DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a telephone system for an apartment complex.

[Background technology]

Figure 1 shows a basic block diagram of a telephone system for an apartment complex. In the figure, 1 is an alarm monitoring panel that is a central calling device installed in a manager's room, etc. This alarm monitoring panel 1 is installed in each dwelling unit. The residential unit terminals 2... are connected to a lobby operation panel 3, which is a central calling device provided in the entrance lobby, via a power line carrier signal line 1 using a low voltage power line, and this alarm monitoring panel 1
transmits a signal over the power line carrier, receives an answerback signal in response to the transmitted signal, and also receives a transmitted signal and an answerback signal transmitted from the dwelling unit terminal 2 or the lobby operation panel 3, and the transmitted signal If the signal is for the address of It is now possible to monitor alarm inputs such as: On the other hand, the lobby operation panel 3 transmits a signal via the power line carrier, receives an answerback signal in response to the transmitted signal, and also receives a transmission signal and an answerback signal transmitted from each dwelling unit terminal 2 or alarm monitoring panel 1. It is equipped with logical operation control means and is adapted to communicate with the intercom of each dwelling unit and the intercom of the alarm monitoring panel 1. The dwelling unit terminal 2 transmits the above-mentioned alarm input status via power line carrier, and also receives signals sent from the alarm monitoring panel 1 and each dwelling unit terminal 2, and if the signal is for its own address, it sends the signal to the telephone line and intercom. It is equipped with a logic operation control means that controls the built-in relay for connecting the unit and sends an answer backup signal, and is capable of sending alarm input from the housing unit information panel.
The intercom call line is now connected.

By the way, in such a system, the alarm monitoring panel 1 and the lobby operation panel 3 have a correspondence table between the housing unit number of each housing unit and the unique address of each housing unit terminal 2, but the presence or absence of the housing unit terminal 2 is determined by the system. Therefore, when the system is powered on, the alarm monitoring panel 1 sends an off signal to all residential unit terminals 2 via power line transmission based on a correspondence table that is set and stored in advance. The alarm monitoring panel 1 And the lobby operation panel 3 creates a new address correspondence table for the residential unit terminals 2 connected to the system. This series of operations is called initialization, and by this initialization, even if an attempt is made to call the intercom of a dwelling unit with an address that does not exist on the system from the alarm monitoring panel 1 or lobby operation panel 3, the alarm monitoring panel 1 and lobby operation will not be activated. Panel 3 is designed not to process calls. By the way, the above-mentioned initialization is a cold start that is performed every time the system power is turned on or whenever the CPU, which is the logic operation control means, is reset due to noise, etc., and a hot start that is performed when a momentary power outage occurs on that board. However, in the case of conventional cold start, first, the alarm monitoring panel 1 sequentially transmits an off signal to turn off the connection of the intercom to the telephone line to the dwelling unit terminals 2 of all unique addresses,
When an answer call signal is returned from the residential unit terminal 2 in response to this transmission, the corresponding address is registered in the correspondence table on the memory, using the residential unit terminal 2 as the residential unit terminal in use. At the same time, the answer call signal is also received by the lobby operation panel 3, and in response to the answer call signal, the address of the dwelling unit terminal 2 is stored in the correspondence table in the memory of the lobby operation panel 3. Register it in the same way as for board 1.

By the way, with this method, if only the lobby operation panel 3 side is cold-started, the correspondence table of the lobby operation panel 3 will only be cleared, and the alarm monitoring panel 1 side will only be cleared.
Since the initialization is not performed again, there is a drawback that it becomes impossible to call the residence from the lobby operation panel 3, and it becomes impossible to make a call using the intercom.

The reason why an off signal is sent to disconnect the intercom from the telephone line during initialization is because a latching relay is used to connect the telephone line and the intercom. held or
Alternatively, the switch may change from the off state to the on state due to an external mechanical shock during transportation.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned problems, and its purpose is to provide a central calling device that calls all residential unit terminals with unique addresses when initializing the registration of a residential unit address. , a telephone system for an apartment complex in which an initial request signal is sent to the main central paging device when only the secondary central paging device cold-starts, so that the main central paging device always starts an initializing operation. is to provide.

[Disclosure of the invention] The present invention will be explained below based on examples.

