Description

System and method for management of collective building}

The present invention relates to the management of aggregates, and more particularly, to an aggregate management system and method that can collect and manage expenses and perform expenses and audits of aggregated buildings using blockchain networks and smart contracts.

In the present invention, the aggregate building is a concept including not only a building set consisting of a plurality of buildings, but also a building. The building includes a plurality of independent spaces that can be used by a plurality of tenants, but includes one or more buildings managed by one management institution. it means.

In general, the management of aggregated buildings consists of simple and environmental hygiene management and supply of manpower required for cleaning, while measuring and controlling the electricity supply, charging, collecting, and paying the bills. have. Since the 1990s, technology has been rapidly developed, and even though the machinery and the automation system of the assembly building are being advanced, the professional and systematic management and operation of the collective building has not been provided.

The management of the facilities of an assembly building is an important factor in determining the life span of a building, and it is also the key to determine the activation of the assembly and the value of the assembly through the convenience and efficiency of using the building and facilities. Although the individual owners or merchant tenants share and pay the administrative expenses, it is nevertheless social and economic that the lack of systematic and professional management services reduces the value of each relevant aggregate and reduces the life of the building. The loss is large.

On the other hand, since the management group is composed of at least tens to thousands of distinctive owners, the aggregated management related to the aggregates is gathered through numerous discussions and discussions on issues arising from time to time. It is a long way from resolving various conflicts and disputes.

For that reason, the Collective Building Management Act was enacted for each aggregated building to appoint and entrust the trustees or custodians to decide and enact the aggregated building management regulations and to manage the aggregated buildings through the appointed station or custodian.

However, due to the fact that there are not many commissioners and trustees or managers who have professional management capabilities, the social costs are increasing due to the increasing number of disputes and lawsuits related to the collective buildings due to the illicit and illegal method of management of the collective buildings. On the other hand, the commission, trust office, or manager are often involved in business duties or embezzlement, which also causes considerable economic damage to the members of the assembly building.

In addition, electric safety management, fire safety management, elevator safety management, parking lot safety management, security management, financial accounting, cleaning environment and hygiene management, generator / machinery / computerization, etc. To manage professionally in various areas such as general management of buildings, sufficient management personnel and resources are required.However, the excessive management cost share of the renters of buildings is a major cause of the vacancy of the buildings. The increase has the effect of reducing the cost of building management, which eventually leads to a vicious cycle of poorly managed and managed buildings.

The management and maintenance of the buildings and various facilities constituting each aggregate building are also important, but the selection of a company for professional maintenance and maintenance of each building and facilities, and the professional diagnosis and Appointment of building safety managers who regularly perform safety inspection, etc., Arrangement and appointment of many products and services suppliers for each building and facility, and supply of integrated management and operation services for construction orders and contract management. It is not enough.

The present invention is to solve the problems of the prior art as described above, the aggregated building management system that can collect the administrative costs of the assembly building using the blockchain technology, and can perform the expense and audit for various defect repair services and It is to provide a method.

In order to achieve the above object, the aggregate management system according to an embodiment of the present invention, acts as a node of a blockchain network and generates a transaction in the blockchain network to execute a smart contract for managing the aggregate building. An assembly building management server; A management station terminal having a cryptocurrency wallet for receiving a management fee of an assembly building and transmitting details of management expenses of tenants to the assembly building management server; Holds a cryptocurrency wallet for payment of the management fee requested from the assembly building management server that received the management fee details, receives an audit request for defect repair service and the audit result for the audit request according to the tenant's input And a tenant terminal transmitting to the building management server, wherein the assembly building management server pays an audit fee to the tenant who responded to the audit request when a predetermined audit requirement specified in the smart contract for the repair service is satisfied. To control the blockchain network.

When the predetermined audit requirement is satisfied, the assembly building management server may control to sell and cash the predetermined amount of cryptocurrency from the cryptocurrency wallet of the station terminal and transfer the cashed service fee to the worker's account.

