Description

Description: TECHNICAL FIELD The present invention relates to a remote control device that remotely controls an electric device or the like installed at a remote place using a telephone line.

<Prior Art> When a remote control device using a conventional telephone line is set to an out-of-home mode for remote control, when the telecontroller detects an incoming call, an "answer message" is sent, and then a secret code signal or the like. Decode the signal according to the operation procedure of the above, change the state such as running / stopping based on the command input to the connected terminal device, or confirm the state and give a response according to that operation with a voice synthesis sound. To send to the telephone line. The main function was so-called remote control.

On the other hand, in the above-mentioned conventionally proposed remote control device, if the out-going mode is set, a "answer message" is unilaterally sent to the incoming call.

There is no particular problem when remotely controlling or checking the status of electrical devices in the house, but if you do not want to answer the phone while at home due to bathing or other affairs, or if you do not want to answer the phone call, such as a nuisance call or a prank call If you don't want to answer the call by using it, you can set the telecontroller to the out-of-home mode for effective use, but on the other hand, when you want to make an emergency call from outside the house, Only the "message" was sent, and the people at home didn't understand anything.

In addition, even if a power outage occurs while you are out, if the power outage is restored when you return home, you cannot understand why the home equipment is not operating normally, and the operation status of the home equipment after the power is restored. Is not constant, and there is a risk of causing an abnormal situation if a home device that should be stopped is operating.

<Objective> In view of the above-mentioned problems, the present invention allows a family member or a close acquaintance (specific person) to perform a specific operation even when a person at home sets the telecontroller to the outing mode and uses the absence. By sending a signal in accordance with the procedure, the notification sound built into the telecontroller can be sounded for an arbitrary time to notify that it is a call from a specific person, and also to notify the occurrence of a power failure and to recover from a power failure. It is an object of the present invention to provide a remote control device that can stop by sending a stop signal from the telecontroller if there is an in-home device connected to the telecontroller that is in operation later.

First, when the telecontroller 3 is set to the outing mode by the at-home / going-out changeover switch 11 which will be described later, the telecontroller 3 enters a standby state.

Telephone 1 on the go, in which case the operation method varies depending on the type of telephone line, and DTMF (Dual Tone Multi Frequency)
In the method, that is, in the case of a touch-tone telephone line (hereinafter referred to as PB), the button operation of the telephone is performed, and in the case of the out-pulse method (dial line hereinafter referred to as DP), it is performed by operating the commander. The commander is a handy type operation device that acoustically generates a DTMF signal and sends the DTMF signal to the telephone line if an operation procedure is input, but it is well known and will not be described here.

Make a call to your home by operating the buttons on the handset 1 when you are out. This calling signal is applied to the telephone 3 connected in parallel with the telecontroller 3 through the telephone line 2, and the telephone 4 rings the calling signal to notify that the telephone call is coming. The telecontroller 3 detects an incoming call when the number of times of detecting the switching ringing tone is detected by the mode changeover switch 34, which will be described later, at an arbitrary set number of times. When the incoming call is detected, the telecontroller 3 is switched to the operating state (the going-out mode is set). The telephone line 2 is switched to an incoming state and the ringing sound of the telephone 4 is stopped. The telecontroller 3 sends an "absence message", and a voice synthesis sound indicating that the house is out and is absent, for example, an absence message such as "I am out now" is sent any number of times (two times in the present invention). To do. Other than the person who is trying to operate the terminal devices 7, 7 ', 8 etc. in the house, the other person who made the call turns off the telephone 1 knowing that the person is absent. The tele controller 3 returns to the standby state after an arbitrary time. A person who wants to operate a telephone device or the like in the home sends a personal identification number to the telecontroller 3 by operating a button on the telephone 1 after the absence message is sent. (In the case of the telephone 1 of the DP line, the commander acoustically sends the signal of the personal identification number.) The tele-controller 3 sends the personal identification number sent by the telephone 1 through the telephone line 2 and the personal identification number of the tele-controller 3 described later. It is confirmed whether the number set by the number setting switch 15 matches, and if they match, a "confirmation sound" (in the present invention, "ping pong" is used) is sent to the telephone line 2, and the telephone 1 confirms this. To be done. If the personal identification numbers do not match, an "answer message" is sent to the telephone line 2 once. A new personal identification number is input from the telephone 1 and the correct personal identification number is sent to the telecontroller 3. If the password is entered three times by mistake, the telecontroller 3 will return to the standby state and disconnect the telephone line 2 from the talking state. This is due to mischief, etc.
It works effectively in prohibiting the manipulation of etc.

