Description

Technical Field

[0001] The present invention relates to the field of Internet of Things and highway toll technology, and in particular to a highway self-service lane passing method and system based on the Internet of Things. Background Art

[0002] Now, more and more highway toll stations adopt the design concept of "no booth" in accordance with the idea of ​​saving and intelligence. The self-service lanes of highway toll stations rely on a variety of advanced equipment and technologies such as license plate capture equipment, vehicle type recognition equipment, integrated barrier machines, self-service card issuing machines, self-service payment machines, road side units (RSU), etc., to realize a diversified toll station system of unmanned self-service card collection, self-service payment, and electronic toll collection (ETC).

[0003] Figure 1 It is a typical layout of an existing self-service lane system behind the highway barrier. This system is suitable for the entrance and exit of highway toll stations. At the entrance of the toll station, the self-service card issuance / payment device is used as a card issuance device; at the exit of the toll station, the self-service card issuance / payment device is used as a payment device. Take the toll station exit as an example. After the vehicle enters the lane, it first triggers the vehicle model recognition device to identify the vehicle model, license plate and other information. After the vehicle reaches the RSU transaction area, the vehicle with ETC installed will automatically communicate with the roadside unit through the on-board unit to complete the transaction. Vehicles without ETC installed can obtain the CPC card with the identified vehicle information written on it at the payment device, calculate the toll based on the identified information and the information in the CPC card, and complete the transaction through flexible payment methods such as mobile payment and code scanning payment. The vehicle then triggers the vehicle inspection coil (i.e. Figure 1 The vehicle passes through the coil in the vehicle, and the lane camera captures the image. The backend determines the transaction result based on the license plate and controls the information display screen to display the vehicle passing information. The barrier is controlled based on the transaction result of the lead vehicle. If the transaction is successful, the barrier is lifted and the vehicle triggers the vehicle passing coil. The backend determines that the vehicle has left based on the signal reported by the coil. The barrier is controlled and information is displayed based on the transaction result of the next vehicle.

[0004] Self-service lanes are generally unmanned and do not require the installation of ETC. Drivers and passengers can directly use non-cash methods such as mobile payment or card swiping to pay by themselves, which can realize quick payment based on the Internet of Things on highways. However, when the vehicle in the self-service lane fails to pass due to various reasons, manual remote processing is required. For some transaction failures caused by equipment failures, toll collectors do not understand the relevant technology and cannot handle them in time, which will reduce the efficiency of the self-service lane and easily cause congestion at the toll station during peak traffic. Existing technologies cannot solve the problem of lanes being unusable when self-service card issuance / payment equipment fails.

[0005] In addition, the existing technology cannot solve the problem that the following vehicle cannot be identified due to no changes in the vehicle inspection. The arrival or departure of the vehicle is usually detected based on the signal of the vehicle sensing coil buried underground. When the vehicle drives above the vehicle sensing coil, it will trigger the vehicle sensing coil to generate a signal, at this time it can be judged that there is a vehicle; and when the vehicle drives away from the vehicle sensing coil, the coil signal disappears, and it is judged that there is no vehicle. However, since the width of the coil is more than 0.5 meters, when the rear vehicle closely follows the front vehicle, it is possible that the front vehicle has not completely left the coil, but the rear vehicle has already driven onto the coil. In this way, it is impossible to accurately distinguish whether the front vehicle has not left or the rear vehicle has arrived.

[0006] Therefore, how to achieve efficient passage on the self-service lanes of highways is a problem to be solved. Summary of the invention

[0007] In view of the shortcomings of the existing technology, this method proposes an efficient passage method and a high-availability system for self-service lanes on highways based on the Internet of Things to eliminate or improve one or more defects in the existing technology.

