Technical study on the database of multiparameter state monitor and fault diagnosis system
多参量状态监测与故障诊断系统数据库技术研究

Based on the data characteristics of large state inspecting and fault diagnosis system, comparing the applicability of WinCC configuration database,Microsoft Access database and file system in managing date to this system, file system was chosen to manage data and memory alignment was adopted to design storing format. Practical application shows that this method can build up a high real-time and large database so as to meet the needs of industrial spots.
