The mid-end transmission layer is the “nerve center” of the system, aimed at solving transmission difficulties caused by no public network coverage and complex terrain (mountains, deserts, ravines) in uninhabited areas. It adopts the “Industrial-grade Mesh Ad Hoc Network + Wireless Bridge Relay” mode to build a wireless backbone network, realizing stable transmission of all front-end data (video, voice, positioning) to the back-end control center. The specific design is as follows:

1. Transmission Topology Design (Fitting Terrain of Uninhabited Areas, Avoiding Occlusion)

Combining the terrain characteristics of uninhabited areas (mountainous, ravines, prone to signal occlusion), a topology structure of “Core Node + Relay Node + Terminal Node” is adopted. The core node is deployed in the temporary command center, relay nodes are deployed on high ground (unobstructed), and terminal nodes are front-end equipment at various construction points. The specific topology is as follows:

• Core Node: 1 unit, deployed in the temporary command center, using a high-performance industrial-grade Mesh gateway, responsible for aggregating data from all relay nodes and terminal nodes, connecting to back-end control equipment;
• Relay Node: 2-3 units (per 10km construction section), deployed on high ground within the construction area (such as mountain tops, highlands), using industrial-grade wireless bridges (supporting relay mode), responsible for forwarding signals between terminal nodes and the core node to solve terrain occlusion problems;
• Terminal Node: 1 unit per construction point, i.e., the Mesh Ad Hoc network terminal deployed at the front end, responsible for collecting front-end data and transmitting it to the relay node or core node (unobstructed points can transmit directly to the core node).
