BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a preferred home security system of the present invention will be described with reference to FIG. Fig. 1 shows an overall home security system that employs a control device and operation of home appliances for home security systems in ordinary homes and offices, as well as constantly monitoring gas leaks, water leaks, intrusions of suspicious persons, and the like. It is the block diagram which showed. First, in the home security system according to the present embodiment, various alarm sensor groups 1 are arranged in each room. For example, a crime prevention sensor 11 that senses vibrations
(1-N), not a sensor, but a nursing care emergency button 1
2, earthquake sensor 13, multiple (1 ~ N) heat sensor 14 arranged in each room, similarly, multiple (1 ~ N) smoke sensor 15,
A plurality (1 to N) of carbon dioxide sensor 16, a plurality (1 to N) of carbon monoxide gas sensor 17, and a gas leak sensor 18 such as city gas or propane gas supplied from a gas company are connected to the controller 2, When these detect an abnormal state, the sensor network control device 21 of the controller 2 converts these abnormal signals into identifiable signals, which are transmitted from the protocol conversion device 22 of the controller 2 to the communication means 3. Specifically, it is transmitted to the packet delivery (IP) means 31 between the internets that constitutes the communication means 3, and then normally connected to the internet connection means 33 side by the circuit selection device 32 and always connected through the router 34 to the ADSL. Line 35
(Asymmetric Digital Subscriber Line) or the like is connected to the Internet always-connected line, and connected to the Internet network 36. In addition, as an Internet constant connection line,
In addition to the above-mentioned ADSL line 35, a line using an optical fiber line or a wireless type may be used, and another form may be used as long as it is a line that can be always connected.

Here, the ADSL line is connected to the circuit selection device 32, the internet connection means 33, the router 34 and the ADSL line 35, and the ADSL line is defective due to some reason such as a router failure or a line disconnection in the connection line to the internet network 36. In the event of an emergency in the event of an occurrence, the circuit selection device 32 detects this defect and immediately switches automatically by the dial-up connection means 37, and packet delivery (IP) means between the Internet.
The signal from 31 is connected to the dial-up destination designated in advance from the public telephone line 38, and is connected to the Internet network 36 via the provider 39. Various information from the Internet network 36 is temporarily stored in the server management center 51, which is the information sender / receiver 5, and if necessary, a care / medical center 52, general users 53 such as subscribers and their families, and a security guarantee center 54.
Call. At this time, information is provided from the server management center 51 in various formats such as voice notification and data information transmission as required, and the care / medical center 52 and the security guarantee center 54 provide general users 53 Also report this information. In addition to the controller 2, the public telephone line 38 is connected to a telephone terminal or the like as needed.

Here, the controller 2 is provided with a central control unit 24, and the central control unit 24 controls an electric equipment group 4 called a home electric appliance, and the electric equipment group 4 includes a lighting 41 and a television. There are AV equipment 42 such as video and video, a refrigerator 43, an air conditioner 44, and a bath water heater 45, which control the operating state and operating time of these, and further, the sensor network control device 21.
Although the settings and operating states of the computer are also taken in and processed, a computer terminal device 241 such as an input / output device and a display device is provided for these control settings, and the control content is set as necessary. The central controller 24 and the terminal device 241
Was built in the controller 2, but it may be a normal notebook computer connected to the outside of the controller 2. Then, the control information of the central control unit 24 is transmitted to the communication means 3 and connected to the Internet network 36, and conversely, if necessary, an external information transmitter / receiver 5, a care / medical center 52, the subscriber himself / herself, or the like. From the general user 53 such as family members and the security protection center 54, the controller 2 has an operation means for operating the central control device 24 from the outside, which is incorporated in the central control device 24, and the electric power is supplied in the same manner as the terminal device 241. The device group 4 can be controlled.

