Abstract:The Cangzhou Iron Lion is the biggest cast iron antique.Because Cangzhou Iron Lion is difficult to be protected in the open air,it is necessary to take real time monitor on it,using special health monitoring system.The data management and integration system is exploited, it is one of the core of health monitoring system.The central database is built by SQL Server 2005 and the human computer interface is designed by Delphi,the corresponding data analysis program is also developed;the system integration platform is set up by Delphi, and coordinates various subsystems of the health monitoring system of Cangzhou Iron Lion to cooperate smoothly,and all relevant interface programs are compiled including the structural analysis software of ANSYS,MATLAB,etc; an in depth study and analysis is carried out for the structural safety assessment methods,a number of effective and practical methods are put forward and realized in programs.Most research results are successfully applied on local experiment of Cangzhou Iron Lion structure Health monitoring system,providing much valuable basic reference information for long term structure health monitoring.