After the personal identification numbers match and the "confirmation sound" is sent, the desired electrical equipment is controlled and the state is confirmed by operating the buttons of the telephone 1 according to the operation procedure. When the operation is finished, the telephone 1 is turned off or a predetermined signal is sent to put the tele controller 3 into a standby state. When the telephone 1 is turned off, the telecontroller 3 goes into a standby state after an arbitrary fixed time.

An amplifier unit 30 is composed of a filter unit which amplifies the voice transmitted from the voice synthesis LSI 29 and passes a required band. Reference numeral 31 is a signal output unit, 33 is an incoming call detection number setting switch, for example, the incoming call detection number setting switch is set to 3 or 7, and 34 is a static (S) or signal depending on the device 7 ″, 7 ″, 8 ′ to be controlled. To a pulse (P) state, and a notifying unit 35 for notifying a call of a specific person (private call) into the house.

If the at-home / out-home change-over switch 11 is now at home, the microcomputer 10 reads it and enters the at-home mode. Home lamp
17 is turned on, and in this case, the microcomputer 10 closes the relay 32 on the side of the incoming detection unit 27 and the contact 31a. The ringing tone from the telephone line 2 is added to the incoming call detection unit 27 via the line connection unit 26, but even if an incoming call signal is added to the microcomputer 10 from the incoming call detection unit 27, the microcomputer 10 is in the home mode. The tele-controller 3 continues the standby state. Remote control is not possible. In this case, the telephone set 4 continues to ring until a ringing tone is answered by the telephone set 4.

Also, when this home mode is set, the tele controller 3 is operated by operating the device switches 12, 13, and 14.
It is possible to control 7 ″, 7 ″, 8 ′, etc. and 8 ′ electric devices connected to. In addition, the operating state is the operating lamp 18,1

When the device switch 12 is operated, the microcomputer 10 reads this state and sends a control signal to the output unit 31. Signal line 6 ',
6 "and 6 are composed of a 4-core cable, two of which are used for control signals and the other two for status confirmation signals.
The control signal sent from 10 is amplified by the output unit 31 and sent to the signal line 6 via the terminal block 24. This signal is sent via the relay adapter 9 to the electric devices 7 ″, 7 ″ with HA terminals equipped with a microcomputer. In a power control type electric device 8'such as a lighting fixture, an outlet adapter 8 having a built-in relay (not shown) for directly controlling the power ON / OFF is controlled by a command from the telecontroller 3, and the result is sent to a signal line. Send out. This status signal is input to the microcomputer 10 via the output unit 31, and the microcomputer 10 lights the corresponding lamps of the equipment operation lamps 18, 19, 20 according to the status of the electric equipment 7 ″, 7 ″ or the outlet adapter 8. Or it will be turned off.

That is, it has the function of centralized remote control in the house.

Next, when the at-home / going-out changeover switch 11 is switched to going out, the microcomputer 10 enters the going out mode. The at-home display lamp 17 is turned off and the out-home display lamp 16 is blinked (in the present invention, it is turned off for 1 second, 0.5
Illuminated for a second and indicated as a slow blink.)

When a call signal from the telephone line 2 is detected in this state, it is further added to the incoming call detection unit 27 from the line connection unit 26, converted into an incoming call signal by the incoming call detection unit 27, and the microcomputer 10
Added to.

When the incoming call detection unit 27 detects the number of times determined by the incoming call detection number setting switch 33, the microcomputer 10 relays 32
Operate and close contact 31b side. At the same time, the going-out display lamp 16 is made to blink to indicate that a call is being received (in the present invention, this is indicated as blinking at 0.5 second intervals-fast blinking). Microcomputer 1
0 sends a signal to the voice synthesis LSI 29, and the voice synthesis LSI 29 sends an answer message. The voice signal amplified through the amplifier section 30 is sent to the telephone line 2 through the coupling transformer 26T, and the answering message can be confirmed by voice to the partner telephone 1.

In this state, if the telephone 1 at the destination is cut off or no DTMF signal is input subsequently, after an arbitrary time (30 seconds in the present invention)
To disconnect the telephone line 2. That is, the microcomputer 10 stops the operation of the relay 32 and closes the contact 31a.

