BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a residential information system in which a security unit having a function of monitoring fire, gas leakage, theft and the like and a telephone controller having a function as a private branch exchange are combined.

[0002]

2. Description of the Related Art With the spread of parent and child telephones, cordless telephones, and facsimiles, it is becoming common to install telephones in each room of a dwelling unit. When a plurality of telephone devices are installed in this way, a private branch exchange (PBX) is installed for residential use so that the plurality of telephone devices and intercom can be used efficiently without adding a telephone line. From the viewpoint of security, the usage pattern of the telephone device in such a dwelling unit can be considered to be, for example, an extension telephone or an intercom installed in each room can be used as a means for transmitting an alarm when an abnormality occurs.

In view of such a situation, a telephone controller having a function as a private branch exchange (PBX) is added to a system having a conventional security function so that the security system can be integrated with the telephone / doorphone system. Housing information systems are being considered. For example, a security unit that monitors a fire, gas leak, theft, etc. with a security sensor has a function of outputting the content of abnormality as visual or auditory information by detecting an abnormality of the sensor, and is used as a private branch exchange (PBX) in a house. A telephone controller with functions can be provided with the function to connect the outside signal to the extension telephone and the intercom to the extension telephone and the intercom to the extension telephone and the intercom in addition to the communication function between the extension telephone and the intercom. Is.

[0004]

By the way, in this type of home information system, when the security sensor detects an abnormality, the extension telephone emits an alarm ringing sound and the doorphone also emits an alarming sound by the alarm operation of the security unit. If it is issued and it is not a true abnormality and you want to stop the alarm, you can stop the alarm by operating the alarm stop switch provided in the security unit after the confirmation action if the householder is at home. However, if the home is absent due to going out, for example, the security unit equipped with this alarm stop switch is usually installed at a specific location inside the living room or other area, so an alarm should not be issued. If there is no way to externally stop the alarm if it is not due to a true anomaly, especially the door A long time of sounding of the alarm sound from the down has been a giving trouble to the neighborhood.

In order to stop the alarm in such a case, for example, a so-called hidden switch may be provided in the doorphone or in the vicinity thereof to stop the alarm. However, this is considered to be the function when considered as a security system. It is essentially a counter measure.

A main object of the present invention is to provide a house information system comprising a combination of a security unit and a telephone controller so that a specific operator such as a manager can perform an alarm stop operation by an outside line telephone. To provide a system.

[0007]

A housing information system according to the present invention comprises a combination of a security unit and a telephone controller, and the security unit abnormally detects visual and / or auditory information according to an abnormal content by detecting an abnormality of a security sensor. It has a function of outputting as a signal. Further, the telephone controller has a call function between an outside line, an extension line telephone, and an intercom, and when the security unit produces an abnormal signal, it connects the abnormal signal output system of the security unit with the extension line telephone and the intercom. It has a private branch exchange.

In such a house information system, particularly in the house information system according to the present invention, in order to achieve the main object, the telephone controller is provided when the telephone controller receives an abnormal signal from the security unit. Control to activate the automatic incoming call circuit of the outside line in the inside to enter the automatic receiving mode, and when the call from the outside line is made thereafter, perform the automatic incoming call operation to connect the abnormal signal output system of the security unit to the outside line side. Means and an alarm stop control means for outputting an alarm stop signal to the security unit to stop the output of an abnormal signal of the security unit when receiving a predetermined control signal from the outside line after the incoming call operation. It is provided.

[0009]

In the housing information system of the present invention, a fire,
A security unit that monitors gas leaks and theft,
We are constructing a housing information system that fuses with a PBX telephone system that has a selective outside line automatic call reception function and extension exchange function, and detects abnormalities by various security sensors such as fire detectors and gas detectors and activates emergency push button switches. In addition to sounding an alarm sound from the intercom based on the alarm unit's alerting operation, the extension telephone is called with an unusual ringing tone and a voice message is sent from the off-hook telephone of the extension telephone according to the abnormality. It is also possible to fuse so as to output, and in this case, if the extension telephone is in a call, it is also possible to interrupt a voice message indicating abnormality detection in the call line.