The aggregate building management server further generates a cryptocurrency corresponding to a predetermined ratio of the mined amount when mining the cryptocurrency by the nodes of the blockchain network, and responds to the audit request with the additionally generated cryptocurrency. One tenant can be controlled to make a debit transfer to the cryptocurrency wallet.

According to an embodiment of the present invention, an aggregate building management method executed in a blockchain network includes: generating a transaction in the blockchain network to execute a smart contract for managing the aggregate building by operating as a node of the blockchain network; Requesting, by the building management server, the management fee payment to the tenant terminal when receiving the management fee details of the tenants from the management terminal; Controlling an amount corresponding to a management fee to be transferred from the cryptocurrency wallet of the tenant terminal to the cryptocurrency wallet of the station terminal; Transmitting an audit request for a defect repair service to the tenant terminal according to a request of the station terminal, and receiving an audit result for the audit request from the tenant terminal; If the predetermined audit requirements specified in the smart contract for the repair service is satisfied, controlling the blockchain network to pay the audit fee to the tenant responding to the audit request.

According to the present invention, the blockchain network is used to generate and distribute data related to the management of the aggregated building in blocks, and to perform the work-related and auditing actions in the management of the aggregated building according to the pre-defined smart contracts in a stepwise manner.

1 is a view for explaining the configuration of a collective building management system operating in a blockchain network according to an embodiment of the present invention.

Referring to FIG. 1, the aggregate management system operates as a node of a blockchain network to which a plurality of nodes 10, 15, 16, and 17 are connected to generate a transaction to execute a smart contract created to manage the aggregate. It includes a collective building management server 10 that provides a collective building management service, a series of terminals 20 used by the manager, members (residents) of each of the collective building, the worker of the repair service, etc. It may be implemented in the form of receiving a service by accessing (10).

In the present invention, the aggregate building is one or more buildings including a plurality of houses or stores owned or occupied by a plurality of subjects, and there exists a management institution managing the same. For example, this includes a multi-store complex including malls operated by a plurality of tenants, an apartment house such as an apartment or a villa, and an officetel.

The terminals 20 are computing devices such as a personal computer, a smart phone, a personal digital assistant (PDA), a portable computer, and the like, which have a predetermined communication means and communicate with the assembly management server 10 through a network. The terminals 20 may include a dedicated application that accesses the assembly management server 10 to use the assembly management service to be described later, and may settle or receive various expenses. Users may access the assembly building management server 10 to subscribe to the service, and at this time, a user type among an administrator, a tenant, and a worker may be selected and joined.

When the administrator subscribes to the service provided by the assembly building management server 10 through the terminal 11, he or she can register himself as a management authority and be pre-assigned the desired number of tenant IDs so that the occupants of the assembly can join. have. Residents will be able to receive their ID from the administrator and join with the ID.

In the aggregated building management system according to the present invention, cryptocurrency can be used for administrative expenses such as imposition and collection of each occupant, management expenses such as the cost of defect repair service, audit expenses, and the cryptocurrency is mined on the blockchain network. It is a virtual currency. In the present invention, the cryptocurrency may be used jointly in a plurality of aggregates provided by the aggregate management system to provide a management service, and a management institution, a tenant, and / or a worker purchase cash at an exchange and send it to their cryptocurrency wallet. Can be.

In an embodiment of the present invention, by using a cryptocurrency without price fluctuation, it is possible to provide an aggregate management service that can stably enjoy the advantages of a blockchain network without price volatility.

The aggregate management server 10 is a computing device that performs an intermediary role between the blockchain network and each of the user terminals 20. The aggregate management server 10 generates a smart contract on the blockchain network for managing the aggregate building, and then executes the smart contract. Holds its own cryptocurrency wallet as a node for generating transactions for execution of.

The smart contract may be defined through the terminal 11 used by the management agency of each assembly building and will include different contract contents according to the characteristics of the assembly building. The various functions constituting the aggregate management service and the conditions for executing the aggregate management service are included in the smart contract and recorded in the block of the blockchain network, and later, the aggregate management server 10 operates according to the smart contract to be customized to each aggregate building. Provide management services.

