本次论文是以一般电梯为例，不考虑其型号外观品牌等，也不考虑电梯的其他控制程序诸如开关门，停启动问题。就单纯地考虑电梯的群控算法与PLC编程。即在大于等于2部电梯的情况下，当有外部请求时，讨论电梯的调度问题。46562
在工业产品控制中，采用PLC编程技术是很好的选择。因为其有高可靠性，可编程性，丰富的IO接口模块，采用模块化结构可以适应各种工业控制的要求，安装简单维修方便等优点。在电梯群控中通过编程仿真来达到智能化的要求。
电梯群控算法有很多，如多目标规划电梯群控算法，基于统计近似的电梯群控算法等等。根据实际考察办公楼的性质确定最佳方法。当候梯者在等候电梯，乘坐电梯，到达目的层的整个过程中，等候电梯时间的把握很重要，要优先考虑。
选择合适的通信硬件和协议，是将电梯与控制设备联系在一起的最基础重要的关卡。西门子设备中通信协议有很多，如PPI通信协议，MPI通信协议，PROFIBUS通信协议，自由通信协议等。其中PROFIBUS是本次论文所采用的一种协议，最大特点在于具有稳定的国际标准EN50170作保证，并经实际应用验证具有普遍性。

ABSTRACT In modern science and technology developed, the era of intelligent buildings, the requirements of intelligent products also will be improved. The level of intelligent elevator is also improved, the purpose is to save the waiting time of the candidates.
This paper is general elevator, for example, regardless of the types of the appearance of brand and so on, other do not take into account the elevator control procedures such as opening and closing doors and stop start problem. Simply consider elevator group control algorithm and PLC programming. Is greater than or equal to 2 lifts, when external requests to discuss elevator scheduling problem.
In the control of industrial products, the PLC programming technology is a good choice. Because of its high reliability, programming, rich IO interface module, the modular structure can be adapted to various industrial control requirements, simple installation and maintenance is convenient wait for an advantage. In the elevator group control through simulation programming to achieve the requirements of intellgent.
Elevator group control algorithm has a lot of, such as multi-objective elevator group control algorithm, based on statistical approximation of the elevator group control algorithm, and so on. According to the actual investigation office properties in determining the best method. When the people who is waiting for the elevator waiting for the elevator, take the elevator, reach the purpose for the whole process, when the elevator time it is important to grasp to give priority to.
Choose the appropriate communication hardware and protocol, is the elevator and control equipment associated with the most basic important levels，Communication protocol of Siemens equipment there are many, such as the PPI communication protocol, the MPI communication protocol, communication protocol of PROFIBUS, free communication protocol. The Profibus is used in this paper is a kind of agreement, the biggest characteristic is with stable international standard 50170 as a guarantee, and the practical application of verification is universal.
Key words:Elevator group control; PLC programming; communication