Particularly, in the housing information system of the present invention, the control means switches the external telephone automatic incoming call circuit in the telephone controller to the automatic incoming call mode based on the alarming operation of the security unit. When the security unit outputs an abnormal signal due to a warning, the outside line telephone automatic incoming circuit becomes ready for automatic incoming calls, and when there is a call from the outside line, the automatic incoming circuit of the telephone controller receives this and performs the incoming call operation. Then, the control means connects the abnormal signal output system of the security unit to the outside line side, so that a message corresponding to the abnormal signal from the security unit occurring at that time is sent to the outside line.

Further, when the alarm stop control means receives a control signal having a predetermined content such as a push button signal from an outside line which is in a connected state by the operation of the automatic incoming circuit, the security unit outputs an abnormal signal. It has the function to stop.

Specifically, the control means and the alarm stop control means can be constituted by a control circuit including a central processing unit of an internal microcomputer for controlling the operation of the telephone controller and the security unit. When the security unit generates an abnormal signal, the automatic incoming circuit is activated and the system is set to the automatic incoming mode, and when there is a call from the outside line after sono, the automatic incoming operation is performed to notify the abnormal signal of the security unit. The output system is connected to the outside line, and when the alarm stop control means receives a specific control signal from the outside line, it outputs an alarm stop signal to stop the abnormal signal output of the security unit, which causes the extension telephone and the intercom to ring. Performs a series of control operations that are stopped by a specific control signal from the outside line.

That is, in a normal time when the security unit does not generate an abnormal signal, the automatic call receiving circuit is in a non-operating state unless the householder switches to the answering machine mode, and the call from the outside line telephone is selected by the master telephone or the switching. Received by the extension telephone.

On the other hand, the detection of the abnormality by the security sensor is detected by the security unit, and the alarm due to the detection is received by the central control unit such as the manager's room, and the alarm sound of the intercom and each extension telephone and the extension telephone are off-hook. In this case, an alarm message is sent out as usual, but at this time, the control means activates the automatic call receiving circuit in the telephone controller by the output of the abnormal signal of the security unit, and the input / output port for the outside line of the system Establish.

In this way, when the security unit outputs an abnormal signal, the automatic call receiving circuit is activated in the telephone controller, and a call from the outside line is received by the automatic receiving circuit, and the abnormal signal of the security unit is sent to this outside line. The output system is ready to send a message signal or the like.

[0016] Here, when the security unit generates an abnormal signal, an alarm sound is generated from an intercom or the like. If this is a false alarm, if the householder is at home, the cause is confirmed and an alarm is issued on the security unit. The stop operation should be performed.

On the other hand, when the system generates an alarm in an absent house, the manager in the apartment house confirms this, and if there is a true abnormality, reports it to the fire department or the police and takes corrective action. In this case, it is common to take action to turn off the alarm of the door phone that continues to ring. According to the present invention, this can be dealt with by the alarm person performing an alarm stop operation by confirming the absence of an abnormality in the site and then calling the alarm home by an outside line with a telephone in the neighborhood or the control room. is there.

That is, when the security unit outputs an abnormal signal, the control means activates the automatic call receiving circuit to put the system in the automatic call receiving mode. Therefore, when a call from an outside line is received, the automatic call receiving operation is performed and the security unit is operated. The abnormal signal output system of is connected to the external line side, the abnormal content according to the type of the security sensor that is issuing is sent to the external line by a voice message, and the control signal of a specific code number is given from the external line telephone to the system. As a result, the alarm stop control means stops the abnormal signal output of the security unit to stop the ringing of the extension telephone and the intercom, and then opens and restores the telephone line. The control signal based on these specific code numbers is, for example, "9" by the push button of the telephone dial that only a specific operator such as a manager knows.
99 ”or the like may be used.

In the house information system of the present invention, even if the alarm stop switch is present only in the security unit installed in the home such as the living room, the alarm is issued from the outside line telephone without invading the home. It is possible to stop the operation by using the telephone number of the individual dwelling unit and the specific recitation number for the alarm stop operation. Since it is possible to quickly stop the operation of various alarm sounds, it is possible to minimize the annoyance to the neighborhood.

It is sent to the telephone side via 05.

In order to connect the CPU 200 to other devices, the interface 210 for the central control unit, the interface 211 for the security unit, the interface 212 for the television monitor, the sound output unit 214, the doorphone call detection unit 215a, the doorphone call unit 215b, the crime prevention function. A sensor interface 216, a sound interface 218 for receiving a voice message signal from the security unit 10, and the like are provided. Incidentally, 220 is a power supply unit.

