Graphic display method used in fire control room alarm system

Abstract

The invention discloses a graphic display method used in a fire control room alarm system, and belongs to the technical field of fire control. The method is characterized in that the method comprises the steps: based on a cross-platform Qt software tool, adopting a combination mode of defining a view, setting a scene and loading primitive items to import and display a building plane vector diagram in an svg format; developing a random bean scattering mode, and importing a plurality of fire detector component diagrams in the formats of png, ico, jpg and the like into a building layout diagram at a time; customizing a method for dragging an arrowhead evacuation line in any direction by a mouse, so that engineers are assisted to realize rapid self-defined evacuation route arrangement on the building plane vector diagram. The method is suitable for the ever-increasing fire-fighting alarm requirement, and along with the rapid development of the instrument and industrial control automation graphic display technology, the related new technical method adopts cross-platform Qt software development, and adopts an svg format vector diagram supporting various operating systems to replace limited wmf format input.

Description

technical field [0001] The invention belongs to the technical field of fire protection; specifically, it relates to a graphic display method used in an alarm system of a fire control room. Background technique [0002] In recent years, with the rapid development of housing, large commercial plazas, hospitals, schools and other real estate markets, the demand for fire alarm systems is increasing; especially in the case of tight land resources, developers have to improve land utilization efficiency and ensure fire safety , Buildings present a trend of high number of floors, subdivision of internal structure, and diversification of fire detectors. Fire safety is urgent and mandatory, and on-site delivery engineers need to efficiently complete the following tasks: import and clearly display the floor plan of each floor, the accurate layout position matching smoke and temperature and other fire detector component diagrams, evacuation and escape route diagrams, The combined locat...

Problems solved by technology

[0003] However, most of the existing fire control room alarm systems use the MFC framework of the windows system, and the way of loading and displaying graphics used is a technical means more than ten years ago. It can only be run with a simple floor plan and a small number of components. Once it is faced with a multi-layered and complex building floor plan and more than a thousand detector component maps are loaded, the operation efficiency is low, and there will be zooming in, zooming out, and dragging and moving. and screen flicker
