Description

  The present invention relates to an intercom system that combines the simplicity and functionality of an auto-lock entrance gate and a mobile phone terminal to improve the security function of an auto-lock door of an apartment house such as an apartment.

  Nowadays, the population leaving their parents and living alone in the city is accelerating. Most of these populations live in condominiums and apartments, and then go to schools and businesses. For this reason, due to their lifestyle, visitors to condominiums and apartments that are homes are limited to a small number of acquaintances such as friends, lovers, and families. On the other hand, many other visitors do not expect to visit. When you want to go home late at night or sleep slowly on a holiday in a busy life alone, there are many cases where you come to visit sales or malicious solicitation aimed at living alone. Recently, stalker crimes such as locating addresses by some means and confirming the absence situation, and detective investigations, etc., are also common in the city. With the current intercom system, even those who don't want to talk to each other have to talk between the intercoms, and it's easy to end the conversation with that kind of person. And not. Sometimes it develops into trouble. In order to avoid these problems without causing stress to residents, it is necessary to fundamentally change the conventional intercom system so that conversations with unnecessary visitors are not established.

  In general, intercom systems for collective housing in condominiums, etc. are installed at common entrances, and are installed in rooms connected to the entrance device that makes a desired room call by key operation, and in response to calls from there. It consists of an indoor device that can unlock the auto-lock door of the common entrance.

  When visiting a family member or an acquaintance living in an apartment, it is normal to call a person in the room by pressing the number key such as the room number in front of the auto-lock door (the door release key or release pass). Is usually not announced by anyone other than you.) There is no problem with the doorbells for people who know to visit in advance. There are many cases that are sounded. A doorbell that you don't recognize is just a private infringement, and sometimes even a horror. If the inhabitants of the room do not respond to the unlocking, the entry of those uninvited persons can be avoided, but it is not possible to exclude those who are repeatedly called by a doorbell or who do not want to stop talking. Assuming the worst case, vacant nests, etc. first ring the doorbell, often confirm the absence of the resident in the room before moving to the crime, and there is no prior appointment to prevent this. For those who do not, as much as possible not to give the absence information of the room will also strengthen the security.

  Patent Literature 1 (Japanese Patent Laid-Open No. 2006-184985), etc., as a document disclosing an interphone system using a mobile phone terminal, and a patent disclosing a door locking / unlocking system using a mobile phone terminal Document 2 (Japanese Patent Laid-Open No. 2006-345444) exists.

  The one described in Patent Literature 1 is called to the mobile phone terminal of the telephone number registered in the intercom device when the call bell button is pressed, and an image taken by the intercom device is displayed on the display of the mobile phone terminal, The system is designed to make calls, and using a mobile phone terminal improves convenience and simplicity, but does not attempt to enhance security in the system itself.

Patent Document 2 discloses that a telephone number of a mobile phone terminal is registered as identification information for locking / unlocking to open / close the door, and that registration / deletion can be performed only by a manager's mobile phone. However, the power supply to the mobile phone terminal is not taken into consideration, and if the battery of the mobile phone terminal is dead, the door cannot be unlocked and the versatility is low.

  The present invention is installed in a common entrance and makes a desired room call by key operation, and is installed in a room with a wired connection thereto, and the door of the common entrance can be unlocked in response to the call from there. In the intercom system for an apartment house composed of indoor devices, the first problem is that a call to the resident through the entrance device using the mobile phone terminal and the indoor device can be made even when the power of the mobile phone terminal is turned off. In addition, it is possible to avoid an unpleasant call by a visitor who does not want to answer by making a mechanism that the call can be made only by a mobile phone terminal of a specific phone number registered in the phone book in advance, and security of the auto-lock door The function can be improved, and the resident of the room can use his / her mobile phone terminal without using the indoor device directly. It is to be able to the visitor and conversation.

  The second problem is to prevent misuse while ensuring convenience and simplicity by using a mobile phone terminal.