On the other hand, the sensor network control device 21 of the controller 2 converts the abnormal signal into a signal that can be identified and sends it to the sensor signal selector 23. In the sensor signal selector 23, the alarm signal from the alarm sensor related to the fire is sent. Signal, in the present embodiment, the seismic sensor 13 with the reference symbol A, a plurality (1 to N) of thermal sensors 14 arranged in each room, and a plurality of (1
~ N) smoke sensor 15, multiple (1 ~ N) carbon dioxide sensor
16, select an abnormal signal of a plurality (1 to N) carbon monoxide gas sensor 17, gas leak sensor 18 such as city gas or propane gas supplied from a gas company. Here, the "signal from the alarm sensor related to the fire" in the present invention is a sensor group which is considered to be related to the fire indicated by the symbol A in FIG. 1 in the present embodiment, but in some cases, the fire may occur. It is possible to select not only all of the alarm sensors related to the above, but only any of them, for example, only the thermal sensor 14 arranged in each room or the thermal sensor 14 arranged in each room. Only the smoke sensor 15 is enough,
In any case, it is shared with the home security system. On the contrary, since it is shared with the home security system, the output signal from each sensor may be analyzed, and the detection level for notifying the user and the detection level for outputting the gas cutoff signal may be different, for example, The seismic intensity of the earthquake sensor 13 is 2 and the signal level of gas cutoff is 3 or more when the seismic intensity is 3 or higher.
Alternatively, the operation signal may be output to shut off the gas, or vice versa.

Further, even if it is not directly related to a fire, a gas leak related to a gas appliance is dangerous to human life, so that an abnormal signal of the gas leak sensor 18 is also related to a fire in this embodiment. Treated as a signal from the alarm sensor. Then, when the selected abnormal alarm signal is output from the sensor signal selector 23, this signal is input to the gas circuit breaker 61 of the gas meter 6 and immediately operates the gas circuit breaker 61 to cut off the gas. In addition, the information that the gas is shut off is sent to the network controller.
(NCU) 7 and converts it into a transmittable signal with an identification signal and sends it to the central gas monitoring device 8 via the public telephone line, where (1) user selection recognition, (2) Recognition of fire occurrence, (3) presence / absence of gas cutoff, (4) presence / absence of gas leak are discriminated, and the gas management center 9 is notified as necessary. Information and operation can be performed bidirectionally between the gas management center 9 and the gas meter 6, and by operating the gas management center 9, the gas circuit breaker 61 of the gas meter 6 can be operated to interrupt the gas.

Since the present embodiment is configured as described above, it is possible to set the operation of the electric equipment of the home electric appliances with the terminal device 241, and also the general users such as external subscribers themselves and their families.
From 53, the care / medical center 52, and the security guard center 54, the electric device group 4 in the home can be controlled at all times by an ordinary notebook computer or the like as in the terminal device 241. Also, an AD that is always connected as an Internet permanent connection line
Since the SL line is used, the cost can be reduced, and if a problem occurs in the ADSL line that is always connected to the Internet, a circuit selection device that detects this and automatically switches is provided, and the public telephone line is immediately dialed up. Security is guaranteed because you connect to and connect to the server management center. Furthermore, when an abnormality is detected in one of the groups A of the alarm sensors 13 to 18 related to the fire, the gas in the gas meter 6 is automatically shut off immediately, and at the same time, the user 52 and the security guarantee center 53 are notified. Therefore, the fire can be prevented in advance, and the damage can be minimized even when the fire occurs. Further, it is not necessary to operate the gas circuit breaker 61 at the security guarantee center or the gas management center, and the maintenance is simple. That is, conventionally,
When the heat sensor 14 or the like detects an abnormality, the controller 2 notifies the security guard center 54 of this, and when the security guard center 54 determines that the gas pipes are dangerous, the controller 2 notifies the gas control center 9 of the gas. Since the gas breaker 61 of the gas meter 6 is actuated by the operation from the management center 9 to shut off the gas, the gas shut-off operation will be delayed compared to the present embodiment even in the prevention and extinguishing of an urgent fire. However, in the present embodiment, these disadvantages are improved.

Needless to say, the present invention is not limited to the above-mentioned embodiments as long as the characteristics of the present invention are not impaired. For example, it goes without saying that the sensor 1 and the controller 2 may be connected wirelessly such as wirelessly.
Further, the connection of the user may be a wireless connection such as a mobile phone. Further, the central controller 24 and the terminal device 241
Is incorporated in the controller 2, but it may be an ordinary notebook computer or desktop computer connected to the outside of the controller 2.
