Problems solved by technology

However, using this method, the evaluation of occupant injury is not accurate, because it does not take into account the difference in the shape of the vehicle when it collides, and the probability and degree of injury of the vehicle and its occupants are different when the shape of the vehicle is different during the collision; Therefore, even if the vehicle shape is the same at the time of the collision, the state of the vehicle occupant is different, such as the occupant's sitting posture is different, and whether the occupant is fastened with a seat belt will also affect the degree of injury
[0004] Therefore, although the use of the existing vehicle-mounted emergency call system can provide certain guidance on the allocation of medical emergency supplies and improve the response speed of emergency rescue, but because the accuracy of the analysis of the occupant's injury is not high enough, the hospital personnel will still be unable to respond after arriving at the scene. It often happens that the prepared rescue plan does not match the actual injury conditions of the occupants, resulting in the effectiveness of the emergency treatment for the injured occupants on the spot cannot be guaranteed, and they still need to go to the emergency center to receive targeted treatment. Emergency time and the injury is aggravated or the effect of treatment is affected

Embodiment 1

[0041]It should be noted that the implementation of this method relies on the backend and the vehicle installed on the vehicle; in this embodiment, the backend is a server; the vehicle is used to collect and send accident data. Such as figure 1 As shown, the trauma risk prediction method for vehicle occupants used in the rapid rescue of traffic accidents includes:

[0042] S0, based on the preset initial parameters, build the basic model of occupant damage analysis. The input parameters of the basic model include vehicle basic data, dynamic boundary data, restraint system execution data and basic occupant data, and the output parameters include human injury simulation data. Specifically, when building the basic model, use the MADYMO software to parametrically edit the features of the simulation model to build a "crew cabin-crew-restraint system" modular simulation model. MADYMO (MAthematical DYnamic MOdel) multi-rigid body dynamics analysis software was originally completed i...

Embodiment 2

[0054] The difference from Embodiment 1 is that in S0 of this embodiment, a verification library is also set and stored in the background end, and the damage level range corresponding to each acceleration curve is stored in the verification library.

[0055] In S3, after the damage analysis result is obtained, the corresponding damage level range is matched according to the acceleration curve. If the damage level in the damage analysis result is not within the damage level range, a re-acquisition signal is sent to the on-board electronic system, and the on-board electronic system receives After re-collecting the signal, re-collect the accident data and send it to the backend.

[0056] If the damage level in the damage analysis result is not within the damage level range, it means that there is a problem in the analysis, for example, a slow acceleration curve has a very high severity damage level. Since the analysis at the backend is based on model analysis, the stability of th...

Embodiment 3

[0058] Different from Embodiment 1, in this embodiment, the acquisition device of the on-board electronic system includes a pressure sensor arranged on the seat and an infrared sensor under the seat; wherein, each seat has a plurality of pressure sensors , a plurality of pressure sensors are evenly arranged on the seat.

[0059] In S1, when obtaining the basic occupant data, if a seat is under pressure and the seat belt is not used, start the infrared sensor under the corresponding seat to analyze the number of legs of the occupant on the seat; if both feet are on the ground, record It is a normal sitting posture. If one foot is on the ground, it is recorded as cross-legged; if both feet are not on the ground, analyze the number and position of the corresponding seats. If there are three seats in the back row, it is recorded as sleeping; otherwise, analyze the Pressure data, if the pressure data is greater than the preset value, it will be recorded as cross-legged, if the pres...

Abstract

The invention belongs to the technical field of traffic accident rescue, and particularly relates to an in-vehicle personnel trauma risk prediction method for traffic accident rapid rescue. The method comprises the following steps: S0, building a basic model for passenger injury analysis based on preset initial parameters, wherein input parameters of the basic model comprise dynamic boundary data, constraint system execution data and passenger basic data, and output parameters comprise human body injury simulation data; S1, acquiring accident data within a preset time before and after a vehicle collision through a vehicle-mounted electronic system, and sending the accident data to a background end, wherein the accident data comprises dynamic boundary data, constraint system execution data and passenger basic data; s2, replacing the initial parameters in the basic model with the accident data, performing vehicle collision simulation analysis, and obtaining human body injury simulation data; s3, performing injury condition analysis according to the human injury simulation data to obtain an injury analysis result. The method can provide accurate rescue guidance for a rescue center.

Description

technical field [0001] The invention belongs to the technical field of traffic accident rescue, and in particular relates to a trauma risk prediction method for people in a vehicle for rapid rescue of traffic accidents. Background technique [0002] After a traffic accident, in order to realize the rapid deployment of rescue plans by traffic law enforcement departments and provide guidance for the precise allocation of medical emergency supplies, a vehicle-mounted emergency call system appeared. [0003] The on-board emergency call system can automatically detect the occurrence of an accident, the location of the accident, the time of the accident, the impact force, the number of occupants, and the injury of personnel through the built-in algorithm and send it to the call center, thereby greatly improving the response rate of emergency rescue. At present, the occupant's injury estimation in the on-board emergency call system is realized by calculating the variation of vehicl...
