Abstract:Dynamic management of the monitoring sensor in the development of dam safety monitoring information system is studied. By use of the dynamic management technique, the ill influence of invalidation, change or reconstruction of the monitoring sensor is avoided, and the flexibility, adaptability and transplantability are enhanced. The primary principle of dynamic management is expatiated. The kernel is to separate the information of monitoring sensors from the program code and the database structure, and then, use the program compiler to add and edit, and use the knowledge of the sensors. Some key techniques are discussed in detail, including the separation and combination of monitoring instruments for disposing information uniformly, and the database structure adopted for simplifying the dynamic management. The solution of some problems in the course of dynamic management is introduced, such as the dynamic management of instrument types and association of monitoring sensors.
Keywords:dam safety monitoring information system  sensor  dynamic management
