Remote monitoring device, system and method for recognition of seat occupying and safety belt buckling in automobile

Abstract

The invention relates to a remote monitoring device, system and method for recognition of seat occupying and safety belt buckling in an automobile. The device comprises a seat occupying detection component, a safety belt buckling detection component, a signal processor, an intelligent alarm terminal and a far-end data platform, and according to the situation whether or not a seat occupying recognition sensor detects the pressure, temperature even heart rate and body dynamic signals, whether or not a passenger sits on a seat can be judged firstly; under the premise that the passenger sits on the seat, a first piezoelectric sensor on a safety belt can only detect the heart rate and respiration signals of the passenger under the condition that the passenger who sits on the seat buckles the safety belt, if the heart rate and the respiration signals of the passenger are detected, the passenger buckles the safety belt, otherwise the system can give an alarm to remind the passenger to buckle the safety belt, the judgment is accurate, and counterfeiting is not conducted easily; meanwhile, the system is in communication with the far-end data platform to form remote monitoring, the system helps a passenger transportation center and a traffic police department to monitor the safety belt buckling condition of the passenger in the automobile in real time, the relatively high use ratio of the safety belt in the automobile is guaranteed, and the system helps to guarantee the life safety of the passenger.

Description

technical field [0001] The invention belongs to the technical field of automobile safety, and in particular relates to a remote monitoring device, system and method for automobile seat occupancy and safety belt buckle identification. Background technique [0002] With the advancement of science and technology and the improvement of people's living standards, cars are used by more and more people as a means of transportation, and more and more cars cause road traffic accidents to occur more and more frequently; thus, "safety" has become It is the number one consideration for the driver and occupants and one of the most important features of a car. Seat belts, as the basic protective device to protect drivers and passengers during a car collision, play a vital role in reducing or even avoiding passenger injuries and protecting the lives of passengers. [0003] At present, although it is mandatory to wear seat belts, and each seat is equipped with seat belts, usually, the util...

Problems solved by technology

[0003] At present, although it is mandatory to wear seat belts, and each seat is equipped with seat belts, under normal circumstances, the utilization rate of seat belts is low, and the driver cannot know whether the rear passengers are wearing seat belts

Especially for large-scale long-distance buses, due to the large number of seats, it is impossible to judge whether all passengers are wearing seat belts within the driver's line of sight; A car accident may cause a large number of passenger casualties; the driver cannot know the situation of the passengers wearing seat belts in real time, and the passenger transport center and the traffic police department cannot know whether the rear passengers have buckled the seat belts, which is not convenient for traffic management and passengers. guarantee of life safety

[0004] At the same time, there is also a system that provides an alarm reminder for the requirement of wearing a seat belt, that is, when the passenger does not wear a seat belt, the system will send a reminder to the driver, and then the driver will remind the passenger to wear a seat belt; detect whether there is a passenger on the seat The ride is triggered by the pressure sensor switch. If the pressure sensor switch is broken, the seat needs to be disassembled to remove the skin, and then sewed back after installation. It is very troublesome to replace

Moreover, if a sheet is inserted into the seat belt seat, but the seat belt is not actually inserted into the seat, it will cause the passenger not to fasten the seat belt, and the system will not issue a prompt. The default passenger seat belt has been fastened, which will reduce driving The vigilance of the passengers; the passenger transport center and the traffic police department can not know whether the passengers in the rear row have fastened their seat belts
