Abstract
Description
Technical Field
[0001] The present invention relates to an unlocking system for unlocking a door provided at an entrance of an apartment house.
Background Art
[0002] In apartment houses such as condominiums, there are so-called auto-lock doors that are electrically locked and unlocked at the common entrance. Visitors to the apartment house call the destination from an intercom or the like provided near the common entrance and have the door unlocked to enter the building.
[0003] In recent years, the number of operators providing a drop-off service as a service of a delivery company has been increasing. Drop-off refers to a service of delivering goods or the like non-face-to-face to a designated location, and the designated location is not limited to a delivery box, and may include the inside of the common entrance such as in front of the entrance of a dwelling unit in an apartment house. In addition, this type of service is not limited to delivery companies, but is also carried out when stores or shops such as online supermarkets and consumer cooperatives directly deliver.
[0004] However, when the front of the entrance of a dwelling unit is designated, a delivery company or the like needs to have the auto-lock door of the common entrance opened. Therefore, when the delivery destination (visiting destination) is absent, it cannot be delivered to the designated location and has to be taken back. In response to such problems, for example, a server device and a door control device described in Patent Document 1 have been proposed.
[0005] Patent Document 1 describes that a server device includes a storage means for storing a service number set by a delivery company for each user, a request receiving means for receiving an unlocking request including the device ID and the service number of the door control device from the door control device, an authentication means for performing authentication based on the information included in the unlocking request received by the request receiving means and the information stored in the storage means, and an unlocking instruction means for transmitting an unlocking instruction to the door control device when the authentication is successful.
[0006] According to the configuration described in Patent Document 1, when the delivery service provider arrives at the entrance of the apartment building and causes the door control device to acquire the service number, authentication is performed in the server device and the door is unlocked by the door control device. As a result, the delivery service provider can unlock the door without the user's permission.

Summary of the Invention
Problems to be Solved by the Invention
[0008] However, in the invention described in Patent Document 1, since the door control device on the apartment building side needs to communicate with the server device, it costs to modify the existing door control devices such as auto-lock. Also, for example, when a failure occurs in the communication equipment of the apartment building, it may not be possible to communicate with the server device and the system may not operate normally.
[0009] The present invention aims to solve the above problems and provides an unlocking system that can simplify the configuration on the apartment building side and facilitate introduction.
Means for Solving the Problems
[0010] The invention described in claim 1, which was made to solve the above problems, is installed near the entrance of an apartment building, and includes a first key generation unit that generates first key information for unlocking the door of the entrance, and an input key for inputting second key information generated externally. It has an unlocking device and a terminal device carried by a visitor to the apartment building and having an output unit that outputs the second key information. The unlocking device collates the second key information input from the input key with the first key information generated by the first key generation unit, and unlocks the door when they match. The first key information and the second key information have a defined validity period. This is an unlocking system characterized by this.
Effect of the Invention
[0011] As described above, according to the present invention, the unlocking device installed near the entrance of an apartment building has a first key generation unit and generates the first key information by itself, so there is no need to communicate with a server device or the like. Therefore, it is only necessary to install the unlocking device near the entrance, and the renovation on the apartment building side can also be minimized. Thus, the introduction of the system becomes easy.

Embodiments for Carrying Out the Invention
[0013] A unlocking system according to an embodiment of the present invention will be described with reference to FIGS. 1 to 8. FIG. 1 is a schematic configuration diagram of the unlocking system according to an embodiment of the present invention.
[0014] The unlocking system 1 includes an unlocking device 10, a contractor terminal 30, and a server device 40.
[0015] The unlocking device 10 is provided near the common entrance of an apartment building 100 such as a condominium. In addition, an automatic door 20 is installed at the common entrance. The resident inputs a key, a card key, a password, etc. into an intercom device 21 (see FIG. 2) provided near the automatic door 20 to unlock the automatic door 20 and enter the building. On the other hand, a visitor who does not have a key or the like operates the intercom device 21 to call the destination. In addition, a contractor who can use the unlocking system 1 according to the present embodiment can enter the building without calling the destination by the method described later.
