Description

[Detailed description of the invention] The present invention relates to a button telephone device.

In today's world where technology is rapidly progressing, there is a demand for this type of button telephone device to not only be electronic but also highly functional.

It is well known that conventional key telephone devices of this kind have functions such as calling to a central line, receiving a call to a central line, holding a call, transferring a call, calling to a central line, calling an extension, and communicating between internal lines. In addition to these functions, there is no button telephone device that has functions of a different dimension, such as an emergency alarm monitoring function that is always activated without any restrictions in response to the occurrence of an emergency situation.

As conventional emergency warning monitoring systems that perform constant monitoring, large-scale systems such as wide-area monitoring systems that monitor entire areas and building monitoring systems that monitor entire buildings are known, but In small-scale systems such as homes, small offices, and shops, there are only a few systems that use simple emergency alarm devices, intercoms, or parent-child telephone systems; There are various restrictions on monitoring.

However, in the case of such telephones that use intercoms or parent-child telephones, there is no connection to the central office line, so an emergency alarm device is installed outside the regular telephone or button telephone device. . For example, in a system that uses an intercom, separate devices such as an intercom device and an alarm device are combined and used completely separately from ordinary telephones, etc., and from an economical point of view. Not only was it defective, but it was also extremely inconvenient to use. Furthermore, if we look at the parent-child phone system, there is no connection to the central office line, and it is used completely separately from a normal telephone, etc., and various alarm monitoring functions can only be monitored by the parent phone. There are various limitations, such as the content of monitoring is limited and the system cannot be monitored at all by slave devices. Further, although it is a button telephone device as in Japanese Patent Publication No. 61-6592, there is a restriction that alarm information cannot be sent if the line (line or extension) is not available. This has the fatal disadvantage of delaying response to emergencies, causing greater damage, and potentially leading to major accidents.

In other words, in cases where emergency monitoring can only be performed in one place or where there are various restrictions on monitoring, such as with conventional devices, even if a supervisor is present at all times in the room or location, it may be difficult to monitor the situation in an ordinary home, etc. If there are various restrictions, such as when the rooms are not fixed or when the line is not available, there is a situation where no one can take any action even in an emergency situation.

Furthermore, if we focus on the control function and operation method of an electric lock provided on an entrance door, etc., we cannot find any conventional button telephone device or the like that is equipped with such a function.

In other words, when attempting to monitor crime by installing an electric lock on the entrance door, etc., if the means for controlling the opening and closing of the electric lock is installed only near the door, it would be necessary to go to the door every time a member of the residence returns home. It's very troublesome because you have to go there and release it before opening the door.

Therefore, if a button telephone is equipped with such an opening/closing control means, it will be possible to remotely control opening and closing from the location where the key telephone is installed while communicating with the person returning home via the doorbell. Problems can be resolved.

However, simply providing a key telephone with an electric lock opening/closing control means causes the following problems.

In other words, since the location where a key telephone equipped with an opening/closing control means is installed and, for example, the entrance where an electric lock is installed, are usually far apart and cannot be seen, it is not possible to know whether the door is open or closed at the location where the key telephone is installed. I can't. Therefore, the operation of the opening/closing control means and the timing of opening/closing the door are determined by the "feel" of the operator. For example, if the opening/closing operation by the operator is short, the door may open or close even before or after the door is opened. If the electric lock cannot be closed, the monitoring function of the electric lock will be activated and an alarm will be emitted, and conversely, if the operator continues to operate the lock for too long, there may be a blank period during which the monitoring function cannot function properly. . In other words, a problem arises in that it is extremely difficult for the operator to operate the opening/closing control means and time the opening/closing of the door.

The present invention has been made to eliminate such drawbacks, and its first purpose is to provide an emergency alarm function that is always activated without any restrictions once a monitoring system is put in place in response to the occurrence of an emergency situation. Another object of the present invention is to provide a completely new and highly functional button telephone device.

The second purpose is to make the extension calling means and extension display means (audible and visible) of the button telephone device double as an alarm sending means and an alarm display means (audible and visible) to perform the emergency alarm function. transformation,
An object of the present invention is to provide a button telephone device that is miniaturized and has improved usability.

In addition, the third purpose is to configure the button telephone to perform an emergency warning function (audible, visible), and to display the location of the abnormality and the nature of the abnormality (crime prevention, disaster prevention, etc.) on a predetermined button telephone. It is an object of the present invention to provide a button telephone device configured as described above so that countermeasures against an abnormal situation can be taken immediately.

Furthermore, the fourth purpose is to install an electric lock on the entrance door, etc., to perform security monitoring, and to equip a button telephone with means for controlling the opening and closing of the electric lock, so that the opening and closing of the electric lock can be controlled remotely. An object of the present invention is to provide a button telephone device in which control operability is improved in this manner.

Furthermore, the fifth purpose is to install an electric lock on the entrance door, etc., to perform crime prevention monitoring, and to remotely control the opening and closing of the electric lock by equipping a button telephone with means for controlling the opening and closing of the electric lock. In doing so, each key telephone or a predetermined key telephone is equipped with a visual display means for displaying the opening/closing status of the door, so that the opening/closing control operation of the electric lock can be performed while monitoring the opening/closing status of the door. An object of the present invention is to provide a button telephone device configured as follows.