[0043] In order to solve the problem in the prior art that the lane cannot be used due to a card machine failure, the present invention provides an efficient passage method and efficient passage system for a highway self-service lane based on the Internet of Things. The efficient passage system adopts the following Figure 2The self-service lane duplex self-service system shown in the figure includes: lane equipment, lane service system and station-level system arranged for the same physical lane, wherein the lane equipment includes: vehicle type recognition equipment, self-service card issuance / payment equipment (including front self-service card issuance / payment equipment and rear self-service card issuance / payment equipment), lane camera (including front lane camera and rear lane camera), RSU and integrated integrated equipment including vehicle inspection unit (such as vehicle induction coil, etc.), rear-mounted barrier, fee display device (referred to as fee display) and alarm, etc.; wherein the vehicle inspection unit may include a first vehicle inspection unit (such as a first vehicle inspection unit corresponding to the rear self-service card issuance / payment equipment) Figure 2 Vehicle inspection 1), and the second vehicle inspection unit corresponding to the front self-service card issuance / payment device (such as Figure 2 The vehicle inspection 2 in the vehicle inspection unit 2) and the third vehicle inspection unit for triggering the rear barrier to rise and fall (such as Figure 2 Vehicle inspection 3), the vehicle inspection unit can be a vehicle induction coil, but the present invention is not limited to this, and can also be other types of vehicle inspection devices. The lane service system includes two field control service subsystems (i.e., the front field control service subsystem and the rear field control service subsystem) and two self-service front-end service subsystems (i.e., the front self-service front-end service subsystem and the rear self-service front-end service subsystem); the station-level system includes: a transaction service subsystem and an Internet of Things subsystem, wherein the transaction service subsystem is used to store transaction data, receive transaction requests and process transaction requests based on transaction data, and the Internet of Things subsystem is used to provide Internet of Things communication services between the various subsystems of the lane service system. Data transmission between the lane equipment and the various subsystems of the lane service system can be carried out through the TCP transmission protocol. The front field control service subsystem is used to control the front lane camera, and the rear field control service subsystem is used to control the rear lane camera, RSU and integrated integrated equipment. The front self-service front-end service subsystem is used to control the front self-service card issuance / payment equipment, and the rear self-service front-end service subsystem is used to control the rear self-service card issuance / payment equipment. In the embodiment of the present invention, the front / rear outfield control service subsystem and the front / rear self-service front-end service of the lane service system can be implemented by a computer program deployed on a server at a toll booth.

[0044] Figure 3 FIG. 1 is a schematic diagram showing the layout of lane equipment on a highway in a self-service lane duplex self-service system in an embodiment of the present invention. Figure 3 The equipment layout shown is similar to Figure 1 Compared with the layout shown in FIG. 1 , a self-service card issuing / payment device (i.e., the front self-service card issuing / payment device) and a vehicle inspection coil corresponding to the front self-service card issuing / payment device (i.e., Figure 3 2) and a lane camera (i.e. Figure 3 In the lane service system, the front lane camera is added, and the front off-site control service subsystem and the front self-service front-end service subsystem are added accordingly. Figure 3Among the three vehicle inspection coils (referred to as vehicle inspection) 1-3 shown in the figure, vehicle inspection 1 and 2 are used as existence coils, and vehicle inspection 3 is used as a passing coil.

[0045] The "front" and "rear" in the front self-service card issuance / payment device, the rear self-service card issuance / payment device, the front lane camera and the rear lane camera shown in the figure are defined in the following way: if there are two devices of the same type in the lane equipment, according to the direction of vehicle travel, the device that the vehicle arrives at first is the front, and the device that the vehicle arrives at later is the rear, such as Figure 3 shown.

[0046] based on Figure 2 and Figure 3 The system and device layout shown in the figure, the efficient highway self-service lane passing method based on the Internet of Things in the embodiment of the present invention is as follows Figure 4 The following steps are shown:

[0047] Step S110, obtain the vehicle type identification information of the vehicle entering the toll station, and report the vehicle type identification information to the rear external field control service subsystem through the TCP transmission protocol, and the rear external field control service subsystem sends it to the corresponding rear self-service front-end service subsystem through the Internet of Things, and forwards it to the front self-service front-end service subsystem through the Internet of Things according to a preset forwarding strategy (first forwarding strategy).

