AUSTRALIA Patents Act 1990
The following statement is a full description of this invention, including the best method of performing it known to me:
[0001] The disclosure relates to the technical field of parking space sharing, and particularly relates to a system and method for sharing parking space based on a blockchain.
[0002] Most of the existing systems for sharing parking spaces store data with a cloud platform, sense the states of parking spaces with various sensors, and control the opening or closing of parking locks. In the aspect of user management, there are users and system administrators. In the aspect of the parking space management, there are parking space smart locks, cloud platform storage and unified monitoring to ensure the security of the parking space information and the intelligent management of the parking spaces. In the aspect of sensors, considering usage scenarios and requirements, there are ultrasonic sensors, geomagnetic sensors and pressure sensors. For example, the Chinese patent application No. CN 106781689 A discloses a system for sharing parking space. The system uploads the parking space information to the cloud platform, and uses the cloud platform to manage the parking spaces, which not only meets the sharing needs of free parking spaces and the parking requirements of vehicle owners to make full use of the free parking spaces and obtain economic income, but also alleviates the difficulty in parking. The Chinese patent application No. CN 108039057 A discloses a system for sharing parking space and an implementation method. The system adopts a smart parking lock and a mobile terminal APP and is communicated with a parking space sharing cloud platform through Bluetooth, thereby realizing the intelligent management and facilitating the government regulation. The Chinese patent application No. CN 208000680 U discloses a system for sharing parking space. The system adopts a radio-frequency control technology to control a parking lock. A radio-frequency controller is connected with a cloud management platform through the Internet. The parking lock is indirectly controlled by the cloud management platform, thereby implementing the opening or closing of the parking lock.
[0003] However, these systems for sharing parking spaces only integrate the parking space information and issue the parking space information to the cloud platform, and the users are difficult to rapidly obtain the secure and reliable shared parking space information; and moreover, the parking spaces are in different locations, so that the parking spaces cannot be uniformly managed, and the use rate of the system for sharing parking space is difficult to increase.
[0004] The disclosure aims at providing a system and method for sharing parking space based on a blockchain, which is convenient for users to rapidly find shared parking spaces near a destination and capable of ensuring the safety and reliability of the sharing information of the parking spaces.
[0005] The technical solution for realizing the purpose of the disclosure is: the system for sharing parking space based on the blockchain includes an application layer, a server layer, a middleware layer and a data storage layer.
[0006] The application layer includes a web browser and a mobile phone client, the web browser is used for a parking space administrator to manage registered user information, parking space information, order information, announcement information and user information. The mobile phone client is used for a user to inquire the parking space information, check and change account information, issue the parking space information and evaluate the use of the parking space.
[0007] The server layer includes a data statistics module, a data processing module and a data query module, which are used for data statistics, processing and query.
[0008] The middleware layer includes a member management module, a Fabric SDK module and a chain code function module and is used for data exchange between the application layer and the blockchain.
[0009] The data storage layer includes a relational database and a state database and is used to provide a data storage space for the user information, parking space administrator information, the parking space information, the order information, notification announcements, push messages and member authentication information.
[0010] The web browser is established by a Bootstrap framework. The parking space administrator utilizes the web browser to inquire and maintain the basic information of the parking spaces in a jurisdiction range, inquire basic information of the user, historical records of the parking space shared and historical records of parking space used by the user, process complaint information submitted by the user, issue the announcement information, inquire historical announcement records and inquire transaction vouchers according to order ID.
[0011] The mobile phone client, based on an Android system, is configured for user registration and system login, searching the shared parking spaces within a destination range, displaying location information and an available time period of the parking space, checking and changing the basic information of the user, issuing and revoking the shared parking space information, scoring the order, acquiring credit scores, submitting the complaint information, and inquiring the historical order information, the push messages and the notification announcements.
[0012] Further, the data statistics module is used for the parking space administrator to perform the data statistics for the shared parking space information issued by the user, free parking space information, revoked shared parking space information, in-use parking space information, completed order information, registered user information and notification announcement information. The shared parking space information includes an issuer ID, parking space addresses, the available time period, issued order ID and issuing time. The free parking space information includes the issuer ID, the parking space addresses, the available time period and the issued order ID. The revoked shared parking space information includes the issuer ID, a revoker ID, the parking space addresses and revoking time. The in-use parking space information includes the issuer ID, lessee ID, the parking space addresses and a use time period. The completed order information includes the issuer ID, the lessee ID, the parking space addresses, the use time period, evaluation grades and leased order ID. The registered user information includes a user ID, a nickname, contact information, credit scores, a user state, issued shared parking space records, shared parking space usage records and an applause rate. The notification announcement information includes announcement IDs, announcement types, announcement titles, announcement content and issuing time.
[0013] The data processing module is used for data processing of the information issued by the parking space administrator and the user. The parking space administrator issues the notification announcement, pushes the notification announcement to the registered user, processes the user complaints, rewards and punishes complainants and respondents, handles the registered user, pushes warning messages to the user according to the credit scores and the applause rate of the user or freeze the user account. The user issues and revokes the parking space shared information, earns and deducts the credit scores and performs the grade evaluation for the lease experience of the parking spaces.
[0014] The data query module is used for data query of the information issued by the parking space administrator and the user. The parking space administrator inquires the transaction voucher information stored in the blockchain according to the issued order ID and the leased order ID, and inquires the issued shared parking space record, the leased parking space record and the applause rate of the user according to the user ID. The user inquires all parking space information within the destination range, inquires the basic information of the user, a parking space shared information issuing record, a parking space shared information revoking record, a completed order record and a submitted complaint record, and inquires specified notification announcements and push messages.
