Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel bar processing for house building engineering, and particularly relates to a modular intelligent steel bar processing production line and process based on Internet of Things. BACKGROUND

[0002] As one of the three main materials of civil engineering, the cost of steel bar accounts for more than 30% of the total cost of the project. At the same time, as the main load-bearing unit of the engineering structure, the construction quality of the steel bar is related to the safety of the structure, and plays an extremely important role in building construction. At present, building main materials such as steel structure, formwork and concrete have realized factory processing and commercial distribution, but only steel bars are still mainly processed on site. The traditional steel bar processing method not only needs many laborers and has high labor intensity, but also has many problems such as high raw material loss rate, poor environment, difficult management and the like.

[0003] In recent years, there are many application explorations of steel bar centralized processing and distribution in the industry, but in the field of house building construction, they have not achieved the expected effect. The main reason is that the differences in the type, specification, size and quantity of steel bars for house building engineering are large, which is not suitable for traditional industrialized batch processing, and the length and weight of steel bar raw materials and semi-finished products are large, the transportation cost is high, the on-site inspection and quality traceability are difficult, and the emergency response is not timely due to the lack of processing equipment on site, which seriously affects the construction progress.

[0004] At the same time, the existing steel bar processing equipment in the field of house building engineering has low automation level, poor collaboration, is heavy and not easy to transport, and the informationization empowerment of steel bar processing management process is insufficient, which still needs manual allocation of processing tasks and input of processing parameters, and the quality of the formed steel bar cannot be accurately traced. In addition, steel bar processing data cannot be well collected, and past experience data cannot be well utilized and guide subsequent processing.

[0005] Therefore, to realize factory processing and commercial distribution of steel bars, it is the key to develop steel bar processing equipment and production line with high flexibility and economic practicability. SUMMARY
