Description

Multi-lane free traffic flow electronic toll collection system and its vehicle

technical field

The invention relates to an electronic toll collection system, in particular to an electronic toll collection (ETC) system and its on board unit (OBU) for multi-lane free traffic flow.

Background technique

At present, most of the road toll collection operations for vehicles on expressways in the world adopt the method that vehicles stop at toll booths and are allowed to pass after paying by manual payment. At the station, you must first stop and pay the toll before driving, which virtually increases the waste of time for passers-by and increases air pollution.

In addition, there are also a few who use the erection lane system to conduct transactions in a specific short-range communication protocol (dedicated short range communication, DSRC), or use the global positioning system (global positioning system, GPS) combined with mobile communication methods (such as general packet radio service , GPRS) electronic toll collection (ETC) system, so as to realize the purpose of automatic operation of electronic toll collection.

However, no matter which of the above-mentioned electronic toll collection system architectures (that is, DSRC or GPS+GPRS), it is difficult to achieve the purpose of multi-lane free flow ETC, because driving in multi-lane free flow Vehicles under the traffic flow do not need to be in a fixed lane, and do not need to deliberately slow down, which causes difficulties in charging and law enforcement.

Contents of the invention

In view of this, the present invention provides an electronic toll collection system, which includes: a charging module for issuing a pre-deduction service and a post-deduction service, so that a vehicle machine on a vehicle can respond to the pre-deduction service service and the post-deduction service to complete deduction; and an identification module, used to capture the image of the vehicle, and issue an identification service to the vehicle, so as to obtain the identity information of the vehicle.

The present invention also provides a car machine installed in a vehicle, and configured to: determine whether to obtain a pre-deduction service in a pre-deduction communication range; When the deduction service is performed, an intermittent deduction procedure is performed, and at the same time, it is judged whether an identification service has been obtained; Carry out the intermittent deduction procedure until leaving the pre-deduction communication range; after reporting the vehicle’s identity information number, judge whether the intermittent deduction procedure is successful; when the intermittent deduction procedure is successful, it means that the deduction is completed, Otherwise, judge whether to obtain a post-deduction service in a post-deduction communication range; and when the post-deduction service is obtained in the post-deduction communication range, perform a continuation deduction procedure to complete the deduction, otherwise , continue to judge whether the post-deduction service has been obtained until leaving the post-deduction communication range.

Detailed ways

Reference will now be made in detail to the exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. In addition, wherever possible, elements/components using the same reference numerals in the drawings and embodiments represent the same or similar parts.

FIG. 1 shows a block diagram of an electronic toll collection system (electronic toll collection system, ETC system) 100 according to an exemplary embodiment of the present invention, and FIG. 2 shows a schematic diagram of implementing the electronic toll collection system 100 of FIG. 1 on a toll road. Please refer to FIG. 1 and FIG. 2 together. The electronic toll collection system 100 includes a central control module 101, a toll collection module 103, an identification module 105, and a lawenforcement module 107. Basically, the central control module 101 is used to guide the actions of the charging module 103 , the identification module 105 and the law enforcement module 107 . That is to say, the operations of the billing module 103 , the identification module 105 and the law enforcement module 107 are all controlled/controlled by the central control module 101 . It can be seen that the central control module 101 can be a powerful server system or a workstation, but it is not limited thereto.

The charging module 103 is controlled by the central control module 101 and is used to issue pre-pay service and post-pay service (for example, through a group of high-power omnidirectional antennas (omni antenna) And send pre-deduction services and post-deduction services in a relatively large range, but not limited to this), so that the vehicle 201 of the vehicle driving on a toll road (such as a highway, but not limited to this) (OBU, installed in the vehicle 201) responds to one of the pre-deduction service and the subsequent deduction service to complete the deduction.

The identification module 105 is controlled by the central control module 101 to capture (capture) the image (image) of the vehicle 201, and issue identification service (identification service) to the vehicle unit (OBU) installed in the vehicle 201 (for example, can Send identification service in a relatively small range through one or a combination of multiple groups of low-power directional antennas (directional antenna), so as to obtain at least the identity information including the license plate and model of the vehicle 201 (identification information). Wherein, the communication range covered by each group of low-power directional antennas is about the width of a lane, but it is not limited thereto.