[0048] In one embodiment of the present invention, the vehicle type identification information can be obtained by a vehicle type identification device. The vehicle type identification device can be, for example, an existing vehicle type identification device, such as a vehicle type identification integrated device based on a laser radar, etc. Since it does not belong to the improvement point of the present invention, it will not be described here. After the vehicle type identification device obtains the vehicle type identification information, the vehicle type identification information can be reported to the rear field control service subsystem through the TCP transmission protocol, and the rear field control service subsystem sends it to the rear self-service front-end service through the Internet of Things, and forwards it to the front self-service front-end service through the Internet of Things according to a preset forwarding strategy, such as Figure 5 shown.

[0049] In the embodiment of the present invention, the forwarding strategy can be pre-configured on the Internet of Things. Although the front self-service card issuing / payment device and the rear self-service card issuing / payment device in the present invention are used to issue cards and pay fees for vehicles from the same lane, in the embodiment of the present invention, the lane can be virtualized as two lanes, corresponding to the front self-service front-end service subsystem (it can also be said to correspond to the front self-service card issuing / payment device) and the rear self-service front-end service subsystem (it can also be said to correspond to the rear self-service card issuing / payment device), that is, the front self-service card issuing / payment device and the rear self-service card issuing / payment device in the self-service lane duplex self-service system of the present invention process the card issuing or payment of the vehicle in the corresponding lane under the control of the corresponding front self-service front-end service subsystem and the rear self-service front-end service subsystem, but share the vehicle model identification device and the integrated integrated device. Therefore, in the embodiment of the present invention, the forwarding strategy of the vehicle model identification information is to modify the lane of the vehicle in the message carrying the vehicle model identification information to the lane corresponding to the corresponding front self-service front-end service subsystem, so that the front self-service front-end service subsystem obtains the vehicle model identification information of the vehicle on the corresponding lane and triggers the front self-service card issuing / payment device.

[0050] Therefore, in one embodiment of the present invention, the forwarding strategy is to modify only the lane identification information (such as lane number) in the forwarded message carrying the vehicle identification information, without modifying the message content. As an example, when the lane number is carried in the subject of the message, only the subject of the message can be modified without modifying the message content. For example, the subject of the vehicle identification message sent by the rear field control service subsystem to the rear self-service front-end service subsystem through the Internet of Things can be "WL / 65 / G300365 / G300365 / 65012509 / 6501250968 / Push / DevInfo / Axle", where the fields separated by " / " represent the fixed value (WL), province code, road company number, section number, toll station HEX number, lane HEX number, fixed value ( / Push / DevInfo / Axle) in turn, that is, in the field "6501250968", "65012509" represents the toll station number, and "68" is the lane number corresponding to the rear self-service card issuance / payment device. The topic forwarded by the back field control service subsystem to the front self-service front-end service subsystem through the Internet of Things is modified to "WL / 65 / G300365 / G300365 / 65012509 / 6501250970 / Push / DevInfo / Axle", that is, only the lane number is modified to the lane number corresponding to the front self-service card issuance / payment device, and the content of the message does not need to be modified. This forwarding strategy can be implemented by pre-configuring SQL rules on the Internet of Things. By matching the topic and content, messages with consistent content matching are forwarded to the same type of topics with different lane identifiers.

[0051] In the embodiment of the present invention, the lane numbers corresponding to the front self-service card issuing / payment device and the rear self-service card issuing / payment device may be pre-assigned.

[0052] Step S120, the license plate recognition information of the vehicle obtained by the front lane camera and the rear lane camera is reported to the corresponding front outfield control service subsystem and rear outfield control service subsystem through the TCP transmission protocol, and the front outfield control service subsystem and the rear outfield control service subsystem respectively send it to the corresponding front self-service front-end service subsystem and rear self-service front-end service subsystem through the Internet of Things.

