Abstract

PURPOSE:To eliminate an operation mistake, by providing a function to confirm whether or not a normal remote control is possible. CONSTITUTION:A transmission system 21 produces a prescribed instruction signal through an instruction keyboard 22, and at the same time a reception system 25 produces through a test key part 22a a signal to confirm whether or not the normal reception is possible for the instruction signal given from the system 21. Both the instruction signal and the confirming signal are transmitted from a transmitting circuit 24 via a modulating circuit 23 in the form of a signal having a proper code bit respectively. The system 25 receives both instruction and confirming signals from the system 21 through a receiving circuit 26 and allots these signals to a confirming signal recognizer 28 and a device 29 to be controlled via a demodulating circuit 27. The recognizer 28 discriminates whether or not the confirming signal is correctly received and demodulated as a proper bit code. When this reception and demodulation is decided normal, it is decided that the instruction signal can also be received in a normal way.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in wireless remote control devices applicable to electronic devices in general (1).

[Technical background of the invention]

Recently, electronic equipment in general including audio equipment, television receivers, video tape recorders, etc. Wireless remote control devices are becoming widely adopted.

FIG. 1 shows a schematic configuration of a conventionally known wireless remote control device. In other words, the command key 12 for sending (N system)
A predetermined command signal from the transmission circuit 14 can be wirelessly transmitted from the transmission circuit 14 to the outside via the control circuit 13 (-).

Further, the receiving thread 15 is configured such that the receiving circuit 16 receives the command No. 44 from the above-mentioned sender <M-system engineer" and then supplies it to the controlled device 18 via the return subcircuit 11.

[Problems with background technology]

However, in the conventional wireless remote control device as described above, if the relative positional relationship between the transmitting system 11 and the receiving system 15 changes, remote control operation becomes impossible (doubling or malfunction may occur). He had the tenacity to make things happen.

In other words, with this Yuzu wireless remote control device WIL. General (Ni-ukehaku thread-15. is fixed and operated while frequently moving the position of the transmitting system-L), but depending on the position of the transmitting system 1, there may be obstacles, interference waves, etc. This is because there are many cases where the receiving system 15 is unable to normally receive the command signal from the transmitting system 11 due to the influence of the above.

For this reason, it would be effective to eliminate operational errors if a function is provided in advance to check whether normal remote control operation can be performed between the sending string 11 and the receiving system 15, but conventionally No consideration was given at all.

[Purpose of the invention]

Therefore, this invention was made in consideration of the above points, and has been developed to provide an extremely good wireless remote control that has been improved to eliminate operational errors by being equipped with a function to check whether the remote control operation is normal or not. The purpose is to provide a control device.

[Summary of the invention]

That is, in the wireless remote control device according to the present invention, the transmitting system is provided with means for enabling the receiving system to send out a signal for confirming whether or not it can correctly receive the command signal from the transmitting system.

The receiver (M thread) is characterized by having a means for confirming from the transmitting system (gS1) to confirm whether or not it can be received normally.

[Embodiments of the invention]

An embodiment of the present invention will be described in detail below with reference to the drawings.

That is, as shown in FIG. 2 ('-transmission system 2), a command keyboard 22 is configured to be able to generate a predetermined command signal, and a test key part 22m is used to generate a reception system 2 (to be described later).
It is possible to generate a confirmation number 48 as to whether or not the transmission system 5 can normally receive the command signal from the transmission system 2. The predetermined command number from the command key code 22 and the confirmation signal from the test key part 22m are sent to the outside from the transmitting circuit 24 via the modulation circuit 23 as signals each having a unique code pit. be done.

In this case, the code bit of the confirmation signal is set so as not to be influenced by other command signals.

Then, the reception system 25 receives the confirmation signal and other command signals from the transmission system 21 through the reception circuit 26 and sends them to the demodulation circuit 27.
The bit codes are converted back to the original command signal via the control unit 22, and can be distributed and supplied to the confirmation signal recognizer 28 and the controlled equipment 29.

In such a configuration, the receiving system 25 is usually fixed and the transmitting system 21 is moved and operated as necessary.

In this case, in a state where the position of the transmission system 21 can be used, the test key part 221 is used before sending out the command signal.
A confirmation signal is sent by operating the .

Then, the reception system 25 receives the confirmation signal from the transmission thread 21 and supplies it to the confirmation signal recognizer 28 in order to recognize whether or not it can normally receive other command signals. In this case, the confirmation signal recognizer 28 determines whether the confirmation signal is correctly received and demodulated as a unique bit code, and if it is normal, other command signals can also be received normally. The transmission system 21 side (
It is designed so that it can be recognized twice.

This ensures that the transmitter can continue to send out other command signals and correctly remotely control the controlled device 29 to the desired state.

If the confirmation signal recognizer 28 does not give a display or electronic sound to recognize that normal reception is possible, move the transmission thread 21 to a position where it is given and then perform the command operation. This is a good idea, and it is equipped with a function to confirm whether or not normal reception is possible in advance.C: It is possible to eliminate undesirable operational errors.

It goes without saying that this invention is not limited to the embodiments described above and disclosed, and that various modifications and applications can be made without departing from the gist of the invention.

For example, in order to generate a confirmation signal in the transmission system, it is not necessary to provide a dedicated test key, and confirmation mode can be obtained by operating other command operation keys in a specific combination. You can do it like this.

Further, the confirmation signal recognizer may also be used for recognition when receiving other command signals, and in this case, the output from the receiving circuit may be directly guided to the recognizer.

〔Effect of the invention〕

Therefore, as described above in detail, according to the present invention, an extremely good wireless remote control device is provided which has been significantly improved to eliminate operational errors by providing a function to check whether or not normal remote control operation can be performed. It becomes possible to provide
