Embodiment

Existing with detailed reference example embodiment of the present invention, the instance of said example embodiment will be described in the accompanying drawings.In addition, all possibility parts use element/member of same numeral to represent identical or similar portions in accompanying drawing and embodiment.

Fig. 1 shows the calcspar of the E-payment system (electronic toll collection system, ETC system) 100 of the present invention's one example embodiment, and Fig. 2 shows the synoptic diagram that the E-payment system 100 of Fig. 1 is implemented in turn pike.Please merge with reference to Fig. 1 and Fig. 2; Control module (central control module) 101, charge module (toll collection module) 103, identification module (identification module) 105 during E-payment system 100 comprises, and law enforcement module (law enforcement module) 107.Basically, middle control module 101 is in order to the behavior of leading (guide) charge module 103, identification module 105 and law enforcement module 107.That is to say that the running (operation) of charge module 103, identification module 105 and law enforcement module 107 is all controlled/controlled by middle control module 101.Hence one can see that, and middle control module 101 can be a powerful servo-drive system (server system) or workstation (workstation), but neitherly be limited to this.

Control module 101 during charge module 103 is controlled by and (for example can send service of withholing in advance and the service of withholing afterwards relatively on a large scale in one with the service of withholing afterwards (post-pay service) through one group of high-power omni-directional antenna (omni antenna) in order to issue the service of withholing in advance (pre-pay service); But be not restricted to this); Use and make and to go at turn pike (highway for example; But be not restricted to this) on the car machine (OBU is installed in the vehicle 201) of vehicle 201 react on this service of withholing in advance and the service of afterwards withholing one of them and accomplish and withhold.

Identification module 105 be controlled by in the control module 101 and in order to the acquisition (capture) vehicle 201 image (image); And the car machine (OBU) that is installed in the vehicle 201 (for example can send the identification service relatively among a small circle in through one of them or combination of many group miniwatt oriented antennas (directional antenna)) is given in issue identification service (identification service), uses the status information (identification information) of car plate (license plate) that acquisition includes vehicle 201 at least and model (model).Wherein, the communication context that each group miniwatt oriented antenna is covered is approximately the width in a track, but is not restricted to this.

Control module 101 during law enforcement module 107 is controlled by and in order to receive and to link the image and status information (when identification module 107 has the status information of acquisition vehicle 201) of (link) vehicle 201; Thereby write down (that is the data storing of image that links vehicle 201 and status information in database (database)); Otherwise; Only the image of reception and registration of vehicle 201 is not (when identification module 107 obtains the status information of vehicle 201; Possible vehicle 201 is not installed car machine (OBU), and the car machine (OBU) that perhaps is installed in the vehicle 201 breaks down), use the foundation of enforcing the law as backward.

In this example embodiment, charge module 103 can be given the car machine (OBU) in the vehicle 201 that is installed in the service of withholing afterwards in first communication context (that is the communication context of withholing in advance of Fig. 2 (pre-pay communication range) E and communication context (the post-pay communication range) F that withholds contain scope) the issue service of withholing in advance afterwards; In addition; Identification module 105 can be in the image of second communication context (that is the identification communication context of Fig. 2 (identification communication range) A～D contain scope) acquisition vehicle 201, and the car machine (OBU) that is installed in the vehicle 201 is given in issue identification service.

In other words, first communication context can comprise withhold in advance the communication context E and the communication context F that afterwards withholds; And second communication context can comprise a plurality of identification communication context A～D, and a plurality of tracks (lane) L1～L4 of identification communication context A～corresponding equivalent of D (isometric).Hence one can see that, and the communication context E that withholds in advance can be contained all identification communication context A～D.That is to say that the subregion of the communication context E that withholds in advance can overlap (overlap) together with identification communication context A～D.

Based on above-mentioned; When vehicle 201 for example goes on the L2 of the track of turn pike; And got into when withholing communication context E in advance; Control module 101 can be based on particular communication agreement (specific communication protocol then; IEEE 1609 communications protocols for example; But be not restricted to this) and the car machine (OBU) that is installed in the vehicle 201 is given in control channel (control channel, that is passage 178) the issue service of withholing in advance that control charge module 103 is provided in IEEE 1609 communications protocols, use to make the car machines (OBU) in the vehicle 201 of being installed in can react on this service of withholing in advance and service channel (the pay service channel that withholds in a plurality of (that is the 6) service channels (service channel) that IEEE 1609 communications protocols are provided; For example passage 182, but are not restricted to this) carry out one " intermittently (intermittent) withhold program ".

