Here, the entire intercom system will be described first with reference to FIG. This intercom system is composed of housing information panels J1 to Jn and
1 and EP2, an intercom function between the housing information panels J1 to Jn and the management control panels SM1 and SM2, and an abnormality between the housing information panels J1 to Jn and the management control panels SM1 and SM2. It has a processing function. Therefore, the operation of the intercom function between the housing information panels J1 to Jn mainly used and the collective entrance machines EP1 and EP2 will be described first. When the visitor operates, for example, a ten-key (not shown) of the collective entrance machine EP1 to input a room number to be visited, for example, 102, and then presses a call switch (not shown), the call control from the collective entrance machine EP1 via the control line L11. A call signal including a room code and a call code is sent to device TC. Call control device T
When C receives the call signal from the collective entrance machine EP1, it checks for a free call line, and if the second call line is in use, sends a call signal and a call line designation command for the first call line L22 to the control line L.
The information is sent to the house information panel J2 of the room No. 102 via the unit 12.

Further, the house information panel J2 of the room No. 102 is provided with a calling signal received through the control line L12 and the first communication line L22.
In response to the call designation command, each call switch (not shown) is controlled to connect the first call line L22. In addition, a ringing tone is emitted from the speaker SPK, and the lobby light LP2 is turned on. Hereinafter, "hook-on" refers to releasing a hook (not shown) of the board by taking the handset HS from the board of the house information board J2, and "hook-off" means placing the handset HS on the board of the house information board J2. Means to depress a hook (not shown) on the board surface. When the handset HS is picked up by the house information panel J2, a hook (not shown) of the house information panel J2 pressed down by the handset HS is released (hook-on), and the control line L is transmitted from the house information panel J2 to the communication control device TC.
A hook-on signal detected by the hook-on / off detection circuit 13 is sent out via 12. Upon receiving the hook-on signal from the housing information panel J2, the call control device TC sends a call line designation command for the first call line L21 to the collective entrance device EP1, and this command causes the collective entrance device EP1 to switch the call connection switch (not shown). To connect the first communication line L21. As a result, a communication path between the collective entrance machine EP1 and the house information panel J2 is formed, and a call is made between the visitor and the resident of the room No. 102.

If there is an automatic door for entrance at the collective entrance, when an unlock switch (not shown) on the house information panel J2 is operated, an unlock signal is sent to the electric lock of the collective entrance machine EP1 via the control lines L12 and L11. Sent and the automatic door is opened. In addition, the handset HS of the house information panel J2 after the call ends
Is returned to its original state (hook-off), the housing information panel J is detected based on the hook-off signal detected by the hook-on / off detection circuit 13.
2 transmits a call end signal to the call control device TC via the control line L12, and the call control device TC sends an end command to the control line L11. Thereby, the collective entrance machine EP1 opens the connection switch (not shown) of the first communication line L21,
The housing information panel J2 opens a connection switch (not shown) of the first communication line L22. As a result, the first communication line is released.

Next, an outline of the operation of the abnormality processing function between the house information panels J1 to Jn and the management control panels SM1 and SM2 will be described. Hereinafter, one of the housing information boards J1 to Jn
Are indicated by J, and one of the control panels SM1 and SM2 is used.
One is denoted by SM. Here, the abnormal processing refers to disaster processing such as fire, gas leakage, crime prevention, etc., call processing for calls such as baths and toilets, and failure processing such as disconnection of a disaster prevention device, disconnection of a sensor, and transmission abnormality. When performing the abnormality process, when the abnormality detector group UD in each room detects an abnormality, the house information panel J in each room issues an emergency polling request to the management control panel SM. Upon receiving the urgent polling request, the management control panel SM transmits the urgent polling data to the housing information panel J in all rooms.
Send to

The house information panel J of the room in which the abnormality was detected responds with a predetermined time slot following the data of the emergency polling to notify that the abnormality has been detected by the management control panel SM.
Notify. From the time slot, the management control panel SM determines whether an abnormality is a disaster prevention, a call, or a failure, and also determines a floor group. If the floor group is a disaster prevention, for example, the floor polling data of the disaster prevention is transmitted. Send to floor group. If the room of the floor group where the disaster prevention abnormality is located on the third floor, the house information panel J of that room is sent to the management control panel SM by responding with a time slot indicating that it is on the third floor. I do.

