【摘要】：近幾年，隨著機(jī)場(chǎng)建設(shè)的不斷發(fā)展，機(jī)場(chǎng)設(shè)備正朝著系統(tǒng)化、信息化和智能化的方向發(fā)展，車輛資源的管理和調(diào)度在機(jī)場(chǎng)運(yùn)營(yíng)中的作用日益突出。目前，機(jī)場(chǎng)車輛資源的調(diào)度是通過(guò)對(duì)講機(jī)語(yǔ)音方式進(jìn)行的，信息傳輸過(guò)程存在易丟失、不確定、反饋差和受環(huán)境影響大等缺點(diǎn)。 本文針對(duì)機(jī)場(chǎng)車輛調(diào)度中存在的問(wèn)題，研究和設(shè)計(jì)一個(gè)支持多種通信方式、射頻識(shí)別和文本顯示的機(jī)場(chǎng)車輛調(diào)度智能終端（AVS）。AVS基于ARM微處理器，采用以GPRS數(shù)據(jù)傳輸為主，GSM短消息為輔的無(wú)線通信方式，并運(yùn)用IC卡識(shí)別技術(shù)（RFID）管理AVS，LCD液晶屏作為信息顯示設(shè)備。 在硬件電路設(shè)計(jì)中，重點(diǎn)完成了對(duì)多種無(wú)線通信方式的支持電路、IC卡識(shí)別電路和人機(jī)交互電路的設(shè)計(jì)。AVS主要包括主控制器、無(wú)線數(shù)據(jù)傳輸模塊、IC卡模塊和人機(jī)交互模塊。主控制器選用Cortex-M3內(nèi)核的微處理器STM32F103VC。無(wú)線數(shù)據(jù)傳輸模塊選用內(nèi)嵌TCP/IP協(xié)議棧的SIM300。IC卡模塊是基于芯片RC522設(shè)計(jì)天線及其匹配電路。人機(jī)交互模塊包含3.2寸LCD液晶屏、LED指示燈和鍵盤。主控制器分別通過(guò)串口、SPI接口和16位并口與GPRS模塊、IC卡模塊和LCD顯示模塊通信。 在軟件研制上，為了實(shí)現(xiàn)安全可靠的無(wú)線通信、IC卡識(shí)別和LCD顯示功能，完成了硬件驅(qū)動(dòng)、實(shí)時(shí)操作系統(tǒng)移植、圖形用戶界面（GUI）和應(yīng)用程序的設(shè)計(jì)和實(shí)現(xiàn)。硬件驅(qū)動(dòng)是基于STM32F10X芯片的固件庫(kù)來(lái)完成。實(shí)時(shí)操作系統(tǒng)通過(guò)移植μC/OS-Ⅱ達(dá)到系統(tǒng)的支持。GUI根據(jù)LCD液晶屏及其控制器配置μC/GUI進(jìn)行開發(fā)。應(yīng)用程序是根據(jù)AVS的功能需求進(jìn)行設(shè)計(jì)和實(shí)現(xiàn)，主要包括任務(wù)流程及其優(yōu)先級(jí)，以及任務(wù)間的通信方式。 通過(guò)對(duì)AVS中硬件和軟件系統(tǒng)的調(diào)試、實(shí)驗(yàn)和運(yùn)行表明，，各模塊可以安全可靠地運(yùn)行，經(jīng)過(guò)進(jìn)一步完善，系統(tǒng)可以滿足機(jī)場(chǎng)車輛調(diào)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