  The intercom system for collective housing of the present invention according to claim 1 reads the telephone number while supplying power to a front door device by connecting a mobile phone terminal to the interface, and transmits it to the indoor device in the room to be called. The telephone number reading means for authenticating the visitor by comparing the telephone number transmitted from the entrance device with the telephone directory database, and the authentication OK. And a terminal-to-terminal communication relay unit that wirelessly connects with the mobile phone terminal of the resident in the room and enables inter-terminal communication with the mobile phone terminal connected to the entrance device.

  In the invention according to claim 2, which is a preferred mode, the inter-terminal communication relay means of the indoor unit establishes inter-terminal communication with the mobile phone terminal that has responded with the highest priority among the plurality of resident mobile phone terminals. To do.

  Similarly, in the invention according to claim 3, the mobile phone terminal connected to the interface of the entrance device is set to the authentication mode from the incoming call waiting mode, and the removal from the entrance device is locked, and an authentication OK response is received from the indoor device side. Terminal lock means for releasing the lock and returning to the incoming call waiting mode.

  Similarly, in the invention according to claim 4, the inter-terminal communication relay means of the indoor unit allows inter-terminal communication for a set time, and the mobile phone terminal connected to the interface of the entrance device and the mobile phone terminal of the resident in the room When either one is disconnected, the terminal lock means is instructed to release the lock.

  Similarly, in the invention according to claim 5, as a function of the telephone number authentication means of the indoor unit, the telephone number of the mobile phone terminal connected to the entrance apparatus is registered in the telephone directory database as a number allowing automatic unlocking. At the same time, an authentication OK response is sent to the entrance device, and the door of the common entrance is automatically unlocked.

  Similarly, in the invention according to claim 6, as a function of the inter-terminal communication relay means of the indoor device, whether the mobile phone terminal connected to the interface of the entrance device and the mobile phone terminal of the resident in the room have a videophone function or not. If both are equipped with a videophone function, videophone communication between these terminals is made possible.

  Similarly, in the invention according to claim 8, as a function of the terminal lock unit of the entrance device, when the same telephone number is continuously stored in the history storage unit for a set number of times or more, the locked state at the time of abnormality is set.

The present invention has the following effects.
<Effect 1> Visits such as annoying third parties and solicitations can be eliminated without bothering the residents of the room.
(Reason) Other people who are not registered in the phone book will not be bothered because they will not be aware of the fact that they have visited, and those who have been maliciously pushed will not be notified to the person due to the nature of the system. Therefore, it will not harass you.
<Effect 2> By using the telephone directory function of the mobile phone terminal, it is possible to determine whether or not the visitor is a related person of the resident of the room. It is possible to conceal the resident's absence information from a third party without an appointment and block visits. The security level of the auto lock door can be improved by using the phone book function of the mobile phone terminal.
(Reason) Since the intercom sounds basically only for those who are registered in the phone book of the resident in the room, the answer can be answered with peace of mind.
<Effect 3> Since the power source of the mobile phone terminal is used from the connected device, the mobile phone terminal can be used as a security key without worrying about running out of the battery.
(Reason) Since the mobile phone terminal is directly connected to the entrance device, power can be supplied from the entrance device.
<Effect 4> The resident's own mobile phone terminal itself serves as an authentication key, and an auto-lock key is not required.
(Reason) Items to be managed when going out are reduced. In addition, when the key is lost, it has no effect on other residents in the apartment.
<Effect 5> An interphone with an image can be used in any room provided that the mobile phone terminal is equipped.
(Reason) Many intercoms with audio only are installed in condominiums, but with this system, intercoms with images can be used in all rooms. Further, since communication is performed between mobile phone terminals, a higher security level than that of a TV image device provided can be expected.
<Effect 6> Since the human interface becomes its own mobile phone terminal, the interphone device can be operated in the same manner even if the environment changes.
(Reason) If the apartment is equipped with the same system, even if you move, you can use the interphone with the same operation feeling as before just by transferring the phone book.
<Effect 7> Vicious abuse can be prevented by limited communication for a certain period of time and continuous connection lock using the same telephone number.
(Reason) It is possible to prevent abuse cases of this intercom system. Furthermore, by leaving the usage history for a certain period in the device, the system user when an important problem occurs can be determined from the mobile phone number history.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  The construction of the intercom system of the present embodiment will be described with reference to FIG. 1. The entrance device 2 of a housing complex such as a condominium is installed in the vicinity of the auto-lock door 5 of the common entrance, and the number key 4 as in the prior art. The room number to be called by pressing can be displayed on the display 11 and the door 5 can be unlocked. In addition to such a function, the entrance device 2 is provided with an interface 2a that can be connected to the mobile phone terminal 3 of the visitor and can supply power to the mobile phone terminal 3 of the visitor. A telephone number reading unit (not shown) that reads the telephone number while supplying power to the mobile phone terminal 3 from the interface 2a and a storage device that stores a connection history to the interface 2a are incorporated. The interface 2a can be mechanically locked so that the inserted mobile phone terminal 3 cannot be removed.

