BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a remote control device for transmitting a remote control signal from a wireless transmitter, receiving the remote control signal at a remote position, and controlling a predetermined load. .

[0002]

2. Description of the Related Art Conventionally, as this type of remote control device, a signal is generally transmitted and received by transmitting and receiving an optical signal as disclosed in Japanese Utility Model Application Laid-Open No. 2-101687. In these, the light emitting unit of the transmitter is operated to face the light receiving unit side of the receiver in order to transmit and receive an optical signal.

[0003]

However, in the above-mentioned conventional technique, since optical signals are transmitted and received, there is a problem that reception becomes impossible if there is a failure in the transmission path of the optical signals. To solve this problem, transmission of a sound wave signal using audible sound of a predetermined frequency is considered. On the other hand, the transmitter is required to have a function of confirming the operation content in order to prevent erroneous operation and erroneous operation of a person who is not proficient in operation. Therefore, the actual Kaihei 3-515
As in the technique disclosed in Japanese Patent Application Publication No. 94-94, there is a technique in which the operation content is confirmed by a display, but there is a problem that the visual confirmation is troublesome. The present invention has been devised in view of the above problems, and can reliably transmit a signal even if there is an obstacle in a signal transmission path between a transmitter and a receiver, and makes operation of the transmitter extremely easy. It is an object of the present invention to provide a remote control device that can be checked.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings. In FIG. 1, 1 is a transmitter, and 2 is a receiver. The transmitter 1 is, for example, configured to be portable and small, and includes a plurality of operation switches 3a and 3 such as touch switches.
, 3n, and a transmission control unit 5 which receives a switch signal of the operation unit 3 and reads corresponding audio data from the data reader 4. The data reader 4 reads audio data written on a movable storage medium 6 such as an IC card or a magnetic disk by a data writer 19 described later. The transmission control unit 5 has a function of reading audio data corresponding to a switch signal of the operation unit 3 and deriving the audio data to the input side of the audio generation unit 8 via the digital / analog converter 7, and is configured by, for example, a microcomputer. . The audio generation unit 8 generates an audio signal based on the audio data input from the transmission control unit 5,
The signal is amplified by the amplifier 9 and output to the speaker 10.

[0006] The receiver 2 includes a microphone 11 for collecting sound.
And an audio processing unit 13 for inputting an audio signal output from the microphone 11 via the amplifying unit 12 and processing it as audio data.
And a reception control unit 15 for inputting audio data output from the audio processing unit 13 via an analog / digital converter 14 and performing control processing. In the receiver 2,
Reference numeral 16 denotes an operation unit, and a plurality of operation switches 16a, 16 such as touch switches individually corresponding to the operation switches 3a, 3b,..., 3n of the operation unit 3 in the transmitter 1.
.., 16n. Reference numeral 17 denotes a registration switch, and reference numeral 18 denotes a write switch, which is manually operated. Reference numeral 19 denotes a data writer for writing audio data to the storage medium 6.

The reception control unit 15 stores the audio data in the storage unit 2
0, a function of writing the registered voice data registered in the storage unit 20 to the storage medium 6 by the data writer 19, and a function of storing the voice data transmitted from the transmitter 1 and the registered voice data. It has a function of outputting a control command to the load control unit 21 when they match, and a function of outputting a control command to the load control unit 21 in response to a switch signal of the operation unit 16. Configure with computer. The load control unit 21 controls the loads 22a, 22b,..., 22n corresponding to the switch signals of the operation units 3 and 16 based on the control command of the reception control unit 15.

Next, the operation when the reception control unit 15 is constituted by a microcomputer in the configuration of the above embodiment will be described with reference to the flowchart shown in FIG. When the routine shown in FIG. 2 starts, the reception control unit 15 of the receiver 2 first sets the registration switch 17 to O in step 101.
It is determined whether or not N. When the registration switch 17 is ON, the process proceeds to the step of voice registration means indicated by a virtual line frame 102 and proceeds to step 103. In step 103, the operator inputs switch signals of arbitrary operation switches 16a, 16b,..., 16n selected on the operation unit 16. Next, in step 104, step 103
Input the audio data corresponding to the input switch signal. That is, at this point, the audio signal collected by the microphone 11 is amplified by the amplifier 12 and
The data is processed into clear audio data from which noise and the like have been removed, and is converted into a digital signal by the analog / digital converter 14 and input to the reception control unit 15.

