[0029] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0030] Please refer to Figure 1 and Figure 2 The control method of the single-lane multi-antenna electronic non-stop system of the application, the system comprises a plurality of outdoor units arranged along the driving direction of the lane; each outdoor unit corresponds to a communication area; the control method comprises the following steps:

[0031] S100, split the transaction process into several sub-transaction processes.

[0032] Specifically, the control unit 1 establishes at least one transaction thread, and splits the data reception and data transmission in each transaction thread into a sub-transaction process, and arranges them according to a complete transaction process, so that in each transaction process, it can be clearly displayed which sub-transaction process is being performed, so that it can be continued when the transaction is not completed.

[0033] S200, establish a transaction queue in a preset time period, wherein the queue information in the transaction queue includes outdoor unit number, target vehicle information, transaction state, and current sub-transaction process.

[0034] It can be understood that the control unit 1 establishes a transaction queue within a preset time period, for example, this time can be set to 30 minutes, the queue information in the queue will not be deleted within 30 minutes, and several outdoor units can query the queue information within the time period when establishing a link with the vehicle-mounted unit. Each transaction queue contains the following information: outdoor unit number (antenna head number), target vehicle information (vehicle-mounted unit network address, license plate number, vehicle information), transaction state (transaction completed, transaction in progress, transaction interrupted), and current sub-transaction process.

[0035] Specifically, the transaction queue is a list, which can record target vehicle information of a vehicle unit of a vehicle running in an electronic toll collection lane, and an outdoor unit number obtaining the target information, and record a transaction state corresponding to the target vehicle information and a current sub-transaction process; if the vehicle unit has never established a link with the outdoor unit, the transaction state is waiting for transaction, and the current sub-transaction process is an initial process or null.

[0036] More specifically, in order to prevent the target vehicle information obtained from being lost in the transaction queue, the queue information is added or deleted according to the target vehicle information obtained within a preset time period, for example, within 30 minutes, the target vehicle information obtained by a plurality of outdoor units and the corresponding queue are all recorded in the transaction queue, so that when the current outdoor unit does not complete the transaction with the vehicle unit, the subsequent outdoor unit adjacent to the current outdoor unit can still query the queue information corresponding to the target vehicle information in the transaction queue, facilitating the transaction.

[0037] S300, obtaining current target vehicle information of a current vehicle unit, and querying the transaction state and the current sub-transaction process corresponding to the current target vehicle information in the transaction queue.

[0038] Specifically, before establishing a link with the current vehicle unit, the queue information of the vehicle unit in the transaction queue is queried in advance, which can determine whether to establish a link with the vehicle unit; for example, before establishing a link with the vehicle unit, the transaction queue is queried according to the network address of the vehicle unit to obtain the transaction state and the current sub-transaction process of the vehicle unit; wherein the network address of the vehicle unit includes a MAC address or an IP address; for the vehicle unit which has not established a link, the current outdoor unit can be controlled to establish a link with it, for the vehicle unit in transaction or transaction completed, the current outdoor unit can be controlled to establish a link with other vehicle units, for the vehicle unit which has a special situation with the current outdoor unit, the subsequent outdoor unit adjacent to the current outdoor unit can be controlled to establish a link with the vehicle unit, and the transaction efficiency is significantly improved.

[0039] S400, according to the transaction state, controlling the current outdoor unit or the subsequent outdoor unit adjacent to it to continue to execute the current sub-transaction process according to a preset control logic, and updating the transaction queue in real time after completing each current sub-transaction process.

[0040] Specifically, after querying the transaction state, it can be determined whether to establish a link with the vehicle unit, and after establishing the link, the current sub-transaction process can be continued, and the plurality of outdoor units are cooperatively controlled by the control unit 1, avoiding repeated sub-transaction processes, and greatly improving the transaction efficiency.

[0041] It can be understood that the transaction process is divided into several sub-transaction processes; and a transaction queue within a preset time period is established, and the control unit 1 respectively continues to complete the sub-transaction process according to the preset control of the outdoor unit according to the transaction progress, and updates the queue information in real time after completing each current sub-transaction process, which greatly improves the transaction efficiency of the electronic non-stop parking system.

