More specifically, the present invention relates to a remote control device for Baum automation, which allows electrical equipment connected to the control device to be controlled from an external telephone.

<Prior art> In the conventional remote control device of this type, when an incoming call from outside is detected in the out-of-home mode for remote control, it sends out an “absence message” and then sends a sent PIN code signal, etc. Deciphers the signal according to the operating procedure and operates the connected terminal device based on the human-powered signal.
While performing control such as stopping or changing the state, the operating state of the terminal equipment is checked, and a response corresponding to the operating state is sent to the telephone line as a synthesized voice.

<Problem to be solved by the invention> By the way, in such a conventional remote control device,
When you return home from outside, you can use remote control from an external phone (
Whether telecontrol (hereinafter referred to as "telecontrol") was performed correctly could be confirmed simply by looking at the operating status of the actual equipment. Furthermore, telecontrol is not limited to one's own person; it can also be performed by a member of the family who is away from home, and there is a possibility that someone else may be able to telecontrol the user if the password is compromised. In that case, it was not possible to confirm with certainty whether someone other than himself was telecontrolled.

Therefore, the purpose of the present invention is to be able to tell whether or not the equipment is being telecontrolled without looking at the actual operating state of the equipment, and to ensure that the user is aware of the telecontrol if someone other than the user is telecontrolling the equipment. The object of the present invention is to provide a remote control device that can eliminate the above concerns.

Means for Solving the Problems> In order to achieve the above object, the first invention provides a device that is connected to a telephone line and also connects a terminal device, and receives a predetermined command signal sent via the telephone line. The above-mentioned command signal received by a remote control device configured to receive and control operation, stop, change of state, etc. of the above-mentioned terminal device, and to send a signal representing the state of the above-mentioned terminal device to the above-mentioned telephone line. The present invention is characterized by comprising display means for displaying the contents of the command.

Further, a second invention is a method for connecting a terminal device to a telephone line, receiving a predetermined command signal sent via the telephone line, and controlling the operation, stopping, or status of the terminal device. In a remote control device configured to control changes, etc., and to send a signal representing the state of the terminal device to the telephone line, the remote control device includes a timekeeping means, the command content of the received command signal, and the reception of the command signal. The present invention is characterized by comprising a memory for storing the date and time of the event, and a display means for displaying the contents stored in the memory.

5 is an AC adapter that supplies power to the telecontroller 3. This AC adapter 5 is plugged into a 100V-AC power outlet,
This AC power is converted into DC power necessary for the telecontroller 3. Furthermore, 6°, 6'', and 6°'' are signal lines connected to the telecontroller 3.

The signal line 6' is connected to the r-t via a relay adapter 9.
A (Home Automation) An electrical device with a terminal (for example, an air conditioner) 7 is connected. This electrical equipment 7 receives signals from the telecontroller 3 and performs operations such as starting/stopping. The relay adapter 9 uses a photocoupler to electrically isolate the telecontroller 3 and the electrical equipment 7. This relay adapter 9 can also be built into the electrical equipment 7.

Further, an electric device 8'' is connected to the signal line 6'' via an outlet adapter 8.The electric device 8'' is operated/operated by direct control of the power source such as a power control device, lighting, N power-tens, etc. Electrical equipment that can be stopped or its status changed. The outlet adapter 8 is for controlling this power supply, and has the same isolation function as the relay adapter 9.

Further, an air conditioner adapter 7° is connected to the signal line 6''.

Next, regarding the case of remote control, an outline of an example of use will be explained based on the above-mentioned Fig. 1-2.

First, when the telecontroller 3 is set to an out-of-home mode using a home/outside changeover switch 11, which will be described later, the telecontroller 3 enters a standby state.

In this case, the telephone 1 outside the home operates differently depending on the type of telephone line.
In the case of a telephone line (hereinafter referred to as PB), this is done by operating a button on a telephone, and in the case of an outpulse method (dial line, hereinafter referred to as DP), this is done by operating a commander. This commander is a well-known hand-held operating device that can acoustically generate a DTMF signal and send it to a telephone line by inputting operating procedures, and its explanation will be omitted here.

Now, when you make a call home by pressing a button on the telephone 1 when you are away from home, a ringing signal is applied to the telecontroller 3 and the telephone 4 connected in parallel through the telephone line 2, and the telephone 4 makes a ringing tone and the call is answered. Let me know what happened.

When the telecontroller 3 detects this call signal an arbitrary set number of times, it detects an incoming call. When an incoming call is detected, the telecontroller 3 switches to an operating state (becomes an out-of-home mode). Then, the telephone line 2 switches to the receiving state,
The ringing of the telephone 4 stops. Next, the telecontroller 3 sends an "away message" and sends out a voice synthesized voice indicating that the home is out of the home, such as "I'm out of the house", an arbitrary number of times (in this embodiment, 2 times). (times)). If the person making the call is someone other than the person who is attempting to operate electrical equipment 7.7', 8°, etc. in the home, the person will listen to the above message, know that he is away, and hang up the telephone. Then, the telecontroller 3 returns to the standby state after an arbitrary period of time.

