On-vehicle automatic asking-for-help system

Abstract

The invention discloses a vehicle-mounted automatic rescue system, comprising: a microcontroller, a data acquisition circuit, a CAN bus interface circuit, an isolation circuit, a communication module and a GPS module; the data acquisition circuit is used to collect the physical sign information of drivers and passengers; The interface circuit is used to obtain the current driving state information of the vehicle; the microcontroller is used to compare the sign information and the driving state information with a preset threshold to determine whether the vehicle has a traffic accident; and when it is determined that the vehicle has a traffic accident, The GPS module is controlled to obtain the current location information, and the communication module is controlled to send the distress information including the location information to the remote device, so as to ask for help from the outside world. Adopting the embodiment of the present invention can solve the problem of automatic help-seeking of drivers and passengers in traffic accidents, reduce the casualty rate, and improve the survival rate.

Description

technical field [0001] The invention relates to the technical field of vehicle equipment, in particular to a vehicle automatic rescue system. Background technique [0002] Cars are prone to various traffic accidents during high-speed driving, such as car spontaneous combustion, multi-vehicle serial collision, falling into water, entrapment of drivers and passengers, etc. However, there are no related equipment and technologies for cars to automatically call for help. When the above situation occurs, the drivers and passengers need to ask for help by themselves, but because everyone's self-rescue quality is not the same, it is easy to cause casualties. Therefore, need a kind of system that calls for help automatically in critical moment, helps the trapped driver and crew to call for help. Contents of the invention [0003] The embodiment of the present invention proposes a vehicle-mounted automatic emergency call system, which can solve the automatic emergency call for hel...