[0042] In some embodiments, the control method steps further include: the target vehicle information includes vehicle electronic identification information; the electronic barrier identifies the vehicle electronic identification information of the vehicle at the end of the lane driving direction, queries the transaction state corresponding to the vehicle electronic identification information in the transaction queue; judges whether the transaction state is completed; if yes, the electronic barrier is lifted to release the vehicle at the end; if not, the outdoor unit at the end of the lane driving direction and the vehicle-mounted unit at the end of the lane driving direction are connected according to the preset control logic, the current transaction process is continued to be executed, and the vehicle at the end of the lane driving direction is released after the transaction is completed.

[0043] It should be understood that the outdoor unit includes an antenna head and a communication bus connected to the antenna head, and the plurality of antenna heads are cooperatively controlled by the control unit 1, that is, the control unit 1 controls the plurality of antenna heads respectively, and it can also be understood that at least the antenna head at the front end of the lane driving direction and the antenna head adjacent to the front end and located at the rear end are controlled; by installing the plurality of antenna heads in the lane and arranging them according to the lane driving direction, the communication areas of the respective antenna heads can overlap, be separated, or be connected and distributed, for example, each antenna head is separated from the communication area of an antenna head by one antenna head (about 30 meters), and the last antenna head is installed at the existing position, that is, above the lane barrier, wherein the electronic barrier has a license plate number identification area, and the license plate number identification area is located in the communication area of the outdoor unit at the end of the lane driving direction.

[0044] Specifically, the electronic barrier has a vehicle information identification area, and the target vehicle information includes vehicle electronic identification information, which can be understood in this application as identifying the license plate number, and the vehicle information identification area is located in the communication area of the outdoor unit at the end of the lane driving direction, and the electronic barrier is connected with the control unit 1 for identifying the license plate number of the vehicle at the end of the lane driving direction and lifting or lowering the barrier according to the control instruction of the control unit 1; it can finally confirm whether the vehicle at the end of the lane driving direction has completed the transaction, and ensure that the vehicle can be released only after completing the transaction; this application cooperatively controls a plurality of outdoor units by a controller, which greatly improves the transaction efficiency, and identifies the license plate number of the vehicle at the end of the lane driving direction by the electronic barrier and lifts or lowers the barrier according to the control instruction of the control unit 1, which avoids missing the mark while greatly improving the traffic efficiency.

[0045] In some embodiments, the step of updating the queue information in real time after each completion of a current sub-transaction process comprises: if the target vehicle information of the current vehicle unit is not in the queue information, adding the target vehicle information to the transaction queue and updating the transaction queue in real time after completion of the current sub-transaction process; if the target vehicle information of the current vehicle unit is in the transaction queue, continuing to perform the current transaction process for a continued transaction and updating the transaction queue in real time after completion of the current transaction process.

[0046] Specifically, the outdoor unit sends a BST broadcast packet to request query of vehicle information data, the vehicle unit returns a vehicle signal, the outdoor unit receives the vehicle signal, queries a transaction queue, and checks a current transaction state of the vehicle unit; if the information of the vehicle unit is not in the transaction queue, a new transaction of the vehicle unit is performed, a link is established between the outdoor unit and the vehicle unit, communication with the vehicle unit is performed from the first step, a transaction thread is completed, vehicle information data such as a transaction state and a current sub-transaction process is sent to the control unit 1 every time a step is completed, and the control unit 1 adds or updates the transaction queue; if the transaction state of the vehicle unit is a transaction interruption state, a breakpoint continued transaction is performed, a link is established between the outdoor unit and the vehicle unit, communication with the vehicle unit is performed from a breakpoint step, a transaction thread is completed, and the transaction queue is updated in real time every time a step is completed.

[0047] In some embodiments, the transaction state comprises a waiting transaction, a transaction in progress, a transaction completion, and a transaction exception.