On the other hand, if the person making the call is someone who is trying to operate electrical equipment in the home, after listening to the above-mentioned answering message, the PIN number is sent to the telecontroller 3 by pressing the buttons on the telephone 1 (on a DP line telephone 1, the commander will send a signal of the PIN number acoustically).

The telecontroller 3 checks whether the PIN sent from the telephone 1 through the telephone line 2 matches the number set by the PIN setting switch 15, which will be described later. If they match, a "confirmation tone" is emitted. (a "pin bone" is used in this embodiment) is sent to the telephone line 2. On the other hand, if the passwords do not match, a "missing message" is sent to the single-talk line 2. The operator of telephone L listens to this "answer message", inputs a new password from telephone I, and sends the correct password to telecontroller 3. If the password is entered incorrectly three times, the telecontroller 3 returns to the standby state and disconnects the telephone line 2 from the call state. This works effectively to prevent mischief or the like from manipulating electrical equipment 7.7°, 8°, etc. in the home.

When the PIN number matches and a “confirmation tone” is sent, the phone
The operator listens to this "confirmation tone" and operates the buttons on the telephone according to a predetermined procedure to control the desired electrical equipment or check its status. When the operation is completed, the telecontroller 3 goes into a standby state by turning off the telephone 1 or by sending a predetermined signal. When the telephone 1 is turned off, the telecontroller 3 enters a standby state after an arbitrary predetermined period of time.

Next, according to FIGS. 3 and 4, the above-mentioned telecontroller 3
The configuration and operation of the system will be explained.

In Fig. 3, IO is a microcomputer (hereinafter referred to as microcomputer), 11 is a home/outside switch, 12.13

9999 number can be set, I6 is an out-of-home indicator lamp, 17 is an at-home indicator lamp, 18.19 20 is a device operation indicator lamp, 21 is a connection part with telephone line 2, 22 is an N-block It is a terminal section for connecting the telephone 4, and has two types of terminals, a terminal section 22'' and a terminal section 22'', depending on the connection method with the telephone 4. That is, one terminal portion 22° of the communication connector is provided with a so-called mononular jack, and is used when the connection portion on the telephone 4 side is a so-called communication connector with a modular plug. Further, the terminal section 22'' is used when the connection section on the telephone 4 side is a screw terminal.

23 is a terminal portion to which the AC adapter 5 is connected, and is supplied with necessary power from the AC adapter 5.

24 is a terminal block for connecting the signal lines 6', 6", and 6", and is composed of three terminal blocks 24', 24", and 24"°.

Reference numeral 25 denotes a power supply unit, which generates a stable power supply for supplying the power supplied from the AC adapter 5 to the electronic circuit of the telecontroller 3. 26 is a line connection unit, 27 is an incoming call detection unit, 28 is a tone decoder that decodes the DTMF signal and converts it into a code system that is easy for the microcomputer 10 to decode, 29

It consists of a filter section that passes the required band. 31 is a signal output unit; 33 is an incoming call detection number setting switch that sets the number of incoming call detections to, for example, 3 or 7 times;
Reference numeral 34 denotes a mode changeover switch for switching the signal to a static (S) or pulsed (P) state depending on the equipment 7, 7', 8 to be controlled. 35 is a telecontrol indicator lamp indicating that a telecontrol operation has been performed;
Reference numeral 6 represents a printing section for printing out the contents of the telecontrol operation, and 37 represents a clock section.

The operation of the telecontroller 3 having the above configuration will be explained with reference to FIG. 4.

If the at-home/out-of-home selector switch 11 is set to at-home mode, the microcomputer IO reads this and enters at-home mode. Then, the at-home lamp 17 lights up, and the relay 32 becomes in a state in which its contact point is pushed down to the terminal 32a side on the incoming call detection section 27 side.

In this state, when a ringing tone is sent via the telephone line 2, this ringing tone is given to the microcomputer IO via the line connection section 26 and the incoming call detection section 27, but since it is in the at-home mode, it continues to be in a standby state. On the other hand, the telephone connected to the connection section 22 rings, and the call is received by a normal telephone. However, even in the at-home mode, if the bell rings 5 or more times a month, the microcomputer 10 switches from the standby state to the automatic response state, allowing telecontrol. This is when I go out
This is to enable telecontrol by ringing the bell for a long time even if you forget to set the go-out mode.

In the above home mode, the device switch I2.13

displayed by. That is, the operating lamps 18, 19.2
When 0 is lit, the corresponding electrical equipment 7.
7° and 8° are in the operating state or in the energized state, and when the light is off, it is in the stopped state or in the non-energized state. Equipment to be used (for example, electric locks turn on when unlocked, turn off when locked, etc.)
The meaning of turning on and turning off differs depending on the lamp.

