Description

Technical Field

[0001] The present application relates to the field of blockchain technology, and specifically to a blockchain-based rental equipment supply chain management method and execution system. Background Art

[0002] In the traditional supply chain management of rental equipment, there are many problems that affect the efficient operation and information management of the rental business. Although a variety of information technology means have been introduced to improve management efficiency and service quality, there are still many challenges and limitations. These problems are mainly reflected in the following aspects: First, in terms of information storage and management of rental equipment, information is usually stored in a centralized database, which brings data security risks. Since data is stored in a centralized manner, it is vulnerable to malicious attacks. Once the database is hacked, key information of the rental equipment, such as equipment status, rental information, user data, etc., may be tampered with or leaked, which will cause serious damage to the interests of the rental company and users. Moreover, data storage and updating in this centralized storage model often rely on a single information management system. System failure or maintenance may cause data unavailability, affecting the normal development of the rental business.

[0003] Secondly, in the management of the leasing cycle, the status monitoring and information update of the equipment are not timely and accurate enough. Traditional methods rely on manual inspection and record keeping, which is not only inefficient but also prone to human errors and information delays. For example, during the leasing period, the information such as the use status, physical location, and operating parameters of the equipment is not timely enough, making it difficult to monitor the use of the equipment in real time. When the equipment is abnormal, such as exceeding the normal working parameter range or physical damage, it cannot be detected quickly, resulting in untimely maintenance, affecting the service life of the leased equipment and the continuity of the leasing business.

[0004] Furthermore, there are many inconveniences in the settlement and status inspection process of leased equipment at the end of the lease period. The inspection of equipment when it is returned is usually done manually, lacking standardized and objective judgment criteria, which can easily lead to disputes. It is difficult to accurately assess whether the equipment is damaged or lost, especially for the inspection of external damage, which often lacks detailed and objective assessment basis, resulting in disputes between the lessor and the lessee over damage liability and compensation.

[0005] Fourth, the data generated during the leasing process is scattered in different places, making it difficult to form a complete record and chain of evidence. There is no unified storage and management mechanism for the initial status of the leased object, various information updates during the lease period, and the final status at the end of the lease. This makes it difficult to trace the details of the entire lease cycle when problems or disputes arise, which brings great difficulties to the handling of disputes in the leasing business.

[0006] Therefore, the traditional supply chain management method for leased equipment has many shortcomings in terms of information storage security, real-time and accuracy of lease cycle management, standardization of settlement and inspection at the end of the lease, integrity of the chain of evidence, and data support for business optimization, which seriously affects the efficiency, reliability and traceability of the leasing business.

[0024] Please refer to Figure 1 In order to solve the technical problems that the traditional leasing equipment supply chain management method has many deficiencies in information storage security, real-time and accuracy of leasing cycle management, settlement and inspection standardization at the end of the lease, evidence chain integrity, and data support for business optimization, which seriously affects the efficiency, reliability and traceability of the leasing business, a blockchain-based leasing equipment supply chain management method is provided in the embodiment of the present application, and the management method includes the following steps: Step S101: Establish a data model of the leased object; the data model of the leased object includes real-time status information of the leased object, and the data model of the leased object is stored on the blockchain.

[0025] In some embodiments, first, a data model of the leased object is established. This data model is a structured collection that comprehensively covers all types of information about the leased object, including the real-time status information of the leased object. This real-time status information may include but is not limited to the current physical location of the leased object, the operating parameters of the equipment (such as the temperature, operating speed, pressure, etc. of the equipment), the use status of the equipment (whether it is in use, idle or in maintenance), and the health status of the equipment (whether there are potential failure hazards). Subsequently, the data model is stored on the blockchain; the distributed storage and encryption characteristics of the blockchain ensure the security and immutability of the data model, so that the data of the leased object can be stored in a safe and reliable environment. The data model is jointly maintained by each node of the blockchain to ensure its consistency and traceability in the entire network, avoiding the risks of data loss and tampering that may be faced by traditional centralized storage, and providing a solid data foundation for subsequent leasing business operations.

