Embodiment
With reference to the accompanying drawings the embodiment of traffic information transferring method according to the present invention is described.In the process, the thickness of the lines shown in accompanying drawing or the size etc. of structural detail, in order to the definition that illustrates and convenient and may enlarged icon.Further, term described later considers technical ability in the present invention and the term defined, and they can be different according to the intention of user, operator or convention.Therefore, the definition for this term should be determined based on the content of this specification.
Fig. 3 is the schematic diagram in order to illustrate according to traffic information transferring method of the present invention, and Fig. 4 is to illustrate, for the schematic diagram of the frequency division multiple access that transport information of the present invention transmits.
As shown in Figure 3, suppose to there occurs accident to be described in a certain road.When a certain road generation traffic hazard, this accident relevant information sends to and is positioned at (such as: within the specific region of place where the accident occurred) vehicle near place where the accident occurred by traffic room.
Now, by accident relevant information (such as: position occurs accident, outside route) (first information) be equipped on the vehicle that the first frequency range (frequency range I) travels to A direction, place where the accident occurred (first direction) and transmit, and the general transport information (second information) irrelevant with accident is equipped on the vehicle that the second frequency range (frequency range II) travels to the direction (second direction) irrelevant with place where the accident occurred and transmits.
If, need transmit information category many time, as shown in Figure 4, can be equipped on be equivalent to Segmentation Number frequency range (such as: the 3rd frequency range, the 4th frequency range ..., N frequency range) transmit.
Fig. 5 is the process flow diagram in order to illustrate according to traffic information transferring method of the present invention, and with reference to Fig. 5, to the travel direction according to each vehicle, the method for being carried out emergence message transmission by the frequency range of distributing is described.
As shown in Figure 5, transport information conveyer (not shown) carries out frequency allocation (S101) according to the travel direction (or track) of each vehicle.Because the forward direction of vehicle can be determined according to track, therefore can be distinguished the travel direction of driving vehicle by specific track (such as: right-hand lane, left-hand lane).
Traffic information apparatus, according to each frequency range of segmentation, transmits and comprises the transport information (basic transport information) set.Therefore, the vehicle travelled to each track (or travel direction) can receive the basic transport information (S102) relevant to its travel direction.
As mentioned above, in the delivering letters of basic transport information (or in collecting mail), when there is traffic hazard (S104 is), transport information conveyer can be converted to emergency traffic communicating information pattern (S105).The pattern of emergency traffic information passed on by the vehicle of the terrain that emergency traffic communicating information pattern only occurs to described traffic hazard.
Transport information conveyer, in order to pass on emergency traffic information, can judge whether to be necessary to distribute (S106) frequency again.That is, when being only assigned with the frequency in order to transmit basic transport information, in order to transmit emergency traffic information, need to carry out additional parallel compensate.
If when needing to carry out additional parallel compensate (S106 is), transport information conveyer can transmit emergency traffic information (or emergency information) (S108) by the frequency range of additional parallel compensate.
In contrast, when not needing to carry out additional parallel compensate (S106's is no), transport information conveyer can use the frequency range of existing distribution preferentially to transmit emergency traffic information (or emergency information) (S107).
As mentioned above, after transmitting emergency traffic information, transport information conveyer can judge whether also to need emergency traffic information (emergency information) (S109).
Now, whether transport information conveyer can be complete thus terminate situation according to the accident treatment of place where the accident occurred, or according to the vehicle whether had to place where the accident occurred direction running, can judge whether also to need emergency traffic information.
If when also needing emergency traffic information (S109 is), transport information conveyer can continue to maintain emergency traffic communicating information pattern (S105 ~ S109).
But when not needing emergency traffic information (S109's is no), transport information conveyer can judge vehicle (S110) whether out of service.
If when vehicle does not have out of service (S110's is no), can judge whether to maintain the frequency range (S103) of distributing now.
When not maintaining frequency range (S103's is no), with first step (S101), new frequency range is distributed according to the travel direction of each driving vehicle, when maintaining existing frequency range (S103 is), transmit basic transport information (S102) according to each frequency range of existing distribution.
Describe the present invention with reference to the embodiment shown in accompanying drawing above, but this is only exemplary embodiment, general technical staff of the technical field of the invention should be appreciated that and therefrom can realize various deformation and other equivalent embodiments.
