Design Of De-Icing Vehicle Dispatch System Infrastructure Information System Based On COMPASS Techniques

In winter days, the snow and ice on aircraft must be washed off before the plane takes off to ensure the aircraft clean and aircraft aerodynamics, the procedure is called aircraft deicing. The adherence on aircraft will increase the weight of it and air resistance, which lead to the loss of the aircraft lift, stall ahead and other security risks. With the increase of flights, winter aircraft deicing is busy and stressful work, and it is becoming a hot spot of research how to complete aircraft deicing quickly and efficiently, realize aircraft deicing vehicle information automatically collected and managed to support scheduling system.Information automatic collecting and signals receiving system serves the intelligent dispatch system as a basic physical platform in this paper, the vehicle parameters such as tank oil level\deicing fluid level and vehicle position through BD2 are obtained and completed on-site vehicle as important field information. With de-icing vehicle information collection as the research content, Implementation of the parameters, electronic map location and integral information display, the commander can get field information on real-time with GPRS. All those signals transmission?collection and display procedure provide the basic information physical platform for intelligent de-icing dispatch system.To build a new kind of deicing dispatch information system platform using BD2 information system as the core, embedded technology software as the carrier, full consideration given to the special work process of deicing vehicles?the characteristics of S3C2440 processor and Linux during construction, a deicing operation information platform is developed for the scheduling system based on Compass.Firstly, it is discussed the scheduling system on the basis of systems and information technology requirements of the interface protocols, designed both hardware and software of information systems in detail. Secondly, the scheduling system grassroots platform schematics are drawn in detail, hardware and PCB board is designed,and the corresponding hardware debugging finished. During the design of the basic information in software,the paper gives a detailed design on the app and the process of the embedded Linux system. During the experiment the combination of hardware and software realized data transmission and display.experiment shows the deicing information system runs stablely convenient operation and has high feasibility.