The management control panel SM determines from the time slot that it is on the third floor, and sends room polling data to the room group on the third floor. If there is no response from the house information panel J of each room in the room group, room polling data is sent to another room group. When polling the other room groups, for example, when receiving data indicating the room number from room number 10, the control panel SM for management in the management room specifies room number 10 and selects information for collecting information on the content of disaster prevention. Done 1
For example, a fire alarm signal is received from the house information panel J of the room No. 0, the fire is determined, and the room number and the fire are displayed. The above description is for the case of a fire for disaster prevention, but the same applies to gas leaks and crime prevention. Calls and failures other than disaster prevention are also determined in a similar procedure.

Next, the operation of the first embodiment will be described with reference to FIG. 1 and the flowcharts of FIGS. First, the microcomputer 1 of the management control panel SM is connected to each DIP switch DIP in the DIP switch group DIPS provided in the panel.
IP1 to DIP4 are read (step S1).
Next, as described above, when the management control panel SM that has received the urgent polling request receives an alarm signal from the house information panel J that has been polled (step S2), the alarm signal is fire or gas leak. Alternatively, it is determined whether or not the signal is a signal indicating disaster prevention of crime prevention (step S3). If the signal is a signal indicating disaster prevention, the process enters disaster prevention processing (step S4), and returns to a state of receiving the next alarm signal again.

If the alarm signal is not a signal indicating disaster prevention, it is determined whether or not the signal is a signal indicating a call (step S5). If the signal is a signal indicating a call, call processing is started (step S6). ), And returns to the state of receiving the next alarm signal again. Further, if the alarm signal is neither a signal indicating disaster prevention nor a signal indicating a call, it is determined whether or not the signal is a signal indicating a failure (step S5). Enter (step S7), and return to the state of receiving the next alarm signal again.

The foregoing has been described up to the start of each process of disaster prevention, call, and failure. Next, the display / sound process of each process will be described. FIG. 6 shows a specific flowchart of the display / sound processing of the disaster prevention processing. The display / sound processing of this disaster prevention processing is performed first by each DIP switch DIP1 to DIP
Regardless of ON or OFF of 4, for example, a room number process of displaying the room number of the room that has transmitted the fire alarm signal on the room number display section IND1 and lighting and displaying the red fire indicator light LP1 is performed (step S41). . Next, a sound processing for repeatedly sounding a fire alarm sound, for example, "Fire in phone room phone phone phone room No. ○" is performed by the speaker SPR which is a sound generator (step S42). The sound of the alarm sound is stopped when the sound stop switch SW1 is turned on. After a while, the fact that the fire in room # is a fire is notified to the management company (step S43), and the system returns to the state of receiving the next alarm signal again.

FIG. 7 shows a specific flowchart of the display / audio processing of the call processing. In the display / audio processing of the call processing, first, it is determined whether or not the call processing DIP switch DP2 of the read DIP switch group DIPS is turned on (step S61). A room number process of displaying the room number of the room that has transmitted the bus call alarm signal on the room number display section IND1 and lighting and displaying the red call indicator light LP6 is performed (step S62). ○ It is determined whether or not to transfer the presence of a bus call in the room to the management company (step S65). If it is determined that the transfer is to be performed, the presence of the bus call is transmitted to the management company (step S6).
6) Return to the state of receiving the next alarm signal again.