[0053] That is, the license plate recognition information obtained by the camera in the front lane when capturing the license plate of the vehicle is reported to the corresponding front outfield control service subsystem through the TCP transmission protocol, and the corresponding front outfield control service subsystem sends it to the corresponding front self-service front-end service subsystem through the Internet of Things. The license plate recognition information obtained by the camera in the rear lane when capturing the license plate of the vehicle is reported to the corresponding rear outfield control service subsystem through the TCP transmission protocol, and the corresponding rear outfield control service subsystem sends it to the corresponding rear self-service front-end service subsystem through the Internet of Things, such as Figure 6 shown.

[0054] Step S130, after identifying the vehicle inspection signal of the vehicle inspection unit (with a coil) corresponding to the front self-service card issuing / payment device, the vehicle inspection signal is reported to the rear external field control service subsystem through the TCP transmission protocol, and the rear external field control service subsystem sends it to the corresponding rear self-service front-end service subsystem through the Internet of Things, and forwards it to the front self-service front-end service subsystem through the Internet of Things according to a preset forwarding strategy (second forwarding strategy), so that the front self-service front-end service subsystem triggers the front self-service card issuing / payment device to issue a transaction request to conduct a transaction.

[0055] exist Figure 2 and Figure 3 In the example shown, the existence coil corresponding to the front self-service card issuance / payment device is vehicle inspection 2. After the moving vehicle presses on vehicle inspection 2, the integrated device recognizes the vehicle inspection signal through vehicle inspection 2, and reports the recognized vehicle inspection signal to the rear field control service subsystem through the TCP transmission protocol. The rear field control service subsystem shares it to the rear self-service front-end service subsystem through the Internet of Things. At the same time, the vehicle inspection signal is forwarded to the front self-service front-end service subsystem through the pre-configured forwarding strategy.

[0056] The present invention adds a dynamic content forwarding strategy based on the existing vehicle inspection signal reporting process. The dynamic content forwarding strategy can be configured in advance on the Internet of Things. After the rear field control service subsystem pushes the vehicle inspection information to the Internet of Things, the Internet of Things modifies the forwarding topic and content of the vehicle inspection signal message with the vehicle inspection sequence number 2 and shares it to the front self-service front-end service subsystem according to the pre-configured forwarding strategy. Figure 7 shown.

[0057] The forwarding strategy in the vehicle inspection signal reporting process is different from the forwarding strategy in the vehicle model identification information reporting process. The forwarding strategy in the vehicle model reporting process is to transform the content of one topic into the content of another topic for forwarding, that is, only the topic is changed, not the content. The forwarding strategy in the vehicle inspection signal reporting process is to modify both the subject and the content. The lane identification in the subject sent to the rear external field control service subsystem (such as the lane number corresponding to the rear self-service card issuing / payment device) is modified to the lane identification (such as the lane number) corresponding to the front self-service card issuing / payment device, and the identification of the existing coil corresponding to the front self-service card issuing / payment device in the corresponding content (such as vehicle inspection serial number 2) is modified to the identification of the existing coil set for the self-service card issuing / payment device in the current vehicle inspection signal reporting process (such as vehicle inspection serial number 1), that is, the vehicle inspection serial number in the message content is changed to 1 and forwarded to the front self-service front-end service subsystem, so that there is no need to change the existing method for identifying the existing coil in the vehicle inspection signal reporting process. The front self-service front-end service subsystem can identify the vehicle inspection signal of the existing coil and trigger the corresponding front self-service card issuing / payment device to issue or collect cards and request payment.