[0015] Further, the member management module is used for certificate authentication of the user and the parking space administrator, and utilizes a public key infrastructure PKI to issue digital certificates to the registered user and the parking space administrator. Only authenticated users and parking space administrators can access the order information stored in the blockchain.
[0016] The Fabric SDK module is used for the data exchange between external applications and the blockchain. When the order information is stored by the external applications, a data format of the order information is regulated at first; then the SDK is invoked; and a specified chain code function is called for data storage. When the external applications inquire the order information, whether the order ID is valid is judged at first; then the SDK is queried; and the specified chain code function is called for the data query.
[0017] The chain code function module is used for data access of the issued order and the leased order in the blockchain. When the order data is stored, a data format of the order information is regulated at first; then a data storage chain code function is called for data storage; and the transaction ID is returned. When the order data is acquired, a data query chain code function is called for data acquisition according to a specific transaction ID, and a query result is returned.
[0018] Further, the relational database is used to locally store the basic information of the user, the basic information of the parking space administrator, the notification announcements, the push messages and the parking space information.
[0019] The state database is used to store the authentication information of the user, issued order information of the shared parking space and order information of the leased parking space in the blockchain.
[0020] A method for sharing parking space based on a blockchain includes the following steps:
[0021] step 1, a user searches a shared parking space within a predetermined range of a destination through a mobile phone client, and a system judges the shared parking space according to a coordinate of the destination; if no parking space exists, the information of "no parking space near the destination" is returned, thereby failing to reserve the parking space; and if a parking space exists, the information of all parking spaces is returned, and step 2 is entered;
[0022] step 2, the user selects a specified parking space for reservation;
[0023] step 3, the system judges a state of the parking space; if the parking space is in use, the information that "the parking space is unavailable" is returned, thereby failing to reserve the parking space; and if a free parking space exists, step 4 is entered;
[0024] step 4, the system judges a credit score of the user; if the credit score is less than or equal to 0, the information of "insufficient credit score" is returned, and the reservation of the parking space fails; and if the credit score is greater than 0, the information that "the parking space is reserved successfully" is returned; the parking space is reserved successfully; and step 5 is entered;
[0025] step 5, when the user arrives at a destination parking space, a sensor sends an order verification request, and step 6 is entered;
[0026] step 6, the system judges whether the user reserves the parking space in the system; if the user does not reserve the parking space in the system, the information of "no reservation of the parking space" is returned, and the parking fails; and if the user already reserves the parking space in the system, the information of "success in verification" is returned, and the parking operation is carried out;
[0027] step 7, after the user stops the use of the parking space, the sensor sends an evaluation request, and the user performs the grade evaluation for the parking space;
[0028] step 8, the system judges the evaluation grade of the user; if the evaluation grade is less than 3, the credit score of a parking space issuer is deducted, and a negative comment message is pushed to the parking space issuer; and if the evaluation grade is greater than or equal to 3, the credit score is rewarded to the parking space issuer, and a positive comment message is pushed to the parking space issuer; and
[0029] step 9, the systemjudges the evaluation time of the current user; if the evaluation time is within a reservation time period, the credit score is rewarded to the user, and the information that "the order is completed normally and the evaluation is succeeded" is returned; and if the evaluation time is out of the reservation time period, the user credit score is deducted, and the information that "the order is completed overtime and the evaluation is succeeded" is returned.
[0030] Compared with the prior art, the disclosure has the significant advantages: (1) the vacancy rate ofurban parking spaces is reduced, and the problem of difficulty in parking in the city is alleviated; (2) by adopting the credit score bookkeeping, the use is convenient, and the charge escaping problem of the user is avoided; (3) the unified management is convenient for the user to use the shared parking space and convenient for the parking space administrator to manage the shared parking space; (4) the parking space information is secure and reliable, and attack behaviors of malicious users for sensitive data such as personal information of the user can be prevented; and (5) by adopting the authorization management, the parking space administrator and the user are provided with different permissions, so that the security and the convenience of the system can be improved.

[0084] step 2, the user selects a specified parking space for reservation;
[0085] step 3, the system judges a state of the parking space; if the parking space is in use, the information that "the parking space is unavailable" is returned, thereby failing to reserve the parking space; and if a free parking space exists, step 4 is entered;
[0086] step 4, the system judges a credit score of the user; if the credit score is less than or equal to 0, the information of "insufficient credit score" is returned, and the reservation of the parking space fails; and if the credit score is greater than 0, the information that "the parking space is reserved successfully" is returned; the parking space is reserved successfully; and step 5 is entered;
[0087] step 5, when the user arrives at a destination parking space, a sensor sends an order verification request, and step 6 is entered;
[0088] step 6, the system judges whether the user reserves the parking space in the system; if the user does not reserve the parking space in the system, the information of "no reservation of the parking space" is returned, and the parking fails; and if the user already reserves the parking space in the system, the information of "success in verification" is returned, and the parking operation is carried out;
[0089] step 7, after the user stops the use of the parking space, the sensor sends an evaluation request, and the user performs the grade evaluation for the parking space;
[0090] step 8, the system judges the evaluation grade of the user; if the evaluation grade is less than 3, the credit score of a parking space issuer is deducted, and a negative comment message is pushed to the parking space issuer; and if the evaluation grade is greater than or equal to 3, the credit score is rewarded to the parking space issuer, and a positive comment message is pushed to the parking space issuer; and
[0091] step 9, the system judges the evaluation time of the current user; if the evaluation time is within a reservation time period, the credit score is rewarded to the user, and the information that "the order is completed normally and the evaluation is succeeded" is returned; and if the evaluation time is out of the reservation time period, the user credit score is deducted, and the information that "the order is completed overtime and the evaluation is succeeded" is returned.
