Further, the vehicle passing system comprises a configuration server for configuring various types of white lists. The various types of whitelists may include a fixed whitelist and a dynamic whitelist.
Fixed parking cards (hereinafter referred to as 'parking cards') issued by a common parking lot are issued to license plate numbers with known regional authorities, and the parking cards are divided into monthly cards, parking space cards and visitant cards; the monthly card is generally limited by the validity period, the parking space card is limited by the validity period and the number of the vehicles, and the honored guest card is generally not limited by conditions; and the vehicle passing system automatically counts the parking cards meeting the requirements of each lane in each area at regular time to generate a fixed white list.
When the vehicle passing system is in operation, a dynamic white list is generated according to vehicle entering and exiting information and some configuration information, wherein the dynamic white list comprises newly configured valid data which can be added into the white list, license plate numbers which do not need to be charged within a specified time after dynamic charging, temporary authorization data managed by other clients and the like; dynamic white lists require periodic refreshing.
When the recognized license plate numbers transmitted by the lane camera are received, matching the license plate numbers and lane identifications with the two white lists in the cache, matching image recognition time with the validity period in the corresponding white list, directly sending an opening instruction if the matching is successful, and then carrying out conventional business data processing of entering and exiting the parking lot; if the matching is not successful, performing conventional service data processing on the parking lot, wherein the processing result is a brake opening instruction which is sent according with the brake opening condition; the business data processing of entering and exiting the parking lot relates to multiple IO reading, complex business judgment, business data storage and the like, and is time-consuming.
When receiving the recognized license plate number transmitted by the lane camera, the fixed white list and the dynamic white list can be checked at the same time, or the priority of the white list is configured, so as to determine the checking sequence of the white list, for example, when the priority of the fixed white list is higher than that of the dynamic white list, the fixed white list needs to be checked first to match the license plate number with the lane identifier, and if the fixed white list cannot be successfully matched, the dynamic white list is checked; or, when the priority of the fixed white list is lower than that of the dynamic white list, the dynamic white list needs to be checked first to match the license plate number and the lane identifier, and if the dynamic white list cannot be successfully matched, the fixed white list needs to be checked, and the specific situation can be set according to the actual situation, which is not limited herein.

The preferred embodiments of the present application will be described below with reference to the accompanying drawings of the specification, it should be understood that the preferred embodiments described herein are merely for illustrating and explaining the present application, and are not intended to limit the present application, and that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
Fig. 2 is a schematic flowchart of a white list-based vehicle passing method according to an embodiment of the present application. As shown in fig. 2, the method may include:
step S210, the terminal equipment identifies the license plate image of the current vehicle in the current lane acquired by the lane camera, acquires the license plate number, the camera identification and the image identification time, and sends the license plate number, the camera identification and the image identification time to a management server in communication connection with the terminal equipment.
In specific implementation, when a current vehicle enters a recognition range of a current lane, a lane camera collects a license plate image of the current vehicle and carries out image recognition to obtain a license plate number, image recognition time and the like in the license plate image. Since the lane camera is installed on the terminal device, the terminal device may acquire a camera identification (or "camera serial number") of the lane camera.
And the terminal equipment sends the license plate number and the camera identification to a management server in communication connection with the terminal equipment.
Step S220, the management server searches the stored lane information table and determines a target lane mark corresponding to the camera mark.
The lane information table is stored in the management server, and the lane information table may include area information of different lanes corresponding to different parking lot identifications, and corresponding relationships between lane identifications of corresponding different lanes and different camera identifications.
In specific implementation, the management server searches for a stored lane marker corresponding to a stored camera marker matched with the acquired camera marker in the lane information table, and determines the stored lane marker as a target lane marker corresponding to the acquired camera marker.
And step S230, the management server judges whether to send a barrier gate opening instruction to the terminal equipment or not based on the target lane identification, the license plate number and the image recognition time.
In specific implementation, the management server judges whether the current vehicle passes through the preset white list based on the target lane identification, the license plate number and the image recognition time, namely judges whether the current vehicle passes through the preset white list and meets the condition of any type of white list in various types of configured white lists, and judges whether the image recognition time is in the valid period of the white lists of various types; if yes, a barrier gate opening instruction is sent to the terminal equipment; if not, the vehicle is processed by adopting a conventional vehicle passing method.