Next, at step 105, the reception control unit 15
The so-called speech words in the speech data input to the storage unit 20 are registered in the storage unit 20. Next, in step 106, the sound in the voice data is analyzed, and in step 107, it is converted into a voice pattern. In step 108, this voice pattern is registered in the storage unit 20. After execution of step 108, the process returns to step 101. Thus, when the registration switch 17 is turned on,
.. 16n by arbitrarily selecting and operating each of the operation switches 16a, 16b,..., And 16n. Is stored in the storage unit 2 as registered voice data.
0 is registered.

Next, at step 101, the registration switch 17
Is determined to be OFF, the process proceeds to step 109. In step 109, the write switch 18
In the case of N, the process proceeds to the step of the storage medium writing unit indicated by the virtual line frame 110 and proceeds to step 111. In steps 111 and 112, the registered voice data and the registered voice pattern, which are the registered voice data, are read from the storage unit 20. Next, in step 113, each registered voice data read from the storage unit 20 is written into the storage medium 6 by the data writer 19. After execution of step 113, the process returns to step 101. As described above, when the registration switch 17 is turned off and the write switch 108 is turned on, the registered voice data can be written to the storage medium 6. Then, the storage medium 6 is mounted on the data reader 4 of the transmitter 1 and read out, whereby the operation switches 3a, 3b,.
n is stored as audio data corresponding to n.

Next, the registration switch 17 and the write switch 1
If both are OFF, the process proceeds to step 114.
In this state, when the operator operates the operation unit 3 with the transmitter 1 and inputs a switch signal of any of the operation switches 3a, 3b,..., 3n, the transmission control unit 5 responds to the switch signal. The audio data is read from the storage medium 6 by the data reader 4 and is converted into a digital / analog converter 7
An omnidirectional audio signal, for example, “light-on”, “wiper-on”, etc., is generated from the speaker 10 via the audio generation unit 8 and the amplification unit 9. At this time, the operator can easily confirm the operation content by voice. Further, the audio signal is omnidirectional, and even if there is an obstacle between the transmitter 1 and the receiver 2, the audio signal transmission between the two is reliably performed between the speaker 10 and the microphone 11. In the receiver 2, the microphone 11 collects the audio signal, and
The audio data is output to the reception control unit 15 via the audio processing unit 13 and the analog / digital converter 14 as audio data.

When receiving the voice data, the reception control unit 15 determines in step 114 that there has been voice input, and proceeds to the step of voice recognition comparing means indicated by a virtual line frame 115, and proceeds to step 116. In step 116, the input voice data is temporarily stored, and the flow advances to the next step 117. In step 117, the sound in the sound data is analyzed, and further in step 118, the sound pattern is converted into a sound pattern.
Compare with the registered voice pattern registered in. In step 119, when it is determined that the two voice patterns match, it is determined that the voice signal is the voice signal emitted from the transmitter 1, and the process proceeds to step 120. In the case of a mismatch, the process returns to step 101. In step 120, the voice data temporarily stored is read out, compared with the registered voice words registered in the storage unit 20, and when it is determined that they match, in the next step 121, the voice data corresponding to this registered voice word is corresponded. After controlling the loads 22a, 22b,..., 22n, the process returns to step 101. If it is determined that the values do not match, the process returns to step 101.

On the other hand, if it is determined in step 114 that voice data is not input, the process proceeds to the step of the direct control means indicated by a virtual line frame 122, and proceeds to step 123. In step 123, the operator operates the operation unit 16 of the receiver 2 to select any operation switch 16a,
.., 16n. Next, at step 124, the loads 22a, 22b,..., 22 corresponding to the switch signal inputted at step 123
n is controlled via the load control unit 21 and
Return to Thus, desired loads 22a, 22b,..., 22n can be directly controlled by the operation unit 16 of the receiver 2.

As described above, by transmitting an audio signal from the transmitter 1 or operating the operation unit 16 of the receiver 2,
Each of the loads 22a, 22b,..., 22n can be controlled. In addition, by emitting a voice that matches the registered data registered in the storage unit 20, the loads 22a, 22b,..., 22n can be controlled without using the transmitter 1. Also, since the same voice data is used in the transmitter 1 and the receiver 2, the voice recognition rate in the voice recognition comparing means 115 of the receiver 2 is improved, and erroneous control can be prevented.

In the above-described embodiment, the registered voice data registered in the storage unit 20 of the receiver 2 is not limited to the method of inputting through the microphone 11; It may be registered by synthesis. The audio data used in the transmitter 1 is
Speech recognition comparison means 1 in reception control unit 15 of receiver 2
15 is not limited to a method in which the content can be read from the storage medium 6 by the data reader 4 as long as the content can be recognized by voice compared with the registered voice data.