  On the other hand, the indoor unit 7 installed in each room of the apartment house is connected to this by wiring (wired) 14 in the apartment house so that it can respond to calls from the entrance apparatus 2. The indoor device 7 is provided with a speaker microphone 12 and a conversation button 13 for performing a conversation with the entrance device 2 and an unlocking switch 10 for unlocking the door 5 via the entrance device 2 as in the past. Yes. In addition to this, the indoor device 7 includes a telephone book database 9 and a CPU that authenticates the visitor by comparing the telephone number transmitted from the telephone number reading unit of the entrance device 2 with the telephone book database 9. A telephone number authenticating unit (not shown) is connected to the cellular phone terminal 8 of the resident in the room and wirelessly connected to the cellular phone terminal 3 of the visitor connected to the entrance device 2 when the authentication is OK. An inter-terminal communication relay unit (not shown) that enables inter-terminal communication is incorporated.

  In the telephone directory database 9, the telephone directory of the resident-side mobile phone terminal 8 of the resident 6 in the room is registered. The registration is made possible by transmitting to the inter-terminal communication relay unit by infrared communication or the like. If there is a family member or a cohabitant and there are a plurality of resident-side mobile phone terminals 8, all the phone books are registered. In this example, it is assumed that the indoor device 7 and the resident-side mobile phone terminal 8 exchange data with the indoor wireless LAN.

  The visitor 1 presses the room number from the number key 4 on the entrance device 2 with the visitor side mobile phone terminal 3 connected to the interface 2a of the entrance device 2. The indoor device 7 is accessed from the room number information input at the entrance device 2, and the telephone number information of the visitor side mobile phone terminal 3 is searched from the telephone directory database 9 stored in the indoor device 7. When the telephone number is found from the telephone directory database 9, the visitor 1 is proved to be an acquaintance of the resident 6 of the room, and the doorbell of the room sounds. FIG. 1 shows the state.

  Here, if the visitor 1 is not an acquaintance of the resident 6 of the room or knows the telephone number of the resident 6 of the room by some means, but is not registered in the phone book, there will be no doorbell. There is no response. In that case, only the display “Unauthenticated phone number” is output on the display 11 of the entrance device 2, and the visitor 1 is not notified of the absence of the resident 6 in the room. For a meal such as a pizza or a soba restaurant, a delivery member may have a business mobile phone terminal in advance and have the business person register the business mobile phone terminal in the phone book. This is a security consideration on the store side, and there is no particular problem with the actions that should be performed. When the resident-side mobile phone terminal 8 of the resident 6 of the room is connected to the interface 2a of the entrance apparatus 2 and the room number is pressed, personal authentication is performed. In this case, the door 5 is opened instead of the doorbell. That is, the resident-side mobile phone terminal 8 serves as a door key. When the mobile phone terminal 3 is connected to the interface 2a, power is supplied to the mobile phone terminal 3, so that the mobile phone terminal 3 can be used even when the battery is dead.

