Problems solved by technology

The rapid development of China's transportation and automobile industry has made people pay more and more attention to the safety performance of automobiles. The research on passive safety of automobiles mainly focuses on collisions, body protection pedestrian devices, and advanced occupant restraint systems. Facing the increasingly prominent social problem of automobiles falling into the water , some car companies have also begun to pay attention, but have not released the relevant detection system for falling into the water. In view of the continuous falling into the water, it is urgent to design a set of detection system with application value

Abstract

The invention discloses a vehicle water-falling detection system based on multi-source information. The vehicle water-falling detection system comprises an ultrasonic water depth detector, humidity sensors, pressure sensors, a speed sensor, an image recognition module and a main control chip. A detection method comprises the steps that the water depth is first detected by using the ultrasonic water depth detector, and when the water depth is less than 0.3m or more than 0.4m, information is sent to the main control chip through the output end of the ultrasonic water depth detector, and the maincontrol chip judges a water falling state of a vehicle, thereby determining whether to open airbags or not; when the water depth reaches 0.3-0.4m, the main control chip judges the water falling stateof the vehicle through the detection information of humidity and pressure; and if the pressure is less than 5KPa at this time, the humidity and speed need to be subjected to data analysis to determine the water falling state of the vehicle. The detection method can accurately judge the water falling depth of the vehicle, and can avoid the occurrence of false opening of the airbags of the vehicle.The vehicle water-falling detection system and detection method based on the multi-source information can better detect the wading condition of the vehicle, thereby judging whether the vehicle fallsinto water or not; and the system is simple and effective.

Description

technical field [0001] The invention relates to a detection system, in particular to a system and a detection method for detecting vehicle falling into water based on multi-source information. Background technique [0002] In recent years, people's living standards have been improving with the rapid economic development. The number of cars in my country has continued to increase. Cars have entered ordinary households as household consumer goods. The accompanying traffic accidents have remained high, and driving safety issues have become increasingly severe. Due to the different driving road environment and technical conditions of cars, traffic accidents manifest in various forms, severe weather intensifies, drivers' safety awareness is weak, and tragedies of cars falling into water occur from time to time, resulting in huge losses of people's lives and property, property and life damage Serious threat, especially for the elderly and children and those who cannot swim, the ch...
