Abstract

PURPOSE:To control all controllable equipments with a single controller by providing a storage means which reads a signal format or the contents of the modulated frequency, an operating part, and a display part. CONSTITUTION:A data input part 21 inputs various data on the modulation systems, the frequencies, the signal formats, etc., which are used for control of various controlled equipments. These input data are stored in a data storage part 22 through a control part 23. Then a user selects a controlled equipment through a key input part 20 while looking at a display part 24 and then inputs a command. Thus the part 23 reads the data on the modulation system, etc., of the selected equipment out of the part 22 and controls an infrared ray output part 25 for output of a proper infrared ray. Meanwhile an infrared ray output control part 26 sets the oscillation frequency, etc., to an infrared ray driving oscillation circuit 27 based on the data read out of the part 22. Therefore the controlled equipments can be selected in number accordant with the storage capacity of a transmitter.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control system using a remote control device and a transmitter for remotely controlling the remote control device.

[0002]

2. Description of the Related Art As a conventional remote control system, there are a controller for controlling the input of channels, volume, etc. of a television, an air conditioner, a stereo, etc., and a television, an air conditioner, a stereo, etc.

This system has a common feature that infrared rays are used as a transmission means for control signals, but its modulation method, modulation frequency, signal format, etc. differ depending on each manufacturer and model, and standardization is uniform. Not done.

FIG. 1 shows an example of using the conventional system. 1
Is a TV, 2 is a controller of 1, 3 is a VTR, 4 is 3
5 is an air conditioner, 6 is a controller 5, 6 is a video disk, 8 is a controller 7, 9 is a stereo, and 10 is a controller 9.

[0005]

As shown in FIG. 1, it is very inconvenient to use because the controller is required for each device and the operation method is different. There wasn't.

In order to solve the above problems, it is an object of the present invention to realize a system in which all the controllable devices can be controlled by one controller.

2 (1) is a block diagram of an embodiment of the present invention, in which 20 is a key input section, 22 is a data storage section, 23 is a control section, 24 is a display section, and 25 is an infrared output section. is there. In order to operate these, first, data such as the modulation method, frequency, and signal format used for controlling each of the controlled devices is input from the data input unit 21, and stored in the data storage unit 22 by the control unit 23. To be done.
Next, the user looks at the display unit 24 and looks at the key input unit 20.
When the device to be controlled is selected and a command is input, the control unit 23 reads the data such as the modulation method for the device stored in the data storage unit 22 and controls the infrared output unit (infrared output means) 25. Then, an appropriate infrared ray is output.

FIG. 2B is a configuration diagram of the infrared output control section included in the control section 23 and the infrared output section 25. 26
Is an infrared output control unit, 27 is an infrared drive oscillation circuit, 2
Reference numeral 8 is a modulator, and 29 is an infrared output element and a drive circuit. The infrared output control unit 26 sets the oscillation frequency for the infrared driving oscillation circuit 27 based on the data from the data storage unit 22, and outputs the signal of the frequency designated by the infrared driving oscillation circuit 27. Further, the infrared output control unit 26 encodes the command input from the key input unit 20 with the data from the data storage unit 22, and the modulation unit 2
The code and modulation method are set to 8. The modulator 28 modulates the signal from the infrared driving oscillation circuit 27 and outputs the infrared signal from the infrared output element 29 including the drive circuit.

FIG. 3 (1) shows an embodiment in which a ROM (Read Only Memory) cartridge is used in the present invention. Reference numeral 30 is a ROM cartridge in which command data of a controlled device is recorded, and 31 is. ROM
It is a means for reading data from the cartridge 30. In this embodiment, a ROM in which data is recorded in advance
To use the cartridge, the user selects the device,
You just have to enter the command.

FIG. 3B shows a remote control device when a ROM cartridge is used. 40 is a display unit, 41 is an input switch, 42 is a ROM cartridge, and 43 is an infrared output unit. In the ROM cartridge 42, data of infrared signals corresponding to the controlled device is recorded, and a necessary cartridge is set in advance.

In operation, when a controlled device is selected and input by the input switch 41, a command for that device is displayed on the display unit 40, so the infrared output unit 43
, And then inputs a command from the command input means 41 which is an input switch. The size of the remote control device of this embodiment is about the same as the size of one conventional controller, and thus is very easy to use.

FIG. 4 shows an embodiment in which the remote control device according to the present invention is used as a wristwatch, and has a timepiece function and a controller function. Reference numeral 50 is a display unit, 51 is a switch unit, 52 is an infrared output unit, and 53 is an R0M cartridge unit.

Similar to the embodiment shown in FIG. 3B, the necessary ROM cartridges for the controlled devices are connected (three in the figure), and the switch section is displayed according to the display on the display section 50. By inputting a command from 51, infrared rays are output from the infrared output section 52, and the controlled device is controlled.
