ABSTRACT
The design, modeling and simulation of CAD are designed and realized; Computer control is to replace the traditional control mode with computer as a control mode. Therefore, in the structure of the computer control system, in addition to the analysis of the relevant control principles, we should also learn from the relevant principles.
The main function of the program controller is to compile programs, modify programs, test programs, and upload qualified programs to PLC. The software mainly adopts PC, but must use the special software of Siemens. S7-200 PLC applies STEP7 Micro/WIN software, based on Windows; Three programming languages: ex pression table, ladder diagram, function box diagram; Its functions include: guidance and password protection; Slave protocol indication, internal USS protocol, PID regulator, etc; PC and PLC can use PPI line or CP communication board to complete communication and share programs; Support TD400C, TD400 and other common text interfaces. The work done in this paper includes: First, from the working mechanism of PLC control system, the overall structure of the elevator is designed; Secondly, according to the structure and requirements of the elevator, the hardware of the system is designed in detail; Finally, the overall design of the system and the related program design are realized.