[0016] The installation state of the unlocking device 10 will be described with reference to FIGS. 2 and 3. FIG. 2 is a view showing the vicinity of the common entrance of the apartment building 100. In FIG. 2, the automatic door 20 is shown on the left side. And the unlocking device 10 is provided on the wall surface near the automatic door 20.
[0017] FIG. 3 shows an enlarged view of the unlocking device 10. The unlocking device 10 includes a main body portion 10a and a door portion 10b. Note that the shape of the unlocking device 10 is not limited to the shape shown in FIG. 3. For example, the shape of the main body portion 10, the opening / closing direction and shape of the door portion 10b, etc. may be variously deformed without departing from the gist of the present invention.
[0018] The main body portion 10a is fixed to the above-described wall surface. The main body portion 10a is provided with an input key 12 described later. The input key 12 is configured as a so-called numeric keypad, and numbers from 0 to 9, "*", and "#" can be input.
[0019] The door part 10b is rotatably attached to the main body part 10a by a hinge or the like. FIG. 2 shows the state where the door part 10b is closed, and the input key 12 is covered and hidden by the door part 10b. FIG. 3 shows the state where the door part 10b is open. A display part 13 is provided on the back side 10b1 of the door part 10b. The back side 10b1 is the surface that is not exposed to the outside when the door part 10b is closed. In FIG. 3, a two-dimensional code is displayed as the display part 13. This two-dimensional code is, for example, pasted on the back side 10b1 as a sticker or the like. The display in this embodiment includes not only screen display but also those by printed matters such as stickers.
[0020] FIG. 4 shows the functional configuration of the unlocking device 10. The unlocking device 10 includes a first key generation unit 11, an input key 12, and a display part 13. The first key generation unit 11 generates first key information which is a password for unlocking the automatic door 20 by a method to be described later. The first key generation unit 11 can be made to function by a predetermined program operating on, for example, a microprocessor composed of a CPU (Central Processing Unit) and a memory or the like. That is, the unlocking device 10 incorporates a control device such as a microprocessor.
[0021] The input key 12 is configured by a numeric keypad as described above. Note that it may include keys such as alphabets, not limited to the numeric keypad. Also, it may be an input device such as a touch panel, not limited to a physical key.
[0022] The display part 13 is configured by a two-dimensional code as described above. This two-dimensional code includes property identification information such as a unique ID for identifying the apartment house 100 and a URL (Uniform Resource Locator) for accessing the server device 40 to be described later. Note that it is not limited to a two-dimensional code, and it may be a one-dimensional code or a character string in which property identification information or the like is encrypted according to a predetermined rule. Also, it is not limited to being pasted on the back side 10b1 of the door part 10b as a sticker, and a liquid crystal display or the like may be provided on the main body part 10a for screen display.
[0023] The operator terminal 30 is a terminal device owned by a parcel delivery operator such as a home delivery operator. Note that this embodiment is applicable not only to parcel delivery operators but also to operators who perform door-to-door delivery such as the above-mentioned online supermarkets and newspaper delivery. The operator terminal 30 can use, for example, a smartphone. FIG. 5 shows the functional configuration of the operator terminal 30. The operator terminal 30 includes an output unit 31, an acquisition unit 32, an input unit 33, and a communication unit 34.
[0024] The output unit 31 functions as a display device such as a liquid crystal display of a smartphone and displays (outputs) the second key information described later. Note that the output unit 31 is not limited to display and may be voice output.
[0025] The acquisition unit 32 acquires the two-dimensional code attached to the back side 10b1 of the door portion 10b. Specifically, for example, the two-dimensional code is read by an imaging device such as a camera of a smartphone. The information (image) of the two-dimensional code acquired by the acquisition unit 32 is extracted with a predetermined program operating on a microprocessor or the like of the smartphone, such as property identification information and a URL for accessing the server device 40.
[0026] The input unit 33 has an operator authentication code, which will be described later, input thereto. The input unit 33 functions as an input device (such as a touch panel) of a smartphone, for example.
