Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a wireless remote control device.

[Prior Art] Recently, automobile televisions have become popular. This automotive television needs to have a large number of channels because the vehicle is mobile. That is, since the frequency range used for broadcasting differs depending on the driving area, it is necessary to prepare 62 channels, and many selection switches are required for this purpose. Therefore, the automobile television is equipped with a channel call/preset switch, which allows a desired channel to be stored in a storage area of the memory, and which can also read out the desired channel. On the other hand, wireless remote control devices are also installed in automobile televisions. Then, when you press the channel call/preset switch on the transmitter of the remote control device once,
As shown in FIG. 7, the code rA assigned to the switch is synchronized with the on operation (press operation) of the switch.
J is transmitted as a remote control signal (for example, infrared rays), and the receiver side receives the signal and performs an operation of calling up a channel stored in the storage area of the memory. If you keep pressing the channel call/preset switch on the transmitter, the assigned code rAJ will be sent out at regular intervals as shown in Figure 7, or the code r will be sent initially.
AJ is sent, and then the code indicating continuous pressing (in Figure 7, "
(indicated by "continuous") is transmitted at regular intervals, and the receiver can change the channel settings by counting the rAJ or continuous codes transmitted at the regular intervals. .

[Problem to be Solved by the Invention 1] However, when attempting to change the channel settings by pressing the channel call/preset switch provided on the remote control device for a certain period of time, the C remote control signal (infrared rays) was interrupted. There was a problem that normal operation could not be performed in such a case. In other words, when the receiver side counts code signals at regular intervals or continuous code signals sent after a signal synchronized with channel call/preset switch ON operation (press operation) from the transmitter, transmission/reception is required. If an obstacle crosses the signal path between the devices or if direct sunlight hits the receiver, the code signal or continuous code signal will not be received by the receiver and the channel preset operation (setting content rewriting operation) may not be performed correctly. could not.

SUMMARY OF THE INVENTION An object of the present invention is to provide a remote control device that is less susceptible to disturbances and can reliably perform operations associated with switch operations.

[Means for Solving the Problems 1] The present invention provides a remote control device comprising a transmitter having an on/off switch and a receiver that performs a plurality of operations based on an on operation of the on/off switch. A timer provided in the transmitter and configured to time the ON time of the on/off switch; and a comparison device provided in the transmitter to compare the ON time of the ON/OFF switch determined by the timer with a predetermined time. and outputting a first command signal provided in the transmitter and causing the receiver to perform a first operation when the on-off time of the on-off switch is less than a predetermined time by the comparison means, and , and a control means for outputting a second command signal for causing the receiver to perform a second operation when the ON time of the on-off switch is longer than a predetermined time. It is something to do.

[Function] A timer provided in the transmitter measures the on time of the on/off switch, and a comparison means provided in the transmitter compares the on time of the on/off switch by the timer with a predetermined time. and a control means provided in the transmitter outputs a first command signal that causes the receiver to perform the first operation when the ON time of the on-off switch is less than a predetermined time by the comparison means. At the same time, when the ON time of the on/off switch is longer than a predetermined time, a second command signal is output that causes the receiver to perform the second operation.

As a result, the receiver side operates based on the command.

[Example 1] Hereinafter, the present invention will be embodied in an infrared wireless remote control device (hereinafter simply referred to as a remote control device) provided in an automobile television, and furthermore, a switch having the functions of the present invention will be used for channel calling and presetting. An embodiment embodied in a switch will be described with reference to the drawings.

As shown in FIGS. 1 and 2, the remote control device provided in the automobile television 1 includes a remote control transmitter 3 having a transmitting section 2 that emits infrared rays, and a remote control having a light receiver 4 provided in front of the television 1. It consists of a receiver 5.

The remote control transmitter 3 is equipped with an operation switch 6. The operation switch 6 includes a power switch 7, a channel selection up switch 8, a channel selection down switch 9, a volume up switch 10, a volume down switch 11, and a channel call/preset switch (as an on/off switch).
12 and 13 (hereinafter simply referred to as a switch to Bricella 1). The power switch 7 is a switch for turning the television 1 on and off. The channel selection up switch 8 and the channel selection down switch 9 change the channels up and down one by one.
The volume up switch 10 and the volume down switch 11 are switches for raising and lowering the volume.

Each of the preset switches 12 and 13 stores the current channel in the memory 16 provided on the receiver 5 side when the switch 12 or 13 is pressed for a certain period of time or longer.
If the preset switch 12 or 13 is pressed for less than a certain period of time, the stored channel is read out.

In addition, the remote control transmitter 3 includes a microcomputer (hereinafter simply referred to as a microcomputer) as a comparison means and a control means.
14, and the microcomputer 14 is provided with a memory (not shown) storing a control program and a timer 14a as a time measuring means. The microcomputer 14 detects the depression of each of the switches 7 to 13, performs various fault handling operations according to the control program, and outputs a remote control signal to the transmitter 2. That is, when the N source switch 7 is pressed, the remote control signal of the code corresponding to the switch 7 is transmitted only once (single transmission), and the channel selection up/down switches 8, 9, gf11 up/down switch 10. While 11 is pressed down, the remote control signal of each code corresponding to the switch 8, 9, 10, 11 continues to be transmitted at regular intervals (continuous transmission). Furthermore, the microcomputer 14
performs a process to be described later based on the pressing operation (on operation) of the preset switch 12.13, and sends out a predetermined remote control signal.

The transmitter 2 of the remote control transmitter 3 is equipped with an infrared light emitting diode for converting the remote control signal sent by the microcomputer 14 into infrared light, and a transistor for driving the infrared light emitting diode. The transmitter 2 receives the remote control signal sent by the microcomputer 14, modulates it into an infrared light signal according to the content of the remote control signal, and outputs the modulated signal.

