Description

  The present invention relates to an apartment house intercom system, and more particularly to a controller for an apartment house intercom system configured to facilitate renewal of an apartment house intercom system.

When renewing an apartment house intercom system, building a new system using the wiring used in the old system has become widespread because the cost of wiring work can be reduced (see, for example, Patent Document 1).
However, when renewing by this method, since neither the new nor the old system can be used during the renewal, the visitor cannot call the resident using the central entrance. If this unusable period is, for example, several hours or one day, there will be no major inconvenience to visitors, but there are many devices to be replaced in an apartment house, so the unusable period is several days or one. It took about a week, and during the renewal period, it caused great inconvenience to visitors and residents.
Because of this, it is configured so that the old system can be operated together with the new system and the resident can be called by either the old or new system until the transition to the new system is completed without using common wiring. There are renewal methods that do not bother visitors.

  The old system S2 includes an old collective entrance 61, an old living room master 62, an old management room master 63, an old controller 64, and the like. However, when the new system S1 is connected, the old collective entrance 61 is removed as will be described later.

  The new system S1 is specifically configured as follows. The new collective entrance machine 1 includes an operation unit 11 having a call button and a numeric keypad, a camera 12 for imaging a visitor, a microphone 13 and a speaker 14 for a call, and a collective entrance machine that controls the new collective entrance machine 1 as a whole. A CPU 15 and a collective entrance machine interface (collective entrance machine IF) 16 for communicating with the new controller 4 are provided.

  The new office base unit 2 includes a call button 21 for responding to a call, a microphone 22 and a speaker 23 for a call, a monitor 24 for displaying a captured image of the camera 12, and the like. The new management room base unit 3 includes an operation unit 31 for selecting a room base unit and calling a resident, a handset 32 for calling, and the like.

  The main body 4a of the new controller 4 is a FROM (flash memory) 41 for storing the relationship between the dwelling unit number and the new home base 2 and the ID of the new home base 2 in a state where communication is possible. A controller CPU 42 for controlling the entire controller 4, a controller first interface (controller first IF) 43 for communicating with the new collective entrance machine 1, the new office master 2 and the management room master 3, and an adapter 4 b And a controller second interface (controller second IF) 44 and the like.

The adapter 4b also includes a modulation system conversion unit 51 that re-converts the captured video signal of the camera 12 that has been modulated and transmitted from the new entrance door 1 into a modulation signal used by the old system S2, and the new system S1. A function of converting a communication protocol so that the old system S2 can receive a signal such as a paging signal transmitted from the network, and a function of converting a communication protocol so that the new system S1 can receive a signal transmitted from the old system S2.

The modulation system conversion unit 51 includes a video demodulation circuit 51a that demodulates the transmitted video signal, and a video modulation circuit 51b that remodulates the demodulated video signal to the modulation system used by the old system S2. I have.

  The renewal of the apartment house intercom system configured as described above is performed as follows. First, the old collective entrance machine 61 is removed and the new collective entrance machine 1 is installed. Then, the new controller 4 is installed in the vicinity of the old controller 64, the new collective entrance machine 1 and the new controller 4 are connected by the transmission line L1, and the new controller 4 and the old controller 64 are connected. At this time, the adapter first IF 54 was connected to the controller second IF 44 of the new controller main body 4a via the transmission line L4, and the adapter second IF 55 was connected to the old collective entrance 61 of the old controller 64 via the transmission line L5. It is connected to a terminal (collective entrance connection part) (not shown). Thus, the new controller 4 is connected to the old controller 64, and the old and new systems S1 and S2 are connected.

In this state, the transmission line L2 is arranged from the new control unit 4 to each dwelling unit, and the old and new replacement of the room master unit of each dwelling unit is performed. When the replacement is performed and the new room master 2 and the new controller 4 are connected and communication is possible between them, the controller CPU 42 recognizes this. At this time, the controller CPU 42 obtains the ID information of the new room parent device 4 through communication with the new room parent device 4 and registers it in the FROM 41 in association with the dwelling unit number.
When a call is made from the new collective entrance 1 to the registered new room master 2 by this registration, the controller CPU 42 recognizes that the called dwelling unit has been replaced with the new room master 2 and the old room. The call signal is transmitted to the new room master unit 2 without sending the call signal to the master unit 62. Note that registration control of the new office master 2 by the controller CPU 42 is performed as appropriate, and is performed each time the old office master 62 is replaced with the new office master 2.
Thus, when all the living room master units 2 and 62 and the management room master units 3 and 63 are replaced, the adapter 4b is removed, the old controller 64 is removed, and the renewal is completed.