The main unit is connected to a central office line, and a plurality of button telephones each have a visual display means and an audible display means for at least visual and audible display based on central office line or extension calling information, and have a central office line or extension calling function. In the button telephone device, a predetermined button telephone among the plurality of button telephones or the main device has a detection output from a sensor that detects an abnormal state such as a fire or an open state of a door etc. and an alarm means for transmitting alarm information for visual display and audible display to the plurality of button telephones based on the operation of the reception means, In this case, the visual display means and the audible display means provided in advance are combined to display a visual and audible alarm display different from the visual and audible display based on the central line or extension call information based on the output of the alarm means. In addition, at least one of the plurality of key telephones is configured to be alerted to an abnormal state such as a fire in response to alarm information sent via the receiving means or alarm means. and a second visual display means for visually displaying the location indicating the open state of the door, etc. and the type of abnormality, and the contents of the abnormal state are displayed, and the electric lock provided on the door, etc. It is characterized by being equipped with an electric lock control means for controlling opening and closing, configured to give priority to the alarm display over the visual and audible display based on the office line or extension call information, and having various other monitoring functions. The present invention provides a button telephone device having a comprehensive emergency alarm monitoring function.

Calls such as calling from a central office, receiving a call from a central office, holding, transferring,
Functional operations and means for telephone calls, extension calls, inter-extension calls, etc. have been known for a long time (e.g., Japanese Patent Publication No. 49-89523, Utility Model Publication No. 55-9102, etc.).
A detailed explanation will be omitted hereafter.

Next, the functions, operations, circuit configuration, etc. constituting the present invention will be described using an embodiment of FIG. 2a.

First, the emergency alarm monitoring function will be explained.

Various sensors 10, emergency buttons 7, and emergency bells 8 are installed in various places in advance as described above, and
It is connected to the receiving circuit 24 via the TB terminal 26.

Security circuits are designed to prevent intrusion from the outside by opening and closing windows, doors, etc., and are often not used when people are present during the day. Generally, it is configured to be set and functioning when you are away from home or when you go to bed at night. For this reason, the security circuit must be able to be set and reset at any time. In this embodiment, it is configured to be set by pressing the security button 204 provided on the base unit 2, and reset by pressing it again.

Now, to give an overview of the operation of the security circuit, as mentioned above, when the lock-type security button 204 provided on the base unit 2 is pressed, the control unit 243 in the receiving circuit 24 is activated and a signal is sent to the alarm circuit 25 ( (root) to send out (earth energy). In the alarm circuit 25, based on the signal, the crime prevention receiving section PC ₆ of the receiving section 241,
Sends a set signal to PC ₇ to set PC ₆ and PC ₇ (root). On the other hand, based on that signal
Since a lamp display signal is sent to the display unit 207 of the base unit 2 through the route b', the security lamp lights up completely, clearly indicating that the security monitoring system is in place.

If the security sensor 501 operates in this state,
Abnormal signals (ground air) are input from the sensors to the crime prevention receiving units PC ₆ and PC ₇ . When the crime prevention receiving sections PC ₆ and PC ₇ send corresponding signals to the signal sending section 242, the signal sending section 242 operates the control section 243 and activates the alarm circuit 25 with its output (route). When the alarm circuit 25 is activated, a signal is sent to the door phone adapter 23 to activate the door phone adapter 23 and operate the main amplifier 22.

Also, terminal DA ₁ of door phone adapter 23 is terminal K ₁
~ _K5 is also connected, and the signal (power supply) transmitted there is sent to the all-button telephone, that is, the base unit 2 or handset 3, via the diode SD, and activates the telephone amplifier 210 or 310.

On the other hand, in the alarm circuit 25, an alarm signal (for example, 1 KHZ) is generated by the signal from the control unit 243, so the alarm signal is transmitted through the speaker calling loop (alarm circuit 25 - door phone adapter 23 - main amplifier 22
-Transformer T-telephone amplifiers 210 and 310-
All base units 2 and slave units 3 via speaker SP)
The device is configured so that it can be emitted all at once to notify the user of an abnormal situation through an audible display.

Furthermore, since an alarm priority switching contact _t1 is provided in the alarm circuit 25, when the alarm circuit 25 is activated, the _t1 contact provided between the tone switch 20 and the door phone adapter 23 is opened, and the station Even while the line ringing tone and extension ringing tone are being sent out, these signals are cut off and only the alarm signal is sent out with priority.

Also, since the other end DA ₂ of the door phone adapter 23 is also connected to the P ₃ terminal of the base unit 2 and handset 3 via the P ₃ terminal of the extension circuit 19, a signal from the alarm circuit 25 causes a signal to be sent to the door phone adapter 23. The provided oscillator operates and sends out an intermittent signal with a fast cycle (approximately 2HZ). Therefore, the extension lamps PL of the base unit 2 and slave unit 3 flash to visually indicate that there is an abnormality.

On the other hand, from the signal sending unit 242 to the display unit 2 of the base unit 2
Since a lamp display signal is sent to route 07, the sensor type is displayed.
In other words, the display panel of the display section 207 is marked with a picture to indicate that the lamps are for crime prevention (electric locks, windows, doors), disaster prevention (gas, smoke, heat), and bath (water level, temperature). The lighting location differs depending on the type and is configured to be distinguishable.

According to this route, when a signal indicating an abnormality is inputted from the security reception units PC ₆ and PC ₇ , the security mark lamp lights up, so that it can be seen at a glance that there is an abnormality in the security sensor 501.

