First and foremost, PARATRONIC is a French manufacturer engaged since the 90's in the activity of "Natural Risk Management" (rapid floods, landslides,...).
In July 2005, the management of Paratronic decided to develop a camera-based early fire detection system.
Since then, this development has been concretized by the implementation of a camera system of automatic detection of the departures of fires on the forest massifs of the departments of Landesthe Lot et Garonne, of Charente Maritime and ofa part of Var and the Alpes de Haute Provence.
Our expertise in crisis management systems, and in particular our experience in setting up camera-based fire detection and location networks, combined with the professionalism of civil security personnel (Fire and Rescue Services), within the framework of a close partnership, systematically results in a detection and location system that meets the needs of the project owner as closely as possible.
The ADELIE system is based on :
It is therefore a global and integrated solution of a fire monitoring and warning system whose purpose is to detect and locate the beginnings of fires with equipment installed on pylons and other supports (watchtowers, water towers, etc...).
The data collection and presentation system is focused on early detection and location of fire starts, rapid transport of information and the possibility of tracking events.
It also allows to satisfy the information needs of the user service partners without interruption of service.
As this plays an important role in the effectiveness of remote monitoring, particular care has been taken to ensure the ergonomic presentation of the workstations of the monitoring and control centre officers.
In the same way, a particular care was brought to the choice of the proposed materials, guided by the concern of the best quality/price ratio. Thus, all the equipments are in conformity with the standards in force in the field which concern them and profit from the necessary approvals.
ADELIE (Alert, Detection and Localization of Fires) is based on digital images and their computer analysis.
The system allows to :
Each detection site benefits from an installation including the setting up of :
ADELIE is an automatic forest fire detection system capable of rapid detection with minimal false alarms.
Indeed, the ADELIE system allows 360 degree monitoring every 2 minutes and the number of "false alarms" is low enough to allow an operator to manage up to 20 laps.
ADELIE is equipped with an accurate doubt detection system that allows the triangulation of a fire outbreak from the automatic detection images, but also from the doubt detection system (or by mixing the two).
The transmission system allows the routing of all the data necessary for the treatment through an adapted and powerful communication network.
This transmission system sends all the images in real time.
ADELIE is a secure and scalable tool offering a great capacity for parameterization, evolution, ergonomics and user-friendliness. Indeed, it is not an "off-the-shelf" software package, but an open and scalable system, adapting to the needs of users and integrating into the functioning of the Fire and Rescue Services or the forestry administration.
Thus, ADELIE is a location and management tool that offers the possibility of interfacing with geographic information systems, warning systems, digital terrain modeling systems, meteorological systems, etc.
The automatic forest fire detection system ADELIE is based on the principle of image capture and processing with optical coverage from the designated high point to the horizon and over 360 degrees.
The shooting equipment is distributed on the different high points and covers the wooded areas visible from these sites.
The system ensures the detection of fire starts by smoke detection up to a distance of 20km. Smoke detection alerts the monitoring centre where the system operators are located.
The surveillance operators have a software interface to view the images, so they can confirm or deny alarms using the remote controllable doubt camera.
The surveillance center receives continuously and in real time the images taken by the detection cameras and the video delivered by the camera of doubt removal. This organization allows in addition to the automatic detection to have a human video surveillance.
To this end, the operators can control the cameras of doubt removal and visualize the shots of the detection cameras on 360 degrees.
The various elements stored on the computer systems can be transmitted, in the form of export to other computer systems.
A remote access, via SDSL, allows the maintenance and the remote repair of the materials which will be connected there.
The 2 cameras will be clamped to the stem.
Schematic diagram: position of the cameras and the radio antenna.
Weight Cameras :
Weight Radio antenna: will be defined according to the propagation study which will be carried out during the detailed technical study. Estimated weight of the antenna with its mounting bracket: 4Kg
Other types of transmission media can be studied: Fibre optics, SDSL, etc...
Weight: The dimensions and the weight of the jib depend obviously on the sites to be equipped with the means of fixing usable on the towers to be equipped. In general, the weight of this system is limited to less than 10kg.
The total weight (stem, cameras, radio, ...) is therefore generally less than 50kg.
360 degree coverage and zoom. Continuous 360-degree rotation and 36x Pan/Tilt/Zoom functionality, ensuring maximum coverage area.
The speed of the Pan and Tilt ranges is 300 degrees per second, which allows the camera to be positioned very quickly on a desired area.
Up to 16 positions can be pre-programmed with an accuracy of ±0.2 degrees.
In accordance with the legislation in force, the camera of doubt removal makes it possible to occult certain zones of shooting. In particular, the areas protected by the texts concerning video surveillance on the public highway and in places open to the public.
This function allows unwanted or prohibited areas to be masked to prevent invasion of privacy. The masking function locks out designated areas even when the PTZ mode is activated, using three-dimensional recognition of the camera's position based on PTZ movements.
Up to 8 masks can be configured using the Zone Masking Tool, which is included on the version 1.1 software CD-ROM.
Image processing, file generation, file and image sending:
Equipment of the central station of control and command of the cameras.
On this same screen, a function allows, in case of night detection, to display the corresponding daytime image in order to give a context to the fire start.
In order to avoid the detection of known smoke (factories, firebreaks,...), it is possible, on each photo, to draw "exclusion zones".
This is the area of the picture where a detection does not give rise to an alarm.
The location is done either by automatic triangulation or by "Azimuth/Distance", on a map base that can integrate the ortho-photographs of the region.
The coordinates of the fire are then automatically sent to the different systems of the Fire and Rescue Service: GIS, management software of operational means, etc...
ADELIE servers :
The heart of the system is a set of several algorithms whose performance allows, in normal conditions, to detect smoke up to 20km from the lookout point. Note that the farthest smoke detected was more than 80km from the tower (detection made in favorable weather conditions).
At night, ADELIE detects the lights emanating from the fireplace.
In order to discriminate these lights from industrial or human lights, the ADELIE night algorithm learns from "normal" lights during about 2 months.
For example: Detection of a fire hidden by a curtain of trees on the horizon. Another example: Detection of a ground fire in foggy weather.
Or, night detection with "stray" light discrimination.
