汽車行駛狀態(tài)紀(jì)錄儀開發(fā)畢業(yè)設(shè)計

摘要

隨著飛機(jī)飛行數(shù)據(jù)記錄儀在空運(yùn)管理方面的成功運(yùn)用，汽車行駛狀態(tài)記錄儀已陸續(xù)在許多國家和地區(qū)大量使用。
該汽車行駛狀態(tài)記錄儀在發(fā)生交通事故時，能客觀、全面地記錄交通事故發(fā)生時車輛行駛的各種狀態(tài)和司機(jī)的操作行為，為交通事故分析提供真實(shí)、有效、科學(xué)的有關(guān)車輛行駛的原始數(shù)據(jù)，并可提供事故分析功能，幫助有關(guān)部門快速確定事故原因，以保障事故雙方(或幾方)的合法權(quán)益；在正常營運(yùn)中，又是管理部門加強(qiáng)監(jiān)督和管理的強(qiáng)有力工具，幫助管理人員全面了解汽車的運(yùn)行情況；在車輛發(fā)生故障時，它又可提供故障診斷功能，為維修人員判斷故障提供可靠、準(zhǔn)確的科學(xué)依據(jù)。汽車行駛狀態(tài)記錄儀的推廣，將在遏止疲勞駕駛、車輛超速等嚴(yán)重交通違章、約束駕駛?cè)藛T駕駛行為、預(yù)防道路交通事故、保障車輛行駛安全、提高營運(yùn)管理水平等諸多方面發(fā)揮重要作用。
關(guān)鍵詞：原始數(shù)據(jù)；診斷功能；科學(xué)依據(jù)

Abstract

Record an instrument along with the airplane flight data Be transporting management by air of successful usage，the car drives an appearance record an instrument already continuously in many nations and a great deal of usage in the region.
That car drives an appearance record an instrument while taking place traffic accident,The vehicle drove when ability was objective and recorded traffic accident occurrence completely of the operation behavior of various appearance and driver, for the traffic accident analysis provide reality, valid, science of the relevant vehicle drive of original data, can provide the trouble analysis the function also, help department concerned to make sure trouble reason quickly,to protect both incidents (or parties) of the legitimate rights and interests; In normal operation, of management departments to strengthen supervision and management of the powerful tools to help manage the staff have a comprehensive understanding of the operation of the vehicle; in the vehicle breaks down, it can provide fault diagnosis and maintenance staff to provide a reliable judgment fault, accurate scientific basis. Vehicle State Recorder promotion, will stop fatigue driving, speeding and other serious traffic violations, bound drivers driving behaviors, the prevention of road traffic accidents, traffic safety protection, improve operational management level and many other aspects play an important role.
Key words : raw data; Diagnostic function; Scientific basis
