Summary of implementation technology of design information integrated management system

Daqing Oilfield Engineering Co., Ltd. has built a design information integrated management system in combination with the engineering design management process. The electronic safe technology of the system can be extended to the distributed electronic safe technology. The whole module of workflow management subsystem is composed of database, kernel layer, function layer and interface layer. In the development process of workflow management subsystem, the object-oriented development method is adopted. The process of designing business is abstracted as an entity superclass, and every step in the process can be abstracted into use cases from the sender to the receiver, and the processing actions are encapsulated

in recent years, with the expansion of the design business of Daqing Oilfield Engineering Co., Ltd., the design tasks of designers have become increasingly heavy, and the management of the design process has become increasingly difficult with the increase of design tasks. In order to build an international engineering company, improve design efficiency and create greater economic benefits, the balcony board does not need to be covered with a large area of 3 cm thick extruded board, and the collaborative design ability must be improved. Therefore, a design information integrated management system (PDM) is built in combination with the engineering design management process. In the process of system implementation, the following key technologies are broken through, which lays the foundation for the rapid construction of the system

1 implementation of electronic safe

the electronic safe technology of the system is to separate the file storage from the database. The files are stored in the file server, and the data records are stored in the database. Both the file server and the database ensure the security of the data through permission distribution. The biggest advantage of this technology is to make full use of the network advantages, which not only ensures the rapid transmission of files, but also can quickly query records. The advantage of electronic safe technology is that there is no problem of format conversion. For the life cycle operation of various format files, such as drawings, images, word processing files, and format files of other professional software, it is only necessary to directly activate the interface of the application software in the interface of information management software through the integration of professional application software, or through the general integration, without opening the file format of the database. The database stores pointer records of file life cycle operations, read and write operations, and access permission operations, which are directly related to the state of the file. In this way, the version change of design documents is an update of records in the database, and the version change of the database itself is only the update process of database program functions, and has no impact on the documents stored in the electronic safe. This technology is convenient for file and database backup, and it is convenient to import the whole electronic safe into the CD for storage and backup

the distributed electronic safe technology works based on TCP/IP network protocol. The electronic safe can be set up distributed in the local network (intranet) or on the Internet (Internet). Of course, the electronic safe box distributed through the local network is much safer in technology than the electronic safe box distributed on the Internet

the distributed electronic safe technology can solve the problem of overload of a single server, balance the load of the enterprise network system, improve the security of the network and deal with emergencies. Through the distributed electronic safe configuration tool, documents can be automatically classified into different electronic safes. Documents can be classified according to the classification requirements of projects or document types

2 implementation of version control technology

version control technology is a technology to solve the life cycle process control of various documents generated by computer professional application software in the design process. The version model of the system mainly divides the document life cycle process into five life states: registration state, login state, login state, release state and obsolete state. In the operation of controlling the whole document life cycle, the document is registered, logged in, logged out, approved for release and frozen, and fully supports version models such as linear version structure, tree version structure and directed acyclic diagram structure. The security control technology of file object, user and version is adopted to facilitate the collaborative development of team members and realize the process of collaborative design

3 realization of process management

in the production and business activities of the enterprise, all departments and personnel complete all kinds of work. According to these works, the microcomputer controlled bolt tension and torsion experimental machine can detect the properties and results of torque, maximum torque, yield point torque, torsional strength, axial force and the relationship with other works in real time. They can be divided into various workflow. In these work processes, various product data are generated or improved, so process management is an important part of PDM system. The quality of process management is directly related to whether a PDM system can operate efficiently and accurately before the enterprise opens, which is the key factor to improve the efficiency of PDM system management

(1) process monitoring simulation technology. Process dynamic monitoring means that the working process and quality monitoring are carried out synchronously. At the control points where quality records need to be left, the program automatically prompts, which meets the implementation requirements of ISO quality system. The system adopts process monitoring technology, which can monitor the progress of the process on the network at any time, control and monitor the process, and count the running quality of a workflow. Process simulation technology can make the released process be verified before formal implementation, and avoid the release of wrong processes and the delay of information transmission

(2) implementation of workflow. In order to realize the electronization of the process, the system introduces the concept of things. Transactions can be defined as a sequence of operations, and things can be divided into top-level things and nested things. Corresponding to the process management in PDM system, the top-level things are the process initiation links in the process, and the nested things correspond to the intermediate links in the process. In order to process and use conveniently, the system establishes a tree processing model

in the development process of workflow management subsystem, the object-oriented development method is adopted, the process of designing business is abstracted as an entity superclass, and every step in the process can be abstracted into use cases from the sender to the receiver, and the processing action is encapsulated

in order to be consistent with the design information integrated management system, the whole module of workflow management subsystem is composed of database, kernel layer, function layer and interface layer. The database is SQL Server 2005; The kernel layer is the operation of the database. In this layer, it is encapsulated into a standard DLL for the upper layer to call; The function layer realizes the function of the process module by calling the kernel layer. In this layer, it is encapsulated into COM components, which is convenient for the interface layer to use different languages to call; The interface layer is the place where the system deals with users. It provides users with a friendly human-computer interaction interface. It adopts the visual 2005 platform and uses c# language for development

4 implementation of system interface technology

the system adopts the latest component (COM/DCOM/com+) interface technology to ensure an open user programming interface. The software developed by using component interface technology can realize the concept of software factory, standardize the interfaces between different software, and users can easily connect different software interfaces

the system adopts dual interface technology, supports the secondary development of com (component object model) bottom layer, and also supports the use of simple and easy to learn programming tools vb, VBA Net platform

system, which will become a perfect choice for controlling gas and liquid flow distribution. The open interface of the object-oriented layer is pdmcom (product data management component object model) interface. Through this interface, secondary development can be carried out, and different software function programs can be compiled by using object-oriented method. Users directly face the problem domain objects of the enterprise without caring about specific database operations. (end)
