Embodiment Construction
[0030] The present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.
[0031] like figure 1 Shown is a system block diagram of a vehicle collision alarm detection method according to an embodiment of the present invention, which mainly includes the following steps:
[0032] S1. Set the collision parameters, including: the first preset time T 1 , the second preset time T 2 , the third preset time T 3 , preset acceleration value K, preset speed value V;
[0033] S2. Collect the real-time acceleration value M and real-time speed value N of the vehicle;
[0034] S3. If at the first preset time T 1 If the real-time acceleration value M of the vehicle exceeds the preset acceleration value K, it means that the suspected collision detection is triggered and enters step S4, otherwise returns to step S2;
[0035] S4, the first preset time T 1 After the end, if the next second preset time T 2 If the vehicle's real-t...

The invention discloses a vehicle collision alarm detection method and a processing system. The method mainly comprises the steps that collision parameters of first preset time T1, second preset time T2, third preset time T3, a preset acceleration value K and a preset speed value V are set; real-time acceleration values M and real-time speed values N of a vehicle are acquired; whether all the real-time acceleration values M of the vehicle exceed the preset acceleration value K within the first preset time T1 is judged; whether the real-time speed values N of the vehicle are reduced to be lower than the preset speed value V within the second preset time T2 is judged, and the real-time speed values N of the vehicle within the third preset time T3 are all lower than V; and finally information of the location of the vehicle, and the maximum acceleration value M and the maximum speed value N acquired within time T1 are transmitted to a third-party monitoring center, and the third-party monitoring center arranges rescue according to the acquired information. Collision detection accuracy can be effectively enhanced by the method and the system so that rate of false alarm can be reduced.
Description
technical field [0001] The invention belongs to the technical field of vehicle information detection, and in particular relates to a vehicle collision alarm detection method and a processing system based on the method. Background technique [0002] With the convenience brought by the development of the automobile industry to people's life and travel, the number of vehicles in the country is increasing every year, but at the same time, accidents are also increasing. Hundreds of thousands of people are killed or killed in car accidents every year, which also brings There came huge property damage. According to statistics from the Ministry of Health, in 1,000 accidents, only 14.3% of the injured could reach the hospital in time for treatment by ambulance, and most of the injured would die due to uncounted rescue. At present, in the field of automobile safety research, although the more and more perfect automobile collision protection system can effectively reduce the death rat...