[0058] The original topic corresponding to the vehicle inspection signal information sent by the rear field control service subsystem to the rear self-service front-end service subsystem through the Internet of Things is:

[0059] WL / 65 / G300365 / G300365 / 65012509 / 6501250968 / Push / DevInfo / VeDetector

[0060] The vehicle inspection content under this topic contains an index field indicating the vehicle inspection serial number. Original vehicle inspection serial number:

[0061] Original vehicle inspection serial number: index=2.

[0062] When the rear field control service subsystem forwards the vehicle inspection signal information to the front self-service front-end service subsystem through the second forwarding strategy via the Internet of Things, the modified new topic becomes:

[0063] WL / 65 / G300365 / G300365 / 65012509 / 6501250970 / Push / DevInfo / VeDetector;

[0064] The vehicle inspection content mainly modifies one field index (vehicle inspection serial number), and the modified new vehicle inspection serial number is: index=1.

[0065] This forwarding strategy can be implemented by pre-configuring SQL rules on the Internet of Things. By matching the subject and content, the vehicle inspection number in the message content with consistent content matching (modified to the vehicle inspection number set for the self-service front-end service in the current vehicle inspection signal reporting process) is modified and forwarded to the same type of topic with different lane markings.

[0066] It should be noted that the vehicle inspection number 2 in the above example is for reference only. Figure 2 and Figure 3 The lane layout diagram in the vehicle inspection sequence number is determined by the lane layout diagram in the vehicle inspection sequence number. The actual lane layout vehicle inspection sequence number can also be configured as other values, and the present invention is not limited to this.

[0067] Thus, the self-service card issuing / payment equipment at the entrance of the highway toll station can be triggered to issue the card, and the self-service card issuing / payment equipment at the exit of the highway toll station can be triggered to collect the card and pay the fee.

[0068] Step S140, after the first vehicle inspection unit (i.e., vehicle inspection 1) corresponding to the rear self-service card issuing / payment device generates a vehicle inspection signal for the vehicle, the vehicle inspection signal is reported to the rear external field control service subsystem through the TCP transmission protocol, and the rear external field control service subsystem sends it to the rear self-service front-end service subsystem through the Internet of Things to control the rear self-service card issuing / payment device to determine whether the current vehicle transaction is completed based on the vehicle information, execute the transaction if it is determined that the current vehicle transaction is not completed, and control the raising and lowering of the barrier after it is determined that the transaction is completed.

[0069] After the vehicle drives to the vehicle inspection 1 position corresponding to the rear self-service card issuance / payment device and triggers the vehicle inspection 1 vehicle inspection signal, if the rear self-service card issuance / payment device determines that the card has been issued (at the entrance) or the transaction has been completed (at the exit) based on the vehicle's license plate information, it directly triggers the barrier to lift and release. If it is determined based on the license plate that the card has not been issued or the transaction has not been completed, the card issuance or payment process is executed. This process can be the same as the existing card issuance or payment process, and will not be repeated here.

[0070] That is, in this step, after the rear self-service front-end service subsystem receives the vehicle inspection signal, it triggers the rear self-service card issuance / payment device to start, and when it is determined based on the vehicle information that the current vehicle transaction has been completed, the barrier is directly lifted to release it. If it is confirmed that the transaction has not yet been completed, the corresponding card issuance or collection and payment request operations can be performed, and the barrier is lifted to release it after completion. Once the transaction is successfully confirmed, the lane service system will immediately control the integrated barrier machine through the network, instructing it to lift the barrier, display the vehicle traffic information, and allow the vehicle to enter or leave the highway smoothly. This series of automated operations not only improves the traffic efficiency, but also greatly enhances the accuracy and convenience of charging.

[0071] Transaction and release at the rear self-service card issuing / payment device: When the vehicle arrives at the rear self-service card issuing / payment device, the rear self-service card issuing / payment device starts the entry card issuing or exit payment transaction under the control of the rear self-service front-end service subsystem. First, determine whether the transaction is successful based on the license plate. If successful, lift the barrier to release the vehicle; if unsuccessful, continue to initiate transactions until the barrier is lifted to release the vehicle after the transaction is successful.

