The Research Of Technique Of Elevator Group Control

In modern intelligent buildings, people always equip for a building several elevators because of all kinds of demand of passengers and big flux of passengers. That can improve service quality and service efficiency of system of elevators. It makes the building work well. The technique of group control of elevator is suitable for realization the above object.What the group control of elevators traffic system deals with is a complex, random, multi-object, decision-making problem with much non-linear and uncertainty. Based on summarizing some domestic and overseas research achievements of elevator group control system, in this paper, author analysed the property of elevator traffic system and setup a model of elevator group control. Also traffic situation of elevator group control is analysed, using 'the nearest distance and minimum waiting time etc'. parallel connection dispatching control pinciple, the paper designed a simulation of elevator group control system. The paper is described simply as following:Chapter 1 begins with introduction of the relative papers published in domestic and overseas. Then the importance of researching is described. At last the purpose and content of research are put forward.In chapter 2 author analyses the characteristic of elevator group control system. Then the dispatching principle of group elevators is described. Finally general control methods of group elevators are introduced in detail.Chapter 3 describes traffic pattern identifying of elevator group control system and the setup of the math module of the group elevators. Furthermore algorithm of group control system are introduced in detail.Chapter 4 introduces general problems of system simulation and several simulations of elevator group control. The paper also had been on application reserch of the above problems.Chapter 5 analyses the design of hardware of the system of group control. The parts of hardware system and their working principles are described. Also circuit of interface of the system is described.Chapter 6 tells us the keys of software design in papers. The diagram of each software module is introduced at length. At last measures dealing with electric disturbing are illuminated in papers.Chapter 7 sums up and prospects the research simply.