[0026] For a rental cycle, follow the steps below: Step S102: Before the lease period starts, obtain the data model of the leased object from the blockchain as the initial state of the leased object.

[0027] In some embodiments, before the lease period begins, the data model of the leased object is obtained from the blockchain. Through the secure access mechanism provided by the blockchain, the data model of the corresponding leased object is accurately found and extracted; after obtaining the data model, it is used as the initial state of the leased object at the beginning of the current lease period. This initial state provides a reference basis for subsequent operations, for example, it can help the lessor and the lessee confirm the status of the leased object at the beginning of the lease, including the initial location of the equipment, initial performance indicators, etc.

[0028] In some embodiments, the acquired initial status data is checked to ensure its completeness and accuracy, providing a complete and reliable information basis for subsequent leasing business processes and avoiding subsequent problems caused by errors or omissions in the initial data.

[0029] Step S103: During the lease period, the status information of the leased object is monitored in real time by an IoT sensor, and the status information is updated to the data model of the leased object.

[0030] In some embodiments, the status information of the leased object is monitored in real time by IoT sensors deployed on the leased object. The IoT sensors can be diverse, for example, using GPS sensors to accurately track the location information of the leased object to ensure real-time updates of its location information; using temperature sensors to monitor the working temperature of the equipment in real time, and once the temperature exceeds the normal range, possible abnormalities can be detected in time; using accelerometers to monitor the vibration of the equipment to determine whether the equipment is in a stable operating state, etc. By continuously collecting data from such sensors and updating this status information to the data model of the leased object in a timely manner, each update is performed on the blockchain, and the reliability and consistency of the update operation are ensured by using the smart contract of the blockchain, so that the status information in the data model of the leased object is always in the latest state, thereby ensuring that all parties can grasp the latest status of the leased object in real time, overcoming the information delay and inaccuracy problems existing in traditional manual monitoring, ensuring the normal use and maintenance of the leased equipment, and ensuring the smooth progress of the leasing business.

[0031] Step S104: After the lease period ends, the device status is checked through the IoT sensor, the data model of the leased object is updated, and the record of the lease period is saved in the blockchain data model.

[0032] In some embodiments, when the lease period ends, the device status is comprehensively checked through IoT sensors. On the one hand, various IoT sensors will continue to be used, such as cameras or other scanning devices to check the appearance of the leased object to check whether there are surface scratches, dents, missing parts or color changes and other appearance damage; at the same time, other types of sensors are used to check the internal operation status of the device to ensure that the performance indicators of the device at the end of use meet expectations. For the device status information obtained from the inspection, it is updated to the data model of the leased object so that the data model fully records the final status of the leased object at the end of the lease period. In addition, the records of the entire lease period, including the lease start time, end time, rent payment, various events that occurred during the lease period (such as equipment maintenance, handling of abnormal situations, etc.) and the final device status information are stored in the blockchain data model; the data stored on the blockchain forms a complete chain of evidence, which is convenient for subsequent query and traceability. Whether it is the lessor, the lessee or the regulatory department, they can resolve possible disputes based on these tamper-proof data, and provide a reference basis for future leasing business, enhancing the reliability and traceability of the leasing business.

[0033] In the above-mentioned blockchain-based rental equipment supply chain management method, as a preferred solution, the data model of the leased item also includes the equipment ID of the leased item. The equipment ID is the coding information that uniquely identifies the leased item. When establishing the data model of the leased item, the equipment ID is stored on the blockchain together.

[0034] In some embodiments, when establishing a data model for a leased item, the device ID of the leased item must be included therein. The device ID, as the coding information that uniquely identifies the leased item, plays a vital role. It is like an identity tag for the leased item, which can accurately locate and identify the specific leased item among many leased devices. After the data model for the leased item is established, the device ID is stored on the blockchain. With the help of the characteristics of the blockchain, the security, immutability and traceability of the device ID information are guaranteed. In this way, no matter in which link of the leasing business, all information related to the leased item can be quickly and accurately obtained through the device ID, avoiding information confusion and mismatching, and laying a solid foundation for the efficient development of the leasing business.