Furthermore, when a signal is input from the security sensor 101 to the security receiving units PC ₆ and PC ₇ , the signal sending unit 242
from the second output end, which is different from the output end to the base unit 2.
A lamp display signal is sent out via a route to the display section 206. Since the name, number, etc. of the room in which the security sensor 101 is arranged is written on the display panel of the display unit 206, it is possible to know by location which room the abnormality has occurred in by the lamp display.

In this way, if there is an abnormality in the security circuit, an alarm signal will be emitted from the speakers of both the base unit 2 and slave units 3, and at the same time, the extension lamps PL of both the base unit 2 and slave units 3 will change to a faster cycle. The type display section 207 of the base unit 2 lights up, which clearly indicates what kind of abnormality is occurring, and the location display section 2 also lights up.
06 lights up, so you can instantly know in which location (room) there is an abnormality.

In addition, if you want to reset the security button 204 during the day when there are residents, please press the locked security button 2.
If you press 04 again, it can be restored mechanically.

Next, we will provide an overview of the operation of the disaster prevention circuit.

The disaster prevention circuit is designed to prepare for gas leaks and fires (smoke and heat), so these sensors are always set and configured to function at any time.

In this embodiment, the smoke sensor 102 is a smoke receiving section.
PC ₃ and the gas sensor 103 are connected to the gas receiving section PC ₄ , and the heat sensor 104 is connected to the heat receiving section PC ₅ , respectively, and their output ends are all connected to the signal sending section 242 .

Therefore, the signals from these disaster prevention sensors are sent to the signal sending section via the corresponding receiving sections _PC3 to _PC5 , and are sent to the parent via the alarm circuit 25 in the same manner as the operation of the crime prevention circuit described above. An alarm signal (an audible display signal emitted from Spica SP and a visible display signal that causes the extension lamp PL to flash) is sent to the machine 2 and each slave machine 3.

On the other hand, when the smoke or gas sensor is activated, the signal sending unit 242 sends a lamp display signal to the display unit 207 of the base unit 2 through the route shown in FIG. A lamp lights up to notify you of an abnormality.

In addition, when the heat sensor is activated, a lamp display signal is sent through the route , which lights up the lamp in the heat display window, thereby informing the user that there is a fire.

Next, the operation after the crime prevention circuit or disaster prevention circuit has finished operating will be described.

If the cause of these circuits has been activated and the alarm display (alarm sound, alarm lamp) is to be stopped after the abnormal situation has been dealt with,
It can be stopped by operating the base unit 2 and slave unit 3.

First, in the base unit 2, when the non-locking alarm cut-off button 205 is pressed, a signal (ground air) is input to the control unit 243 of the receiving circuit 24 via the route. Since the signal output to 25 is stopped, the operation of the alarm circuit 25 is cut off and the alarm signal (1KHZ) is output.
Since the sending of the lamp signal stops as well as the sending of the lamp signal, the blinking of the extension lamp PL also stops. In addition, in the handset 3, the non-locking extension call button 303 is pressed.
If you press the BK ₆ switch, you can stop it in the same way as the alarm disconnection route for base unit 2.

Next, we will discuss the water temperature and water level monitoring circuit.

The water temperature and water level monitoring circuit mainly detects the temperature of bath water and the water level of bath water accumulated in the bath gutter and issues a warning, and the water temperature sensor or water level sensor is connected to the common receiver PC ₁ .
This output end is connected to the FP terminal of the extension call route via the route of.

Therefore, when the water temperature or water level sensor is activated, a signal (power supply) is transmitted to the FP terminal via the common receiver PC ₁ , so that the telephone amplifier 21 of the base unit 2
Start 0. Also, that signal is the tone switch 20
, the extension calling signal (for example, 500 HZ) from the sound source circuit 21 is supplied to the speaker SP of the base unit 2 via the door phone adapter 23 and the main amplifier 22, so that it is emitted only from the base unit 2.

On the other hand, from the common receiving unit PC ₁ to the display unit 20 of the base unit 2
Since a lamp display signal is sent through route 7, a lamp is lit in the display window of the bath to alert the occupants.

In other words, if you set the detection level of the water temperature or water level in the bath, etc. appropriately, you will know that the appropriate temperature or amount has been reached when the main unit 2 displays a lamp and sounds a 500Hz sound, so you can go to the bathroom and use it. All you have to do is close the main valve or the water faucet, and the effect is to give residents peace of mind.

Furthermore, the operation circuit of the emergency bell 8 will be described.

The emergency bell is connected to the output end of the common receiver PC ₁ and can be sounded by the following two means. One is the emergency alarm button 2 provided on the base unit 2.
By pressing 03, a signal is input to the bell signal receiving section PC ₂ through the route, and the corresponding output is transmitted to the common receiving section PC ₁ , which activates the relay and activates the emergency bell 8 by its contact. be.

Another method is to input the signal from the emergency button 7 connected to the bell signal receiving section PC ₂ , transmit it to the common receiving section PC ₁ in the same manner as described above, and raise the emergency bell 8.
can be started.

To stop the emergency bell 8 from ringing, the emergency alarm stop button 202 provided on the base unit 2 is pressed to restore and stop the relay of the common receiver PC ₁ .

Next, the electric lock operation circuit will be described.

