Abstract

PURPOSE:To prevent the malfunction of a controller by providing a voice controller for inputting voices information to a mobile station of radio equipment, and controlling the input level in response to the voice volume of a worker or the ambient noise level. CONSTITUTION:A worker speaks the prescribed information to a mike 33 after controlling the input level by an input voice volume controller 38. Then the voice of the worker is sent to a transmitter 31 via the controller 38 and converted into voltage signals. These signals are sent to a fixed station 20 for radio equipment in the form of rado waves through an antenna 34. The processing result obtained at the station 20 is delivered through a voice output device 13 and received by a mobile station 30 to be transmitted to the worker through a speaker 35. In this case, the voice input level is set at a high value together with increase of sensitivity in case the sound level is low at the periphery where the voices are inputted. As a result, the worker can feed the voice information at a low level. Thus it is possible to feed assuredly the voice information regardless of the level of the peripheral noise.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention is directed to a system installed in a place where an IC is installed.
If is activated by human voice via wireless radio waves.
The present invention relates to a voice information input device.

[Background of the invention]

In recent years, voice information input devices that operate the control device ``L'' using the worker's voice have become widespread. It is common for workers to be able to input voice information to a control device via radio waves using a radio mobile station carried by the worker.And,
Gives work instructions to the worker via voice from the control device.
A voice information input device equipped with a so-called guidance mechanism.

In a voice information input device equipped with a so-called answer-back mechanism, in which the control device sends the information entered by the worker by voice to the worker by voice so that the worker can confirm the information, the worker can receive guidance or a voice that is returned. In order to make it easier to hear the sound, the volume of the signal received by the receiver can be adjusted using a volume controller installed in the receiver of the radio mobile station. However, since there is no need for the transmitter side of conventional radio mobile stations to directly hear the voice emitted by the worker,
There was no volume control. Therefore, the voice input level input to the voice recognition device of the control device is adjusted to be suitable for voice input by adjusting the voice of the receiver output (i) of the wireless fixed station that communicates with the wireless mobile station. For this reason, there was a problem in that the voice input level varied depending on the strength of the worker's voice, and the voice recognition rate decreased for people with weak voice. When the level of various noises such as noise, exhaust noise, rotation and sliding noise of various machines changes, the noise around the worker may be mistakenly recognized as voice input, causing control equipment to malfunction and reducing reliability. In particular, with voice information input devices equipped with a voice guidance mechanism and a voice answerback system, unnecessary guidance and answerbacks are sent to the worker through the speaker every time a malfunction occurs due to the above-mentioned noise, etc. This was annoying to workers and hindered safe work.Furthermore, each time a worker received incorrect guidance or answer back,
It was a hassle to have to make that one correction.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a voice information input device that can adjust the voice input level at a radio mobile station according to the voice volume of a worker and surrounding noise, and can prevent malfunctions.
