Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a transmitter that wirelessly transmits a remote control signal, and a relay control that controls a plurality of controlled devices by wire by receiving the remote control signal from this transmitter. The present invention relates to a remote control device equipped with a device.

[Conventional technology]

BACKGROUND ART Conventionally, in the field of audio and video equipment (hereinafter referred to as AV equipment), each equipment is controlled remotely (hereinafter referred to as remote control) by operating a transmitter at hand.

This remote control control is performed by wireless transmission and reception using infrared rays or the like as a medium.

Furthermore, in order to prevent malfunctions, a dedicated transmitter for each device is used for the wireless transmission and reception, and each dedicated transmitter transmits a control signal with a unique control code for each device.

By the way, when using multiple AV devices in combination,
In the control using the dedicated transmitter, for example, when the playback image of a video tape recorder (hereinafter referred to as VTR) is monitored on a television receiver (hereinafter referred to as TV), input mode switching of the TV, playback control in (1), etc. In order to do this, VT
It is necessary to operate the R, TV transmitter, and the operability is extremely poor.

Therefore, a single transmitter can be used to perform complex control of multiple controlled devices, and in the case of monitoring the playback image, the necessary control of the VTR and TV can be automatically performed using a single control device called the playback control of the VTR. It is desirable to do so.

When using multiple controlled devices in combination,
Conventionally, an IJ control device as shown in FIG. 4, 1p, is used which controls the operation of each controlled device by wired control.

In the same figure, (1a) is a transmitter, (2a is a transmitter (
a relay controller that receives a wireless remote control signal (3);
a) *(4a) and (5a) are TVs as controlled devices;
Component type audio equipment (hereinafter referred to as component), V
TR, and is connected to the relay controller (2a) via the control line (6a).
connected to the moon.

Then, the relay controller (2a) controls the TV (3a) and the component (4a) according to the control content of the received remote control signal.
).

Performs wired control of single and combined bidirectional communication of the VTR (5a).

For example, when playing back a VTR (5a), "VTR playback" is sent from the transmitter (1a) based on the operation of one controller for VTR playback.
When a remote control signal for composite control is transmitted, the relay controller (2a) executes composite control for "1 VTR playback" based on reception of this remote control signal.

At this time, the relay controller (2a) sends a remote control signal for switching the input of "1 external input" to the TV (3a) via the control line (6a), and also sends a remote control signal for switching the input of "1 external input" to the VTR (5a). Send remote control signal.

Then, the input mode of the TV (3a) switches to external input, and the VTR (5a) starts playing.
The reproduced signal in (5a) is transmitted to T via a signal line (not shown).
V (3a), and the reproduced image of yTR (5a) is displayed on the TV.
(3a) Monitored.

In addition, when performing a single control operation such as turning on/off the power of the VTR (5a), the relay controller (
2a) also sends a power on/or remote control signal to only the VTR (5a).

By the way, in the case of the remote control device shown in FIG. 4, the transmitter (
1a) transmits only the remote control signal of the relay controller (2a), TV (3a), and near amplifier (4a).
, the VTR (5a) must be connected to the relay controller (2a), which is inconvenient, such as limiting the degree of freedom in installation.

On the other hand, Japanese Patent Application Laid-open No. 63-24790 (HO4Q 91
In 00), each controlled device is a dual control type device whose operation is controlled by wired control and wireless control, and the remote control of each controlled device is wired control using a relay controller.

A remote control device is described that can perform wireless control using each dedicated transmitter.

During wired control, this remote control device receives a relay control remote control signal wirelessly transmitted from a common transmitter with a relay receiver serving as a relay controller, and this receiver transmits the received code signal to the controlled device. It converts the code into a remote control signal for each device and sends it to each controlled device by wire.

Furthermore, during wireless control, wireless remote control signals from each dedicated transmitter are received and processed by each controlled device.

