Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a remote control device suitable for use in remotely controlling electronic devices, electric door locks, electric garage locks, and the like.

[Summary of the invention]

The present invention decodes a format designation code signal from the commander, generates a series of operation signals according to the specified format, and sequentially controls the remotely controlled unit using the series of operation signals. This allows multiple electronic devices to be controlled continuously by simply pressing the button once.

[Conventional technology]

In general, remote control devices for remotely controlling various electronic devices have been proposed (for example, Japanese Patent Application Laid-Open No. 123382/1982).
It has also been proposed to use such a remote control device to remotely control an electronic door lock, a garage electric lock, a gate light, etc.

[Problems to be Solved by the Invention] By the way, in the case of a conventional remote control device, when the commander specifies, for example, to turn on the power, in the case of a television receiver, only the receiver, V 'I' l (then V TI (only) , it was only effective for a single device. This is because the remote control signal codes are different even when the power is turned on at the same time. Therefore,
For example, video camera, TV Gittan i11. V'rR
When a system was set up and the entire system was to be operated, it was impossible to turn on each device with a single commander.

Furthermore, in the case of remote control devices made by different manufacturers, even if the same television receiver is pressed, the commander's power-on button usually does not work.

Another option is to put a program that performs a series of actions into the commander of a remote control device, and then press a specific button to send out a signal containing that program. This was inconvenient as it was necessary to point the commander at the light receiving section.

This invention was developed in view of these points, and allows each device to be turned on continuously using a single commander with simple operations, and can also be used with remote control devices from different manufacturers. A remote control device is provided.

[Means for solving problems]

The remote control device according to the present invention includes a commander (1) that generates a format designation code signal, and a transmitter (2) that decodes the format designation code signal from the commander and issues a series of operation signals according to the designated format. ) and remotely controlled units (5 to 10) that are sequentially controlled by a series of operation signals from the transmitting means.

[Effect]

A specific format rf1 code signal is generated from the commander +1). This format designation code signal is one of a series of formats stored in advance in the transmitting means (2).
When the two codes match, one of a series of formats is specified. Then, a series of operation signals are sent out from the transmission means according to the specified format, and these are transmitted to each of the speed control units (5 to 10).
) is decoded by the decoder (5a to 10a), and if it matches the self-backent format, the remote fi control unit is controlled. As a result, a plurality of remote control units 1) dark blue 11% can be controlled continuously with occasional operations.

(Example) Hereinafter, an example of the present invention will be described in detail based on FIGS. 1 to 5.

FIG. 1 shows the line configuration of this embodiment. In the figure, (11 is a commander of a remote control device, and this commander (1) is a keyboard part (la), a remote control transmitter IC (lb), as is well known, ), infrared, line-emitting diode (lc
), an operation display diode (ld), and a drive transistor (1e), and by operating one of the function keys on the keyboard section (la), a format specification code signal is sent from the remote control transmitting IC (lb). This code signal is amplified by a drive transistor (1e) to a signal size necessary for transmission, and then an infrared light emitting diode (1c) modulates an infrared carrier wave, for example, 40 kHz, and transmits it. In this case, the format designation code signal is predetermined and stored in advance in the memory of the remote control transmitting IC (2b). Note that this format designation code signal is simply a code signal consisting of a number representing the number of rows of the format.

Further, (2) is a transmitter that receives a format designation code signal and generates a series of operation signals according to the designated format. ). The transmitting section (2) consists of an infrared receiving block (2a) and a phycrocomputer (hereinafter referred to as a microcomputer) (2b) that constitutes a decoder, and a predetermined format designation code signal is sent to the microcomputer (2b). It has a stored data table, and compares the format designation code signal received by the infrared receiving block (2a) with the format designation code signal stored in the data table, and when they match, designates the format corresponding to the code signal. and sends a series of operation signals to the data bus (4). For this purpose, the microcomputer (2b) further stores a predetermined format.

The code format that forms the basis of a predetermined format for generating a series of operating signals is shown in FIG. It consists of a guide pulse as a discrimination signal, a 7-bit data code following this guide pulse, and a 5-bit category code following this data code. In this case, this data code is assigned to the control of the required operating function within the determined category,
It is possible to control 128 functions, and this category code is assigned to each category of the remote control device, such as an electric lock, and up to 32 categories can be assigned.

The microcomputer (2b) continuously generates a series of operation signals for each controlled section in accordance with the packet format shown in FIG. 4, which is comprised of the code format shown in FIG.

