Abstract

Fire monitoring system that is constituted by a series of cameras distributed by the rooms to be monitored, whose images are transmitted to be displayed on monitors located in a control center, and that includes a processor in which runs a specific software that monitors in real time the images taken by the cameras and is able to detect in them if fire or smoke is taking place, activating in this case some alarms.

Description

Fire monitoring system.

Object of the invention

The present invention relates to a system of fire monitoring.

Background of the invention

Currently in various buildings or rooms are known fire monitoring systems constituted by a series of sensors, normally detectors of fumes, whose signal generates a warning or alarm, and that may be associated with the activation of automatic extinguishing means, such as water sprinklers.

The problem of this type of facilities is that they require a large number of sensors to cover A certain surface. For example, for a surface diaphanous of about three hundred square meters can be required of 10 to 20 detectors with their corresponding expenses. Also I know requires the assistance of a person to the location where Smoke detected to verify the extent of the incidence, which implies a delay that, in case of severity, can lead to May the spread of fire and damage be much greater.

Description of the invention

The system of the invention serves in an optimal way for fire monitoring with reduced costs compared to the implementation of traditional systems, and with immediacy in the possibility of assessing the severity of the
incidence.

According to the invention, the system it comprises a plurality of cameras, which can be of types various such as video, spectral or multispectral, depending on the requirements distributed by the rooms to be monitored.

The images taken are usually transmitted to a control center, and transmission means may be used miscellaneous: wired by coaxial cable, fiber optic, via radio, etc. There are monitors in the control center where These images will be displayed.

The system also includes a processor, usually a personal computer, that has sufficient power depending on the quantity of images to be processed, and in which there is a specific software that analyzes the images taken by the cameras in real time, discriminating on the mainly the existence of flame or smoke, and additionally the existence of other substances, such as gas or liquids, that show an escape or spill of the corresponding conduits or equipment.
teeth.

Associated with said processor, a warning, usually acoustic and / or luminous, that in case of detecting an incident will generate the corresponding warning, which it can be face-to-face in the same control center and / or remote to through, for example, internal or external telephone networks, etc.

Optionally the processor and the support will be prepared to automatically show the images in which the incidence has been detected in any of the monitors of the control center, so that the scope of the same can be instantly verified. It will also be optionally prepared to act on automatic extinguishing media that cut or extinguish the spread of fire at the same moment of detection.
tion.

Therefore, with a minimum number of cameras cover a larger area than with smoke detectors, especially in diaphanous stays. For example, with a single camera can be displayed, and therefore monitored, a large surface, of the order of hundreds of square meters, with the consequent saving.

Also the use of cameras, monitors and associated specific software will enable the system to prevent against intrusion if the software prepares to detect movements, also generating the relevant notice.

Additionally, the system may include media of storage where the images that will be registered may interest, either directly those of an incident, such as they can also be images taken from time to time but not There is incidence.

Brief description of the drawings

Figure 1 shows a scheme of the system of the invention.

Description of a practical embodiment of the invention

System 1 of the invention is constituted by a series of cameras 2 whose images are shown in a series of monitors 3 located in a control center 4.

The cameras can be fixed or mobile, and of various types: video or spectral. Likewise the images taken may be transmitted to the control center by means diverse, either by coaxial cable, fiber optic, radio link, etc. A wired connection 5 is shown in the figures.

The system includes a processor 6 of the images obtained by using software specific. This processor will usually be a type computer personnel, and through the software will monitor and process the images obtained in real time and continuously, being equally capable of storing them in a suitable medium, such as in a disk drive 7, be it a hard drive, a CD, a DVD or Similary.

The software that runs on the processor is capable to discriminate in the images, for example analyzing their colors or spectra, if a fire is occurring, or if there is smoke in the monitored stays. In this case a warning is generated that can be visual and / or acoustic, by means of a flash generator 8, images or sounds 9. You can also detect the spillage of others  substances such as gases or liquids, and even movements, functioning as a comprehensive surveillance system against various incidents and anti-intrusion.

In addition, the system can display so automatic images taken where the incident has been detected  in some 3rd or all monitors of the control center.

Obviously, and if desired, smoke detection or directly from fire can be associated with the activation of some automatic extinguishing elements, such as water sprinklers or similar, or the generation of a remote notice to third parties (Firefighters, Police, Emergencies, etc.), through a cellular terminal or a modem 10.

Describe sufficiently the nature of the invention, as well as how to perform it in practice, should be noted that the provisions indicated above and represented in the attached drawings are susceptible to modifications of detail as long as they do not alter the principle fundamental.