In this; Because the control channel (passage 178) that IEEE 1609 communications protocols are provided and the frequency (frequency) different each other (as shown in Figure 3) of 6 service channels (passage 172,174,176,180,182,184); And IEEE 1609 communications protocols can provide alternate channel access mode (alternating channel access mode) (as shown in Figure 4); So in case the car machines (OBU) that are installed in the vehicle 201 listen to charge module 103 after the service of withholing in advance of being issued on the control channel (passage 178) that IEEE 1609 communications protocols are provided, pay in the service channel of withholing (passage 182) that the car machines (OBU) in the vehicle 201 of being installed in will arrive IEEE 1609 communications protocols to be provided.

In present embodiment; Because the service period (service interval) of the service channel of withholing (passage 182) that IEEE 1609 communications protocols are provided is limited; So the car machine (OBU) that is installed in the vehicle 201 possibly just might be accomplished withhold (that is also might can't accomplish and withhold) after alternate channel access is repeatedly carried out in service channel (passage 182) with withholing in control channel (passage 178) that IEEE 1609 communications protocols are provided, and the connotation of this just aforementioned " program of intermittently withholing " belongs to.Yet; Can accomplish after the car machine (OBU) in the vehicle 201 of being installed in also might only carry out alternate channel access once in the control channel (passage 178) that IEEE 1609 communications protocols are provided and the service channel (passage 182) of withholing and withhold, all are all looked the communication network environment and decide.

In this example embodiment, when the car machine (OBU) in being installed in vehicle 201 was withholdd program success (succeed) the intermittence that the communication context E that withholds is in advance carried out, then expression was accomplished and is withholdd; Otherwise when the car machine (OBU) in being installed in vehicle 201 was withholdd procedure failure (fail) the intermittence that the communication context E that withholds is in advance carried out, then expression was accomplished and is withholdd.In this, the car machines (OBU) in the vehicle 201 of being installed in have the ability necessarily to know that the program of withholing at intermittence of being carried out in the communication context E that withholds in advance be successfully or fails.

And then; When go on the L2 of the track of turn pike vehicle 201 through set up in advance (mount) on turn pike a plurality of arrangements in line with across moment of induction installation (sensor) S of track L1～L4 (circle stain straight line place of beating as shown in Figure 2; It can be considered the part of identification module 105; And the mechanism that can realize sense vehicle 201) by one of them or combination of technology such as microwave, optics and pressure; Identification module 105 can be by control module 101 in the induction installation S notice, and vehicle 201 can enter to identification communication context B (suppose vehicle 201 is kept go on the L2 of track).Yet if vehicle 201 is converted into track L3 before getting into identification communication context B temporarily, identification module 105 can be by control module 101 in the induction installation S notice, and vehicle 201 can enter to identification communication context C.

Thus; In control module 101 will control identification module 105 immediately (trigger) any device G that can make a video recording (be vehicle 201 keep go on the L2 of track)/(it all can be considered the part of identification module 105 to G ' (being that vehicle 201 is converted on the L3 of track) to trigger; And can be camera, CCD CIS, CMOS CIS etc.; But neitherly be limited to this; And the two device G that make a video recording and the image pickup scope of G ' can capture the image that three vehicles are parallel to two tracks) capture the image of vehicle 201; And control channel (passage 178) the issue identification service that control module 201 also can be controlled identification module 105 based on IEEE 1609 communications protocols and provided in IEEE 1609 communications protocols in this moment is installed in the car machine (OBU) vehicle 201 in, use make the car machines (OBU) in the vehicle 201 of being installed in react on this identification service and the status information of one of them (for example passage 176) repayment vehicle 201 of a plurality of identifications service channel (except passage 182) in 6 service channels (passage 172,174,176,180,182,184) that IEEE 1609 communications protocols are provided (that is the car plate of vehicle 201, model etc.) to identification module 105.

