[0002] Different terminals have different business characteristics and security levels. For example, some terminals require that only valid reservation codes can be used to enter the gate for operation, but some terminals have a higher security level and require that valid reservation codes bound to vehicle license plates can be used to enter the gate for operation.

[0056] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0057] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0058] In view of the defects mentioned in the background technology, the following requirements are summarized.

[0059] Improve gate entry efficiency: Under different tasks, the driver only needs to present a QR code. Both manual gates and smart gates can automatically determine whether the current vehicle includes a valid entry task by scanning the QR code.

[0060] Reduce the error rate in handling procedures: The QR code contains the information or key feature code of this appointment. After scanning and parsing the QR code, it is compared with the data in the system to determine whether it is valid, without the need for manual verification based on documents.

[0061] Adapt to multi-state needs: customize different reservation QR codes according to the reservation business characteristics and security levels of different terminals.

[0062] In an exemplary embodiment, Figure 1 As shown, a method for generating a vehicle reservation information QR code is provided, including the following steps 101 to 105.

[0063] Step 101, obtain vehicle reservation information; the vehicle reservation information includes: license plate number, trailer frame number, box number, reservation number, reservation validity deadline, operating time range, encoding and decoding mode, QR code validity deadline and verification level.

[0064] Step 102, splicing the license plate number, trailer frame number, box number, reservation number, reservation validity deadline, operable time range, QR code validity deadline and verification level in the vehicle reservation information to obtain spliced ​​data.

[0065] Step 103: Encode the spliced ​​data according to the encoding and decoding mode to obtain encoded data.

[0066] Step 104, adding a feature code number to the header of the encoded data to obtain the marked encoded data; the feature code number represents the encoding and decoding mode.

[0067] Step 105, converting the marked coded data into a QR code image.

[0068] By implementing the above steps 101 to 105, the compatibility of different entry reservation information in the vehicle reservation systems of different terminals is achieved, thereby improving the efficiency of vehicle entry and reducing errors.

[0069] In another exemplary embodiment of the present application, a pre-allocation strategy can be formulated based on the vehicle reservation information in the above step 101. In the subsequent application process, only specific information needs to be filled in according to the pre-allocation strategy.

[0070] The operating time range is as follows: different gate entry time ranges are set according to the business type. For example, containers can be picked up all day, non-special containers can be picked up from 09:00 to 16:00 every day, and special containers can be picked up from 09:00 to 12:00 every day.

[0071] The encoding and decoding modes include: base64 mode and key encryption and decryption mode. In base64 mode, the plain text information (i.e. concatenated data) is converted into base64 encoded information (i.e. encoded data). In key encryption and decryption mode, the plain text information is first encoded by Base64 and then encrypted by the DES algorithm into encrypted text. At this time, the encrypted text is the encoded data.

[0072] The validity period of a QR code includes two types: indefinite and valid for a certain period of time.

[0073] The verification level includes S-simple verification level and F-full data verification level. The simple verification level means that as long as the reservation code is valid, the QR code is within the validity period, and the reservation is within the validity period, the operation can be considered. In addition to the reservation number verified by the simple verification level, the full data verification level also needs to check whether the current vehicle license plate number and trailer frame number are consistent with the reservation information. If they are not consistent, the operation is not allowed; whether the box number carried this time is consistent with the box number planted in the reservation information, if they are not consistent, the operation is not allowed.

[0074] In another exemplary embodiment of the present application, in the above step 102, part of the information in the vehicle reservation information is spliced ​​together according to a fixed format. The fixed format is: #P-reservation number#T-license plate number#-C-trailer frame number#N-in-box number 1-in-box number 2#E-reservation effective deadline#W-operation start time-operation end time#Q-QR code effective deadline#K-verification level number#Z-anti-counterfeiting random code#. The anti-counterfeiting random code consists of 3 pure numbers and is regenerated each time preprocessing is performed.

[0075] In another exemplary embodiment of the present application, in the above step 103, if it is base64 mode, the preprocessed data (i.e., the spliced ​​data) is encoded into encoded data using base64; if it is key encryption and decryption mode, the preprocessed data (i.e., the spliced ​​data) is first base64-encoded to obtain the initial encoded data, and then the preset key is used to encrypt it again through the DES algorithm to obtain the encrypted encoded data.

[0076] In another exemplary embodiment of the present application, in the above step 104, a feature code number is added to the header of the encoded data, and the format of the marked encoded data is: feature code number encoded data, for example: FeEevr456FRx. There are two types of feature code numbers: B: base64 mode, F: key encryption and decryption mode.

[0077] In another exemplary embodiment of the present application, in the above step 105, a third-party QR code generation function or a locally integrated QR code generation library is used to convert the marked coded data into a QR code image.

[0078] Based on the same inventive concept, the embodiment of the present application also provides a vehicle reservation information two-dimensional code generation device for implementing the vehicle reservation information two-dimensional code generation method involved above. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in one or more vehicle reservation information two-dimensional code generation device embodiments provided below can refer to the limitations of the vehicle reservation information two-dimensional code generation method above, and will not be repeated here.

