Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a home security system for informing of occurrence of a fire or gas leak, and is particularly suitable for application to a two-family home.

[0002]

2. Description of the Related Art Fire alarms and gas leak alarms for informing residents and nearby residents of the occurrence of fires and gas leaks have become popular as security devices for home use.
In addition, as a security device for two-family homes where a parent and a couple live independently, when there is a sudden change in the elderly who is using the toilet or taking a bath, the situation can be used to describe the situation with the family living together or in the neighborhood. There are also so-called bath calls and toilet calls that notify people. In recent years, such security devices are often installed side by side with switching systems for making external and internal calls. Switching systems for two-family homes switch between two external lines (telephone lines) with the main device. It is designed to control. By this switching control, external telephone calls and internal telephone calls are made by a plurality of telephone cordless handsets installed separately for the residence of the parent couple and the child couple. The exchange system also includes a television (T
V) type doorphone or doorphone for voice only can be connected. In the security device attached to such an exchange system, when the fire sensor or gas sensor detects a fire or gas leak, or when the emergency button is pressed (turned on), the security bell and the security slave unit simultaneously send the security sound. Is issued. In this case, the alarm is stopped by pressing the emergency button again. Further, in a security device including a bus call, a toilet call, etc., all the security units operate when a security sound is issued, so that power consumption is large. Therefore, the number of terminals is determined in consideration of the maximum supply current, which is the rating of the main controller, and the length (resistance value) of the transmission line.

As proposals for improving this type of security device, Japanese Unexamined Patent Publication No. 1-168195 discloses an extension slave unit for a telephone exchange system and Japanese Unexamined Patent Publication No. 62-1.
The "home telephone system" disclosed in Japanese Patent No. 72852 can be mentioned. In the example of Japanese Patent Laid-Open No. 1-168195, an extension slave unit for connecting a telephone (slave unit),
It has a built-in amplification buffer for compensating the attenuation of transmitted security signals and a power supply that supplies power only to the connected extension slave units. As a result, a larger number of slave units can be connected without being limited by the electric capacity of the main unit that can be connected to the slave units. In addition, JP-A-6
In the example of Japanese Laid-Open Patent Publication No. 172852, a large number of security units are divided into a plurality of groups, and the security units of the divided plurality of groups are controlled so as to intermittently issue a security sound, thereby consuming per unit time. The current is reduced and more security units can be connected.

[0004]

By the way, in the example of Japanese Unexamined Patent Publication No. 1-168195 in the above-mentioned conventional example, although a larger number of telephones can be connected, this stoppage occurs when an alarm is issued in an emergency. Is performed by pressing the emergency button again or pressing the emergency stop dedicated button. in this case,
Residents may move around to identify the location of an emergency, which may result in continued alarms for a long time. Therefore, power consumption is increased, and in the case of a false alarm, annoyance to nearby residents is likely to occur. Also, JP-A-62-1728
In the example of Japanese Patent Publication No. 52, since the security units divided into a plurality of groups intermittently generate a security sound, the current consumption per unit time is reduced, but when one of a plurality of emergency buttons is pressed. The same security sound is issued from all security units. In this case, the location of the emergency situation in which the emergency button is pressed is unknown, and the resident cannot quickly reach the location where the emergency button is pressed. In particular, in a two-family house with many residents, every resident is confused about the location of the alert every time it is reported.

The present invention solves the problems in the prior art. It eliminates unnecessary power consumption in issuing a security sound in a two-family house in which a plurality of security slaves are arranged, and eliminates false alarms. It is an object of the present invention to provide an in-house security system that can prevent unnecessary sounding of security sound for a long time.

[0006]

In order to achieve the above-mentioned object, a home security system according to claim 1 comprises a sensing sensor for sensing an occurrence of an emergency in the house and outputting a sensing signal, and the sensing sensor. An emergency occurrence notification means for notifying the occurrence of an emergency based on the sensing signal of
When a time is measured from the start of notification by the emergency occurrence notification means, and when the time measuring means measures a preset predetermined time, the emergency occurrence notification means is notified of the occurrence of the emergency. And a notification stop control means for performing control for stopping.