Next, the operation of the above embodiment will be described. FIG. 6 is a flow chart showing the system operation when a smoke is detected by the smoke sensor 11 as a fire sensor. 10, the telephone controller 20, and the control room master unit 50 are shown separately for mutual processing.

First, when the smoke detector 11 detects a fire, the fire receiving portion 112 of the security unit 10 receives the fire detection signal, and a fire lamp, that is, the display portion 17 of FIG.
The fire indicator light 101 is turned on. Subsequently, "Woo Woo Fire Occurrence" indicating a fire is output from the speaker 118, and at the same time, the security unit 10 sends a fire signal and a warning voice message signal to the telephone controller 20. Further, the security unit 10 activates the relay A and switches the contact point a to output a voice message from the speaker of the intercom subunit 14.

The interface 211 receives the fire signal and the warning voice message signal from the security unit 10.
And the telephone controller 20 received from the audio interface 218 sends the received fire signal to the control room master unit 50 via the interface 210. When the fire signal is received from the telephone controller 20, the control room master unit 50 turns on the fire lamp corresponding to the reported dwelling unit, sounds a fire alarm sound, and outputs a voice message.

In the telephone controller 20 which receives the fire signal from the security unit 10, the master CPU 2
00 to send a control signal to operate the automatic incoming circuit 209 to enter the automatic incoming mode. In this case, the alarm 118 of the security unit 10 in the reported dwelling unit causes the speaker 118, the intercom slave 14, and the external speaker 25.
Is outputting an alarm sound and a voice message, and an alarm is also generated in the control room base unit 50.

Further, the telephone controller 20 is a master C.
Under the control of the PU 200, it is checked whether or not the extension telephone is in use, and if it is not in use, a ringing tone at the time of a fire alarm as shown in FIG. Whether or not the extension telephone is in use is determined based on the presence / absence of an off-hook signal of the extension telephone in the call control / detection unit 205.

When the call control / detection unit 205 detects that the extension telephone is in use, that is, off-hook, the alarm voice message signal received from the security unit 10 is interrupted by the extension telephone that is off-hook, and the user is forced to do so. The warning voice message “Woo Woo Fire” is transmitted. When the extension telephone receives the alert ringing tone and goes off-hook, an alarm voice message is output to the extension-hooked off-line telephone as in the case of being in use.
In this case, the fire display and the output of the warning voice message in each unit are repeatedly performed until the security unit 10 stops the warning.

Therefore, the manager checks the alarm in the master unit 50 of the management room, goes to the alarm unit, and checks whether there is any abnormality.
If there is no abnormality, the administrator calls the alarm unit from the outside line telephone, but at this time, since the automatic call receiving circuit 209 is already in the automatic call receiving mode, the master CPU 200 detects when the automatic receiving circuit 209 answers the outside line call. An alarm voice message is sent to an outside line via the acoustic signal generator 208 and the call control detector 205.

The manager listens to the warning voice message on the outside line telephone and then performs an operation for stopping the warning. That is, when a predetermined push button PB signal is sent to the telephone controller 20 by the push button operation of the outside line telephone, the outside line PB signal detection unit 203 in the telephone controller 20 detects this and the master CP is detected.
If the U200 judges this and matches with the correct code number, it gives an alarm stop signal to the CPU 111 of the security unit 10 and a control signal for opening the line to the automatic incoming circuit 209. As a result, the alarm in the alarming dwelling unit is stopped, the outside line is also opened, and the alarm in the control room master unit 50 is also stopped.

In the above operation, an answer back confirmation system is used for transmitting the fire signal from the security unit 10 to the telephone controller 20. That is, when the telephone controller 20 normally receives the fire signal, the telephone controller 20 returns the confirmation response signal to the security unit 10. If the confirmation response signal is not obtained from the telephone controller 20, the security unit 1
0 sends the fire signal again.

The above operation example is the security unit 10.
Although the fire detection by the smoke sensor 11 connected to is taken as an example, the detection signals of the gas detector 12, the emergency push button switch 13 and the crime prevention sensors 26, 27 are the same except that the contents of the warning voice message are different. The same is done.

[0051]

As described above, according to the present invention, in a residential information system in which a security function and a private branch exchange function are integrated, it is possible to perform an alarm stop operation by an external telephone without the need to additionally install an alarm stop switch outside the dwelling unit. Even if the family member is away, the alarm can be stopped by the manager by operating the outside line telephone, and it is possible to minimize the nuisance in the neighborhood due to the alarm ringing continuously.
