Starting from the design review of fire protection drawings, the engineering information tree of the construction project is established according to the management of project approval, material use, construction tracking, acceptance and maintenance, taking the qualified data of fire protection design drawings as the main line of the project, and all relevant fire protection information involved in the whole project is managed in an integrated way.
5 the choice of system architecture and development language
5. 1 database selection
The choice of database development platform is related to a series of problems such as operation efficiency, maintenance, expansion and security. Relational databases are usually used to process data with linear structure. It organizes data in the form of table structure, which is convenient and flexible to handle tables and easy to learn and use, so it is widely used. Microsoft SQL Server is a distributed relational database management system, which uses the SQL language of Transact-sql to transfer the client's request and the server's processing results between the client and the server. Through comprehensive Web support, it provides the core support for Extensible Markup Language (XML) and the ability to query on the Internet and outside the firewall. Considering the characteristics of fire safety management integrated information system and the rapid development of computer and network hardware, SQLServer is used as the platform of database information system, which can fully meet the needs of database use.
5.2 Selection of development language
The system was developed by ASP.net of Microsoft. Adopt MicrosoftVisualStudio development platform; The system development mode is MVC mode. ASP.net is a programming model for creating Web-based applications. VisualStudio.net development platform is efficient and fast, and can provide a visual and object-oriented development environment. MVC architecture is a new development model provided by ASP.net in the new version. Developers can use MVC design pattern to build Web applications and realize clear concept separation (UI or view is separated from business application logic, and application logic is separated from back-end data). The system uses ASP.net language, which can not only meet the needs of adapting and mastering data well, but also develop a beautiful interface, and realize data management and page dynamic update through background technology.
5.3 System architecture
According to the data information processing and requirements of each stage of fire engineering safety management, the system is designed in different levels and functions, taking into account the inheritance and expansibility, and considering the current development of computer technology, improving the work efficiency as much as possible, and adopting the browser/server (B/S) mode. Its structure consists of browser, Web server+middleware and database server. In this mode of system, all data are stored and operated in the server database, and the client sends a request to the server using IE browser and returns the query result immediately, as shown in Figure 3. Database structure design should not only meet the special requirements of the network, but also consider the security and confidentiality of the runtime. The system is a multi-user application system, and users can make online inquiries according to their own rights and uses. All the basic data are stored in the data server, and users can directly operate the database according to their own rights and requirements to achieve the purpose of query. At the same time, the load capacity of the server is also one of the problems that need attention. The system is designed according to the fact that the number of concurrent network connections reaches 100000, the service response time is less than 4 s, and the server cluster processing capacity is not less than 890 100tpmC. System data consists of static data and dynamic data. Static data mainly includes organization information, product information, personnel information and engineering information. Dynamic data consists of 3G network technology, fingerprint collection technology, bar code scanning technology and GPS global positioning technology, which is used to locate fire engineering technical service personnel at the fire engineering construction site and collect fire products in real time.