Electric locks are installed on doors such as gates, entrances, and back doors so that mechanical locking and unlocking can also be performed by electrical control. Therefore, it will be more effective if used in combination with a conventionally used mechanical lock.

Only electric locks will be explained here.

First, these doors are equipped with a sensor that detects the open/closed state of the door, and when the door is open, the information (Jiki) is sent to the common receiver PC _{1 .} The corresponding output is sent to the display section 207 of the base unit 2 through a route, and the above-mentioned security mark lamp is turned on.

In other words, on the display sections 206 and 207 of the parent device,
When the door is opened, only the security mark lamp on the display section 207 lights up, the location display lamp on the display section 208 lights up, and the location display lamp on the display section 206 does not light up, but the windows of each room are opened. Since the location display lamp on the display section 206 lights up and the crime prevention mark lamp on the display section 207 also lights up, it is clear to distinguish between opened doors and windows.

These doors are provided with an electric lock 6 including a latch 61, an electric lock main body 62, and an electric lock release switch 624 in addition to a sensor for detecting the opening and closing of the door.

As this electric lock 6, for example, a commercially available product name "Bull Lock" (manufactured by Aiphone Co., Ltd.) or the like is used. FIG. 8 is an explanatory diagram of the functional operating principle of the electric lock 6, in which a latch 61 is attached to the door and an electric lock 62 is provided on the wall. First, a latch movable part 611 is attached to the tip of the latch 61.
is provided, and is configured to be able to move freely in the direction of arrow A-A', but to stop at a position approximately perpendicular to the axial direction of the latch 61 and not to rotate in any direction beyond that.

On the other hand, the electric lock main body 62 is provided with a rotary plate 622 movable in the direction BB' about a rotating shaft 621, and an AC electromagnet 623 is provided on one side of the rotary plate 622. Therefore, the rotating plate 622 is an AC electromagnet 623
It will rotate until it comes into contact with the . The AC electromagnet 623 is constantly supplied with AC voltage from the power supply circuit 25 of the main device 1 via the electric lock/unlock switch 624.
AC10V is applied, and due to this magnetic attraction, the rotary plate 622 does not rotate in the B' direction while the current is being applied. Further, the electric lock/unlock switch 624 may be a locking type or a non-locking type, and is essentially an AC electromagnet 62.
The rotating plate 622 temporarily interrupts the AC input to 3.
It is sufficient if it can be made to freely rotate in the B′ direction as well.

In other words, as the door is closed, the latch movable part 61
1 comes into contact with the rotating plate 622 and rotates in the A′ direction,
When the door closes, it will come to rest in the position shown. If the AC electromagnet 623 is not energized, the rotating plate 622
Since it rotates freely in the B' direction, the door can be opened and closed as appropriate. When the power is on, the rotary plate 622 is magnetically attracted and fixed at the position shown, and the door will not open even if an attempt is made to open it. If it is desired to open the lock, the input to the AC electromagnet 623 can be cut off using the electric lock release switch 624 or the like as described above.

In this embodiment, the input to the AC electromagnet 624 can be cut off by using the electric lock release button 201 provided on the base unit 2 in addition to the electric lock release switch 624.

That is, when the non-lock type electric lock release button 201 of the base unit 2 is pressed, a signal (ground air) is sent to the common receiver PC ₁ through the route while the button is being pressed, and a signal (ground air) is sent to the common receiver PC ₁ . The relay is actuated to open its contacts, cutting off the AC voltage 10 and controlling the alternating current magnet 622 to unlock the door. The door can also be unlocked by pressing the electric lock release switch 624 provided on the inside of the door via the same route p'.

On the other hand, since a signal (ground air) is inputted to the control unit 243 from the common receiving unit PC ₁ through the route, this signal causes the operation of the alarm circuit 25 to be cut off in the same way as the above-mentioned alarm cutoff route. No signal is sent.

In other words, in order to unlock the electric lock 6 that is being monitored when you return from outside, you must press the electric lock release button 201 on the base unit 2 of the resident indoors or the electric lock release switch 6.
24, but there is no need for the alarm to be sent out in this case.

Also, when the door is opened, the display section 20 of the base unit 2
The security mark lamp 7 will light up, so if you hold down the electric lock release button 201 while it is lit and release it when the lamp goes out, the system will confirm that the person returning home has entered the house and then resume monitoring mode. This is extremely convenient because it can be easily done using the base unit 2 even if you are not at the door.

When opening and closing the door when a visitor arrives, the main unit 2 may be used to monitor and control the door in the same manner.

Furthermore, based on the abnormal signal from the opening of the electric lock or door input to the common receiver PC ₁ and the abnormal signal from the crime prevention sensor or disaster prevention sensor input to the signal transmission unit PC ₈ , the signal is sent to the attached fire station, police station, etc. A remote communication device for communication, a control room communication device for contacting a manager in an apartment building such as a condominium, and an inter-group communication device for informing neighbors in the event of an abnormality. It also has a function that allows you to automatically dial and make a call to a corresponding predetermined location using a telephone line etc. via a telephone line (detailed explanation is omitted). You can make an emergency call as soon as possible.

In addition, in the explanation so far, base unit 2 is one unit, and slave unit 3 is
Although we have described the configuration shown in Figure 2a, in which the required number of units are connected for monitoring, the configuration is not limited to this, and when monitoring in each room, the base unit 2 can be used in conjunction with the configuration. It is clear that the configuration shown in FIG. 2b can be used. In this case, since the base unit 2 has branch connections for both incoming and outgoing lines, operations such as various displays are completely the same as the base unit 2 shown in FIG. 2a.