Specifically, determining a detection sequence of each type of white list configured by a configuration server; sequentially searching whether a target lane mark and a license plate number exist in each type of white list according to the detection sequence, and whether the image recognition time is in the valid period of each type of white list; and if the target lane mark and the license plate number exist in any type of white list and the image recognition time is in the valid period of the white list of the type, determining that the current vehicle passes through the white list and meets the passing condition of the preset white list.
Each type of white list may include a fixed white list and a dynamic white list; the dynamic whitelist may include a billing free whitelist, a visitor whitelist, and a lane whitelist. The fixed white list comprises a first parking lot identifier, a first license plate number, a first lane identifier, a first camera identifier and the validity period of the parking card; the non-charging white list comprises a second parking lot identifier, a second license plate number, a second lane identifier, a second camera identifier, an access record identifier and a non-charging valid period; the visitor white list comprises a third parking lot mark, a third license plate number, a third lane mark, a third camera mark, a visitor mark and the start-stop time of the visitor entering the parking lot; the lane white list comprises a fourth parking lot mark, a fourth lane mark, a fourth camera mark and a lane type, wherein the lane type is an entrance and an opening type of all automatic opening.
It should be noted that the dynamic white list may further include a custom white list; taking the yard identity as an example, the specific yard identities in the first yard identity, the second yard identity, the third yard identity and the fourth yard identity may be the same or different, and the naming is different only in the category of the white list.
The fixed white list can only store related information such as license plate numbers of fixed monthly trucks, parking space cards, visitant cards and the like, the valid period of parking cards and the like. The validity period is generally set by the system and is longer. The dynamic white list can be used for generating license plate number lists of all parking lots in a specified range without charging according to the parking lot rules, setting a certain rule, calculating license plate number lists and visitor lists meeting requirements through calculation, and dynamically calculating result lists such as UI specified lists. Because most of the dynamic white lists are result data of dynamic calculation, the validity period of general data is within 1 hour or within the time range of the vehicle passing in and out, and the data is generally short.
Updating the fixed white list: the configuration server can update the parking card according to the validity period of the parking card in the fixed white list when the parking card reaches the validity end date, or the fixed white list needs to be updated after the parking card in the parking card registration database is updated.
Updating the dynamic white list: the configuration server can configure the configured white list updating data, such as lane marks as free or target license plate numbers as free, and update the dynamic white list at regular time (such as half an hour); or processing the obtained current vehicle access document input by the staff, such as calculation processing, to obtain new white list updating data, and updating the dynamic white list.
It should be noted that, the management server may configure the order or disable the partial whitelist type for the white list selection of the application.
Step S240, the terminal device forwards the barrier gate opening instruction to the barrier gate control unit to execute the rod raising operation, so that the current vehicle passes through.
In specific implementation, after receiving a barrier gate opening instruction sent by a management server, the terminal device forwards the barrier gate opening instruction to a barrier gate control unit to execute a rod lifting operation, so that a current vehicle passes through.
Further, after the management server sends a barrier gate opening instruction to the terminal equipment, a data service thread is opened, and the current passing data of the vehicle is stored in a cache; based on preset processing conditions, carrying out service data processing on the traffic data of the current vehicle; the traffic data processing may include recording of traffic data for the current vehicle and calculation of the associated traffic fare.
Specifically, after the traffic data of the current vehicle is stored in the cache, if the load of the management server is too high, the requirement of the current service (such as traffic charging service or traffic data recording service) can be acquired, and the traffic data of the current vehicle is stored in the relevant service processing queue according to the requirement of the current service, and when the load of the management server is redundant, the service processing is sequentially performed based on the processing sequence of the service processing queue. Or after the current vehicle passing data is stored in the cache, the current vehicle passing data is stored in a processing queue according to the vehicle passing time sequence, and the data in the processing queue is processed at regular time, wherein the specific processing flow is not limited herein.
Therefore, the embodiment of the application matches the lane identification and the license plate number through the white list, so that the vehicle passes firstly, namely, only the passing state is changed, and then the service calculation of the vehicle is carried out.