On the other hand, the light receiving section 4 of the remote control receiver 5 is connected to the remote control transmitter 3.
It receives the infrared light output from the transmitter 2, demodulates it into a remote control signal, and outputs it to the control circuit 15. The control circuit 15 turns on/off the power, selects a channel, and adjusts the sound group based on the remote control signal from the light receiving section 4, depending on the content of the signal. A memory 16 is connected to this control circuit 15, and the control circuit 15 performs a readout operation of the setting channel stored in the menu 16 in response to a signal input by operating the pre-certifier switch 12.13. Perform a change operation.

Next, the process based on the pressing operation of the preset switch 12 of the microcomputer 14 of the remote control transmitter 3 will be explained based on the flowchart shown in FIG.

The microcomputer 14 switches preset switch 1 at step 100.
2 is pressed, and the preset switch 12 is pressed.
When is turned on (pressed), timer 1 is turned on in step 101.
4a starts the timer counting operation. Microcomputer 1
4, in step 102, it is determined whether the count time is longer than a preset predetermined time T (for example, 2 seconds), and in step 103, if the pressing time is less than a certain time, the preset switch 12 is turned off. Determine whether or not it has been done. When the microcomputer 14 determines in step 103 that the pre-switches 1 to 12 are turned off, it outputs a remote control signal A1 to call up the channel stored in the memory 16 in step 104.

If the microcomputer 14 determines in step 102 that the pressing time has reached the predetermined time T, it outputs the remote control signal A2 to store the channel in the memory 16 in step 105. Thereafter, the microcomputer 14 confirms that the preset switch 12 has been turned off in step 106, and returns to step 100.

FIG. 4 shows remote control signals A1. The output state of A2 is shown. That is, the preset switch 12 is
When the button is turned off, it outputs the remote control signal A1 as a first command signal to call up the channel stored in the memory 16 when the button is turned off, and also outputs the remote control signal A1 as a first command signal to call up the channel stored in the memory 16. A remote control signal A2 is sent as a second command signal to be stored in the memory 16.

As a result, the remote control signals AI and A2 sent out in steps 104 and 105 are converted into infrared rays by the transmitting section 2 and output, and are received by the light receiving section 4 of the remote control receiver 5.
In the control circuit 15, the action V' of the command content is carried out.
.

In this way, in this embodiment, the timer 1 is set on the transmitter 3 side.
4a to press the preset switch 12.13 and a predetermined time T.
．． 13 is less than the predetermined time 1, the remote control receiver 5 outputs a read command signal for the setting channel stored in the memory 16, and the preset switch 12.13 is pressed for less than the preset time (on time). ) exceeds a predetermined time T, a command signal for changing the set channel stored in the memory 16 of the remote control receiver 5 is output. Therefore, when controlling the device by counting successive remote control signals after the signal output in synchronization with the on-operation of a switch on the receiver side, as in the past, continuous remote control signals at the receiver side are The preset operation did not occur if the light path was blocked by passing an obstacle or by direct sunlight illuminating the light receiving section, but this does not occur and it can be operated reliably. In other words, instead of combining the conventional signals A to create a new command, we output individual command signals, so that subsequent processing (memory reading) can be performed without starting previous processing (channel reading). rewriting).

In addition, the remote control signal that is sent even though the preset switch is pressed continuously is only a signal that indicates whether or not it has been pressed for a certain period of time. Compared to continuing to send out remote control signals while the device is in use, less data is needed to be sent out, so the load on the battery can be significantly reduced and the life of the battery can be extended.

Note that this invention is not limited to the above embodiments,
For example, the remote control signals Al and A2 depending on the operation of the preset switch 12 may be sent out multiple times for confirmation as shown in FIGS. 5 and 6.

In addition, in the embodiment described in -F, channel presetting was explained, but regarding channel selection, if the switch is pressed for less than a certain period of time, automatic search will be performed, and if it is less than a certain period of time, manual selection will be performed. The same can be done in the same way.

Furthermore, in addition to the on/off function of the TV, the power switch also has an on-timer/off-timer function.When the power switch is held down for a certain period of time while the TV is on, an off-timer signal is sent, and if the power switch is pressed for a certain period of time while the TV is turned on, an off-timer signal is sent. If you continue, the timer setting time will change from 30 minutes to 60 minutes to 90 minutes.
It is also possible to send a remote control signal that sets the time from minutes to 120 minutes. Roughly speaking, if you press the power switch for a certain period of time when the TV is off, it will send out an on-timer signal, at which time the TV will turn on, and if you keep pressing it from then on, it will send out a remote control signal to set the timer time. (The TV may be turned off when the timer setting ends.) In other words, the present invention can be applied to a case where a function is used depending on how long one switch is pressed.

Further, in the above embodiment, the processing based on the operation of the preset switches 12 and 13 is performed by the program processing by the microcomputer 14 (
Although this is done using software (software), it may also be done using hardware using a circuit configuration.

Further, in the above embodiment, the remote control device is provided in a car television, but it can also be applied to a remote control device for home televisions, video, audio equipment, etc., or for car audio equipment, air conditioners, etc. It may be embodied in a remote control device.

Further, in the practical example described in -1-, a push-down switch that is turned on by being pressed is used as a switch provided in a remote control transmitter, but an optical switch such as a touch switch may be used. In short, it can be turned on or off by the operation of the Ministry of Utilization.
If it is an on/off switch that turns off, it can be turned off.

[Effects of the Invention] As described in detail above, the present invention exhibits an excellent effect in that it is less susceptible to external disturbances and can reliably perform operations associated with turning on a switch.
