To address the wireless communication requirements of pilot protective and rescue equipment in high-density and close-range environments, this study proposes an adaptive networking solution based on Bluetooth Low Energy (BLE) technology. By innovatively designing a dynamic wireless networking scheme and optimizing low-power strategies, a wireless network architecture supporting collaborative operation of 32 nodes has been successfully developed. Experimental results demonstrate that the system can stably establish a dual-layer clustered topology network in high-density scenarios, achieving reliable dual-hop transmission of data packets up to 244 bytes. This research effectively resolves the limitations of traditional wired transmission methods, such as complex cabling, excessive weight, and poor scalability. It provides robust wireless communication support for critical functions including real-time monitoring of pilot physiological parameters and restraint status sensing. Additionally, the proposed framework offers a reference technical solution for other high-density IoT applications.
