Description

Technical Field

[0001] The present invention relates to the technical field of tire pressure monitoring, and in particular to a split-type intelligent tire pressure monitoring and early warning system. Background Art

[0002] Tire pressure monitoring refers to a technology that automatically monitors the air pressure of automobile tires in real time and promptly issues an alarm when the tire pressure is abnormal to ensure driving safety. Tire pressure monitoring is an important part of automobile safety performance. Drivers should pay attention to the importance of tire pressure monitoring and check tire pressure regularly to ensure driving safety;

[0003] During the tire pressure monitoring process, the tire pressure monitoring and warning system is needed to detect abnormal tire pressure in time and send warning information in time.

[0004] The existing tire pressure monitoring and warning system has a low level of intelligence in monitoring and warning. Although the new vehicles produced now are equipped with tire pressure monitoring times, there are still a large number of old vehicles that are not equipped with tire pressure sensors. Users of old vehicles can only blindly choose tire pressure sensing equipment to monitor tire pressure. The selected sensing equipment may not be suitable for the driving environment of their vehicles, and problems with the tire pressure monitoring equipment itself cannot be discovered in time, which has a certain impact on the use of the tire pressure monitoring and warning system. Therefore, a split intelligent tire pressure monitoring and warning system is proposed. Summary of the invention

[0043] Then, a preset mark on the external tire pressure sensor is identified, and after the preset mark is identified, the real-time mark area is collected to obtain the second parameter;

[0044] Then, the distance between the standard preset calibration object and the external tire pressure sensor and the initial area of ​​the preset mark collected when the external tire pressure sensor is installed are collected to obtain the standard distance and the standard area;

[0045] Calculate the difference between the first parameter and the standard distance to obtain the first evaluation parameter, calculate the difference between the second parameter and the standard area to obtain the second evaluation parameter;

[0046] The first evaluation parameter and the second evaluation parameter constitute a real-time evaluation parameter.

When there is speed difference information exceeding a preset range among the six speed difference information, the tire pressure difference value of the two wheels corresponding to the speed difference is extracted. When the tire pressure difference value of the two wheels corresponding to the speed difference is greater than a preset value, a tire pressure warning message is generated.

When the tire pressure warning information is generated at this time, an abnormal route confirmation information is sent to the user. When the user confirms that it is an abnormal section of the road, no information is generated. When the user confirms that it is a non-abnormal route, a split equipment abnormal information is generated for prompting.

[0057] The beneficial effects of the present invention are embodied in:

[0058] The split-type intelligent tire pressure monitoring and warning system can intelligently push the type of tire pressure sensor that needs to be set to the user according to the different types of vehicles and uses of the users, thereby avoiding the user's blind selection of tire pressure sensors, resulting in the selected tire pressure sensors not being suitable for the actual use environment of the vehicle and accidents caused by poor tire pressure monitoring accuracy. At the same time, according to the different types of selected tire pressure sensors, the tire pressure is monitored intelligently, and it can detect abnormal tire pressure in a variety of complex situations in a timely manner, and then generate tire pressure warnings in a timely manner to better ensure driving safety.