The blockchain network stores the smart contract and its associated cryptocurrency transactions in blocks (trade ledgers) for the aggregated building management service, and maintains them by determining whether they are forged through agreement of each node, that is, hash value calculation. do.

The aggregate building management server 10, which is a node of the blockchain network, sends a push message such as an administrative fee charge or an audit request to a dedicated application of the station terminal 11 or the tenant terminal 12 according to the smart contract, and the corresponding terminal 11, According to the response sent by 12), a transaction for executing a smart contract is generated on the blockchain network.

The management terminal 11 used in the management institution of the collective building (e.g., the management office of the complex shopping mall, the management office of the apartment, the management office of the officetel, etc.) constitutes a blockchain network that holds a cryptocurrency wallet for receiving the management fee. Subject. The station terminal 11 generates the management fee details to be charged to the occupants of the building periodically (eg, at the end of each month) according to the input of the manager and transmits them to the building management server 10. The cryptocurrency wallet of the station terminal 11 is for receiving the management fee of the assembly building from the tenants, and the cryptocurrency wallet can pay the costs for various defect repair services.

The assembly building management server 10 receiving the management fee details from the station terminal 11 transmits a management fee payment request to the terminal 12 of each tenant registered in the assembly building. The tenant terminal 12 is a constituent of a blockchain network which is a terminal of tenants who have entered the set building and holds a cryptocurrency wallet for payment of administrative expenses. The tenant may have an audit authority and input the audit result through his / her terminal 12 after the audit for the repair service for the assembly building.

The tenant terminal 12 outputs the management fee payment from the assembly building management server 10 so that the tenant knows it. If the tenant does not confirm the payment request or reject the payment for a predetermined period, the tenant's cryptocurrency wallet The management fee will be transferred to the cryptocurrency wallet of the station terminal 11. Such cryptocurrency transfers may also be performed by smart contracts that are generated in advance and stored in blocks.

In addition, when the tenant terminal 12 receives the audit request for the defect repair service from the assembly building management server 10, the tenant terminal 12 outputs the audit request to the tenant, and the audit result of the audit request according to the tenant's input is collected. Transfer to the management server 10. The station terminal 11 may receive and output data on an audit result of tenants through the assembly building management server 10. In addition, when the predetermined audit requirement specified in the smart contract for the repair service is satisfied, the assembly building management server 10 may control the blockchain network to pay the audit fee to the tenant who responded to the audit request.

In order to operate as a node of a blockchain network, it is necessary to continuously download and synchronize block data. The terminal 20 of the users does not directly store blockchain data having a large capacity, but acts as a kind of server 10. ) To use the aggregated building management service according to the present invention. The smart contract created by the user through his terminal 20 is included in the block by the assembly building management server 10, which is a node, and connected to the block chain.

Each node in the blockchain network is a mining entity that checks whether the transaction is forged by calculating the hash value of the entire book in Merkle Tree and receives a transaction fee in return. In other words, each node mines the block to which the ledger of the layer is added and adds it to the blockchain.

Aggregate building management server 10 may hold the name and ID, cryptocurrency wallet address of the aggregate building manager, tenants, workers that are customers. In addition, since each node stores the entire transaction ledger, the assembly building management server 10 may also grasp the details of the management of the aggregates, such as the management fee collection, the administration expenses, and the audit performance, directly from the blockchain network.

2 is a diagram illustrating a process of connecting a block including a smart contract to an existing blockchain according to an embodiment of the present invention.

As shown in FIG. 2, the terminal 20 of a general user such as an administrator or a tenant does not directly store blockchain data, but connects to a node 10 that acts as a kind of server, and thereby connects to the blockchain 23. Approach and use the smart contract 24. The terminal of the user 20 may access the blockchain network 22 using a remote procedure call through a web browser or a predetermined connection service. The smart contract 24 generated by the user on the network is recorded in a block so that the corresponding code is copied to other nodes so that the smart contract can be executed in the virtual machine 21 of each node 10.

