Research On Checking System Of Broken Safe_line Mechanical Engineering

This paper deals with the design and development of the checking system of broken safejine, which is very important in the checking of laying situation of this technics.This system is made of Programmable Logical Controller and other assistant device. For the reliability of the system, many mature techniques are adopted in the development of this system. On the choice of sensor, we choose a kind of near sensors, E2K-F10MC1, succeed in signal acquisition of forepart. On programming we adopt the way of circular counting and identify working situation of linejaying, in the same way, with the dynamic setting of circular periods and counting number the system has flexible and can meet the special requirement of acceleration. On the interface of human_machine, we adopt a kind of programmable terminal-MPT002, with this device we can set the circular periods, count number, start dropping and end dropping lay time.According to the special requirement of checking system of broken safejine , this paper primarily deals with how to choose sensor and modules of PLC as well as how to design the software of PLC, demonstrats the feasibility of the system in theory, expounds the development idea and method of PLC software.
