BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a home security system suitable for multi-family residences in which each household is equipped with a home security device that receives information from various sensors and issues an alarm.

0002

2. Description of the Related Art In recent years, home security devices that are connected to sensors such as fire sensors, gas leak sensors, security sensors, etc. and have a function of quickly notifying the surroundings of abnormal conditions in the home have become widespread. Furthermore, with the increase in the number of multi-family residences in which multiple households live together in one housing unit, home security devices are increasingly being installed for each household.

[0003] In this case, each home security device uses only one sensor line according to the Ministerial Ordinance stipulating technical standards for receivers in the Ordinance of the Ministry of Home Affairs, due to price and system scale. It is not possible to share the monitoring area of each other's sensors, and each household has a separate system, and each system can only output the alarm sound and stop the alarm sound by directly operating the home security device. was possible.

0004

[Problems to be Solved by the Invention] In such conventional home security devices installed in multi-family residences, each household has a completely different system even though it is in one building, and if one home security device Even if the security device detects an abnormal condition, there is a problem in that the information cannot be transferred to systems installed in other households.

[0005] In addition, in conventional home security devices for multi-family residences, the alarm sound can only be stopped from the main body of the device, so if you do not go to the place where the main body of the home security device is installed, the alarm will not be activated. There was a problem with not being able to stop the sound.

[0006] The present invention was devised to solve such conventional problems, and when any one of a plurality of home security devices detects an abnormal condition, the device is installed in all households. The alarm sound is transferred to the home telephone system installed in the building, and information within a single building can be shared.
The purpose of the present invention is to provide an excellent home security system that can immediately confirm and stop the transmitted alarm sound using a nearby home telephone device.

[0007]

[Means for solving the problem] (a) An acoustic output circuit to which a sensor such as a fire sensor, gas leak sensor, or security sensor is connected and outputs an acoustic signal when the sensor detects an abnormal condition, and this acoustic output circuit. A plurality of home security devices each including a sound generating device driven by the output of the circuit and a control means for forming a command to output an alarm sound;
b) a plurality of home telephone devices provided with a sound generator driven by the output of the sound output circuit of the home security device and means for forming a command to stop the alarm sound;
(c) a home bus that commonly connects the plurality of home security devices and the plurality of home telephone devices;
It is equipped with a line.

[0008]

[Operation] When an abnormal condition is detected in any home security device, an alarm sound is generated from the sound generator of the detected home security device, and a command to output the alarm sound is sent, and the home bus An acoustic signal is output through the line extension, and an alarm sound is generated from each home telephone device. When an alarm sound stop key of the home telephone device is operated to send a command to stop the alarm sound while the alarm sound is being generated, the acoustic signal being generated by the home security device is stopped.

[0009]

[Embodiment] As shown in FIG. 1, the home security system connects a home bus controller 6 to a home bus line 4 that is commonly wired to each household.
5n and home security devices 1a to 1n are connected, and sensors 2 such as a fire sensor 21, a gas leak sensor 22, and a security sensor 23 are connected to each home security device 1a to 1n. The home bus controller 6 is connected to the office line 9.

As shown in FIG. 2, each of the home security devices 1a to 1n has a sensor input detecting section 8 connected to the sensor 2, and the output of the sensor input detecting section 8 and the output of the address setting section 13 are inputted thereto. a main control section 7, a display section 12 and an audio output circuit 1 connected to the main control section 7;
1, a sound generator 10 driven by the sound signal from this sound output circuit 11, a home bus extension line connection section 16 that transmits the output of this sound output circuit 11 to other home telephone devices 5a to 5n, and a main Control unit 7 and home bus
It is provided with a home bus data interface 14 for transmitting and receiving data to and from the line 4 and a connection section 15 thereof.

Next, the operation of the home security system configured as described above will be explained based on a flowchart.

