煤矿监控系统本质安全型互连认证方法研究

针对煤矿监控系统结构复杂多变、互连设备类型众多且不断增加的特点,分析了我国传统的本质安全型互连系统认证方法、国外的接口参数认证方法和系列本质安全型标准对我国煤矿监控系统本质安全型互连认证的适用性,指出目前煤矿监控系统本质安全性能的判定依据只能是GB3836.4-2000 equ IEC60079-11:1999,提出了煤矿监控系统非总线型接口设备本质安全型互连认证采用参数认证方法、总线型接口设备本质安全型互连认证目前应采用系统认证方法的方案,详细介绍了参数认证方法和系统认证方法的实施要点及未来实现总线型接口设备本质安全型互连参数认证的途径;还提出了煤矿监控系统接口设备的设计原则,以及煤矿监控系统本质安全型互连认证方法进一步的研究方向。该文有助于煤矿监控系统接口设备本质安全型互连参数认证方法的发展。

Research of Authentication Method of Intrinsically Safe Interconnection of Coal Mine Monitoring and Control System

According to characteristics of complex structure and various interconnection equipments with increasing quantity of coal mine monitoring and control system,the paper analyzed applicability of traditional authentication method of intrinsically safe interconnection system in China,interface parameter authentication method in the other countries and a series of intrinsically safe standards to intrinsically safe interconnection authentication of coal mine monitoring and control system in China,pointed out that the judging criterion of intrinsically safe performance of coal mine monitoring and control system is GB3836.4-2000 equ IEC 60079-11:1999 at present,and proposed a scheme that intrinsically safe interconnection authentication of non-bus mode interface equipments of coal mine monitoring and control system uses parameter authentication method and the authentication of bus mode interface equipments should use system authentication method at present.It introduced implementing key points of parameter authentication method and system authentication method in details and the way of implementing parameter authentication of intrinsically safe interconnection of bus mode interface equipments in the future.In addition,it proposed design principle of interface equipments of coal mine monitoring and control system and further research direction of authentication method of intrinsically safe interconnection of coal mine monitoring and control system.The paper will be good for development of parameter authentication method of intrinsically safe interconnection of interface equipments of coal mine monitoring and control system.