The law enforcement module 107 is controlled by the central control module 101 and is used to receive and link (link) the image and identity information of the vehicle 201 (when the identification module 107 has obtained the identity information of the vehicle 201), thereby recording (that is, the linked The image and identity information of the vehicle 201 are stored in the database), otherwise, only the image of the vehicle 201 is received and recorded (when the identification module 107 does not obtain the identity information of the vehicle 201, it is possible that the vehicle 201 is not equipped with machine (OBU), or the vehicle machine (OBU) installed in the vehicle 201 has broken down), so as to serve as the basis for future law enforcement.

In this exemplary embodiment, the charging module 103 can be used in the first communication range (that is, the pre-pay communication range (pre-pay communication range) E and the post-pay communication range (post-pay communication range) F in FIG. 2 ) Scope covered) to issue pre-deduction services and post-deduction services to the vehicle unit (OBU) installed in the vehicle 201; in addition, the identification module 105 can be in the second communication range (that is, the identification communication range of FIG. 2 ( The identification communication range) A~D) captures the image of the vehicle 201, and issues the identification service to the on-board unit (OBU) installed in the vehicle 201.

In other words, the first communication range may include the pre-deduction communication range E and the post-deduction communication range F; and the second communication range may include multiple identification communication ranges A~D, and the identification communication ranges A~D correspond to equivalent (isometric ) of multiple lanes (lanes) L1-L4. It can be seen from this that the pre-deduction communication range E can cover all identification communication ranges A-D. That is to say, some areas of the pre-debit communication range E overlap with the identification communication ranges A˜D.

Based on the above, for example, when the vehicle 201 is driving on the lane L2 of the toll road and has entered the communication range E of the deduction in advance, the central control module 101 will be based on a specific communication protocol (specific communication protocol, such as the IEEE 1609 communication protocol, but not not limited thereto) and the control charging module 103 issues the deduction service in advance to the vehicle unit (OBU) installed in the vehicle 201 on the control channel (control channel, namely channel 178) provided by the IEEE 1609 communication protocol, so as to make The on-board unit (OBU) installed in the vehicle 201 can respond to the deduction service in advance and provide a deduction service channel among multiple (that is, 6) service channels (service channels) provided by the IEEE 1609 communication protocol (pay service channel, such as channel 182, but not limited thereto) carry out an "intermittent (intermittent) deduction procedure".

Here, since the frequencies (frequency) of the control channel (channel 178) and the six service channels (channels 172, 174, 176, 180, 182, 184) provided by the IEEE 1609 communication protocol are different from each other (as shown in FIG. 3 ), and the IEEE 1609 communication protocol can provide an alternate channel access mode (alternating channel access mode) (as shown in Figure 4), so once the vehicle unit (OBU) installed in the vehicle 201 monitors the charging module 103 in IEEE 1609 After the pre-deduction service issued on the control channel (channel 178) provided by the communication agreement, the vehicle unit (OBU) installed in the vehicle 201 will go to the deduction service channel (channel 182) provided by the IEEE 1609 communication agreement. ) to make a payment.

In this embodiment, since the service interval (service interval) of the chargeback service channel (channel 182) provided by the IEEE 1609 communication protocol is limited, the vehicle unit (OBU) installed in the vehicle 201 may need to communicate with IEEE 1609 The control channel (channel 178) and the deduction service channel (channel 182) provided by the agreement can only complete the deduction after multiple alternate channel accesses (that is, the deduction may not be completed), and this is the aforementioned What is meant by the "intermittent debit procedure". However, the on-board unit (OBU) installed in the vehicle 201 may also perform only one alternate channel access to the control channel (channel 178) and the deduction service channel (channel 182) provided by the IEEE 1609 communication protocol. To complete the deduction, everything depends on the communication network environment.

