Abstract： Aiming at the current status quo that in industrial site, security monitoring field and automotive electronics industry camera acquisition′s environment building is complex, the cost is high，and the function is single，this paper designs and develops a network monitoring image processing platform based on HiSilicon chip. The platform is designed to use a combination of NVR and DVR, which can not only view, browse, play back, manage, and store multiple network camera video streams at the same time, but also perform image calculations, with the function of image/voice and dynamic frame control. The system adopts the design architecture of HiSilicon HI3559AV100+HI3531DV200 dual CPU, utilizes the excellent video processing capability of HI3559AV100, the excellent codec capability of HI3531DV200, the basic system of the system package CPU, the high-definition video interface circuit and the power supply circuit. The platform can receive video streams through the network, with a maximum decoding capacity of 16 channels of 1080p30, and supports 2 sets of high-definition heterologous outputs. The design has been verified by the actual engineering prototype, the image output is clear and smooth, and the system runs stably. It can be used to meet the application requirements of different scenarios, and also has the advantages of simple operation and wide applicability.
