Special Vehicle Wireless Data Acquisition Design And Implementation

Traditional vehicle data collection methods are attendant on the car, with the storage devices connected to the vehicle traveling data recorder to collect data, and then import the computer after, inefficient, cumbersome, complicated operation. Wireless local area networks based on Wi-Fi (Wireless Fidelity) technology applied everywhere, features are:easy to install, flexible; easy to plan, adjust, expand; has some movement type, for traditional wireless data communications to provide a new application model, based on the vehicle Wi-Fi technology for wireless data acquisition in this context emerged.The thesis mainly includes following contents:(1) The status of the special vehicle wireless data collection technology studies were analyzed for special wireless data acquisition key technologies are analyzed and described;(2) The special vehicle wireless data acquisition needs analysis, describes the acquisition of the design goals and functional requirements, and as a basis for the design of the overall structure of the collector, the detailed analysis and design of the vehicle wireless data acquisition on the basis of device, the acquisition includes a microcontroller module, Wi-Fi module, network module, memory module, display module, audio module, the key modules, power modules and data acquisition software;(3) The special vehicle wireless data acquisition and operation are described, tested the performance collector, and through participation in the actual operation of a fleet acquisition of application results were analyzed;(4) On the remaining issues to analyze and propose solutions.The special vehicle wireless data acquisition actual deployment of applications, making the vehicle traveling data recorder data collection without human involvement, automatically collected data storage, analysis, transmission, improved efficiency, increased reliability, accuracy, liberated human, for the prevention, treatment team irregularities play a key role.
