Analysis Of PLC Elevator Control System And Study On The Elevator Installation Project Management Optimization

With the rapid development of engineering technology such as automatic control, elevator has become a high-rise building complex electromechanical combination of special equipment.With, the continuous development of city construction, high-rise buildings, the elevator in the national economy and the growing demand in the life. But the use of the elevator also has a risk, in the event of accident economic loss and injuries is becoming more and more big. Because of its stability and simplicity, in recent years, the PLC is widely used in the elevator control.Through induction and analysis the elevator technology foundation and take advantages of PLC, this thesis designs the elevator control system based on PLC.According to the current installation project progress and problems existing in the quality and cost management, this thesis carries on the reasonable optimization and develop the elevator installation project management rules.The following is the specific research content and results.(1) In order to optimize the elevator control system, this paper systematically analyzes the relevant theoretical and technical basis of the elevator, the automatic control principle of PLC, and the development of PLC and its advantages in the application of elevator control.(2) Establish Elevator control system model, introduce PID controller, and draw PID controller system block diagram, carry out the design and Simulation of PID controller Combined with the elevator passengers use requirement, established the functions of the elevator PLC control system, draw up control circuit design steps of the PLC elevator system.(3) Through the research of elevator installation project management practice, analysis the problem of elevator installation schedule management quality management, as well as the cost management deeply, formulate the reasonable elevator installation countermeasures, expounds the PLC control elevator installation quality in engineering management and cost management problems and puts forward the relevant measures.(4) Summarize the practice situation of elevator installation engineering of the year, combined with Hitachi elevator shandong branch splendid city in the west railway station building elevator installation content all the way, work out the for Hitachi elevator in the building installation construction organization plan, formed the relevant elevator installation procedures.
