Design And Implementation Of Fire Graphics System Based On Linux

In recent years, emergency fire is often happened in high-rise building in various provinces of China. Both personal and financial security are posed a great threat. There are two main reasons: first, complex structures of high-rise buildings, and people are crowded; second, poor real-time performance, difficult judge for the source of fire and other defects are existing in current Fire Control System. Therefore, this is a major problem how can the Fire Control System locates the source of fire quickly and accurately, and then show firefighters visually.To solve these problems, this paper designs a Fire Control Graphics System Software which is based on Linux operating system. The software is based on the traditional Fire Control System and combined the domestic latest trends. The system is developed by Qt library and integrated tools Qt Creator, the system demand is support by MySQL database, serial communication technology, and multi-threading technology.In this paper, a Fire Control Graphics System is analyzed, designed and implemented totally, the paper uses SVG vector as fire architectural plan and adds fire-fighting elements to achieve real-time monitoring of the fire building. The system is connected with fire control controllers and fire equipment by serial-port. Fire control controller sends such as fire and default information to real-time transmission module by serial-port. The system resolves information, the fire location and time information is displayed in the window of fire, relevant fire equipment icon on fire architectural plan makes animation effect to achieve positioning, and the data tables are operated to store the information. At the same time, the system develops the remote monitoring center module, if necessary we can achieve communication with system by serial-port, to complete the further processing of various fire protection information.Tests of the Fire Control Graphics System show that various needs of the fire control are fulfilled properly, the reliability of the system can be guaranteed, it is very easy to achieve further expansion. Thus the initial design goals of this system are achieved well.