Step 1: For example, when the sensor 2 connected to the home security device 1a detects an abnormal state, the sensor input detection section 8 detects this abnormal state and transmits it to the main control section 7. Step 2: The main control section 7 detects the abnormal state. When the control unit 7 confirms the operation of the sensor 2, it immediately operates the display unit 12 to display the occurrence of an abnormality, and at the same time, in step 3: transmits the acoustic output signal generated in the acoustic output circuit 11 to the acoustic output signal of the main body 1a. The signal is output to the device 10 to generate an alarm sound. Note that the alarm sound emitted by the sound generating device 10 of this main body 1a may be transmitted to other home security devices 1b to 1.
It has no effect on n.

Step 4: At this time, the home security device 1a determines whether to issue any notification to the other home security devices 1b to 1n via the home bus data interface 14 and the home bus line 4. Send a command to query. and,
When the other home security devices 1b to 1n receive a command indicating that they are in a standby state without issuing an alarm, the process moves to step 6.

Step 5: When a command is returned indicating that the other home security devices 1b to 1n are issuing alarms, the priority order of the alarm contents is checked and the alarm contents of the other home security devices are checked. Step 6: The main control unit 7 also outputs the audio output signal of the audio output circuit 11 to the home bus extension line connection unit 16, and the main control unit 7 via the bus data interface 14 to the home bus controller 6;
A command to use the extension line of home bus line 4 is sent.

Step 7: Upon receiving this command, the home bus controller 6 connects the extension lines of the home telephone devices 5a to 5n to the extension line of the home bus line 4. Step 8: An alarm sound is generated (issued) from each home telephone device 5a to 5n.

Step 9: Home security device 11
If a higher priority alarm is generated from another home security device 1b to 1n in step 5 while the home telephone device 5a to 5n is outputting the alarm content of Since the security device sends a command to inquire about what alarm is being issued, the home security device 1a outputs the contents of the alarm that is currently being issued to the home bus line 4, and also outputs an acoustic output. The acoustic output signal generated in the circuit 11 is separated from the extension line of the home bus 4.

Step 10: During the alarm sound, for example,
When the home telephone device 5a presses the alarm stop key 3 to send an alarm sound stop command to each of the home security devices 1a to 1n, Step 11: The own home security device 1a is issuing the alarm with the highest priority. If so, at the same time as receiving that command, it is determined that there is an input to stop the alarm sound, and step 12: The alarm sound is stopped and a stop command is sent to the home bus line 4 for this alarm. Note that the home security devices 1b to 1n that are not outputting an alarm sound or emitting an alarm sound that is not the highest priority ignore the alarm sound stop command from the home telephone device 5a.

Step 13: Even if the home security device 1a that issues the alarm with the highest priority issues a command to stop the alarm sound, the other home security devices 1b to
If an alarm has been issued within 1n, return to step 4.
When the command is received, the alarm is output to each home telephone device 5a to 5n in the same manner as when a new alarm occurs, and the alarm sound is switched to the alarm sound having the next highest priority.

[0019] If the home security device 1a that is issuing the highest priority alarm is also issuing other alarms at the same time, the highest priority alarm will be stopped and at the same time when a new alarm occurs. Similarly, each home telephone device 5a
-5n, and then switches to the next highest priority alarm sound.

[0020] Such home telephone devices 5a to 5n
The operation to stop the alarm sound from the home telephone devices 5a to 5
This can be repeated as many times as necessary until the alarm sound is no longer output from n.

[0021] Since each home security device 1a to 1n is provided with an address setting unit 13, by setting a different address that does not overlap with each other,
It is possible to identify which home security device issued the command. If you accidentally set a duplicate address, the second home security device will not output to the home telephone devices 5a to 5n.
It can be easily detected during construction testing.

[0022]

[Effects of the Invention] As is clear from the above description of the embodiment, by connecting a plurality of home security devices via a home bus line and communicating commands, any one of the home security devices can issue an alarm. It is possible to output an alarm sound to multiple home telephone devices connected to the home bus line, and to stop the alarm sound on each home telephone device. An excellent effect can be achieved in that alarm information can be shared in people living together in a house.