A call processing DIP switch DP2
Is off, after performing the room number process (step S63), a sound process for repeatedly sounding a bus call alarm sound, for example, "an emergency has occurred in the room No. ポ" is performed by the speaker SPR which is a sound generator. (Step S6
5). Note that the sound of this alarm sound is a sound stop switch SW.
When 1 is turned on, it stops. Thereafter, it is determined whether or not to notify the management company that there is a bus or toilet call in the room # (step S65). If it is determined that the transfer is to be performed, the presence of the bus call is transmitted to the management company. (Step S66), and returns to the state of receiving the next alarm signal again.

FIG. 8 shows a specific flowchart of the display / sound processing of the failure processing. The display and sound processing of this failure is performed by first reading out the DIP switch group DIPS
It is determined whether or not the failure processing DIP switch DP3 is turned on (step S71). If it is turned on, for example, the room number of the room which has issued the failure alarm signal of the house information panel J is displayed as the room number. A room number process for displaying on the section IND1 and lighting and displaying the red failure indicator LP7 is performed (step S72), and the process returns to a state for receiving the next alarm signal again. Also, the failure processing DIP switch DP3
Is off, after performing the room number processing (step S73), the alarm sound of the failure of the house information panel J with the speaker SPR which is a sound generator, for example, "the house information panel is broken in room No. 2" Is repeated (step S74), and the process returns to the state of receiving the next alarm signal again. The sound of the alarm sound is stopped when the sound stop switch SW1 is turned on. As described above, the room number display section IND1 is turned on and off according to the on / off state of the call signal DIP switch DP2 and the failure signal DIP switch DP3.
It is possible to select the presence or absence of a call and a failure by displaying a room number on the display and a warning sound of a failure and a failure by sounding a warning sound with the speaker SPR which is a sound generator. Can be easily coped with by setting the call signal DIP switch DP2 and the failure signal DIP switch DP3.

FIG. 9 is a flowchart showing a subroutine of the sound processing of the intercom system. This subroutine of the sound processing is performed so that various alarm sounds are automatically stopped after a predetermined time when the sound automatic stop DIP switch DP4 is turned on when each sound processing of disaster prevention, call and failure processing is performed. The details will be described below. DIP switch group DI which was read first
Among the PSs, it is determined whether or not the DIP switch DP4 for automatic sound stop is turned on (step S81). If the DIP switch DP4 is turned on, a timer 15 built in the microcomputer 1, for example, for 3 minutes is set. (Step S8
2) After that, each sound processing of disaster prevention, call or failure is started, and an alarm is sounded on the management control panel SM (step S83).

Next, it is determined whether or not the timer 15 has timed out after the alarm sound (step S8).
4) When, for example, three minutes have passed since the alarm sound was emitted, the timer 15 times out and stops the alarm sound from being emitted (step S85), and returns to the state of receiving the next alarm signal again. DIP switch DP4 for automatic sound stop
Is off, the alarm sounds continuously until the sound stop switch SW1 is turned on. As described above, by turning on the automatic sound stop DIP switch DP4, when the control room is in an unmanned state, it is useless to hear an alarm sound when displaying a call or a failure and performing sound processing, and there is also a possibility that the residents may be inactive. To prevent suspicion, the warning sound is not sounded for a predetermined time or more.

Embodiment 2 FIG. FIG. 10 is a circuit diagram showing a configuration of a control panel for management of an intercom system according to Embodiment 2 of the present invention, and FIG. 11 is a diagram showing a call process or a failure process corresponding to turning on / off a key in a management room of the intercom system. It is a flowchart which shows a routine. In the second embodiment of the present invention, the microcomputer 1 turns on the key at the entrance of the management room,
The processing of the alarm signal is changed by inputting the OFF signal. Other configurations are the same as those of the embodiment except that the microcomputer 1 does not include the timer 15 and that the DIP switch group DIPS is not provided. Since the configuration is the same as that of the first embodiment, the same reference numerals as those in the first embodiment denote the same components, and a description of the redundant configuration will be omitted. Reference numeral 20 denotes a key at the entrance of the management room.

