Design Of WLAN Video Transmission System Based On STM32 And MiCO

In recent years,"Internet of things" appears on the Internet frequently,and more and more people pays attention to it.In the early two thousand,"Internet of things" is just a concept,but now Internet technology has come true,which has become one part of our life.At the same time embedded chip technology has become more and more mature.It is not only small and powerful,and power consumption is gradually reduced.At the times when the technology is developing rapidly and material is also increasingly rich.It is very important that how to make advanced technology apply better and become convenient to life.This design combines the latest embedded technology and Internet technology together.It contains a set of local area network wireless video transmission program.The program is based on the recent rise of the MiCO Internet operating system.The system adopts the modular design,and it is divided into the remote control terminal of the host computer and the data acquisition terminal of the lower computer.The host computer uses C # WPF and integrates serial debugging assistant's and network debugging assistant's classic function.What's more,it combines with WPF Image to decode and display the video stream.And finally according to the actual needs it adds storage,timing and other functions,to achieve the control of the data acquisition side of the lower computer and the receiving of the data.The lower computer data acquisition terminal is based on the STM32F429 master chip.It is transplanted the MiCO Internet real-time operating system,and equipped with the matching EMW1062 WIFI module.Through the OV2640 digital camera to collect image information and the camera internal compression of the data processing,the output of the JPEG video data can upload to the host computer through the wireless network,and can show a smooth image in the host computer's real-time video reception area.After testing,this design finally realized LAN wireless video transmission system based on STM32 and MiCO,it has characteristics of a simple structure,a small size and stable performance.It can not only be used in the field of monitoring,but also be applied to detect the robot or UAV and other fields to report remote real-time visual information.It has a wide range of applications in the future.