According to a second aspect of the present invention, in addition to the configuration of the first aspect, the home security system further comprises a display means for emitting light and / or a screen to indicate the occurrence of an emergency, and the clock means for a predetermined time. A display start control means for controlling the display means to display the occurrence of an emergency when the time is measured, and a display canceling means for canceling the display after the occurrence of the emergency on the display means Is.

Further, in the home security system according to the third aspect of the present invention which achieves another object, a plurality of notification switches that a person turns on in an emergency and different alarm sound information corresponding to each of the plurality of notification switches are provided. The alarm sound information storage means for storing, the identification means for identifying the notification switch that has been turned on among the plurality of notification switches, and the alarm sound information corresponding to the notification switch for which the on operation has been identified by the identification means. The alarm sound information reading means for reading from the information storing means and the emergency occurrence notification means for notifying the occurrence of the emergency based on the alarm sound information from the alarm sound information reading means are provided.

[0009]

In the home security system according to the first aspect of the present invention having the above-mentioned structure, the time from the start of reporting the occurrence of an emergency is measured based on the detection signal from the detection sensor. Then, when the predetermined time set in advance is counted, the notification of the occurrence of the emergency is stopped. Therefore, all security slaves will not continue to be issued unnecessarily. For this reason, useless power consumption does not occur in issuing a security sound in a two-family house in which a plurality of security slaves are arranged. In addition, it is possible to prevent the security sound from being issued for an unnecessarily long time in the event of a false alarm.

According to another aspect of the present invention, in the home security system, after the notification of the occurrence of the emergency is stopped for a predetermined time, the occurrence of the emergency is displayed by, for example, blinking of the light emitting element, screen display, or both. In addition, the display is manually canceled. Therefore, after the stoppage of issuing the security sound, the issuance of the alert is quickly and surely known.

According to another aspect of the home security system of the present invention, different alarm sound information is stored corresponding to each of the plurality of notification switches. Then, the ON state of the plurality of notification switches is identified, alarm sound information corresponding to the ON-operated notification switch is output, and the occurrence of an emergency is notified based on the alarm sound information. Therefore, the alarm location where the emergency button is pressed in a two-family house where a plurality of emergency buttons are installed can be easily identified by sound quality and the like.

The external telephone function, the extension function, and the TV will be described below.
The operations of the doorphone function and the security function will be described in order. First, the operation of the outside line telephone function will be described. Either one of the outside lines 1 or 2 from the public switched telephone network,
Alternatively, the MPU 64 identifies both calls (incoming calls) through the central line circuits 41 and 42. MPU64 based on this identification
Controls the extension circuits 45 and 46, the communication path switch 48, and the signal supply connection section 49. With this control, the ring tone signal from the outside line ring tone signal generation unit 51 is transmitted through the module connector units 30a to 32b of the tenants A and B to the facsimile machines 21a and 21b and the security telephone slave units 22a to 22b.
3b.

By this call, the ringer of the security telephone slave units 22a to 23b and the speakers in the module connector units 30a to 32b ring. Based on this call, one security telephone slave unit (22a-2
In 3b), when the external lines 1 and 2 (not shown) are switched and an off-hook for picking up the receiver is performed, the MPU 64 identifies this off-hook signal through the extension circuits 45 and 46. Based on this identification, the MPU 64 determines that the central line circuit 41,
42, the call path switch 48 is controlled. By this control, the line connection (call path closing) with the telephone switching network (central office switch) is performed by detecting the response of one of the outside lines 1 and 2 that has received a call. After that, the call path restoration process in the public switched telephone network is performed based on the call with the destination telephone and the end signal by the on-hook at the end of the call.
Even when a facsimile message is received by the facsimile machines 21a and 21b, the security telephone slave units 22a to 22a.
It operates similarly to 23b. If the automatic facsimile message reception switching function is provided, the facsimile machines 21a and 21b are automatically switched by the training signal to receive the facsimile message.

