【摘要】：隨著人們對智能化產(chǎn)品需求的不斷擴大,嵌入式技術、數(shù)據(jù)傳輸技術、無線視頻監(jiān)控技術得到了快速的發(fā)展。與此同時,多媒體傳輸技術、視頻圖像采集技術和無線網(wǎng)絡通信技術對智能化產(chǎn)品的發(fā)展和應用也產(chǎn)生了重大的影響。由于WIFI無線網(wǎng)絡相比傳統(tǒng)的通信方式具有覆蓋面積大、布線比較簡單、傳輸速度快等優(yōu)勢,因此能夠應用在機電設備較為密集、空間范圍小、環(huán)境惡劣、有線電纜布線難度大的煤礦井下,以及滿足工業(yè)現(xiàn)場環(huán)境復雜危險的各種要求。然而,嵌入式處理器這些年來的發(fā)展迅速,它具有功耗低、體積小、經(jīng)濟實用、性能穩(wěn)定等特點,因此越來越多的技術也朝著與嵌入式結合的方向發(fā)展,例如視頻監(jiān)控技術。日常生活中智能手機作為當代每個人必不可少的一種隨身物品已經(jīng)不再是單一的通信設備,基于智能手機作為電子控制終端的產(chǎn)品已經(jīng)成為未來發(fā)展的一種趨勢。 本文提出了一種基于STM32的嵌入式微處理器無線視頻監(jiān)控車載系統(tǒng)設計方法。針對工作生活必不可少的PC機以及市場上主要流行的Android和iOS兩大操作系統(tǒng)手機,分別介紹了一種利用PC上位機和手機來控制WIFI視頻小車的方法。通過STM32主控制器來驅(qū)動小車直流電機,控制小車的各種運行狀況和驅(qū)動攝像頭采集視頻信息；車載系統(tǒng)上的攝像頭拍攝的視頻將通過WIFI信號傳給PC上位機或手機界面進行實時的顯示；PC上位機或手機能夠?qū)l(fā)出的控制信號傳給主控制器,從而達到了PC上位機或手機控制小車的目的。 系統(tǒng)總體設計思想可分為軟件設計與硬件設計：軟件設計主要是在一定的開發(fā)平臺上編寫程序、設計界面按鈕、實現(xiàn)系統(tǒng)的各種控制,分別設計了PC上位機以及兩種不同系統(tǒng)手機作為整個系統(tǒng)的控制端；硬件設計主要是系統(tǒng)的電路設計,包括電機驅(qū)動模塊設計、視頻采集模塊設計、無線通信模塊設計等幾部分。本文設計的無線視頻監(jiān)控智能小車制作出了實物,并通過了整體測試,基本功能全部實現(xiàn),整體效果比較理想。本系統(tǒng)的成功實現(xiàn)對未來智能家居以及防盜系統(tǒng)的發(fā)展提供了研究方向。
[Abstract]:With the increasing demand for intelligent products, embedded technology, data transmission technology, wireless video surveillance technology has been rapid development.At the same time, multimedia transmission technology, video image acquisition technology and wireless network communication technology also have a great impact on the development and application of intelligent products.Compared with the traditional communication mode, WIFI wireless network has many advantages, such as large coverage area, simple wiring and fast transmission speed, so it can be used in mechanical and electrical equipment, small space range, bad environment, etc.Cable wiring is difficult in underground coal mines and meets the requirements of complex environmental hazards in industrial sites.However, with the rapid development of embedded processor in recent years, it has the characteristics of low power consumption, small size, economy and practicality, stable performance and so on. Therefore, more and more technologies have been developed in the direction of integration with embedded systems, such as video surveillance technology.In our daily life, smart phone is no longer a single communication device as a necessary personal item for everyone. As a product of electronic control terminal, smart phone has become a trend in the future.This paper presents a design method of embedded microprocessor wireless video surveillance vehicle system based on STM32.This paper introduces a method of controlling WIFI video car by using PC and mobile phone, which is necessary for work and life, as well as two popular mobile phones such as Android and iOS, which are popular in the market.The main controller of STM32 is used to drive the DC motor of the car, to control the running condition of the car and to drive the camera to collect the video information.The video captured by the camera on the on-board system will be transmitted to the PC or the mobile interface through the WIFI signal for real-time display. The PC PC or the mobile phone can transmit the control signal to the main controller.In order to achieve the PC PC or mobile phone control car purpose.The overall design of the system can be divided into software design and hardware design: software design is mainly to write programs on a certain development platform, design interface buttons, and achieve various control of the system.PC and two different system mobile phones are designed as the control end of the whole system, the hardware design is mainly the circuit design of the system, including motor driving module design, video acquisition module design,Wireless communication module design and other parts.The wireless video surveillance intelligent car designed in this paper has made the object, and passed the whole test, the basic function is realized completely, the overall effect is quite ideal.The successful realization of this system provides a research direction for the future development of smart home and anti-theft system.
