DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a remote control device for remotely controlling AV equipment such as a VTR and home electrical equipment such as an air conditioner (hereinafter referred to as a controlled device).

[Conventional technology]

Conventionally, in this type of remote control device, as shown in FIG. 3, a remote control transmitting device 21 includes a key matrix 17 and means 18 for generating a key matrix scanning signal and a remote control transmitting signal corresponding to a pressed key. ,
The remote control receiving device i! is equipped with an element 20 that intermittently transmits light emission 20a such as infrared rays according to a transmission signal, and one means for displaying the transmission signal. 24 is an element 2 that receives a remote control transmission signal (light emission 20a) using a light receiving diode or the like.
3, and means 22 for supplying the received signal to the controlled device 25.

The operation shown in FIG. 3 will be explained with reference to FIG. When any key in the key matrix 17 is pressed, a key manual signal 17a is generated from the key matrix 17 and inputted to the means 18 for generating a remote control transmission signal. The means 18 for generating a remote control transmission signal outputs a key matrix scanning signal 18a, recognizes a pressed key, and generates a remote control transmission signal corresponding to the key. The generated remote control transmission signal is sent to means 19 for displaying the remote control transmission signal.
At the same time, it is transmitted to the remote control receiving device 24 as a transmission output 20a by the transmitting element 20. In the remote control receiving device 24, the receiving element 23 receives the remote control transmission signal 20a transmitted from the remote control transmitting device 21. The received remote control transmission signal is sent to the receiving means 22.
[Problems to be Solved by the Invention] The above-described conventional remote control device is configured to convert a signal to a control signal for controlling the controlled device 25 and supply it to the controlled device 25. There is no function to check whether the transmission to 24 is accurate, and the only way to guess is whether or not the controlled device itself is accurately controlled. That is, in the remote control transmitting device, there is a problem in that even if an erroneous signal is transmitted, there is no means to confirm it.

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide a remote control device that can confirm that accurate signals have been transmitted.

It consists of a remote control transmitting and receiving device.

〔Example〕

Next, one embodiment of the present invention will be described with reference to the drawings.

Referring to FIG. 1, a remote control device according to an embodiment of the present invention includes a first remote control transmitting and receiving device 8 and a second remote control transmitting and receiving device 15 coupled to a controlled device 16. The first remote control transmitting/receiving device 8 includes a key matrix 1 similar to the conventional remote control transmitting device shown in FIG. It has a transmitting element 6 that emits and transmits the output, further includes a means 3 for receiving a remote control signal via a receiving element 7, a means 4 for comparing the transmitted signal and the received signal, and a comparison by the comparing means 4. A means 5 for displaying the results is also added. The second remote control transmitting/receiving device 15 has a means 9 for receiving the transmitted signal 6a via the receiving element 13 and supplying the received signal to the controlled device in the same manner as the conventional remote control receiving device, and further includes means 9 for receiving the received signal 6a through the receiving element 13 and supplying the received signal to the controlled device. Storage means 10 and first remote control transmitting/receiving device 8
means 11 for detecting that a specific confirmation signal has been received from among the transmitted signals 6a; Means 1 of transmitting via 14
2 is added.

Next, the operation of this embodiment will be explained with reference to FIG. 2 as well. When any key in the key matrix 1 is pressed, a key human input signal 1a is generated from the key matrix 1 and inputted to the means 2 for generating a remote control transmission signal. The means 2 for generating a remote control transmission signal outputs a key matrix operation signal 2a, recognizes a pressed key, and generates a remote control transmission signal corresponding to the key. The generated remote control transmission signal is transmitted as a signal 6a via the transmission element 6, and is also input to the comparison means 4 and stored at the same time. On the other hand, the second remote control transmitting/receiving device 15 receives the remote control transmitting signal 6a transmitted from the first remote controlling transmitting/receiving device 8.
is input to the receiving means 9 via the receiving element 13. The receiving means 9 supplies the received signal to the controlled device 16 and stores it in the storage means 10 . Next, when a specific confirmation key among the keys in the key matrix 1 is pressed, the first remote control transmitting/receiving device 8 transmits the remote control transmission signal 6a in the same way as when pressing any key.

However, only when the confirmation key is pressed, storage of the transmitted signal in the comparison means 4 is prohibited, and the stored contents of the comparison means 4 are retained. The second remote control transmitting/receiving device 15 similarly receives the transmitted signal 6a, but the receiving means 9 inputs the received signal to the controlled device 16 and the storage means 10 as well as to the confirmation signal detecting means 11. The confirmation signal detection means 11 outputs a detection signal 11a, and the output 11a transmits the received signal stored in the received signal storage means 10 to the first remote control transmitting/receiving device as a transmitted signal 14a via the transmitting means 12 and the transmitting element 14. Send to 8. The first remote control transmitting/receiving device 8 inputs the transmitted transmission signal 14a to the receiving means 3 via the receiving element 7. The received signal inputted to the receiving means 3 is compared with the transmitted signal stored in advance in the comparing means 4, and the result is inputted to the displaying means 5 and displayed. This allows the operator of the remote control transmitting/receiving device 8 to confirm on the display means 5 within the device 8 that the transmission has been performed correctly.

〔Effect of the invention〕

As explained above, according to the present invention, means for receiving a signal transmitted from a remote control receiving device and means for comparing the transmitted signal and the received signal are added to the remote control transmitting device, and the remote control receiving device By adding means for storing received signals and means for transmitting the signals to the remote control transmitting device, it becomes possible to exchange data between the remote control transmitting device and the remote control receiving device, and the transmission from the remote control transmitting device becomes possible. This has the advantage that the contents can be confirmed not only on the controlled device itself but also on the remote control transmitting device.