  Here, the operation of the system when the resident's calling operation is performed from the new collective entrance machine 1 during the renewal will be specifically described. When the operation unit 11 of the new collective entrance machine 1 is operated to input the dwelling unit number to be visited and the call operation is performed, the collective entrance machine CPU 15 sends the call signal converted into data from the collective entrance machine IF 16 to the new controller 4. It transmits to the main body 4a. The call signal is received by the controller first IF 43 of the new controller 4, and the called unit number information included in the call signal is acquired by the controller CPU 42.

  The controller CPU 42 writes the dwell unit number information of the newly connected main unit 2 that is actually connected to the FROM 41 as well as the dwell unit number information of the new unit 2 that will be connected in the future. The called unit number information is determined based on the information in the FROM 41, and it is determined whether it is a unit number that has already been connected to the new room master unit 2 or a unit number that has not yet been connected. If it is connected, a call signal is transmitted from the controller first IF 43 to the new home base unit 2 to make a call, and if it is determined that the call is to a dwelling unit that is not connected, the controller passes through the controller second IF 44. Then, a call signal is transmitted to the adapter 4b.

  Also, the new collective entrance machine 1 on which the call operation has been performed takes an image of a visitor who has been invoked by the camera 12 and the image signal is modulated by a modulation unit (not shown), and the collective entrance machine is similar to the call signal. The data is transmitted from the IF 16 to the main body 4a of the new controller 4. The control unit CPU 42 also transmits this video signal to either the new-room master unit 2 or the adapter 4b in the same manner as the call signal.

  When the controller CPU 42 determines from the information in the FROM 41 that the call is to the new room master unit 2, a call signal is transmitted to the new room base unit 2, a ringing tone is reported from the speaker 23, and a video signal is received. The visitor video is displayed from the monitor 24. When the resident who notices the ringing sound operates the call button 21 to perform a response operation, a response signal is transmitted to the new controller 4 through a path reverse to the call signal. Upon receiving this response signal, the controller CPU 42 forms a communication path between the new collective entrance machine 1 and the called new room master unit 2. Thus, the visitor can make a call with the resident, and the resident can confirm the visitor by video while responding.

On the other hand, if the new room master unit 2 is not yet connected to the call destination dwelling unit and the controller CPU 42 determines that the call is to the old room base unit 62, a call signal is transmitted to the adapter 4b. When the adapter first IF 54 receives this call signal, the adapter CPU 53 converts the call signal into the communication protocol of the old system S2 and transmits it from the adapter second IF 55 to the old controller 64.
In addition, a video signal transmitted from the new collective entrance machine 1 following the calling signal is also transmitted to the adapter 4b. The video signal received by the adapter first IF 54 is re-modulated to a video signal that can be received by the old system S2 in the modulation method conversion unit 51, and is transmitted from the adapter second IF 55 to the old controller 64 in the same manner as the calling signal.

When receiving the call signal and the video signal from the adapter 4b, the old controller 64 transmits the call signal and the video signal from the old collective entrance 61, and transmits them to the caller's old living room master 62. The old room master unit 62 that has received the call signal and the transmission signal reports a call and displays a visitor video from the monitor 62a in the same manner as the new room base unit 2 that has received the call signal.
When the resident who notices the ringing tone operates and responds to the call button 62b, a call path is formed and the visitor can talk to the resident, and the resident responds by visualizing the visitor. It can be confirmed with.

Thus, when the apartment house intercom system is updated, the new controller 4 of the present invention is used as the controller 4 of the new system S1, and the controller 64 and the adapter 4b of the old system S2 are connected to each other. The old master unit 62 can also be called from the new collective entrance 1 of the system S1, and both the new and old systems can be operated in parallel with one collective entrance.
As a result, in the process of updating the system, it is possible to call either the old or new living room parent machine without arranging two new and old entrance doors, and even if the entrance is a narrow apartment house Smooth renewal work without inconvenience to the user. In addition, it is not necessary to post the notice at the entrance each time the parent unit that can be called is changed.
Furthermore, since the communication protocol is converted during communication between the new and old control units, it is possible to call the old home base unit 62 from the new collective entrance 1 even if the communication protocol of the old and new systems is different. The model is not limited.
Further, since the adapter 4b can be easily removed, it can be removed if it is not necessary and can be easily changed. Therefore, the adapter 4b can be exchanged according to the communication protocol of the connection destination system. The cost of the controller 4 can be reduced.
Further, even if the video signal modulation method is different, the visitor captured video can be transmitted to the old system S2. Therefore, a video signal can be transmitted from the new entrance hall 1 to the old room master 62, and video information can be transmitted and displayed in accordance with the calling signal.

In the above-described embodiment, the old system S2 has a configuration in which the camera is provided in the collective entrance 61. However, even if the system having no camera is renewed to the system having the camera, the new controller 4 can be easily applied. Further, even if the system equipped with the camera is renewed, if the modulation method is the same, it is not necessary to provide the modulation method conversion unit 51 in the adapter 4b.
Furthermore, although the adapter 4b is separated from the new controller main body 4a, it may be integrated.
