Wireless multi-parameter monitoring system for specialized combustion furnace operating conditions based on a layered protocol stack

To address the issues of complex wiring, poor scalability, and insufficient real-time performance and reliability in complex electromagnetic environments associated with traditional wired operational monitoring systems for specialized combustion furnaces, this paper designs and implements a multi-parameter acquisition system based on Zigbee wireless communication. The system hardware employs a highly integrated modular design encompassing multi-level power management, high-precision acquisition from multiple sensor sources, signal conditioning, and wireless transmission modules. This enables low-power, reliable acquisition of critical parameters such as temperature, pressure, and flow rate. At the software level, an innovative hierarchical protocol stack (R-CS-TDMA) is proposed, integrating Coordinated Central Time Division Multiple Access (CS-TDMA) with Time-Slot Dual Acknowledgment Reliable Transmission (TS-DART). This mechanism effectively prevents multi-node access conflicts through time-division scheduling and bidirectional acknowledgment handshakes, ensuring deterministic and highly reliable data transmission. This research provides a highly reliable, low-power, and easily deployable wireless monitoring solution for specialized combustion furnaces, holding significant application value for advancing their intelligent and green development.
