Figure 3f shows an example of a setting screen, when the settlement is made to the landlord's mobile notification or rent payment account information, the card information for paying the fee for use of the door lock system is displayed.

In the main screen of FIG. 3A, the Realors item is for inputting and managing real estate broker information, and may provide a function of easily linking an empty rental to the broker using the real estate broker information.

On the other hand, the renter management function in such a website may be provided through a mobile renter management application. For example, when the landlord registers, the landlord's information and the information of the land are registered, the door lock 10 is installed in the rental building, and the landlord's management application is downloaded and installed through the management server 40. The management application installs an encryption key for opening the door lock 10 in the tenant's user terminal 20. The landlord's encryption key is the same as or different from the tenant's encryption key.The landlord's encryption key can only be used temporarily if the tenant is not registered or if the tenant does not make a normal payment for a certain period of time. It should not be used for less than a delinquency period. In addition, information such as rent, renter, rent payment can be easily confirmed or managed through the rental citation management application.

Then, if the landlord and the tenant's contract for the lease is made or already made, the landlord enters and registers the tenant information in the management application or the website of the management server (40). The tenant may download and install the tenant's key management application through a web page or app store operating on the management server 40, and the management server 40 may open the door lock 10 installed at the door of the rental building to the tenant. Generate and issue encryption key information for tenants.

As described above, the method of installing the encryption key information on the user terminal 20 of the first tenant may be installed through the homepage or the key management application of the management server 40, but in some cases, the user terminal 20 of the landlord. It can also be installed through interworking with. The renter management application includes a tenant encryption key installation function through which the tenant's encryption key can be installed in the tenant's user terminal 20. Such a function is convenient and useful because the user can install the encryption key even if the payment is made at the date and time, such as a hotel, without having to download the management program.

On the other hand, the management server 40 according to the present invention can provide an open API to automatically post articles on the tenant, tenant's friends, family's access log records on their Twitter, Facebook, blog, etc., billing records as well You can provide an API to log.

The door lock system according to the second embodiment of the present invention will be described later. Descriptions of components similar to those of the first embodiment described above will be omitted.

In the first embodiment of the present invention, if the payment is not made for a certain period of time, the encryption key installed in the user terminal 20 is stopped and discarded so that the encryption key is not transmitted to the door lock 10 so as not to open the door. In contrast, the door lock system according to the second embodiment of the present invention includes the use period information in the encryption key information, so that it is possible to determine whether the door lock 10 is valid.

That is, the encryption key information stored in the user terminal 20 includes the encryption key and the period of use information that can open the door lock 10, and after the period of use, the corresponding encryption key is automatically disabled in the user terminal 20 or It may be discarded or not operated by disallowing the use of the encryption key that has expired in the door lock 10. For example, the door lock 10 may receive encryption key information (encryption key + usage period information) transmitted from the user terminal 20, and determine whether to open whether or not the encryption key is correct and whether the usage period is valid. If the encryption key information includes the period of use information, since the encryption key is installed in the first door lock 10 and the encryption key installed in the door lock 10 afterwards, the encryption key information of the user terminal 20 is settled. Although the period of use information is updated as it is made, the encryption key information installed in the door lock 10 may be convenient for management because it does not have to be updated.

In addition, in the above-described first embodiment, the key management application is executed every time the door lock 10 is opened to activate the encryption key in association with the management server 40. However, in the second embodiment, the period information is included in the encryption key information. Since there is no need to interlock with the management server 40 every time the door lock 10 is opened. That is, when the key management application is executed, the encryption key information is activated and transmitted to the door lock 10, and the door lock 10 determines validity by checking the period of use information included in the encryption key information. Therefore, if payment is made on a monthly basis, the encryption key information may be updated every month. For example, if the payment date is 20 days and the delinquency allowance period is 3 months, when the payment is made on January 20, the encryption key usage period is set to April 20, and the corresponding management password is applied to the key management application in the management server 40. Update key information. In addition, the door lock 10 has been legally issued during a certain period of use, so that the door lock 10 can be opened by the corresponding encryption key freely during the period, and furthermore, the keypad of the keypad of the door lock 10 can be opened. You can also provide a function to register and use a password using the number key.

In some cases, when opening the door lock 10, if the user terminal 20 near the door lock 10 without the user running the key management application, the encryption key information automatically through the periodic signal of the door lock 10 It can also be implemented to be active and open.

The door lock system according to the third embodiment of the present invention will be described later. The description similar to the configuration similar to the above-described embodiments will be omitted. The above embodiments do not change the initial encryption key installed in the door lock 10 or the encryption key installed in the user terminal 20 without activating or discarding the encryption key of the user terminal 20 or including a period of use information for rent payment. According to the implementation to control the opening and closing of the door lock 10. On the other hand, the door lock system according to the third embodiment of the present invention has a form of updating both the encryption key installed in the door lock 10 and the encryption key installed in the user terminal 20.

That is, by installing a module that can communicate with the management server 40, such as Wi-Fi in the door lock 10, generates a new encryption key or update the encryption key every time a payment is made, the door lock 10 and the user terminal 20 Both install identically. If the payment is not made for a certain period of time, it is possible to disable or update the encryption key in the door lock 10 so that the door lock 10 cannot be opened with the encryption key of the user terminal 20 previously installed.

The door lock system according to the fourth embodiment of the present invention will be described later. The description similar to the configuration similar to the above-described embodiments will be omitted. Unlike the above-described embodiments, the door lock system according to the fourth embodiment of the present invention is updated only to the door lock 10 through the management server 40. For example, only the period information is updated without changing the encryption key and transmitted only to the door lock 10 side. When the normal payment is made, update the encryption key information on the door lock 10 side, so that the door lock 10 can be opened with the encryption key installed in the user terminal 20 for a predetermined period.

A control method of the door lock 10 according to the fifth embodiment of the present invention will be described with reference to FIG. 4. 4 is a flowchart illustrating a control method of the door lock 10 according to the fifth embodiment of the present invention. The door lock 10 is already provided with an encryption key, the tenant or the user of the rental building to install the key management application in the user terminal 20 (S10). At this time, if the landlord has already registered the tenant's information, such as a telephone number through the management server 40, the encryption key of the door lock 10 of the lease is automatically installed when the tenant's key management application is executed, In some cases, the tenant may register the information of the tenant, the tenant's information, or the like, and receive an encryption key of the corresponding tenant after user authentication (S11). The encryption key is a key that can be used for a certain period of time, and the entry and exit of the door lock 10 is allowed (S13).

If the fee for use for a certain period of time (rental fee) is settled, the management server 40 allows access to the door lock 10 for a period of time by updating or using, extending or using the encryption key installed in the user terminal 20. (S17). If payment for a certain period of time (rental fee) is not made, the door lock 10 is prohibited from entering (S19). As described above, the method of prohibiting access of the door lock 10 may be implemented by disabling the encryption key installed in the user terminal 20 or by using the encryption key installed in the door lock 10.

If the contract expires, the landlord can use the encryption key assigned to the landlord (S23).
