Embodiment Construction

[0065] The specific implementation of the method for the persistence of the arch dam pouring construction simulation object involved in the present invention will be described in detail below in conjunction with the accompanying drawings.

[0066]

[0067] Persistence Environment Description

[0068] The following takes the CBlocks class in the SQL Server 2000 database management system as an example to illustrate the persistence processing steps of the arch dam pouring construction simulation object instance.

[0069] Step 1. ORM persistence environment construction

[0070] The database table corresponding to the CBlocks class is the "casting block" table. In the execution of the simulation system, first instantiate the CBlocks class as Blks (there is only one instance in the execution), and the Items attribute in the Blks class saves the instance of the simulation object; FldTlts saves the mapping relationship between the instance attribute and the database table, as men...

Abstract

The invention provides a persistence method of an arch dam pouring construction simulation object, which can save a large amount of object information involved in the simulation process into a database. And the reconstructed simulation object can be retrieved from the database. Steps include: Step 1. building the persistence environment. 2, deriving a simulation object: selecting an instance of the simulation object; converting all attribute data to strings according to the instance attribute data type; generating the SQL statement to write the object into the database and submit the database,so as to complete the persistence of the object instance; persisting all instances as is. 3, recovering the simulation object: firstly, acquiring an association table of the object; selecting a record to restore; a new simulation object instance is created and an attribute is selected to obtain the attribute name and data type. Obtaining a corresponding value from the selected record; restoring the attribute data by using the value, type and offset of the attribute, and then restoring all the attributes of the instance. Restoring all instances of the emulated object.

Description

technical field [0001] The invention belongs to the fields of water conservancy and hydropower engineering construction, process simulation and computer application, and in particular relates to a method for persisting simulation objects of arch dam pouring construction. technical background [0002] The simulation process of arch dam pouring involves a lot of system status information. According to the requirements of scheme analysis and parameter debugging, it is necessary to save the data of class object instances in the system during the simulation process in the memory, and use the data to rebuild when needed simulation object. This process is called the persistence of simulation objects. The demand for this persistence mainly comes from the following three aspects: [0003] (1) Requirements for simulation dynamics. Arch dam pouring construction system is a dynamic system, and its system parameters change with time. For example: At the beginning of construction, ther...
