Description

Double-backup 5G intelligent terminal

Technical Field

Background

(1) Most of the existing acquisition equipment terminals adopt 4G networks for acquisition, and most of the acquisition terminal equipment is a single acquisition and reporting platform, so that the functions are relatively single.

(2) Most of the existing acquisition equipment terminals use a single network communication interface.

(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.

(2) When most of devices use a single network interface, in some real-time and special important scenes, a large risk exists, and it is not ensured that efficient networking work can be continuously maintained when the devices are abnormal (the network port interface is abnormal), so that the robustness is poor.

(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.