[0048] Specifically, the waiting transaction can be understood as a transaction that has not yet established a connection temporarily, the transaction in progress can be understood as a transaction that is being performed with the outdoor unit, the transaction completion can be understood as a successful transaction, and the transaction exception can be understood as a transaction interruption or a transaction timeout.

[0049] More specifically, when the outdoor unit establishes a link with the vehicle unit, if a single instruction response is timed out (default: 200 ms) and the transaction is timed out, the link is disconnected, at this time, the transaction state is a transaction interruption, and the transaction state is sent in real time.

[0050] In some embodiments, the step of controlling the current outdoor unit or a subsequent outdoor unit adjacent to the current outdoor unit to continue the current transaction process according to the transaction state and the preset control logic includes: if the transaction state of the current outdoor unit and the vehicle-mounted unit in the communication area is determined to be transaction completed, then controlling the current outdoor unit to establish a connection with other vehicle-mounted units in the communication area; if the transaction state of the current outdoor unit and the vehicle-mounted unit in the communication area is determined to be in transaction, then waiting for the transaction to be completed and then controlling the current outdoor unit to establish a connection with other vehicle-mounted units in the communication area; and if the transaction state of the current outdoor unit and the vehicle-mounted unit in the communication area is determined to be a transaction exception, then starting a subsequent outdoor unit adjacent to the current outdoor unit, controlling the subsequent outdoor unit to establish a connection with the vehicle-mounted unit, querying the current target vehicle information of the current vehicle-mounted unit in the transaction queue, continuing the current sub-transaction process for a subsequent transaction, and updating the transaction queue in real time.

[0051] Specifically, different control strategies are implemented according to different transaction states, the control unit 1 can cooperatively control a plurality of outdoor units, each transaction state corresponds to a different linking mode, and the subsequent outdoor unit can handle the transaction task that the current outdoor unit has not processed or that has a transaction exception, so as to prevent some outdoor units from being too busy; at the same time, the current transaction process is divided into a plurality of current sub-transaction processes, the current sub-transaction process is continued for a subsequent transaction, and the transaction queue is updated in real time, so as to significantly reduce the repetition of transaction steps and improve transaction efficiency.

[0052] In some embodiments, the step of controlling the outdoor unit at the end of the lane driving direction to establish a connection with the vehicle-mounted unit at the end of the lane driving direction according to the preset control logic includes: when the transaction state is in transaction, waiting for the transaction to be completed; when the transaction state is waiting for transaction or transaction exception, controlling the outdoor unit at the end to establish a connection with the vehicle-mounted unit at the end and continuing the current sub-transaction process.

[0053] In some embodiments, the step of controlling the current outdoor unit or a subsequent outdoor unit adjacent to the current outdoor unit to continue the current transaction process according to the transaction state and the preset control logic includes: if the transaction state of the current outdoor unit and the vehicle-mounted unit in the communication area is determined to be transaction completed, then controlling the current outdoor unit to establish a connection with other vehicle-mounted units in the communication area; if the transaction state of the current outdoor unit and the vehicle-mounted unit in the communication area is determined to be in transaction, then waiting for the transaction to be completed and then controlling the current outdoor unit to establish a connection with other vehicle-mounted units in the communication area; and if the transaction state of the current outdoor unit and the vehicle-mounted unit in the communication area is determined to be a transaction exception, then starting a subsequent outdoor unit adjacent to the current outdoor unit, controlling the subsequent outdoor unit to establish a connection with the vehicle-mounted unit, querying the current target vehicle information of the current vehicle-mounted unit in the transaction queue, continuing the current sub-transaction process for a subsequent transaction, and updating the transaction queue in real time.

