Description

Technical Field

[0001] The present invention relates to the technical field of blockchain data processing, and specifically to an intelligent cloud management method and system for rental housing based on blockchain. Background Technique

[0002] The intelligent cloud management of rental housing based on blockchain is an innovative method that combines cloud computing and big data analysis on the basis of blockchain technology to achieve efficient, secure, and intelligent management of rental housing. Specifically, through the decentralized characteristics of blockchain, the security and immutability of data are ensured, and at the same time, smart contracts are used to automatically execute lease agreements, reducing human intervention and errors.

[0003] After retrieval, the Chinese invention patent with the publication number "CN114548688A" discloses "a method for encoding management of a supply chain platform". The material encoding provided by this application can realize the material tracking of materials, without the need for the platform to perform additional tracking, and can also characterize the logistics service quality of the materials, serving as a good evaluation index for the average logistics after-sales of the demand side (consumers).

[0004] In addition, the Chinese invention patent with the publication number "CN11315962A" discloses "a visual, intelligent, and decentralized task allocation method and system". By adopting a decentralized task allocation algorithm, this application greatly improves fairness and accuracy, records and calculates the workload of each task and the time of each node, and any node and transaction can be traced. The work efficiency and load level of the entire board room can be statistically analyzed, providing great convenience for management.

[0005] However, in the actual operation process, the above two disclosed methods and similar methods still have deficiencies in data security and privacy protection. Especially when dealing with a large amount of sensitive information such as household data, it is difficult to ensure the absolute security of the data. Therefore, this application proposes an intelligent cloud management method and system for rental housing based on blockchain to solve the above existing problems. Summary of the Invention

[0006] The purpose of the present invention is to provide an intelligent cloud management method and system for rental housing based on blockchain to solve the problems raised in the above background technique.

[0007] In the first aspect, an intelligent cloud management method for rental housing based on blockchain is proposed, including: configuring a corresponding number of data control nodes according to the number of units in the rental housing, and each data control node is responsible for collecting and storing the household data and unit room data of the corresponding rental unit. All data control nodes together constitute a blockchain network;

[0008] Record the household data of each rental unit in real time within a unit time. The household data includes: personal information of the household, check-in date, and expected check-out date;

[0009] Once the household data of a rental unit changes, the data control node will capture the change in the household data and integrate the unit room data of the rental unit sequence at the changed position into a block trigger suffix;

[0010] Based on the generation of the block trigger suffix, the data control node will organize and update the unit room data in the corresponding unit sequence;

[0011] Through time series analysis, compare the differences in the unit room data of the corresponding unit sequence;

[0012] Generate a difference report according to the characteristics of the difference result;

[0013] Send the difference report to the household control terminal and the cloud service platform respectively through the blockchain network;

[0014] The household control terminal sends an adjustment instruction to the cloud service platform according to the difference report;

[0015] After verifying the adjustment instruction, the cloud service platform adjusts the unit room data of the corresponding unit sequence.

[0016] As a further optimization of this technical solution, construct an intelligent contract protocol, and the data control node, household control terminal, and cloud service platform realize data interaction based on the intelligent contract protocol;

[0017] The intelligent contract protocol stipulates the data exchange and operation processes among the data control node, household control terminal, and cloud service platform in the time dimension and geographical location dimension;

[0018] Based on the time dimension, set a time limit interval to restrict the interaction between the household control terminal and the data control node within the time limit interval;

[0019] Based on the geographical location dimension, delimit an activity range to restrict the interaction between the household control terminal and the data control node within the activity range.

[0020] As a further optimization of this technical solution, the time limit interval is several unit times after the block trigger suffix is determined, and the time limit interval is between the check-in date and the expected check-out date;

[0021] The data control node grants the household control terminal a time-limited control permission according to the household data, and the time-limited control permission is only valid within the time limit interval;

[0022] If the household control terminal does not respond or does not send an adjustment instruction to the cloud service platform within the time limit interval;

[0023] The data control node will automatically send the difference report to the cloud service platform;

[0024] The cloud service platform will retrieve the unit room data in the corresponding rental unit before the tenant moves in and use it as the basis for adjustment.

[0025] As a further optimization of this technical solution, a location-based association protocol is constructed, and the association protocol connects the units in the rental housing with the tenant control terminal;

[0026] Using the association protocol, determine the activity range of the tenant control terminal;

[0027] Once the tenant control terminal exceeds the established activity range, the data control node will suspend the timeliness control authority of the tenant control terminal and send a reminder of exceeding the range to the tenant control terminal;

[0028] In addition, the data control node will send the difference report to the cloud service platform for temporary takeover.

