Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a stereo system with a remote control device for remote control.

In particular, it is equipped with a bus line to collect information from each device, and the transmitter/receiver section allows the status of the entire system to be known.
Regarding two-way remote control technology.

Background of the Invention Remote controls are currently used in a variety of devices. The most common remote control is one that unilaterally sends commands to operate the device. System remote controls have also been proposed that operate multiple devices such as stereo systems. This method uses a remote control that can send commands for multiple devices, each with a receiving section (see Figure 7). Only one device has a receiving section, and that device converts it into an electrical signal.
There is a method of transmitting a command signal to each device using wiring that connects each device and operating the device (see FIG. 8).

Recently, as shown in Figure 9, a transmitter and a receiver are installed in each device and remote control, so that the remote control transmits a command signal, the device receives the command signal, operates, and the device transmits its operating status data. However, a so-called two-way remote controller has been proposed in which the remote controller receives operating state data and displays the operation results on the remote controller.

It has been proposed that devices, systems, etc. become more integrated into daily life than the problems that inventions aim to solve, in which the hardware is stored away as much as possible, installed out of sight, and only the control unit is placed at hand. In this case, it is necessary to know the status of the device from the control unit. Conventionally proposed two-way remote controllers are implemented for one device. If this were to be developed and implemented with multiple devices, it would be necessary to install a transmitter/receiver in each device, which would increase costs. Furthermore, if operation data is sent from multiple devices at the same time, there is a risk of data interference. Therefore, it is necessary to realize a two-way remote control system that is easier to use in a system of multiple devices such as a stereo system.

In view of the above-mentioned conventional problems, the present invention provides a stereo system including a two-way remote control system that is easier to use in a stereo system in which a plurality of devices are combined.

Means for Solving the Problems The present invention provides a stereo system consisting of a plurality of audio devices such as a power amplifier, a tuner, a CD player, a cassette deck, and a DAT, in which the control sections of each device are connected by a bus line. , between the control signal receiving section and data signal transmitting section built into each device or provided as a separate unit, and the data signal receiving section and control signal transmitting section provided in the remote control, control signals and operation of the device are transmitted. A remote control system configured to transmit status data signals.

Furthermore, a display section provided on the remote control that displays the contents of data signal reception displays operation data of the device to which the selector switch of the power amplifier is set.

In addition, the data signal transmitter periodically checks the setting position of the power amplifier selector switch at regular intervals. It is designed to send data to the remote control.

Furthermore, each device sends its own operating state data to a data signal transmitter when its own state changes, and the data signal transmitter transmits the operating state data to the remote controller.

Further, the remote control is configured to turn off the power to the data signal receiving section and the display section after a certain period of time has elapsed since no transmission from the data signal transmitting section was received.

Effect of the Invention With the above configuration, the present invention allows the operating state of a stereo system composed of a plurality of devices to be checked even from a location away from the main body of the device.

Furthermore, it is possible to display the operating status of the currently operating device that is most wanted to know in a stereo system composed of a plurality of devices.

Furthermore, even if the operating data signal cannot be received temporarily due to an obstacle, the operating status of the device can be displayed after a certain period of time.

Furthermore, even when the main body of the device is operated directly, the operating status can be displayed on the remote control. In addition, if the operation data signal is continuously blocked by an obstacle or the remote control is moved to a place where the operation data signal cannot reach, and bidirectional operation is no longer possible, the power consumption of the remote control is automatically reduced to the necessary minimum. It can be held in place.

Embodiment FIG. 1 shows an embodiment of the present invention. In the figure, 1 is a tuner, 2 is a power amplifier, 3 is a CD player, 4 is a cassette deck, and 5 is a DAT. A control signal receiving section 6 and a data signal transmitting section 7 are built into one tuner. The devices 1 to 5, the control signal receiving section 6 and data signal transmitting section 7 inside the tuner, and the tuner section 1' are all connected by eight bus lines.

Reference numeral 9 denotes a remote controller, which includes a control signal transmitting section 10, a data signal receiving section 11, a display section 12 for displaying the contents of received data signals, a control section 13, and an operation section 14. 15 represents the movement of a signal using infrared rays, and FIG. 2 represents the information content of the bus line 8. That is, the data signal transmitter 7
makes a status request to the power amplifier 2, and the power amplifier 2 responds by sending amplifier data to the data signal transmitter 7. In addition, the data signal transmitter 7 transmits signals to each device (tuner 1, CD player 3, cassette deck 4).
, DAT5), and in response, each device sends each device data to the data signal transmitter 7 in response.

The control signal receiving section 6 receives command data transmitted from the remote controller and sends it to each device. The data signal transmitting section 7 and the control signal receiving section 6 perform two-way communication with the remote control 9 using a signal 15 using infrared rays.

FIG. 3 shows the operation of the data signal transmitter 7 in a professional chart.

First, when the power is turned on, the start-up time (1
After waiting for a few seconds), the data signal transmitter 7 sends a status request to the power amplifier 2 using the bus line. In response, the power amplifier 2 sends amplifier data to the data signal transmitter 7 in response. This amplifier data is received, converted to infrared data, and sent to the remote control. Next, the current position of the selector switch of the power amplifier is determined from the amplifier data.

Next, a status request is made to the device set by the selector switch of this power amplifier, and each device responds by sending device data to the data signal transmitter 7. For example, if the current selector switch position of the power amplifier is the tuner, the data signal transmitter 7 makes a status request to the tuner, and in response, the tuner sends data such as the current receiving frequency and preset channel. is sent back to the data signal transmitter 7. The data signal transmitter 7 receives the data of the device set by the selector switch of this power amplifier,
It converts into infrared data and sends the data of the device set with this selector switch to the remote control.

