Embodiment Construction

[0018] like figure 1 shown. The device used in the present invention includes a main control module 1, and also includes an alarm module 2 connected to the main control module 1, an information storage module 3, a short-distance communication module 4, an acceleration sensor module 5, and a GPS information acquisition module 6.

[0019] In the vehicle-mounted terminal device used in the present invention, the main control chip used in the main control module is matched with a certain peripheral circuit to realize the control function of other modules; the alarm module adopts an ordinary buzzer alarm circuit; the short-distance communication module Existing wireless communication technologies, such as WiFi, ZigBee, etc., can be used; the GPS information acquisition module uses a GPS signal receiver, which captures the orbital parameter data of space satellites through the GPS signal receiver, and calculates and parses the user's geographic location within it. The location's la...

Abstract

The invention discloses a vehicle-networking-based highway active anti-collision method. A device mainly comprises a master control module, an acceleration sensor module, a global position system (GPS) information acquisition module, a short-distance communication module, an alarm module and an information storage module. Various modules which are arranged on a vehicle and vehicles around the vehicle on a highway form a temporary mobile Ad-hoc network in real time, and the acceleration, speed, position and other vehicle safety related information of the vehicle are transmitted to realize active anti-collision of the vehicle.

Description

technical field [0001] The invention relates to the field of automobile anti-collision methods, in particular to a highway active anti-collision method based on the Internet of Vehicles. Background technique [0002] Safety measures can be roughly divided into active safety measures (to prevent accidents) and passive safety measures (to reduce the consequences of accidents). Among the existing car safety measures, common passive safety measures include airbags, pre-tensioned seat belts, occupant head and neck protection systems (WHIPS), and Toyota's GOA (Global Outstanding Assessment, the world's top level of safety design) design patents. ; Common active safety measures include AWS anti-collision warning system, TCS traction control system, VSA vehicle stability control system, ABS anti-lock braking system, EDB electronic brake force distribution control system and so on. Among these existing safety measures, they are only limited to the transformation of the mechanical st...