That is, in Figure 4, the first three frames represent functional addresses, specifically those shown in the left column of Figure 5, and the next three frames represent device addresses, specifically. The order shown in the middle column of Fig. 5 is given to the items in the left column of Fig. 5, and the last three frames represent operations, specifically the operations shown in the right column of Fig. 5. The items in the left column of the j$5 diagram are controlled so as to perform the following. Note that the numbers on the left side of each column in FIG. 5 represent each code number.

Therefore, for example, the first (#1) light is turned on (ON).
), at point A, the data corresponding to the light code number 84 is entered into the data code shown in Figure 3, and the security code data is entered into the category code, and this is repeated for 3 frames. Data corresponding to #l code number 97 is entered in the data code, security code data is entered in the category code,
This is repeated for 3 frames, and at C, data corresponding to the ON code number 57 is entered in the data code of the m3 diagram.
Sequiality code data is entered into the category code, and this is repeated for 3 frames. Now about the light
Transmission of the packet signal ends. Then, to transmit a series of operation signals, one packet related to this light is followed by one packet related to another remotely controlled unit, such as the door (electric lock), and then the garage (electric lock) is transmitted.
1 packets related to the above are transmitted. Therefore, the data table of the microcomputer (2b) stores a series of combinations of each remote-controlled unit in a predetermined format, corresponding to each key of the keyboard unit (1a) of the commander (1). For example, a format arranged to work in the order of door camera and monitor VTR is stored in correspondence with the first button of the keyboard part (la), and the second button is stored.
It is as if a format is stored in which the buttons are arranged to work in the order of light, garage, camera, and monitor. Of course, this order may be arbitrary as to what comes first.

In this way, a series of operation signals sent from the microcomputer (2b) of the transmitter (2) to the data bus (4) are sent to a remotely controlled unit connected to the data bus (4), such as an electric door lock (5). , lights (6), garage electric lock (7), video camera (8), V i"R ('l) and monitor (1)
0) D is supplied. Door electric lock (5) ~ Monitor (10)
) each have decoders (5a) to (10a), and each of these decoders has a data table that stores its own packet format, and selects a series of transmitted operation signals that match its own packet format. Do it too
If there is □, it will start. Video camera 18)
The imaged video signal from V i' R (9) and the monitor (
10).

Now, when you press, for example, the first button on the keyboard section (1a) of the commander (1), the corresponding format designation code signal is read out from the remote control transmitter tc (lb).
It is sent out via an infrared light emitting diode (1c).

This sent format specification code signal is sent to the transmitter (
2) is received by the infrared light receiving block (2a) and compared with the format designation code signal recorded in the microcomputer (2b), and if they match, the format number is specified. In this case, since the first key was pressed on the keyboard section (1a), the door camera-monitor VTR
The number of formats arranged to work in the order of is specified.

``Then, the microcomputer (2b) outputs a series of operation signals to the data bus (4) in accordance with the packet format shown in FIG. 4 so as to operate in the order of the door camera and the monitor VTR.

This series of operating signals is transmitted from the decoder (5a) of the electric door lock (5) to all the decoders (10a) of the monitor (10) via the data bus (4). Each decoder determines whether or not its own packet format exists in a series of operation signals, and if so, controls the main body. If the code contains data corresponding to the code number section, data code B contains data corresponding to code number m, and data code C contains data corresponding to the code number section, the electric lock of the first door ( 5) (1st
(Only the first one is shown in the figure) is opened,
In the next packet, the data code of A corresponds to the code number A, the data code of B corresponds to the code number part, and the data code of C corresponds to the code number 57 (,
If there is a person in the data code 6, the first video camera (8) (only the first one is shown in Figure 1) is turned on, and the data code of A in the next packet is turned on. If there is data corresponding to code number 8'7, data corresponding to code number 97 in the data code of B, and data corresponding to code number 57 in the data code of C, then
The first monitor (10) (only the first one is shown in Figure 1) is turned on, and the data code of A in the last packet contains data corresponding to code number 88, and If the data code contains data corresponding to code number 97, and the C data code contains data corresponding to code number 57, then the first VTR 19) (Figure 1 only shows the first one) is turned on.

As described above, in this embodiment, the commander (+1) only sends out a simple format designation code signal that is short in time, and the transmitter (2) that receives this signal generates a - series of operation signals to continuously The remote control unit can be controlled remotely and the operation is extremely simple.

Note that if the format differs depending on the manufacturer, the format may be changed using the microcomputer (2a).
