【摘要】:近几年,随着机场建设的不断发展,机场设备正朝着系统化、信息化和智能化的方向发展,车辆资源的管理和调度在机场运营中的作用日益突出。目前,机场车辆资源的调度是通过对讲机语音方式进行的,信息传输过程存在易丢失、不确定、反馈差和受环境影响大等缺点。 本文针对机场车辆调度中存在的问题,研究和设计一个支持多种通信方式、射频识别和文本显示的机场车辆调度智能终端(AVS)。AVS基于ARM微处理器,采用以GPRS数据传输为主,GSM短消息为辅的无线通信方式,并运用IC卡识别技术(RFID)管理AVS,LCD液晶屏作为信息显示设备。 在硬件电路设计中,重点完成了对多种无线通信方式的支持电路、IC卡识别电路和人机交互电路的设计。AVS主要包括主控制器、无线数据传输模块、IC卡模块和人机交互模块。主控制器选用Cortex-M3内核的微处理器STM32F103VC。无线数据传输模块选用内嵌TCP/IP协议栈的SIM300。IC卡模块是基于芯片RC522设计天线及其匹配电路。人机交互模块包含3.2寸LCD液晶屏、LED指示灯和键盘。主控制器分别通过串口、SPI接口和16位并口与GPRS模块、IC卡模块和LCD显示模块通信。 在软件研制上,为了实现安全可靠的无线通信、IC卡识别和LCD显示功能,完成了硬件驱动、实时操作系统移植、图形用户界面(GUI)和应用程序的设计和实现。硬件驱动是基于STM32F10X芯片的固件库来完成。实时操作系统通过移植μC/OS-Ⅱ达到系统的支持。GUI根据LCD液晶屏及其控制器配置μC/GUI进行开发。应用程序是根据AVS的功能需求进行设计和实现,主要包括任务流程及其优先级,以及任务间的通信方式。 通过对AVS中硬件和软件系统的调试、实验和运行表明,,各模块可以安全可靠地运行,经过进一步完善,系统可以满足机场车辆调度的需求。
[Abstract]:In recent years, with the continuous development of airport construction, airport equipment is moving towards the direction of systematization, information and intelligence. The management and scheduling of vehicle resources play an increasingly prominent role in airport operation.At present, the dispatching of airport vehicle resources is carried out by means of interphone voice. The information transmission process is easy to lose, uncertain, poor feedback and greatly affected by the environment.Aiming at the problems existing in airport vehicle scheduling, this paper studies and designs an intelligent terminal of airport vehicle scheduling based on ARM microprocessor, which supports various communication modes, radio frequency identification and text display.In this paper, GPRS LCD LCD LCD screen is managed by IC card identification technology, which is mainly supplemented by GPRS short message transmission, and it is used as information display device.In the hardware circuit design, the support circuit of various wireless communication modes is mainly completed. The design of IC card identification circuit and human-computer interaction circuit .AVS mainly includes main controller, wireless data transmission module, IC card module and human-computer interaction module.The Cortex-M3 microprocessor STM32F 103 VC is selected as the main controller.The SIM300.IC card module embedded in TCP/IP protocol stack is used in wireless data transmission module to design antenna and matching circuit based on chip RC522.The human-computer interaction module includes a 3.2 inch LCD LCD LED indicator and keyboard.The main controller communicates with GPRS module, IC card module and LCD display module through serial port and 16 bit parallel port respectively.In software development, in order to realize safe and reliable wireless communication, IC card recognition and LCD display function, hardware driver, real-time operating system transplantation, graphical user interface (GUI) and application program are designed and implemented.The hardware driver is based on the firmware library of STM32F10X chip.The real-time operating system can support the system by transplanting 渭 C / OS- 鈪
