, and avoiding multiple damages to the tire tread caused by the squeeze between the tire tread and the side blocking piece of the vehicle seat.

[0005] According to the present invention, there is provided a tire tread anti-crushing system using state analysis, the system comprising:

[0006] A load measuring device is arranged directly below the base of the suspension seat corresponding to the parking space, and is used to measure the real-time load weight of the suspension seat, and to issue a scene monitoring request when the real-time load weight obtained by measurement is greater than or equal to a preset weight threshold, and to issue a monitoring suspension request when the real-time load weight obtained by measurement is less than the preset weight threshold, wherein the suspension seat includes two seat side blocking members on left and right sides and a base arranged between the two seat side blocking members;

[0007] A dynamic capture device, arranged just above the suspension seat and connected to the load measurement device, for starting an imaging action on the suspension seat upon receiving the scene monitoring request, so as to obtain and output a corresponding parking scene image;

[0008] A directional sharpening device, connected to the dynamic capture device, for sequentially performing horizontal sharpening processing and vertical sharpening processing on the received parking scene image to obtain and output a corresponding directional sharpened image;

[0010] A content enhancement device, connected to the signal filtering device, for performing image spatial domain enhancement processing on the received instant filtered image to obtain and output a corresponding spatial domain enhanced image;

[0011] A visual identification device connected to the content enhancement device, for extracting an image area of ​​the tire tread in the received spatial domain enhancement image according to color imaging characteristics corresponding to the tire tread, and extracting an image area of ​​the seat side blocker in the received spatial domain enhancement image according to color imaging characteristics corresponding to the seat side blocker, and issuing a first identification command to determine that the tire tread and the seat side blocker are in contact when the overall depths of field corresponding to the two image areas are matched and the two image areas are superimposed, otherwise, issuing a second identification command to determine that the tire tread and the seat side blocker are separated;

[0012] a voice broadcasting device, arranged on the suspension crossbar of the suspension seat and connected to the visual identification device, for executing the voice broadcasting operation corresponding to the tire squeeze warning information upon receiving the first identification command, and for stopping the voice broadcasting operation corresponding to the tire squeeze warning information upon receiving the second identification command;

[0013] Among them, the visual identification equipment is used to extract the image area of ​​the tire tread in the received spatial domain enhanced image according to the color imaging characteristics corresponding to the tire tread, including: when the brightness value of a certain pixel point in the received spatial domain enhanced image is within the color imaging characteristics corresponding to the tire tread, judging that the certain pixel point is a single pixel point constituting the image area of ​​the tire tread in the received spatial domain enhanced image.