Figure 2 shows the circuit diagram of this system. The lobby operation panel 3 installed in the entrance lobby has an intercom 4 equipped with a handset, a display section 5 that displays key input, and an electric lock for unlocking the entrance door. An electric lock unlocking section 6 for locking, a key input section 7 for inputting a housing number or a password, logic circuit sections 8 and 9 as logic operation control means, and a connection control section 11 for connecting the intercom 4 to the telephone line 10. and a modulation/demodulation section 12 that transmits a call signal formed by the logic circuit section 8 based on the key-input dwelling unit number and receives a call signal for the lobby operation panel 2, and a constant voltage circuit section 13. has been done. The alarm monitoring panel 1 installed in the control room has an intercom 14 and a display/operation unit 15 for displaying alarm input, calling the residence or entrance lobby, and unlocking the electric lock.
, an electric lock unlocking output section 16 , an alarm buzzer 17 that notifies input of abnormality information, logic circuit sections 18 and 19 serving as logic operation control means, and a transfer contact output section 20
, a connection control section 21 , a modulation/demodulation section 22 , a constant voltage circuit section 23 , a block filter 24 , a power transformer 25 , and a power filter 26 . The dwelling unit terminal 2 provided in each dwelling unit is formed by adding a dwelling unit information panel 33 having an intercom 38 and various sensors, and an entrance device 34 consisting of an intercom slave device disposed at the entrance of the dwelling unit,
The residential unit terminal 2 includes a modem section 27 and a logic circuit section 2.
8, address setting section 29, and monitoring input section 30
, a connection control section 31 , and a power supply section 35 . 32 in the diagram is the unlock button that unlocks the entrance door, 3
6 is an unlocking signal line that transmits an unlocking signal. Further, 37 is a switch provided on the alarm monitoring panel 1 for interrupting initialization.

When the system is started, the alarm monitoring panel 1, which is the main central calling device, operates according to the main flow shown in FIG. 3, and the lobby operation panel 3 operates according to the main flow shown in FIG. .
In other words, when the system is started, the alarm monitoring panel 1 performs initialization processing to create a correspondence table between each dwelling unit number and the dwelling unit terminal 2, and after completing this initialization processing, key input and display processing on the display operation section 15 are performed. , it is in a standby state for call processing by the intercom and alarm input processing by transmission from the dwelling unit terminal device 2. On the other hand, the lobby operation panel 3, which is a secondary central calling device, enters a standby state for key input and display processing at the display section 5 and key input section 7 and call processing at the intercom after the system is started. Well now,
When the system is started, the operations of the logic circuit sections 18 and 19 of the alarm monitoring panel 1 jump to the initialization routine flow shown in FIG. 5, and initialization processing is first performed. In the initialization process, it is determined whether the power is turned on after a long-term power outage, a cold start is performed by resetting the logic circuit units 18 and 19 comprising the CPU, or a hot start is performed by a momentary power outage. Of course, when the system is started up, it is a cold start, so the logic circuit sections 18 and 19 of the alarm monitoring panel 1 transmit the initial start signal together with the address data of the lobby controller 3 via the power line carrier signal line l. Transmit. This initial start signal is a signal for initializing the contents of the correspondence table in the memory, which is provided on the lobby operation panel 3 and registers the correspondence of the addresses of the residential unit terminals 2 in use. Now, the logic circuit sections 18 and 19 of the alarm monitoring panel 1 sequentially access all the unique addresses used in the system from the first address to the last address, and check whether or not an answer back signal is returned each time each unique address is accessed. It is to judge. In other words, the alarm monitoring panel 1 transmits an off signal to turn off the built-in relay of the connection control unit 31 of each dwelling unit terminal 2 and disconnect the intercom 38 together with the address data via the power line. It accesses the address. When the residential unit terminal 2 connected to the signal line 1 calls its own address, it receives the off control signal, disconnects the intercom 38 from the telephone line 10, and returns an answer call signal. If the dwelling unit terminal 2 at the address is not connected, naturally the answer call signal will not be returned. In the alarm monitoring panel 1, the logic circuits 19 and 18 determine the presence or absence of an answerback signal, and if there is an answerback signal, the address of the dwelling unit terminal 2 corresponding to the address is written in the correspondence table on the memory. register. Furthermore, if there is no answer back signal, the address of the dwelling unit terminal 2 corresponding to the address will not be registered in the correspondence table. After the above-mentioned determination, the logic circuit section 18 determines whether the switch 37 for interrupting the initialization has been turned on, and determines whether there is a request to end the initialization. If the switch 37 is not turned on here, it is determined whether or not the calling of the dwelling unit terminals 2 corresponding to all addresses has been completed, and if "NO", the process returns to the above-mentioned calling of the dwelling unit terminals 2 and the correspondence table. Each registration operation is repeated until the switch 37 is turned on or until all the addresses have been called by the dwelling unit terminals 2. The switch 37 may need to be turned on and off many times during maintenance and inspection, or the system may be small and it may take too long to finish calling the residential unit terminals 2 for all addresses. This is a switch that can interrupt the initialization process, and when this switch 37 is turned on or calls to the residential unit terminals 2 of all addresses are completed, the alarm monitoring panel 1 transmits the initialization completion signal via the power line. The data is transmitted via the signal line 1, and the process moves on to other processing in the main flow. By the way, if the above hot start determination is "YES", the signal line l
It is determined whether or not the initial request signal is being transmitted from the lobby operation panel 3 via the power line transport. If "YES", the above-mentioned initial start signal is transmitted; if "NO", the main It moves on to other processing in the flow. On the other hand, the logic circuit units 8 and 9 of the lobby operation panel 3 determine whether or not the power is turned on by a hot start, depending on whether the power is turned on due to a momentary power outage. Here, the lobby operation panel 3 is powered on after a long-term power outage, or the logic circuit section 8 consisting of the CPU,
9, the logic circuit section 8 determines whether the reset has occurred based on the function of the power-on detection means or the reset detection means.
Alternatively, if the determination is made based on the detection of the activation of the initial request switch, that is, if it is determined that a cold start has occurred, the logic circuit section 9 transmits the initial request signal to the alarm monitoring panel 1 via the power line. When the alarm monitoring panel 1 has not performed a cold start, the alarm monitoring panel 1 receives this initial request signal and transmits an initial start signal. On the other hand, if the alarm monitoring panel 1 is in a cold start state like the lobby operation panel 3, the initial start signal is transmitted regardless of the transmission of the initial request signal from the lobby operation panel 3. Now, after transmitting the above-mentioned initial request signal, when an initial start signal is transmitted from the alarm monitoring panel 1 and received by the lobby operation panel 3, a signal is sent from the dwelling unit terminal 2 called by the alarm monitoring panel 1 on the signal line l. The presence or absence of the answer back signal is determined by determining whether or not the answer back signal is superimposed. If there is an answer back signal, it is assumed that the dwelling unit terminal 2 at the address is connected to the system, and the address is written and registered in the correspondence table on the memory. If there is no answer back signal, it is determined that the dwelling unit terminal 2 at the address is not connected, and no registration is performed. Then, it is determined whether or not the initial end signal is being transmitted from the alarm monitoring panel 1, and the answer is "NO".
If so, the above-mentioned determination of reception of the answer back signal is made, and if it is ``YES'', the process is shifted to other processing. Also, the above hot start judgment is “YES”.
If so, the lobby controller 3 determines whether or not an initial start signal is received from the alarm monitoring panel 1, and if it is received, it determines whether or not the above-mentioned answer back signal is received, and then returns the above-mentioned address. Registration is performed, and if there is no reception, the process moves on to other processing. As described above, each logic circuit section 8, 9, 18, 1
9 functions as an initializing means, and the address registration function uses the built-in memory, respectively.

