Description

TECHNICAL FIELD

[0001] The utility model relates to non - motor vehicle lane monitoring technical field especially based on YOLOv9's non - motor vehicle lane safety monitoring system. BACKGROUND

[0002] With the increasingly busy city traffic, the popularity of non - motor vehicles, especially electric vehicles, is the increasingly prominent road safety problem. The phenomenon of not wearing a helmet when riding an electric vehicle is common, which undoubtedly increases the risk of injury in traffic accidents. In order to improve the safety awareness of non - motor vehicle drivers and reduce the incidence of traffic accidents, non - motor vehicle lane safety monitoring system emerges as the times require.

[0003] According to statistics, motorcycles, electric bicycles and cars are the vehicles that cause the most deaths in traffic accidents. Among the motorcycle and electric bicycle driving personnel death accidents, about 80% are caused by craniocerebral injury. When the accident occurs, the safety helmet can absorb most of the impact force, and play a buffering and shock - absorbing protective role. According to relevant research and statistical data, correct wearing of safety helmet can reduce the injury rate of non - motor vehicle drivers and passengers by 70%, and the mortality rate by 40%. The head injury rate of non - helmet wearers is 2.5 times that of helmet wearers, and the fatal injury rate of non - helmet wearers is 1.5 times that of helmet wearers. For non - motor vehicle drivers, the helmet is equivalent to the safety belt of car drivers, and is the last line of defense for non - motor vehicle drivers in danger.

[0004] Safety starts from the head. Wearing a safety helmet is not only related to the safety of cyclists, but also related to public traffic safety. With the popularity of shared electric bicycles, the Ministry of Public Security has previously launched a "one helmet and one belt" safety protection action across the country, and has lawfully rectified the behavior of motorcycle and electric bicycle riders not wearing safety helmets and car drivers not using safety belts. Article 51 of the Road Traffic Safety Law of the People's Republic of China: When a motor vehicle is driving, the driver and the passenger shall use safety belts as required, and the motorcycle driver and the passenger shall wear safety helmets as required. Article 90: The driver of a motor vehicle shall comply with the provisions of the Road Traffic Safety Law of the People's Republic of China on road traffic, and shall be punished by warning or a fine of 20 to 200 yuan. If there are other provisions in this law, the punishment shall be in accordance with the provisions.

[0005] The non-motor vehicle helmet wearing detection device for intelligent traffic based on face detection disclosed in Chinese Patent CN213545531U is fixedly installed with a main vertical rod on the left side at the rear end of the motor vehicle lane, a connecting horizontal rod is fixedly connected to the front end of the upper part of the main vertical rod, and a face recognition device is fixedly installed at the lower end of the connecting horizontal rod directly above the motor vehicle lane, and the face recognition device is used to detect whether a helmet is worn or not. However, the present inventor found at least the following technical problems in the process of implementing the technical solution of the present application in the embodiments: 1. The existing detection device is difficult to be associated with the database of the traffic department, which is not conducive to the record of illegal behavior; 2. The above-mentioned detection device structure is copied and fixed in a certain position, so the cost is high. Due to the cost, it is usually only fixed on the main traffic road, but for other traffic roads with a large number of non-motor vehicles, it is usually difficult to arrange. At present, for other traffic roads with a large number of non-motor vehicles, temporary inspection by traffic management personnel such as traffic police is usually used, which greatly wastes police forces.
