Abstract: Current safety monitoring and control systems of coal mine have many kinds and have no unified transmission protocol, format and contents, as well as interface, standard and protocol used in safety monitoring and control systems produced by different manufacturers, so it is difficult to realize data sharing, information integration for safety monitoring and control system and remote monitoring and networking for coal mine safety. To solve the problems, the paper proposed a design scheme of standard of data interface of safety monitoring and control system of coal mine. It analyzed purpose and principle of developing the standard and introduced structure and functions of three parts of the standard in details, namely information classification and cording, data file with text format and data file with XML format. Application of the standard can unifies contents and format of data exchanging in safety monitoring and control system of coal mine, so as to realize data sharing and data exchanging in management departments of coal mine.
