Description

Technical Field

[0001] The present invention relates to the field of blockchain technology, and more specifically, to a parking revenue information processing method based on blockchain. Background Art

[0002] In today's community life, parking issues are becoming increasingly important. Traditional parking lots use parking fee collection systems to manage vehicle entry and exit, record time and fees, and ultimately generate a data report for subsequent query and audit. However, this seemingly simple and direct management method has encountered many problems in actual operation.

[0003] Due to the limitations of the system design and various problems accumulated in long-term operation, traditional parking systems often lead to confusing reports and inconsistent data, which not only affects the smooth operation of the daily operation of the parking lot, but also provides security personnel with the possibility of abusing their power and using parking spaces for personal purposes. For the property management committee and property management personnel, due to the difficulty in reconciliation, it is difficult for them to accurately grasp the actual operation of the parking lot, and thus difficult to make effective supervision. This series of problems undoubtedly brings great challenges to the management of the parking lot.

[0004] Specifically, the problem bills in traditional parking systems are particularly prominent. These problem bills may be caused by system failures, human operational errors or malicious tampering, resulting in disordered data reports and failure to accurately reflect the actual revenue of the parking lot. Even worse, such disordered data reports may also lead to security personnel abusing their power to privately occupy parking spaces or reduce or waive fees, further exacerbating the chaos in parking lot management.

[0005] In the face of these problems, traditional solutions often rely on security personnel to manually intervene and adjust the parking fee collection system. However, this method is difficult to ensure the authenticity and accuracy of the collected data, and it is difficult to achieve fair, objective, comprehensive and efficient parking management.

[0006] With the continuous development of information technology, blockchain technology has provided new ideas and methods for parking management. Blockchain technology, with its decentralized, tamper-proof and highly transparent characteristics, provides a new solution for parking revenue information management.

[0007] In the field of logistics management, for example, blockchain technology has been widely used and achieved remarkable results. Blockchain can record logistics information and ensure that the entire process of goods from production to sales can be traced. Similarly, the application of blockchain technology in the field of parking revenue management also has broad development prospects and potential. Summary of the invention

[0045] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the invention and are not used to limit the invention.

[0046] The existing technology sets up a specific module in the background of the parking fee collection system, which is specifically used to collect problematic bills, and integrates a remote assistance system to deal with abnormal events at the entrance and exit, and supports voice call functions. In this process, the security guard needs to inform the property management committee, property management and other relevant personnel of the abnormal situation by voice, and confirm the disposal results. However, this method requires a lot of human and material resources in actual operation, and may face the dilemma that the auditors cannot handle it immediately due to various factors.

[0047] To this end, the present invention proposes a parking revenue information processing method based on blockchain technology. The method combines blockchain technology with parking data to form a community parking revenue management system based on blockchain, which effectively handles problem bills caused by parking amount issues and non-amount issues, thereby ensuring the accuracy and reliability of parking data throughout the life cycle.

[0048] Figure 1 A block-chain-based parking revenue information processing method according to an embodiment of the present invention is disclosed. Figure 1 As shown, the present invention proposes a parking revenue information processing method based on blockchain, comprising the following steps:

[0049] Step S1, using a recognition algorithm to process parking data and identify and obtain problematic bills;

[0050] Step S2: Uploading the problematic bill data to the blockchain;

[0051] Step S3: Based on the distributed nature of blockchain, multiple blockchain nodes handle problematic bills.

[0052] In order to optimize the management of community parking revenue, the present invention proposes a parking revenue information processing method based on blockchain technology, which combines blockchain technology with parking data, can support the autonomous identification and judgment of problem bills, and upload the problem bill data to the blockchain, thereby ensuring the data is tamper-proof and secure. In addition, the present invention also allows the property management committee and the property management party to verify and approve the problem bills. The property management committee, property management and other personnel can easily complete the processing of problem bills by themselves, thus forming a distributed, secure, transparent and privacy-oriented data management solution, which greatly improves the processing efficiency.

[0053] These steps will be described in detail below. It should be understood that within the scope of the present invention, the above-mentioned technical features of the present invention and the technical features specifically described below (such as embodiments) can be combined and related to each other to form a preferred technical solution.

[0054] Step S1: Use a recognition algorithm to process parking data and identify problematic bills.

