Abstract: In order to meet the needs of resource sharing and collaborative work,precursory data management system is in urgent need to establish a unified equipment resources effective management mechanism. According to actual characteristics of equipment and work demand of precursory data management system, we propose a model of equipment resource management system suit for seismic work application character. We abstract the information in the system and give a unified description so as to convert different equipment resources into a unified standard resource and finally shield the difference between the equipment and improve the extensibility of the system.The system achieves the optimization of the multi-user concurrent tasks and results data distributed processing,which is now running smoothly in the national earthquake precursor network.
