摘要
如何解决资源与能力之间的矛盾是嵌入式开发的关键。该文在基于MCU(如单片机)或者同等级别的平台上,从系统级层面探究了实现网络视频传输的框架,并基于STM32F103单片机,采用软件方式实现TCP/IP协议栈,采用OV7670图像传感器和FIFO芯片AL422B实现图像采集模块,采用SPI网络控制器实现ENC28J60通信模块,设计完成了基于网络的视频图像传输系统,探讨了系统中各个模块对资源的需求,以及需要解决的问题。该视频图像传输系统可用于远程作业、家居等图像要求不高的网络图像实时监控。
How to solve the contradiction between resources and capabilities is critical for embedded development. In this paper, a framework of network video transmission based on MCU (such as SCM)or the same level of the platform is studied, a framework of network video transmission from the system level is implemented, and TCP/IP protocol stack is implemented using a software based on STM32F103 single chip computer, image collection module is realized using OV7670 image sensor and the FIFO chip AL422B, the ENC28J60 communications module is implemented by SPI network controller. This paper designs a network - based video image trans- mission system, and discusses the resource requirements of each module in the system and the problems to be solved. This video image transmission system can be used for remote jobs, Home and others image less real - time network monitoring.