In this exemplary embodiment, when the intermittent deduction procedure carried out by the OBU installed in the vehicle 201 in the pre-deduction communication range E is successful (succeed), it means that the deduction is completed; otherwise, when When the intermittent deduction procedure performed by the on-board unit (OBU) installed in the vehicle 201 in the pre-deduction communication range E fails (fail), it means that the deduction has not been completed. Here, the on-board unit (OBU) installed in the vehicle 201 must be able to know whether the intermittent deduction procedure performed in the pre-deduction communication range E is successful or failed.

Immediately afterwards, when the vehicle 201 driving on the lane L2 of the toll road passes through a plurality of induction devices (sensor) S that are arranged in a straight line on the toll road in advance to cross the lanes L1-L4 (as shown in Figure 2 The circled black dot shown in the straight line can be regarded as a part of the recognition module 105, and the mechanism of sensing the vehicle 201 can be realized by one or a combination of technologies such as microwave, optics and pressure), the recognition module 105 will The central control module 101 is notified by the sensing device S that the vehicle 201 will enter the identification communication range B (assuming that the vehicle 201 keeps driving on the lane L2). However, if the vehicle 201 temporarily changes to the lane L3 before entering the identification communication range B, the identification module 105 will notify the central control module 101 through the sensing device S, and the vehicle 201 will enter the identification communication range C.

In this way, the central control module 101 will immediately control the identification module 105 to trigger (trigger) any device that can take pictures G (that is, the vehicle 201 keeps driving on the lane L2)/G' (that is, the vehicle 201 changes to the lane L2 On L3) (it can be regarded as a part of the identification module 105, and can be a camera, a CCD image sensor, a CMOS image sensor, etc., but is not limited thereto, and the two imaging devices G and G' The camera range can capture images of three vehicles running parallel in two lanes) to capture the image of the vehicle 201, and at this time the central control module 201 will also control the identification module 105 based on the IEEE 1609 communication protocol provided by the IEEE 1609 communication protocol The control channel (channel 178) issues the identification service to the on-board unit (OBU) installed in the vehicle 201, so that the on-board unit (OBU) installed in the vehicle 201 responds to the identification service and conforms to the IEEE 1609 communication protocol. One of the multiple identification service channels (except channel 182) among the provided 6 service channels (channels 172, 174, 176, 180, 182, 184) (for example channel 176) returns the identity information of the vehicle 201 (also That is, the license plate, model, etc. of the vehicle 201) to the identification module 105.

On the other hand, even if the vehicle 201 temporarily changes to the identification communication range C of the lane L3 after entering the identification communication range B of the lane L2, since the identification module 105 has issued the identification service to the identification communication range B installed in the vehicle 201 On-board unit (OBU), so the on-board unit (OBU) installed in the vehicle 201 will still respond to this identification service and report the identity information of the vehicle 201 on the identification service channel (that is, channel 176) provided by the IEEE 1609 communication protocol to the identification module 105. In other words, no matter how the vehicle 201 changes lanes, the vehicle unit (OBU) installed in the vehicle 201 will report the identity information of the vehicle 201 in the identification service channel designated by the identification module 105 .

In this exemplary implementation, when the vehicle 201 keeps driving on the lane L2 and has entered the overlapping area of the pre-deduction communication range E and the identification communication range B (that is, the hatched area shown in FIG. 2 ) The control channel (channel 178) provided by the control channel (channel 178) provided by the central control module 101 in the IEEE 1609 communication protocol will be higher than the control channel (channel 178) provided by the charging module 103 in the IEEE 1609 communication protocol. 178) Advance debit service posted. It can be seen that the central control module 101 is capable of scheduling the deduction service and identification service in advance.

In addition, since the IEEE 1609 communication protocol can provide an immediate channel access mode (immediate channel access mode) (as shown in FIG. 4 ), once the vehicle unit (OBU) installed in the vehicle 201 is in this overlapping area (that is, as shown in FIG. 2) when receiving the identification service issued by the identification module 105, the on-board unit (OBU) installed in the vehicle 201 will immediately respond to the identification service and in the corresponding identification service channel (also That is, the channel 176) continuously reports the identity information of the vehicle 201 to the identification module 105 until a preset time (the length of time is determined by the actual situation). That is, the on-board unit (OBU) installed in the vehicle 201 will not monitor the services issued by the control channel (channel 178 ) provided by the IEEE 1609 communication protocol during this preset time. In other words, once the preset period of time is exceeded, the on-board unit (OBU) installed in the vehicle 201 will resume listening to services issued by the control channel (channel 178 ) provided by the IEEE1609 communication protocol.

