Research And Realization Of Intelligent Terminal For Airport Vehicle Scheduling

In recent years, with the continuous development of airport construction, airport equipment ismoving in a systematic, information and intelligent direction，the role of resource management andscheduling of vehicles in the airport operations has been increasingly broken out. Currently, theairport use the radio voice to schedule the vehicle resource.The shortcomings by this way are that theinformation is easy to lose and uncertain, has poor feedback and subject to environmental impact.In this thesis,we research and design a intelligent terminal that be named as AVS for the problemof airport vehicle scheduling.AVS could support multi-communication, radio frequency identification,and text display. AVS is based on ARM microprocessor, take the wireless communication of GPRSand GSM short message to transmit data, introduce the IC card identification (RFID) technology tomanage, and use the LCD screen as information display device.In the process of the hardware circuit design, we centralize to complete the circuitry of multi-communication, IC card identification and man-machine conversation. AVS includes the maincontroller, wireless data transmission module, IC card module and man-machine module. The maincontroller is microprocessor STM32F103VC which is based on the Cortex-M3core. The wireless datatransmission module use SIM300that is embedded TCP/IP protocol stack. IC card module is basedon chip RC522to design the antenna and matching circuit. Man-machine module includes3.2inchLCD screen, LED indicators and keyboard. The main controller communicate with GPRS module, ICcard module and LCD display module through the serial port, SPI interface and16-bit parallel port.In the aspect of software, We design and realize the driver of hardware, real-time OS migration,graphical user interface (GUI) and application to achieve the function of wireless communications, ICcard identification and LCD display. Hardware driver is based on the STM32F10X firmware library.The μC/OS-Ⅱ is migrated as real-time OS to support the system. The design of GUI is based onLCD screen and its controller to configuration μC/GUI. We according to the demands of AVS todesign and realize, which include the task flow, priority and communication.After dubug,test and run the hardware and sofeware sysytem of AVS，we could prove that eachmodule can operate safely and reliably, system can meet the needs of the airport vehicle schedulingwith further improvement.