In some embodiments, the configuration server configures the fixed white list by:
step 11, obtaining the card type, the validity period and the corresponding parking lot identification of at least one parking card with the valid start date smaller than the current date and the valid end date larger than the current date in the stored parking card registration database;
step 12, inquiring a corresponding license plate information table based on the card number of at least one parking card to obtain a customer ID associated with the parking card and the license plate number of a first license plate number corresponding to the corresponding customer ID;
step 13, inquiring a corresponding private parking space table based on the client ID to obtain the parking space number corresponding to the client ID;
step 14, under the condition that the same parking lot identification and the same customer ID are checked, comparing the number of the vehicle license plates corresponding to any one of the same customer ID to obtain a first vehicle license plate number corresponding to a target customer ID with the number of the vehicle license plates larger than the number of the vehicle license plates and the validity period of the corresponding parking card;
step 15, inquiring a stored card sending information table of the parking card to obtain a first parking lot identification, a first license plate number, a first lane identification and a first camera identification corresponding to the first lane identification, wherein the first parking lot identification, the first license plate number, the first lane identification and the first camera identification correspond to the target customer ID;
and step 16, generating a fixed white list based on the first parking lot identifier, the first license plate number and the first camera identifier corresponding to the first lane identifier corresponding to the target customer ID and the validity period of the corresponding parking card.
It is understood that the fixed white list may further include information such as a card type of the parking card, a target customer ID, an authorization area identifier where the first lane identifier is located, and the like, in addition to the above information.
Based on the above embodiments, in some embodiments, after configuring the fixed white list, the configuration server establishes a communication connection with the lane camera to be loaded based on the current camera identifier of the lane camera to be loaded; and splicing the configured fixed white lists into communication data according to the communication protocol of the lane camera to be loaded, and sending the communication data to the lane camera to be loaded through communication connection. Wherein, the specific procedure steps may include:
and step 21, reading the white list stack table of the database, and acquiring a data list to be updated, wherein the state to be updated comprises three types of adding, modifying and deleting.
Step 22, generating a data set to be updated of each camera according to the camera identification, and executing the following steps for each camera in a circulating manner:
(1) Acquiring communication connection with a camera through a camera identifier;
(2) Generating an empty set of a database to be updated;
(3) Acquiring the first 5 pieces of data in a set to be updated, splicing the data into communication data (including a license plate number, a validity period, an update state identifier and the like) according to a camera communication protocol, and recording a data ID (identity);
(4) Calling a white list updating interface of the camera, and sending spliced communication data;
(5) Receiving a camera processing result;
(6) Removing the processed successful data from the data set to be updated of the camera according to the data ID, and adding the data ID recorded in the step (3) into an empty set to be updated of the database;
(7) Repeating the steps (3) to (6) until the update data set is completely updated;
(8) And updating the white list stack table of the database into an updated state according to the ID of the set to be updated of the database.
Further, when the terminal device detects that the terminal device is disconnected from the management server in communication, the terminal device determines whether the current vehicle passes through a fixed white list or not based on the current lane mark and the license plate number after acquiring the license plate number of the license plate image and the current camera mark of the lane camera to be loaded; if the current vehicle passes through the lifting rod, the barrier gate opening instruction is forwarded to the barrier gate control unit to execute the lifting rod operation.
In addition, the terminal device needs to cache the traffic data of the vehicles that are passing during the disconnection of the communication connection, and the terminal device data resends the cached traffic data to the management server after the communication connection between the terminal device and the management server is restored.
In some embodiments, if the current vehicle passes through the white list, the management server determines whether the time length between the image recognition time and the current time is greater than a preset time period;
if the current time is greater than the preset time, refusing to send a barrier gate opening instruction to the terminal equipment;
and if not, sending a barrier gate opening instruction to the terminal equipment.
In some embodiments, the process of configuring each white list in the dynamic white list by the configuration server may include:
(1) Charging white list is not required:
a, inquiring a vehicle access record table to obtain information such as license plate numbers, parking lot identifications, access time and parking areas of vehicles in a parking lot at present, access record data IDs corresponding to the license plate numbers and the like;
and step B, respectively inquiring a vehicle card state table and a charging record table based on the obtained license plate number, and obtaining information such as the acquired parking lot identification, the entrance and exit record data ID, the license plate number, the entrance time, the stop time, the card type, the stop area, the paid amount and the like by combining the data in the step A.
Step C, inquiring a parking lot charging standard table based on the parking lot identification and the card class, and acquiring information such as the charging standard specification of the parking area; the charging standard detail comprises the duration and the charging amount of each charging time interval in the charging; if the charging amount of the two time periods is consistent, combining the two time periods (charging duration is added, and the charging amount is unchanged);