Furthermore, in the embodiment of FIG. 2c, FIGS. 2a and b
The difference is that the receiving circuit 24 is housed in the base unit 2, but in reality, the wiring between the various sensors 5 and the main unit 1 and between the main unit 1 and the base unit 2/slave unit 3 is different. Since the only difference is that the basic functions and operations are the same as those in FIGS. 2a and 2b, a detailed explanation will be omitted.

Furthermore, the various sensors connected to the receiving means are not limited to those described so far, and furthermore, not all of them are necessarily described.
In short, it is configured by selecting and adding them as appropriate according to the requirements.

Next, FIGS. 3 to 8 show specific embodiments of the present invention.
The explanation will be based on the circuit diagram shown in the figure.

FIG. 3 mainly shows the common receiving section PC ₁ of the receiving circuit 24, and shows the electric lock release button 20 of the base unit 2.
1 and electric lock release button 624 provided on the entrance door
The temporary unlocking of the electric lock 6 is controlled by the signal from the receiver PC 2, and the emergency bell 8 is operated by the emergency bell operating signal sent via the receiver PC ₂ , and the alarm circuit operating signal is sent to the signal transmitter 242. (PC ₈ ),
The signal is sent to each receiving circuit of the control unit 243 (PC ₉ ), and the emergency stop button 202 of the base unit 2 sends a signal to stop the emergency bell 8 and stop the alarm sound to the control unit 248 (PC ₉ ) to stop the alarm sound. Also bath sensor 505,5
This is a common receiving circuit that lights up the bath indicator light 207 of the base unit 2 with the signal from the base unit 2 and causes the base unit 2 to output an alarm sound. In Figure 4, PC ₂ is the main device 2
This receiving circuit is operated by signals from the emergency alarm button 203 and the emergency button 7, and sends a signal to the common receiving circuit _PC1 to ring the emergency bell 8. PC ₃ operates with a signal from the smoke sensor 508, PC ₄ operates with a signal from the gas sensor 502, PC ₅ operates with a signal from the heat sensor 504, and each sends a signal to the signal sending unit PC _8. The circuit configuration of the smoke, gas, and heat receiving circuits is the same as PC ₂ . In FIG. 5, PC ₆ and PC ₇ are operated by signals from crime prevention sensors 501 installed at various locations, display the operating location of the sensor on the display unit 206 of the base unit 2, and send a signal to the signal sending unit PC ₈ . PC ₆ and PC ₇ both have the same circuit configuration. In Figure 6, PC ₈ is PC _3,4,5,6,7
It is operated by the signals from each receiving circuit, and displays the type of abnormality such as smoke (gas), fire, and security (window) on the base unit, and sends an abnormality signal to the control unit PC ₉ , which is installed separately. It is a signal sending unit configured to send signals to the remote communication device 9 and the management room communication device 10. In FIG. 7, PC ₉ is connected to door phone 4 via door phone adapter 23,
It is also connected to the security button 204 and the security button 205 of the base unit 2, and controls the operation of the alarm circuit PC ₁₀ by the operation of the security button 204 and the security button 205, and also controls the operation of the alarm circuit PC _10.
PC 10 is a control unit that sends a signal to the alarm circuit of PC ₁₀ based on a signal input from the control unit PC 9. PC ₁₀ operates based on a signal input from control unit PC ₉ , and activates the door phone 4 as well as all button telephones and door phones. This is an alarm circuit that controls the ringtones of central office lines, extension lines, and doorbells, and sends out alarm sounds with priority.

Hereinafter, specific circuit operations will be explained for each functional operation with reference to FIGS. 3 to 8.

First, to explain the crime prevention circuit, it is provided in the main unit 2 in order to put the alarm circuit 25 into a standby state so as to immediately send out an alarm sound when the crime prevention sensor 501 installed in advance in the windows and entrance doors of each room is activated. When the security button 204 is pressed, the +R power supply of the control unit PC ₉ - PC ₉ /AL relay - is activated as shown in Fig. 7.
PC ₉ /4B terminal - Connector B ₁₂ - Main unit security button 204
− Grounding route (route) of control unit PC ₉
Since the AL relay operates and the PC ₉ /5A terminal becomes ground due to the AL contact, the flip-flop FF ₁ of the alarm circuit PC ₁₀ is set, and the set output further sets the flip-flop FF ₃ , which is connected to the transistor TR ₁ through the gate GT ₁ . turns on and the D relay operates. Therefore, by the operation of the contact d ₂ , -R power supply of the base unit 2 - base unit security indicator light 207 - connector B ₁₁
- PC ₁₀ /6B terminal - PC ₁₀ /d ₂ contact - The security indicator light 207 of base unit 2 lights up in the ground circuit, and in this state it is confirmed that the security monitoring function has been set.

At this time, if the security button 204 is pressed while the window, etc. in which the security sensor 501 is installed is open, the security window mark on the display section 207 lights up, informing you that the window, etc. in which the sensor in each room is installed is turned on. The system is designed to encourage people to re-check whether their doors are locked.

