    • PURPOSE: An ultrasonic generating method and device are provided, which can be applied to different types of objects such as a flat board and a bent pipe by employing a high frequency ultrasonic sensor having a relatively small size. CONSTITUTION: An ultrasonic generating device comprises a target structure(10), a first ultrasonic generator(110), and a second ultrasonic generator(120). The first ultrasonic generator generates ultrasonic wave of a first frequency on the target structure. The second ultrasonic generator generates ultrasonic wave of a second frequency similar to the first ultrasonic wave on the target structure. The difference between the first frequency and the second frequency is extracted through beat phenomenon to measure the property of the target structure.
    • 目的:提供一种超声波发生方法和装置,其可以通过采用具有相对较小尺寸的高频超声波传感器应用于不同类型的物体,例如平板和弯管。 构成:超声波产生装置包括目标结构(10),第一超声波发生器(110)和第二超声波发生器(120)。 第一超声波发生器在目标结构上产生第一频率的超声波。 第二超声波发生器产生与目标结构上的第一超声波类似的第二频率的超声波。 通过拍子现象提取第一频率和第二频率之间的差异,以测量目标结构的性质。

    • PURPOSE: A method and a system for detecting leakage by using a camera image are provided to help a user to easily find out a leakage position which is not easily visually distinguished through camera image. CONSTITUTION: In a method and a system for detecting leakage by using a camera image, an image collection unit(100) obtains the image signal of an object in which high temperature and pressure is generated. An edge detection unit(200) detects an image signal edge before and after leakage generation. A comparison unit(300) detects only leakage image edge by obtaining the difference of an image signal edge before and after. A display unit(500) is connected to the comparison unit and displays the leakage image signal.
    • 目的:提供一种通过使用摄像机图像检测泄漏的方法和系统,以帮助用户轻松找出通过摄像机图像不容易视觉辨别的泄漏位置。 构成:在通过使用摄像机图像检测泄漏的方法和系统中,图像采集单元(100)获得产生高温和高压的物体的图像信号。 边缘检测单元(200)检测在产生泄漏之前和之后的图像信号边缘。 比较单元(300)通过获得前后的图像信号边缘的差异来仅检测泄漏图像边缘。 显示单元(500)连接到比较单元并显示泄漏图像信号。
