Moreover, the cables are easily disturbed by external factors during the placement process, affecting the entire defense process, but there is a lack of real-time observation methods. Observation through manual probes has safety hazards. Therefore, designing and manufacturing large-scale wire-laying equipment will cause economic waste, low cost performance, and is not conducive to promotion and use. Utility Model Content
