Underground space fire intelligent detection early alarming and forecasting method and apparatus

Abstract

The invention discloses a method for intelligently detecting, early warning and forecasting a fire in an underground space and a device using the method comprising a fire signal detector, an analog-to-digital converter, a data manager, a monitor, a CCD camera, a signal transfer device, a fire alarm control unit, a digital-to-analog converter, a warning device and an underground space ventilation and heat exchange measuring device, wherein the fire signal detector transfers a detected signal to the data manager via the analog-to-digital converter, the information is processed by the data manager and is transferred to the fire alarm control unit via the signal transfer device, and is transferred to the warning device via the digital-to-analog converter, and the data manager processes the information and displays the processed information on the monitor; the CCD camera is connected with the monitor; the underground space ventilation and heat exchange measuring device transfers the information to the data manager. The method and the device adopt a plurality of fire detectors to detect a fire so as to improve an accuracy of a system, return a forecasted result to the system, and use a self-learning capability of a support vector machine to realize high fault tolerance and intellectualization of the system.

Description

technical field [0001] The invention belongs to the field of early warning and forecasting of fires, and in particular relates to a method and device for intelligent detection, early warning and forecasting of fires in underground spaces. Background technique [0002] With the development of my country's economic construction, the use of various underground spaces is becoming more and more common. The particularity of the underground space makes its fire safety very important. Because the periphery of various underground spaces is soil or rock, there is only an internal space, and there are few holes and small areas to communicate with the outside world. When a fire occurs, the smoke exhaust ability is poor, the visibility is low, the internal temperature rises rapidly, the high temperature and high heat are fully burned, and flashover may occur earlier. The combustion rate of fuel in the underground space is three times that of the open space, and the temperature can be a...