In the operation of the extension function, the incoming call response of one of the outside lines 1 and 2 is put on hold, and an extension call is made between the tenants A and B. Alternatively, an extension call is made between tenants A and B. In this case, if any of the security telephone handsets 22a to 23b calls an extension by pressing an extension button divided by an extension number (not shown),
This call is sent to the MPU 64 through the extension circuits 45 and 46.
Identifies. The MPU 64 sends an extension ringing tone from an extension ringing tone generation circuit (not shown) to the security telephone subunits 22a to 23b to be called. After that, a call is made on the extension security telephone subunits 22a to 23b, and the MPU 64 processes the end of the call based on the on-hook signal at the end of the call and is ready to accept incoming calls from the outside lines 1 and 2. Return control processing is performed.

In the operation of the TV intercom function, the TV intercom 11a and the intercom 12a in the tenant A are used.
And the TV intercom monitor 20a work together. In addition, the TV door phone 11b and the door phone 12 in the tenant B
b and the TV intercom monitor 20b work together. That is, TV intercoms and intercoms are often used independently in the living parts of a parent couple and a child couple in a two-family house. When a visitor or the like presses the chime button of the TV intercom 11a, the MPU 64 captures this chime signal through the intercom control unit 60, and
Controls the operation of the V-door phone system. Further, the intercom control unit 60 controls the signal supply connection unit 49, and under this control, the intercom ringtone signal from the intercom ringtone signal generation unit 53 is transmitted through the extension circuits 45 and 46 to the module connector unit 30.
It is sent to the speakers a to 32b, and the speaker sounds and emits a chime sound. Further, the intercom control unit 60 is T
The power supply (startup) to the V doorphone 11a is controlled.

At the same time, the TV doorphone I / F circuit 9 processes a chime sound signal from the intercom control unit 60, a voice signal from a microphone (not shown), and an image pickup signal from an image pickup unit (not shown) (for example, CCD camera, image pickup tube). Then T
It is sent to the V doorphone monitor 20a. After this, TV
An image display unit (for example, LCD,
While the resident in the room looks at the visitors displayed on the CRT), they talk using the handset (handset).
It should be noted that only the voice conversation is performed between the doorphone 12a and the TV doorphone monitor 20a, and the operation is the same as that of the TV doorphone 11a. The operation between the TV intercom 11b and the intercom 12b in the tenant B and the TV intercom monitor 20b is also similar to the operation in the tenant A.

Next, the operation of the security function will be described. FIG. 4 is a timing chart showing the processing signals of the security operation and the processing timing thereof in the configuration of the first embodiment, and FIG. 5 shows the processing procedure of the security operation in the configuration of the first embodiment. It is a flowchart. This security operation is the same for both tenants A and B. Here, only tenant A will be described. 1 to 5, the fire sensor 1
When 5a senses a fire or the gas sensor 16a senses a gas leak, a time T at which the security sound is automatically stopped after the security sound is issued by pressing the emergency button 17a with a human finger. Is preset (step S10 in FIG. 5).

In this setting process, the keyboard 28d of the security telephone slave units 22a and 23a shown in FIG. 3 is operated,
This is performed based on the program stored in the ROM (not shown) in the MPU 64. The time T at which the security sound is automatically stopped is set to a time at which an occurrence of an emergency in a two-family house or the like can be known in all living parts and necessary actions can be taken, for example, 10 minutes. This time T is M
It is stored in the RAM (not shown) of the PU 64. That is, when a resident in a two-family house is changed, a new time for fully recognizing the occurrence of an emergency can be set (rewritten).

