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...

Examples

Embodiment 1

[0047] A traffic warning method, comprising:

[0048] A. The information sender determines and triggers the traffic warning information corresponding to the traffic condition information according to the input traffic condition information, and the traffic warning information is triggered automatically, manually or according to a time cycle cycle;

[0049] B. The information sender encodes the traffic early warning information according to a preset method to obtain a traffic early warning baseband signal, and uses the traffic early warning baseband signal to modulate a carrier to obtain a modulated traffic early warning signal;

[0050] C. The information sender uses a broadcast communication method to transmit the modulated traffic warning signal through the transmitting antenna in the form of radio waves in a directional or omnidirectional manner;

[0051] D. The information receiver receives the modulated traffic warning signal transmitted in the form of radio waves from a ...

Embodiment 2

[0075] A traffic warning method, comprising the steps of:

[0076] Step 101, the information sender determines and triggers the traffic warning information according to the traffic condition information;

[0077] Traffic status information is the abstracted information related to road traffic conditions, vehicle conditions, traffic facilities, driving conditions, etc., such as: traffic accidents, vehicle failures, road congestion, traffic sign information, bad weather, etc.;

[0078]Traffic early warning information includes early warning information corresponding to various abstract traffic status information, such as: traffic sign information, traffic control command and guidance information, traffic abnormal information, vehicle speed information, traffic accident warning information, vehicle failure warning information, road parking Warning information, vehicle distance warning information, weather anomaly information, road anomaly information, vehicle anomaly information,...

Embodiment 3

[0114] Continuing the steps 101-107 in the embodiment 2, in order to give full play to the early-warning effect of the traffic early-warning information with direct and significant significance to driving safety more fully, and amplify the early-warning effect, the information receiver is responsible for carrying out after receiving this type of traffic early-warning information. The obligation of relay forwarding is to carry out multi-layer forwarding of the traffic warning information layer by layer in a hierarchical topology among multiple information receivers. With the relay forwarding layer by layer, such The traffic warning information is further disseminated to farther places, so that the information receiver who receives the forwarded information increases the warning distance, and then obtains a longer warning time, and the safety benefits brought by the traffic safety warning are more significant.

[0115]However, if the traffic early warning information is forwarded...