[0072] In addition, in an embodiment of the present invention, a card can be inserted at the front self-service payment device at the highway exit, and a transaction can be conducted at the rear self-service payment device. More specifically, when the vehicle arrives at the front self-service payment device, the exit transaction process is started. The front self-service subsystem controls the front self-service payment device to extend a telescopic arm, receive the CPC card inserted by the vehicle's passengers and read the card information. If the vehicle leaves the coil (i.e., vehicle inspection 2) before completing the transaction, the vehicle information is shared to the rear self-service front-end service through the Internet of Things. When the vehicle arrives at the rear self-service payment device, the rear self-service payment device determines whether the transaction is successful based on the license plate. If successful, the barrier is lifted to release the vehicle; if the transaction is judged to have failed, the vehicle data shared by the front self-service to the rear self-service front-end service through the Internet of Things is obtained, the exit billing transaction is restarted, and the exit transaction is completed at the rear self-service payment device. After the transaction is successful, the barrier is lifted to release the vehicle.

[0073] Therefore, the method of the present invention may further include the following steps: after the vehicle leaves the vehicle inspection unit (i.e., vehicle inspection 2) corresponding to the front self-service card issuance / payment device, the vehicle information is shared to the rear self-service front-end service through the Internet of Things, and the vehicle information may include information such as vehicle model, license plate, and transaction status. In this way, the rear self-service front-end service can obtain vehicle-related information in the first place and trigger the self-service card issuance / payment device to perform corresponding operations.

[0074] Based on the above-mentioned highway self-service lane duplex self-service system based on the Internet of Things and the corresponding self-service lane efficient passage method, by adding self-service card issuing / payment equipment, coils and lane cameras to the lane, and adding a self-service front-end service and an external field control service to the lane service system, it is possible to realize multiple vehicles to collect cards / pay fees at the same time, and when one self-service card issuing / payment equipment fails, another self-service card issuing / payment equipment can continue to work, thereby ensuring the normal operation of the lane, and reducing the special situation rate, greatly improving the lane passage efficiency of the toll station and the probability of transaction failure. The method of the present invention can be used at the highway entrance, after the card issuing device collects the card; at the highway exit, the card can be paid at the front payment machine and the rear payment machine can be released; the card can also be inserted at the front payment machine and the rear payment machine can be paid and released. The present invention can realize multiple vehicles to collect cards / pay fees at the same time, and when one device fails, the other can continue to work, ensuring the normal operation of the lane.

[0075] In the embodiment of the present invention, after the front self-service subsystem successfully completes the transaction, the rear self-service subsystem releases the vehicle: when the vehicle arrives at the front self-service card issuance / payment device, the entry card issuance or exit payment transaction is automatically started. After the vehicle leaves the corresponding coil of the front self-service card issuance / payment device, the vehicle information is shared to the rear self-service front-end service subsystem through the Internet of Things. When the vehicle arrives at the rear self-service card issuance / payment device, it determines whether the transaction is successful based on the license plate. If successful, the barrier is lifted to release the vehicle.

[0076] The method and system of the present invention are not only applicable to MTC vehicles, but also to vehicles equipped with ETC. For vehicles equipped with ETC, transactions at the entrance and exit do not require card issuance and return, and transactions are directly realized through interaction between the OBU in the vehicle and the RSU arranged on the lane.