  Next, after the call bell authentication, after the authentication is OK, the visitor's mobile phone terminal 3 of the visitor 1 receives the authentication OK response signal from the entrance device 2, and the resident's mobile phone of the resident 6 in the room When the telephone terminal 8 wirelessly receives an authentication OK response signal from the indoor device 7, videophone communication is started. If either one of the mobile phone terminals is not compatible with a videophone, it automatically becomes a voice call. FIG. 2 shows the state.

  Two or more residents live in the room, and for the visitor bells registered in common in the phone book database 9 of the indoor unit 7, the resident mobile phone terminals of all the residents 6 in the registered room It is assumed that communication is established with the cellular phone terminal of the resident who is called 8 and responds first.

  Next, switching of settings for the indoor device 7 will be described. The above explanation is for the case where the resident mobile phone terminal 8 of the resident 6 in the room is in a standby state, and if the resident mobile phone terminal 8 is in communication (during conversation, sending / receiving emails, connecting to a PC, etc.) In that case, it is judged and a doorbell is made from the speaker microphone 12 of the indoor unit 7. In this case, a voice conversation with the entrance apparatus 2 can be performed while the conversation button 13 is being pressed by the same operation as a normal intercom. When the resident-side mobile phone terminal 8 of the room resident 6 does not catch the wireless response of the indoor device 7, it is determined that the resident 6 of the room is absent, and the display 11 of the entrance device 2 indicates “absent or power is turned on. The display of “Not available” is output. FIG. 3 shows the state.

With reference to the sequence diagram of FIG. 4 and the flowcharts of FIGS. 5 and 6, the operation of the above embodiment will be supplementarily described with a specific example.
When the visitor-side mobile phone terminal 3 is connected to the entrance apparatus 2, it is switched to a dedicated mode corresponding to this system, unlike the normal standby state (step S1 in FIG. 5). For convenience, this is referred to as “authentication mode”. During the “authentication mode”, other communication cannot be interrupted, and all incoming calls during this period are handled in the same way as during a call.

  In addition, the entrance device 2 mechanically locks the visitor-side mobile phone terminal 3 with respect to the interface 2a so that the lock cannot be released until the “authentication mode” is released. This is a binding to prevent malfunction during removal and abuse of the device. In addition, power is supplied to the visitor-side mobile phone terminal 3 from the entrance device 2, and the system can operate even when the visitor-side mobile phone terminal 3 has no battery. The entrance device 2 is basically in a standby state, and when the mobile phone terminal 3 is inserted, the entrance device 2 returns from the standby state and becomes operable (step S2).

Next, the phone book search operation of the indoor unit 7 will be described with an example.
Assume that three people (A, B, C) live together in the room number 33, and a common acquaintance D of A and B came to visit the apartment when all three people were at home. Since the mobile phone terminal number of the visitor D is registered in the phone book of the mobile phone terminals 8 of the residents A and B, the phone number has already been registered in the phone book database 9 of the indoor device 7.

  When the visitor D comes in front of the door of the apartment, inserts his / her mobile phone terminal 3 into the interface 2a of the entrance apparatus 2, and presses “33” from the number key (step S5), the visitor D's mobile phone terminal 3 Is read by the telephone number reading unit of the entrance device 2 (step S3), the data reaches the indoor device 7 in the room, and the phone book database 9 is searched. As a result, it is registered in the phone books of the residents A and B. When it is found that there is an incoming call, the mobile phone terminals 8 of the residents A and B in the room receive an incoming call. Since A has taken a bath, his mobile phone terminal 8 cannot be picked up, B receives an incoming call from his mobile phone terminal 8, and when communication is started, the incoming call response to A is also terminated. At this time, if the mobile phone terminal 8 of the resident B and the mobile phone terminal 3 of the visitor D are of a model that can make a videophone call to each other, the communication is a videophone (steps S6 to S17). If either the mobile phone terminal B or D is a model that does not support TV phone calls, a voice call is automatically made (steps S18, S19, S20). In addition, when there are a plurality of resident side mobile phone terminals 8 in the same room, inter-terminal communication is established for the mobile phone terminal that has responded with the highest priority.

