It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0026] Figure 1 It is a structure schematic view of a multi-computing power board edge computing device for public security business provided according to an embodiment of the present application. The multi-computing power board edge computing device 100 comprises a switching chip 110 and at least one edge computing module 120, wherein each edge computing module 120 comprises a plurality of computing power boards 121.

[0027] The switching chip 110 and each computing power board 121 corresponding to the edge computing module 120 communicate through gigabit broadband, for receiving each video data stream and sending each video data stream to each computing power board 121.

[0028] Each video data stream is collected by each camera in a public security business scene, and each collected video data stream is sent to the switching chip 110. Each camera communicates with the switching chip 110 through gigabit broadband.

[0029] The edge computing module 120 is configured to analyze and process each received video data stream through each computing power board 121 to obtain a video data stream processing result.

[0030] Optionally, each camera is configured to collect one video data stream at the same time.

[0031] The cameras can be deployed in various public security scenarios to acquire real-time video data streams for each scenario. Each camera collects one video data stream simultaneously and processes that stream. For example, assuming N cameras can collect data streams concurrently, N video data streams can be acquired.

[0032] Optionally, the switching chip is a network address translation (NAT) switching chip; wherein, each computing board corresponding to the switching chip and the edge computing module includes one or more transformers.

[0033] Optionally, each video data stream from each of the cameras is transmitted to the network address translation (NAT) switching chip via a first network segment; the NAT switching chip performs NAT processing on the first network segment and transmits it to each of the computing boards via the resulting second network segment.

[0034] The switching chip is a network address translation (NAT) chip, which can convert the network segments of the input and output video data streams. For example, assuming the first network segment of the input video data stream is 192.100.xxx.01 and the processed target network segment (i.e., the second network segment) is 10.11.xxx.11, the NAT chip is needed to convert the network address.

[0036] In this embodiment, the main control board can also receive data interaction service instructions, perform data processing according to the received data interaction service instructions, and communicate with the network address translation switching chip and various computing boards through the network address translation switching chip.

[0039] In the embodiment, generally, each computing power board supports processing of 32 video data streams at most, and for eight computing power boards, processing of 256 video data streams at most can be supported. In addition, 24 video data streams are shared by the master control board, so that the first-type edge computing module can perform edge computing processing of 280 video data streams at most and is applied to a gigabit broadband network environment.

[0040] In addition, the second-type edge computing module is integrated by 10 first-type edge computing modules, each of which can perform edge computing processing of 280 video data streams at most, so that the second-type edge computing module can perform edge computing processing of 2800 video data streams at most.

[0043] Optionally, each computing power board corresponds to an embedded neural network chip.

[0044] In the embodiment, each computing power board can correspond to an embedded neural network chip. For the first type of edge computing module, the size of the module is small, which can be set to 20cmx20cmx10cm, and the average power consumption is as low as 50 watts.

[0045] Optionally, each computing power board supports hot plugging.

[0046] Among them, since each computing power board has the function of supporting hot plugging, different numbers of computing power boards can be set according to actual needs.

[0047] In the embodiment, different numbers of computing power boards can be accessed according to the number of cameras, and since the maximum number of video data streams processed by each computing power board is different, the computing power boards can be more flexibly increased or reduced, improving the flexibility of video data stream processing and better and more reasonably using the computing power boards.

[0051] For the first type of edge computing module 4, it includes 160 video data streams, and since each computing power board in the first type of edge computing module 4 (including computing power board 1, computing power board 2, computing power board 3, computing power board 4, computing power board 5, computing power board 6, computing power board 7, computing power board 8 and main control board) can process a maximum of 32 video data streams, computing power board 1, computing power board 2, computing power board 3, computing power board 4 and computing power board 5 each share 32 video data streams, and computing power board 6, computing power board 7, computing power board 8 and main control board are in idle state.

[0052] In the embodiment, the multi-computing power board edge computing device can further include: an access computing power board quantity statistical module, a computing power board access video data stream statistical module, and a computing power board state display module.

[0054] As a continuation of the foregoing example, 1000 cameras can be accessed by the computing power board access video data stream statistical module, that is, 1000 video data streams are accessed. The quantity of accessed computing power boards can be counted by the access computing power board quantity statistical module. Specifically, 8 computing power boards are accessed by the first type of edge computing module 1, 8 computing power boards are accessed by the first type of edge computing module 2, 8 computing power boards are accessed by the first type of edge computing module 3, and 5 computing power boards are accessed by the first type of edge computing module 4.

[0058] Further, when the computing power board 1 fails, it is necessary to transfer the 32-way video data stream processed by the computing power board 1 to other computing power boards, but since the computing power boards 2, 3, 4 and 5 are in a full load state, and the computing power boards 6, 7, 8 and the main control board are in an idle state, the 32-way video data stream in the computing power board 1 can be transferred to the computing power board 6, and the state of the computing power board 6 is updated.
