Intelligent alarm system and method for expressway car accidents

Abstract

The invention discloses an intelligent alarm system for expressway car accidents, which relates to a distribution type intelligent alarm system. The intelligent alarm system comprises n intelligent car accident alarm devices, wherein n is a positive integer. Each intelligent car accident alarm device comprises a power supply module, an audible and visual alarm, a processor, a car speed detecting module, a wireless monitoring camera and a wireless receiving and sending module, wherein the output end of the car speed detecting module is connected with a first input end of the processor; a first output end of the processor is connected with the input end of the audible and visual alarm; a second output end of the processor is connected with a control signal input end of a wireless monitoring camera; the wireless receiving and sending module is connected with the processor in a bidirectional manner; the power supply module is used for supplying power to the audible and visual alarm, the processor, the car speed detecting module, the wireless monitoring camera and the wireless receiving and sending module. According to the intelligent alarm system and method for the expressway car accidents disclosed by the invention, the expressway car accident pre-warning function is realized, the possibility of tailgating and traffic collision on an expressway is lowered by the greatest extend, and the life safety and the property safety of people can be effectively guaranteed.

Description

Technical field [0001] The invention relates to a distributed intelligent alarm system, in particular to a highway accident intelligent alarm system and method. Background technique [0002] The rapid development of expressways in my country has greatly boosted the development of the national economy and greatly facilitated the people's travel. However, highway accidents happen from time to time, especially in severe weather such as rain, snow, heavy fog, sandstorms, etc. Once a small-scale accident occurs, the vehicles behind cannot foresee the accident in front due to low visibility or slippery roads. Serial car accidents caused heavy losses. In the existing highway alarm system, the alarm method based on bus control may make the entire system inoperable due to the destruction of one node; the early warning system installed in the car needs to be configured for each car, and the cost is high. The internal signal attenuation is more serious; the early warning system that relie...

However, highway accidents happen from time to time, especially in bad weather such as rain, snow, fog, and sandstorms. Once a small-scale accident occurs, due to reasons such as low visibility or slippery roads, the vehicles behind cannot foresee the accident in front, resulting in Serial car accident, heavy loss

In the existing expressway alarm system, the alarm method based on bus control may cause the whole system to fail to work due to the damage of one node; the early warning system installed in the vehicle needs to be configured for each vehicle, the cost is high, and the vehicle The internal signal attenuation is relatively serious; the early warning system that relies solely on the manual mode has defects in the timeliness and reliability of the alarm