In addition, during wired control, when each controlled device receives and processes a remote control signal from the common transmitter, interference of remote control signals occurs. It is also described that each controlled device is prohibited from accepting wireless control during wired control.

In the case of the remote control device described in the above-mentioned publication, the operation of each controlled device can be controlled by either wired control or wireless control, but when only a common transmitter is used, there is a disadvantage that only wired control can be performed.

Furthermore, since the relay receiver only converts the code of the received remote control signal, there is also the disadvantage that the above-mentioned combined control cannot be performed by a single controller.

Therefore, by combining a relay controller that performs single and combined wired control with one transmitter, this transmitter can perform wired control and wireless control of controlled devices of both control types. It is possible to eliminate this problem.

In this case, the remote control device is configured as shown in FIG. 5, for example.

In the same figure, (1b) is a transmitter, (2b) is a relay controller corresponding to the relay controller (2a) in FIG. 4, (3b),
(4b).

(5b) is a TV, a component, and a VTR as controlled devices, and at least the VTR (5b) is formed of a surface control type device, and the TV (3b) and component (4b) are connected via a control line (6b). and is connected to the relay controller (2b).

The transmitter (lb) transmits remote control signals for relay control and surface control type equipment 9 according to settings at the time of manufacture, learning and memory, etc.
For example, it stores and holds remote control signals for direct control of the VTR (5b).

Further, when a control operation is performed on a surface-controlled device such as playback on a VTR (5b), a remote control signal for direct control is wirelessly transmitted together with a remote control signal for relay control.

For example, when playing a VTR (5b), the transmitter (1b)
) is the ``VT'R playback control signal for relay control,
A remote control signal for direct control consisting of a unique control code of the VTR (5b) for one playback is continuously transmitted.

At this time, based on the reception of the remote control signal for relay control, the relay controller (2b) sends a remote control signal for input switching of the east external input to the TV (3b), and based on this remote control signal, the The input mode switches to external input.

In addition, ■1 (5) is not connected to the relay controller (2b).
In b), the remote control signal for direct control is received and processed. In this case, even if the VTR (5b) is not connected to the relay controller [2b], multiple remote control signals can be controlled by one controller for VTR playback. will be held.

[Problem to be solved by the invention]

In the case of the remote control device shown in Fig. %5, the following problems occur when a surface control type device is connected to the relay controller (2b).

That is, when the VTR (5b) is connected to the relay controller (2b) as shown in FIG. The remote control signals from (2b) are sequentially input.

Particularly in the case of a remote control signal for a toggle operation such as power on/off, the VTR (5b) is controlled twice by both remote control signals input in sequence and returns to the state before the control.

For example, when the VTR (5b) is powered off, the transmitter (1b)
) sends a remote control signal for VTRVTR power on/off control and a remote control signal for direct control of power on/off I.

Then, by receiving and processing remote control signals for direct control,
When the VTR (5b) is controlled from power on to power off, the relay controller (2b) then transmits 1 to the VTR (5b).
A remote control signal for "power on/off" is sent, and this remote control signal turns the VTR (5b) back on.

Therefore, erroneous control of the toggle operation of the surface-controlled controlled device occurs.

In addition, in order to solve the above problem, VTR (5b
) etc., it is conceivable to provide the selection gate described in the above publication for each surface control type controlled device, but in this case, a selection gate must be provided for each controlled device, which poses the problem of high cost. be.

An object of the present invention is to provide a remote control device that prevents erroneous control of the toggle operation with an inexpensive configuration.

[Means to solve the problem]

In order to achieve the above object, the remote control device of the present invention has the following features:
When controlling a surface control type controlled device, a transmitter that wirelessly transmits a remote control signal for direct control as well as a relay control remote control signal is used to determine whether direct control is possible or not for each surface control type controlled device. a transmission condition setting section to be set, and a transmission control section that prohibits transmission of the direct control remote control i-control signal based on the setting section's prohibition setting when controlling the surface control type controlled device. and.

