Device and method for vehicle fault location and fault information transmission

The invention relates to a vehicle fault sign, in particular to a device and method for vehicle fault ranging and fault information transmission.

According to Article 12, Item 12 of the Road Traffic Safety Rules: If the car fails to drive, it should be moved to the place where there is no obstacle to traffic. The faulty vehicle should be erected with a vehicle fault sign (such as a triangular cone warning) before or after displacement. The sign should be erected on the road at a speed of 40 km/h from 5 m to 30 m behind the vehicle. The road at a speed of more than 40 km should be erected 30 m to 100 behind the vehicle. On the road of the meter, the section of traffic congestion should be hung from the back of the body. The proper position in front of the car depends on the need to be set. When the vehicle leaves the site, it should be removed.

Accordingly, when the driver suddenly fails during the running of the vehicle, the vehicle fault flag must be installed at an appropriate distance behind the vehicle to ensure that the road driving of the other vehicle driver is safe and the vehicle is placed behind the faulty vehicle. The distance of the sign is not enough to be very important, and it may even affect the judge’s conviction and innocence.

It has been reported that the 39-year-old man surnamed the man was arrested on the inner lane at the national highway No. 1 at the National Highway No. 1 in November 1997. He was asked to help the tow crane to assist the towing crane, although the two had placed a triangular cone. Warning, but still chased by Xiao’s truck driver who was drunk in the rear, Xiaomou died. The first-instance judge held that the two people were placed in a warning distance that was not related to the law, and that two people were sentenced to four months in prison for negligent death.

Another report pointed out that on the evening of February 2, 1997, when Li’s towed driver was carrying a trailer accident on a car accident in Zhudong Yuanshan Road, there was also a drunken Xu man riding a locomotive from the rear. The doctor was surrendered. The driver of the surname Li was prosecuted for the crime of negligent death. However, the judge of the first instance thought that Li had set up a warning light and placed a triangle cone with sufficient distance to think that Li was not guilty of negligence.

When there is a vehicle failure, car accident or other emergency in the expressway or expressway, the owner should first turn on the direction light, gradually slide the vehicle off the lane and stop on the shoulder, then turn on the danger warning light and in the vehicle. A vehicle fault sign (such as a triangular cone) is erected 50-100 meters behind to alert the rear vehicle. If the vehicle cannot slip off the lane, in addition to displaying the hazard warning light, the vehicle fault sign should be set more than 100 meters behind the faulty vehicle, and the police should be notified immediately for assistance. However, when an ordinary person drives a car in a fault or a car accident, although the vehicle fault warning sign is placed behind it, the distance does not meet the above-mentioned relevant regulations, resulting in the rear vehicle being evaded and causing chasing, resulting in casualties of the second accident. Therefore, it is very important to set the distance of the vehicle fault sign. In the event of an accident, it may even affect the judge's conviction or innocence!

In addition, in the past, when the car accident occurred, the car owner rushed to explore the injured person's injury, and could not immediately inform the police to assist in the handling. The police could not confirm the correct location of the car accident at the first time. The car accident may also cause the traffic speed of the nearby expressway to drop. The police can only wait for the "passive notification" to cope with the accident in the expressway accident. The police response mechanism will not be sent to the scene until the incident is dealt with. However, if the vehicle fails or is in an accident, it can "active" through the wireless network. Inform the police or the road traffic control center to provide immediate ambulance assistance and remind other drivers to pay attention to provide safer transportation.

Automatic positioning and emergency assistance in traffic accidents is the most important function of accident management. Through the in-vehicle detection device communication technology, wireless network technology and global satellite positioning technology, when the car has a safety accident, it will send a help signal to the rescue organization at the first time, and determine the exact location of the car, which will bring great disaster to the rescue work. help.
