Abstract

PURPOSE:To make it possible to inform the existing location of a remote controller when it is not found by using radio waves as media for transmitting data from a main body to the remote controller and driving a buzzer in the remote controller based upon the transmitted radio waves. CONSTITUTION:When a switch 5 fixed to the main body 3 to search the remote controller 1 is depressed, a radio wave 4A is transmitted from an antenna 6 and the remote controller 1 receives the radio wave 4A by its corresponding antenna 7 and extracts relating data. When the code of the data corresponds to the switch 5, the buzzer 8 fixed on the remote controller 1 is driven. Thereby, even if the remote controller 1 can not be found, its existing location can be recognized by driving the buzzer 8 of the remote controller 1.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a cordless remote control system, and in particular, a cordless remote control system that performs two-way communication between a remote control (remote control unit) and a main body (product). [Prior Art] Fig. 2 is a diagram showing the configuration of a conventional remote control system. In Fig. 2, (1) is a remote control; ) is an infrared ray that is a medium for transmitting data output from the remote controller (1), (3) is the main unit controlled by the remote controller (1), and (4) is the data sent from the main unit (3) to the remote controller (1). The transmission medium is infrared rays.

The conventional remote control system is configured as described above, and its operation is as follows.

A code pressed with a key (not shown) on a remote controller (1) is transferred to the main body (3) using infrared rays (2) as a medium. The main body (3) performs a predetermined function according to this code.

On the other hand, the main body (3) encodes events that occur within itself and transmits them to the remote control (1) using infrared rays (4) as a medium. In accordance with this, the remote control (1) displays the contents on a predetermined light emitting diode (not shown) or sounds a buzzer (not shown).In this way, in two-way communication by the conventional remote control system, Data was sent and received between the device and the main body using infrared rays.

[Problem to be solved by the invention] In conventional remote control systems, the remote control used is small compared to the main body, and when it is hidden behind a magazine or clothes, for example, and cannot be found, it is difficult to control functions. There was a problem in that the main body could not be controlled when the main body was not equipped with a switch for this purpose.

This invention was made to solve these problems, and is a self-location notification type that allows the remote control to sound a buzzer to notify its location even when the remote control is not found. The purpose is to obtain a remote control system.

[Means for Solving the Problems] The self-location notification type remote control system according to the present invention is capable of transmitting data from the main body to the remote control using radio waves as a medium, and of causing the remote control to sound a buzzer based on the data. It is configured so that it can be done.

[Function 1] In this invention, since data from the main body to the remote control is transmitted using radio waves as a medium, the data can be received no matter where the remote control is located, and a predetermined buzzer can be sounded.

[Embodiment] FIG. 1 is a diagram showing the configuration of a self-location notification type remote control system which is an embodiment of the present invention.
>>, (2) and (3) are the same as those shown in the conventional example in FIG. radio waves,
(5) is a switch provided on the main body (3) to search for the remote control (1), (6) is a transmitting antenna provided on the main body (3) to send radio waves (4^), and (7) is a There is a receiving antenna installed on the remote control (1) to receive the radio waves (4^), and (8) a buzzer that sounds to notify the location of the beam control (1).

The operation of the remote control system configured as described above will be explained based on the drawings.

When you press the switch (5) attached to the main unit (3) to search for the remote control (1), the radio waves (4^) will be sent to the antenna (
6). In other words, certain required data is transmitted via radio waves (
4^) is sent to the remote control (1) as a medium.

The remote control (1) receives this radio wave (4^) through the corresponding antenna (7) and extracts the related data.Then, when the code of this data is the code corresponding to the switch (5), it responds accordingly. The buzzer (8) attached to the remote control (1) will sound.

In the embodiment of the invention described above, data is transmitted from the main body (3) to the remote control (1) using radio waves as a medium, and since radio waves are used for the transmission and reception system, The same effect can be achieved in the following examples. 6. Kotatsu system

・In the case of a remote control system that controls the main unit in one room through the wall in another room.

・For systems that allow you to control equipment in your room from inside your futon when you are unable to move your hands due to illness or other reasons.

[Effects of the Invention] As explained above, in this invention, radio waves are used as a medium to transmit data from the main unit to the remote control, and the remote control is configured to sound a buzzer accordingly. This has the effect of letting you know when you don't know where it is because it's hidden somewhere.

[Brief explanation of drawings]

FIG. 1 is a diagram showing a system configuration according to an embodiment of the present invention, and FIG. 2 is a diagram showing a system configuration according to a conventional example. In the figure, (1) is the remote control, (2, (4> is infrared rays, (3 is the main unit, (4^ is radio waves, (5 is the switch, (6 is the transmitting antenna, (7) is the receiving antenna, (8 is ) is a buzzer.
