Description

SOUND SOURCE DETECTION APPARATUS The present invention relates to a sound source detection device. Various high-pressure process gases are used in the manufacturing processes of semiconductor or display devices. Since these process gases are toxic and hazardous chemicals that can cause casualties and environmental pollution upon leakage, equipment for detecting leaked gases is installed and used at industrial sites. However, these systems are unable to respond quickly to chemical leakage accidents because they take a long time to detect leaks and it is difficult to locate the source of the leak. Figure 1 shows the configuration of a sound source detection device according to one embodiment of the present invention. Figure 2 shows the configuration of a sound wave detection unit according to one embodiment of the present invention. FIG. 3 is a diagram illustrating a sound source detection method using a sound source detection device according to an embodiment of the present invention. FIG. 4 is a diagram illustrating a sound source detection method using a sound source detection device according to another embodiment of the present invention. The present invention will be described in detail below through examples. The purpose, features, and advantages of the present invention will be easily understood through the following examples. The present invention is not limited to the examples described herein and may be embodied in other forms. The examples introduced herein are provided to ensure that the disclosed content is thorough and complete, and to ensure that the concept of the present invention is sufficiently conveyed to those skilled in the art to which the present invention pertains. Accordingly, the present invention should not be limited by the following examples. Although terms such as "first," "second," etc., have been used in this specification to describe various elements, said elements should not be limited by such terms. These terms are used merely to distinguish said elements from one another. FIG. 1 shows the configuration of a sound source detection device according to one embodiment of the present invention, and FIG. 2 shows the configuration of a sound wave detection unit according to one embodiment of the present invention. Referring to FIGS. 1 and 2, the sound source detection device (100) may include a sound wave detection unit (110), a sound source location determination unit (120), a sound source location shooting unit (130), a display unit (140), and a control unit (160). The sound wave detection unit (110) can detect sound waves or ultrasonic waves formed by a sound source to generate sound wave detection information, and can provide the generated sound wave detection information to the sound source location determination unit (120) and the control unit (160). The sound wave detection unit (110) includes a plurality of sound wave detectors (111), and each of the plurality of sound wave detectors (111) can detect sound waves or ultrasonic waves to generate sound wave detection information, and can provide the generated sound wave detection information to the sound source location determination unit (120) and the control unit (160). The sound wave detection information may include a sound wave detection signal and the intensity of the sound. The sound wave detector (111) may be a microphone or a device including a microphone. For example, the sound wave detection unit (110) may include 112 microphones. A plurality of sound wave detectors (111) may be integrated and arranged within a single device, or they may be spaced apart from each other within an area for detecting sound sources. Multiple sound wave detectors (111) can accurately detect sound waves or ultrasonic waves while reducing the influence of noise. For example, when chemical gas leaks from industrial process equipment, a leak sound source is generated at the source of the leak, and the sound waves or ultrasonic waves formed by the leak sound source reach each of the multiple sound wave detectors (111). Since the distance from each of the multiple sound wave detectors (111) to the leak sound source is different, the time taken for the multiple sound wave detectors (111) to detect the sound waves is different. If Vs is the speed of sound, the time it takes for a sound wave or ultrasound formed by a leaking sound source to reach a sound detector (sound detection time) is the value obtained by dividing the distance (S) between the leaking sound source and the sound detector by Vs (S/Vs). (Illegible) The speed of sound is 340 m/s at 1 atmosphere and 15°C, and since the speed of sound increases by 0.6 m/s for every 1°C increase in temperature, the speed of sound can be determined and the sound wave detection time can be calculated by referring to the temperature at the location where the industrial process equipment and the sound source detection device are placed. For example, when the temperature at the location where th
