Abstract: Abstract: As the core of coal transportation in underground mining, the level of intelligence of scraper conveyor equipment directly affects the overall intelligence level of the working face construction and determines the level of mine intelligence construction.In order to thoroughly solve a series of problems, such as redundant data, difficulty in information exchange, shallow data mining, and sluggish control system response, which are caused by the disunity of system architecture, standards and protocols in the development of intelligent scraper conveying equipment, the overall framework of intelligent scraper conveying equipment based on the MineHarmony operating system is built with the research background of the Internet of Things architecture based on the MineHarmony operating system built by China Coal Energy Group, to improve the interconnection efficiency, collaborative control capability, and distributed data management level within and between systems, while simplifying the control units, eliminating the mutual interference of active signals, and improving the security and reliability of the intelligent control system.Firstly, the deep integration of the sensing of working conditions such as reducer oil temperature, oil level, bearing temperature, motor bearing and winding temperature, cooling water pressure, flow rate, temperature, and sprocket bearing temperature, as well as the real-time monitoring of the force status of the central connecting dumbbell and the operation status monitoring of the drive chain, was carried out on the MineHarmony operating system platform, comprehensively improving the accuracy and stability of intelligent sensing of scraper conveying equipment. Secondly, based on a comprehensive analysis of the operating data and factors related to adaptive speed regulation of the scraper conveyor equipment, combined with the theoretical calculation of the real-time coal volume of the scraper conveyor equipment, an intelligent speed regulation strategy and process for the scraper conveyor equipment were developed, achieving continuous and efficient operation of the scraper conveyor equipment.Thirdly, in response to the problem of delayed response in the control system during the operation of the automatic telescopic tail of the scraper conveyor equipment, the advantages of real-time interconnection of the distributed soft bus of the MineHarmony operating system were utilized to analyze the relationship between the scraper chain load and chain tension changes, and optimize the chain tension control process of the scraper conveyor equipment. Finally, the intelligent control system based on MineHarmony has carried out an underground industrial test in China Coal Yamei Daning Coal Mine. Through the soft bus technology and MDTP transmission protocol of MineHarmony system, the interconnection and cooperation between scraper conveying equipment and mining supporting equipment at working faces such as shearers and hydraulic supports are realized.Industrial tests have shown that the MineHarmony operating system has achieved a unified system architecture, unified standards and protocols, interconnectivity, intelligent collaboration and distributed data management, safety and trustworthiness. It can collect real-time key parameters such as the operating status, fault information, motor temperature, load, etc. of scraper conveying equipment, and display and process complex data. Combined with the optimization of intelligent control functions such as dumbbell status monitoring, adaptive speed regulation of scraper conveying equipment, and fully automatic chain tensioning, the intelligence level of scraper conveying equipment has been comprehensively improved. All functions and performance indicators have met the design requirements, providing reference for the comprehensive promotion of intelligent detection, intelligent control, and intelligent diagnosis of scraper conveying equipment in the MineHarmony operating system.
