Abstract

PURPOSE:To surely prevent the mode changeover switch from being left unswitched by setting the mode into the presence mode automatically in loading a commander to a main body of a remote controller and setting the mode into a outing mode automatically in removing the commander from the main body 9 of the remote controller for the carrying for going out. CONSTITUTION:In loading a commander 2 to the main body 1 of the remote controller, a microcomputer in the commander 2 and a microcomputer 21 of the main body 1 give/receive a signal mutually. In this case, various signals inputted in the commander 2 are sent to the microcomputer 21 of the main body. If a signal such as answer back is not returned after the transmission, the removal of the commander 2 is by the microcomputer 21 of the main body 1. In removing the commander 2 from the main body 1 independently of the state of a mode changeover switch 7 of the main body 1 with a prescribed time of elapse, the mode is brought into the outing mode, and in loading the commander 2 to the main body 1 conversely, the mode is set to the presence mode. Thus, the mode changeover switch left unswitched is prevented surely and the remote controller is operated surely into a prescribed state.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a remote control device using a telephone line, and in particular to a device for automatically responding to a caller when the called party is absent, and for transmitting data based on the commands of the caller. The present invention relates to a remote control device that remotely controls equipment such as a video tape recorder, an air conditioner, etc. in the home of the receiving party.

BACKGROUND OF THE INVENTION 2. Description of the Related Art A remote control device, also known as a telecontrol system (telecontroller), is known to transmit various signals using a telephone line and to turn ON/OFF equipment in a receiving party's home.

This remote control device has the function of answering the caller when the called party is absent, and the control signal of the control unit based on the equipment control signal sent from the caller to the video tape recorder and air conditioner in the called party's house. It has a function to control various devices such as , and a mode switching function to switch the remote control device between at-home mode and out-of-home mode.

Problems to be Solved by the Invention With the above-mentioned remote control device, if you do not change the mode selector switch, which is the mode change function, to the out-of-home mode, the remote control device cannot be operated from outside the home. Therefore, if the user forgets to change the mode changeover switch, the remote control device cannot be reliably operated in a predetermined state.

The present invention eliminates the above-mentioned drawbacks, and its purpose is to provide a remote control device that can reliably prevent forgetting to change the mode changeover switch and can reliably perform a predetermined operation. .

Means for Solving the Problems The present invention automatically responds to the caller when the called party is absent, and controls the video tape recorder, air conditioner, etc. of the called party by controlling the control unit based on the caller's commands. The remote control device is connected to the main body 1 of a remote control device for remotely controlling a device via the handset 3 of a rotary dial telephone using a touch-tone DTM.
A commander 2 that is operated by inputting the F signal is detachably arranged, and when the commander 2 is attached to the main body 1 of the remote control device, the remote control device is automatically set to home mode, and when it is not removed, the remote control device is set to the home mode. The configuration includes means for automatically setting the mode.

Operation When the commander 2 is attached to the main body 1 of the remote control device, the home/outside mode of the remote control device is automatically set to the home mode, and the commander 2 is installed from the main body 1 of the remote control device for carrying when going out. When the remote control device is removed,
The out-of-home mode is automatically set to the out-of-home mode.

Next, the operation of the remote control device of the present invention constructed as described above will be explained with reference to the flowcharts of FIGS. 5(a) and 5(b).

The flowcharts in FIGS. 5(a) and 5(b) are for the case where the device in the home is controlled from outside in the outing mode and the ring tone is set to three times.

That is, this is a case where a caller issues a command to the remote control device via a telephone line to control the terminal equipment from outside without removing the commander 2 from the main body 1 of the remote control device.

First, this operation will be explained.

When a caller makes a call from outside, a call signal is sent from the telephone office to the remote control device via the telephone line. When the calling signal detection section 24 detects it, it sends a signal to the microcomputer 21. When the signal from the call signal detection unit 24 reaches a set number of times, the microcomputer 21 closes the connection circuit 27 to the telephone line and puts the remote control device into a talking state. Next, the voice synthesizer 30 and amplifier 31 send a message such as "I'm currently out of town" to the caller. Then, the caller sends a personal identification number (PIN code) such as ■, (2), Lil, m, etc. If it matches the set personal identification number, it sends a signal such as "ping-pon" and sends a control signal for the device. wait.

A signal in which the caller attempts to turn on equipment 1, such as a VTR (
For example, when a telephone number (formerly known as ``9'') is sent, it is input to the tone decoder 28 via the telephone line connection circuit 27 and the amplifier 29 in the same way as the password. Tone decoder 2
8 converts the signal (DTMF signal) into a binary code and sends it to the microcomputer 21. The microcomputer 21 drives the control unit 32 of the terminal device to control the device 1.
Turn on the VTR.

Next, arrange (install) the commander 2 on the main body 1 of the remote control device.
Then, the microcomputer in commander 2 and main unit 1
A microcomputer 21 performs signal control. In this case, various signals input into the commander 2 are sent to the microcomputer 21 of the main body 1, and the terminal equipment can be controlled without using a telephone line.

The above-mentioned signals are sent and received between the microcomputer 21 of main unit 1 and the microcomputer of commander 2, so if a signal such as an answerback is not returned after transmission, the commander 2 will be removed. is determined by the microcomputer 21 of the main body 1.

Another method is to attach (embed) commander 2 to main body 1.
This allows the case (outer casing) of the commander 2 to determine whether the commander 2 is present or not by turning on or off the switch inside the main body 1.

Further, the main body 1 is also provided with a mode changeover switch 7, and the mode can be changed regardless of the presence or absence of the commander 2. Regardless of the state of the mode selector switch 7 on the main body 1, if the commander 2 is not removed from the main body 1 for a certain period of time, it will be set to the out-of-home mode, and conversely, if the commander 2 is installed in the main body 1, it will be set to the at-home mode. be done.

Effects of the Invention Since the remote control device of the present invention has the above configuration,
It is possible to reliably prevent forgetting to change the mode changeover switch, and it is possible to reliably operate the remote control device in a predetermined state.