[0055] First, implement the data collection phase. The parking fee collection system comprehensively collects parking data in the community, including the number of existing parking spaces, real-time parking space usage status, vehicle type classification, vehicle entry and exit records, specific parking duration and corresponding fee amount, and other detailed information.

[0056] Next, the detailed information of the parking bill is directly extracted through the parking fee collection system. In order to effectively eliminate the potential impact of problematic bills in the parking system on data accuracy, the present invention uses advanced recognition algorithms to process parking bill information. This recognition algorithm can use machine learning and big data analysis technology to conduct in-depth analysis and comparison of each item of parking bill information, thereby discovering possible anomalies or problems.

[0057] Once situations such as abnormal charging amounts, abnormal entry records, abnormal parking duration, abnormal license plate information, abnormal system matching, abnormal bill cancellation, and abnormal bill status that is not determined are identified, these bills will be automatically marked as problem bills.

[0058] It should be pointed out in particular that the problematic bill refers specifically to the parking bill generated under the above-mentioned abnormal circumstances, including but not limited to abnormal charging amount, abnormal entry, abnormal parking time, abnormal license plate, abnormal matching, invalidated abnormality and undetermined abnormality.

[0059] Finally, data cleaning and integration are performed. Through data processing methods, the collected parking data is comprehensively cleaned and integrated to eliminate invalid and erroneous data in problematic bills and ensure the availability, integrity and credibility of the data. At the same time, data from different sources are unified and integrated to build a comprehensive and accurate community parking data system.

[0060] Step S2: Uploading the problematic bill data to the blockchain;

[0061] For the parking data after cleaning and integration, the present invention makes full use of the decentralized characteristics of blockchain technology and the characteristics that its data cannot be tampered with to ensure the authenticity and reliability of the data.

[0062] This process uses the distributed accounting and storage mechanism of blockchain, and abandons centralized hardware or management agencies. After the problem bill data is uploaded to the blockchain network, each data block of the blockchain network contains key information such as parking data, vehicle information, parking time, parking location, etc. All nodes store the information of these data blocks, thus building a huge data network. In this blockchain network, the rights and obligations of any node are equal, and the data blocks in the blockchain network are jointly maintained by nodes with maintenance functions.

[0063] Each data block is equipped with a timestamp to record the time when the data was generated, which makes it easier to track the source of the data and verify its authenticity.

[0064] With the help of blockchain technology, data sharing and disclosure are realized, so that all relevant participants can obtain detailed data on community parking in real time. In addition, since blockchain technology adopts a distributed storage method, each user can only access and view his or her own parking data, but cannot obtain the private information of other users, and cannot modify the parking data without authorization. Therefore, this technology has a strong privacy protection function, which significantly enhances the security and privacy protection of data.

[0065] Figure 2 A schematic diagram of the chaining process of a problem bill in a business application service node according to an embodiment of the present invention is disclosed, such as Figure 2 As shown, the chain operation of the problem bill is usually performed on the business application service node. The chain process of the problem bill on the business application service node further includes:

[0066] Get information about problematic bills;

[0067] Perform corresponding processing operations based on the problematic bill information;

[0068] Based on the problematic bill data and / or the above processing results, an on-chain transaction processing request is generated and sent to the blockchain network to complete the entire on-chain process.

[0069] Among them, the business application service node is an important component of the blockchain network. As a bridge connecting business applications and the blockchain network, it is responsible for receiving, processing and transmitting problem billing information.

[0070] Figure 3 The following is a schematic diagram of the process of writing a problem bill into a blockchain according to an embodiment of the present invention. Figure 3 As shown in the figure, the process of writing the problematic bill into the blockchain further includes:

[0071] The blockchain network receives an on-chain transaction processing request from a business application service node, wherein the on-chain transaction processing request includes an on-chain transaction processing request for a problematic bill;

[0072] Write the problem bill information into the block as transaction data.

[0073] Blocks are the basic data unit in the blockchain network. They contain records of multiple transactions or transactions. Writing the problem bill information into a block means that it is permanently and tamper-proof stored in the blockchain. This step ensures the transparency and credibility of the problem bill, allowing all participants to view and verify the problem bill data at any time.

[0074] It is worth noting that the blockchain writing process also involves multiple complex mechanisms and technologies, such as consensus algorithms, encryption algorithms, distributed storage, etc. These mechanisms and technologies jointly ensure the security, stability and scalability of the blockchain network.

