Application of MODBUS Communication Protocol in Intelligent Prestress Tension Robot

The prefabricated concrete structure is conducive to the development of China’s building industrialization. It is one of the important directions for the development of China’s building structure, of which prestressed concrete structure is an important part of the prefabricated concrete structure. The key technology to achieve prestressed concrete is the tension of the prestressed steel strand. The tensioning process includes: 1 The prestressed steel strand penetrates the tension hole of the tensioning equipment. 2 the tensioning equipment continues to tension the prestressed steel strand. Among them, the perforation process of tension has always been manually realized. At present, industrial intelligence includes all walks of life, and equipment related to construction projects also conform to the development of intelligence. The intelligent tensioning robot proposed in this paper is based on the tensile equipment to add a robotic arm, sensors, etc., which can automatically find tensioning holes to facilitate the perforation process when the prestressed ribs are stretched, with the purpose of improving the efficiency of perforation, improving the safety of the tensioning process, and reducing the dependence of tensile construction on labor. In this article, the method of collecting anchor plate position information is introduced, and the modular program of MODBUS communication based on Delta PLC is provided.
