Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a telecontrol system that controls the operation of a load based on control signals input via a telephone line.

(b) Conventional technology As a conventional notele control device, Japanese Patent Application Laid-open No. 60-2
No. 23763, Japanese Patent Application Laid-open No. 60-236562,
There were also those described in Japanese Patent Application Laid-Open No. 60-240263. The telecontrol devices described in these publications respond to a ringing tone from an external telephone and put the telephone line into a talking state. Thereafter, it is determined whether the passwords (such as preset numerical values) entered via the telephone line match. When the passwords match, the operation of the load is controlled based on the next input control signal.

In such telecontrol devices, the user inputs passwords and control signals in accordance with voices and sounds output from the device via an external telephone.

(c) Problems to be Solved by the Invention In the conventional telecontrol device configured as described above, ease of use for the user (family member in the house where the telecontrol device is installed) has not been emphasized. In other words, whenever this user calls home, the telecontrol device is activated and the user must enter the password. ” and other measures were taken.

However, when a third party calls, they always receive a response such as "Please enter your password," which makes no sense to the third party, so they try to call again thinking they dialed the wrong number. This was extremely unfriendly to third parties.

Furthermore, if an answering machine is installed to give priority to calls from third parties, telecontrol cannot be performed.

In view of these problems, the present invention provides a telecontrol device that prioritizes calls from third parties and also enables telecontrol.

(D) Means for Solving the Problems The present invention provides a method for responding to a telephone call from the outside, and when passwords input via the telephone line match, the load is applied based on a control signal input via the telephone line. A telecontrol device for controlling the operation of a telecontrol device, comprising: an output portion that outputs audio input from the telephone line to a recording portion that is read directly by the device; and a telecontrol device that controls the recording portion while in a talking state with an external telephone. The controller is equipped with a control unit that controls the

(*) Function The device of the present invention is equipped with an output terminal for outputting audio and a control section for controlling a recording section connected to this output terminal, so that it can be easily provided with an answering machine function.

(f) Examples Examples of the present invention will now be described based on the drawings. FIG. 1 is a main electrical circuit diagram showing an embodiment of the present invention. 1,2
3 is a telephone line, and 3 is a telephone set, which is connected to the telephone line 1.2 when the switching contact piece 4 is on the normally closed contact side. 5 is a switching contact piece, and one end of this contact piece is connected to the normally closed contact of the switching contact piece 4. 6 is an incoming call detection unit connected to the normally closed contact of the switching contact 5, and when an incoming call is detected, an H level voltage is sent to the terminal of the microcomputer 7 (microprocessor)! , output to.

Note that the incoming call detector 6 can use a normal incoming electric circuit, so the details will be omitted. 8 is a transformer, the negative side of which is connected to the normally closed contact of the switching contact piece 5. The secondary side of this transformer 8 includes an audio generating section 9 and a decoder section 1.
0 is disconnected. Note that reference numerals 11 and 12 are output terminals (output section) for outputting the audio obtained through the transformer 8.

The audio generator 9 synthesizes audio based on audio control signals from the microcomputer 7 and outputs the synthesized audio to the telephone lines 1 and 2. There are types of this voice as shown in FIG.

The decoder section 10 decodes a multi-frequency dial signal such as a telephone button input via the telephone lines 1 and 2 and the transformer 8 into numerical data.

13.14.15 is a button switch that selects 3 modes: "at home", "going out", and "answering machine", 16.17.1
Reference numeral 8 denotes a button switch for controlling the operation of No. 1 (A), No. 2 (B), and No. 3 (C), and the pressing thereof is scanned by the terminal I of the microcomputer 7, respectively. At the same time, this key scan determines whether terminals a, b, and c are open or short-circuited. Reference numeral 19 is a display unit that displays the mode and the operating status of the load.

20, 21, and 22 are relays whose energization is controlled by the microcomputer 7, and each has a switching contact piece 4. Switching contact piece 5, normally open contact piece 23
have. A relay or the like for controlling a load is connected to terminals A, B, and C as a terminal device. Note that 24 is a buffer.

25 is a recording unit consisting of a tape recorder, etc., and a microphone terminal is connected to the terminals 11 and 12, and the power is connected to the normally open contact piece 2.
I am trying to control it with 3.

Therefore, if the recording section 25 is placed in the recording state, recording can be started and stopped by controlling the opening and closing of the normally open contact piece 23.

FIG. 3 is a flowchart showing the main operations of the microcomputer 7, which are as follows. First 1! When the power source is connected and operation is started, a key scan is performed to detect whether switches 13 to 1B are pressed and whether terminals a, b, and c are shorted or open, and a RAM map as shown in Figure 4 is created. create.

