Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system and a method for guiding an important authority setting of a dangerous apparatus control apparatus using ambient sounds,

The present invention provides a method and apparatus for controlling a hazardous material equipment by controlling the control of the dangerous material equipment in direct contact with the dangerous material equipment, It is possible to control the dangerous materials equipments to be managed only by the naked eye while preventing the risk of the risk to the administrator as much as possible, The present invention relates to a system and a method for guiding an important authority setting of a dangerous group control device using a surrounding sound,

Generally, since it is important to manage the plating liquid level and the temperature at the time of plating, the plating apparatus for performing plating on the surface of a wafer, which is a semiconductor part, is provided with emergency buttons capable of controlling operations in the plating vessel for carrying out the process.

In this way, the manager can control the emergency button installed near the plating tank directly in case of an emergency, so that the control can be urgently controlled.

However, when the emergency control situation occurs in the plating processing apparatus, the manager moves directly to the vicinity of the plating tank and manually controls the control. Therefore, there is a problem that the manager has to carry out the work with the dangerous situation according to the manual operation.

In order to solve this problem, a general plating apparatus is proposed to control the plating liquid level and temperature at the time of plating by a computer.

On the other hand, since the control method of the plating processing apparatus based on the control of the conventional computer is a method that can be managed from a remote place, there is a problem that there is no way to monitor the plating control apparatus when the administrator manages poorly.

Further, there is a problem in that the control method of the plating processing apparatus based on the control of the conventional computer can not provide a method of recognizing the control through the hacking from the outside and guiding the control not to perform the control.

Such a problem is equally derived not only in the plating apparatus but also in a dangerous substance treating apparatus such as a metal smelting apparatus such as iron.

In addition, the control system based on Internet of Things (IoT) in various industrial fields which are currently in the spotlight is also derived.

By using the system for guiding the important authority setting of the dangerous group control device using the ambient sound of the present invention having the above configuration, it is possible to control the dangerous material equipment at a close distance from the dangerous material equipment The following is a description of the process of providing the management of hazardous equipment only to the naked eye, while preventing the risk to the administrator as much as possible.

First, the administrator sets the installation position of the critical-group control device 100 that performs the important permission setting (on-boarding) of the critical-group devices 1a, 1b, 1c in the device control area S, S100). The procedure is as follows.

The manager places the dangerous group control device 100 in the equipment control area S at a place where the dangerous group control device 100 is to be installed (S101).

The administrator selects a longest distance position E within a region corresponding to the longest distance from the dangerous control device 100 disposed at the control device installation place in the equipment control area S at step S102.

Then, the manager places the manager terminal 200 at the longest distance position E in the area of the equipment control area S (S103).

Thereafter, the administrator requests a test as to whether the sound is properly recorded in the state in which the risky device control application 201 of the administrator terminal 200 is running.

At this time, the dangerous control device 100 located at the control device installation place of the equipment control area S operates the microphone 130 to receive the sound of the audible band, which is the ambient sound generated at the place where the control device is installed, And transmits the device-side test audible band audio signal to the device management server 300 (S104).

The manager terminal 200 disposed at the longest distance position E in the area of the equipment control area S also operates the microphone 220 to measure the audible band sound And transmits the recorded test audio and visual audio signals to the device management server 300 (S105).

The device management server 300 analyzes the device-side test audible band audio signal and the terminal-side test audible band audio signal transmitted from the risk-based control device 100 and the administrator terminal 200, respectively, by operating the signal analysis engine 320 Then, it is confirmed whether both audio signals are identical (S106).

If the audio signals of the two devices are not the same, the device management server 300 increases the sensitivity of the device including the value of increasing the sensitivity of the microphone 130 of the corresponding dangerous control device 100 in the device management server 300 And sends the control signal to the corresponding critical-group control device 100 (S115).

Thereafter, the dangerous control device 100 receives the microphone sensitivity increase control signal and increases the sensitivity of the microphone 130 by the sensitivity value included in the transmitted microphone sensitivity increase control signal (S116).

Then, the high-risk group control device 100 operates the microphone 130 to receive the audio of the audible band, which is the ambient sound generated at the control device installation place, and transmits the recorded device-side test additional audible band audio signal to the device management server 300 (S117).

The manager terminal 200 disposed at the longest distance position E within the area of the equipment control area S also operates the microphone 220 to measure the audible band sound that is the ambient sound generated at the longest distance position E in the area And transmits the terminal-side test additional audio-band audio signal to the device management server 300 (S118).

Thereafter, the device management server 300 operates the signal analysis engine 320 to receive the device-side test additional audio-band audio signals and the terminal-side test additional audio and video data transmitted from the risk-based control device 100 and the administrator terminal 200, respectively Analyzes the audio signal, and repeatedly adjusts the sensitivity value of the microphone 130 of the dangerous-group control device 100 (S119) until both audio signals are the same.

Then, the signal analysis engine 320 of the device management server 300 registers the repeatedly adjusted sensitivity value in the vendor-specific risk group equipment list information DB 311 (S120).

On the other hand, the signal analysis engine 320 of the device management server 300 analyzes the device-side test audible band audio signal and the terminal-side test audible band audio signal respectively transmitted from the high-risk group control device 100 and the administrator terminal 200 1b and 1c installed in the equipment control area S in the process of checking whether the audio signals of the two audio signals are the same (S106) 1b, and 1c having a sound acquisition restriction radius S2, which is a radius when the distance in which the surround sound of the equipment control area S is obtained is limited, exists in the risk group equipment list information DB 311 (S107).

The device management server 300 determines whether there is a risk group equipment 1b having a sound acquisition restriction radius S2 around the risk group control device 100 among the risk group equipment 1a, 1b, 1c installed in the equipment control area S (S108) the rearrangement of the corresponding manager terminal 200 to the sound acquisition limiting radius S2, which is the limited distance with the risky control device 100 as the center. That is, if the terminal location relocation guide signal including the distance information of the sound acquisition restriction radius S2 is transmitted to the corresponding manager terminal 200, the risky device control application 201 of the manager terminal 200 transmits the terminal position relocation The distance information of the sound acquisition limit radius S2 included in the guide signal is output through the display unit 210 so that the manager can recognize it.

The device management server 300 transmits a microphone sensitivity reduction control signal including the sensitivity value of the microphone 130 of the corresponding dangerous control device 100 corresponding to the distance of the sound acquisition restriction radius S2 to the corresponding dangerous group control device 100) (S109).

The dangerous group control device 100 receives the microphone sensitivity reduction control signal and reduces the sensitivity of the microphone 130 by the sensitivity value included in the transmitted microphone sensitivity reduction control signal (S110).