[0027] The communication unit 34 communicates with the server device 40 via a network N such as a mobile communication network or the Internet. The communication unit 34 is composed of, for example, a communication circuit corresponding to a mobile communication system such as 4G (4th Generation Mobile Communication System) or 5G (5th Generation Mobile Communication System), or a communication circuit corresponding to a wireless communication system such as Wi-Fi (registered trademark).
[0028] The server device 40 generates second key information based on the property identification information and the like received from the merchant terminal 30, and transmits it to the merchant terminal 30. The server device 40 is composed of a well-known server computer. FIG. 6 shows the functional configuration of the server device 40. The server device 40 includes a second key generation unit 41 and a communication unit 42.
[0029] The second key generation unit 41 generates second key information, which is a password for unlocking the automatic door 20. The second key generation unit 41 can be made to function by, for example, a computer program operating on a microprocessor composed of a CPU (Central Processing Unit) and a memory.
[0030] The communication unit 42 communicates with the merchant terminal 30 via the network N. The communication unit 42 can be made to function by a network interface of the server computer.
[0031] Next, the generation methods of the first key information and the second key information in the first key generation unit 11 and the second key generation unit 41 will be described. The first key generation unit 11 and the second key generation unit 41 generate the first key information and the second key information respectively using the same algorithm. In the present embodiment, the first key information and the second key information are generated as time-limited passwords. A time-limited password is a password that is valid only for a specific period.
[0032] The above-mentioned time-limited password is generated based on a local key, a key type, and date information. The local key is the above-mentioned property identification information. In the present embodiment, three types of key types, namely, a daily key, a monthly key, and a time key, can be set. The daily key is a key that can be used throughout the day (one day). The monthly key is a key that can be used for a longer period than the daily key for one month or the like. The time key is a key that can be used for a limited time such as one hour from the time of issuance, which is shorter than the daily key. The date information is information consisting of year, month, day, and hour (current date and time information), but only the necessary digit range needs to be used depending on the key type. For example, for the daily key, year, month, and day can be used, for the monthly key, year and month can be used, and for the time key, year, month, day, and hour can be used.
[0033] For example, in the case of a time key, one day may be divided into multiple time zones such as every 1.5 hours or every 2.5 hours, and the PIN may be changed according to the time zone based on the "hour" of the current date and time information. Also, instead of one day (24 hours), the time zone with a usage plan such as 3:00 to 22:00 may be divided. Also, the divided time zones are not limited to non-overlapping time zones such as 11:00 to 13:30 and 13:30 to 16:00, and may be partially overlapping such as 11:00 to 13:30 and 13:00 to 15:30. When they are partially overlapping, the overlapping time zones can be unlocked with either time key.
[0034] Alternatively, for example, in the case of a time key, the time-limited PIN generated in the 8 o'clock hour and the time-limited PIN generated in the 9 o'clock hour may be different. In this case, the time key becomes a time-limited PIN with a maximum validity period of 1 hour. That is, in this case, there is no need to separately set information indicating the validity period by using the date information for the time-limited PIN.
[0035] In the first key generation unit 11, the local key may be set at the time of installation of the unlocking device 10. If the first key generation unit 11 includes a circuit for timekeeping, etc., it is possible to calculate three types of keys: daily key, monthly key, and time key.
[0036] In the second key generation unit 41, the local key (property identification information) is extracted by the operator terminal 30 reading the display unit 13 (two-dimensional code), and is acquired via the communication unit 34, the network N, and the communication unit 42. Then, the second key information is generated based on the local key, the type of key, and the date information.
[0037] Specifically, the merchant terminal 30 accesses the server device 40 via the URL included in the two-dimensional code. At this time, property identification information (local key) is also transmitted. The server device 40 requests the merchant terminal 30 to input a merchant authentication code. The merchant authentication code is a code assigned to each merchant (such as a courier or a newspaper delivery merchant) and corresponds to the visitor identification information. When the merchant authentication code is input from the merchant terminal 30, the server device 40 checks whether the input merchant authentication code is registered in the server device 40. If it is registered, the authentication is considered successful. Then, the transmitted local key is treated as valid.
