In-vehicle emergency alarm system and method

Abstract

The invention relates to the field of automotive electronic technologies, in particular to an in-vehicle emergency alarm system and method. The in-vehicle emergency alarm system comprises a vehicle-mounted terminal, an alarm server and mobile equipment, wherein the vehicle-mounted terminal, the alarm server and the mobile equipment are connected in sequence. The vehicle-mounted terminal is connected with a vehicle bus. A door / window locking state signal acquisition module is used for acquiring door / window locking state information and sending the door / window locking state information to an alarm situation analyzing module. According to the in-vehicle emergency alarm system and method provided by the invention, an alarm message is sent out in time when a person is trapped in a vehicle so that the person can be rescued as soon as possible, and the rescuing efficiency is greatly improved. According to the in-vehicle emergency alarm system, all modules are designed scientifically and reasonably, whether an alarm situation occurs or not can be accurately judged, the severity level of the alarm situation is judged, corresponding handling measures are taken, and rescuing is achieved effectively. Particularly, suffocation accidents frequently occur during summer vacation per year due to the fact that children are trapped in vehicles, the in-vehicle emergency alarm system and method can effectively pre-warn most accidents, and thus the accidents are avoided.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to an in-vehicle emergency alarm system and an alarm method. Background technique [0002] The increasing popularization of automobiles in ordinary families makes the problem of automobile safety (including the safety of people and vehicles in driving, and the safety of people and vehicles in static conditions) more and more serious. Some car alarm systems currently in use (such as ecall) use sensors to detect collisions, and then automatically dial a phone to an emergency center for positioning and rescue through GPS. For example, the invention patent with application publication number CN101357615A discloses an alarm system for leaving people in a car, including a pyroelectric infrared detection module, an automobile door lock switch signal acquisition module, an automobile engine switch signal acquisition module, a power supply voltage stabilization module, a digit...

AI Technical Summary

Problems solved by technology

[0003] The same kind of static car security alarm products or solutions mostly install complex temperature sensors, sound sensors, image sensors and infrared human body induction sensors in the car. The hardware cost is very high and these devices seriously affect the car's function consumption

At the same time, in the existing vehicle alarm system, a new APP is often developed according to the characteristics of the alarm system itself. The user must install the APP and the APP is in the open state to receive the alarm information.

At present, there are many accidents in which children are forgotten in school buses every year, regardless of developed countries or developing countries in the world. In addition, especially during the summer vacation, due to family negligence, accidents of children forgotten in family cars occur frequently. In the final analysis, there is no one Versatile, inexpensive, and easy-to-implement alarm solution
