Embodiment Construction

[0044] The specific embodiment of the present invention is described in further detail below in conjunction with accompanying drawing:

[0045] see figure 1 As shown, this embodiment proposes a storage system with N+1 redundancy function, including a camera, an IP-SAN array, and a store-and-forward server. The store-and-forward server receives the video stream sent by the camera and stores it in the storage device , the storage devices include N storage devices and one redundant storage device.

[0046] The composition and functions of each part are as follows:

[0047] Camera: here generally refers to the equipment that can transmit video to the monitoring center through the network, which can be a combination of analog camera and encoder, or a network camera. The camera video transmission method is not limited, unicast, multicast, on-demand, and streaming media forwarding are all available. The function of the camera is to collect front-end video, encode and compress the ...

Abstract

The invention discloses a storage system with an N+1 redundancy function and a method. The system comprises a camera, storage equipment and a store-and-forward server, wherein the store-and-forward server receives a video stream sent by the camera and stores the video stream into the storage equipment; the storage equipment comprises N storage equipment parts and redundant storage equipment; and the store-and-forward server comprises a forward cache module, a storage management module, a redundant switching module, a redundant recovery module and a data backup module. The storage system effectively solves the problem that a large number of videos are lost after the storage equipment is damaged; the automatic data backup during the redundancy period ensures the data integrity after redundancy recovery and clear subsequent redundancy switching; the plan protection during redundancy switching and recovery ensures normal operation of the system; the stream cache during forwarding ensures the videos to be stored during redundancy switching and recovery; and the nondestructive storage of the system is ensured.

Description

technical field [0001] The invention relates to the technical field of video monitoring and video storage, in particular to a storage system with N+1 redundancy function. Background technique [0002] With the development of high-definition IP cameras, network high-definition surveillance applications have become an important direction of development; with the continuous expansion of video surveillance scale, it is impossible to view real-time videos of all cameras at the same time, and historical videos have become important data in the video surveillance industry. At the same time, with the increase of the monitoring quantity, the storage capacity will also increase rapidly. For large-scale historical video data, how to ensure the integrity of the video data is as important as ensuring the image quality of the video data. [0003] In the existing video storage systems, most of them rely on RAID, hot spare disk, and regular backup supported by IP-SAN arrays for data secur...
