  However, in the case of the configuration of Patent Document 1 described above, a password storage unit having a sufficient capacity is required in order to issue a different password for each visitor regardless of the situation, and the valid time is managed for each password. The configuration of the password timer for time management was also complicated.

  Therefore, in view of such a problem, the present invention can simplify the configuration of the password storage unit and the password timer by using the password issued immediately before for a visitor who satisfies a specific condition. The purpose is to provide an apartment intercom system that does not compromise security.

In order to solve the above-mentioned problem, the invention of claim 1 is provided at a main entrance of an apartment house and has a function of a visitor calling a resident to make a call, and an individual floor entrance. Alternatively, a plurality of second collective entrance machines installed at each building entrance and having a function of calling a resident, a living room master machine installed at each dwelling unit and having a function of responding to calls from the collective entrance machine, and a set Corresponding to a control device that controls communication between the entrance machine and the parent room, a first automatic door that is installed at the main entrance and restricts entry into the apartment house, and each second entrance machine It is installed at each floor entrance or building entrance and has a plurality of second automatic doors for restricting access to each floor or building, and the first and second automatic doors are unlocked by the living room master unit. When the unlocking signal is output from the room master that has received the call to the first collective entrance door, the first automatic door is unlocked and the password for unlocking the second automatic door is issued. This is a collective housing intercom system having an automatic door unlocking control unit that unlocks the second automatic door by displaying it on the first collective entrance machine and inputting the issued password to the second collective entrance machine corresponding to the second automatic door. The control device has a password storage unit that stores the password displayed on the first collective entrance machine, and a password timer that counts the password validity time, and the automatic door unlocking control unit determines the validity time of the issued password. If the unlocking signal is received by the resident's calling operation from the first entrance hall, the password timer is restarted to extend the valid time Together, and wherein the displaying the first set entrance machine by reusing the password being issued.
According to this configuration, if the previously issued password is valid, the password storage unit and the password timer are installed in order to extend the valid time of the password being issued without issuing a new password. It can be simplified. Since the password is continuously used only when the previously issued password is alive, the password cannot be used after a certain period of time even if it is slightly extended, and security is not impaired.

According to a second aspect of the present invention, in the configuration according to the first aspect, the control device includes a dwelling unit location storage unit that associates the living room master unit with at least one second collective entrance unit, and includes an automatic door unlocking control unit. Is characterized in that an unlock signal is not issued when the second living room parent machine to which the password has been inputted is not associated with the living room parent machine that has responded.

The first automatic door 7 for restricting entry into the apartment house is a second automatic door 7 installed at each floor entrance or building entrance to restrict entry into each floor or building. A plurality of second collective entrance machines 2 and second automatic doors 7 are installed in pairs.

  The first collective entrance machine 1 and the second collective entrance machine 2 are connected to the control device 4 via the collective entrance machine trunk line L1, and the living room master unit 3 is connected to the control device 4 via the master machine trunk line L2 for management. The room master 5 is connected to the control device 4 via the transmission line L3. The first automatic door 6 is connected to the corresponding first collective entrance machine 1 via the control line L4, and the second auto door 7 is connected to the paired second collective entrance machine 2 via the control line L5. .

  As shown in FIG. 1, the control device 4 includes a collective entrance machine ID storage unit 41 a, a dwelling unit number storage unit 41 b that associates the dwelling unit number with the room ID, a password storage unit 41 c that stores the issued password, and each second An effective time storage unit 41d that stores an effective time of a password set for the automatic door 7, a dwelling unit location storage in which the living room base unit 3 and at least one second collective entrance 2 (and the corresponding second automatic door 7) are associated with each other. Unit 41e, unlocked floor storage unit 41f for storing the selected second collective entrance machine 2, password timer 42 for managing the password valid time, main control unit 43 for controlling the entire control device 4, and first collective entrance machine 1 The first interface (first IF) 44a that communicates with the office, the second interface (second IF) 44b that communicates with the living room base unit 3, and the management room base unit 5 The third interface comprises a (first IF) 44c, and the like.

