Abstract: Aiming at the shortages of simulative camera used in coal mine underground, the paper proposed a design scheme of IP camera based on digitization technology, introduced design and implementation of digitization IP camera in details. The hardware of the digitization IP camera took Z228 multimedia processing chip as core,the software of the digitization IP camera took Linux as core,which not only realized digitization, network and intelligentize of video monitoring and control system of mine, improved performances and stability of video monitoring and control system of mine, but also has advantages of high integration level, simple structure, easy to develop, low cost and easy to use etc.
