The invention relates to a method for controlling and optimizing opening and closing of a door based on DCS configuration logic. The method comprises the following steps of during the opening and closing of a full-open and full-close valve, outputting a stop command by a control module to control the valve to perform a pause valve opening operation; and in the DCS screen, displaying the current opening stroke state of the valve through the valve opening stroke bar, wherein a full bar indicates that the valve is fully open, an empty bar indicates that the valve is fully closed, and a valve in the middle position displays a progress bar at the corresponding position. The invention can be applied to the operation mode of random startup of high-pressure heaters, can effectively shorten the startup time, reduce the thermal shock of the heater and improve the efficiency of the unit. 本发明涉及一种基于DCS组态逻辑的开关门控制优化方法，包括：在全开全关阀门执行开关动作过程中，通过控制模块输出中停指令，控制阀门执行暂停阀门开度动作；在DCS画面中，通过阀门开度行程条显示阀门当前的开度行程状态；其中，满条代表阀门全开，空条代表阀门全关，阀门在中间位则