The security monitoring function has been set up and the security indicator light 20 is turned on.
For example, when the window of the room 2 is opened while the PC 7 is lit, the security sensor 501 operates to operate the relays PC ₆ and PC ₇ in the next circuit shown in FIG. Security receiving unit PC ₆ +R power supply -PC ₆・
O relay PC ₆ /4B terminal - TB ₄ terminal 1 - Security sensor 501 - TB ₄ terminal 12 - Earth The O relay of PC ₆ operates and its contact O ₁ operates to turn on +R of base unit 2. Power supply - Display of base unit 2. Light emitting diode for displaying "room 2" of light 206 - Connector B ₂ - TB ₈ terminal 2...TB ₆ terminal 6 - PC ₆ /4A terminal - PC ₆ /O ₁ contact - PC ₆ /20A
Terminal - PC ₁₀ /6A terminal - PC ₁₀ /d ₁ contact - PC ₁₀ The location indicator light "Room 2" on base unit 2 lights up when connected to ground.

Note that settings between the TB ₆ terminal and TB ₈ terminal may be made as appropriate.

Further, the G relay of the signal sending unit PC ₈ shown in FIGS. 5 and 6 operates in the following circuit. PC ₈ 's +R power supply - PC ₈ /G relay - PC ₈ /8B terminal - PC ₆ /19A...
PC ₆ /6B terminal - PC ₆ /O ₂ contacts - PC ₆ /20A -
PC ₁₀・6A terminal - PC ₁₀・d ₁ contact - operates with ground, and the operation of the ₃ contacts shown in Figure 6 causes main unit 2's +R power supply - main unit 2's indicator light 207 "window" display light emitting diode −Connector B ₁₇ −PC ₈・8A terminal −PC ₈・g ₃
The type indicator "window" of the base unit 2 lights up due to the contact-ground. At the same time, the g ₁ and g ₂ contacts of the signal sending unit PC ₈ communicate the crime prevention information to the control room communication device 9 and the remote communication device 10 via the TB ₁ terminals 4 and 5. Furthermore
_{The 4} contacts of PC ₉ operate the KA relay of control unit PC ₉ in the +R power supply of PC ₉ - PC ₉ /KA relay - PC 9/6B terminals - PC ₈ /10A terminals - PC ₈ /g ₄ contacts - ground circuit. As shown in FIG. 7, after the KA relay is activated, an alarm sound is sent out from the base unit 2, handset 3, and door phone 4, and an alarm is displayed, as in the case of disaster prevention, as will be described later.
To stop the alarm sound, press the alarm button 205 on the base unit 2 or the extension call button 30 on the slave unit 3, as in the case of disaster prevention described later.
Stop by pressing 3 BK ₆ . To cancel the security monitoring function, press the security button 204 on the base unit 2 again to turn off the switch, so the AL relay in the control unit PC ₉ will be restored, and then the alarm circuit will be activated.
The A relay of PC ₁₀ is also restored and IC ₅ is reset and released. After that, even if the security sensor 501 operates, neither the alarm sound nor the display on the base unit is output.

Note that the display on the base unit 2 for the security sensor installed at the entrance door is configured to be displayed at all times regardless of the security button 204.

Here we will discuss the normal operation of the door phone DP.

The CB relay of the door phone adapter DAD is the main device 1
Since the power supply circuit 27 operates at the same time as its output voltage, the operating voltage is always applied to the door phone DP by the closing of the contact cb.

Therefore, in the normal operation of the doorbell, when a visitor presses the non-locking pushbutton DK of the doorbell DP from the outside, the transistor _TR3 of the doorphone adapter DAD turns on, and its output sets the flip-flop _FF6 , which The set output activates the chime sound generation circuit CM, generates a "ping-pong" sound, and sends it to the main unit amplifier 22 via the GT ₈ - GT ₃ - GT ₄ - DAD/8 terminals to the base unit 2 and slave unit. It is configured so that it is transmitted from three speakers SP. In addition, to start the speaker SP of the base unit 2 and slave unit 3, the transistor TR ₄ is activated by the output of the flip-flop FF ₆ of the door phone adapter DAD, and the output is sent to the terminal D ₀ of the main unit 1 via the DAD/5 terminal. For example, if the D ₀ terminal and K ₁ are connected by a jamb wire JL, voltage is applied only to the speaker SP of the base unit 2 in the case of FIG. 2a, and the speaker SP is activated. If the D ₀ terminal and K ₁ to _{K 6} are all connected, all speakers SP are activated.

When either the base unit 2 or the handset 3 raises the handset, the extension circuit 19 is activated to form an extension call loop and supply a call current between the call lines P ₁ and P ₂ of the extension control line 12. The audio from the handset is sent to the hybrid circuit HYB of the door phone adapter DAD, and the amplifier DAD-SAMP-Transformer T-Contact cb-
Door phone DP hybrid transformer HYB-T-
It is sent out via the speaker SP route and contacted to the visitor. Audio from the visitor is recorded using the microphone MIC-AMP-
The signal is transmitted to the handset of the handset via communication lines P ₁ and P ₂ along the route HYB-T-contact-T-DAD-MAMP-HYB, and mutual communication with the doorbell is performed.