[0077] Figure 8 The figure is a schematic diagram of the business process of the self-service lane duplex self-service system at the entrance of the toll station in one embodiment of the present invention. Fig. 9 This is a schematic diagram of the business process of the self-service lane duplex self-service system at the toll station exit in one embodiment of the present invention. Figure 8 As shown, under normal conditions, the front self-service front-end service subsystem is in operation, and the front self-service card issuing device at the entrance of the toll station is also called a self-service card issuing machine. When the vehicle arrives at the vehicle model detection area and license plate detection area at the entrance of the toll station and the vehicle model and license plate are detected and reported respectively, the front self-service front-end service subsystem receives the vehicle model identification information and license plate identification information, and immediately starts a series of automated processes when the vehicle inspection 2 is triggered. First, the front self-service front-end service subsystem controls the self-service card issuing machine to perform the entry transaction process, prompting the passenger to press the key to take the card. After the passenger presses the key to send a card retrieval request, the front self-service front-end service subsystem determines whether the vehicle information is complete, and if it is confirmed to be complete, the specific information of the vehicle (including but not limited to the license plate number, vehicle model, etc.) and the relevant information of the toll station are accurately written into the highway composite pass card (CPC card). After confirming that the transaction is successful (the information is written successfully), the card is issued to the passenger. After the vehicle inspection 1 is triggered in the car, the rear self-service card issuing device confirms whether the transaction is successful based on the vehicle information, and controls the lifting of the barrier to release the vehicle if the transaction is successful, and continues to initiate the transaction request and wait for the transaction to be completed if the transaction is confirmed to be incomplete. If the vehicle information is found to be incomplete before the CPC card information is written or the transaction fails after the self-service card issuance device confirms the transaction, special processing will be carried out. Fig. 9As shown, under normal conditions, the front self-service front-end service subsystem is in operation. The front self-service card issuing device at the toll station exit is also called a self-service payment machine. When the vehicle arrives at the toll station at the exit of the expressway and arrives at the vehicle type detection area and license plate detection area at the toll station exit and the vehicle type and license plate are detected and reported respectively, the front self-service front-end service subsystem receives the vehicle type identification information and license plate identification information, and immediately starts a series of automated processes when the vehicle inspection 2 is triggered. First, the front self-service front-end service subsystem controls the self-service card issuing machine to carry out the exit transaction process and prompts the passengers to hand in the card. After the passengers hand in the card, the information in the CPC card held by the vehicle is read. This information has been accurately written when the vehicle enters the expressway, including key data such as the license plate number, vehicle type, and entrance toll station. Based on the read information, the front self-service front-end service subsystem controls the self-service payment machine to initiate an exit transaction request, and calculates the toll to be collected according to the actual driving path and charging standards of the vehicle. If the transaction is successfully completed, the front self-service front-end service subsystem will update the status information in the CPC card, and upload the transaction results and related information to the background management system for recording and settlement. After the vehicle triggers vehicle inspection 1, the rear self-service card issuing device confirms whether the transaction is successful based on the vehicle information, and controls the lifting of the barrier to release the vehicle if the transaction is confirmed to be successful. If the transaction is not completed, it will continue to initiate a transaction request and wait for the transaction to be completed. If the vehicle information is incomplete when reading the CPC card, or the identified vehicle information does not match the information read from the CPC card, or if the rear self-service card issuing device confirms that the transaction failed, special processing will be performed.

[0078] Furthermore, in order to solve the problem that the following vehicle cannot be identified due to no changes in the vehicle inspection, in the embodiment of the present invention, the vehicle following logic is improved, and the transaction vehicles are recorded using the transaction queue, the queue to be left and the queue that has left, that is, the "queue that has left" and the "queue to be left" are added to the recorded vehicle queue. The vehicle that started the transaction but failed to successfully complete the transaction is added to the transaction queue; the vehicle that successfully completed the transaction and did not leave the third vehicle inspection unit is added to the queue to be left; the vehicle that successfully completed the transaction and left the third vehicle inspection unit is removed from the queue to be left and added to the queue that has left.