After the sending of the answering message is completed (within the present invention, within 30 seconds), the personal identification number is input by the button operation from the telephone 1 at the destination. This signal is sent from the telephone line 2 by DTMF, amplified by the amplifier section 30 through the coupling transformer 26T of the line connection section 26, and sent to the tone decoder 28.
The tone decoder 28 converts the DTMF signal into a digital signal and inputs it to the microcomputer 10. The signal of the personal identification number, the number determined by the personal identification number setting switch 15 and the microcomputer 10 are compared, and if they match, the voice synthesis LSI 29
To send a "confirmation sound". Amplification is performed by the amplifier unit 30 and a "confirmation sound" is sent to the telephone line 2 via the coupling transformer 26T. After confirming this recognition sound, the number corresponding to the desired electric equipment 7 ″, 7 ″ or outlet adapter 8 etc. (Because the number of points that can be controlled is three in the example of the present invention, Button) is operated from the telephone 1 at the destination. Then, whether to run or stop the device or check the status, for example Operate the button. [In the present invention, continue Enter. This signal is applied to the microcomputer 10 in the same manner as the personal identification number signal, and the microcomputer 10 sends a control signal to the output unit 31 according to the input signal. It is sent to the electric equipment 7 ", 7" or the outlet adapter 8 or the like via the signal lines 6 ', 6 ", 6 and the state of the electric equipment 7", 7 "or the like changes according to this signal. A status signal is sent back from the equipment 7 ", 7" or the outlet adapter 8 or the like, input to the output unit 31 and further applied to the microcomputer 10. The status signal is sent to the microcomputer.
10 confirms and sends a signal to the voice synthesis LSI 29 in order to send a voice synthesis response corresponding to the confirmation. This voice is sent to the telephone line 2 in the same manner as the above-mentioned absence message and is sent to the telephone 1
You will be able to confirm by voice. After confirming on the telephone 1 side, if the telephone 1 is turned off, the microcomputer 10 opens the telephone line 2 after 30 seconds.

The operation of the relay 32 is stopped and the contact 31a is closed. In the present invention, the defined code is also If you input, the telephone line 2 will be opened immediately upon receiving this signal.

It should be noted that until the ringing tone is detected, the telephone 4 sounds the ringing tone and if the user takes the handset of the telephone 4, the telephone call can be made as usual, but the telecontroller 3 does not respond.

Also, if you forget to switch the home / out-home switch 11 to the outside, such as when you suddenly go out, if you call the phone for a long time (for example, ring the bell 15 times), you can switch to the outside mode only once and You can control it.

When the user forgets to switch the at-home / going-out changeover switch 11 to going out, the number of detections at the time of call detection is only 15 times, and other operations are 3 to 3 times at the time of going out mode.
It is the same as 7 times. This feature is very effective and convenient. This becomes the going-out mode only once, and when the telecontroller 3 is released from the telephone line 2, it returns to the home mode.

In the above-mentioned configuration and operation, the setting of the personal identification number and how to use the at-home / out-home changeover switch 11, the device switches 12, 13, 14 etc. will be described a little further.

First, to set the security code, unplug the AC adapter 5 of the telecontroller 3 from the power outlet and rotate the knob of the security code setting switch 15 provided on the back of the telecontroller to rotate the knob of the security code 15 The password is set according to the personal identification number, and when the personal identification number is set, the AC adapter 5 is plugged into a power outlet to energize, and the telecontroller 3 is set at a predetermined position. Similarly, when changing the personal identification number, the knob of the personal identification number setting switch 15 is rotated in accordance with the changed number. Also in this case, before changing the AC adapter 5
After disconnecting from the power outlet, change it and insert the AC adapter 5 into the power outlet.

At-home / out-home changeover switch 11 turns on at-home display lamp 17 to indicate that it is at-home switching,
When you switch to going out, the go-out display lamp 16 blinks to indicate that you are going out, and you can switch between home / going out alternately. When you switch to home, you cannot perform tele control, but the device switches 12, 13 Up to 3 devices can be started / stopped by 14 and 14.