The node 10 of the blockchain network is a server participating in the blockchain network, and has a synchronized blockchain data 23 because it plays a role of propagating the information when a block is generated. That is, the assembly building management server 10 is a node of the blockchain network 22 and also serves to connect the blockchain by allowing the general user 20 to access it.

In the present invention, the transaction is handled by the smart contract. In other words, since the transaction conditions are recorded in the block from the beginning, there are no operators, and if the conditions are satisfied, regardless of what transactions or actions are made in the world, the management of the aggregate building and the transactions of the cryptocurrency will be performed as determined by the smart contract. It happens automatically and authenticity is guaranteed by agreement of each node. At least one smart contract is created and a corresponding smart contract object is created and distributed for a series of transactions related to the management of the aggregate and thus the movement of cryptocurrency. The distribution of smart contracts involves the inclusion of smart contract objects in blocks and the inclusion of them in the blockchain through mining. The smart contract according to the present invention controls the transaction to occur automatically when each condition is satisfied.

3 to 6 are flowcharts illustrating a method for managing a building according to various embodiments of the present disclosure.

Referring to Figure 3, the aggregate building management method according to an embodiment of the present invention may be composed of management fee management step for each occupant (S31), defect repair service management step (S32) and audit fee payment management step (S33). . Detailed description of each step will be described with reference to FIGS. 4 to 6.

Figure 4 is a flow chart for explaining the management fee management for each building occupant according to an embodiment of the present invention.

In step S41, the station terminal 11 calculates and charges a management fee for each occupant of the corresponding collective building. In order to charge the management fee, the station terminal 11 notifies each tenant of the management fee to the assembly building management server 10 and sends a smart contract to receive the storage fee to be recorded in a block on the blockchain network and transmits the management cost details for each tenant. Accordingly, the assembly building management server 10 transmits a message requesting payment of the management fee to the tenant terminal 12 of the assembly.

If the tenant who checks the management fee details in the terminal 12 selects the payment button or does not select the payment rejection within a predetermined period, in step S42 the management fee from the cryptocurrency wallet of the tenant terminal 12 to the cryptocurrency wallet of the station terminal 11. The amount corresponding to will be automatically transferred. Transactions for management fee transfer are also executed by smart contracts for management fee management

As such, the management fee, which is paid every month or at another predetermined period, is stored in the cryptocurrency wallet of the station terminal 11 and will be expended for certain items according to the smart contract for managing the management cost.

Figure 5 is a flow chart for explaining the management of the defective building repair service according to an embodiment of the present invention.

In step S51, a smart contract is generated for the repair service. When the manager of the building determines the contents of the smart contract through the management terminal 11 and sends it to the building management server 10, the smart contract is managed by the building management server 10, which is a node of the blockchain network. Will be generated. In this case, the contents of the smart contract may include information on the audit requirements such as the service amount, the location information of the renovation work, how many of the tenants need to be audited (check the work results), the cryptocurrency wallet address of the station, and the account information of the station. have.

In step S52, upon completion of the defect repair service, an audit is requested to the tenant terminal. When the administrator who confirms that the repair work has been completed selects the completion of the repair service in the dedicated application of the station terminal 11, the assembly building management server 10 sends an audit request message to the terminals 12 of the tenants according to the smart contract. send.

When the station staff manually determines whether the repair service is completed, the subsequent steps can be controlled by clicking the completion button. In case of automatically determining the completion by using the artificial intelligence system that analyzes the image collected by the camera photographing the renovation site, the next step such as audit will be performed automatically when the repair is completed.

The request for the audit will be sent to all or some of the tenants of the assembly according to the smart contract. For example, an audit request message is sent to a predetermined number of tenants, or an audit request message is provided to tenants who are located within a predetermined distance from the site when the repair work is completed by using the GPS (Global Positioning System) information of the tenant terminal 12. Or by the smart contract to send an audit request message to some tenants involved in the renovation.

