DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a remote controller according to the present invention will be described below in detail with reference to the drawings. In the present invention, a recognition code for each device is added to a control code indicating a control mode of an actual device, and the code information is transmitted in the form of a radio signal. Also, by setting the frequency of the radio signal to a plurality of frequencies and performing only the operation of a group of a plurality of devices for each frequency, a large number of devices are controlled with a small number of recognition codes.

That is, when a plurality of devices are operated, a recognition code for each device is added to a control code of the device so that the plurality of devices can be operated with the same control code. By doing so, it is not necessary to distinguish control codes due to differences between devices.For example, even when a number of control codes are required, such as in an air conditioner, by setting a plurality of recognition codes for one device, a small number of control codes can be used. ,
Complex control is possible. Further, since the operating devices are distinguished by the device recognition code, malfunctioning of the devices can be prevented. Further, a large number of devices can be controlled by using the device recognition code and the control code in combination.

Further, since the controlled devices are divided into several groups and the transmission frequency is changed for each group,
Devices with different frequencies do not operate, the same device recognition code and control code can be used by multiple devices, and many devices can be operated with a small number of control codes. If many device recognition codes and control codes are prepared, many devices can be controlled.

FIG. 1 is a system configuration diagram showing an embodiment of the remote controller of the present invention. In FIG. 1, devices to be controlled by remote controller 1 (devices # 1 and # 2 operated)
Control a few. The remote control device 1 includes an operation unit 11,
The control unit 12 includes a control unit 12 and a transmission unit 13. The control unit 12 selects a type of a device to be operated by an operation key of the operation unit 11 and a function to be operated, and transmits the information to the control unit 12. The control unit 12
Based on the information selected and transmitted by the operation unit 11,
A recognition code of the operated device and a control code of the operated function are generated, and group information of the operated device is also generated. The code generated by the control unit 12 is transmitted to the transmission unit 1
3 and at the same time, the group information of the device to be operated is also sent to the transmission unit 13.

The transmitting section 13 converts the code (recognition code / control code) transmitted from the control section 12 into a weak radio signal and transmits the signal to the controlled devices 2 and 3 via the antenna. At this time, the frequency of the weak radio wave is determined by the device group information transmitted from the control unit 12.

On the other hand, the controlled devices 2 and 3 receive the radio signals transmitted from the transmission unit 13 of the remote control device 1 and receive the reception codes 21 and 3 for restoring the recognition code and the control code information.
1 includes control units 22 and 32 for receiving the restored recognition code and control code information and controlling the devices.

As shown in FIG. 2, the receiving unit 21 filters out only a radio signal of a frequency assigned to its own device from a weak radio wave received via an antenna.
1 and a code restoring unit 212 for restoring recognition code and control code information from the filter output signal. The receiving unit 31 has a similar configuration.

As shown in FIG. 3, the control unit 22 checks the device based on the recognition code included in the code transmitted from the receiving unit 21 and determines whether the device is to be operated. The control device confirmation unit 221 is provided. At this time,
If it is determined that the device is not an operated device, the control code is ignored. If the device is operated, the control code is sent to the internal device, and the corresponding operation is performed.
The control unit 32 has a similar configuration.

In the example shown in FIG. 1, since the device (# 2) 3 is operated by the remote control device 1, even if the device 2 receives a radio wave, no control or operation is performed on the device 2 side, and the device 3 is not operated.
Only when the device receives the radio wave, the control operation of the device 3 is performed.
