Traffic early-warning method, information transmitter, information receiver and traffic early-warning system

Abstract

The invention relates to a traffic early-warning method, an information transmitter, an information receiver and a traffic early-warning system, belonging to the field of traffic safety. The traffic early-warning method, the information transmitter, the information receiver and the traffic early-warning system are automatically or manually or circularly triggered according to time period. Traffic early-warning information is processed and transmitted by technologies, i.e. the information processing, the radio receiving and transmitting, the directive antenna, the broadcast type communication, the relay retransmission, the alarm display and the like. The propagation path can be widened, the propagation mode can be improved, the propagation distance can be prolonged, and the propagation effectiveness and the information initiative can be improved. The sufficient information sharing among main bodies of the road traffic can be realized. The traffic safety early-warning where the abnormal situation does not form the actual danger, the early-warning distance reaches the furthest kilometer level, and the early-warning time reaches the longest minute level can be provided for vehicle drivers; and a traffic sign facility is used for transmitting the traffic sign information to a receiver on a vehicle through radio wave and transmitting to drivers, and preferably, the receiver transmits an active alarm signal corresponding to the received traffic sign information with the appointed type.

Description

technical field [0001] The invention relates to the field of traffic safety, in particular to a traffic early warning method, a transmitter, a receiver and a traffic early warning system. Background technique [0002] Road transportation plays an extremely important role in the operation of the national economy, and it is also an important choice for people to travel. With the increase in the number of vehicles, transportation has become increasingly crowded and busy, and various road traffic accidents have occurred frequently. , in order to avoid the occurrence of traffic accidents to the greatest extent, making full use of various road traffic status information to carry out effective traffic safety early warning has become an urgent subject before us. [0003] In road traffic activities, various road traffic condition information is very important to the driver's safe driving. For the driver, the road traffic condition information is the early warning information with tra...

Problems solved by technology

[0004] The traffic safety early warning behavior of the above-mentioned drivers naturally exists in their driving behavior and is an important link to ensure safe driving. However, this early warning behavior has obvious and insurmountable limitations: 1. The early warning information dissemination method is primitive and requires drivers to rely on It is directly observed by the naked eye, so the early warning information has a short transmission distance and is inevitably affected by factors such as visual distance, viewing angle, obstacles, driving speed, illumination, visibility, driver's mental state, glare of the sun or strong light when passing cars. Serious impact, resulting in the early warning effect is not always reliable, and the early warning time obtained is short, the early warning distance is short, and it is impossible to make early warnings for traffic conditions outside the visible area; 2. Lack of coordination mechanism for system engineering, and optimization cannot be obtained The early warning effect, the early warning information has no initiative, can only passively wait for the driver to perceive through the human sensory organs, there is no more effective information transmission channel between the subject that generates the early warning information and the driver of the vehicle, and the driver cannot report any accidents in the vehicle. In the event of an accident or abnormal situation, it actively sends out early warning information to other vehicles outside the visible area or receives early warning information from other traffic participants outside the visible area during normal driving, which greatly reduces the effect of early warning

These limitations of driver's early warning behavior often lead to frequent chain accidents, resulting in a large number of casualties and property losses, and also lead to road traffic blocking
