Abstract

PURPOSE:To improve the operability by dividing a control code to control the titled device into plural levels so as to make the control items only required daily to be commanded. CONSTITUTION:A microcomputer (MC) 7 controls a relay 12 in response to a call detection signal from an incoming signal detection circuit 6 to give a frequency signal from a telephone line to a preamplifier 8 with ALC. The preamplifier 8 adjusts the level of a frequency signal. The frequency signal is identified by the DTMF receiver 9 and the identified dial number is given to the MC 7. The MC 7 outputs a control signal to the device. The item to be controlled is divided into plural levels in advance, for example, the level 1 is a control item requiring the command and the level 2 is a control item decided without any special command. When the control code based on the frequency signal from the telephone set is inputted to the controller 2 in this way, only the control of a 1st level in the plural levels is executed and in executing the control of other levels, it is executed only when the control code of the predetermined frequency signal is given from the telephone set.

The control code for controlling the equipment is divided into multiple levels, and the first level of control is executed according to the control code based on the frequency signal from the phone, and the predetermined frequency signal from the phone is executed. The system is equipped with a control means that executes the next level of control only when a control code is given.

[Function] The telecontrol device of the present invention executes control only at the first level among a plurality of levels when a control code based on a frequency signal from a telephone is input to the telecontrol device, and controls the other levels. When executing control, it is executed only when a predetermined frequency signal control code is given from the telephone, so it is sufficient to instruct only the control items that are necessary on a daily basis, and the operation for the user becomes complicated. There isn't.

[Embodiment of the Invention] FIG. 2 is a schematic diagram showing the overall configuration of an embodiment of the invention, and FIG. 3 is a schematic block diagram showing the electrical configuration of an embodiment of the invention.

First, the configuration of an embodiment of the present invention will be described with reference to FIGS. 2 and 3. First, as shown in FIG. 2, by operating a button on a public telephone 1 outside the home, a signal corresponding to the button is transmitted via a telephone line to a telecontrol device installed in the home.

The telecontrol device 2 responds to the sent signal.
It emits infrared light and controls devices such as a room air conditioner 3 and a video tape recorder 4.

The telecontrol device 2 is constructed as shown in FIG. In other words, the telephone line is connected to the telecontrol device 2.
is connected to the input end of the incoming call detection circuit 6, and a calling signal is given to the incoming call detection circuit 6 via the relay contact 5. The incoming call detection circuit 6 detects the calling signal and sends the detection signal to the microcomputer 7.
give to Microcomputer 7 controls relay 12 and switches relay contact 5 in response to the call detection signal.

When the relay contact 5 is switched, the frequency signal sent from the button via the telephone line is given to the preamplifier 8 with ALC. This preamplifier 8 with ALC adjusts the level of a frequency signal sent via a telephone line. The frequency signal whose level has been adjusted by the preamplifier 8 with ALC is given to the DTMF receiver 9 .

This DTMF receiver 9 discriminates the frequency band of the frequency signal and identifies the dial number of the operated button. The dial number identified by the DTMF receiver 9 is given to the microcomputer 7.

Every time the microcomputer 7 identifies a dial number, it generates a speech synthesis sound signal from the speech synthesis LSI10. A voice synthesized sound signal generated by the voice synthesis LSI10 is amplified by an amplifier 11 and outputted to a telephone line via a relay contact 5. Microcomputer 7 has ROM7

FIG. 1 is a flowchart for explaining the specific operation of an embodiment of the present invention.

Next, with reference to FIGS. 1 to 3, a specific operation of an embodiment of the present invention will be described.

In one embodiment of the present invention, items to be controlled are divided in advance into two or more levels. For example, level 1 is a control item that must be given an instruction, and level 2 is a control item that has been determined without giving a special instruction, or has the same content as an item that has been controlled in the past.

For example, when controlling the room air conditioner 3, level 1 is a control item that turns on the room air conditioner 3, and level 2 indicates whether to turn off the room air conditioner 3 or which room air conditioner is to be controlled. Level 3 includes air volume, set temperature, switching between cooling or heating, etc. By dividing the levels in advance in this way, level 1 is for items that are used every day, level 2 is for items that are used on special occasions, for example once a month, and level 3 is for items that are used every six months. You can set items to be used only once. This will be explained in more detail below.

When the user operates the button on the telephone 1 and inputs his or her home telephone number, a ringing signal is given to the incoming call detection circuit 6 via the telephone line. The incoming call detection circuit 6 detects the calling signal and provides the detection signal to the microcomputer 7. In response, the microcomputer 7 controls the relay 12 to switch the relay contact 5. At the same time, the microcomputer 7 generates a voice signal "I'm out now" from the voice synthesis LSI10. This audio signal is amplified by amplifier 11 and sent to the telephone line via relay contact 5. Then, the voice "I'm out now" is pronounced from the handset of telephone 1.

The user listens to the voice and then inputs the password "xxxx#" using the button. A frequency signal corresponding to this password is received from the telephone line via the relay contact 5 to the pre-printed amplifier 8 with ALC. Adjust the level of the frequency signal of the pre-amplifier 8 with ALC, and
to receiver 9. Based on the frequency signal, the DTMF receiver 9 determines the number of the operated button and provides it to the microcomputer 7.

The microcomputer 7 determines whether the number of the button matches the password stored in the ROM 71 in advance. If it matches, speech synthesis LS
110 generates a ping-ponging audio signal as a response sound. The user listens to the response sound and presses the button "20" to control the room air conditioner 3.
#" is input. The input frequency signal of the button is transmitted to the telecontrol device 2, and the microcomputer 7 inputs "At what time will it turn on" from the voice synthesis LSI 10 according to the number of the button. In response, the user inputs "1321#" from the button to turn on the room air conditioner 3 at 13:21.

Furthermore, in order to end the control of the room air conditioner 3, the user inputs "OO#" from the button. Microcomputer 7 presses “1321#” from the button.
” is input, the time is stored in a memory (not shown), and when the current time counted by software reaches the set time, a control signal is applied to one input terminal of the NAND gate 16. Open the oscillation circuit 15
A pulse signal from the driver 17 is given to the driver 17. In response, the driver 17 causes the light emitting diode 18 to emit light based on the pulse signal. When the light emitting diode 18 emits light, the room air conditioner 3 is turned on.

If there are two room air conditioners, and the room air conditioner on the first floor is normally controlled, but only on that day, two
If you want to control the room air conditioner on the floor, use the above '0'
Without inputting “0#” from the button, “20
#". Thereby, the microcomputer 7 moves to the step of executing the level 2 control item. That is, the microcomputer 7 moves to the step of executing the control item of level 2. In other words, the microcomputer 7
The user generates the voice signal “Which room is the room air conditioner in?
” and then input “00#” to end the control.
” from the button to complete the series of operations.

Note that when the user wants to set the temperature of the room air conditioner, after setting level 2, the user does not input "00#" but inputs "20#" again from the button. In response to the input of "20#" again, the microcomputer 7 moves to level 3 step and causes the speech synthesis LS 110 to generate an audio signal "How many times do you want to set it?". The user listens to the voice and inputs "20#" from the button to set 20 degrees. Then, by inputting "00#" from the button, temperature setting is completed.

[Effects of the Invention] As described above, according to the present invention, the control items for controlling equipment are divided in advance into a plurality of levels, and normally the control items are divided into multiple levels according to a control code based on a frequency signal from a telephone. Since only the first level of control is executed and the next level of control is executed only when another control code is given from the phone, you only need to give instructions for control items that are necessary on a daily basis. This greatly improves operability.