[0079] More specifically, after the vehicle leaves and passes through the coil (vehicle inspection 3), the vehicle that has left is added to the "left queue", and the data of the left queue is cached for 30 minutes. In addition, after determining that the vehicle transaction is successful, it is further determined whether the vehicle is in the left queue. If the vehicle is, it will not be added to the queue to be left. If the vehicle is not in the left queue, the vehicle will be placed in the queue to be left. When the vehicle leaves and passes through the coil (vehicle inspection 3), the first vehicle is removed from the queue to be left and added to the queue to be left. After the removal, if the queue to be left is empty, the barrier is lowered. Among them, the situations of successful transaction include: successful card collection, successful payment, successful ETC transaction or license plate recognition re-release, among which license plate recognition re-release includes the following situations: (1) After the transaction is successful at the front self-service card issuing machine / self-service payment machine, when the vehicle arrives at the rear self-service card issuing machine / self-service payment machine, the rear self-service card issuing machine / self-service payment machine will determine whether the transaction is successful based on license plate recognition. If the transaction is successful, it will lift the barrier to release the vehicle; (2) When the vehicle successfully completes the transaction in a lane but does not exit and enters another lane, it will also determine whether the transaction is successful based on license plate recognition. If the transaction is successful, the rear self-service card issuing machine / self-service payment machine will lift the barrier to release the vehicle.

[0080] In addition, the present invention also corrects the queue to be left: if a vehicle is currently trading and there is no signal passing through the coil, it means that the vehicles in front have left and there are no vehicles to be left. In this case, it is further determined whether there are any vehicles in the queue to be left. If there are any vehicles, the queue to be left is cleared.

[0081] In addition, in the embodiment of the present invention, on the basis of the original method of judging whether the vehicle has left by judging whether the vehicle has left through the coil, the method of assisting in judging whether the vehicle has left by license plate recognition is further added. If the lane camera can capture the license plate of the rear vehicle and report it, it can be judged that the front vehicle has left and the rear vehicle has arrived. Therefore, it can be determined whether the front vehicle has left based on whether the rear vehicle license plate report is received. In other words, after receiving the new license plate recognition information, the self-service front-end service subsystem believes that the front vehicle has left the current self-service card issuance / payment device, so the information of the previous vehicle can be cleared in the queue to be left, and the received license plate identification can be assigned to the head vehicle in the transaction queue. If the head vehicle successfully completes the transaction and leaves the coil, the head vehicle is placed in the queue to be left. If the head vehicle leaves through the coil, the head vehicle information in the queue to be left is cleared and placed in the queue that has left.

[0082] In the existing vehicle following logic, the current lane only judges the current vehicle, and there is no queue for transactions. The arrival or departure of the vehicle is judged based on the signal passing through the coil. However, since the width of the coil is more than 0.5 meters, when the rear vehicle closely follows the front vehicle, it is possible that the front vehicle has not completely left the coil, but the rear vehicle has already driven onto the coil. In response to this situation, if the signal passing through the coil does not change, and the lane camera captures the license plate of the rear vehicle and reports it, it can be judged that the front vehicle has left and the rear vehicle has arrived, which effectively solves the problem of no change in the vehicle following inspection.

[0083] In the prior art, when following a vehicle, it is impossible to rely on vehicle inspection to distinguish whether the vehicle has left. The system of the present invention uses license plate recognition + vehicle inspection in multiple dimensions to distinguish whether the vehicle has arrived or left, greatly reducing the special situation of no license plate.

[0084] Most current technologies create transaction queues based on license plate recognition signals and vehicle inspection signals. One vehicle inspection + one license plate corresponds to one vehicle, which is strongly dependent on the vehicle inspection signal. If the vehicle inspection signal does not change, the queue will be chaotic and subsequent transactions may go wrong. For example, if the queue is ABCD, after transaction A, because the vehicle inspection has not changed or has changed multiple times, it may appear that the current transaction is for vehicle B, but the actual transaction is for vehicle C. In an embodiment of the present invention, by adding "queues that have left" and "queues to leave" to the recorded vehicle queue, the confusion of the queue is greatly reduced. In addition, by using license plate recognition + vehicle inspection in multiple dimensions to distinguish whether the vehicle has left, the special situation of no license plate is greatly reduced.