Next, the data signal transmitter 7 sets a timer, waits for a certain period of time to elapse, and repeats the above operation. In the embodiment, this operation is repeated every minute.

Further, when data of each device is sent from each device to the data signal transmitter 7, the data signal transmitter 7 receives the data of this device, converts it into infrared data, and sends the data of this device to the remote control. Send.

FIG. 7 shows a flowchart of a portion in which each device (tuner 1, CD player 3, cassette deck 4, DAT 5) and power amplifier 2 transmits their own operating state data. When each device (tuner 1, CD player 3, cassette deck 4, DAT 5) and power amplifier 2 receives a status request, they send their own operating status data to the data signal transmitter 7. send. Further, when its own operating state changes, the operating state data is sent to the data signal transmitter 7.

FIG. 5 shows a flowchart of a portion of the remote control that receives and displays operation data of the stereo stem.

First, when some received signal is input to the data signal receiving section 11 of the remote control, it is determined whether it is amplifier data or not. If it is amplifier data, the timer is reset, then all of the amplifier data is received, and the received data is stored in a display memory provided for the amplifier. Next, based on the received data, the power amplifier selector position and other amplifier data, such as polyum data, are determined.
The status of the muting switch is displayed on the display section of the remote control. Next, the selector information of the received amplifier data is compared with the memory selector information before being received to determine whether the selector has changed. If the selector has changed, data for the device set by the changed selector switch is selected from a display memory provided for each device inside the remote controller and displayed on the display section of the remote controller.

If it is not amplifier data, set the timer.

Then, it is determined whether the timer has elapsed for 5 minutes. If 5 minutes have not elapsed, each other device is determined from the received data and received as each device data. The received data is then stored in a display memory provided for each device.

For example, in the case of a tuner, data such as the current reception frequency and preset channel number are received and stored in the tuner's display memory. Next, it is determined whether this device data corresponds to the device for which the selector switch of the power amplifier is set based on the previously received and stored amplifier data. If the device is a set device, the operating state of the device is displayed on the display section of the remote control based on the received data of the device. For example, if the selector switch of a power amplifier is a tuner, the data for that amplifier has already been received and stored in the display memory, and the selector is displayed on the remote control's display as "Tuner". It is determined from the data in the display memory that the selector switch of the power amplifier is the tuner, and if the received data is from the tuner, the operating state of the tuner, that is, the receiving frequency and preset, is determined based on the received data. The channel number is displayed on the remote control's display. After that, if the received data is a CD player, it is determined that it is a CD player because it is not the device that sets the selector switch of the power amplifier, and it is received as data for the CD player. The received data is only stored in the provided display memory and is not displayed. In other words, all data sent from each device is received and stored in the display memory provided for each device, but only the data of the device set with the power amplifier's selector switch is displayed. be. However, all the latest operating status data of other devices is received and already stored in the display memory provided for each device. Here, when switching from the power amplifier selector switch or tuner to the CD player, first, the power amplifier sends the amplifier operating status data to the data signal transmitter 7, and the data signal transmitter 7 converts it into infrared data. and sent to the remote control. The selector information of the received amplifier data is compared with the selector information of the memory before being received to determine whether the selector has changed. As a result, the selector changes from tuner to CD.
It is determined that the player has changed, and the data of the device set by the selector switch after the change is displayed from the display memory provided for each device inside the remote control, that is, C
D Select the player data and display it on the remote control display. In other words, when the selector switch of the power amplifier is switched from the tuner to the CD player, the display on the remote control immediately changes to the latest operating state of the CD player at that time. If the timer has elapsed for 5 minutes,
That is, if data cannot be continuously received from the power amplifier for 5 minutes, the remote control cuts off the power to the receiving circuit and display circuit, and enters a low current consumption state.

FIG. 6 shows an embodiment of the display of the remote control display section of the present invention. In (a), the power amplifier selector is a tuner and is currently receiving FM frequency 85.1MH2, indicating that this is preset channel 12. (
In b), the power amplifier selector indicates that the CD player is currently playing track number 10. In (C), the power amplifier selector is a cassette deck.
The display indicates that the camera is currently in recording pause. (d) is the power amplifier selector or DAT, which indicates that no tape is currently installed.

Effects of the Invention With the configuration of the embodiment described above, the present invention allows the operating state of a stereo system composed of a plurality of devices to be checked even from a location away from the main body of the device. In addition, in a stereo system consisting of multiple devices, it displays the operating status of the currently operating device that you most want to know, that is, the device that is currently in front of you, that is, the device whose power amplifier selector switch is set. can be done.

Furthermore, even if the operating data signal cannot be received temporarily due to an obstacle, etc., the amplifier data and power amplifier selector setting device data are periodically sent to the remote control, so the operating state of the device can be restored to normal after a certain period of time. It can be displayed as follows.

Furthermore, even when the main body of the device is operated directly, when the state of each device changes, the operation data is sent to the remote control each time, so the remote control can display the operating state.

In addition, if the operation data signal continues to be blocked by an obstacle or the like, or the remote controller is moved to a place where the operation data signal cannot reach, and bidirectional operation is no longer possible, in this example, the operation data signal is continuously blocked for 5 minutes and periodically If the amplifier data that was supposed to be sent no longer arrives, the power to the receiver circuit and display circuit of the remote control is automatically shut off, reducing power consumption to the necessary minimum.
