Multifunctional driving monitoring early warning system based on mobile terminal

Abstract

The invention discloses a multifunctional driving monitoring early warning system based on a mobile terminal. According to the multifunctional driving monitoring early warning system, data are collected through four wide-angle cameras arranged on a front grating, a left side door mirror, a right side door mirror and a tail door of a vehicle respectively; then, the data are synthesized to form a complete image through the image processing technology; meanwhile, after electronic power-assisted steering data in an ECU of a vehicle and related working condition information of other vehicles are collected through an OBD2 port data collector which is connected to the ECU of the vehicle and comprises a main chip, namely, an eml327 chip, a 2.4 G module and other related circuits, the data are transmitted to a controller through the 2.4 G wireless technology; advancing trajectory prediction of the vehicle is calculated according to other data, including the axle base, the wheel tread and the like, of the vehicle; finally, the image where trajectory prediction is conducted is outputted to the mobile terminal device such as a mobile phone in a wireless mode, and the data are displayed through the mobile terminal device. According to the multifunctional driving monitoring early warning system, real-time image transmission and detection are achieved through a wireless communication method at a low cost.

Description

technical field [0001] The invention relates to a vehicle track prediction, monitoring and early warning system, in particular to a mobile terminal device-based panoramic overlooking driving monitoring and early warning system with driving track prediction. Background technique [0002] With the development of society, the problem of traffic safety has become more and more prominent, and the traditional concept of automobile safety is gradually changing. Traditional safety measures such as seat belts, airbags, bumpers, etc., are mostly passive after the accident. The way to carry out post-event remedial measures cannot effectively solve the occurrence of traffic accidents. With the advancement of science and technology, the increase of traffic pressure, the safety awareness of vehicle driving is constantly improving, and the active safety warning system is gradually becoming a new field accompanied by the rapid development of the automobile industry. [0003] As...

AI Technical Summary

Problems solved by technology

[0005] Disadvantages of existing radar detection: In the current implementation of radar detection, a new radar module is specially added for the lane change warning system, which increases the installation cost and hardware investment cost

In addition, when there is a lane change danger warning, it is only prompted by the flashing signal light on the instrument panel, and the prompt method is not obvious and clear

[0006] Disadvantages of lane change warning based on image recognition: There are many prerequisites for the lane change warning method based on image recognition, and the requirements for the environment and road conditions are very high. The correct judgment of the lane, let alone the realization of danger warning

The program is not practical