[0038] Also, in the server device 40, for example, the type of key is set for each merchant, such as a time key for a courier and a monthly key for a newspaper delivery merchant. Therefore, the type of key corresponding to the authenticated merchant is specified. Then, the second key generation unit 41 generates a time-limited password (second key information) using the same algorithm as the first key generation unit 11 based on the acquired local key, the date information acquired from the timekeeping function of the server device 40, and the specified key type, and transmits it to the merchant terminal 30. That is, the date information (current date and time information) changes the range of use according to the merchant (visitor) among the year, month, day, and time that make up the date information.
[0039] Next, the operation of the unlocking system with the above-described configuration will be described with reference to the sequence diagram of FIG. 7. First, a visitor such as a courier opens the door portion 10b of the unlocking device 10 to expose the display unit 13 and reads the two-dimensional code with the merchant terminal 30 (S1).
[0040] The business operator terminal 30 extracts the access URL to the server device 40 from the read two-dimensional code and accesses the URL. Then, the server device 40 requests the input of the business operator authentication code. The visitor inputs the business operator authentication code using the touch panel or the like of the business operator terminal 30. The server device 40 performs authentication based on the input business operator authentication code (S2). If the authentication is successful (OK), it acquires the local key and generates the second key information with the second key generation unit 41 (S3), and transmits it to the business operator terminal 30. On the other hand, if the authentication fails (NG), it transmits an error message or the like to the business operator terminal 30.
[0041] Next, the business operator terminal 30 causes the received second key information to be displayed on a display device such as a liquid crystal display (S4). The visitor inputs the displayed second key information from the input key 12 of the unlocking device 10.
[0042] Next, in the unlocking device 10, the first key generation unit 11 generates the first key information. At this time, the first key generation unit 11 generates three types of first key information: the daily key, the monthly key, and the time key (S5). Note that the generation of the first key information is not limited to this timing. For example, an optical sensor or the like may be provided in the main body of the unlocking device 10 to detect that the door portion 10b has been opened, and the first key information may be generated at that timing.
[0043] Next, in the unlocking device 10, the generated first key information is compared with the second key information input from the input key 12 (S6). Here, since three types of first key information are generated, it is only necessary to match one of them. By doing so, the unlocking device 10 does not need to have information of the business operator such as the business operator authentication code, and communication with the outside becomes unnecessary.
[0044] If the result of the comparison matches (OK), the unlocking device 10 unlocks the automatic door 20 (S7). On the other hand, if the result of the comparison does not match (NG), the automatic door 20 is not unlocked. At this time, the unlocking device 10 may display an error message or the like, or output a warning sound.
[0045] The generation timings of the first key information and the second key information do not have to be each time the lock is unlocked as shown in the sequence diagram of FIG. 7. For example, the first key information and the second key information may be generated periodically, such as once a day or once a month, and stored inside the unlocking device 10 or inside the server device 40 as a library or the like.
[0046] In the above-described embodiment, the business operator terminal 30 acquires the second key information by reading the two-dimensional code. However, the visitor may acquire the second key information by voice by making a phone call. A method for acquiring the second key information by phone will be described with reference to the sequence diagram of FIG. 8.
[0047] First, the visitor opens the door portion 10b of the unlocking device 10 to expose the display unit 13. At this time, the display unit 13 has a serial number consisting of a plurality of digits. The visitor calls the phone number (system number) to which the server device 40 responds. Note that the system number may be preset in the business operator terminal 30.
[0048] The server device 40 outputs a request for input of the serial number by voice guidance or the like. The visitor inputs the serial number from a touch panel or the like. This serial number serves as a local key. Next, the server device 40 outputs a request for input of the business operator authentication code by voice guidance or the like. The visitor inputs the business operator authentication code from a touch panel or the like. Authentication (S2) and generation of the second key information (S3) are the same as those in FIG. 7. However, the generated second key information is output as voice (S4'). Thereafter, it is the same as in FIG. 7.
