Inputs the signals from the gas shutoff valve and the safety device to the house-side device, and consists of an input interface, a central processing unit, an output interface, a RAM for data storage, and a ROM memory control device for storing control procedures of the entire system. A device having an electronic control circuit, a public line L outside a house, and a telephone connected via the electronic circuit, wherein the electronic control circuit provides a security function means by input of an ignition signal of a gas appliance from the telephone. After detecting the open / closed state of the gas valve through the operating function means of the mechanism is configured to output the ignition command to the gas mechanism. .

By the above configuration, the remote monitoring apparatus of the present invention exhibits the following actions and effects.

A) When the gas mechanism is ignited by inputting to the telephone of an outgoing ship, the gas shutoff valve can be output after detecting the open / closed state of the gas shutoff valve. Can be.

B) When the gas mechanism is ignited by inputting to the telephone of an outgoing ship, when there is no abnormality by monitoring the safety device of the disaster prevention, when the gas shutoff valve is detected, the ignition command can be output to the gas appliance. Therefore, the gas shutoff valve can be inspected and the gas equipment can be operated by the telephone at the outside place.

EXAMPLE

The remote monitoring apparatus of the present invention will be described based on the embodiment shown in the drawings.

1 and 2 are block diagrams of the remote monitoring apparatus of the present invention. A is a remote monitoring device, 100 is a house-side device installed in a house, T ₀ is a telephone installed in the house, L is a public line of a telephone including an exchange system (telephone station), and T ₁ is a pushbutton dial telephone installed outside the house ( Push phone).

The housing side device 100 is a fire sensor (S ₁ ) for detecting a fire, a method sensor (S ₂ ) which is a normally closed non-voltage contact mounted on a window door, 0 volts when inoperable, 6 volts in normal state, and gas leakage. Information detection sensor group (hereinafter referred to as sensor group) (1), electronic control circuit (2), gas shut-off valve (3) and electric power of various safety devices with a gas leakage sensor (S ₃ ) generating an output of 12 volts. Power supply (100 V AC 50/60 Hz) for supplying power to the sub-controllers 45, 46, 47, and 48, which are outlet outlets of the various mechanisms 4 composed of the mechanisms 41 and 42 and the gas appliances 43 and 44 (5). It is composed of

The electronic control circuit 2 includes an input interface 200, a central processing unit 300, an output interface 400, a sensor group 1 which is a storage device for setting a set value of a change flow rate, a set voltage of a battery power source, and a set synthesized voice. RAM for converting data from the data into an electrical signal, and ROM, which is a storage device for control procedures of the entire system.

The input interface 200 includes a voltage-free input port 201, which is an input port of the fire sensor S ₁ and an anti-security sensor S ₂ , and an input port of the gas leakage sensor S3 ( 202 is installed. The central processing unit (CPU) 300 outputs the fire sensor S ₁ , the crime prevention sensor S ₂ , and the gas leakage sensor S ₃ from the input interface 200 by an input from the output interface 400. The security function means 301 for determining whether the signal is normal and the various mechanisms 4 are turned on and off by an input from the output interface 400, and the operation state of the various mechanisms 4 is turned on at the same time. And a speech synthesis function means 303 for inputting signals from at least one of the monitoring mechanism operation monitor function means 302 and the security function means 301, and synthesizing the input signals into speech. The central processing unit 300 has a gas shutoff function means 304 for turning off the gas shutoff valve 3 provided in parallel with these.

The output interface 400 includes a mode converter 401 for switching between the home mode and the outing mode by the occupant's manual, and the push phone T ₁ and the phone T ₀ when all the converters 401 are in the home mode. Is respondable and the receiving function means 402 for connecting the push phone T ₁ and the central processing unit 300 to input the outgoing signal of the push phone T ₁ when the mode converter 401 is in the outing mode. ) And a transmission function means 403 for outputting a transmission signal to the push phone T ₁ .

The operation of this embodiment will be explained by the flowcharts shown in FIGS. 3 to 5.

3 to 5 show an operation flowchart of the gas appliance ignition when the mode converter 401 is set to the outing mode.

The operator makes a call to the push phone T ₁ from the outgoing line (step 501), connects the public line L of the phone (step 502), and outputs a voice saying "I am out now" (step 503). ), It is determined whether a house password number (for example, "1", "2", "3", "*") is entered (step 504), and the password number is not entered (not correct). The air line L of the telephone is cut off (the push phone T ₁ is cut off), and the malfunction of the gas appliances 43 and 44 and the mischief of an operator other than the occupant are prevented (step 505). When the password is entered, it is determined whether the security check is OK (step 506), that is, whether the abnormal signal is input from the fire sensor (S ₁ ), the disaster prevention sensor (S ₂ ), and the gas leakage sensor (S ₃ ). Determine whether or not. When the security check is not OK, the process proceeds to step 519. When the security check is OK, the voice message "OK" is transmitted to the push phone T ₁ (step 507). It is determined whether at least one mechanism number (for example, "0", "4") of at least one mechanism operation has been input (step 508). When no mechanism number is input, the process proceeds to step 518, and the mechanism When the number is input, it is determined whether or not the on signals (for example, "0", "4", "1", "*") of the gas appliances 43 and 44 are inputted (step 509). When the gas appliances 43 and 44 are not turned on, the process proceeds to step 505. When the gas appliances 43 and 44 are turned on, the operating state of the gas appliances 43 and 44 is monitored (step 510), and the signal is converted to a voice of "no abnormality" or "abnormal occurrence" and the push phone T ₁ (Step 511), and then determine whether the security check is OK again (Step 512), proceed to step 519 when the security check is not OK, and when the security check OK, the gas shutoff valve (3) Is judged whether or not the door is open (step 513), and when it is open, it outputs an ignition command to the gas appliance 43, 44 and transmits a voice to the push phone T _{1 as} "valve open state ignition possible". (Step 514), mechanism operation is started. Start operation of the instrument when the instrument number is correct. At this time, for example, when the operation of the bath gas appliance is started, a voice of "Starting bath preparation" is transmitted to the push phone T ₁ (step 515).

When the valve is closed, the voice “Valve Closed, No Ignition” is transmitted to the push phone T ₁ (step 516), and then the push phone 571 is moved to step 505 when the handset is lowered, When the handset is not lowered, step 508 is reached. In step 518, the security code (for example, fire sensor: "0", "1", "*", security sensor: "0", "2", "*", gas leakage sensor: "0", " 3 "," * " When the security code is input, the output signal of the sensor is input (step 519), and then a voice of "no problem" or "problem" is transmitted to the push phone T ₁ (step 520). The flow advances to step 517. The gas shutoff valve 3 may be turned off by the abnormal input of the fire sensor S ₁ and the gas leakage sensor S ₃ to control the gas product in the house.

As a malfunction prevention function,

A) If there is no input for more than 15 seconds during all operations, the aerial line (L) is turned off.

B) In all actions, they will not be executed unless they are last entered with the "*" key.

C) In all cases, enter the code number or instrument number other than the setting twice to turn off the public line (L).

The gas shutoff valve 3 may be turned off by the input from the outside place. In this case, the flowchart is the same as the instrument operation flowchart.