It is worth mentioning here that different OBUs located in adjacent lanes will report the identity information of their respective vehicles to the identification module in different identification service channels in response to the same identification service issued by the identification module 105 105. For example, the OBUs (OBUs) of the three vehicles driving in the lanes L1-L3 can report their respective identification service channels (such as channels 174, 176, and 180) provided by the IEEE 1609 communication protocol. The identity information of each vehicle is given to the recognition module 105 . In other words, vehicles on adjacent lanes can report their respective identity information to the identification module 105 through different identification service channels, thereby avoiding channel competition behavior of reporting the vehicle's identity information.

Therefore, when the identification module 105 captures the image of the vehicle 201 and also obtains the identity information of the vehicle 201, the central control module 101 will further control the law enforcement module 107 to receive and link the image of the vehicle 201 and the identity information (that is, the vehicle 201 There is a mapping relationship between the image of the vehicle 201 and the identity information), so as to record, otherwise, the control law enforcement module 107 only receives and records the image of the vehicle 201 as a basis for future law enforcement.

Subsequently, when the vehicle 201 enters from the identification communication range B to the post-deduction communication range F, if the on-board unit (OBU) installed in the vehicle 201 has completed the deduction in the pre-deduction communication range E, it will be installed in the The on-board unit (OBU) in the vehicle 201 no longer monitors/regards the post-deduction service issued by the central control module 101 based on the IEEE1609 communication protocol and controls the charging module 103 in the control channel (channel 178) provided by the IEEE1609 communication protocol.

However, if the on-board unit (OBU) installed in the vehicle 201 has not completed deduction within the pre-deduction communication range E, the on-board unit (OBU) installed in the vehicle 201 will monitor/disregard the central control module 101 Based on the IEEE 1609 communication protocol, the post-deduction service issued by the charging module 103 on the control channel (channel 178) provided by the IEEE 1609 communication protocol is controlled. In this way, the on-board unit (OBU) installed in the vehicle 201 will respond to the subsequent deduction service and carry out an "extended (extended) deduction in the deduction service channel (channel 182) provided by the IEEE 1609 communication protocol. Payment procedure" to complete the deduction. Of course, in other exemplary embodiments of the present invention, the on-board unit (OBU) installed in the vehicle 201 can also respond to the post-deduction service in another deduction service channel provided by the IEEE 1609 communication protocol (also That is, another channel (different from the channel 182) carries out the "continuation of the deduction procedure" to complete the deduction. Everything depends on the actual design needs/situations.

Here, since the IEEE 1609 communication protocol can provide an extended channel access mode (extended channel access mode) (as shown in FIG. 4 ), once the vehicle unit (OBU) installed in the vehicle 201 monitors the toll module 103 in the IEEE 1609 After the deduction service issued on the control channel (channel 178) provided by the communication protocol, the vehicle unit (OBU) installed in the vehicle 201 will go to the deduction service channel (channel 182) provided by the IEEE 1609 communication protocol. or another channel different from channel 182) to pay.

And, because the service period (service interval) of the deduction service channel (channel 182 or another channel different from channel 182) provided by the IEEE 1609 communication protocol is relatively long in the continuation channel access mode (due to being installed in The on-board unit (OBU) in the vehicle 201 does not need to monitor any services issued on the control channel (channel 178) provided by the IEEE 1609 communication protocol), so the on-board unit (OBU) installed in the vehicle 201 can The chargeback service channel (channel 182 or another channel different from channel 182) provided by the IEEE 1609 communication protocol is committed to paying (that is, to give the vehicle unit (OBU) installed in the vehicle 201 more time to Complete the deduction), and this is the meaning of the aforementioned "continuation of the deduction process". However, if the on-board unit (OBU) installed in the vehicle 201 still cannot complete the deduction in the post-deduction communication range F, the law enforcement unit must adopt the image of the vehicle 201 recorded in the law enforcement module 107 as a law enforcement basis for the certificate.