After setting this time T, the fire sensor 15a
Detects a fire, and the gas sensor 16a detects a gas leak, and when the emergency button 17a is pressed with a human finger, a high (Hi) level signal (hereinafter referred to as “Hi” level signal) shown in (a) of FIG. , And an emergency signal Sa) are output from the security control unit 18a to the MPU 64 in the main control unit 8 (step S11). In this case, the MPU 64 is monitoring the input of the emergency signal Sa (step S12). When the input of the emergency signal Sa is recognized in this step S12 (Yes), the MPU 64 subsequently determines whether the security sound is automatically stopped or manually stopped (step S1).
3).

When the automatic stop setting is recognized in step S13 (Yes), the MPU is activated at the rising edge of the emergency signal Sa.
64 sends out the pulsed security control signal Sb shown in FIG. 4B to the signal supply connection section 49 (step S).
14). Along with the transmission of the security control signal Sb, the MPU 64 controls the clock circuit 56 as shown in (d) of FIG. 4 to start clocking for a time T, which is 10 minutes in this example, and a flag (1 ) Is set, and the process proceeds to the next process (step S15). Next, the security sound signal generator 50 sends out the security sound signal Sc shown in (c) of FIG. 4 through the extension circuit 45 (step S1).
6). For example, an intermittent “woooooo” signal is transmitted through the extension circuit 45 to the module connector units 30a to 32.
a and the security telephone handsets 22a-23b,
Speaker 34a and security telephone subunits 22a-23
A security sound is issued from a built-in speaker (not shown) of b (step S17).

Next, the MPU 64 takes in the measured time when the flag (1) is set and judges whether or not the transmission of the security sound signal Sc has reached the time T (10 minutes). In other words, it is determined whether or not the continuation of issuing the security sound from the speakers of the module connector parts 30a to 32a and the security telephone slave units 22a to 23b has reached the time T (step S18). If the security sound signal Sc is not transmitted within the time T (10 minutes) in step S18, the process returns to step S15 to process the subsequent routines. That is, the timing of the timing circuit 56 and the transmission of the security sound signal Sc are continued until the time T is reached.

When it is determined in step S18 that the transmission of the security sound signal Sc has reached the time T (10 minutes) (Yes), the MPU 64 informs the signal supply connection section 49 of the security shown in (e) of FIG. A security control signal Sb for stopping the sound notification is sent (step S
19). At the same time, control is performed to stop the time measurement of the time T (10 minutes) in the time measurement circuit 56 (step S20). When the transmission of the security control signal Sb is stopped, the transmission of the security sound signal Sc from the signal supply connection unit 49 is stopped,
The notification of the security sound from the speakers of the module connector units 30a to 32a and the built-in speakers of the security telephone slave units 22a to 23b is also stopped (step S2).
1, S22). After this stop, the security telephone handsets 22a to 23b perform R processing by the processing of an internal CPU (not shown).
Read the character data of the character stored in OM,
A security sound is issued to the LCD 28a shown in FIG.
It is displayed that this notification was stopped at time T (10 minutes). For example, "We issued a fire security alert"
Is displayed (step S23). Note that it is advisable to display the alarm time together with this display. For example, “A.M.
○ The security warning of the fire was issued every minute. ”Is displayed.

Further, the LED 28b shown in FIG. 3 is made to blink under the control of an internal CPU (not shown) (step S2).
4). A red light emitting element is used for the LED 28b, and a blinking operation is performed, so that it is possible to visually and easily and quickly confirm the continuation of the alarm. During the screen display and the blinking display on the security telephone handsets 22a to 23b, the stop of the display is monitored by the MPU 64 in the main control unit 8 (step S25). This display is stopped by pressing the emergency notification stop button (not shown) of the keyboard 28d in the security telephone slave units 22a to 23b shown in FIG. 3 or pressing the emergency buttons 17a and 17b in FIG. 1 again. The MPU 64 judges this depression and instructs the security telephone slave units 22a to 23b to stop the display on the LCD 28a and the blinking of the LED 28b (step S2).
6). In the security telephone handsets 22a to 23b, when this stop instruction signal is input, an internal CPU (not shown)
Stop processing is performed under the control of (step S27).