  In addition, the 1st collective entrance machine 1 and the 2nd collective entrance machine 2 display the operation units 11 and 21 which select the dwelling unit to call (select a living room master), the cameras 12 and 22 which image a visitor, and various information Display units 13 and 23, microphones 14 and 24 for calling, and speakers 15 and 25. The room master unit 3 also includes a call button 31 that receives a call and responds, a monitor 32 that displays a visitor image, an unlock button 33 that unlocks the automatic door, a microphone and a speaker for making a call, and the like.

  The operation of the apartment house intercom system configured as described above will be described below. However, when the call operation from the first collective entrance machine 1 or the second collective entrance machine 2 is performed, the cameras 12 and 22 start imaging and are displayed on the living room base unit 3, and the call call operation from the management room base unit 5 The description is omitted because it is the same as in the prior art. Here, a visitor calls a desired resident from the first collective entrance 1 to make a call, and the visitor then unlocks the second automatic door 7. The flow will be described mainly.

  When a visitor operates the first collective entrance 1 from the main entrance and inputs a dwelling unit number or the like in order to call a resident at the visit destination, the home unit of the dwelling unit at the destination is called via the control device 4. A call signal is transmitted to 3, and a ringing tone sounds in the callee's room master unit 3. When the resident who recognizes the ringing sound performs a response operation on the room base unit 3, a call path is formed with the first collective entrance machine 1 as a call source under the control of the control device 4, and a call can be made. When the unlocking button 33 of the living room master unit 3 is operated by the resident who has confirmed the visitor through the call in this way, an unlocking signal is output to the control device 4.

  Upon receiving the unlock signal, the control device 4 generates a password (for example, a two-digit number) by the main control unit 43, and sends it to the first collective entrance 1 together with the unlock signal for unlocking the first automatic door 6. Send. Further, based on the dwelling unit number (rooming unit ID) of the living room base unit 3 that has output the unlock signal, the second automatic door 7 that the visitor enters from the dwelling unit location storage unit 41e is read, and the second automatic door 7 that passes through is read. The valid time set in the above is read from the valid time storage unit 41d, the password timer 42 is set to the read valid time, and counting is started.

  Here, the selection of the second automatic door 7 will be specifically described. For example, in the case of an apartment house consisting of a plurality of floors, a floor is configured for each floor. Then, the visitor goes to the floor with the target dwelling unit by an elevator or stairs. In this case, the second automatic door 7 is installed in front of the elevator (and in front of the stairs). Therefore, since it does not usually pass through floors other than the floor with the target dwelling unit, the 2nd automatic door 7 which passes inevitably is specified. In other words, since the second automatic door 7 that does not pass through is determined, the second automatic door 7 other than the specific second automatic door 7 can be set so as not to be unlocked even if a password is input. We can expect up.

  Further, the main control unit 43 stores the issued password in the password storage unit 41c, and stores the ID of the selected second automatic door 7 (corresponding second collective entrance machine ID) in the unlocked floor storage unit 41f.

  Upon receiving the password and the unlock signal, the first collective entrance 1 displays the password on the display unit 13 and transmits the unlock signal to the first automatic door 6 to unlock it. At this time, the display unit 13 of the first collective entrance 1 also displays that the displayed password is a password for unlocking the second automatic door 7 on the way to the visited site.

A visitor who has recognized the password displayed on the first entrance door 1 enters the apartment house through the unlocked first automatic door 6, moves to the visited floor using an elevator or the like, and enters the floor entrance. The unlocking operation of the installed second automatic door 7 is performed.
This unlocking operation is performed by inputting a password to the second collective entrance 2 installed near the second automatic door 7.

