Abstract

PURPOSE:To improve service to a user by monitoring the whole of home security by one center. CONSTITUTION:If a fire sensor 16, a crime preventing sensor 17, and an emergency sensor 18 raise the alarms, a signal is sent to a security unit 12 through a connection device 13 to flicker or light the alarm indications or the like corresponding to respective sensors, thereby informing persons being at home of the abnormality by alarm tones and voice synthesized sounds. Further, a businessman is informed of the abnormality through a home controller 11, an NCU 7, and a telecontrol center 3 by automatic dialing. The security unit 12 immediately sensors the operation of each sensor to give an alarm even while the user uses a telephone set. Consequently, the abnormality is immediately recognized. The telecontrol center 3 cuts off the line to report the abnormality simultaneously with lighting of a patrol light.

is a patrol light that is installed in a position that can be seen from outside the entrance and is used to notify the outside of any abnormalities in the customer's home. Also,
The fire sensor 16 includes a fixed temperature spot type sensor (for example, detects at 70 degrees Celsius and is installed on the ceiling of the kitchen), a differential spot type sensor (for example, detects a temperature rise of 15 degrees Celsius or more for 1 minute). Smoke detectors (installed on the ceilings of ordinary rooms such as living rooms) and smoke detectors (installed on the ceilings of stairs, etc.) are used. The security sensor 17 is composed of a magnetic switch, a passive sensor, etc., and notifies you with an alarm sound and a voice synthesized sound when a window or door is opened. Security sensor 17 has ON type and O type.
There is an FF type, and the OFF type will alert you if the line is cut, but the ON type will not, so the OFF type is often used. Here, an OFF type security sensor is used.

When the customer presses the absence switch when the customer goes out, the remote switch 19 enters the alert mode and waits for a predetermined period of time (for example, 60 minutes).
If you close the front door and go out within seconds), the alarm will not be triggered. In addition, when customers return home, the front door may be opened for a specified period of time (for example, 6 pm).
If the at-home switch is pressed within 0 seconds), the alert mode will be canceled.

Patrol light 20 has fire sensor 16 and security sensor]

When each of the fire sensor 16, crime prevention sensor 17, and emergency sensor 18 generates an alarm, a signal is first sent to the security unit 12 via the connection device 13, and the alarm display corresponding to each sensor flashes or lights up. , to notify people at home of abnormalities using an alarm sound and a synthesized voice sound. Further, from the connection device 13 to the home controller 11. Telecontrol center 3 is notified to operator 1 by automatic dialing through NCU 7. Note that the security unit] 2 immediately detects the operation of each sensor and issues an alarm even when the customer is using the phone (in the case of crime prevention, the alarm is issued after 60 seconds). Therefore, abnormalities can be immediately known. Telecontrol center 3 immediately cuts off the line as soon as the patrol light turns on.

141. The operation of the sensor connection section 132 will be explained.

The fire sensor 16 and the emergency sensor 18 are directly connected to the sensor. The OFF type security sensor 17 is directly connected to the security unit.

When the fire sensor 16 and the emergency sensor 18 generate an alarm, the input becomes the input to the connection circuit 137 as it is, and is output to the security unit 12 to notify the person at home of the abnormality. On the other hand, it is also output to the home controller 11, and the home control center 11 reports the abnormality to the operator 1 through the telecontrol center 3 by automatic dialing via the NCU.

When the security sensor 17 generates an alarm, the signal is input to the security unit, and the lamp inside the remote switch flashes to enter the alarm mode.

If this state continues for 1 minute, the security unit will generate an alarm sound indicating that an abnormal situation has occurred and at the same time turn on the transfer signal.
shall be. By combining this transfer signal and alarm mode signal,
The transmission circuit operates, and the R relay is activated as a crime prevention abnormality has occurred. Then, the signal is output to the home controller 11 through the contact point of the R relay, and the above-described operation is performed.

The connection circuit 137 is provided between the various sensors, the home controller, and the security unit, and even if there are differences in the input voltages of the respective home controllers and security units, connection is possible through diodes.

When any one of the sensors in the patrol light control circuit 139 is activated (after one minute for crime prevention), a relay is activated and the patrol light 20 is turned on by the contacts (9, 13) of the relay. To turn off the patrol light 20,
This can be done by pressing a remote switch provided on the surface of the connection device 13 (when the sensor is restored).

Next, the operation of the NCU connection section 131 will be explained.

The detection circuit 134 is activated by pressing the remote switch 19.
A photocoupler detects whether the lamp in the switch is on or off, and the timer circuit 135, 136゜141 (IC4
011,4538).

After a certain period of time (for example, 2
seconds), activates the Z relay.

Then, it is output to the NCU 7 from the terminal boards B1 and B2. This will notify you of your absence and put you in alert mode.

In addition, after a certain period of time (for example,
2 seconds), operate the W relay.

Then, it is output to the NCU 7 from the terminal boards B3 and B4.

This will notify you that you are home and will cancel the alert mode.

Note that timer circuits 135 and 136 do not operate simultaneously.

Further, when the detection circuit 134 detects blinking of the lamp, the timer circuit 141 enters the alarm mode.

In the above-mentioned embodiment, since the connection device 13 is provided, connection adjustment and voltage adjustment of each device can be performed, so there is an advantage that safety is high and construction can be performed easily.

Furthermore, in the above embodiment, one operator (center) can monitor the overall home security of the customer's home 24 hours a day, improving the service. Furthermore, in the embodiment described above, since NRT is used, control can be performed without ringing the telephone bell, so there is no need to bother customers.

(Effects of the Invention) As described above, according to the present invention, overall home security can be monitored by one center, and services to users can be improved.

Further, by providing a connection device, connection adjustment of various sensors and adjustment of voltage supplied to each device are performed, so there is an advantage that general-purpose products can be used during installation work.
