Problems solved by technology

Due to the existence of blind spots, turning vehicles are prone to hit pedestrians
[0003] At present, the ghost probe traffic accident monitoring system in the prior art is relatively simple. It usually only judges whether there is a person in front of the vehicle. The function of monitoring and early warning with the vehicles behind

Embodiment 1

[0038] Such as figure 1 As shown, a ghost probe traffic accident early warning system is installed on a vehicle for monitoring, identifying and early warning of people in front and rear vehicles; a vehicle equipped with the early warning system is called a current vehicle; the early warning system It includes a monitoring module 1 and a prevention module 2, and data transmission is performed between the monitoring module 1 and the prevention module 2 through the CAN bus module 3;

[0039] Monitoring module 1 comprises from single-chip microcomputer 11, and is respectively connected with described image acquisition unit 12 and radar acquisition unit 13 from single-chip microcomputer 11; Wherein:

[0040] Image acquisition unit 12 comprises at least one camera, and described camera is arranged on the front end of current vehicle (in the present embodiment, selects 1 camera for use, is placed in the front center of bus); Image acquisition unit 12 is used for real-time acquisition...

Embodiment 2

[0058] A method for early warning of traffic accidents with ghost probes, such as Figure 10 with Figure 11 shown, including the following steps:

[0059] Step S1, using the image acquisition unit 12 to collect the environmental image in front of the current vehicle in real time, and transmitting the collected environmental image to the slave microcontroller 11; at the same time, using the radar acquisition unit 13 to sense the front and rear of the current vehicle in real time Whether there is an object within the preset distance range, and calculate the distance data between the object behind the current vehicle and the rear end of the current vehicle in real time.

[0060] The specific working process of step S1 includes: using a trigger pulse from the IO port of the single-chip microcomputer to the radar sensor, the radar sensor automatically sends 8 square waves of 40KHZ, and the radar sensor automatically detects whether there is a signal return, and if there is a sign...

Abstract

The invention provides a ghost probe traffic accident early warning system and -method. The early warning system mainly comprises a monitoring module and a prevention module. The monitoring module andthe prevention module transmit data through a CAN bus module. The monitoring module is used for real-time monitoring whether there are objects in the preset distance range in the front and rear of the current vehicle, and measuring the distance data and the speed data between the object behind the current vehicle and the rear end of the current vehicle, and then transmitting the information to the prevention module;. According to the received information, the prevention module controls the character display unit, the voice playing unit and the prompt light unit to work, to alarm and remind, thereby reducing the occurrence of the ghost probe traffic accident, and improving the safety of the road traffic.

Description

technical field [0001] The invention belongs to the technical field of traffic safety control, and in particular relates to a ghost probe traffic accident early warning system and method. Background technique [0002] "Ghost probe" is a common saying in traffic safety accidents. It usually means that when car A overtakes car B (also means that car A is on the way, the vehicles on both sides or the vehicle B on one side are in a static state), because the line of sight of car A is blocked by the vehicle. Or obstacles block, pedestrians or vehicles suddenly run out of blind spots such as the front of the B car, the rear of the oncoming vehicle, or the buildings on both sides of the road. This phenomenon makes it difficult for driving drivers to judge in advance, often causing traffic accidents. Large vehicles are high-risk locations for "ghost probe" accidents. For example, when a bus stops at a stop, pedestrians in front of the vehicle and vehicles behind the vehicle are pro...