Next, to explain the disaster prevention circuit, among the gas sensor 502, smoke sensor 503, and heat sensor 504 installed in various places in Fig. 4, for example, 5
When the smoke sensor of 03 detects an abnormality, Fig. 4 PC ₃
In PC ₃・+R power supply −PC ₃・J ₂ relay−
PC ₃ /4B terminal - TB ₂ terminal 9 - Smoke sensor - 503
-TB ₂ terminal 14- The J ₂ relay operates on the ground route, the jz ₂ contact closes, and the PC _8. +R power supply -
PC ₈ /E relay - PC ₈ /4B terminal - PC ₃ /9A terminal -
The PC ₈ E relay operates through the PC ₃ /jZ ₂ contact-ground route. Therefore, as shown in Figure 6, by closing the _e4 contact of the E relay of PC _{8 ,} PC _9. +R power supply - _{PC 9.KA} relay - PC _9.6B terminal - PC ₈ . PC ₉ 's KA relay operates on _{the 4-} contact-ground route.

Therefore, as shown in Fig. 7, the flip-flop _FF3 of PC ₁₀ is set by the operation of the _KA1 contact of the KA relay, and the D-type flip-flop _FF4 is set, so that the potential of ALS becomes high. becomes low. As the potential of ALS becomes high, the 1KHZ alarm signal generated from the alarm signal oscillator OSC-1 reaches the GT ₂ - GT ₃ - GT ₄ - DAD・8 terminal of the door phone adapter DAD, as shown in Figure 2. Through the main device AMP ₂₂ as
The speaker 21 of the master unit 2 and slave unit 3 is sent to the RT line.
0.310 is output as an alarm sound.

On the other hand, since the potential of GT ₆ is low,
FF ₅ is set through GT ₇ and a one-shot pulse is output, so transistor TR ₂ is connected through GT ₇ .
Since the ALM relay is turned on for one time, the ALM relay operates for one time and then recovers.

Therefore, since the alm ₁ contact is closed once, the door phone DP operates in the following circuit. i.e. doorbell
The transistor
TR ₃ operates, flip-flop FF ₆ is set, and chime sound generating circuit CM is activated. However, under normal conditions, the potential of ALS is high, but KA
When the relay operates, it becomes a low potential due to the operation of flip-flop _FF4 , so it is an AND gate.
GT ₈ 's gate does not open and no chime sound is emitted.

On the other hand, when the KA relay operates, the flip-flop
Since the ALS potential of FF ₄ is high, the transistor
TR ₃ turns on and the T relay operates. Therefore, since the contact _t2 closes, the DA relay of the door phone adapter DAD operates, and since the contact _da1 closes, the alarm signal (1KHZ) from the alarm signal oscillator OSC-1 is sent to the hybrid circuit HYB-DAD-SAMP-T. −cb
An alarm sound is also sent out from the speaker SP of the door phone via the contact-door phone DP route.

At the same time, the alarm display signal oscillator OSC-2 is activated by the operation of the da ₂ contact, and the alarm display signal (2HZ) is activated.
The extension lamps PL of the base unit 2 and slave unit 3 are flashed all at once to send the signal to the _P3 terminal of the extension circuit 19 via the DA ₂ terminal, so that an abnormality can be audibly and visually indicated in any room. You can know.

Furthermore, if a flash light or the like is connected to the door phone 4, an alarm can be raised visually from the outside. Furthermore, as shown in Fig. 6, the signal sending unit PC ₈
An abnormal signal is sent to the separately installed control room communication device and remote communication device using the _e1 and _e2 contacts.

In addition, the e ₃ contact in Figure 6 connects the +R power supply of the base unit 2 - the light emitting diode for displaying "smoke" of the indicator light 207 of the base unit 2 - the connector B ₁₆ - PC ₈ /4A terminal - PC ₈ /e ₃
The type indicator light “smoke” on base unit 2 lights up at the contact point - ground. At the same time, as shown in Figure 4, J ₂
Since the relay operates, the jz ₁ contact of PC ₃ connects the main unit 2's +R power supply shown in Figure 5 - the light emitting diode for indicating "room 1" of the indicator light 206 of the main unit 2 - the connector B ₁ -
TB ₈ terminal 1...TB ₅ terminal 6 (Fig. 4) - PC ₃ /4A terminal - PC ₃ /jz ₁ contact - Ground circuit lights up "Room 1" of the location indicator light 206 of the base unit 2. In this way, the type and location of the anomaly can be displayed. When the cause is determined and the alarm sound is to be stopped, press the alarm button 205 on the base unit 2 as shown in Figure 7 to turn on the PC ₉ 's +R power supply - PC ₉ , AR relay - PC ₉ ,
8B terminal - Connector B ₁₃ - Main machine alarm button 205 - The AR relay is activated by the ground, and flip-flop FF ₃ of PC ₁₀ is set by the AR contact, and its output is GT ₉ ,
Reset flip-flop FF ₄ via GT ₁₀ . Since the ALS signal becomes low and the signal becomes high, the alarm circuit PC ₁₀ returns to the normal state and the main unit 2,
The alarm sound that was being sent from the handset 3 and the doorbell 4 stops. Also, when you want to stop the alarm sound on the handset 3, by pressing BK ₆ of the extension call button 303 on the handset 3, the alarm sound will be stopped by the same action as when you press the warning button 205 on the base unit 2. can do. If the status of smoke sensor 508 becomes normal, PC ₃ in Figure 4
The J ₂ relay has also been restored, and the signal sending section PC ₈ in Figure 6 has also been restored.
Since the E relay is also restored, the smoke in the main unit 2 and the indicator lights 206 and 207 in the room 1 go out. gas sensor 5
02. Even when the heat sensor 504 detects an abnormality, an alarm sound is sent out and the respective alarm indicator lights are lit in the same way as when the smoke sensor 503 is activated.

