Definitions

  • the present invention relates to a surveillance system for the early detection of fires, whose obvious purpose is to detect possible sources of fire based on the detection of temperature changes produced or originated in the area where the system is implanted.
  • the system basically comprises one or several automated surveillance posts - in which the means for detecting thermal changes are found - an alarm management center and one or several control posts, all these elements being interconnected by means of a communication system .
  • the system is applicable as a means of fire detection and detection, both in forest, industrial, commercial, etc. environments.
  • thermometric cameras allow the detection of heat sources in open environments. They are based on threshold detectors, presenting the typical problems related to them - the low probability of detection or high probability of false alarm, depending on the threshold level selected -, which entails the need for continuous supervision by an operator .
  • thermal cable whose principle of operation is based on its deterioration against high temperatures, which is its main drawback, being a single use.
  • the system of the invention is based on a series of automated surveillance posts and interconnected with an alarm management center, by means of a communications system; with the particularity that; each of these surveillance posts includes: thermal sensors in the infrared wavelength range; a detection unit, and a surveillance unit as visual support by remote control.
  • the thermal sensors are strategically placed to cover large areas of land, being planned to detect the smallest changes in temperature, and may or may not be motorized, depending on the area to be covered.
  • the detection unit is intended to process the radiometric images provided by the thermal sensors, performing an analysis and classification of the heat sources, for later interpretation by other means and thus establishing the type of alarm to be transmitted. in each case, allowing to discard false alarms generated by heat sources not susceptible to causing fires.
  • the classification and processing in the surveillance post itself constitutes one of the most innovative aspects of the system, since it allows minimizing the flow of data to be transmitted to the alarm management unit and, ultimately, to the control posts. This translates into considerable savings in the cost of data transport.

Abstract

Le système est constitué d'une série de postes de surveillance (1) automatisés et interconnectés, au moyen d'un système de communication (4), présentant une centrale de gestion des alarmes (2), comprenant en outre des centres de contrôle et de surveillance (3) connectés au moyen du système ou du réseau de communication (4), avec les postes de surveillance (1) et la centrale de gestion d'alarmes (2). Grâce à des capteurs thermiques (5) prévus dans les postes de surveillance (1), on détecte les changements de température les plus minimes pour qu'une unité de détection (6) de chaque poste de surveillance (1) traite les images radiométriques, les analyse et les classe en vue de leur interprétation postérieure et de la détermination du type d'alarme générée dans chaque cas. L'invention est caractérisée en ce que la centrale de gestion des alarmes (2) reçoit et classe les alarmes, vérifiant si celles-ci doivent être représentées ou non dans un système d'information géographique (9) établi dans les centres de contrôle et de surveillance (3), de manière à fournir des données permettant de connaître s'il existe ou non des foyers d'incendie dans la zone couverte par la système.
