Diseño y simulación del movimiento gantry de una grúa portuaria STS mediante PLC y HMI

Abstract

In this graduation work, the gantry movement of an STS port crane is designed and simulated using PLC and HMI, which is a system in which the gantry movement is projected and controlled by means of a control system, it also studies the problems when the crane starts the disembarkation process in the port. The execution times of the gantry movement presents delays in the operating conditions of the crane and needs human intervention, that is why the use of an adequate control for the movement requires that the programming is able to regulate the speed according to the weight that has the crane, thus allowing the engine in working conditions does not present effort or failures in the engine during the execution of the movement. The use of an incremental encoder, as part of the motion control, offers an innovative improvement that significantly solves the problem of this process. The development of the system to control the movement will be carried out in several stages, including a phase of bibliographic research and the realization of initial simulation tests. The configuration of the incremental encoder together with the frequency inverter allows to evaluate the final behavior of the simulated system. The stages to be developed go from programming in TIA Portal to the simulation of the gantry movement of the crane obtaining a detailed view of how control and monitoring systems can be integrated to improve processes and ensure efficiency in port environments.