Based on the contents disclosed in the above exemplary embodiments, it can be seen that the electronic toll collection system 100 will communicate with the vehicle machine ( OBU) to communicate, so that the on-board unit (OBU) installed in the vehicle 201 is charged (deducted); in addition, the electronic toll collection system 100 will communicate with the device in a relatively small communication range (identification communication range A～D). The on-board unit (OBU) installed in the vehicle 201 communicates to capture the image of the vehicle 201 and obtain the identity information of the vehicle 201 .

In this way, the electronic toll collection system 100 can not only realize the goal of multi-lane free flow ETC (because the vehicle does not need to be on a fixed lane (the driving lane can be changed arbitrarily), but also does not need deliberate deceleration), and can accurately link the image of the vehicle with the identity information, thereby improving the efficiency and credibility of law enforcement (for vehicles driving on toll roads without paying tolls). In addition, because the electronic toll collection system 100 only uses a single open international standard communication protocol (that is, the IEEE 1609 communication protocol) to realize the charging and enforcement of multi-lane free traffic flow. Therefore, it will help to promote the development of industries related to toll roads in various countries.

It is worth mentioning here that although the above-mentioned exemplary embodiment uses the electronic toll collection system 100 to communicate with the on-board unit (OBU) installed in the vehicle 201 through the IEEE 1609 communication protocol, in other exemplary embodiments The electronic toll collection system 100 can also use other multi-channel network protocols to communicate with the on-board unit (OBU) installed in the vehicle 201, and these variant implementations are also intended to be protected by the present invention one of the categories.

On the other hand, based on the contents disclosed in the above exemplary embodiments, it can be seen that the configured operation process of the OBU installed in the vehicle 201 can be shown in FIG. 5 . In other words, the OBU installed in the vehicle 201 will execute the following process after being configured:

Judging whether to obtain the pre-debit service within the pre-debit communication scope (S501);

When the pre-deduction service is obtained in the pre-deduction communication range, the intermittent deduction procedure is performed, and at the same time, it is judged whether the identification service is obtained (S503);

When the identification service is obtained, the identity information of the vehicle is reported immediately and continuously until a preset time (the length of time is determined by the actual situation) (S505), otherwise, the intermittent deduction procedure is continued until the pre-deduction communication is left up to the range;

After reporting the identity information number of the vehicle, it is judged whether the intermittent deduction procedure is successful (S507);

When the intermittent deduction procedure is successful, it means that the deduction is completed (S509), otherwise, it is judged whether to obtain the post-deduction service in the post-deduction communication range (S511); and

When the post-deduction service is obtained in the post-deduction communication range, the continuation deduction procedure (S513) is performed to complete the deduction; otherwise, it is continuously judged whether the post-deduction service is obtained until leaving the post-deduction communication range.

It can be seen that the priority of the vehicle unit (OBU) installed in the vehicle 201 to report the identity information of the vehicle in response to the identification service is higher than that in response to the intermittent deduction process performed by the deduction service in advance. To put it simply, the on-board unit (OBU) installed in the vehicle 201 reports the identity information of the vehicle 201 prior to payment. In this way, even if the on-board unit (OBU) installed in the vehicle 201 has not completed deduction, the law enforcement unit can use the obtained identity of the vehicle 201 to make a complaint.

