    Combination prosecutor system for gas pipe
    [1] The present invention relates to a gas pipe adsorption unit inspection apparatus, and in detail, it is possible to inspect the airtight state of the fused gas pipe after the city gas pipe fusion, the three-dimensional simulation that the user can easily recognize the gas tight state of the gas pipe Have a purpose to provide
    [2] Natural gas is a clean fuel that contains little impurities such as dust and sulfur. It is an optimal energy that contributes to the preservation of the environment around large cities. It is lighter than air and easily diffuses into the atmosphere even when it is leaked. It is a low cost, safer, and more thermally efficient alternative to LNG, a domestic fuel, and is the preferred fuel.
    [3] This natural gas has a very high economic efficiency, especially when used for cooling and heating of large buildings, and is also supplied to the underground pipes in the installation, so as not only to solve traffic difficulties due to the transportation of fuel, but also to burn without installing a separate storage facility. Since it is a very useful fuel that is supplied up to the apparatus, the supply pipe is installed to supply a large amount of fuel, which is used to connect the supply pipe when the supply pipe produced in a limited length is extended to the length required by the user. The method uses fusion using a fusion machine.
    [4] When welding the polyethylene pipe for gas as described above, the most important thing in the construction of the connecting pipe is the inspection of the welded portion according to the construction and construction of the welded joint, the installer and the user to the inspection and supply pipe The weld should be examined in an objective and validated manner.
    [5] The inspection of the welded part used in the prior art is an X-ray inspection, which is very dangerous and the inconvenience of having to inspect the supply pipe constructed by the manager along with it, the ultrasonic method called Ultranic By using, the airtight test for the welded part, but the equipment used is expensive, the user can not easily purchase and use, there is a problem that can not be used for the actual inspection, and the above ultrasonic test equipment is used by the user The results provide a significant difference depending on the method, which makes it very difficult to check the weld state of the welded portion.
    [6] In addition, in the prior art, the medium of the polyethylene pipe may be different according to the production plant of the polyethylene pipe for gas. There was a problem that does not have reliability.
    [7] In view of the above problems, the present invention prevents the malfunction of the welded portion due to the change of the polyethylene material for gas in advance by learning neural networks using ultrasonic sensors, and fusion through accurate and reliable inspection. It is a tester that has a color display and a printing function for printing to show a part, and it is possible to record the state of the welded part to be provided to provide an objective and reliable test result to the user. Same as
    [8] The present invention transmits the ultrasonic pulse received on the flaw detector to the computer and digitalizes again, detects the feature of the pattern of the digitized pulse, controls the position movement of the transducer along the free curve of the specimen, the size of the defect of the specimen, and visually As illustrated, the detailed configuration is as follows.
    [9] Sensor fixed to pipe guideline to detect discontinuities present on or inside the material, Ultrasonic flaw detection unit (PULSER / RECEIVER) using C-SACN for nondestructive testing of materials by transferring ultrasonic waves to the material Hardware configuration to perform the function, A / D conversion board (10 ~ 500MHZ), IBM compatible COMP with built-in software package, Visual graphics program consisting of 3D SIMULATION and IMAGE PROCESSING to visually display the inspected contents It consists of a report that outputs the inspected content.
    [10] The C-SCAN configuration is based on the time axis of the A-SCAN which represents a waveform (a pure waveform before processing) that rectifies the RE waveform received on the flaw detector and then OVERLAPs the absolute value. After the explanation, it is composed of the LEVEL value of Peak beyond the threshold.
    [11] In the use of the present invention, while the sense is fixed in the pipe, the programmed transducer is moved up, down, left, and right, and the SCAN is executed. The task is to create a map, which can be learned by the sensor in the program, and the choice of color is an example of a lookup table by setting a numbered lookup table.
    [12] This consistent color value is preferably formed in steps from high values to low dimensions, and the color formed can indicate the distribution of discontinuities placed inside the inspection object. The state of the object to be inspected can be explored using a software package for three-dimensional simulation using hardware, and the test result can be output to a print having a REPORT function.
    [13] In addition, the sensor of the invention is to solve the problem that the difference occurs when inspecting the object in the same position according to the user's method of use, the pipe used by the program of the neural network in advance (polyethylene pipe for gas) It is preferable to use the CMS (Control of Monitoring System), which is a virtual measurement type, because the line is inspected and the welded portion is inspected while the pipe medium is known.
    [14] The present invention as described in detail above is a neural network using an ultrasonic sensor, the welded portion according to the change of the material of the gaseous polyethylene pipe by inspecting the welded portion after learning the material state of the polyethylene pipe for gas in advance It has the effect of blocking the malfunction of the camera in advance, displaying the color to show the accurate and reliable fusion, and having the printer function to record the status of the result.