[0029] As a further optimization of this technical solution, when the tenant control terminal exceeds the preset activity range, the data control node records the length of time that the tenant control terminal loses the effective control authority;

[0030] If the tenant control terminal fails to return to the established activity range within the time limit, the cloud service platform will retrieve the tenant data in the corresponding rental unit before the tenant moves in and use it as the basis for adjustment to predict the tenant's return time;

[0031] Based on the predicted return time, optimize the control strategy of the unit room data and cut off the connection between the blockchain network and the tenant control terminal.

[0032] As a further optimization of this technical solution, the updated rental unit data will be entered into the corresponding data control node and updated in real time;

[0033] After receiving the updated rental unit data, the data node sends a confirmation control link to the tenant control terminal;

[0034] The tenant control terminal updates or stops changing the tenant data according to the confirmation control link;

[0035] According to the changes in the tenant data, adjust the interconnection channel between the tenant control terminal and the blockchain network.

[0036] As a further optimization of this technical solution, a real-time updated holiday information database is embedded in the data control node. The holiday information database is updated synchronously through the Internet. The holiday information database includes the name, specific date, type, and duration of the holiday;

[0037] Obtain a timestamp generated based on the check-in date and the expected check-out date;

[0038] Match the timestamp of the household data with the dates in the holiday information database;

[0039] Based on the matching result, analyze the linear relationship between the rental unit data and the holidays;

[0040] According to the result of the linear relationship analysis, enter the coefficient of the impact of holidays on the unit room data within the data control node as a reference standard for adjusting the unit room data;

[0041] During holidays, the data control node adjusts the control strategy of the unit room data according to the impact coefficient.

[0042] In a second aspect, to further improve the above technical solution, the present invention also proposes an intelligent rental housing cloud management system based on blockchain. It should be noted that an intelligent rental housing cloud management system based on blockchain uses the above-mentioned intelligent rental housing management method based on blockchain and includes:

[0043] A data control node cluster for constructing a blockchain network, collecting and storing the household data and unit room data of rental units;

[0044] A terminal control program for being installed in the user's mobile device. After the user's mobile device installs the terminal control program, it forms a user control terminal. The mobile device is connected to the data control node cluster through the blockchain network based on the terminal control program and is used to receive a difference report and send an adjustment instruction to the cloud service platform;

[0045] A cloud service platform, connected to the data control node cluster and the household control terminal through the blockchain network, for verifying the adjustment instruction and adjusting the unit room data according to the difference report and the adjustment instruction of the household control terminal;

[0046] An intelligent contract protocol module for specifying the data exchange and operation process between the data control node, the household control terminal, and the cloud service platform;

[0047] A geographical location association protocol module for constructing a geographical location-based association protocol, determining the activity range of the household control terminal, and restricting the interaction between the household control terminal and the data control node within the activity range;

[0048] A holiday information database module for storing and updating holiday information, providing the coefficient of the impact of holidays on the unit room data for the data control node as a reference standard for adjusting the unit room data.

[0049] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0050] The intelligent cloud management method and system for rental housing based on blockchain introduce blockchain technology to achieve decentralized storage and immutability of data, effectively improving the security and privacy protection level of data. At the same time, by using the smart contract protocol, the automation and intelligence of data exchange and operation processes are realized, improving the management efficiency to a certain extent. In addition, the present invention further restricts the interaction between the household control terminal and the data control node by setting a time limit interval and defining an activity range, further enhancing the security of data.

[0051] It should also be noted that the present invention constructs an association protocol based on geographical location. By determining the activity range of the household control terminal, effective control of the household control terminal is achieved. Once the household control terminal exceeds the established activity range, the data control node will suspend its time-limited control authority, send a reminder of exceeding the range, and be temporarily taken over by the cloud service platform to ensure the continuity and security of data.

[0052] It should also be supplemented that during holidays, the present invention analyzes the linear relationship between rental housing unit data and holidays through a real-time updated holiday information database, and adjusts the control strategy of unit room data according to the analysis results, further improving the intelligent level of management.

[0058] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present invention belong to the protection scope of the present invention.

