Abstract

PURPOSE:To allow a single commander to cope with plural equipments to be controlled by providing a means selecting a specific custom code through a key operation and a means generating a control signal corresponding to the selection means. CONSTITUTION:According to the operational result of a custom code switching input key 15, that is, the selected custom code, any one of control signal generation means 21-23 is validated through a controlled device switching circuit 20, and a control signal generated in accordance with the operational result of control input keys 11-14 is transmitted to a transmission signal generation means 25. According to the operational result of the custom code switching input key 15, the custom code is transmitted to the transmission signal generation means 25 through a custom code selection means 26. The transmission signal generation means 25 combines the custom code with the control signal, and transmits them to the device to be controlled through a transmission part 17 without a wire.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a wireless commander for controlling equipment wirelessly.

(Technical background of the invention and its problems) Air conditioners (hereinafter referred to as air conditioners), television receivers (hereinafter referred to as televisions), audio equipment (hereinafter referred to as
(called audio) and more! ! Wireless commanders are often used to remotely control a single device. Many of these commanders send control signals to controlled equipment.
Control signal information is loaded onto carrier waves such as radio waves, light, or infrared rays and transmitted through space. When transmitting using such a space, the transmitted signal is freely transmitted to devices other than those intended for control by the operator, and even devices not intended by the operator may operate ( In order to eliminate such inconveniences, conventionally, as shown in FIG.
A custom code 52 specific to the controlled object in the transmission signal containing 1
is built in, and the controlled (11i device side is configured to accept the signal sent from the commander only if the custom code included in the signal matches its own code. If the custom code in the signal does not match the own code, the signal will be ignored from now on.This will prevent the operator from controlling only the intended device and affecting other devices. is prevented.

However, when following the above method, a device-specific commander is required for each of the 18N devices to be controlled, and as the number of controlled devices increases, the commanders become diverse and gradually become complicated.

[Purpose of the invention]

The present invention has been made in consideration of the above circumstances, and aims to provide a wireless commander that can avoid complexity on the operator's side even if the number of devices to be controlled increases. be.

(Summary of the Invention) The wireless commander of the present invention includes a plurality of custom codes and control signal generation means corresponding to each custom code, and selects a specific custom code by key operation and generates a control signal corresponding to the custom code. By selecting a method, a single commander can handle a plurality of controlled 2I1 devices.

(Embodiment of the Invention) FIG. 2 shows an example of the appearance of a wireless commander constructed according to the present invention. The commander 10 includes a plurality of control input keys 11, 12, 13, 14, a custom code switching key 15, an operation display section 16 consisting of, for example, a liquid crystal display, and an infrared transmission section 17, for example. There is.

The function of the wire 1 commander 10 will be explained in detail below with reference to FIG.

In the embodiment shown in FIG. 1 and below, an air conditioner, a television, and an audio device are exemplified as the controlled aIIIXII devices. Means 23 are provided. These control signal generating means 21 to 23 are controlled according to the custom code selected as a result of the operation of the custom code switching input key 15.
Only one of them is enabled through the device switching circuit 20, and a control signal generated according to the operation result of the control input keys 11 to 14 is sent to the transmission signal generation means 25. On the other hand, the custom code is sent to the transmission signal generating means 25 via the custom code selecting means 26 in accordance with the operation result of the custom code switching input key 15. The transmission signal generating means 25 combines this custom code and the above-mentioned control signal in the form shown in FIG.
7Response to the controlled □ device and send. On the controlled device side, the signal transmitted wirelessly from the transmitter 17 is received, and the custom code included in the signal is identified to determine whether it matches the own custom code. If the signal matches, subsequent control is performed. Accepts the signal and ignores subsequent control signals if they do not match. Note that the operation result of the custom code switching person key 15, that is, the selected custom code is converted to the name of the controlled device, for example, "air conditioner" or "audio" on the operation display section 16 via the display switching means 26. displayed in the form shown.

3 and 4 do not show an example of the display contents of the operation display section 16 and the functional assignment of the control input keys 11 to 14.

Figure 3 shows the case when it is used for air conditioner operation, and Figure 4 shows the case when it is used for audio operation.
It shows each state. As shown in Figure 3, when used for operating the air conditioner, the input key 11 is used to turn on/off the power.
For off, input key 12 is for heating/cooling switching, input key
Reference numeral 13 is used to adjust the set temperature in one stomach direction, and input key 14 is used to adjust the set temperature in the downward direction.The operation display section 16 displays the functions of each input key 11 to 14, the set temperature, etc. It is displayed together with "Air conditioner". When used for audio operation as shown in Fig. 4, input key 11 is for turning on/off the power, input key 12 is for switching between phone player/radio, input key 13 is for maximizing the sound, The input keys 14 are used to decrease the volume, and the operation display section 16 displays the function of each input key and numerical values indicating the approximate set volume, along with a display of 1 audio.

The displayed contents and layout of the operation display section 16 shown in the drawings are merely examples, and can be modified as necessary.

〔Effect of the invention〕

As described above, according to the present invention, a plurality of controlled devices can be selectively controlled by a common commander, and even if the number of devices to be controlled increases, they can be controlled by a common commander. Therefore, even if there are a plurality of controlled iIl separate devices, it is possible to avoid complication for the operator.