[0075] Step S3: Based on the distributed nature of blockchain, multiple blockchain nodes handle problematic bills.

[0076] The present invention is based on providing an asynchronous processing and auditing, efficient and convenient supervision tool. It adopts blockchain technology, can automatically detect and identify problem bills, and upload the problem bill data to the chain to ensure the accuracy of the data, so that stakeholders can collaborate on the blockchain platform to complete verification, reporting and approval operations, thereby greatly improving the transparency and accuracy of the problem bill processing process and realizing strict supervision of the entire process of parking bill data verification.

[0077] Figure 4 A flowchart of problem bill handling and review according to an embodiment of the present invention is disclosed, such as Figure 4As shown, there are multiple blockchain nodes, which serve as verification role nodes, multi-level review role nodes, and supervision role nodes respectively:

[0078] The verification role node verifies and supplements evidence on the problematic bill;

[0079] The multi-level review role node includes several nodes, each of which performs a multi-level review on the problematic bill data. If the review fails, the node returns to the verification role node for further verification and evidence supplementation.

[0080] The supervisory role node supervises the entire process of the verification role node and the multi-level review role node to ensure the fairness and transparency of the process.

[0081] The multi-level review role nodes may include but are not limited to: Figure 4 The first-instance role, the second-instance role, and more review role nodes that may be added as needed.

[0082] In actual applications, the verification role node is usually attended by security guards, while the multi-level review role node may be undertaken by property management, property owners' committee and other roles responsible for review, and the supervision role node is usually undertaken by neighborhood committees or other third-party organizations.

[0083] Through blockchain technology, the data of problematic bills is processed on the chain, ensuring that the data is fair and open during the process of verification and approval of problematic bills by the property management committee, property management, etc., thereby ensuring the openness, transparency and accuracy of parking data.

[0084] Taking a real-world scenario as an example, when some vehicles leave a parking lot, security guards will manually process these parking bills due to missing vehicle entry records or abnormal amounts, and charge actual parking fees accordingly. These bills that have been manually intervened are problematic bills in the parking fee collection system.

[0085] In order to achieve full-process supervision of problem bill processing, when a problem bill is generated, the security guard of the verification role node will automatically detect or accept manual reporting and appeal, and then the property management committee or property management staff of the multi-level review role node will review it separately. If the review fails, the security guard of the verification role node will be notified to submit more detailed verification and supplementary relevant evidence, and the property management committee or property management staff will review it again and finally form the review result.

[0086] The community parking revenue management method based on blockchain provided by the present invention automatically detects problematic bills through recognition algorithms, and writes problematic bill data into the blockchain using blockchain technology. The property management committee, property management and other relevant personnel can complete the verification and approval process by themselves, thereby simplifying the operation process, improving the accuracy of the data and reducing the difficulty of use.

[0087] Figure 5 A schematic diagram of a terminal device display process of a problematic bill according to an embodiment of the present invention is disclosed, such as Figure 5 As shown in the figure, after the problematic bill data is uploaded to the blockchain, the following operations are further performed:

[0088] The problem bill information is sent to the terminal device corresponding to the problem bill.

[0089] Once a problematic bill enters the blockchain block, it can be queried and displayed through a personal terminal, allowing users to instantly understand the disposal status of the problematic bill.

[0090] The specific steps are as follows:

[0091] receiving parking bill information for the vehicle;

[0092] When the parking bill conditions of a vehicle meet the criteria for determining a problem bill, problem bill information will be generated based on the parking bill of the vehicle and uploaded to the blockchain;

[0093] Subsequently, the problematic bill information will be sent to the personal terminal device of the community stakeholder corresponding to the parking bill information.

[0094] Through the above steps, the present invention ensures the openness, transparency and accuracy of the problematic bill data.

[0095] Although the above methods are illustrated and described as a series of actions for simplicity of explanation, it should be understood and appreciated that these methods are not limited by the order of the actions, because according to one or more embodiments, some actions may occur in a different order and / or concurrently with other actions from those illustrated and described herein or not illustrated and described herein but understandable to those skilled in the art.

As an example, executable instructions may be deployed to be executed on one electronic device, or on multiple electronic devices located at one location, or on multiple electronic devices distributed at multiple locations and interconnected by a communication network.
