Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a voice control device that controls a plurality of mooring aircraft using multiple channels.

[Prior art]

In conventional mooring machines, as many remote control stands as there are mooring machines are placed on the side, and each stand has a speed control handle, a high/low speed gear changeover switch,
It is equipped with a drum clutch engagement/disengagement switch, a drum brake ON/OFF switch, etc., and normally an operator operates these handles and switches according to the command of the dispatcher, and moves the mooring aircraft according to the command.

The operation of these handles and switches is extremely complicated, and errors in switching the clutch sometimes occur due to operator error.

As described above, conventional remote controllers require an operator, and are the key to saving manpower and labor during mooring operations.

As a solution to these problems, a patent application was made in 1983 for the dispatcher to directly control the mooring aircraft by voice.
No. 158245 “Voice control device for mooring aircraft”
is proposed.

[Problems to be solved by this invention]

This invention relates to an improved invention based on the above-mentioned application. For example, a single voice recognition device can perform multiple processing on multiple groups of mooring machines installed on the stern and bow sides and operated by each person in charge. The present invention provides a multi-channel voice control device for a mooring machine, which enables a control device on a ship to be configured compactly and economically.

[Structure of the invention]

The multi-channel voice control device for a mooring aircraft according to the present invention includes a voice command transmitter to which different frequency channels are assigned to each of a plurality of commanders, and receives voice command signals from these transmitters and uses them as voice signals. a receiver that outputs an identification code for each frequency channel; a voice recognition device in which a voice pattern for each commander is registered in advance and that recognizes a command word by inputting the identification code and voice signal from the receiver; Furthermore, it is characterized by comprising a control section that controls a specific mooring machine based on the recognition result from the voice recognition device and the identification result from the receiver.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained below with reference to illustrated embodiments.

The attached drawing shows a case in which the bow section commander 1b uses channel B and the stern section commander 1a uses channel A to control mooring machines 9a and 9b in two groups, stern section and bow section, by voice. It shows.

The stern dispatcher 1a and the bow dispatcher 1b each carry transceivers 3a, 3b and head sets 2a, 2b for dispatchers, and transmit predetermined command words on the frequencies of voice command channels A and B. It is possible.

Furthermore, in this device, antennas 5a and 5b for channels A and B are attached to the bridge part of the ship, and when these antennas 5a and 5b receive radio waves from channels A and B, they emit RF signals 6a and 6b.
is output to the receiver 11.

This receiver 11 demodulates the RF signal and outputs an audio signal 12 and identification codes 13 for channels A and B. Connected to the output side of the receiver 11 is a voice recognition device 14 in which a voice pattern of a commanding person is registered in advance. This voice recognition device 14 receives the voice signal 12 from the receiver 11 and the channel identification code 1.
3, and after specifying either channel A or B using the channel identification code 13, the voice pattern of the dispatcher corresponding to the receiving channel is compared with the input voice signal 12, and the word with the most matching pattern is recognized as the recognition result. It is output as 15.

A control computer 16 is connected to the output side of the voice recognition device 14, which inputs the channel identification code 13 from the receiver 11 and the recognition result 15 from the voice recognition device 14, processes it, and processes it. An instruction code 17 is output to the speech synthesizer 18 so as to synthesize the recognition result 15. In addition, as an output of another system of the computer 16, each mooring machine 9a, 9
Control signal lines 7a and 7b are formed for outputting control signals to b.

The synthesized sound generated by the voice synthesizer 18 based on the command code 17 is output as response voice signals 8a, 8b to speakers 10a, 10b provided near each mooring machine 9a, 9b.

In this way, the speakers 10a, 10b output the recognition results to the commanders 1a, 1b in the form of synthesized sounds, thereby performing an answer back.

In the above configuration, in this voice control device, voice commands issued from the commanders 1a and 1b are inputted from the microphones of the headset 2a and 2b, and transmitted from the transceivers 3a and 3b to channels A and B.
is emitted as a radio wave. These radio waves 4a and 4b are received by antennas 5a and 5b and input to a receiver 11. In addition to the audio signal 12, the receiver 11 outputs an identification code 13 corresponding to the receiving channel. The speech recognition device 14 compares the speech patterns of the commanders 1a and 1b corresponding to the identification code 13 of the receiving channel with the speech signal 12, and outputs the word with the most matching pattern as the recognition result 15.

The control computer 16 generates a command code 1 for immediately synthesizing a response voice corresponding to the recognition result 15 from the channel identification code 13 and the voice recognition result 15.
7 is output to the speech synthesizer 18. Speech synthesizer 18
synthesizes the response audio signals 8a and 8b, and transmits the recognition results to the commanders 1a and 1b through speakers 10a and 10b.

The dispatchers 1a and 1b listen to the recognition results, and if they are correct, give a confirmation voice (for example, "OK" or "Okay"), and the channel identification code 13 and recognition result 15 are sent to the computer 16 using the same procedure as above. is input. The control computer 16 is
Similarly to the above, the command code 17 is output to the voice synthesizer 18, and a voice indicating that the confirmation voice has been recognized is output to the speakers 10a and 10b to the commanders 1a and 1b.
It can be conveyed from.

In addition, the control computer 16 identifies the mooring machine to be commanded from the channel identification code 13 and the recognition result 15, checks the current state of the mooring machine's clutch, brake, high-low speed switching gear, etc., and then changes them if necessary. It automatically outputs a switching signal, and also automatically outputs a rotation speed signal and a switching signal to auto tension.

In this way, one set of receiver 11, speech recognition device 14, computer 16 and speech synthesizer 18
The mooring machines 9a and 9b on the bow side and the stern side are voice-controlled. Even if these two systems of command input are issued at the same time, it can be handled without time delay by dividing the channels by filter processing in the receiver 11 and performing multiple processing using a time division method in the voice recognition device 14 and computer 16. .

Furthermore, by changing the voice pattern registration settings in the voice recognition device 14, the commander can be easily replaced or changed.

〔Effect of the invention〕

The embodiment of the multi-channel voice control device for a mooring aircraft according to the present invention is as described above, and the following effects can be achieved.

A multi-channel voice control device for a mooring machine is capable of multiplexing multiple groups of mooring machines with a single voice recognition device, and enables a compact and economical configuration of an onboard control device.