Then, if you switch to going out, you can use the telephone 1 for tele control from the place you go, but the device switches 12, 13, 14
The device cannot be controlled by. In this case, when the operation display lamps 18, 19, 20 are lit, the device is in the operating state, and when it is off, the device is in the stopped state. Also equipment switch 12,13,
No. 14 operates for the first time by pressing and holding for about 1 second until a key touch sound is heard, and a delay time of about 1 second is provided for safety so that the switch will not turn on even if you touch it for cleaning. Is.

And when I go out
Press the go-out switch 11 to go out and put the tele-controller 3 in a standby state. In this state, when a call comes in while out of the house, a ringing tone is detected and an absent message is automatically sent (the absent message is repeatedly sent twice). The number of times the ringing tone is detected can be selected from three times or seven times by the incoming call detection number setting switch 33 on the back side. Then, after sending the absence message, the telephone line 2 is disconnected after about 30 seconds. When performing tele control, the PIN code must be entered within this time.

When returning home, the at-home / out-home changeover switch 11 is pressed to return to the at-home mode and the telephone is used as before, and the tele-controller 3 is disconnected from the telephone line 2. If the user forgets to switch to the home, the absence message is transmitted when the ringing tone (3 to 7 times) is detected, and the telephone line 2 is disconnected after 30 seconds.
If the call is answered within this time and the at-home / out-home changeover switch 11 is returned to the home, the call can be made unless the other party hangs up.

To perform telecontrol from outside, use a touch-tone phone and follow the procedure below.

Specific person selection function (private call) When it is not desired to answer a telephone call by using the absence as described above, the at-home / out-home switching switch 11 is switched to the out-going state and the microcomputer 10 is set to the out-of-going mode. If there is an incoming call in this state, the incoming call is detected as described above, and the microcomputer 10 sends an answer message to the telephone line 2 through the voice synthesis LSI 26 and the amplifier 30 coupling transformer 26T. It is very effective for countermeasures against nuisance calls, prank calls, etc., but it also prevents all emergency calls from family members, acquaintances, and other specified persons. In this case, after confirming the two digits below the PIN code or the "confirmation sound" after entering the PIN code by the method described below, press the button on the telephone 1 Enter. The microcomputer 10 decodes this signal and activates the notification unit 35 to notify that the call is from a specific person. By taking the handset of the telephone 4 and switching the home / out-home switching switch 11 to home, the telephone 4 can be used to talk with a specific person.

In the present invention, the microcomputer 10 opens the telephone line after 60 seconds if the telephone is left unresponsive. For how to use private call, follow the above PIN In addition to the case of inputting, tell a specific person, such as a close friend, the lower two digits of the personal identification number. There are two ways to enter.

To use private call, first make a call to your home with the telephone 1 at the destination, confirm that the tele controller 3 has sent out the absent message, and about 1 second after the absent message ends, enter the PIN code. After confirming the confirmation sound “Ping Pong” by typing Enter. At this time, a specific person such as a close friend inputs the two digits below the personal identification number instead of the four digits of the personal identification number. Then, the telecontroller 3 sends a "ping pong" sound to the telephone line at intervals of about 1 to 2 seconds, and the piezoelectric buzzer built in the telecontroller 3 informs the informing section 35 that the call is from a specific person. Then, by picking up the handset of the telephone 4, switching the at-home / out-home changeover switch 11 to at-home and disconnecting the tele-controller 3 from the telephone line, a telephone call can be made. In the above case, if left unattended while the call from the specific person is being notified, the tele controller 3
Automatically disconnects the telephone line and stops the sending of "ping pong" and the alarm sound.

In the above operation, when there is a power failure (when 100V AC fails), even if the home / going out change-over switch 11 is set to go out, the telecontroller 3 is disconnected from the telephone line 2. , Telecontrol is not possible. When a call is received during this power failure, the telephone 4 can be used as usual. When the power failure is restored, telecontrol can be performed by switching the home / going out switch 11 to going out, and at this time, going out indicator lamp
Remember that there was a power failure with 16 lit. Then, the device connected to the tele-controller 3 sends a signal for stopping for safety. The going-out indicator lamp 16 can be turned off by operating the home / going-out switch 11.

<Effects of the Invention> Since the remote control device of the present invention is configured as described above, even if the home device is stopped due to a power outage without knowing it, a power outage occurs due to continuous lighting of the outing display lamp. In addition to notifying the fact, if there is an in-home device connected to the telecontroller after the power is restored, a stop signal can be sent to stop the operation and prevent an abnormal situation from occurring.
