Abstract: 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...更多 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.
