基于PLC 步进电机的自动门控制系统设计 I 基于PLC 步进电机控制自动门系统的设计 The Design Of Step Motor Automatic Door Control System 基于PLC 步进电机的自动门控制系统设计 II 基于PLC 步进电机控制自动门系统的设计 [摘 要]本文主要通过对自动门控制系统的功能要求和运行过程的分析，确定 了自动门控制系统的总体设计方案。自动门系统的设计主要集中在硬件和软件设 计两部分。并主要进行了自动门控制驱动和控制系统的设计。针对自动门控制系 统的特点和设计要求，采用步进电机驱动方式，通过四相八拍步进电机来精确控 制自动门的开关，给设计要求创造了条件。在控制部分，应用步进电机和可编程 序控制器技术，对自动门控制系统进行了硬件和软件设计。实现了自动门控制系 统的传动和控制要求，满足了环保、高效、可靠和低成本的要求。 [关键词]步进电机；??菱可编程序逻辑控制器；自动门；超声波开关； The Design Of Step Motor Automatic Door Control System Electrical Engineering and Automation Specialty FENG Jia－ying Abstract: This paper through the automatic control system and the working process of the functional requirements of analysis, the automatic control system of the overall design scheme. Automatic system is mainly focused on the design of hardware and software design. The automatic control and main drive and control system design. Automatic control system for the characteristics and design requirements, adopting step-motor drive mode, through the fourth phase eight clap stepper motor to precise control of the automatic switch, create conditions for design requirements. In control, application of stepping motor and programmable controller to automatic PLC control system, the hardware and software design. Automatic control system is achieved the transmission and control requirements are met, and the environmental protection, efficient, reliable and low cost.