On the other hand, based on the content disclosed in the above exemplary embodiments, it can also be known that the configured operation process of the identification module 105 and the law enforcement module 107 of the electronic toll collection system 100 can be shown in FIG. 6 . In other words, the identification module 105 and law enforcement module 107 of the electronic toll collection system 100 will execute the following process after being configured:

Sensing whether the vehicle enters the identification communication range (S601);

Once it is sensed that the vehicle has entered the identification communication range, capture the image of the vehicle through a device capable of taking pictures, and start counting the time (S603), otherwise continue to sense whether the vehicle has entered the identification communication range;

At the same time/close to the time, send the identification service to the on-board unit (OBU) installed in the vehicle (S605), and judge whether the counted time exceeds a preset time (S607);

If it does not exceed the preset time described in step S607, then determine whether the vehicle unit (OBU) installed in the vehicle has reported the identity information of the vehicle (S609), otherwise, transmit the image of the captured vehicle (S611 ), thereby recording (S613); and

If the on-board unit (OBU) installed in the vehicle does not report the identity information of the vehicle, the identification service will be sent repeatedly to the on-board unit (OBU) installed in the vehicle until the preset time is exceeded; otherwise, it will be sent and linked The captured image and identity information of the vehicle (S615) are recorded (S613).

To sum up, the advantages of the electronic toll collection system 100 disclosed in the above exemplary embodiments are at least as follows:

1. The services released by the charging module and the identification module can be scheduled to ensure that the vehicle obtains the appropriate service at the appropriate time/time;

2. The OBUs in different vehicles can respond to the same identification service and report the identity information of their respective vehicles through different service channels, so there will be no collisions on the basis of communication, which can improve The success rate of the service, and at the same time can solve the problem of vehicles changing lanes arbitrarily, thus conforming to the concept of multi-lane free traffic flow;

3. Use a single open international standard communication protocol (IEEE 1609 communication protocol) to realize the charging and law enforcement of multi-lane free traffic flow (MLFF). Therefore, it will help to promote the development of industries related to toll roads in various countries;

4.

8. E-payment system as claimed in claim 5, wherein when this car machine withholds program success in this interval that this communication context of withholing in advance carries out, has then represented and has withholdd.

9. E-payment system as claimed in claim 5, wherein when this car machine to be withholdd procedure failure in this interval that this communication context of withholing in advance carries out, and this vehicle from this identification communication context enter to this withhold afterwards communication context time, control in this module based on this particular communication agreement and control this Charging Module in this control channel issue this withhold afterwards service to this car machine, use and make this car machine react on this service of afterwards withholing and carry out a continuity in this service channel of withholing and to withhold program, thus complete and withhold, or make this car machine react on this service of afterwards withholing and another service channel of withholing in those service channels to carry out this continuity and to withhold program, thus complete and withhold.

10. E-payment system as claimed in claim 3, wherein the agreement of this particular communication at least comprises IEEE 1609 communications protocol or has multichannel network convention.

11. 1 kinds of car machines, be installed in a vehicle, and it are configured to:

Judge whether to obtain one to withhold in advance service in a communication context of withholing in advance;

When have in this communication context of withholing in advance obtain this withhold in advance service time, then carry out an interval and to withhold program, and judged whether to obtain an identification service simultaneously;

When obtain this identification service time, then immediately and continue return this vehicle identity information to Preset Time, otherwise, continue to carry out this interval and withhold program to leaving this communication context of withholing in advance;

After the identity information of this vehicle of return, judge whether this interval program of withholing has successfully;

When this interval withholds program success, then represent and withholdd, otherwise, the service of withholing after the communication context that judges whether to withhold after a thing obtains a thing; And

When have in this communication context of afterwards withholing obtain this withhold afterwards service time, then carry out a continuity and to withhold program, used and withholdd, otherwise, continue to have judged whether to obtain this service of afterwards withholing to leaving this communication context of afterwards withholing,

Wherein this car machine is reached an agreement in a particular communication, and the control channel provided obtains this service of withholing in advance, this is withholdd afterwards and serves and this identification service;

This car machine identical or different service channel of withholing in this particular communication reaches an agreement on multiple service channels of providing is carried out withhold program and this continuity of this interval and to be withholdd program; And

One of them of the multiple identification service channels of this car machine in those service channels returns the identity information of this vehicle,

Wherein the frequency of this control channel and those service channels is different each other.

12. car machines as claimed in claim 11, wherein this car machine reacts on this identification service and the right of priority of returning the identity information of this vehicle reacts on this higher than this car machine and withholds in advance and serve this interval of carrying out and to withhold program.
