Abstract: In view of the problem that performance of safety monitoring and control system of coal mine can’t accord with relevant standards and criterions in actual application,the paper proposed a design scheme of evaluating software of in-use safety monitoring and control system of coal mine.It analyzed principle of the evaluating software,and introduced design and implementation of system information (maintenance) module,analysis and display module of evaluating data and data synchronization function module of the evaluating software in details,and gave operation flow of the evaluating software.Combing with embedded on-line detecting device,the evaluating software can finish evaluating task for performance and use and maintenance of safety(monitoring) and control system of coal mine.