On the other hand; Even if vehicle 201 is converted into the identification communication context C of track L3 again behind the identification communication context B that gets into track L2 temporarily; Because identification module 105 is installed in the car machine (OBU) in the vehicle 201 in identification communication context B issue identification service, the car machine (OBU) that is installed in the vehicle 201 still can react on this identification service and give identification module 105 in the status information of identification service channel (that is passage 176) the repayment vehicle 201 that IEEE 1609 communications protocols are provided.In other words, vehicle 201 changing Lane how no matter, the car machines (OBU) in the vehicle 201 of being installed in all can be repaid the status information of vehicle 201 in identification module 105 specified identification service channels.

In this exemplary enforcement; Keep when vehicle 201 and to go on the L2 of track; And when having entered to the overlapping zone (that is shown in Figure 2 beat hatched example areas) of withhold in advance communication context E and identification communication context B, the service of withholing in advance that the control channel (passage 178) that the right of priority (priority) of control channel (passage 178) the issue identification service that middle control module 101 leading identification modules 105 are provided in IEEE 1609 communications protocols can be higher than the module 103 of charging to be provided in IEEE 1609 communications protocols is issued.Can seem, middle control module 101 has the ability (scheduling) dispatched in service of withholing in advance and identification service.

In addition; Because IEEE 1609 communications protocols can provide passage access mode (immediate channel access mode) (as shown in Figure 4) immediately; (that is shown in Figure 2 beat hatched example areas) receives identification that identification module 105 issued when serving so in case the car machine (OBU) in the vehicle 201 of being installed in is in this zone that overlaps; The car machine (OBU) in the vehicle 201 of being installed in will immediate response be repaid the status information of vehicle 201 constantly and is given identification module 105 in this identification service and in the identification service channel of correspondence (that is passage 176), till a Preset Time (by its time length of actual state decision).That is the car machine (OBU) that is installed in the vehicle 201 is the service that the control channel (passage 178) that can not monitor IEEE 1609 communications protocols and provided is issued at this section Preset Time.In other words, in case surpass this section Preset Time, the service that the control channel (passage 178) that the car machines (OBU) in the vehicle 201 of being installed in just can recover to monitor the IEEE1609 communications protocol and provided is issued.

What deserves to be mentioned is earlier that at this different car machine (OBU) that is positioned at adjacent lane reacts on the status information of same identification service meeting its vehicle out of the ordinary of repayment in different identification service channel that identification module 105 issued and gives identification module 105.For instance, the car machine (OBU) of in the track three cars of L1～L3 can distinctly repay its vehicle out of the ordinary in 3 different identification service channels (for example passage 174,176,180) that IEEE 1609 communications protocols are provided the status information of going is given identification module 105.In other words, repayment its each other status information in identification service channel that the vehicle on the adjacent lane can be different is given identification module 105, thereby is able to avoid repay the passage competitive behavior of the status information of vehicle.

Therefore; When identification module 105 captures the image of vehicle 201, and when also obtaining the status information of vehicle 201, middle control module 101 will further be controlled the image and status information (that is the image of vehicle 201 has one corresponding (mapping) to concern with the status both information) that law enforcement module 107 received and linked vehicle 201; Thereby carry out record; Otherwise control law enforcement module 107 only receives the also image of registration of vehicle 201, uses the foundation of enforcing the law as backward.

Subsequently; When vehicle 201 enters to when withholing communication context F from identification communication context B afterwards; If having accomplished in the communication context E that withholds in advance, the car machine (OBU) in the vehicle 201 of being installed in withholds the service of afterwards withholing that the car machine (OBU) in the vehicle 201 that then is installed in is controlled charge module 103 and provided in IEEE 1609 communications protocols with regard to control module 101 in no longer monitoring/comprehending based on the IEEE1609 communications protocol control channel (passage 178) is issued.

