(34 is a mode changeover switch that switches between going out mode and at-home mode, and (33) is an outside temperature sensor.

Next, the remote control operation of the above embodiment will be explained using FIG. 2 showing the operation procedure.

First, when the mode changeover switch 02 of RAS@ is set to the outing mode, a clear signal is output from the control section to FFQη of the R position fll, FFOη is cleared, and the system enters a standby state for external telephone calls.

In this state, as mentioned above, when the external telephone calls R (1), both transistors 0 and - are turned on by the output of F FO7), and the hook switches (H5l) and (H32) are turned on. It is short-circuited and becomes available for communication, and at the same time, the power switch (21b) is closed and RT E L (tl becomes operational).

Immediately after that, the initial sound is output from the output section (branch), and is sent out to the line via the amplifier circuit I24, and at the same time, the tape recorder sections are driven.

Then, on the external telephone, press the "beep" after the initial sound.
When the message is sent after waiting for the reception of the signal tone, the message output is input to the tape recorder section.
A so-called answering record is carried out.

On the other hand, after receiving the receivable signal (■), the user sends an ID signal of the ID number from the external telephone by pressing the push button on the remote control transmitter (■).This signal is detected by the push button signal receiving integrated circuit? After being identified and converted into predetermined data, it is input to the control unit of HAS4.

After recognizing the ID number, RA S @9) stops the tape recorder section (3), sets itself to device control mode, and outputs a transmission request signal (■, ■, ■) .

The output of this transmission request signal is controlled by the third
This is done by energizing the coil (24a) of the relay 4) and switching the changeover switch (24b), and then operating the output section (4), and the transmission request signal from the output section is sent through the amplifier circuit □□□. It is sent from RT E Lill to the other party's telephone.

Next, after confirming the transmission request signal on the external telephone, 0, the control device number and the control details of the control device are sent by the push button of the remote control transmitter (C1, 0).
, in the same manner as described above, this signal is identified by the integrated circuit μs in the R location and output to RAS@, and HAS@ is
It decodes this and outputs a control signal according to the control content to the applicable device, and executes the control.Furthermore, after receiving the operation confirmation signal from the applicable device, HAS@ The output unit (c) is operated to send out a transmission request signal ◎, notifying the user of the external telephone that the corresponding device has been activated and prompting the user to perform the next operation.

If the user wants to control another device, the operation procedure O9O is executed again, and the above-described control sequence is repeated.

At this time, HAS Kan is the fourth relay punishment coil (27a
) is excited to switch the selector switch (27b) to the HAS (2) side, and at the same time drives the tape recorder section (a), and the control information of the control equipment managed by HAS@.

In other words, the status of the control equipment is sequentially recorded in the tape recorder section (a).
to be recorded.

The device clears FFL17), stops the connection between the tape recorder sections, and also stops both relays and stops the operation of @.

Therefore, by clearing FF07), both transistors (+91, (3) are turned off, the operation of both relays (181° (21) is stopped, and the external telephone (
It is in standby mode for this purpose.

In this way, you can remotely control electrical equipment in your home via the telephone line, but after you return home, you can check the operating status of each equipment while you are away by playing the tape recorder section of the R station (1+). It can be confirmed.

In this case, if the status of the equipment output from RAS@ is recorded in the tape recorder unit (9) as a signal tone, it can be confirmed by decoding the reproduced signal tone with a dedicated decoder. Of course, if the HASI is equipped with a voice synthesis function, the status of the equipment can be audio recorded, and the operating status can be confirmed directly from the reproduced sound.

In addition to the above-mentioned series of operating procedures for each device in the operation steps Q to 0, HAS ( This is possible by the program processing in 29), and it is possible to turn on (or turn off) all the devices whose device numbers are consecutively transmitted, and to block the operation procedure.

In addition, devices controlled by RAS include not only devices that are simply turned on and off, such as lighting, but also devices that require temperature adjustment, time settings, and specifications, such as air conditioners and bath water heaters. It is possible to set the necessary conditions for these devices by remote control, but if you reserve (memorize) the necessary conditions in RAS4 in advance, they can be turned on/off during remote control. Control can be performed with only OFF control content, and the types of control signals can be simplified.

In this case, if the necessary conditions are not set in advance before going out, the device may not operate with only on/off control during remote control.

However, for devices that require such conditions to be set in advance, a situation in which the devices do not operate can be avoided by providing a function that allows preprogramming of control conditions for each device.

For example, after setting the temperature, like in an air conditioner.

When remotely controlling a device that requires an on switch, if standard temperature settings are pre-programmed before the user operates it, HAS ( outside temperature sensor (3) connected to
311 makes it possible to provide air conditioning for all seasons.

Furthermore, when setting the operating time of electrical equipment by remote control, if RAS@ is equipped with a timer function, it will also be possible to automatically turn off the equipment if the user does not return home from an outing.

By the way, in the above embodiment, the push button signal of the remote control transmitter was used as a control signal from an external telephone, but the invention is not limited to this, and a battery-operated melody IC can be used to send each melody as a control signal to a device to be controlled. The user's voice spoken on an external telephone may be used as a control signal.
In these cases, it is sufficient to provide a device for signal identification, such as melody identification or voice recognition, in place of the integrated circuit (c).

〔Effect of the invention〕

As described above, the remote control method of the present invention is useful when controlling various electrical devices in the home using a telephone line (in this case, by using an answering machine and a home controller, from an external telephone It is possible to directly control various devices as desired using control signals, eliminating the problems associated with using conventional electronic computers, providing users with convenience, economy, and speed. The control information, that is, the operating state, can be recorded by effectively utilizing the recording device of the answering machine without requiring any storage device, which is extremely beneficial.
