基于呼叫识别与屏蔽的电梯群控策略

Elevator Group Control Strategy Based on Call Recognition and Shielding

为了提高电梯群控系统综合性能,降低高层电梯群控系统的控制难度,提出了高层电梯群控系统的一种基于楼层呼叫识别与屏蔽的控制策略,建立了以层为基础的电梯运行数学模型,动态识别出电梯的各种呼叫状态,在特定情况下,对部分呼叫进行屏蔽,用虚拟的呼叫作为呼叫识别的参数,处理各类特殊要求的电梯群控,如直接响应模式、满员响应模式、短程快速响应模式、高峰快线调度模式及其他特殊控制要求,通过对虚拟呼叫的简单运算处理,很容易将这些特殊的控制模式融合到一个综合的电梯控制系统中,大大提高电梯群控系统的性能。

In order to enhance the synthesis performance of an elevator group control system and reduce the high-level elevator group control system＇s control difficulty, a group control strategy of high-level elevator con- trol system was proposed,which is based on call recognition and shielding. A dynamic mathematical model in terms of marked stories of the elevator group control system was established, which can identify the various status of the elevators. In certain circumstances, shielded some call signs and identified some calls with the vir- tual signs, the various special requirements of elevator group control system could be handled. A direct re- sponse mode, a full load response mode, a short-range rapid response mode, a peak express scheduling mode and other special control requirements were mentioned. By simple operation processing to the virtual call signs, these special control modes can be merged into an integrated elevator control system easily. In this mode, the performance of elevator group control system is advanced greatly.