In addition, if the alarm circuit is activated when an incoming call is being sent from each button telephone or a ring tone is being sent from the doorbell in the state of receiving a call from a local office line, the alarm circuit PC ₁₀ will be activated if there is an incoming call.
The T relay (alarm priority relay) is configured to open the _T1 contact and cut off the incoming station line signal from the tone switch 20, and when there is an incoming call from the door phone 4, the alarm circuit is activated.
Flip-flop FF ₄ of PC ₁₀ causes the ALS signal to go high and the signal to go low, so GT ₈ generates the chime sound generation circuit CM caused by the operation of door phone 4.
It is configured so that only the alarm sound is sent out with priority, by controlling so that the signal from the alarm is not passed through.

Regarding the bath monitoring function (water temperature and water level monitoring circuit), as shown in FIG. 3, when the water temperature sensor 505 or water level sensor 506 installed in the bath operates (the case of water level sensor operation will be explained below)
PC ₁ 's +R power supply - PC ₁・C ₁ relay - TB ₂ terminal 1
-Water level sensor 506-TB ₂ terminal 8-ground
The _C1 relay operates and the "bath" display light emitting diode of the indicator light 207 of the base unit 2 lights up by the _C1 contact. Furthermore, the + _R power supply of PC ₁ is connected to the C ² ₁ contact.
C ₁ ² contacts - PC ₁ /14B terminal - TB ₇ terminal 1 - Main device terminal FP (Fig. 2) - Base unit 2 Start telephone amplifier 210 of base unit 2 with SP210.

At the same time, the tone switch 20 is activated by the signal (chiki), and an alarm signal (also used as an extension calling signal) is supplied from the sound source circuit 21 to the speaker SP of the base unit 2 via the door phone adapter 23 and the main device amplifier 22. Therefore, the base unit 2 sends out an alarm sound.
When the countermeasures (in this case, closing the water faucet) are completed and the water level sensor is restored, the alarm sound sent from the base unit 2 will stop and the bath indicator light will also go out.

Also, by setting the water temperature sensor to an appropriate temperature and boiling the bath, when the water temperature reaches the set temperature, the water temperature sensor will operate, and the main unit 2 will issue an alarm sound in the same way as when the water level sensor operates. The design is designed to alert you to this with a bath indicator light.

Next, the emergency alarm function will be explained. As shown in FIG. 4, the emergency bell 8 is activated by pressing the emergency alarm button 203 of the base unit 2 or the emergency button 7 installed outside. The operation is that when the emergency alarm button 203 of the base unit 2 is pressed, the _M1 relay of the receiver PC ₂ switches the PC ₂ 's +R power supply - PC ₂ , M ₁ relay - PC ₂ , 7B.
It operates in the terminal-connector B ₂₁ - emergency alarm button 203 - ground circuit, the B relay of PC ₁ operates with the Ml ₂ contact, and the BA relay operates by switching the contact b. The BB relay operates with the ba contact, the bb ₁ contact rings the emergency bell 8, and the bb ₂ and bb ₃ contacts ring the 6th emergency bell.
As shown in the figure, an emergency alarm signal is sent to the control room communication device and remote communication device via the TB ₁ terminal, and the KA relay of the control unit PC ₉ is activated by the bb ₄ contact.
After the KA relay operates, it is the same as during disaster prevention. still,
The BB relay is activated even if the emergency alarm button 203 is released.

On the other hand, as shown in FIG. 3, the emergency bell 8 can be stopped ringing by pressing the emergency alarm stop button 202 on the base unit 2.
PC ₁ 's +R power supply - PC ₁ /BR relay - PC ₁ /11B
Terminal - Connector B ₂₀ - Emergency alarm stop button 202 - The ground circuit operates the BR relay of common receiver PC ₁ , and the operation of the br contact disconnects the self-holding circuit of the BB relay by the bb ₄ contact, thereby turning off the BB relay. The emergency bell 8 is restored, the operation of the emergency bell 8 is stopped, and the normal state is restored.

Regarding the electric lock release function, by setting an operating knob (not shown) provided on the electric lock body, the electric lock becomes energized and the door is locked. When a family member returns home, the base unit 2 answers via the doorbell 4 and the door is opened using an electric lock release button 20 provided on the base unit 2 as shown in FIG.
When 1 is pressed, PC ₁ 's +R power supply - PC ₁ /A relay -

As described above, since the present invention is a button telephone device having an emergency alarm centralized monitoring function, the telephone device for communicating with the conventional office line and extension line and the system dedicated to the emergency alarm monitoring function are separated into separate devices. Not only does it have the advantage of consolidating all the functions previously used, but it also allows for emergency contact to a specific location using a telephone line.

In particular, in the past, alarm information could not be sent when the line was not available, but with the present invention, if the line is in monitoring mode, it is possible to display the alarm with priority even if the line is in use, making it possible to constantly monitor the status. has advantages.

In addition, in all button telephones, the speaker and extension lamp for transmitting the office line ring tone and extension ring tone can be shared by the function of the button telephone device and the alarm monitoring function, so the alarm tone can be transmitted with a simple configuration.