The dedicated application of the tenant terminal 12 receiving the audit request will display a button asking whether to participate in the audit together with information on the defect repair work, and the tenant who confirms the result of the repair work presses a confirmation button to confirm the repair work result. You can either make a positive reply or press the reject button to make a negative reply indicating that the renovation was not done properly.

In step S53, the assembly building management server 10 collects a reply to the audit request from the tenant terminal 12, and determines whether the audit requirements specified in the smart contract have been met. The smart contract will specify whether the audit requirements are met when more than one or several percent of the tenants send positive audit results, and whether the audit requirements are met when more than one or several percent tenants send negative results. .

If the audit requirement is satisfied, it is determined that the audit is completed and the flow proceeds to step S55. In step S55, the cost for the defect repair service is paid from the cryptocurrency wallet of the station terminal 11. Defect repair costs can be paid in either cryptocurrency or cash.

In the embodiment of payment by cryptocurrency, the amount specified in the smart contract will be transferred from the cryptocurrency wallet of the station terminal 11 to the cryptocurrency wallet of the worker terminal 13.

In the embodiment to be settled in cash, in step S55, a predetermined amount corresponding to the defect repair cost specified in the smart contract is cashed out from the cryptocurrency wallet of the management terminal 11. It is impossible for the staff of the station to withdraw money from the cryptocurrency wallet before it is cashed by the smart contract, and only the expenses approved by the tenants' audit are cashed, so that illegal use such as embezzlement is impossible and transparent and reliable are guaranteed. Cost management becomes possible.

The cashed defect repair cost is transferred to the worker (service company) by the staff of the station or controlled so that the defect repaired cost that is cashed through the financial computer network is transferred from the station account to the worker's account (step S56).

If the audit requirement is not satisfied in step S53, the flow advances to step S54 to wait until the audit is completed or there is additional work by the manager. When the audit requirement specified in the smart contract is satisfied and the audit is completed, the process proceeds to step S55. You can do this if you have additional work, such as resending the audit request message or asking the other tenants for an audit.

6 is a flowchart illustrating an audit fee payment management according to an embodiment of the present invention.

The assembly building management server 10 controls the blockchain network to pay the audit fee to the tenant who responded to the audit request when the predetermined audit requirement specified in the smart contract for the defect repair service is satisfied.

Nodes in the blockchain network mine cryptocurrencies. When the nodes calculate the hash value and the cryptocurrency is mined, there is a buffer in which the cryptocurrency can be increased by a predetermined ratio. In step S61, the cryptocurrency of the cryptocurrency mined at the time of mining the cryptocurrency is additionally generated. For example, if five cryptocurrencies were mined in one hour and paid to each miner's cryptocurrency wallet, an additional one would be generated. The additional cryptocurrency generated is paid as a reward for the audit.

To this end, in step S62, a list of occupants who participated in the audit for a specific repair service is obtained. As the assembly management server 10 receives the audit result from the tenant terminal 12, it may identify which tenants participated in the audit for a predetermined period of time and generate a list of tenants who participated in the audit.

 In step S63, the additionally generated cryptocurrency is distributed and paid to the tenants included in the tenant list participating in the audit. Cryptocurrency additionally generated by mining cryptocurrency for a certain period may be divided into cryptocurrency wallets of tenants who participated in the audit during that period, and payment of such audit fees is also automatically performed by smart contracts.

In one embodiment, if some of the tenants who participated in the audit refuse to receive the cost, the execution of the smart contract may be delayed. In such a case, a dispute settlement process will be performed offline, and if all participants are satisfied, the deferred smart contract will be executed by the rejected tenants or the user (s) on their behalf.

Method according to an embodiment of the present invention is implemented in the form of program instructions that can be executed by various computer means may be recorded on a computer readable medium. The computer readable medium may include program instructions, data files, data structures, etc. alone or in combination.