If the automatic stop is not set in step S13 (No), the MPU 64 recognizes the manual re-pressing of the emergency buttons 17a and 17b through the security controller 18a (step S2).
8, 29). When the MPU64 recognizes the re-press (Y
es), the MPU 64 sends the security control signal Sb for stopping the issuance of the security sound to the signal supply connection unit 49 (step S30). When the transmission of the security control signal Sb is stopped, the transmission of the security sound signal Sc from the signal supply connection unit 49 is stopped, and the speakers of the module connector units 30a to 32a and the built-in speakers of the security telephone slave units 22a to 23b are stopped. The issuing of the security sound is also stopped (steps S31 and S32).

In this way, the program control process for detecting the fire, the gas leak, etc., and automatically stopping the alarm after a fixed time after issuing the security sound is completed, and the initial state is set. It will be in a standby state for the next processing start. As described above, in the first embodiment, a fire, a gas leak, or the like is detected, and the alarm is automatically stopped after a predetermined time has elapsed after the security sound is issued, so that the alarm is not unnecessarily prolonged.
Therefore, wasteful power consumption is eliminated, and false alarms for a long time are prevented from occurring, and for example, no nuisance is caused to residents in a two-family house with many residents.

Next, a second embodiment will be described. In the second embodiment, the emergency button pressing position in a two-family house having a plurality of emergency buttons installed, for example, a toilet call or bus call alarming place, can be easily identified depending on the alarming place. A security sound is issued with excellent sound quality, and in addition, a synthetic voice is used for notification. Figure 6

The U64 takes in the notification signal Se and determines which of the notification buttons 13a and 13b is pressed by the notification signal Se (step S42). Step S
When the notification button 13a is pressed at 42, that is, when the toilet call is made (Yes), the MPU 64 sets the signal supply connection section 49.
The security control signal Sb for toilet call is sent to (step S43). This security control signal Sb
Then, the security sound for toilet call from the security sound signal generation unit 50, for example, the security sound signal Sc of "security sound intermittent at low frequency" or "toilet call occurrence" by synthetic voice is supplied to the signal supply connection unit 49,
It is sent to the module connector units 30a to 32b through the communication path switch 48 and the extension circuit 45 (step S4).
4). If the notification button 13b is pressed in step S42, that is, if the call is a bus call (No), the MPU 64
Sends the bus call security control signal Sb to the signal supply connection 49 (step S45). With this security control signal Sb, a security sound for bus call from the security sound signal generating unit 50, for example, a security sound signal "interrupting at high frequency" or a security sound signal Sc of "bus call occurrence" by synthetic voice is connected. It is sent to the module connector units 30a to 32b through the unit 49, the communication path switch 48, and the extension circuit 45 (step S46).

This security sound signal Sc is issued from the speakers of the module connector parts 30a to 32a and the built-in speaker (not shown) of the security telephone slave units 22a to 23b (step S47). Next, MPU64
The signal for manually pressing the emergency buttons 17a and 17b is fetched through the security control unit 18a for determination (steps S48 and S49). If the MPU64 can recognize that the emergency buttons 17a and 17b have been pressed again (Yes), MP
The U64 sends the security control signal Sb for stopping the issuance of the security sound to the signal supply connection section 49 (step S50). When the transmission of the security control signal Sb is stopped, the transmission of the security sound signal Sc from the signal supply connection unit 49 is stopped, and the module connector unit 30a
~ 32a speaker and security telephone slave unit 22a ~
The issuing of the security sound from the built-in speaker of 23b is stopped (steps S51 and S52).

As described above, in the second embodiment, the sound quality corresponding to the location of the alert and the security sound of the alert status (high and low frequencies) are issued, and the notification is made by voice such as synthetic voice. It is easy to find the place where the notification button such as a toilet call or bath call is pressed in a household house.