In this figure, “0” represents the OFF state, and “1” represents the OFF state.
It represents the N state. Next, in FIG. 4, it is determined whether or not the mode is at home, and if the mode is at home, the relay X20 is turned off and the switching contact 4
, and connect the telephone 3 directly to the telephone line 1.2. At this time, by operating the switches 16, 17, and 18, the operation of the loads connected to the terminals A, B, and C can be controlled as a normal remote control system. For example, R shown in FIG.
If you press the switch 16 when terminal a and terminal A of the AM map are set to "1", terminal A of the RAM map will become "0", the output from terminal A will be cut off, and the load will stop.The load will stop. Then, terminal a of the RAM map becomes "0".

When switch 16 is pressed again, the load returns to the operating state.
Terminal a of the RAM map becomes "1".

When the mode is going out or answering, relay X2
0 is applied to switch the switching contact piece 4 to the normally open contact side. At this time, the relay Y21 is in a non-energized state, so the incoming call detector 6 is connected to the telephone lines 1 and 2, and the incoming call detector 6 detects the presence or absence of a ringing tone.

When a ringing tone is detected, relay Y21 is energized to switch contact piece 5. Next, the audio control signal 0.1 is sent to the audio generator 9.
is output and predetermined speech synthesis is performed. Next, determine whether the mode is answering machine or going out, and if it is answering machine, relay Z
22 is energized to cause the recording section 25 to start recording, and further outputs an audio control signal 2 to the audio generating section 9 to perform predetermined audio synthesis.

Next, it is determined whether the numerical data that can be detected by the decoder unit 10 matches a preset password. If no password is entered, it is impossible for the passwords to match, so recording continues until the end of the call is detected. That is, when the call ends, relay Y21. The relay Z22 is de-energized and a state is reached in which an initial call signal is detected. In addition, if the passwords match, relay Z22
Stop recording by cutting off power. At the same time, telecontrol is started. When the termination of the telephone call is detected, the telecontrol is terminated and a state is entered in which a ring tone is detected in the same manner as described above.

Note that the details of the telecontrol will be omitted since it may be a commonly used method.6 For example, when a multi-frequency dial signal is input via the telephone line 1.2, the decoder 10 converts the control signal into numerical data. Controls the load. Incidentally, there are types of control signals as shown in FIG. For example, when a multi-frequency dial signal of "00" is input via telephone lines 1 and 2, terminals a and b are input.

The open (OFF) and short-circuit (ON) states of C are output from the audio generator. When a signal of "11" is input, it is output from terminal A and the connected load is operated.

FIG. 6 is an electrical circuit diagram of a terminal device provided on the load side, which consists of a relay 26 and normally open contact pieces 27, 2B.

When there is an output at terminal A and the relay 26 is energized, the normally open contacts 27, 28 are closed and the load is energized.

When performing control using the telecontrol device configured as described above, first, when the mode is set to "answering machine", when a call signal is input via the telephone fil, 2, relay Y21 is activated. Turn on the electricity and switch the switching contact piece 5. Next, the relay Z22 is energized to close the normally open contact piece 23 and start recording with a tape recorder or the like. At the same time, the voice generator 9 outputs a message to the telephone lines 1 and 2 saying, "Bing Pong, I'm currently out. Please leave a message." Therefore, if the third party making the call leaves a message, this message will be recorded. Furthermore, when a party wants to perform telecontrol, he or she only needs to enter a password. When this password matches a predetermined password, recording is stopped and telecontrol mode is entered. Therefore, when a control signal consisting of a multi-frequency dial signal is input via the telephone lines 1 and 2, the operation of the loads connected to the terminals A, B, and C is controlled based on this signal.

Furthermore, if the mode is set to "going out", in response to a ring tone from the outside, the voice generating section 9 can output the message "Ping-dong, you are out now." At this time, the recording section 25 does not operate. After this message, if you want to perform telecontrol, just enter your password. If the passwords match, normal telecontrol will be performed in the same way as above.

When Kirani mode is “at home”, press switch 1
By controlling 6, 17, and 18, the load can be centrally controlled.

Incidentally, when listening to the message recorded in the recording section 25, the power plug of the recording section 25 may be connected to a normal power outlet and then played back.

As described above, in the present invention, by connecting a simple recording section such as a tape recorder to the output section, the telecontrol device can be provided with a simple answering machine function.

(G) Effects of the Invention The present invention provides a telephone that controls the operation of a load based on a control signal input via the telephone line when a telephone call from the outside is answered and the password input via the telephone line matches. The control device includes an output section that outputs audio input from the telephone line to a recording section that is read directly by the device, and a control section that controls the recording section while in a conversation state with an external telephone. Therefore, it is extremely easy to use, as it can function as an answering machine simply by connecting a recording unit such as a tape recorder.