[0035] In the above-mentioned blockchain-based rental equipment supply chain management method, as a preferred solution, before the start of the rental period, the data model of the leased item is obtained from the blockchain as the initial state of the leased item, and it also includes: verifying the integrity of the obtained initial state data, triggering a data supplement request if the data is incomplete, and obtaining the missing data from the backup data source to complete the construction of the initial state.

[0036] In some embodiments, before the start of the lease period, when obtaining the data model of the leased item from the blockchain as the initial state of the leased item, the integrity of the obtained initial state data needs to be verified; carefully check whether the data covers the key information of the leased item, such as the basic parameters of the equipment, initial location information, etc.; if the data is found to be incomplete, immediately trigger a data supplement request; according to pre-set rules and processes, accurately find and obtain the missing data from the backup data source; properly integrate the missing data obtained into the initial state data, thereby completing the construction of the initial state; through this series of operations, ensure that the initial state data based on the initial stage of the leasing business is complete and correct, provide reliable guarantees for the smooth progress of the subsequent leasing process, and reduce business risks and potential disputes caused by missing data.

[0037] In the above-mentioned blockchain-based rental equipment supply chain management method, as a preferred solution, during the rental period, the status information of the leased item is monitored in real time through an IoT sensor, including: real-time monitoring of the location information of the leased item through an IoT sensor, obtaining the location coordinate information of the leased item through a GPS sensor, and updating the location coordinate information as location status information to the data model of the leased item.

[0038] In some embodiments, during the lease period, when the status information of the leased item is monitored in real time through the IoT sensor, the location information of the leased item is monitored; the location coordinate information of the leased item is obtained with the help of a GPS sensor, and this information can accurately reflect the location of the leased item in geographic space; the obtained location coordinate information is timely updated to the data model of the leased item as location status information; during the update process, the data update specifications and protocols of the blockchain are followed to ensure that the location information is accurately stored on the blockchain; in this way, all parties to the lease can query the current location of the leased item at any time, which facilitates the allocation, management and security monitoring of the leased item, improves the visualization and management efficiency of the leasing business, and reduces the risk of loss or improper use of the leased item.

[0039] In some embodiments, during the lease period, the status information of the leased item is monitored in real time through IoT sensors, and the operating parameter information of the leased item is also monitored; the operating parameters of the leased item are obtained through various types of sensors such as accelerometers and temperature sensors; the accelerometer can capture the vibration of the equipment, and the temperature sensor can sense the temperature change of the equipment; when these operating parameters exceed the preset threshold range, an exception report is quickly generated; the exception report records in detail the time when the exception occurred, the specific values ​​of the abnormal parameters, and the possible impact range; the exception report is then updated to the data model of the leased item; according to the data storage and management mechanism of the blockchain, the abnormal information can be properly preserved; in this way, the operating anomalies of the leased item can be discovered in time, which facilitates timely maintenance measures to ensure the normal operation of the leased item and reduce business interruptions and losses caused by equipment failures.

[0040] In the above-mentioned blockchain-based rental equipment supply chain management method, as a preferred solution, during the rental period, the status information of the leased item is monitored in real time through an IoT sensor, and it also includes: real-time monitoring of the operating parameter information of the leased item through an IoT sensor, obtaining the operating parameters of the leased item through an accelerometer, a temperature sensor, etc. When the operating parameters exceed a preset threshold range, an abnormality report is generated and updated to the data model of the leased item.

