(3) The multi-network interface of the existing acquisition equipment uses a single-line protocol of TCP.
The following disadvantages are associated with the above-mentioned acquisition devices:
(1) the problems of high delay, low bandwidth, limited data quantity of the acquisition equipment and the like can be caused in scenes of densely deployed acquisition equipment, high-flow acquisition reporting time and high real-time requirement due to the fact that 5G signals cannot be applied, and networking interaction and functionality of the equipment are influenced.

(3) A small part of acquisition equipment uses a multi-network interface for acquisition, but uses a single line protocol of TCP, so that when network interfaces are switched, TCP connection is disconnected, and then reconnection time consumption is increased.
