This study focuses on hardware design upgrades for the electro-hydraulic monitoring system of scraper conveyors, exploring a hardware platform based on the KuangHong operating system. A hardware architecture was developed by creating an adaptable platform that replaces existing programmable logic controller components. Leveraging KuangHong’s soft bus capabilities, the system enables multi-device wireless coordination, supports an intelligent working face mode for "one device controlling multiple units," and ensures reliable data transmission through multi-mode communication and the MDTP protocol, significantly enhancing operational intelligence. The hardware utilizes domestically developed chips, reducing supply chain risks associated with foreign technology. The control system has been successfully deployed at China Coal Group’s Yamai Daning Coal Mine, where four units accurately collect data from 50 sensors on the conveyor’s drive section and transmit it in real time via the soft bus to the central control center, enabling continuous status monitoring .