[0079] In an exemplary embodiment, a vehicle reservation information two-dimensional code generating device is provided, comprising:

[0080] The vehicle reservation information acquisition unit is used to obtain the vehicle reservation information; the vehicle reservation information includes: license plate number, trailer frame number, box number, reservation number, reservation validity deadline, operating time range, encoding and decoding mode, QR code validity deadline and verification level.

[0081] The vehicle reservation information preprocessing unit is used to splice the license plate number, trailer frame number, box number, reservation number, reservation validity deadline, operating time range, QR code validity deadline and verification level number in the vehicle reservation information to obtain spliced ​​data.

[0082] The encoding unit is used to encode the spliced ​​data according to the encoding and decoding mode to obtain encoded data.

[0083] The marking unit is used to add a feature code number to the header of the coded data to obtain the marked coded data; the feature code number represents the encoding and decoding mode.

[0084] The two-dimensional code generating unit is used to convert the marked coded data into a two-dimensional code image.

[0085] In an exemplary embodiment, a vehicle reservation information QR code parsing method corresponding to the above-mentioned vehicle reservation information QR code generation method is provided, such as Figure 2 As shown, the vehicle reservation information QR code parsing method includes the following steps 201 to 204.

[0086] Step 201, parse the QR code image to obtain a string of text; the QR code image is obtained by using the above-mentioned vehicle reservation information QR code generation method.

[0087] Step 202, identifying the feature code number and the data to be decoded in the character string text; the data to be decoded is the coded data in the above-mentioned vehicle reservation information two-dimensional code generation method.

[0088] Step 203: decode the data to be decoded according to the feature code number to obtain plaintext data.

[0089] Step 204: verify the plaintext data.

[0090] By executing the above steps 201 to 204, decoding can be performed according to different encoding and decoding modes and verification levels, thereby achieving compatibility of different entry reservation information in vehicle reservation systems of different terminals, improving vehicle entry efficiency, and reducing errors.

[0091] In an exemplary embodiment, in the above step 201, after obtaining the QR code image, a third-party QR code generation function or a locally integrated QR code generation library is used to parse the QR code image into a string text.

[0092] In an exemplary embodiment, in the above step 202, the feature code number and the data to be decoded in the parsed string text are identified; the parsed feature code number is converted into a string array using a space as a separator, such as ["F", "eEevr456FRx"], and then the feature code extraction method and the data to be decoded extraction method are used to extract the feature code and the data to be decoded respectively. Feature code extraction method: Get the 0th bit of the string array as the feature code. Data to be decoded acquisition method: Get the 1st bit of the string array as the data to be decoded.

[0093] In an exemplary embodiment, in the above step 203, the corresponding decoding method is called according to the identified feature code to parse the data to be decoded into decoded plaintext data. Decoding method: If it is S, it is decoded and returned by the base64 decoding algorithm. If it is F, it is first decrypted by the DES algorithm using the key, and then decoded and returned by the base64 decoding algorithm.

[0094] In an exemplary embodiment, in the above step 204, the verification method is called according to the decoded plaintext data to verify and return the verification result as available or unavailable. First, the reservation deadline, the workable time range and the validity period of the QR code in the plaintext data are verified. If all the verifications are successful, the corresponding verification method is called for verification according to the verification level. Verification method: If it is a simple verification, the reservation number in the plaintext data is compared with the matching reservation number status in the database. If it is not used, it returns available, otherwise it returns unavailable. If it is a full data verification, on the basis of the simple verification result being available, the external input operation vehicle information is compared with the decoded plaintext information. If all the comparisons are inconsistent, it returns unavailable. If they are consistent, it is further compared with the vehicle information corresponding to the reservation number in the database. If they are consistent, it returns available, otherwise it returns unavailable. Vehicle information includes: license plate number, trailer frame number, and box number.

[0095] It supports simple verification or full data verification mode, and the algorithm can be transplanted and embedded in OCR (optical character recognition) recognition equipment to achieve simple verification.

[0096] Based on the same inventive concept, the embodiment of the present application also provides a vehicle reservation information two-dimensional code parsing device for implementing the vehicle reservation information two-dimensional code parsing method involved above. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in one or more vehicle reservation information two-dimensional code parsing device embodiments provided below can refer to the limitations of the vehicle reservation information two-dimensional code parsing method above, and will not be repeated here.

[0097] In an exemplary embodiment, a vehicle reservation information two-dimensional code parsing device is provided, comprising:

[0098] The two-dimensional code parsing unit is used to parse the two-dimensional code image to obtain a character string text; the two-dimensional code image is obtained by using the above-mentioned vehicle reservation information two-dimensional code generation method.

[0100] The decoding unit is used to decode the data to be decoded according to the feature code number to obtain plain text data.

[0102] Based on the above method embodiments and device embodiments, the technical solution of the present application has the following technical effects.

[0103] 1. The reservation information is transmitted with a smaller amount of data or in an encrypted format.

[0104] 2. The appointment information is converted into a universal QR code format, which is no longer traditional plain text information. It does not require manual processing, which improves appointment efficiency.

[0105] 3. The strategy pattern can support rapid expansion of different requirements and improve reuse value.
