Change the sign of the transmitted signal with a switch.

(3) Codes necessary for remote control are stored in a storage device whose stored contents can be changed, and a plurality of different devices are thereby remotely controlled.

On the other hand, as a method for realizing a remote control device in a compact form that allows multiple operations to be performed on a multi-functional control object, there is a method (4) in which one switch can handle multiple functions.

(Problems to be Solved by the Invention) However, the above conventional method has the following problems. That is, (1) of the above methods.

Further, in (1), there is a problem that the remote control device itself becomes large. Roughly, in the case of (3),
Since there is a limit to the number of switches that can be set, it is not possible to handle multiple functions, and it is also expensive.

It is a figure which shows the back side of the card with a built-in electric circuit shown in the figure.

In FIG. 1, a remote control device main body 1 includes a card mounting section 3 into which a plurality of electric circuit built-in cards 2a, 2b, and 2c (three in this embodiment) are mounted, and these electric circuit built-in cards 2a, 2b.

2C, a liquid crystal display panel section 5 that displays control information sent from the electric circuit built-in cards 2a, 2b, and 2C, and a battery section 6 that supplies power to the entire circuit. It is configured. Inside the card mounting section 3, as shown in FIG.
, 9c are formed, and the electric circuit built-in cards 2a, 2b, 2
C can be slidably accommodated. These card mounting grooves 9a.

When one of 9b and 9c is enlarged, as shown in FIG. 3, an electric circuit built-in card, for example 2a, is pressed and held against the inner wall of the remote control device main body 1 via a spring-like conductor 11. This spring-like conductor 11 is pasted together to form a plurality of mountain shapes using phosphor bronze plates or the like.
It is used to hold and energize a card with a built-in electric circuit, for example 2a. As shown in FIG.
3a, 13b, and 13c are arranged. Further, the back surface of a card with a built-in electric circuit, for example 2a, is formed with conductors 14 and 15 on both sides, as shown in FIG.

Next, the electric circuits of the remote control device main body 1 and the electric circuit built-in cards 2a, 2b, and 2c will be explained.

FIG. 9 is a diagram showing an example of a transmission code block.

2C is connected to the remote control device main body 1 via a power line 21. The switch 22 is one of the switches provided corresponding to a plurality of electrical circuits (circuits) that are controlled by different manufacturers. This switch 22 operates by key scanning method, and when it is pressed, the information is
It is sent to the card microprocessor 24 as control information 23 for the corresponding control object. Note that when this switch 22 is enlarged, it becomes as shown in FIG. 7. When the card microprocessor 24 receives this control information 23, it converts it into a predetermined code, which will be explained later, and sends it to the amplifier 28 as encoded control information 27. amplifier 2
8 amplifies this encoded control information 27 and then sends this amplified encoded control signal 27 through a capacitor 29.
It is superimposed on the power line 21 in the form of alternating current and sent to the remote control device main body 1. Note that the diode 30 and the capacitor 31 constitute a rectifier circuit, and the electric circuit built-in card 2
To prevent the card microprocessor 24 and the main body microprocessor 33 of the remote control device main body 1 from malfunctioning due to the AC signal as the encoded control information 27 between the remote control device main body 1 and the remote control device main body 1, the above AC signal is It is for shaping. Similarly,
A capacitor 35 provided in the remote control device main body 1. The diode 36 is also provided as a rectifier circuit for preventing malfunction. The encoded control information 27 sent to the remote control device main body 1 via the power line 21 is
The signal is amplified by an amplifier 37 through a capacitor 34 and input to the main body microprocessor 33. Note that 37 is a ground wire. The main body microprocessor 33 receives coded control information 2 pulse-shaped by a capacitor 34 and an amplifier 37.
Read 7.

Here, the encoding of the control information 23 will be explained as follows. As shown in FIG. 8, the encoding performed by the card microprocessor 24 is such that "0" and "1" are determined based on the time between the falling edges of the pulse.For example, , Invalid when this interval is less than 0.5ms, “Q” when it is between 0.5ms and 1.68m5
, "1", 3, 0 when 1.68m5~3.0ms
If it is longer than ms, it is determined to be invalid. The second transmission code follows the non-procedural transmission procedure, and as shown in Fig. 9, a start bit 41 and a stop bit 42 are added at the beginning and end of the signal, and the inside is a remote control transmission data block li3. It is composed of a display data block 44. Additionally, each block has 45.46 parity bits added to it to increase transmission reliability. When display is not required, display data block 4
4 may be omitted.

When the main body microprocessor 33 receives the encoded control information 27 encoded in this way, it reads the remote control transmission data block 43 from the signal. Then, the transistor 48 is controlled on and off. As a result, the current flowing through the infrared light emitting diode 51 connected to the battery 50 via the current limiting resistor 49 is controlled on and off, and this light emission information 52 is sent to the controlled object to perform remote control. Also, the display data block 44 is sent to the liquid crystal display 53 to be displayed, and roughly transmitted to the speaker 55 via the drive amplifier 54.
The system sounds to notify the user, thereby improving the man-machine interface.

The other electric circuit built-in cards 2b and 2C also have the same internal configuration as 2a. Therefore, by shifting the electric circuit built-in card halfway, the three electric circuit built-in cards, top, middle, and bottom, can be operated individually. This is the spring-like conductor 11 shown in FIG. This is possible as long as the conductors shown in FIG. 5 are in contact, and can be easily realized by superimposing encoded control information on the power supply line 21. Even if the manufacturer is different or the card has multiple functions, it is only necessary to change the software of the card microprocessor 24 of the card with a built-in electric circuit. In other words, if such cards with built-in electric circuits are prepared for various devices from different manufacturers, multiple devices from different manufacturers can be used.
Can be controlled with one compact remote control device without sacrificing versatility.

Note that the hardware of the remote control device main body and the card with built-in electric circuit according to the present invention can be mass-produced as a standard, and a significant cost reduction can be expected.

[Effects of the Invention] As described above, according to the remote control device of the present invention, the plurality of card-shaped electric circuits provided corresponding to the controlled objects generate control information by turning on the switch means, and encode the control information. The encoded control information is encoded and sent through the power line of the remote control device itself, and the remote control device decodes this encoded control information and transmits the control information to the controlled object using infrared rays, etc., so that different manufacturers' It has the effect of allowing multiple devices to be remotely controlled as a compact device without sacrificing its versatility.
