System Design Of Container Crane Training Simulator Instructor Taiwan

Port crane is the main load and unload equipment in port, how good the manipulator's skill is the key factor in determine the safety, efficiency , durable and profit of using the equipment. Compared with train in real equipment, train simulator has obvious advantageous in economical and safety, So , it is of great realism sense to developing port crane train simulator.This paper describe part of work in the project "train simulator of container crane", Including the design of teacher worktable and the realize of some of it's function. Teacher worktable control system including main computer, instruct screen, scene watch screen, driver chamber monitor and relative input output equipment. Main computer is the control center of the whole teacher worktable system. The main function of the system include self check; parameters set; train condition set; selection the type of container and relative equipments; system control and monitor of the simulator process; record and replay of the train process; automate evaluating and mistake analysis. Teacher worktable system was designed with modularized method and the main part was written with VB.Container movement track optimization and the automate evaluating of student's action are two important function of the teacher worktable. Comparing the moving track of container with the optimized moving track of container generated automatic as a way of judge the operation of student. It is a feature of this project. It is difficult to solve the container movement track optimization problem by using general method to solve optimization problem such as minimum value method and dynamic plan. This can be seen clearly through mathematic analysis. After Simply this problem, make elementary fold line according to the start point, the end point and the hinder point between them. Not consider the sway when student are operating and just search for optimal track in the fold lines which through start point and end point and cover the hinder point. For the sake of.realize speed change between two linked part of a fold line. Using grind function to process the fold lines to change it into realizable moving track.In realize the automate evaluating of student's operation, judging the operation in four ways: the step of operation; the quality of operation; the dispose in failure and the impression of teacher, the impression of teacher was input by teacher through teacher worktable. The step evaluate program read the state of equipment every other thirty millisecond to track the student's operation. The step evaluate program realize evaluate by using some rule based on operation formula. The quality evaluate program works according to operation efficiency and speed of collision. The dispose in failure evaluating program evaluate how good the student process failure when teacher set failure in teacher worktable. The teacher's impression evaluating was set by teacher in teacher worktable. Using Fuzzy method to obtain the integration evaluating. First fuzzy the evaluating obtained in different ways to get the matrix of fuzzy collection and then get the fuzzy rule according to knowledge and experience. Using maximum-minimum rule to integrate the matrix of fuzzy rule and the matrix of fuzzy input to obtain the fuzzy output. Defuzzy the output If points is needed. Using fuzzy method can formalize and modelize the experience of people and change it into model that can be processed by computer. This kind of method can reflect the reality better than average method with weight for it can simulate the experience of people.