[0049] According to the present embodiment described above, the unlocking system 1 includes an unlocking device 10 installed near the common entrance of the apartment building 100, the unlocking device 10 including a first key generation unit 11 that generates first key information for unlocking the automatic door 20 of the common entrance, and an input key 12 that inputs second key information generated externally. The unlocking system 1 also includes a contractor terminal 30 held by a visitor to the apartment building 100, the contractor terminal 30 including an output unit 31 that outputs the second key information. The unlocking device 10 collates the second key information input from the input key 12 with the first key information generated by the first key generation unit 11, and unlocks the automatic door 20 when they match. The first key information and the second key information are defined with an expiration period.
[0050] Since the unlocking system 1 is configured as described above, the unlocking device 10 installed near the common entrance of the apartment building 100 includes the first key generation unit 11 and generates the first key information by itself, so there is no need to communicate with a server device 40 or the like. Therefore, it is only necessary to install the unlocking device 10 near the common entrance, and the renovation of the apartment building 100 can be minimized. Accordingly, since the unlocking device 10 does not require a communication function, the configuration can be simplified, and the introduction of the system becomes easy.
[0051] In addition, since the first key information and the second key information are defined with an expiration period, abuse of the key information can be prevented, and for example, the auto-lock function of the automatic door 20 of the apartment building 100 can be prevented from being impaired.
[0052] The unlocking device 10 further includes a display unit 13 that displays a two-dimensional code including a local key for identifying the apartment building 100. The first key generation unit 11 generates the first key information based on the local key. The contractor terminal 30 includes an acquisition unit 32 that acquires the local key. The output unit 31 outputs the second key information generated based on the local key. By doing so, unique key information can be generated for each property. Therefore, reuse of the key information can be prevented, and security can be improved.
[0053] In addition, it has a second key generation unit 41 that generates second key information. The second key generation unit 41 generates the second key information based on the local key and the date information, and the first key generation unit 11 generates the first key information based on the local key and the date information. By doing so, since the date information is utilized, it becomes easy to limit the valid period.
[0054] Also, as the current date and time information, since the range used according to the operator changes among year, month, day, hour, minute, it is possible to easily set the expiration date according to the type of key for each operator.
[0055] In addition, the operator terminal 30 includes an input unit 33 for inputting an operator authentication code for identifying the operator, and the second key generation unit 41 generates the second key information after authenticating the operator based on the operator authentication code. By doing so, it is possible to authenticate that the operator is a registered legitimate operator, and unauthorized use of the system can be prevented.
[0056] In addition, since the second key generation unit 41 functions as a server device 40 that can communicate with the operator terminal 30, it can be adapted even if the processing ability of the operator terminal 30 is low. Also, since the generation of the second key information is done in a batch, operator registration and the like are also easy.
[0057] Note that in the above-described embodiment, the server device 40 generates the second key information, but it may be generated by the operator terminal 30. That is, the operator terminal 30 may have the function of the second key generation unit.
[0058] In addition, in the above-described embodiment, the unlocking device 10 was provided near the main entrance (main entrance), but it is not limited thereto. For example, any entrance having a door that is locked and unlocked by an electric lock such as a sub-entrance, an elevator hall, an emergency exit, or a general entrance dedicated to operators may be used.
[0059] In the above-described embodiment, the explanation was given in terms of a contractor who delivers luggage or the like. However, for example, it can be similarly applied to a maintenance company for shared equipment such as elevators or a cleaning company. Therefore, it is not necessary for a person in charge of the management company to be present, or to lend a key for entering the building or the like. As a result, for example, it becomes possible to respond promptly in the event of an emergency such as a failure, and the loss of keys or the like can be prevented.
[0060] Further, the present invention is not limited to the above-described embodiment. That is, those skilled in the art can variously modify and implement it in accordance with conventionally known knowledge without departing from the gist of the present invention. As long as the configuration of the unlocking system of the present invention is still provided even by such a modification, of course, it is included in the scope of the present invention.