Next, the operation of the second embodiment of the present invention will be described with reference to FIG.
1 will be described with reference to a flowchart showing a routine of a call process or a failure process corresponding to turning on and off of the key of the management room shown in FIG. The display or sound processing of the call or the failure processing is performed by first checking whether the key is inserted into the key hole of the key 20 at the entrance of the read management room and the key 21 outputs an ON signal (the management room is unmanned). Is determined (step S101),
When the ON signal is output, for example, the housing information panel J
The room number of the room that has issued the alarm signal of the failure is displayed on the room number display section IND1, and the red failure indicator LP
7 is lit and displayed (step S10).
2) Return to the state of receiving the next alarm signal again. Also,
When the key 21 outputs the OFF signal, after performing the room number processing (step S103), the alarm sound of the house information panel J is output from the speaker SPR, which is a sound generator, for example, "the house information is displayed in the room # 2. The sound processing for repeatedly sounding "the board is out of order" is performed (step S104), and the process returns to the state of receiving the next alarm signal again. The sound of the alarm sound is stopped when the sound stop switch SW1 is turned on.

As described above, when the key is inserted into the keyhole at the entrance of the control room and the key 21 outputs an ON signal, the control room is unmanned, and when a call or a failure is displayed and sound processing is performed, an alarm sound is generated. It is no use to sound an alarm because it is useless and the residents are suspicious. In addition,
Although the above description has described the case of a failure of the housing information panel in the failure processing, it also applies to failures other than the failure of the housing information panel, and it also applies to call processing other than failures. Not even. In the disaster prevention processing, not only the display processing but also the sound processing is performed regardless of the ON / OFF signal of the key 21. In the above embodiment, the intercom of the apartment house has been described.
The same applies to the intercom system of a detached house. In the above-described embodiment, an example in which the control panel for management is provided in the management room is shown, but it may be provided in a place other than the management room.

[0033]

As described above, according to the intercom system of the first aspect of the present invention, the microcomputer of the management control panel responds to a call signal such as a bus call or a toilet call from the house information panel. When the call signal DIP switch is turned on, a call is displayed on the display means,
The sound generator does not sound the call alarm, but when it is off, the call is displayed on the display means, the sound generator controls the sound of the call, and the fire alarm from the housing information panel and the sensor break. When the failure signal DIP switch is turned on, a failure signal is displayed on the display means for a failure signal such as a transmission error, but a failure alarm is not sounded by the sound generator. When the failure signal is off, the failure means is displayed on the display means. The sound generator also generates an alarm sound of a failure, so that the call and display of the display means and the failure display and the call and failure of the sound generator are performed according to ON / OFF of the call signal DIP switch and the failure signal DIP switch. Can be selected whether or not there is an alarm sound.
There is an effect that it can be easily handled by setting the P switch.

According to the intercom system of the second aspect of the present invention, when the DIP switch for automatic sound stop is turned on at the stage of sound processing, the microcomputer of the control panel controls the sound of the sound generator for a predetermined period. When the sound stops, the sound is automatically stopped regardless of the sound stop switch. When the sound is turned off, the sound generator is controlled to sound the sound until the sound stop switch is turned on. When the control room is unmanned by turning on the switch, it is useless to sound an alarm when displaying a call or failure and performing sound processing. There is an effect that can be done.

According to the intercom apparatus of the third aspect of the present invention, when the key of the control room outputs the ON signal at the stage of the call or the failure processing, the microcomputer of the control panel for control outputs the signal from the house information panel. In response to a call signal such as a bus call, a toilet call, or a failure signal such as a disconnection of a disaster prevention device, a disconnection of a sensor, a transmission error, etc., a call is displayed on the display means based on a key ON signal. Without ringing
When the control room key is outputting an off signal, the call is displayed on the display means based on the key off signal, and the sound generator is controlled to sound a call alarm, so the control room key is turned on. If the control room that outputs the warning message is unattended, it is useless to sound an alarm when displaying a call or a failure or performing sound processing. There is an effect that can be.
