Definitions
- the invention relates to methods and devices for detecting fire, in particular for the early detection of forest fires.
- the term "forest” shall generally be used to denote, in general and for simplicity, any external environment containing vegetation that may burn, it being understood that the designation “trees” of the said forest includes for the purposes of the present application, plants of any size and of any kind.
- Another commonly used method is to visually monitor a wooded area from a viewing point that is usually placed high.
- This solution is also expensive in terms of human resources, since to cover a large area, you need several observation points, and for each observation point, a team of agents who take turns to monitor the forest with the binoculars.
- detection of a fumarole it is then necessary to send someone on the suspect zone, to check if it is indeed a beginning of fire.
- This verification and confirmation process is time consuming because it is not easy to pinpoint the area of probable start of fire. If the fire is out and there is wind, valuable time may be lost before the actual start of the fire and the actual mobilization of the means of fighting the fire.
- An object of the invention is therefore to provide a method and a device for detecting forest fires without the disadvantages of known methods.
- Another object of the invention is to provide a method and an automated fire detection and monitoring device, to limit to a minimum the human interventions in the monitoring phase and detection of the beginning of fire.
- Another object of the invention is to propose a method and a fire detection device which makes it possible to detect a fire start very quickly, and also to locate it with great precision, which makes it possible to direct on the spot very quickly. the first means of intervention.
- Another object of the invention is to provide a method and a fire detection device capable of following in real time the spread of a forest fire after starting, including at night.
- the subject of the invention is an early detection system for a forest fire departure, characterized in that it comprises a a plurality of sensors constituting a mesh of the forest area to be monitored, each sensor being able to locally detect a start of fire, and being associated with a radiofrequency transmitter connected by radio to a control station or terminal, so that the detection of a fire departure near a sensor is automatically transmitted to the control terminal, which generates an alert signal, especially for firefighters.
- each sensor and / or each control terminal is associated with positioning information, in particular of GPS ("Global Positioning System”) type, and each sensor periodically transmits an identification signal towards the control terminal, so that the absence of an identification signal is interpreted as a probable start of fire at the location of the sensor or near the control terminal.
- GPS Global Positioning System
- control unit is configured to emit an alarm signal only in the event of simultaneous absence of the identification signal from two or more neighboring fire sensors.
- each sensor comprises an antenna made of a material which deteriorates above a predetermined temperature threshold, so that the temperature rise in the vicinity of the sensor above the predetermined temperature threshold.
- predetermined threshold causes the disappearance or the deterioration of the antenna and the impossibility for the sensor to communicate with its control terminal.
- each sensor is sensitive to a gaseous component representative of a start of fire, so that when the concentration of said gas component exceeds a predetermined threshold in the vicinity of a sensor, this sensor sends an alert signal to the control terminal.
- the system's sensors are located in the trees, about halfway up the trees.
- FIG. 1 illustrates a block diagram of the detection system according to the invention.
- FIG. 2 illustrates a block diagram of a sensor used in the detection system of FIG. 1.
- This system 1 comprises on the one hand a plurality of sensors 3 able to detect the evolution of a physical or chemical quantity whose sudden variation is able to indicate a start of fire.
- This network of sensors 3 constitutes a mesh of the forest area to be monitored, with a density, that is to say a number of sensors per unit area, which the skilled person will be able to determine on a case by case basis. , in particular depending on the recurrent risk of fire starts in the area to be protected, or the usual climatic conditions in the area.
- the choice of the density of the sensor network is a compromise between the cost of the system which increases with the number of sensors, and the environmental conditions of the area to be protected.
- the density of the sensor network will have to be higher in a rather dry wooded area often exposed to high winds, such as the South of France or Portugal, and it may be lower in an area. more northern woodland.
- a system of detection according to the invention is already very effective as soon as it comprises between 3 and 5 sensors per hectare of forest, the network being for example constituted of square meshes comprising a sensor at each corner of a square, and a control terminal at center of a mesh.
- each sensor 3 is associated with a radiofrequency transmitter 7 preferably connected by radiofrequency to a neighboring control terminal 5, so that the detection of a fire departure near a sensor 3 is automatically transmitted to the control terminal, which then generates a long-range radiofrequency warning signal, especially for firefighters.
- each sensor 3 In order to obtain the finest granularity possible, it would be possible to provide each sensor 3 with long-range radiofrequency transmission means, so that each sensor would itself be able to directly alert the firefighters in the event of detection of fire start. This solution would however be quite expensive.
- a preferred variant of the invention is that in which the sensors 3 have a radiofrequency range of the order of 50 to 100 meters, sufficient to transmit an identification and warning signal to a control terminal 5 located in the center of the sensor mesh considered.
- each sensor 3 comprises a unique identification, which is associated with positioning information of the sensor (or of the nearest control terminal), in particular of the GPS type ( "Global Positioning System").
- GPS type "Global Positioning System”
- each sensor 3 transmits by radio information including its identification number, and a database makes it possible to link the identification of each sensor, and its geographical location.
- each sensor does not transmit continuously, but transmits a periodic identification signal, so that the absence of an identification signal for a period greater than one or a few periods of the signal, be interpreted as a start of fire at the location of the sensor.
- each control terminal is configured to emit an alarm signal only in the event of the simultaneous absence of an idenfication signal of two or several neighboring fire sensors. Since the probability that two or more neighboring sensors will simultaneously fail is small, this almost simultaneous failure or in a short time interval will make it possible to determine with very little error that the origin of the absence of a signal is in fact a departure. of fire.
- Each sensor 3 comprises an electronic circuit (not shown) powered by a battery calculated for an autonomy of several years, which supplies a memory circuit associated with a radio frequency transmitter 7.
- the memory circuit enables the storage of the GPS location information of the sensor 3 during his installation. This information is converted into an analog signal by a digital-to-analog converter, which at the output delivers the analog signal to an antenna 11.
- the electronic circuit comprises a simple logic circuit which receives as input the information of temperature from a stage 9 providing the temperature sensor function, and when the temperature is detected as having passed above a certain predetermined threshold, for example 70 ° C, the logic circuit controls the end of the transmission of the radio signal for the control terminal 5, which corresponds to the detection of a fire departure.
- a certain predetermined threshold for example 70 ° C
- the antenna 11 is made of a material which deteriorates above a predetermined temperature threshold.
- the rise in temperature near the fire sensor 3 above the predetermined threshold results in the disappearance or the deterioration of the antenna 11 and the impossibility for the sensor 3 to communicate with the associated control terminal, which which will be interpreted by the control terminal and downstream elements, as a start of fire.
- each sensor 3 can be designed to be sensitive to a gaseous component representative of a start of fire, such as terpene, so that when the concentration of said gaseous component exceeds a predetermined threshold in the vicinity of a sensor 3 , this sensor sends an alert signal to the associated control terminal which relays it to the fire department.
- a gaseous component representative of a start of fire such as terpene
- the invention makes it possible to detect automatically, and almost in real time, the start of a forest fire.
- the system is easily adjustable, especially by playing on the density of the implantation of the sensors, to obtain a more or less rapid detection of a fire departure.
- the regrouping and the computer monitoring of the signals of presence and the absence of sensors makes it possible to follow in real time the evolution of a proven fire, including at night, which allows a better management of the means of fight fireproof.
- real-time monitoring makes it possible to quickly detect a change in the spread of the fire, which makes it possible to position firefighters with maximum safety.