[0059] Before delving into the innovative technical solution proposed in this application, it is necessary to clarify that before the technical solution involved in the present invention is actually put into operation, it is necessary to configure a corresponding number of data control nodes according to the number of each unit in the rental housing. Each data control node is responsible for collecting and storing the household data and unit room data of the corresponding rental unit. These data control nodes cooperate with each other to jointly form a complete blockchain network. In addition, it should be specifically supplemented that in the process of putting these data control nodes into actual use, they are specifically intelligent terminal devices in the prior art field, such as intelligent routers and intelligent gateways. Intelligent terminal devices not only have the ability to collect and store data, but also can interact with the cloud server through the built-in communication module to achieve real-time upload and synchronization of data.

[0060] As Figure 1 and Figure 2 shown, the present invention provides a technical solution: an intelligent rental housing cloud management method based on blockchain, which includes: step S100 - step S800.

[0061] Step S100: Real-time record the household data of each rental housing unit within a unit time.

[0062] It should be noted that in step S100, the household data includes: the personal information of the household, the move-in date, and the expected move-out date.

[0063] It should be supplemented that in the technical solution proposed in the present invention, step S100 is collected and recorded in real time by each data control node. Each data control node corresponds to a rental housing unit to ensure the accuracy and real-time nature of the data.

[0064] Step S200: Once the household data of the rental housing unit changes, the data control node will capture the change in the household data and integrate the unit room data of the rental housing unit sequence at the changed position to trigger a suffix.

[0065] It should be noted that in the technical solution proposed in the present invention, when it is detected that the household data changes, such as the move-in or move-out of a household, the data control node will immediately capture this change. Specifically, by comparing the current household data with the previously recorded household data, the changed part is identified. Subsequently, the data control node will integrate the sequence information of the rental housing unit related to this change, including the unit room data.

[0066] It should be added that in the process of integrated processing, the unit room data of the rental housing unit sequence at the changed position is spliced together before and after to form a complete block. Immediately afterwards, the data control node will add a trigger suffix to this block. The function of this trigger suffix is to identify that this block is ready to be added to the blockchain network for subsequent verification and storage. Through such a design, the present invention can ensure that changes in household data are captured in a timely and accurate manner and processed in the blockchain network in an efficient manner.

[0067] It should be noted that the trigger suffix and the block together form the block trigger suffix.

[0068] Step S300: Based on the generation of the block trigger suffix, the data control node will sort out and update the unit room data in the corresponding unit sequence.

[0069] It should be noted that in the present invention, step S300 is used to ensure that the data stored in the blockchain network is always up-to-date and can reflect the current actual situation of the rental housing unit.

[0070] Specifically, once the block trigger suffix is generated, the data control node will send it to the blockchain network for subsequent verification and storage. In this process, other data control nodes will receive this block trigger suffix and verify the unit room data therein to ensure the accuracy and integrity of the data. If the verification passes, this block trigger suffix will be added to the blockchain network and become a part of the blockchain. At the same time, the unit room data related to this block trigger suffix will also be updated to the blockchain network to ensure the timeliness and consistency of the data. Through such a design, the present invention can ensure that the data of the rental housing unit is updated in a timely and accurate manner and managed and maintained in the blockchain network in an efficient manner.

[0071] Step S400: Through time series analysis, compare the differences in the unit room data of the corresponding unit sequence.

[0072] It should be noted that in step S400, through time series analysis, the numerical differences in the unit room data at each time point are compared to identify the usage patterns and trends of the rental housing unit. It should be added that such analysis helps the rental housing manager better understand the behavior habits of the residents, predict future demand changes, and optimize the management strategy of the rental housing.

[0073] Specifically, time series analysis can include periodic analysis, trend analysis, and seasonal analysis of the data. Through these analyses, the manager can obtain the periodic rules of resident check-in and check-out, the long-term trend of the unit room occupancy rate, and the impact of seasonal factors on the rental housing market, so as to provide a basis for management decisions.

[0074] Step S500: Generate a difference report based on the characteristics of the difference result.

[0075] It should be noted that the method for generating the difference report in step S500 is to summarize and refine the difference results after time series analysis, capture the difference information and characteristics, and then compile these information and characteristics into a clear and understandable report through the table program of the existing computer. The content of the difference report covers the specific values of the differences. In this way, a set of intuitive and detailed data analysis tools can be provided for the rental housing managers to help them more comprehensively master the usage status of the rental housing units, identify potential problems in a timely manner, and take effective management countermeasures.

[0076] Step S600: Send the difference report to the household control terminal and the cloud service platform respectively through the blockchain network.

[0077] It should be noted that step S600 is used to achieve real-time sharing and synchronization of information in the present invention.

