Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a remote control device that transmits a remote control signal from a wireless transmitter, and the receiver receives the remote control signal at a remote position to control a predetermined load.

[0002]

[Prior Art]

 Conventionally, as a remote control device of this type, a signal is generally transmitted by transmitting and receiving an optical signal, as in the technique disclosed in Japanese Utility Model Laid-Open No. 2-101 687, for example. These are operated by directing the light emitting part of the transmitter toward the light receiving part of the receiver in order to transmit and receive an optical signal.

[0003]

[Problems to be solved by the device]

 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 optical signal transmission path. To solve this problem, transmission of a sound wave signal using an audible sound of a predetermined frequency can be considered. On the other hand, the transmitter is required to have a function to confirm the operation contents in order to prevent erroneous operation and erroneous operation by those who are not familiar with the operation, but it cannot be confirmed with a audible sound wave signal. Therefore, there is a technique for confirming the operation contents by a display as in the technique disclosed in Japanese Utility Model Laid-Open Publication No. 3-51594, but the visual confirmation remains a problem. The present invention has been made in view of the above problems, and can reliably transmit a signal even if there is an obstacle in the signal transmission path between the transmitter and the receiver, and it is extremely easy to operate the transmitter. The purpose is to provide a remote control device that can be confirmed to.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention compares a transmitter that transmits an omnidirectional voice signal corresponding to a predetermined operation with the received voice signal and a registered voice registered in advance. When it is determined that they match, the remote control device is configured with a receiver that controls the load corresponding to the registered voice.

【Example】

 A preferred embodiment of 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, of a portable and small size, and corresponds to an operation unit 3 including a plurality of operation switches 3a, 3b, ... 3n such as a touch switch, and a switch signal of the operation unit 3 being input. A transmission control unit 5 for reading the voice data to be read from the data reader 4 is provided. The data reader 4 is for reading voice data written in 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 voice data corresponding to the switch signal of the operation unit 3 and deriving the voice data to the input side of the voice generation unit 8 via the digital-analog converter 7, and is configured by, for example, a microcomputer. .. The voice generating unit 8 generates a voice signal based on the voice data input from the transmission control unit 5, amplifies the signal by the amplifying unit 9, and outputs the amplified signal to the speaker 10.

The receiver 2 includes a microphone 11 for collecting sound, a voice processing unit 13 for inputting a voice signal output from the microphone 11 via the amplification unit 12 and processing it as voice data, and the voice processing unit. A reception control unit 15 is provided for inputting the voice data output from 13 through the analog-to-digital converter 14 and performing control processing. In the receiver 2, 16 is an operation unit, and a plurality of operation switches 16a, 16b, such as touch switches individually corresponding to the respective operation switches 3a, 3b, ... 3n of the operation unit 3 in the transmitter 1. ... 16n. Reference numeral 17 is a registration switch, and 18 is a write switch, which are manually operated. A data writer 19 writes audio data in the storage medium 6.

The reception control unit 15 has a voice registration function of previously registering voice data in the storage unit 20, a function of writing registered voice data registered in the storage unit 20 into the storage medium 6 by the data writer 19, and a transmission function. The voice data transmitted from the device 1 is compared with the registered voice data, and when the two match, the function to output a control command to the load control unit 21 and the load control corresponding to the switch signal of the operation unit 16 It has a function of outputting a control command to the unit 21, and is configured by, for example, a microcomputer. 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, in the configuration of the above embodiment, the operation when the reception control unit 15 is configured by a microcomputer will be described based on the flowchart shown in FIG. When the routine shown in FIG. 2 starts, the reception control unit 15 of the receiver 2 first determines in step 101 whether the registration switch 17 is ON. If the registration switch 17 is ON, the process moves to the step of the voice registration means indicated by the virtual frame 102, and proceeds to step 103. In step 103, the operator inputs the switch signals of the arbitrary operation switches 16a, 16b, ..., 16n selected by the operation unit 16. Next, in step 104, voice data corresponding to the switch signal input in step 103 is input. That is, at this time, the voice signal collected by the microphone 11 is amplified by the amplifying unit 12, processed by the voice processing unit 13 into clear voice data from which noise and the like are removed, and digitally converted by the analog / digital converter 14. It is converted into a signal and input to the reception control unit 15.

