Positioning control system based on PC member stacker and method thereof

Abstract

The invention discloses a positioning control system based on a PC member stacker and a method thereof. The control system is composed of an industrial computer, a PLC, a rotary encoder, a proximity transducer, frequency converters, three-phase alternating current asynchronous motors and switching value equipment. According to the system and method thereof, on the premise that the travelling positioning precision of the PC member stacker is guaranteed, the using amount of the proximity transducer is reduced by ingeniously arranging the positions of iron columns and the proximity transducer; during lifting motion positioning, the rotary encoder is ingeniously utilized, the using amount of the transducer is reduced, and the lifting positioning performance of the PC member stacker is improved; the PLC is used for performing communication operation on the frequency converters in a PROFINET network communication mode, and the stability and reliability of the control system are improved; andthe upper computer performs overall monitoring on the control system, visualization of the control system is achieved, and the safety of the control system is improved.

Description

Technical field [0001] The invention relates to a positioning control system and method of a stacker, in particular to a positioning control system and method based on a PC component stacker. Background technique [0002] With the provisions of the "Industrial Building Evaluation Standards" officially implemented on January 1, 2016 (the prefabrication rate of participating projects should not be less than 20%, and the assembly rate should not be less than 50%.), my country's construction production mode has been changed from "building "To the "assembly" approach. The PC component stacker is an important module of the precast concrete component production line, and its electrical automation transformation is particularly important. Those skilled in the art are well aware that the core control of the PC component stacker is the positioning control, and the current PC component stacker's walking motion and lifting motion positioning control is mostly performed by arranging proximity...

AI Technical Summary

Problems solved by technology

Those skilled in the art know well that the core control of the PC component stacker is positioning control, and the current control of the PC component stacker’s walking motion and lifting motion positioning is mostly achieved by arranging proximity sensors at the positioning points. However, this method not only requires a large number of proximity sensors and high cost, but also increases the error rate and failure rate of the control system

[0003] At the same time, most of the existing PC component stacker automation control systems currently use a control method of direct connection of switching or analog quantities, which not only has poor anti-interference ability and poor stability, but also cannot be realized or can not be better realized.
