【摘要】：當今社會擁堵的城市交通是大多數(shù)發(fā)達與發(fā)展中國家繼續(xù)面臨解決的問題，應對策略包括完善交通法規(guī)，合理規(guī)劃城市道路等，最直接的也是最高效的方法就是將車輛與道路結合，運用高科技技術規(guī)劃行車路線，保證行駛安全等功能。如今的車載管理系統(tǒng)市場可以說是種類繁多，他們相互競爭的核心則是管理系統(tǒng)的智能程度、硬件成本與軟件功能。隨著智能管理系統(tǒng)的服務要求逐步提高，因此研發(fā)一款功能完善，低成本高性能，開發(fā)周期短，易于維護升級的基于嵌入式的車載智能管理系統(tǒng)是很有必要的。 ARM與Android的結合媲美當年Intel與Windows的黃金組合，其充分利用ARM微處理器的高性能、低功耗、穩(wěn)定性強，擴展豐富的特點，外加Android操作系統(tǒng)的很好的兼容性、移植性，開發(fā)周期短，易于維護升級等優(yōu)勢決定了在消費品嵌入式領域作為應用產品的首選解決方案。多用于智能手機，智能家居，機頂盒與車載系統(tǒng)中。 采用ARM微處理器結合Android開源操作系統(tǒng)的汽車智能管理系統(tǒng)，其主要設計目標在于實現(xiàn)最優(yōu)行車路線規(guī)劃與GPS導航、保障行車安全、采用人臉識別技術防止車輛被盜以及自動泊車等功能。不是單獨以車輛為對象，而是將車輛、駕駛員與道路三者有機的結合在一起研究。 本文根據(jù)智能汽車管理系統(tǒng)的功能要求與應用領域，對嵌入式的硬軟件等各項技術進行了詳細的研究。在硬件方面，主要是外圍擴展電路的研究與硬件驅動的移植。在系統(tǒng)與軟件方面，主要研究了系統(tǒng)的移植與應用程序的開發(fā)。硬件平臺以三星公司的S3C2440微處理器為核心，，外部包括串口、觸摸屏、GPS/GPRS、TMPS在內的外圍設備電路。對這些硬件的工作原理，設計流程進行了詳細的研究與分析。在軟件方面，本文全面的分析Android操作系統(tǒng)的系統(tǒng)架構，并建立了一套完整的交叉編譯環(huán)境。成功的將Android系統(tǒng)的內核移植到S3C2440上，并主要修改開發(fā)了針對此平臺的觸摸屏，GPS，網卡，SD卡等外部設備的硬件驅動程序。應用程序方面，則著重靈活運用開源代碼的API接口函數(shù)完成GoogleMaps結合GPS的導航程序與人臉識別的安全防盜系統(tǒng)，以及胎壓胎溫監(jiān)控程序，提高了嵌入式設備的使用價值。通過本系統(tǒng)的研究與學習，將為移動終端嵌入式開發(fā)行業(yè)的同行在選擇方案，研究學習上提供具有價值的經驗。
[Abstract]:Nowadays, the congested urban traffic is a problem that most developed and developing countries continue to face. Countermeasures include perfecting traffic laws and regulations, rationally planning urban roads, and so on. The most direct and efficient method is the combination of vehicles and roads, the use of high-tech technology to plan the driving route, to ensure driving safety and other functions. Today's on-board management system market can be said to be a variety of, their core competition is the intelligence of the management system, hardware costs and software functions. With the gradual improvement of the service requirements of the intelligent management system, it is necessary to develop a vehicle intelligent management system based on embedded system, which has perfect function, low cost and high performance, short development cycle and easy to maintain and upgrade. The combination of ARM and Android is the same as the golden combination of Intel and Windows in that year. It takes full advantage of the high performance, low power consumption, strong stability, extensive and rich characteristics of ARM microprocessor, plus the good compatibility, portability and short development period of Android operating system. The advantages of easy maintenance and upgrade determine the application of embedded products in consumer products as the preferred solution. Most used in smart phones, smart homes, set-top boxes and vehicle systems. The automobile intelligent management system based on ARM microprocessor and Android open source operating system is mainly designed to realize the optimal route planning and GPS navigation, and to ensure the driving safety. Face recognition technology is used to prevent vehicle theft and automatic parking. Not only the vehicle as the object, but the vehicle, driver and road organic combination of research. According to the functional requirements and application fields of intelligent vehicle management system, the embedded hardware and software technologies are studied in detail in this paper. In the aspect of hardware, it is mainly the research of peripheral expansion circuit and the transplantation of hardware driver. In the aspect of system and software, the transplant of the system and the development of the application program are mainly studied. Hardware platform based on Samsung S3C2440 microprocessor as the core, external including serial port, touch screen, GPS/GPRS,TMPS and other peripheral devices circuit.