That is, this telecontroller 3 functions as a centralized remote control within the home.

Next, when the at-home/out-of-home selector switch 11 is switched to go-out, the microcomputer 10 enters the out-of-home mode. Then, the at-home indicator lamp 17 turns off, and the out-of-home indicator lamp 16 blinks (
In this embodiment, the light is turned off for 1 second and turned on for 05 seconds, which is called slow cycle blinking). Additionally, the telecontrol operation memory in the microcomputer IO is cleared, and the telecontrol display lamp 35
is turned off.

When a call signal arrives from the telephone line 2 in this state, the microcomputer l
This will be communicated to O. When the microcomputer 10 detects the number of incoming calls determined by the incoming call detection number setting switch 33,
The relay 32 is operated and the contact is closed to the terminal 32b side.

At the same time, the out-of-office indicator lamp 1 indicates that a call is being received.
Avoid flashing 6 quickly (in this embodiment, it is called fast flashing with a period of 0.5 seconds). When the relay 32 is switched, the voice synthesis LSI 29 sends out an answering message, which is sent to the telephone line 2 via the amplifier filter 30 and the coupling transformer 26T, so that it can be heard on the other party's telephone 1.

In this state, if the telephone 1 outside the home is disconnected or the correct password is not entered within a certain period of time (in this embodiment, within 30 seconds), the relay 32 will be restored, the contact will be turned to the 32a side, and the telephone line will be connected. to open. The password is set by the password setting switch 15, and the input must be made using a DTMF signal. The signal is decoded by the tone decoder LSI 28 and sent to the microcomputer 10, where the match of the password is confirmed.

If the passwords match, a confirmation tone is sent out from the voice synthesis LSI 29, and when the confirmation tone is heard on the other party's telephone 1, actual control becomes possible.

The device control method and its response in this embodiment are as shown in Table 1 below.

Table 1 Below 1, margin - degree, when the above procedure telecontrol is performed, the microcomputer 0 will record that the telecontrol has been performed in the memory 1-,
The teleconverter display lamp 35 is turned on. The contents of the teleconference at that time are printed out on the printer section 36 together with the date and time information obtained from the clock section 37. For example, if telecontrol was performed at 10:05 a.m. on September 1, 1963, and the device with device number l was turned on,
It will be printed out as follows.

63.9.1. AMIO: 05 Kikil When the on-tele control is finished, if you press [0] [0] [6] and Punnoyuhokun, the telecontroller 3 will restore the relay 32 and open the telephone line 2, ending the operation, but if you press the button Even if you don't have one, when you put the receiver on the phone, 3
Telephone line 2 is released after 0 seconds. Even if the telephone is hung up, the teleconverter display lamp 35 remains lit and the printout remains in the printer section 36, so
After returning home from an outing, you can check whether telecontrol was performed while you were out by looking at the telecontrol indicator lamp 35, and if telecontrol was performed, you can see the detailed contents by looking at the printout. Even if the user presses the home/outside switch ll to switch to home mode when returning home, the teleconverter display lamp 35 does not turn off. This lamp 35 is turned off only when the mode is set to go out.

Further, in this embodiment, the contents of the telecontrol can be checked after returning home as described above, but it is also possible to ask the contents of the telecontrol itself through the telephone line. As the operating procedure for the button, when you press [9] [2] [#] manually, the presence or absence of telecontrol and its contents can be confirmed by the response sound shown in Table 2.

Margin Table 2 Below: Although this embodiment has a built-in printer unit, it may also be configured to provide an output port or the like to output data to an external printer, or provide a display unit such as a liquid crystal display instead of printing. A configuration in which the information is displayed is also possible. If there are multiple people to telecontrol, such as family members,
If records can be kept as described above, the problem of telecontrol congestion can be solved to some extent by mutual confirmation later. You can go further and change your PIN number each time you enter the sea (the PIN number is 4 digits long, so you can have enough for several people) and keep the PIN number in your telecontrol records, so you can control when and what kind of telecontrol. It is possible to identify not only whether the control has been carried out but also whether there has been any dripping, making confirmation work very convenient and increasing confidence.

<Effects of the Invention> As is clear from the above, according to the remote control device of the present invention, it is possible to determine whether telecontrol is performed while going out.
Alternatively, since it is possible to check when and what type of telecontrol was performed after returning home or from outside the home, confidence in the telecontrol can be increased. Furthermore, in the case where there are multiple users such as family members, and the telecontrol is likely to be crowded, the reliability of the telecontrol can be further improved by keeping records. In the unlikely event that your password is discovered and manipulated by another person, you will be able to take countermeasures such as changing your password, thereby eliminating your sense of anxiety.
