FIRESENSE - monitoring centre
The system developed in FIRESENSE makes use of innovative technologies for early detection and response to fire. The system is capable of generating automatic warning signals for local authorities whenever a dangerous situation arises, as well as displaying the predicted fire propagation. The innovation is mainly based on the way data is collected (multi-sensor surveillance technologies) and processed (detection algorithms). All the sensors of the system send their data to a monitoring centre which provides the Graphic User Interface (GUI).
The data is retrieved from the surveyed field by using optical and infrared cameras, a Wireless Sensors Network (WSN), official weather information services and local meteorological stations. The WSN is deployed in the surveyed area and measures the environment periodically (e.g. ambient temperature and humidity). Optical cameras (visible and IR) monitor not only the site itself, but also the surrounding forested land. Both the camera outputs and the WSN measurements are fused in the control centre for evidence or indications of fire in the monitored area. When fire is detected, the system delivers alert messages for the fire fighting management.
In addition to periodic sensor measurements, specific events that require special attention can be triggered by activity, smoke or heat detection sensors. Moreover, meteorological data received from weather information services and stations deployed in the monitored area are used to create alerts in case of extreme weather conditions.
The centre provides the user with an intuitive graphical interface consisting of three screens: the main screen, the video screen and the maintenance screen. Main and video screens are described below:
The main screen of the Graphic User Interface shows the map of the supervised area and the location of all installed sensors/cameras. It displays several tabs. The most useful is the sensor tab which lists all types of sensors. It is possible to click on a sensor icon to get information about its status, incoming data flow and parameters. By clicking on a camera icon, a small window pops up displaying the real time video captured by that camera.he video screen is dedicated to the cameras. It is composed of two displaying sub-windows. The largest one displays the video stream of the camera selected by the user (in case of an alert). The other displays a video stream matrix of system cameras. Furthermore, the user can monitor the cameras by zooming, tilting or panning given that the cameras feature PTZ (pan-tilt-zoom).The control centre is used to remotely monitor the site and supervise the status of the system.
