摘要：通过单片机控制每一列车厢的车门的开关，通过一些单片机传感元器件检测车门的开启状态,检测车门运行时是否有发生异常情况，比如是否有异物堵住车门。单片机给出车门电机转动信号，此时驱动电机的正转与反转正是反应列车车门运行状态，同时通过位置传感器检测门的位置状况，从而决定电机的转动与停止，系统要求具有一些指示灯，显示门的开关状态，论文仿真采用STC89S52芯片作为主要控制芯片。考虑到要将单片机的电平信号放大，决定使用ULN2003芯片达到预想的功能，从而实现仿真列车的车门和屏蔽门的开启和关闭。使用操作按钮直接控制车门和屏蔽门的开启，并且在上方还设有指示灯、计时器、蜂鸣器提醒乘客的安全，主要控制目的就是要控制好车门的感应器，和计时器，当乘客离开车厢或者进入车厢，在感应区域内，都必须保证乘客的安全，所以对于感应器的要求是很高的，考虑到仿真的局限性，只能作出车门的开启和关闭以及一些指示灯的显示。42083

Design of the door control system of single-chip microcomputer
Abstract: through the single-chip microcomputer control of each column compartment door switch, through some SCM sensing components detection door opening state, door detect run-time whether abnormal conditions occur, such as whether there are foreign bodies blocked the door. SCM is given the door motor rotation signal, at this time of the drive motor is transferred and inversion is response running status of train doors and also through the position sensor to detect the door position, so as to determine the motor rotation and stop, system requirements, with some indicators that show the switch state of the door, the simulation using STC89S52 chip as the main control chip. Taking into account the level of the microcontroller to be amplified, the decision to use the ULN2003 chip to achieve the desired function, so as to achieve the simulation of the train door and screen door open and close. Use button operation directly control the opening of the door and screen door, and at the top is also provided with indicator, a timer, buzzer to remind passengers to safety, main control objective is to control door sensors, and timer, when the passenger compartment to leave or enter the compartment, in the sensing area must ensure the passenger safety, so requirements for the sensors is very high, considering the limitations of simulation, can only make the door opening and closed and some indication lamp display.