Next, the operation after initialization will be explained. Now, the visitor is entering the key input section 7 of the lobby operation panel 3.
When the residential unit number of the destination is input, a calling signal that transmits the address data for calling the residential unit 2 of that residential unit number is generated in the logic circuit units 14 and 15, and is sent to the power line carrier signal line via the modulation/demodulation unit 12. sent to l. This call signal is transmitted through the power line carrier signal line l.
It is received and demodulated by the modulation/demodulation section 27 of each residential unit terminal 2 via the terminal 2, and the logic circuit section 28 determines whether the address set by the address setting section 29 matches the address data based on the calling signal, and an address match is obtained. When the connection control unit 31 is activated and the connection control contact is turned on, the intercom 38 connects to the call line 1.
0, and the connection control contact is turned on in the connection control unit 11 of the lobby operation panel 3, and the intercom 4 of the lobby operation panel 3 and the intercom 4 of the dwelling unit terminal 2 are connected via the telephone line 10, and an intercom call is made. will be carried out. When the resident of the dwelling unit approves the visit of a visitor, he operates the unlock button 32 and sends an unlock signal for the entrance door to the unlock signal line 36. When the lobby operation panel 3 receives the unlocking signal, it outputs an unlocking output signal for unlocking the electric lock of the entrance door from the electric lock unlocking section 6 for a certain period of time, and automatically opens and closes the entrance door.
Next, when the resident opens the front door when returning home, he or she enters a predetermined password using the key input section 7, and the logic circuit section 8 checks whether the password matches. The electric lock will be unlocked. Note that the operation is similar to the above-described operation when calling the alarm monitoring panel 1 provided in the management room from the lobby operation panel 3 and talking to the manager via intercom, or when unlocking from the management room. On the other hand, when calling the dwelling unit terminal 2 from the alarm monitoring panel 1 and making an intercom call, the dwelling unit number is input using the input keys of the display operation section 15, and the logic circuit sections 18 and 19 send a call signal in the same manner as described above. In addition, when calling the alarm monitoring panel 1 from the dwelling unit terminal 2 to make an intercom call, a control room call button (not shown) provided on the dwelling unit information panel 33 of the dwelling unit terminal 2 may be used. 1) to cause the logic circuit section 28 to generate a calling signal.

On the other hand, alarm inputs caused by activation of fire sensors, gas leak sensors, emergency call switches, etc. in each dwelling unit are output as contact signals from the dwelling unit information panel 33, and are sent to the logic circuit via the monitoring input section 30 of the dwelling unit terminal 2. The alarm input signal is inputted to the section 28 to form an alarm input signal in a predetermined format, and is sent to the power line carrier signal line l via the modulation/demodulation section 27. Then, in the alarm monitoring panel 2, this abnormality information signal is transmitted to the modulation/demodulation section 22.
The logic circuit sections 18 and 19 identify abnormality information and display it on the display operation section 15, and drive the transfer contact output section 20 to output the alarm buzzer 1.
7 is sounded to notify the occurrence of an abnormality. Note that the ringing signal, alarm input signal, initial request signal, initial start signal, and answer back signal are time division multiplexed signals in which each bit is transmitted in synchronization with the commercial power supply. Transmission is now done using a power line carrier method that superimposes a high-frequency signal on a power source and transmits it.