[0078] Specifically, once the difference report is generated, the data control node will send the difference report to the household control terminal and the cloud service platform through the blockchain network. The household control terminal, such as a smart phone or a tablet computer, can receive the difference report related to itself in real time, enabling the household to timely understand their housing conditions and possible problems. At the same time, the cloud service platform can also receive the difference reports of all rental housing units, providing a global perspective for the rental housing managers to help them better manage and maintain the rental housing. Through such a design, the present invention not only improves the transparency of information, but also strengthens the communication and interaction between the households and the managers, jointly promoting the intelligentization and high efficiency of rental housing management.

[0079] Step S700: The household control terminal sends an adjustment instruction to the cloud service platform according to the difference report.

[0080] It should be noted that in step S700, the adjustment instruction is generated by an instruction generation program in an existing computer. According to the difference data in the difference report, the corresponding adjustment instruction is generated automatically or semi-automatically. For example, if the difference report shows that the occupancy rate of a rental housing unit is continuously low, then the household control terminal will generate an instruction to adjust the rent or upgrade the housing facilities to attract more tenants. After the adjustment instruction is generated, the household control terminal will send it to the cloud service platform through the blockchain network and wait for the review and execution of the rental housing manager. Through such a design, the present invention gives households more participation rights and control rights, enabling them to put forward specific suggestions and measures for the management of rental housing according to their actual situations and needs. At the same time, it also provides a more flexible and responsive management means for the rental housing manager, jointly promoting the intelligent and personalized development of rental housing management.

[0081] Step S800: After verifying the adjustment instruction, the cloud service platform adjusts the unit room data of the corresponding unit sequence.

[0082] It should be noted that in step S800, the cloud service platform verifies the adjustment instruction by comparing the adjustment instruction with the difference report obtained by itself. Specifically, during the actual operation process, the cloud service platform checks the content of the adjustment instruction one by one to ensure that it is consistent with the information in the difference report without deviation or contradiction. Such a verification process is to ensure the scientificity and accuracy of management decisions and avoid management chaos or resource waste caused by incorrect information or instructions. Once the adjustment instruction passes the verification, the cloud service platform will adjust the unit room data of the corresponding unit sequence according to the specific requirements of the adjustment instruction. For example, adjusting the rent price, updating the housing facility information, or modifying the occupancy status of the household. After the adjustment is completed, the cloud service platform will resynchronize the updated unit room data to the blockchain network to ensure the real-time and consistency of all data. Through such a design, not only the intelligent and efficient management of rental housing is realized, but also the accuracy and scientificity of management decisions are improved, providing strong support for the healthy development of the rental housing market.

[0083] As a preferred embodiment, in this embodiment, an intelligent contract protocol is constructed by standardizing the data interaction process among the data control node, the household control terminal, and the cloud service platform.

[0084] Specifically, the intelligent contract protocol stipulates the detailed rules of the data exchange and operation process among the data control node, the household control terminal, and the cloud service platform in the time dimension and geographical location dimension, ensuring the accuracy and security of data interaction.

[0085] Reference Figure 3, in the time dimension, a time limit interval is set, and a time dimension mechanism is set. The time dimension mechanism ensures that the household control terminal only interacts with the data management and control node within the time limit interval. This approach improves the efficiency and security of data access permission management to a certain extent because it restricts data access and operations to a specific time range.

[0086] More specifically, the time limit interval is set based on a number of unit times after the block trigger suffix is determined. The number of unit times is between the household's check-in date and the expected check-out date, ensuring that the timeliness of the permission matches the actual residence time of the household. In addition, the data management and control node assigns corresponding timeliness control permissions to the household control terminal according to the household's data information. It should be added that these timeliness control permissions are strictly limited to use within the time limit interval. Once this time window passes, the permissions will automatically expire. If the household control terminal does not make any response or send any adjustment instructions to the cloud service platform within the time limit interval, the data management and control node will send a difference report to the cloud service platform. The cloud service platform will then retrieve the unit room data in the corresponding rental unit before the household checks in and use it as the basis for adjustment to ensure that the room settings and configurations can be adjusted according to the household's personalized needs.

[0087] Reference Figure 4 As can be seen, in the geographical space dimension, an activity area is planned, and through the geographical space dimension mechanism, it is ensured that the household control terminal can only interact with the data management and control node within this established activity area, significantly enhancing the security during the data interaction process and effectively preventing the risk of data leakage or unauthorized access.

