Current status and development trend of core control technology for coal mining and tunneling equipment

In order to solve the outstanding problem faced by the coal mining and tunneling equipment control system that the platforms and standards were not uni form,and find the urgent core control technologies of equipment,this paper analyzed the domestic and international technical status of the mining and tunneling equipme nt core control structure,the application of embedded software system and embedded soft PLC in equipment,communication protocol standard,and the application of ce ntralized control system software.This paper proposed a platform-based,standardized technical solutions of equipment core: based on serialization of core unit hardwar e,unified application software and centralized control system configuration development platform,unified communication protocol standard, solutions constituted a unifie d platform for software development,testing,and publishing.The key technologies of the proposed solutions were analyzed: technology of core control units' intrinsic saf ety,anti-interference,protection and heat dissipation; related development technologies of embedded real time operating system; embedded soft PLC platform technolog y; related technologies of interconnection and interworking protocol;centralized control system standard configuration development technology,etc,and proposed a netw ork access architecture and communication system architecture that used Ether Net/IP to achieve consistency and interoperability. Finally,this paper pointed out that pla tformization and standardization, unified management,interconnection,networking and multimedia of equipment,functional safety,network security and the real-time contr ol of core,and intelligent control were the technical direction of equipment core.The solutions facilitated integrating intelligent core control function into equipment,realiz ed the digital access and centralized control of the fully-mechanized mining face and heading face ,formed a unified ,benign and self-safe system development ecology.
