Mobile total quality management system that minimizes process delay and defect of test and inspection and improves reliability, and method thereof

The present invention relates to a mobile total quality management system that minimizes process delays and defects in test and inspection, and improves reliability. More specifically, the present invention relates to materials that are processed and constructed by different people at different places during plant construction. The present invention relates to a system and method for minimizing man power and human error that occur during computerization, while allowing test records and inspection records to be checked continuously and intermittently during the process by linking processes with subsequent processes.

In general, a plant refers to an industrial facility that manufactures and installs a number of machines and devices, such as power plants, petrochemicals, storage facilities, and refineries, to produce the desired results. The design will be completed, and the necessary materials will be procured and construction will take place over the years. For reference, these plant facilities have been developed around petrochemical and refinery facilities. In particular, the plant facilities are large and huge, and have been complicated and built over a long time as various equipments and machines are concentrated.

Therefore, in order to construct a plant facility as described above, it is necessary to obtain a large amount of piping or materials and machines / devices, and to manage storage and tracking of storage location in the material warehouse. After processing according to the specification and design instructions, the construction should be made according to the design drawing.

At this time, each worker is not only different people, but the materials are processed to the desired size and shape through various workshops, where quality control technicians (hereinafter referred to as management engineers) are referred to as their respective workshops. Visitors will inspect the client's specifications to verify that the material or equipment is being manufactured and installed, and that the materials or equipment are in good condition.

In other words, the pipe splicing process is simply provided with, for example, a plurality of pipes are procured, cut or extended by welding, and post-heated, and then the machined pipes are constructed according to the design drawings. Not only are they different from each other, but the workplaces are also different, so quality control technicians will not check their materials for abnormality and traceability whenever the process changes or transfers to another workplace.

Later, when the construction is different, the size may be different, or even if the construction is possible, it may be a problem later (pressure, temperature, etc.), so that quality control engineers test and inspect between each preceding and subsequent process. Records should be prepared and computerized and stored.

In this case, however, when the technicians prepare the inspection report, the test can be conducted only after the workers have completed the work. Therefore, the report is prepared in the late afternoon or evening time.

In particular, when bringing it back to the office to perform computerization work, it is already late at night or most of the time of dawn, so all must be tired.

Therefore, even when computerized, computerizing test and inspection records in a tired state at the late dawn time, frequent typos and inaccurate information input are inevitable.

Moreover, when such large plant work is performed, different people are divided into different parts of the working environment during the processing or construction of raw materials, and the management engineer is in progress after the preceding process is completed. There was also a problem that the on-site work was not performed smoothly due to the waiting time for testing the restraint.

Therefore, in the present invention, when the plant construction proceeds in conjunction with the preceding and subsequent processes by different people in different places. It aims to ensure that inspection records that are continuously checked in the middle can be smoothly and without delay, while minimizing the occurrence of man power and human errors when computerizing them.