[0088] More specifically, by constructing a geospatial association protocol, the association protocol connects each unit in the rental house with the household control terminal. Through this association protocol, the activity area of the household control terminal can be determined. Once the household control terminal attempts to exceed this established activity area, the data management and control node will immediately take action, terminate its timeliness control permissions, and send a warning prompt for exceeding the range to the household control terminal. At the same time, the data management and control node will send a report on this difference situation to the cloud service platform, and the cloud service platform will temporarily take over the control permissions to ensure the safe operation of the system.

[0089] In addition, during the actual operation of the smart contract protocol in the geospatial dimension, when the household control terminal exceeds the preset activity area, the data control node will record in detail the specific duration of time when the household control terminal loses effective control authority. If the household control terminal fails to return to the established activity area within the established time limit, the cloud service platform will retrieve the historical data of the corresponding rental housing unit before the household's occupancy. These data will be used as the basis for adjustment to help predict the household's return time. Based on this predicted return time, the cloud service platform will optimize the control strategy of the unit room data to adapt to the household's return pattern. For example, if the predicted return time indicates that the household may not be able to return for a long time, the cloud service platform will automatically adjust the energy usage strategy in the rental housing, such as reducing power supply or turning off unnecessary electrical equipment, to save energy. At the same time, the cloud service platform will also intelligently adjust the environmental settings in the room, such as temperature, humidity, and lighting, according to the household's living habits and preferences in the historical data to maintain the best state of the room during the household's absence. If the household's return time exceeds the expectation, the cloud service platform will also send a reminder message to the household through the household control terminal or other communication methods, advising the household to return as soon as possible or take corresponding measures to ensure the safety and normal management of the rental housing.

[0090] Finally, to further enhance security, the cloud service platform will cut off the connection between the blockchain network and the household control terminal until the household re-enters the established activity area, ensuring the security of the entire system and the integrity of the data.

[0091] In a preferred implementation manner, after receiving and verifying the adjustment instruction, the cloud service platform will make necessary adjustments to the unit room data in the specified unit sequence. Once these data adjustments are completed, the updated rental unit data will be promptly recorded in the corresponding data control node and will be immediately updated in real-time. When the data control node receives these updated rental unit data, the data control node will send a confirmation control link to the household control terminal. The household control terminal will use this confirmation control link to update the household's data or stop the data change when necessary. According to the change of the household's data, the household control terminal will correspondingly adjust the interconnection channel with the blockchain network to ensure data synchronization and security.

[0092] In a preferred implementation manner, in order to deeply explore the correlation between the rental housing and holidays, this implementation manner adopts an innovative method.

[0093] Specifically, by embedding a holiday information database that is updated in real time within the data control node, the holiday information database can be synchronized and updated via the Internet. This holiday information database details information including the name of the holiday, the specific date, the type, and the duration of the holiday. By obtaining the timestamps generated based on the check-in date and the expected check-out date, the timestamps of the household data are precisely matched with the dates in the holiday information database. Based on the matching results, the linear relationship between the rental unit data and the holidays is analyzed. For example, during holidays, whether the occupancy rate of the rental unit increases, or during certain specific holidays such as the Spring Festival and National Day and other long holidays, whether the reservation situation of the rental is more in short supply. At the same time, the impact of holidays on the rental price can also be analyzed. For example, during holidays, whether the rental price will increase, and whether this price increase trend is related to factors such as the type of holiday and the duration of the holiday. Through this method, we can understand more deeply the impact of holidays on the rental market, so as to provide more accurate predictions and suggestions for landlords and tenants, helping them better plan the use and reservation of rental housing. In addition, this kind of analysis also helps landlords and tenants better understand the market trend, so as to make more informed decisions.

[0094] According to the analysis results of this linear relationship, the coefficients of the impact of holidays on the unit room data are entered into the data control node as an important reference standard for adjusting the unit room data. During holidays, the data control node dynamically adjusts the control strategy of the unit room data based on these impact coefficients to ensure the flexibility and adaptability of the rental housing management.

[0095] Specifically, when the household data obtained shows a significant increase in the reservation volume during holidays, the data control node can automatically adjust the price strategy and appropriately increase the rental price to reflect the change in market demand. On the contrary, if the reservation volume decreases during holidays, the data control node can lower the price to attract more tenants. This dynamic adjustment not only helps landlords maximize their income but also ensures that tenants can obtain reasonable accommodation prices during holidays. In addition, the data control node can also formulate more refined control strategies according to factors such as the type of holiday and the duration of the holiday to meet the needs of different tenants. For example, during long holidays, the data control node can give priority to recommending rental units with complete facilities and convenient locations to meet the needs of family outings or long-distance trips; while during short holidays, it can recommend more cost-effective units to attract tenants for short trips or business trips. Through this intelligent management method, the rental housing market will become more efficient, flexible, and user-friendly.

