电梯显示板的设计与制作 摘要 在现代社会和经济活动中，电梯已成为城市物质文明的一种重要标志。特别是在高层建筑中，电梯更是一种不可缺少的垂直运输工具。随着现代人对于电梯产品在安全性，稳定性，舒适性，美观性的要求不断提高，对电梯系统的各方面研究也显得尤为重要。而作为电梯控制系统中必不可少的一部分，电梯显示板的开发设计也需要不断发展。置于厅外的显示板又称电梯外呼板，提供给乘客及电梯技术人员使用。电梯外呼板将乘客及技术人员的需求信息通过CAN总线传达给电梯主板，电梯主板接收信息并执行相应的操作。同时，电梯主板将电梯的实时运行状态通过CAN总线传递给电梯外呼板。通过显示板的LED模块显示出来，供乘客读取。 本文根据电梯显示板的设计需求，给出详细的基于STM32系列32位微控制器的硬件设计方案。本文对本系统的PCB文件的绘制进行了总结。本设计主要偏向于硬件设计，软件部分用于实物的测试和调试，主要模拟了电梯的上下运行时，显示板的显示情况。 关键词：电梯，STM32，CAN ，显示，PCB THE DESIGN AND MANUFACTURE OF THE ELEVATOR DISPLAY BOARD ABSTRACT In modern social and economic activities, the elevator has become an important symbol of urban material civilization. Especially in high-rise buildings, the elevator is a kind of indispensable vertical transportation tools. With the modern constant improvement of the requirement of security, stability, comfort, aesthetics on elevator products, the study of all aspects of the elevator system is particularly important. However, as an essential part of the elevator control system, elevator display system also needs to develop. Display board in the hall board, also known as Hall call board can be used by the passengers and the elevator technicians .With the elevators Hall call board, needs information of passengers and technical staff can convey to the elevator main board via the CAN bus , and elevator main board receive information and perform the appropriate actions. At the same time, elevator main board through the CAN bus pass to real-time operating status of the elevator to the elevators call board. The status of the elevator will be displayed by the elevator display board, for the passengers to read. According to the elevator display board design requirements given in detail , this paper will design hardware circuit based on STM32 series 32-bit microcontrollers. This paper will summarize the drawing skills of PCB. The design tends to the hardware design, and the software part is used by testing and debugging, simulated the operating status of elevator.