[0054] Specifically, when the electronic barrier recognizes the license plate number of the vehicle of the on-board unit at the end of the lane driving direction, if the outdoor unit at the end of the lane is communicating with the on-board unit at the end, the transaction is continued until the transaction is completed; if the outdoor unit at the end is communicating with other on-board units, the transaction between the on-board units is interrupted; if the on-board unit at the end is in the transaction queue and the state is transaction interruption, the outdoor unit at the end is controlled to send a BST broadcast packet to search for the license plate number in the transaction queue, the outdoor unit at the end is controlled to establish a link with the on-board unit at the end and continue to complete the transaction; the transaction queue is updated after each step; if the license plate number of the vehicle of the on-board unit at the end is not in the transaction queue, the antenna head is controlled to send a BST broadcast packet to search for the on-board unit at the end and establish a link, a new transaction thread is created and completed; if the obtained license plate number is consistent with the license plate number of the vehicle in communication with the on-board unit at the end, the transaction is continued until the transaction is completed; after each step, the transaction state, the current transaction process and other vehicle information data are sent to the control unit 1 to control the information in the transaction queue.

[0055] Please refer to Figure 3 In another aspect, the application also provides a control device of a single-lane multi-antenna electronic non-stop parking system, comprising: a transaction process splitting module 18, used for splitting a transaction process into a plurality of sub-transaction processes; a transaction queue module 19, used for establishing a transaction queue in a preset time period, wherein the queue information in the transaction queue comprises an outdoor unit number, target vehicle information, a transaction state and a current sub-transaction process; a plurality of outdoor units arranged along a lane driving direction, the outdoor units being used for obtaining current target vehicle information of a current on-board unit and querying the transaction state and the current sub-transaction process corresponding to the current target vehicle information in the transaction queue; a control unit 1, used for controlling the current outdoor unit or a subsequent outdoor unit adjacent to the current outdoor unit to continue to execute the current sub-transaction process according to the transaction state and a preset control logic; and an updating module 20, used for updating the transaction queue in real time after each current sub-transaction process is completed.

[0056] Please refer to Figure 4Further, the outdoor unit is a plurality of units, and is arranged in the driveway and along the driving direction of the driveway. It can be understood as a plurality of antenna heads. The first outdoor unit 2 is arranged at the front end of the driving direction of the driveway, and the second outdoor unit 3 is arranged at the adjacent position of the first outdoor unit 2 and behind the first outdoor unit 2. The outdoor unit is used to establish a connection with the vehicle-mounted unit in the communication area, to obtain the vehicle-mounted signal of the vehicle-mounted unit, and to send the vehicle-mounted signal to the control unit 1. The control unit 1 is in communication connection with a data service module 15 and a service module 14. The control unit 1 controls the service module 14 to create and drive a transaction thread. The data service module 15 is used to complete the data interaction between the service module 14 and the control module and the hardware end 17. The hardware end 17 is the plurality of outdoor units.

[0057] Specifically, the outdoor unit is arranged as a plurality of units in the application. The outdoor unit includes an antenna head and a communication bus connected with the antenna head. The plurality of antenna heads are cooperatively controlled by a controller. Multiple sets of road side units are not needed to be installed. The traffic efficiency is improved, and the cost is reduced.

[0058] Please refer to Figure 6 Further, the control unit 1 is also connected with a power module 4, a consumer security storage module 5, a data storage module 6, an external communication bus interface 7, and a plurality of antenna bus interfaces for connecting ODU antennas. The power module 4 supplies power for the control unit 1 and the plurality of antenna bus interfaces. The consumer security storage module 5 is an external PSAM card, which can encrypt or decrypt the data received by the plurality of antenna bus interfaces. The data storage module 6 is a FLASH storage module, which is used for daily data recording, operation and maintenance data management, ODU antenna configuration file access, and the like. The antenna bus interface can provide power supply and communication control data bus for the outdoor unit.

[0059] In particular, the data service module 15 is in communication connection with the control unit 1 and the several outdoor units through the interface end 16. The data service module 15 includes an antenna sending thread, an antenna receiving thread, a consumption security storage sending thread, a consumption security storage receiving thread, a communication sending thread and a communication receiving thread. The antenna sending thread receives data sent by the transaction thread in the service module 14, calls the sending interface in sequence and sends out through the outdoor unit. When there is no transaction thread data to be sent, the BST broadcast package data is generated and the outdoor unit is called to send out. The data processing threads such as the antenna receiving thread, the consumption security storage receiving thread and the communication receiving thread are responsible for receiving the data of the corresponding thread received from the antenna interface, the consumption security storage interface and the communication interface respectively, and distributing the data to the corresponding transaction thread to drive the transaction. In particular, the antenna receiving thread creates a new transaction thread when receiving a new vehicle signal of a vehicle-mounted unit. The antenna receiving thread can receive data of all communication devices registered by software, analyze the data, and distribute the received data to the transaction thread after successful analysis.