[0041] In some embodiments, after the lease period ends, the device status is checked through the IoT sensor. First, after the lease period ends, the appearance of the leased item is scanned using the IoT sensor or scanning device. The scanning process needs to be comprehensive and detailed to ensure that all surfaces and key parts of the leased item are covered. The scanned appearance image or data of the leased item is compared with the pre-stored initial appearance image or standard appearance template of the leased item. When comparing, image recognition technology and data analysis algorithms are used to accurately determine whether there are differences in the appearance. The comparison results are analyzed to determine whether there is any appearance damage, where appearance damage includes surface scratches, dents and protrusions, missing parts and color changes. If damage is found in the appearance, the damage details such as the damage type, damage location and damage degree will be carefully recorded and updated to the data model of the leased item. If no damage is found in the appearance, the comparison is terminated. Through this standardized process, the appearance status of the leased item after the end of the lease period is objectively and accurately evaluated, providing a reliable basis for the leasing parties in the equipment return acceptance link, and reducing disputes caused by disputes over appearance status.

[0042] In the above-mentioned blockchain-based rental equipment supply chain management method, as a preferred solution, after the end of the rental period in step S104, checking the equipment status through the IoT sensor includes the following steps: Step S201: After the lease period ends, the appearance of the leased item is scanned by an IoT sensor or scanning device.

[0043] Step S202: Compare the scanned appearance image or data of the leased object with the pre-stored initial appearance image or standard appearance template of the leased object.

[0044] Step S203: Analyze the comparison results to determine whether there is any appearance damage: Step S204: If the appearance is found to be damaged, the damage details including the damage to the damaged appearance will be recorded and updated to the data model of the leased object.

[0045] Step S205: If no damage to the appearance is found, the comparison ends.

[0046] The appearance damage includes surface scratches, dents and bumps, missing parts and color changes; the damage details include damage type, damage location and damage extent.

[0047] In some embodiments, after the end of the lease period, the device status is checked through the IoT sensor. First, after the end of the lease period, the appearance of the leased item is scanned using the IoT sensor or scanning device. The scanning process must be comprehensive and detailed to ensure that all surfaces and key parts of the leased item are covered. The scanned appearance image or data of the leased item is compared with the pre-stored initial appearance image or standard appearance template of the leased item. When comparing, image recognition technology and data analysis algorithms are used to accurately determine whether there are differences in the appearance. The comparison results are analyzed to determine whether there is any damage to the appearance, where the appearance damage includes surface scratches, dents and bumps, missing parts and color changes. If damage is found in the appearance, the damage details such as the damage type, damage location and degree of damage will be carefully recorded and updated to the data model of the leased item. If no damage is found in the appearance, the comparison is terminated. Through this standardized process, the appearance status of the leased item after the end of the lease period is objectively and accurately evaluated, providing a reliable basis for the leasing parties in the equipment return acceptance link, and reducing disputes caused by disputes over the appearance status.

[0048] In the above-mentioned blockchain-based rental equipment supply chain management method, as a preferred solution, during the rental period of step S103, after the step of monitoring the status information of the leased object in real time through the IoT sensor and updating the status information to the data model of the leased object, the following steps are also included: Step S301: extract key information based on the updated data model, in accordance with the predetermined report template and data screening rules, wherein the key information includes but is not limited to the location, operating status, usage time, and abnormal events of the device.

[0049] Step S302: Generate a leased property status report using the extracted key information.

[0050] Step S303: Store the generated leased property status report on the blockchain and set corresponding access rights, where the access rights are used to ensure that the lease parties can view the leased property status report according to their respective rights.

[0051] In some embodiments, during the lease period, after the status information of the leased item is monitored in real time through IoT sensors and the status information is updated to the data model of the leased item, key information needs to be extracted according to the updated data model, in accordance with predetermined report templates and data screening rules; key information includes but is not limited to the location, operating status, usage time, and abnormal events of the equipment; these key information are accurately screened out from the data model, and data analysis and integration technology are used to generate a leased item status report using the extracted key information; the report content should be clear and the format should be standardized; the generated leased item status report is stored on the blockchain, and corresponding access rights are set; access rights are set based on the roles and business needs of the two parties to the lease to ensure that the two parties to the lease can view the leased item status report according to their respective permissions; in this way, the two parties to the lease can promptly understand the details of the leased item during the lease period, promote information transparency and smooth communication of the lease business, and improve the quality of lease services and customer satisfaction.
