Abstract

PURPOSE:To control plural kinds of control devices with a single general controller by providing a signal procedure and data storage means where signal procedures and control data are stored in accordance with the control signal from a control signal receiving means. CONSTITUTION:When a receiving part 2 of a general remote controller 1 receives an infrared control signal, this signal is transduced to an electric signal by a photodetector 10 and is amplified by an amplifier 11. This amplified signal passes a filter 12 having the same tuning frequency as a pulse train and a detecting circuit 13 and is transduced to a digital electric signal, and this signal is analyzed by a CPU 5 to store signal procedures and control data in a signal procedure and data storage memory 4. Thus, plural kinds of device are controlled by a single general remote controller.

Description

Detailed Description of the Invention (Field of Industrial Technology Application) The present invention relates to a remote controller that remotely controls control devices such as televisions and air conditioners. It is controlled by a general-purpose controller.

(Background of the Invention) With the development of semiconductor technology such as IC, LSI, and 7-chip microcomputers, one-chip microcomputers are being incorporated into home appliances such as televisions, videos, and air conditioners, and infrared rays are becoming more and more sophisticated. The number of home appliances that can be remotely controlled wirelessly using signal media such as ultrasonic waves is increasing.

When home appliances are remote controlled in this way, a remote controller is required for each dedicated model such as a television, air conditioner, etc. For example, if there are four remote-controlled home appliances in one room at home, including a television, video, air conditioner, and lighting, there will be four remote controllers for each appliance. I had to keep several remote controllers handy.

In this way, in the past, each model had its own +! ! There was the need to find a dedicated remote controller among the various remote controllers, and the hassle of having to keep many remote controllers on hand.

Furthermore, along with the introduction of new home appliances that are already remote controlled, such as stereos and Funbakuto discs, remote control is now available! With the addition of 71 new models, the above-mentioned adverse effects are expected to continue to increase in the future.

(Objective of the Invention) The present invention was invented in view of the above circumstances, and its purpose is to control a plurality of different types of control equipment by sharing a single remote controller in order to eliminate the above-mentioned disadvantages. In particular.

(Summary of the Invention) Traditionally, the signal medium used for remote control is infrared rays, ultrasonic waves, etc., and even if different models of televisions, air conditioners, etc. use the same signal medium, such as infrared rays, A signal procedure (also called a protocol) for control signals is set for each model.
This prevents interference between different models using the same signal medium.

Currently, infrared rays are often used as a signal medium for remote control, and different control signal protocols are used for each manufacturer and model.

Therefore, the present invention receives control signals from the remote controller of each model with respect to infrared rays as a signal medium, analyzes and stores the signal procedure together with the data of the control signal, and stores the data of the stored model for the model to be controlled. It is configured to call and transmit signal procedures (protocols) and control data to control the relevant model.

A general example of an infrared control signal will now be described with reference to FIG.

When you press the control key of a dedicated remote controller (not shown) for each model that uses infrared rays (see Figure 3a), multiple address data including data, termination data, etc. are output as an infrared control signal ( The address data consists of an address bit and a data bit (as shown in Fig. 3C), and the 1-bit carrier consists of a pulse train of tens of kilohertz as shown in Fig. 3D. .

When the receiver 2 of the general-purpose remote controller 1 receives an infrared control signal as shown in FIG. It passes through a filter 12 with the same tuning frequency as the pulse train shown in FIG. It is stored in the memory 4 for use.

In this way, control signals for multiple different models such as TVs, videos, air conditioners, etc. can be sent to one general-purpose remote controller.
