Embodiment 1
[0048] figure 2 A flow chart of a video surveillance method based on Storm technology provided by Embodiment 1 of the present invention, such as figure 2 As shown, the video monitoring method is used to realize the processing and storage of video data, and the video monitoring method includes:
[0049] Step 101: The data source component Spout configures a label for the received video data, and obtains the address information of the storage node corresponding to the video data according to the preset distributed storage rules, and sends the video data to the corresponding storage node for storage, and the label The corresponding relationship with the address information is recorded in the corresponding relationship table.
[0050] In this embodiment, one data source component Spout corresponds to multiple storage nodes, and the user can preset corresponding storage rules to store video data in different time periods in a distributed manner. Storing video data through distr...
Embodiment 2
[0061] During the actual processing of the processing component Bolt, processing failures may occur due to factors such as data corruption and data loss. Embodiment 2 of the present invention provides a video monitoring method based on Storm technology.
[0062] image 3 A flow chart of a video monitoring method based on Storm technology provided by Embodiment 2 of the present invention, as image 3 As shown, the video monitoring method is based on a corresponding video monitoring system, and the video monitoring system includes a preprocessing module in addition to a Storm cluster and storage nodes; in addition, a cache backup node is also set in the Storm cluster. The video monitoring method is used to realize the processing and storage of video data, and the video monitoring method includes:
[0063] Step 100: The preprocessing module intercepts video data from the video data stream generated by the video sensor module, performs preprocessing on the video data, and then se...
Embodiment 3
[0078] Figure 4 A kind of video monitoring method based on Storm technology provided for the third embodiment of the present invention, such as Figure 4 As shown, the video monitoring method is based on a corresponding video monitoring system, and is used to dispatch video data required by users from the video monitoring system.
[0079] The video surveillance method includes:
[0080] Step 201: The data source component Spout receives the video scheduling instruction sent by the data control module, and according to the label of the video data to be scheduled contained in the video scheduling instruction, inquires the address information corresponding to the label from the correspondence table, and according to the inquired The address information requests the corresponding video data to be scheduled from the corresponding storage node.
[0081] In step 201, the user may send corresponding video scheduling instructions to the data source component Spout in each topology r...
