The Development Of The Optical Fiber Preparation Collapsar PLC Fuzzy Control System

The optical fiber preparation collapsar PLC control system is a set of equipment that be using at the scene by YOFC. The P8 system of PHYLIPAS CO.. is used on the system.. Long time,Because of keeping secret of technology,the development kit of the P8 system and the original program did not be provided,So YOFO proposed to cooperate with Wu Han university of technology,and based on productive practice,to absorb these advanced techniques,to know the system and design an applicable collaperser machine control system.The paper describes the work as follows.First,based on the knowledge of collapsar technics,this paper analyzes the characteristic of optical fiber collaperser machine software system and hardware structure,A P8 system and it's development kit has been installed first in China,and the hardware system of the optical fiber preparation collapsar has been designed and debugged.Considering many control qualities,such as,the control reliability and accuracy,the level automation ,etc,the whole control system is constituted as following :CRT interface of man-machine conversation (with CPU),keyboard,PLC control system,motor driving machine,protection board,and relative control circuit.The p8 system is used in PLC control system .It has high level of automation and applicable particularity for its opening structure and reasonable and clear network. Data sampling,process,control and man-machine conversation,control function which are communicated by connecting its communication module and CRT.Secondly,according to collapsar technic,with the help of PDS7,the software for Automatic collapse,initiation task,trouble task has been programmed and debugged on the P8 system. The special task was separated from the main recycling task in software designing,all of these make the design simple and improve the system speed. This software has perfect performance that present the design,programming and debugging function. SFC was used in the main recycling task,The IL and ST language was used in the special task.Finally,the Fuzzy control theories has been applied to the P8 system for control the pressure difference of gas side and pump side. The control system has been simulated. Simulation test show that the Fuzzy control system achieves desirable precision.The research and development of the optical fiber preparation collapsar PLC control system has the important significance for realizing PLC control system made in our country early and improving the quality of the optical fiber preparation.
