Intelligent early warning system for preventing pileup on highway

Abstract

The invention discloses an intelligent early warning system for preventing a pileup on a highway. The intelligent early warning system comprises a vehicle-mounted terminal and a server, wherein the server is used for storing, calculating and analyzing data; the vehicle-mounted terminal is composed of a power supply management module, an embedded processor, a satellite positioning module, a mobile communication module, a ZigBee wireless communication module, a fatigue driving detection module, a vital sign detection module, a brake detection module, an acceleration detection module, a tire pressure detection module, an oil tank temperature detection module, a dangerous goods transportation reminding module, a liquid crystal display module and a voice prompt module, and a vehicle is in communication with nearby vehicles by automatically establishing a Zigbee wireless network and has access to the server through a mobile communication network. The intelligent early warning system has the functions of highway fatigue driving early warning, driver sudden illness early warning, emergency braking early warning, brake failure early warning, tire pressure abnormity early warning, oil tank overtemperature early warning, dangerous goods transportation one-key reminding and the like on the basis of the Internet of Things, drivers are reminded to take related measures in advance in a safe distance so that collision with vehicles having potential safety hazards can be avoided, and a pileup accident on the highway is prevented effectively.

Description

technical field [0001] The invention belongs to the field of traffic safety, and in particular relates to an intelligent early warning system for preventing serial collisions on expressways based on the Internet of Vehicles. Background technique [0002] With the rapid growth of the number of automobiles in my country and the rapid development of expressway construction, by the end of 2013, the total mileage of expressways in my country had reached 104,000 kilometers, surpassing the United States and ranking first in the world. Traffic accidents such as serial collisions on expressways are often reported in the news. Due to the high speed and strong impact, once a traffic accident occurs, the consequences will be extremely disastrous, especially when a passenger car collides with a large truck, it is very easy to cause a large number of casualties Vicious traffic accidents, the hazards and economic losses caused by such traffic accidents are usually several times or even ten t...

Problems solved by technology

[0004] In recent years, some automobile anti-collision modules or systems have been disclosed. For example, in the Chinese invention patent No. ZL200820177711.6, an automobile tire pressure monitoring system based on wireless sensors and CAN bus is disclosed, which proposes to solve the problem of automobile tire burst or The accident caused by the rollover that may be caused by air leakage, but the factors considered are relatively single, which cannot meet the requirements of the early warning system for preventing serial collisions on high-speed roads; in the Chinese invention patent No. ZL201010620675.8, a human-based Intelligent traffic safety system for situation recognition, through the electronic equipment installed on the car to identify the driver's fatigue state, coercion state, drinking state and whether the driver is a legal driver's personal information, so as to ensure traffic safety, but for expressways In terms of driving safety, driver fatigue driving, sudden acute illness while driving, continuous driving without rest for a long time, brake failure, sudden braking, driver drinking and driving, tire burst or air leakage, and spontaneous combustion caused by excessive fuel tank temperature Factors such as explosions, chemicals, or flammable and explosive dangerous goods are the main reasons for serial crashes on expressways. If the problem of data exchange between vehicles can be solved, early warning information can be provided for drivers, so that Knowing the potential safety hazards of other vehicles in advance, and taking appropriate measures at a safe distance can avoid serial collision accidents. The design of the present invention is based on this