Yet; If accomplishing in the communication context E that withholds in advance, the car machine (OBU) in the vehicle 201 of being installed in do not withhold the service of afterwards withholing that the control channel (passage 178) that control module 101 was controlled charge module 103 and provided in IEEE 1609 communications protocols during the car machines (OBU) in the vehicle 201 of then being installed in will be monitored/comprehend based on IEEE 1609 communications protocols is issued.Thus, the car machines (OBU) in the vehicle 201 of being installed in will react on this service of afterwards withholing and carry out one in the service channel of withholing (passage 182) that IEEE 1609 communications protocols are provided " continuity (extended) withhold program ", withhold thereby accomplish.Certainly; In other example embodiment of the present invention; The car machines (OBU) in the vehicle 201 of being installed in also can react on the service of afterwards withholing and (that is be different from another passage of the passage 182) carries out " continuity withhold program " in another service channel of withholing that IEEE 1609 communications protocols are provided, and withhold thereby accomplish.All are looked closely actual design demand/situation and discuss.

In this; Because IEEE 1609 communications protocols can provide continuity passage access mode (extendedchannel access mode) (as shown in Figure 4); So in case the car machines (OBU) that are installed in the vehicle 201 listen to charge module 103 after the service of withholing of being issued on the control channel (passage 178) that IEEE 1609 communications protocols are provided afterwards, the car machines (OBU) in the vehicle 201 of being installed in will arrive the service channel of withholing that IEEE 1609 communications protocols are provided (passage 182 or be different from another passage of passage 182) and pay.

And; The service period (service interval) of (passage 182 or be different from another passage of passage 182) is length (not needing to monitor any service of being issued on the control channel (passage 178) that IEEE 1609 communications protocols are provided because of the car machine (OBU) in the vehicle 201 of being installed in) down relatively at continuity passage access mode again because the service channel of withholing that provided of IEEE 1609 communications protocols; So the car machine (OBU) in the vehicle 201 of being installed in can be in the service channel of withholing that IEEE 1609 communications protocols are provided (passage 182 or be different from another passage of passage 182) pay (that is car machine (OBU) more time that is installed in vehicle 201 in is withholdd with completion) with endeavouring, and the connotation that this is just aforementioned " continuity withhold program " belongs to.But, still can't withhold as if the car machines (OBU) that are installed in the vehicle 201 in the communication context F completion of withholing afterwards, then law enforcement agency just must adopt the next foundation as the law enforcement voucher of the image that is recorded in vehicles 201 in the law enforcement module 107.

Content based on above-mentioned example embodiment disclosed can be known; E-payment system 100 can be carried out communication with the car machine (OBU) that is installed in the vehicle 201 down a big relatively communication context (the communication context E and the communication context F that withholds in advance withhold) afterwards, thereby the feasible car machines (OBU) that are installed in the vehicle 201 are paid (withholing); In addition, E-payment system 100 can be at a relatively little communication context (identification communication context A～D) carry out communication with the car machine (OBU) that is installed in the vehicle 201 down, thereby the image of acquisition vehicle 201 and the status information that obtains vehicle 201.

Thus; E-payment system 100 can realize that not only the target of the free wagon flow electronic charging of multilane (multi-lane free flow ETC) is not (because vehicle needs on fixing track (conversion traveling lane arbitrarily); Nor need painstakingly to slow down); And can accurately the image and the status information of vehicle be done an effectively binding again, thereby promote the efficient and the public credibility (to travelling on the vehicle of paying the fees on the turn pike) of law enforcement aspect.In addition, because E-payment system 100 only realizes the charge and the law enforcement of the free wagon flow of multilane with single open international standard communications protocol (that is IEEE 1609 communications protocols).Therefore, will help to promote the development that various countries are associated with the industry of turn pike.

What deserves to be mentioned is in this; Though above-mentioned example embodiment is to carry out communication with the car machine (OBU) that is installed in the vehicle 201 through IEEE 1609 communications protocols with E-payment system 100; But in other example embodiment; E-payment system 100 also can adopt other network conventions with hyperchannel (multi-channel) to carry out communication with the car machine (OBU) that is installed in the vehicle 201, and the embodiment of these distortion also belongs to one of category of institute of the present invention desire protection.