[0096] In addition, referring to Figure 5It can be seen that the present invention further discloses an intelligent rental housing cloud management system based on blockchain technology. It should be particularly emphasized that an intelligent rental housing cloud management system based on blockchain technology adopts the previously mentioned intelligent rental housing cloud management method based on blockchain technology, and it consists of the following key parts:

[0097] The data control node cluster is responsible for establishing a blockchain network, and its main task is to collect and store the household data and unit room data of rental housing units;

[0098] The terminal control program is used to be installed on the user's mobile device. Once the terminal control program is installed, the user's mobile device is transformed into a user control terminal. The user control terminal can connect to the data control node cluster through the blockchain network by using the terminal control program and has the function of receiving difference reports. At the same time, it can also send adjustment instructions to the cloud service platform;

[0099] The cloud service platform. The user control terminal, the data control node cluster, and the household control terminal are connected through the blockchain network. The main responsibility of the cloud service platform is to verify the adjustment instructions sent by the household control terminal and make corresponding adjustments to the unit room data according to the difference reports and the adjustment instructions of the household control terminal;

[0100] The smart contract protocol module. The role of the smart contract protocol module is to stipulate the process of data exchange and operation among the data control node, the household control terminal, and the cloud service platform to ensure the efficient and secure operation of the entire system;

[0101] The geographical location association protocol module. The function of the geographical location association protocol module is to construct a geographical location-based association protocol. It can determine the activity range of the household control terminal and restrict the household control terminal to interact with the data control node only within the activity range, thereby enhancing the security and reliability of the system;

[0102] The holiday information database module. The holiday information database module is responsible for storing and updating holiday information, providing the coefficient of the impact of holidays on unit room data to the data control node as a reference standard for adjusting unit room data, and ensuring that the system can make appropriate adjustments to meet the needs of households during special periods such as holidays.

[0103] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.

The time-limited control authority is limited to use within the time limit. If the resident control terminal does not respond within the time limit or does not send an adjustment instruction to the cloud service platform; The data control node will automatically send the difference report to the cloud service platform; The cloud-based service platform will retrieve the unit data of the corresponding rental unit before the resident moves in and use it as the basis for the adjustment.

4. According to claim 2, a blockchain-based intelligent rental housing cloud management method is characterized by: Build a location-based association protocol that connects units in rental housing to resident control terminals; Using the association protocol, determine the activity range of the resident control terminal; Once the resident control terminal exceeds the established activity range, the data control node will terminate the time-effectiveness control authority of the resident control terminal and send a reminder of out-of-range to the resident control terminal; In addition, the data control node will send the difference report to the cloud service platform, which will temporarily take over.

5. According to claim 4, a blockchain-based intelligent rental housing cloud management method is characterized by: When the resident control terminal exceeds the preset activity range, the data control node records the length of time the resident control terminal loses effective control authority; If the resident control terminal fails to return to the established activity range within the time limit, the cloud service platform will retrieve the resident data in the corresponding rental unit before the resident moves in, and use it as the basis for adjustment to predict the resident's return time; Based on the predicted return time, the control strategy of the unit data is optimized, and the connection between the blockchain network and the resident control terminal is cut off.

6. According to claim 1, a blockchain-based intelligent rental housing cloud management method is characterized by: The updated rental unit data will be entered into the corresponding data management and control nodes and updated in real time; After receiving the updated rental unit data, the data node sends a confirmation control link to the resident control terminal; The resident control terminal updates or stops changing the resident data based on the confirmed control link; Adjust the interconnection channel between the resident control terminal and the blockchain network according to changes in resident data.

7. According to claim 1, a blockchain-based intelligent rental housing cloud management method is characterized by: A real-time holiday information database is embedded in the data control node. The holiday information database is updated synchronously through the Internet. The holiday information database contains the name, specific date, type and duration of the holiday. Get the timestamp generated based on the check-in date and expected check-out date; Match the timestamps of household data with dates in the holiday information database; Based on the matching results, the linear relationship between rental housing unit data and holidays is analyzed; According to the results of linear relationship analysis, the coefficient of the impact of holidays on unit data is entered in the data control node as a reference standard for adjusting unit data; During holidays, the data control node adjusts the control strategy of unit room data based on the impact coefficient.