[0060] More specifically, the service module 14 can create at least one transaction thread. The transaction thread is created when the antenna receiving thread receives a new vehicle signal of a vehicle-mounted unit, and is ended after the transaction is completed. After the transaction thread is established, the sending interfaces of the antenna sending thread, the consumption security storage sending thread and the communication sending thread are called to send data. The antenna receiving thread and the communication receiving thread take the network address of the vehicle-mounted unit as the key value, and distribute the data received by the thread to the current transaction thread for processing. Similarly, the transaction thread applies to use the consumption security storage module 5, and calls the consumption security storage module 5 to send data to the PSAM card. The consumption security storage module 5 receiving thread takes the assigned serial number as the key value to distribute the received data to the PSAM card, thereby driving the transaction process.

[0061] Please refer to Figure 5 In some embodiments, the outdoor unit includes a radio frequency transceiver front end 8 having an antenna head connected to the transmitting end. The radio frequency transceiver front end 8 is used to demodulate the received vehicle signal from a radio frequency signal to a baseband signal, or modulate the baseband signal to a radio frequency signal for sending out. A data decoding unit 9 is connected to the receiving end of the radio frequency transceiver front end 8, and is used to decode, filter and / or calibrate the baseband signal.

[0062] Specifically, the radio frequency transceiver front end 8 includes a 5.8G radio frequency transceiver front end link, which can realize conversion between 5.8G radio frequency signals and baseband signals; in the transmission mode, the baseband signals can be modulated into radio frequency signals; in the receiving mode, the 5.8G radio frequency signals can be demodulated into baseband signals; the data decoding unit 9 includes a data decoding module 11, a clock synchronization module 12 and / or a filter module 10, which are used for decoding the baseband signals, and filtering and / or calibrating the baseband signals, wherein the data decoding unit 9 is in communication connection with the control unit 1 through a serial data processing interface 13, and the clock synchronization module 12 supports clock synchronization to decode with actual clock to avoid decoding errors caused by inaccurate clock.

[0063] In one embodiment of the present application, the data decoding unit 9 includes a hardware digital filter module, a data decoding module 11 and a clock synchronization module 12 connected in sequence, the hardware digital filter module filters the received baseband signal S1 to obtain an input signal S2 after filtering out glitches less than 1us, which can improve the stability and reliability of the signal input to the decoding unit compared with the traditional decoding method; the clock synchronization module 12 supports clock synchronization and cooperates with the data decoding module 11 to decode with actual clock; in the present application, the output signal S3 of the data decoding module 11 includes three data control signals of clock clk, data data and chip select cs.

[0064] More specifically, the data decoding unit 9 adopts a multiplexer MUX array with multiple input and output, each signal output can be configured separately, and can realize signal edge to pulse conversion through digital filtering and signal polarity inversion of the input signal.

[0065] Further, after detecting the level change of the input signal S2, the clock synchronization module 12 starts timing, judges transaction or transaction interruption through a preset first comparison value, if the level change occurs when the timing time of the clock synchronization module 12 does not exceed the preset first comparison value, it is considered that the data is 0 and can be judged as transaction interruption; otherwise, it is considered that the data is 1 and can be judged as transaction, at this time, the output signal s3 outputs the chip select cs signal and the clock clk to the control unit 1, and sends this data to the data signal.

[0066] Further, a preset second comparison value is provided at the same time, wherein the second comparison value is greater than the first comparison value and is used for detecting timeout, if the timing time of the clock synchronization module 12 exceeds the second comparison value, it means that the data has error or has stopped receiving data, at this time, the chip select cs signal is pulled up and the data decoding unit 9 is reset, if the level change is detected again within the second comparison value, it is considered that the next data transmission starts.
