The invention provides a control method of an intelligent tension
system and the intelligent tension
system. The method is characterized by including the steps that a loading speed
control unit is built and used for detecting pressure of an oil inlet, and the pressure, monitored in real time, of the oil inlet is compared with preset pretightening force of each stage; a prestressing
tendon extending amount
control unit is built and used for detecting the displacement value of a prestressed
steel bar in real time in the tensioning process and the displacement value of the prestressed
steel bar in set holdup time after the prestressed
steel bar reaches set tension force of each stage; tensioning values of different jacks are compared after first-stage tension; control signals of different stage conditions in the tensioning process are converted into electromagnetic motions and frequency converter rotation speed control requirements; according to signals fed back by a
pressure sensor and a displacement sensor in the tensioning process, the related control commands undergo fuzzy conditioning. The control method and the
system have the advantages of improving data measuring precision and construction efficiency, reducing labor intensity of construction workers, reducing cost, improving labor efficiency, eliminating safety hidden risks of the construction workers, and enabling the whole tensioning process to be finished at a time.
