矿井通风仿真系统数据库设计

Database design of simulation of mine ventilation system

针对矿井通风系统特点和数据库技术发展状况,采用数据库代替数据文件对矿井通风仿真系统属性数据进行管理。整个系统采用面向对象程序设计方法进行设计,为了和网络解算相一致,系统主要分为以下几类对象:巷道对象、结点对象、构筑物对象、通风动力装置对象等。把管理数据库对象指针封装在对象中,使得数据库和矿井仿真系统对象进行无缝连接,解决矿井通风仿真系统属性数据和实体不一致问题,提高了系统仿真效率。通过对象间相互发送消息,能够有效建立和管理拓扑关系。

According to the characteristic of mine ventilation system and the development of database, the database was used to manage the attribute data of simulation of mine ventilation .The program was designed by using object-oriented method, The system objects were classified tunnel object, joint object ,the structure of mine ventilation object and the drive object etc. A pointer of database record object was encapsulated in the object, thus it can keep the object of the simulation of mine ventilation system and the database consistent. The effective management and instauration of topology relationship were built by object sending and receiving messages.