On the other hand, can know that the operation workflow of car machine (OBU) after configuration (configured) that is installed in the vehicle 201 can be as shown in Figure 5 based on the content that above-mentioned example embodiment disclosed.In other words, the car machine (OBU) that is installed in the vehicle 201 can be carried out following flow process after configuration:

Judge whether to obtain the service of withholing in advance (S501) in the communication context of withholing in advance;

As obtaining in the communication context of withholing in advance when withholing service in advance, then carry out the program of withholing intermittence, and judged whether to obtain identification simultaneously and serve (S503);

As obtaining when service identification, then repay status information to one Preset Time of vehicle immediately and constantly till (by its time length of actual state decision) (S505), otherwise, continue to carry out the program of withholing intermittence till leave the communication context of withholing in advance;

After the status information number of repayment vehicle, judge intermittently whether the program of withholing has success (S507);

When intermittently withholing the program success, then expression is accomplished and is withholdd (S509), otherwise, judge whether to obtain the service of afterwards withholing (S511) in the communication context of withholing afterwards; And

As obtain when service of withholing in the communication context of withholing afterwards afterwards, then continue the program of withholing (S513), use to accomplish and withhold, otherwise, continue to have judged whether to obtain the service of afterwards withholing till leave the communication context of afterwards withholing.

Hence one can see that, and the car machines (OBU) in the vehicle 201 of being installed in react on the identification service and the right of priority of the status information of repayment vehicle can be higher than it and reacts on the program of the service of withholing in advance carried out intermittently withholing.In simple terms, the status information that is installed in car machines (OBU) the repayment vehicle 201 in the vehicle 201 can have precedence over paying.Thus, even if the car machines (OBU) in the vehicle 201 of being installed in are accomplished do not withhold, law enforcement agency also can be by the status of the vehicle that is obtained 201 to report.

On the other hand, also can know that the identification module 105 of E-payment system 100 can be as shown in Figure 6 with the operation workflow of law enforcement module 107 after configuration (configured) based on the content that above-mentioned example embodiment disclosed.In other words, the identification module 105 of E-payment system 100 can be carried out following flow process with law enforcement module 107 after configuration:

Whether sense vehicle has the identification of entering communication context (S601);

Got into when discerning communication context in case sense vehicle, captured the image of vehicle through the device that can make a video recording, and begin to carry out time counting (S603), whether the identification of entering communication context has been arranged otherwise continue sense vehicle;

Same time/next-door neighbour's time, see the identification service off and give the car machine (OBU) that is installed in the vehicle (S605), and judge whether the time of being counted surpasses a Preset Time (S607);

If be not more than the described Preset Time of step S607, judge then whether the car machine (OBU) that is installed in the vehicle has the status information (S609) of repayment vehicle, otherwise the image (S611) of the vehicle that transmission is captured is used and is write down (S613); And

If be installed in the words that the interior car machine (OBU) of vehicle is not repaid the status information of vehicle; Then repeat to see off the identification service and give the car machine (OBU) that is installed in the vehicle; Till surpassing Preset Time; Otherwise the image and the status information (S615) of the vehicle that transmission and binding are captured are used and are write down (S613).

The advantage of the E-payment system 100 that in sum, above-mentioned example embodiment disclosed have at least following some:

1, the service of distinctly issuing of charge module and identification module institute can be through dispatching (scheduling) to guarantee that machine/time is obtained suitable service to vehicle in due course;

2, the car machine (OBU) in the different vehicle can react on identical identification service and repay the status information of its vehicle out of the ordinary through different service channels; So on the communication basis, can't bump; Can promote the success ratio of service by this; And can solve the problem of any changing Lane of vehicle simultaneously again, thereby meet the notion of the free wagon flow of multilane;

3, realize the charge and the law enforcement of the free wagon flow of multilane (MLFF) with single open international standard communications protocol (that is IEEE 1609 communications protocols).Therefore, will help to promote the development that various countries are associated with the industry of turn pike;

4, identification module can carry out communication in the car machine (OBU) in different service channels and vehicle are adopted in each track, and the car machine (OBU) in the vehicle also can adopt the communication modes of omni-directional antenna, does not need the communication modes of certain architectures at oriented antenna; And

5, charge module and identification module can Collaboration, uses the success ratio of lifting E-payment system, and more can use the characteristic of microwave Wide Area Communication effectively.

Though the present invention discloses as above with embodiment; Right its is not in order to limit the present invention; Those skilled in the art can do some changes and retouching under the premise without departing from the spirit and scope of the present invention, so protection scope of the present invention is as the criterion with claim of the present invention.