  As a measure for preventing misuse, the history of the mobile phone terminal number connected to the entrance device 2 is saved to some extent in the storage device in the entrance device 2. Further, when the same mobile number is connected three or more times in succession, the entrance device 2 is mechanically locked so that the visitor-side mobile phone terminal 3 cannot be removed from the entrance device 2. Then, the “authentication mode” is switched to the “emergency mode”, and the mobile phone terminal number is contacted to a security company or the like registered in advance. Therefore, the person who has locked the machine explains the circumstances to the person at the security company on the spot and prevents the mobile phone terminal from being taken out unless the lock is released from the security company side (step S21).

  If the mobile phone terminal inserted into the interface 2a of the entrance apparatus 2 is a resident's (if YES in step S6), the telephone number has already been registered in the phone book database 9 as that of the resident. While the door 5 is automatically opened, the mobile phone terminal is unlocked, the connection history of the mobile phone terminal remains in the storage device of the entrance device 2, and the mobile phone terminal returns to the normal standby state (step S22). .

  If the mobile phone terminal inserted into the interface 2a of the front door device 2 is not registered (NO in step S7), the display 11 of the front door device 2 displays an unauthenticated message and the mobile phone terminal The lock is released, the connection history of the mobile phone terminal remains in the storage device of the entrance device 2, and the mobile phone terminal returns to the normal standby state (step S23).

  When none of the mobile phone terminals 8 in the room responds (NO in step S12), and when the power is not turned on (NO in step S24), the display 11 of the entrance apparatus 2 is absent or the power is not supplied. It is displayed that the mobile phone terminal is not entered, the lock of the mobile phone terminal is released, the connection history of the mobile phone terminal remains in the storage device of the entrance device 2, and the mobile phone terminal returns to the normal standby state (step S25). . When the resident responds at the mobile phone terminal 8 in the room and presses the conversation button 13, a conversation similar to that of a general interphone can be performed (step S26).

  It is assumed that no communication costs are incurred on the user side for the communication in the “authentication mode”. For this reason, in order to prevent a long-time conversation using the abuse, the communication in the “authentication mode” is limited for 3 minutes (steps S27, S28, and S29, respectively). Originally, it is a tool intended to authenticate visitors, so we think that 3 minutes of conversation is enough. Due to this limitation and the three consecutive connection locks described above, the same user can be prevented from monopolizing for a long time. It is assumed that a plurality of interfaces 2a of the entrance apparatus 2 are prepared in order to prevent other users from being able to open the door when locked.

  When either the visitor-side mobile phone terminal 3 or the resident-side mobile phone terminal 8 is disconnected (YES in each of steps S30, S31, and S32), the visitor-side mobile phone inserted into the interface 2a of the entrance apparatus 2 The terminal 3 is unlocked, the connection history of the mobile phone terminal remains in the storage device of the front door device 2, and the mobile phone terminal returns to the normal standby state (step S33).

  In the above embodiment, when the mobile phone terminal of the resident in the room cannot be searched by wireless search, the system immediately notifies the absence to the visitor. It is technically possible to communicate with the mobile phone terminal of the residents in the room where they are out.

  Further, in the above embodiment, the telephone directory database 9 is provided in the indoor device 7, but it may be provided in an external server other than the indoor device 7 so that the indoor device 7 can access the server. The server itself may also serve as the indoor device 7.

  The system according to the present invention can be used not only in an apartment house such as a condominium, but also in an entrance gate of a member-based store.

In the configuration diagram of the intercom system according to the embodiment of the present invention, the mobile phone terminal of the resident of the room is called. Similarly, communication between the resident side mobile phone terminal and the visitor side mobile phone terminal becomes possible. This is when communication is impossible. It is a sequence diagram of operation. It is a flowchart which shows an operation example. It is a flowchart following FIG.