Next, in step 105, the words of the voice in the voice data input to the reception control unit 15, so-called voice words, are registered in the storage unit 20. Next, in step 106, the sound in the above voice data is analyzed, further converted into a voice pattern in step 107, and this voice pattern is registered in the storage unit 20 in step 108. After step 108 is executed, the process returns to step 101. In this way, when the registration switch 17 is turned on, the operation switches 16a, 16b, ..., 16n are arbitrarily selected and operated, and the voice related to the operation is input from the microphone 11 after each switch operation. Thus, the voice word and the voice pattern corresponding to each of the operation switches 16a, 16b, ... 16n are registered in the storage unit 20 as registered voice data.

Next, when it is determined in step 101 that the registration switch 17 is off, the process proceeds to step 109. In step 109, when the writing switch 18 is ON, the process moves to the step of the storage medium writing means indicated by the frame 110 of the virtual line, and proceeds to step 111. In steps 111 and 112, the registered voice word 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 in the storage medium 6 by the data writer 19. After step 113 is executed, the process returns to step 101. As described above, when the registration switch 17 is turned off and the writing switch 108 is turned on, the registered voice data can be written in the storage medium 6. Then, the storage medium 6 is attached to the data reader 4 of the transmitter 1 and read out to hold as voice data corresponding to each operation switch 3a, 3b, ... 3n of the operation unit 3 in the transmitter 1. Will be done.

Next, when both the registration switch 17 and the writing switch 18 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 operation switch 3a, 3b, ... 3n, the transmission control unit 5 responds to this switch signal. The audio data to be read is read from the storage medium 6 by the data reader 4, and the omnidirectional audio signal, for example, “light on” is output from the speaker 10 via the digital / analog converter 7, the audio generation unit 8 and the amplification unit 9. , "Wiper on" ... At this time, the operator can easily confirm the operation contents 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 them is reliably performed between the speaker 10 and the microphone 11. In the receiver 2, the microphone 11 collects this voice signal and outputs it as voice data to the reception control unit 15 via the amplification unit 12, the voice processing unit 13, and the analog-digital converter 14.

Upon receiving the voice data, the reception control unit 15 determines in step 114 that there is voice input, moves to the step of the voice recognition comparing means indicated by the frame 115 of the virtual line, and proceeds to step 116. In step 116, the input voice data is temporarily stored and the process proceeds to the next step 117. In step 117, the sound in the voice data is analyzed, and in step 118, it is converted into a voice pattern, and this voice pattern is compared with the registered voice pattern registered in the storage unit 20 in step 119. If it is determined in step 119 that the two voice patterns match, the voice signal is considered to be the voice signal emitted by the transmitter 1 and the process proceeds to step 120. If the two do not match, the process returns to step 101. In step 120, the temporarily stored voice data is read out, compared with the registered voice word registered in the storage unit 20, and if it is determined that they match, in the next step 121, the voice data corresponds to this registered voice word. 22n after controlling the loads 22a, 22b, ..., 22n, and when it is determined that they do not match, the process returns to step 101.

On the other hand, when it is determined in step 114 that the voice data is not input, the process proceeds to the step of the direct control means indicated by the virtual line frame 122, and proceeds to step 123. In step 123, the operator operates the operation unit 16 of the receiver 2 and inputs the switch signals of the optional operation switches 16a, 16b, ..., 16n. Next, in step 124, the loads 22a, 22b, ..., 22n corresponding to the switch signals input in step 123 are controlled via the load control unit 21, and the process returns to step 101. Therefore, the desired loads 22a, 22b, ..., 22n can be directly controlled by the operation unit 16 of the receiver 2.

As described above, the loads 22a, 22b, ..., 22n can be controlled by transmitting the audio signal from the transmitter 1 and operating the operation unit 16 of the receiver 2. .. 22n can be controlled without using the transmitter 1 by emitting a voice that matches the registration data registered in the storage unit 20. Further, 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 embodiment, the registered voice data registered in the storage unit 20 of the receiver 2 is not limited to the method of inputting with the microphone 11, but may be registered in advance in another device, for example. It may be registered by voice synthesis. The voice data used by the transmitter 1 may be stored in the data reader 4 as long as the voice recognition comparing means 115 in the reception control unit 15 of the receiver 2 can compare the registered voice data with voice recognition. The method of reading from the medium 6 is not limited.