Specifically, the second collective entrance machine 2 is set to a predetermined password input mode, and the password displayed on the first collective entrance machine 1 is input. The second collective entrance 2 to which the password is input transmits the input password information to the control device 4. Upon receiving this password information, the control device 4 determines whether the main control unit 43 has the correct password, is valid, or is not from the second collective entrance 2 associated with the prohibited second automatic door 7. The password storage unit 41c, the password timer 42, and the unlocking floor storage unit 41f are respectively referred to for determination, and when all are cleared, an unlocking signal is transmitted to the second collective entrance machine 2.
Receiving this unlock signal, the second collective entrance 2 unlocks the second automatic door 7. Thus, the visitor can go through the second automatic door 7 to the target dwelling unit.

If the password is not correct, for example, an input request message is displayed again. If it is outside the valid time, a message such as time out is displayed. Further, when proceeding before the second automatic door 7 on the prohibited floor, a message indicating that the floor is different is displayed on the second collective entrance 2.
If the visitor forgets the password, the resident may be called from the second collective entrance machine 2 and unlocked as with the operation at the first collective entrance machine 1.

In this way, the second automatic door 7 that does not pass through before visiting the destination does not unlock even when a password is input, and thus security can be improved.
In addition, since the effective time can be set for each second collective entrance 2, the effective time can be optimally set according to the distance from the first collective entrance 1, etc. Can be prevented from becoming unnecessarily long or insufficient, preventing inconvenience to visitors and maintaining high security.

  Next, a case where a new visitor calls the first collective entrance machine 1 within the validity period of the previously issued password will be described. When a new visitor calls the room master unit 3 from the first collective entrance 1 and makes a call and the unlock signal of the first automatic door 6 is output from the room master unit 3 to the control device 4, the main control unit 43 It is determined from the count status of the password timer 42 whether the previously issued password is valid. If it is valid, it is determined whether or not a new visitor's destination is associated with the same second automatic door 7 as the previous visitor based on the information in the dwelling unit storage unit 41e.

As a result, when it is recognized that it is associated with the same second automatic door 7, a new password is not generated and the password being issued is continuously used. However, the password timer 42 is reset and restarted at the time read from the valid time storage unit 41d.
Therefore, the password memorize | stored in the password memory | storage part 41c is transmitted to the 1st collective entrance machine 1, and is displayed.

FIG. 2 shows a timing chart of the password valid time in this case, that is, when the valid time is extended without changing the password. T1 indicates the time for which the password is displayed on the first collective entrance 1 and T11 indicates the valid time for the issued password. As shown in FIG. 2, when an unlock signal is output from the room master unit 3 to a visitor who comes later, the password timer 42 is reset regardless of the elapsed time of the password being issued, and is set in advance. The counting of the valid time T11 is resumed.
In this way, when the visitor inputs the password displayed on the first collective entrance 1 to the second collective entrance 2 as described above, the second automatic door 7 is unlocked and it is possible to go to the visited residence. .

  In addition, if the visitor of the visitor who came later is a dwelling unit on a different floor, even if the password issued immediately before is still valid, a new different password will be issued and the valid time will also be newly set The validity time of the previously issued password does not change.

  In this way, if the previously issued password is in a valid time zone, the password storage unit 41c and the password timer 42 are provided to extend the validity time of the password being issued without issuing a new password. It can be simplified. Since the password is continuously used only when the previously issued password is alive, the password cannot be used after a certain period of time even if it is slightly extended, and security is not impaired.

In the above embodiment, the password valid time is extended for visitors who go to the same floor, but even if the visitor goes to a different floor, the previous password is valid. For example, the time may be extended without changing the password, and the password storage unit 41c and the password timer 42 can be greatly simplified.
Moreover, although the case where there was one first collective entrance machine 1 was described, when there are a plurality of main entrances, a plurality of first collective entrance machines 1 are also installed. In this case, password issue control may be performed with each first collective entrance machine 1 being made independent. Furthermore, an ID for recognizing the first collective entrance machine of the issuer may be added to the password to be issued.
