Abstract

The invention relates to a secondary starting and rolling accident pre-warning system for a dead zone in front of a slag land vehicle, which comprises a dead zone automatic braking system, a sensing module and a control module, wherein the sensing module is used for collecting real-time vehicle speed, identifying whether pedestrians or non-motor vehicles exist below the vehicle head, detecting whether the vehicle door is opened or not, detecting whether a hand brake is pulled up or not, sending a signal to the control module, the control module is used for analyzing the signal sent by the sensing module and sending a corresponding instruction, and the dead zone automatic braking system is used for receiving and executing the instruction sent by a controller and simultaneously feeding back the execution signal to the controller. After the automatic braking system is triggered, the early warning system can identify whether a pedestrian or a non-motor vehicle exists at the bottom of the locomotive or not before secondary starting of the driver, remind the driver of carrying out safety inspection before secondary starting, and prevent the driver from secondary starting under the condition of potential safety hazards, so that rolling accidents are effectively prevented from occurring in a dead zone in front of the secondary starting of the muck vehicle.

Claims (2)

1. 1. The early warning method for the secondary starting rolling accidents of the dead zone in front of the slag car is characterized by comprising the following steps of: s1, a central controller in a control module receives a signal from whether a dead zone automatic braking system is started or not, if the central controller receives a signal that the dead zone automatic braking system is not started, the self-vehicle continues to run, and if the central controller receives a signal that the dead zone automatic braking system is started, S2 is entered; S2, the central controller analyzes the signal sent by the speed sensor to judge whether the vehicle continues to run or sends a detection instruction to the pedestrian non-motor vehicle detection module, and if the detection instruction is sent to the pedestrian non-motor vehicle detection module, the S3 is entered; S3, a pedestrian non-motor vehicle detection module receives an instruction of the central controller, and a life detection millimeter wave radar detects whether an object in an area below a vehicle head has vital signs or not, a pedestrian image recognition device detects whether a pedestrian exists in a target area, an ultrasonic radar detects whether the pedestrian or non-motor vehicle exists in a non-tire area, and the life detection millimeter wave radar, the pedestrian image recognition device and the ultrasonic radar send detection signals to the central controller and then enter S4; s4, the central controller analyzes the received detection signals and sends out instructions, and S4 comprises the following substeps: s41, the central controller analyzes three detection signals sent by the life detection millimeter wave radar, the pedestrian image recognition device and the ultrasonic radar; If all three detection signals are not met, when the driver restarts, the central controller sends out a brake release signal to the blind area automatic brake system; If any one of the three detection signals is met, the central controller controls the alarm device to send out a voice prompt to the driver to remind the driver to observe whether a pedestrian or a non-motor vehicle exists or not, and sends out a detection instruction to the door opening and closing sensor to enter S42; if any two or more than two of the three detection signals are met, the central controller controls the alarm device to send out acousto-optic early warning and sends out detection instructions to the door switch sensor, and S42 is entered; S42, the central controller receives a detection signal sent by the vehicle door switch sensor, and if no door opening signal is detected when a driver starts for the second time, the central controller sends a braking instruction to the blind area automatic braking system again to enable the self-vehicle to be kept in a braking state and control the alarm device to work continuously, and if the door opening signal is detected, S43 is carried out; S43, the central controller sends a detection instruction to the hand brake detection device, the hand brake detection device detects whether the hand brake is pulled up, if the hand brake is detected to be pulled up, the central controller sends an instruction for releasing the brake to the blind area automatic brake system, the alarm device stops working, and if the hand brake is not detected to be pulled up, the blind area automatic brake system continues to brake, and the alarm device continues to work.
2. 2. The method for early warning of a secondary start rolling accident of a dead zone in front of a slag car according to claim 1, wherein the life detection millimeter wave radar and the pedestrian image recognition device are installed at the position below a car head on the front sides of two front wheels, and the ultrasonic radar is installed at a non-tire area below the car head.

Description

Secondary starting and rolling accident early warning system and method for front dead zone of slag car Technical Field The invention belongs to the technical field of auxiliary driving of a muck truck, and particularly relates to a secondary starting and rolling accident early warning system and method for a blind area in front of the muck truck. Technical Field The residue-soil vehicle is a heavy equipment vehicle for conveying waste materials, and plays a great role in the field of building engineering and urban sanitation. Due to the fact that the cab of the muck truck is high in position and long in truck body, a plurality of visual field blind areas exist in the running process, and safety of traffic vulnerable groups such as pedestrians, non-motor vehicles and the like is seriously threatened. Aiming at the problem, a solution is provided by a slag car right dead zone early warning system of China patent CN201921433225.0, which mainly comprises a central controller, a radar probe, a camera, an alarm device, a brake system, a display screen and the like, and the vision dead zone of the car is monitored through the radar probe and the camera in the driving process. For the soil and slag vehicle with the blind area automatic braking system, although the automatic braking system of the soil and slag vehicle can be started when pedestrians and non-motor vehicles are monitored, when a driver is in a distraction state, the driver can only feel sudden braking and does not notice the pedestrians or the non-motor vehicles, if the pedestrians or the non-motor vehicles are scraped and are involved in the area under the vehicle head, at the moment, the driver cannot see the area under the vehicle head, the blind area automatic braking system cannot monitor the existence of the pedestrians under the vehicle head, the alarm device and the blind area automatic braking system cannot be triggered again, the driver is likely to choose to restart, and serious traffic accidents such as rolling pedestrians or the non-motor vehicles are caused, so the system can effectively prevent primary collision accidents of the vision blind area, and secondary starting accidents in the parking state after primary braking are difficult to prevent.
