Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention Part 1 ■Creative Field The present invention utilizes a telephone line to control the power on/off of devices at home etc. from a remote telephone. This invention relates to an improvement to a telephone controller that performs the following functions.

You can operate your home VTR from a distance to record the program you want to watch, or check the switch status of the TV, radio, room light, etc. and turn them off if you have forgotten to turn them off. It would be convenient if it could be controlled from a distance.Telephone controllers were developed with one purpose in mind to meet these requirements, and conventional telephone controllers were described in Japanese Patent Application Laid-open No. 134967/1983. I'm talking.

By the way, the conventional telephone controller mentioned above is connected to a single telephone line via a changeover switch called a disconnector, and this changeover switch must be inserted into the telephone controller side. This allows you to control the output control equipment at home etc. from a distant telephone, but if you accidentally leave the disconnector in the telephone when you go out, there is an inconvenience that you will not be able to control it from a distance. .

Therefore, an object of the present invention is to provide a useful telephone controller that solves these problems.

Hands to solve problems.

In order to achieve the above object, the telephone controller of the present invention has the following features:
An incoming call detection circuit that detects when an incoming call is received on a dial-in line assigned two office line numbers, a push-button dial signal receiver that decodes a push-button dial signal sent from the office, and this receiver. A discrimination circuit that determines whether the dial signal decoded by the station is a central office line number for a telephone set or a central office line number for output equipment control, and a calling circuit that sends a ringing signal to the telephone set when the push button dial signal from the office is for a telephone set. A signal generator, a response tone generator that emits a response tone to the station when the pushbutton dial signal from the station is for output device control, and a pushbutton dial signal sent in response to the response tone to control the output device. The device is characterized by comprising a control section that sends a signal to the output device, and a line control switch that connects and disconnects each of the devices, circuits, and dial-in lines.

Effect According to the above configuration, two office line numbers are given to one office line by the dial-in service, one number is used for the telephone, the other number is used for output device control, and this number is used by the discrimination circuit. By making this determination, it is possible to automatically distinguish whether the push-button dial signal sent through the dial-in line is for a telephone or for controlling an output device.

Therefore, commands for controlling the output device can be input to the telephone controller through the telephone line without having to switch between the telephone and the telephone controller using a changeover switch as in the prior art.

Figure 1 shows a block diagram as an embodiment of the telephone controller of the present invention. 1 is a dial-in line connected to a central office exchange (not shown), and two central office line numbers are given by the dial-in service. It is being

2 is a line control switching, 3 is an incoming call detection circuit, 4 is a push-button dial signal receiver, 5 is a control unit, 6 is a ringing signal generator, 7 is a telephone monitoring circuit, 8 is a telephone, 9 is a response sound generator, 10 is an output device control device.

The line control switch 2 is equipped with switch means r1 to r4 as shown in FIG.
7. Select and connect 9.

When an incoming call is received on the dial-in line 1, the incoming call detection circuit 3 detects this through the line control switch 2 and sends out an incoming call detection signal to the control section 5.

The push-button dial signal receiver 4 is composed of a decoder, and receives the push-button signal sent from the central office exchange through the line control switch 2 and decodes it.

The main function of the control section 5 is to output a signal for controlling the output device to the output device. The decoded signal from the receiver 4 is decoded to determine whether it is a telephone office line number or an output equipment control office line number, and the line control switch 2 is switched based on the result of the determination. In addition, signals from the incoming call detection circuit 3 and the telephone monitor circuit 7 are used to switch the line control switch 2 and to control the operations of the ringing signal generator 6 and the response tone generator 9.

The ringing signal generating device 6 is a device that generates a ringing tone for the telephone 8 when the push button dial signal is a signal for a telephone.

The telephone monitoring circuit 7 is a circuit that monitors whether the telephone 8 responds.

The response sound generating bag W9 is a circuit that generates a response sound to the central office exchange when the push button dial signal is for controlling an output device.

The output device control device 10 drives the output device (not shown) based on the control signal from the control section 5 (for example, by controlling the power source).

Next, the operation of the telephone controller having the above configuration will be explained. First, in the initial state, the switches of the line control switch 2 are in the connection state shown in FIG. 2, connecting the dial-in line 1 and the incoming call detection circuit 3. At this time, if there is an incoming call to the dial-in line 111, the incoming call detection circuit 3 detects this and sends an incoming call detection signal to the control section 5. Based on this signal, the control section 5 switches the switch means r2 of the line control switch 2 to connect the dial-in line 1 and the push-button dial signal receiver 4. This closes the DC loop of the line and sends the primary response signal to the station. Next, a push-button dial signal is sent from the station, but this signal is decoded by the push-button dial signal receiver 4 and sent to the discrimination circuit 11.The discrimination circuit determines whether it is a signal for the telephone or an output device. It is determined whether it is a control signal. At the same time, the control section 5 restores the switch means r2 of the line control switch 2 to connect the dial-in line 1 and the incoming call detection circuit 3. by this,
This means that the line's DC loop is opened and a received signal is sent to the station.

If the discrimination result of the discrimination circuit 11 is that the telephone has received an incoming call, the control unit 5 drives the ring signal generator 6 and switches the switch means r4 of the line control switch 2 to switch the ring signal generator 6 and the telephone 8. Connect. When the telephone 8 responds, the telephone monitoring device 7 sends a response signal to the control unit 5. Upon receiving this signal, the control section 5 switches the line control switch 2
The dial-in line 1 and the telephone set 8 are connected by switching the switch means r1 and r4. This closes the DC loop of the line, so a secondary response signal is sent to the station. When the telephone call ends and the telephone 8 is disconnected, the telephone monitoring circuit 7 sends a disconnection signal to the control section 5. In response to this, the control unit 5 returns the switch means of the line control switch 2 to its initial state.

On the other hand, if the determination result of the determination circuit 11 is that the call is for output device control, the control unit 5 transmits the switch means r3 of the line control switch 2 after the station becomes able to receive the secondary response signal.
to connect the dial-in line 1 and the response tone generator 9. This closes the DC loop of the line, so a secondary response signal is issued to the station. Then, after a certain period of time has elapsed, the switch means r2 of the line control switch 2 is switched to connect the dial-in line 1 and the push-button dial signal receiver 4. Therefore, next time a command for controlling the output device is sent from the dial-in line 1 in the form of a push button dial signal, it will be decoded by the receiver 4 and sent to the control section 5. The control section 5 refers to this decoded signal with its own memory, converts it into a predetermined control signal, and sends it to the output device control bag W10.

Optical tyoa button As explained above, according to the present invention, by using a dial-in line with two office line numbers, it is possible to receive calls to the telephone and to control output devices without having to provide a changeover switch. Therefore, conventional inconveniences such as forgetting to change the changeover switch or not being able to control the output device by telephone can be eliminated.
