Description
Technical Field
The invention relates to the technical field of vehicle safety protection, in particular to a system for preventing cheating when a motor vehicle safety belt is worn.
Background
The safety belt is a life line of an automobile and plays a role in protecting safety of drivers and passengers. When the automobile runs at a high speed, if the automobile collides or meets the unexpected requirement of emergency braking, the generated huge inertia force can cause the driver and passengers in the automobile to collide with the steering wheel, the windshield and the seat back, thereby generating huge damage.
The traffic accident that usually occurs is mostly a frontal collision. The impact force generated when a vehicle with a speed of 50 km per hour collides with the front is enough to hit a four-story building. In the dummy crash test, the belted dummy can be well protected, and the dummy without the belted dummy directly collides with the windshield. If the collision comes from the right side of the vehicle, an unbelted passenger will hit directly against the driver, resulting in injury to both persons at the same time. It has been shown that without the safety belt, the airbag does not play a significant role. It is particularly important for children to properly tie the harness. Children who do not wear the safety belt will suffer more than 7 times the injury to adults.
At present, many drivers consider that the safety belt is not needed to be fastened under the condition of low vehicle speed, and some people consider that the safety airbag can protect the safety of the driver, so that the safety belt is not needed to be fastened. These ideas are in fact wrong. Without the protection of the safety belt, the safety airbag cannot function at all and even causes greater injury. Meanwhile, even at the daily city driving speed, a sudden head-on collision may cause fatal injury to the unbelted passengers.
The safety belt is taken as an indispensable safety device, but a lot of drivers and passengers pay attention to the safety belt at present, and although a lot of vehicles can make automatic alarm prompts without fastening the safety belt at present, a lot of people use some safety belts to simulate buckles to be inserted into clamping grooves in order to prevent the vehicles from giving alarm prompts, so that the safety belt identification device is shielded.
Therefore, it is highly desirable to develop a more efficient anti-cheating system for wearing motor vehicle seat belts.
Disclosure of Invention

Wherein the distance between the point-type flexible pressure sensors is 0.1-10 cm.
The invention relates to a working method of a motor vehicle safety belt wearing anti-cheating system, which comprises the following steps:
(1) The pressure detection sensors in the backrest area and the hip area of all the seats detect pressure at the same time, and the controller judges whether a person is on the seats or not;
(2) If the person is judged to exist, when the buckle on the seat is not inserted into the clamping groove, the safety belt alarm sensor continuously sends out alarm prompt sounds, and the work indicator lamp displays red;
(3) After the buckle on the seat is inserted into the clamping groove, the RFID anti-metal electronic tag identification device identifies the RFID anti-metal electronic tag in the buckle, if the RFID anti-metal electronic tag identification device and the RFID anti-metal electronic tag are matched, the controller controls the reel of the safety belt to automatically tighten the safety belt, and pressure from the body of a passenger is detected through the point type flexible pressure sensor;
when the controller receives feedback signals sent by at least 3 point type flexible pressure sensors in the safety belt on the seat with the person is judged, the safety belt is judged to be effectively worn;
when the vehicle travels, the controller controls the safety belt reel to automatically tighten the safety belt again at random time, judges whether the point type flexible pressure sensor which sends out the feedback signal when tightening this time is the same as the point type flexible pressure sensor which sends out the feedback signal for the first time, and judges that the safety belt is effectively worn if the point type flexible pressure sensor which sends out the feedback signal for the first time is the same; thus, the escape anti-cheating system for manually rolling or rolling the safety belt can be thoroughly eradicated;
after all safety belts on the seat where a person sits are judged to be effectively worn, the working indicator lamp displays green, and the alarm prompt tone stops; otherwise, the working indicator lamp always displays red, and the safety belt alarm sensor continuously sends out alarm prompt sound.
Compared with the prior art, the invention has the outstanding effects that:
the anti-cheating system for wearing the motor vehicle safety belt can thoroughly avoid the behavior that drivers and passengers escape the safety belt identification device by using the simulation buckles, can always and effectively identify whether the safety belt is tied or not, and can give an alarm prompt, and has the advantages of wide application range, convenient use and remarkable effect.

The RFID anti-metal tag is suitable for adopting a frequency hopping working mode and has super-strong anti-interference capability. The effective reading distance of the RFID anti-metal tag can reach more than 8 meters (related to a reader-writer and an antenna). The RFID anti-metal electronic tag adopts ultra-wide working frequency band design, which not only accords with relevant industry regulations, but also can be flexibly developed and applied. Multiple RFID anti-metal tags (up to 50/s or more) can be read and written simultaneously without being limited or affected by the number of tags in the work area. The memory area is used for the user to read, write, erase and rewrite, and also opens up a permanent special word area special for the appointed user. The RFID anti-metal electronic tag does not need a battery, the memory can be repeatedly erased and written more than 10000 times, the effective service life is more than ten years, and the cost performance is higher.
The RFID anti-metal tag in the system can be an anti-metal hard tag or a flexible anti-metal tag of Shenzhen Sutong Internet of things technology Co.
The point type flexible pressure sensor can select DF9-40 series products of Ningbo and technology limited company, and has the characteristics of flexible waterproof packaging, high sensitivity, wide detection range, high response speed, low power consumption, excellent stability, good biocompatibility and the like.
The above examples are only illustrative of the preferred embodiments of the present invention and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art to the technical solution of the present invention should fall within the scope of protection defined by the claims of the present invention without departing from the spirit of the present invention.
