【摘要】：近年来，随着嵌入式技术的发展，电梯的控制技术也得到了飞速的发展，同时，随着触摸屏的出现及其技术的日益成熟，触摸屏也渐渐普遍应用于各行各业，并且日益受到人们的青睐。传统的电梯显示器多为LED，显示内容单调、有限，而电梯轿厢内楼宇广告，显示系统多采用独立广告机，成本高。因此，利用触摸屏和嵌入式技术设计和开发一套集显示和触摸式楼层选择一体的电梯轿内控制器，可以更好的提高电梯的品质。本文主要从硬件和软件设计两个方面研究基于StellarisWare图形库的电梯轿内控制器。在硬件方面，以ARM7微处理器LPC2478为中心，，设计了平板式显示单元、液晶触摸电路、CAN通信接口，扩展了TFT-LCD显示功能、液晶触摸功能及外部存储器功能，构建一个完整的嵌入式硬件平台。软件设计方面，首先在驱动平板显示器的基础上，移植了嵌入式图像模块StellarisWare，设计了人机交互及多媒体界面；其次是触摸屏软件设计，包括定位触摸点位置，设置用户输入及驱动，响应用户事件，更新显示界面等；最后，在通信方面，利用CAN实现电梯轿内控制器与电梯其它控制器单元之间进行实时、可靠地通信。该控制器设计的触摸式人机交互及多媒体界面简单、方便、美观大方，CAN通信可靠、稳定，图像显示清晰、效果良好，适用于高档电梯。
[Abstract]:In recent years, with the development of embedded technology, elevator control technology has also been rapid development, at the same time, with the appearance of touch screen and the increasingly mature technology, touch screen has gradually been widely used in various industries. And increasingly favored by people. The traditional elevator display is mostly LED, display content monotonous, limited, and elevator car building advertising, the display system mostly uses independent advertising machine, the cost is high. Therefore, using touch screen and embedded technology to design and develop a set of display and touch floor selection of the elevator interior controller, can better improve the quality of the elevator. This paper mainly studies the elevator interior controller based on StellarisWare graphics library from two aspects of hardware and software design. In the aspect of hardware, a flat panel display unit, a LCD touch circuit and a CAN communication interface are designed with ARM7 microprocessor LPC2478 as the center. The functions of TFT-LCD display, LCD touch and external memory are extended. Build a complete embedded hardware platform. In software design, firstly, the embedded image module StellarisWare, is transplanted to design the human-computer interaction and multimedia interface on the basis of driving the flat panel display, and the second is the touch screen software design, including the location of the touch point. Set up user input and driver, respond to user events, update display interface, etc. Finally, in the aspect of communication, we use CAN to realize real-time and reliable communication between the controller in elevator sedan chair and other controller units of elevator. The touch-touch human-computer interaction and multimedia interface designed by the controller are simple, convenient, beautiful and generous, CAN communication is reliable, stable, the image display is clear, the effect is good, and it is suitable for high-grade elevators.