The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and the design within the scope not departing from the gist of the present invention. Modifications are free and are included in the present invention.

For example, in the first embodiment, the time T at which the security sound is automatically stopped is set to the security telephone slave unit 22.
I set it from the keyboard 28d of a and 23a,
A keyboard is attached to the 64, and the time T
May be set. Further, the time T can be stored in an EEPROM or the like by an external device and mounted on the MPU 64. Furthermore, the fire sensors 15a, 15b,
As described with the gas sensors 16a and 16b, a person detection sensor that detects an intruder into the room by the Doppler effect of the reflected wave to the radiated burst wave, a magnet sensor that detects the opening of the door, and a vibration by the displacement of the piezoelectric element. An earthquake detection sensor etc. may be installed together. Further, the security sound from the security sound signal generation unit 50 issues an intermittent "woooooo sound", but it may be output as a synthetic voice. For example, if "emergency, emergency, fire occurrence", "emergency, emergency, gas leak occurrence", etc. are individually output as voices, the resident can more quickly determine the occurrence of an emergency situation. Further, in the first embodiment, the LCD 28a and the LEDs arranged on the security telephone slave units 22a to 23b.
In 28b, the continuation of the security sound is displayed after the security sound is stopped, but the individual LCD and L connected to the main control unit 8 are displayed.
You may make it display by ED.

In the second embodiment, the notification button 13a for toilet call and the notification button 13b for bath call are provided.
Although it has been described with two, three or more notification buttons can be arranged. For example, in addition to a toilet call and a bath call, a notification button for a bedroom call to be called from the bedroom can be additionally configured. Furthermore, FIG. 1 and FIG.
Although the configuration of the first embodiment shown in FIG. 6 and the configuration of the second embodiment shown in FIGS. 6 and 7 are separately configured and described, even if they are configured in one security system configured by combining them, It is possible to obtain the same effects as those of the first and second embodiments.

Furthermore, in the first and second embodiments,
It is possible to use the TV intercom and the intercom independently in the living part of the parent couple and the child couple in the two-family house, and to control them integrally. For example, when the chime button of one of the TV door phones 11a and 11b is pressed, both TV door phone monitors 2
It is also possible that a chime sound is emitted from 0a, 20b, and one of the TV doorphone monitors 20a, 20b that has started the response controls the operation. Further, one of the TV intercom monitors 20a and 20b which has started this operation may make an extension call to the other non-responsive TV intercom monitors 20a and 20b. In addition, in the first and second embodiments, the cordless handset is described as being divided into two-family houses of two tenants A and B, but a cordless handset of the same tenant as the tenants A and B is further added. Is also good. For example, a close couple,
It is also possible to apply to a three-family house where siblings live together.

[0042]

As is apparent from the above description, in the security system according to the first aspect, the time from the start of alerting of the occurrence of an emergency is measured, and when this time reaches a preset predetermined time. Since the notification of the occurrence of an emergency has been stopped, all security cordless handsets do not continue to be issued unnecessarily.For example, a security sound is emitted in a two-family home with multiple security cordless handsets. It is possible to prevent unnecessary power consumption in the information and prevent the unnecessary issuing of the security sound for a long time in the case of an erroneous information.

In the security system according to the second aspect, since the notification of the occurrence of the emergency is stopped after a predetermined time, the occurrence of the emergency is displayed by blinking, displaying on the screen, or both. After the news stop,
Residents can quickly and surely find this notification.

In the security system according to the third aspect, different alarm sound information is stored corresponding to each of the plurality of notification switches, and an emergency situation occurs based on the alarm sound information corresponding to the notification switch that is turned on. Since, for example, the sound quality of high and low frequencies and synthetic voice are notified, the resident can easily find out the alarm location where the emergency button is pressed in a two-family house in which a plurality of emergency buttons are installed.
