Intelligent highway accident perception and intelligent induction security device and method

Abstract

The invention discloses an intelligent highway accident perception and intelligent induction security device and method. The device comprises an accident perception module which is used for perceiving vibration generated by collision of a guardrail to generate a collision vibration electric signal and receiving sound generated when a traffic accident occurs to generate a collision sound electric signal. The device further comprises a communication module, a positioning module, a power supply module, a data memory, a processor module and an anti-disassembly shell. The collision vibration electric signal or the collision sound electric signal are transmitted to the processor module, and the processor module executes an instruction stored in the data memory to judge and execute whether the collision vibration electric signal, the collision sound electric signal and the position data are sent to a cloud server or not through the communication module. According to the intelligent highway accident perception and intelligent induction security device and method, a highway monitoring center can directly or indirectly master and know the current position of a highway, the road condition of a district and the condition of an accident scene in an extremely short time.

Description

technical field [0001] The invention relates to the technical field of expressway facilities, in particular to a smart expressway accident perception and intelligent induction security device and method. Background technique [0002] In the early stage of large-scale construction of domestic expressways, in order to ensure the smoothness of the road sections and driving safety, all expressway sections generally adopted a 24-hour uninterrupted patrol system. In addition to collecting relevant traffic information in a timely manner, patrol personnel must deal with the situation on the spot when necessary. Due to the limitations of information technology and economic conditions at that time, in order to complete the task of "guaranteeing smooth flow and preventing security", we could only adopt such a primitive method. [0003] Chinese patent CN107604853B discloses an intelligent highway guardrail collision device and its control method, which realizes the effect of timely d...

Problems solved by technology

[0004] 1. In order to prevent false alarms, it collects and recognizes images to judge whether there is a real accident or assists in judgment through the change of a certain section of traffic flow. However, in actual implementation, the use of high-definition image acquisition cameras will greatly improve Cost, high-density paving does not have a cost advantage, and low-density paving cannot achieve accurate perception of the entire road section; the image acquisition effect of using a general camera is poor, and who will judge whether there is an accident through the recognition image does not give specific instructions

At the same time, there are many problems in judging whether there is an accident based on the change of traffic flow. Now the traffic flow is generally counted by sensors or cameras installed on the gantry installed on several highways on the expressway. Generally, it only stretches for several highways. Only traffic jams can perceive the difference through the dynamic monitoring of traffic flow. Compared with the occurrence of traffic accidents, traffic jams are lagging behind, and traffic jams may be difficult to occur even if vehicles crash into guardrails on low-flow sections of expressways; due to the existence of the above defects, this Patents cannot effectively improve the accuracy of judgment in the actual implementation process

[0005] 2. It can only perceive the collision signal after the vehicle hits the guardrail, that is to say, it can only judge the accident that the car hit the guardrail, and cannot identify the accident that did not hit the guardrail, such as a car crash, a car that hit an intruder but did not hit the guardrail accidents, etc.