[Effect]

In the case of the remote control device of the present invention configured as described above,
When controlling a surface-controlled controlled device, the transmission control section selectively prohibits the transmission of remote control signals for direct control based on the operational settings of the transmission condition setting device.

Therefore, if the controlled device of both control types connected to the relay controller is set to disable direct control, the transmission of remote control signals for direct control is prohibited, and the controlled device of both control types The operation is controlled only by wired control of the relay controller,
Erroneous control of toggle operation is prevented.

Furthermore, in order to prevent erroneous control by controlling the transmission of the transmitter, there is no need to provide a selection gate between wired control and wireless control, etc., as described in the above publication, for each controlled device of both control types. The configuration forms a device.

7) is a transmission condition setting section, and when the controlled profit and loss of both control types is TV, VTR, and component, TV is set as shown in Figure 2.
It consists of tip switches (7a), (7b), and (7c) for enabling or disabling direct control of the , VTR, and component.

(8) is a relay control memory in which data of various remote control signals for relay control is written; (9) is a direct control memory in which data of various remote control signals for direct control is written; 1to) 1 is a transmission control unit consisting of a microcomputer, and 1 is a transmission output circuit that wirelessly transmits remote control signals.

The transmitter (IC) is formed by adding a transmission condition setting section (7) to the transmitter (1b) and changing the transmission control section of the transmitter (1b) to a transmission control section (IO). .

In addition, the remote control signal for relay control of the transmitter (IC) is
It is received by the same relay controller as the relay controller (2b) in FIGS. 5 and 6.

Furthermore, each switch (7a) of the transmission condition setting section (7)
(7C) is set by a switching operation based on whether or not a dual control type TV, VTR, or component is connected to the relay controller.

In other words, when not connected to a relay controller, each switch (7a) to (7C) is held in one continuous state corresponding to direct control, because no inconvenience occurs even if a remote control signal for direct control is transmitted. Ru.

In addition, when connected to a relay controller, each switch (7a) to
(7C) is switched to 1 alone, which corresponds to not being directly controllable.

FIG. 2 shows the settings of the switches (7a) to (7C) when only the VTR is connected to the relay controller.

Next, the operation of the transmitter (IC) will be explained.

The key input circuit (6) is activated by key operation on the transmitter (IC).
When a control operation signal for one of the dual-control type TV, V, TR, and component equipment is input to the key input circuit (
6), the transmission control unit (10
) executes the transmission control shown in FIG.

In this case, the data of the remote control signal for relay control of ■1 playback is first read from the relay control memory (8), and the remote control signal for relay control based on this data is sent to the transmission output circuit (wireless transmission from the river). .

Next, based on the confirmation of the transmission target device, the transmission condition setting section (
The settings of the switches (7a) to (7C) of the transmission target device 7) are detected.

If the switch (7b) of the VTR is switched to "whisper continuous" and is set to enable direct control, a remote control signal for direct side control is wirelessly transmitted from the transmission output circuit (l+).

On the other hand, if the switch (7b) of the VTR is set to "only" and is set to disable direct control, transmission of remote control signals for direct control is prohibited, and the transmitter (IC) transmits remote control signals for relay control. The process ends after sending only the

Therefore, when the VTR is connected to a relay controller, by switching the switch (7b) to 1 alone,
Based on the remote control signal for relay control of the transmitter (IC), V
The operation of the TR is controlled only by wired control of the relay controller, thereby preventing erroneous control when controlling toggle operations such as power on/off.

Then, the switches (7a) to ( of the transmission condition setting section (6)
7C), the transmission of the transmitter (LC) is controlled to prevent erroneous control, so there is no need to provide the controlled device with the selection gate or the like described in the above-mentioned publication.

Note that the number of switches in the transmission condition setting section (6), etc. are not limited to those in the embodiment.

Moreover, it can be applied to remote control control of not only AV equipment but also various equipment.

〔Effect of the invention〕

Since the present invention is configured as described above, it achieves the effects described below.
