Abstract


With the rapid development of embedded systems, semiconductors and Inetnret technology , embedded remote image transmission system based on Intenret is becoming a new hot topics . The development of embedded systems technology and network technology, image acquisition and transmission system based on embedded Linux and S3C2410 platform . The system via the USB camera to capture image data , Video4Linux module provides the interface for video capture program designed to achieve the picture of the network to send and receive real-time network transmission , multi-thread synchronization and other functions at the same time in order to meet real-time requirements , this the system was developed at the receiving end the receiving end interface . In this thesis, including hardware and software to achieve two major . Part of the hardware support USB camera to capture images , then the images collected by the Ethernet controller CS8900A data over the network to the receiving end ; software LINUX target board porting changes , while taking advantage of the TCP / IP protocol , the introduction of multi-threaded programming tools , network transmission memory alluding to the method of image data . Transmission in the network , in order to improve the reliability of the system transmission , at the same time taking into account the network may have a variety of data transfer paper also uses network flow control algorithm , and a certain improvement in the demand for embedded system image transfer , so that the image transfer is more stable and reliable , to some extent , reduces the system overhead , and gives the test results of the algorithm for the network flow control algorithm improvements . The paper also describes the end of the image acquisition software design . The test results show that the system is reliable , image acquisition and smooth, target reached in the LAN for remote environmental monitoring . System to reduce cost and improve the scalability and continuous upgrade capability to adapt to rapidly changing market has laid a good foundation .
