Definitions
- the invention relates to a method for improving the accuracy of targeted by infrared and video early fire detection controlled extinguishing systems with a first IR / video camera system for the first detection for continuous fire detection and a second IR / video camera system for the second detection for the automatic Zielnach arrangement to the fire, as well as one with the second detection rigidly connected extinguishing.
- infrared detectors in particular infrared cameras and video cameras for early fire detection in waste incineration plants, recycling plants, outdoor storage and the like are used. This makes it possible to detect fires in the development phase and report them to a downstream fire alarm system.
- extinguishing monitors also known as extinguishing cannons or fire extinguishers - accurately apply extinguishing agents on a fire origin.
- the EP 2 705 881 A1 shows a device for controlling extinguishing media throwers by means of a controller and has a position table, which geometrically maps the target positions of the extinguishing agent.
- the position panel preferably consists of a pressure-sensitive touchpad or a computer-based intelligent tablet PC, wherein the position table is labeled or printed with the geometric target areas of the delete monitor, for example with a sketch of the deleted object.
- the disclosure DE 10 2006 025 286 B3 a device for recording large-area thermal images on a monitor with a thermal camera in a pivoting housing.
- a real-time synchronization of the camera position and the real-time thermal image takes place by synchronization of the camera drive with the camera signal, with the camera moving in real time according to the set scanning speed over the space to be detected.
- the scanned individual images are joined together on the monitor to form an overall thermal image and continuously updated.
- Fig. 1 shows the schematic arrangement of an infrared / video camera controlled launcher extinguishing system.
- a first IR / video camera-1 normally detects the area to be monitored. This is shown here schematically as a surface. But it could also be a complicated, spatial arrangement to be monitored. For example, a football stadium, which is detected by an infrared camera, which is attached to the hanging display block in the center of the stadium. In this case, a hemisphere space would be detected.
- This area can either be detected by optics designed especially for spatial requirements, ie optics that designate a room with a special 180 ° optics - also referred to as hemispherical space detection - or by scanning camera systems consisting of individual images or Composed composite images as a panoramic image capture the surveillance area and put together.
- optics designed especially for spatial requirements ie optics that designate a room with a special 180 ° optics - also referred to as hemispherical space detection - or by scanning camera systems consisting of individual images or Composed composite images as a panoramic image capture the surveillance area and put together.
- Fig. 2 shows an example of a composite IR image of a recycling hall for recycling material, which covers a space of approx. 80 x 30m from a height of approx. 20m.
- the wide-angle effect - also called fish eye - to recognize. This generates in particular distortions with lower geometric resolution in the edge region. Therefore, even with this simple geometric detection range, there are resolution errors that degrade controlling a fire monitor in some areas by up to about 4 degrees.
- Fig. 3 shows the most commonly used motion control of a fire extinguisher. This is composed of a rotational movement of up to 360 ° and a tilt movement of up to +/- 90 ° to the horizontal.
- the best result is a precision of +/- 8 ° x 0.9m, thus an approximate accuracy of + / - 7m. That corresponds to a hit inaccuracy range of altogether 14m.
- Attempts are currently being made to improve these meeting inaccuracies by means of deletion attempts and the resulting angle correction values. However, this requires several deletion attempts.
- a first hit profile is recorded via deletion attempts.
- the calculated correction values are checked with a second deletion test series.
- this approximation method does not ensure that the entire system is damaged by aging, mechanical drift due to constant pressure changes to the overall system or due to errors in the electronics is not changed in its accuracy of impact.
- the method according to the invention makes it possible to precisely set video / infrared-controlled extinguishing systems with regard to the aiming accuracy at detected fire sources and to fight fires as fast as possible, ie already in the formation phase, with as little extinguishing agent as possible.
- time is saved in the fight against the fire, since the targeted extinguishing the maximum amount of extinguishing agent is applied to the fire.
- the environment is protected because the extinguishing water admixed wetting and foaming agents are harmful and sometimes toxic to the environment.
- with a lower consumption of extinguishing agent and a lower storage of extinguishing agent is needed.
- Fig. 1 are a monitoring area U, in which a source of fire G could arise in a room with a ceiling R shown.
- Two IR / video camera systems (hereinafter referred to as Detection-1 and Detection-2, respectively) are used to improve the aiming accuracy.
- Detection-1 D1 is responsible for continuous fire detection.
- the coarse coordinates for the alignment of a fire extinguisher A are calculated. However, these are very inaccurate due to the conditions described above.
- Detection-1 D1 and the extinguisher A are attached to the ceiling R.
- the horizontal deviation F1 of the extinguishing agent jet F to the center M of the detection region E can be easily determined. Due to the rigid coupling between extinguisher A and detection-2 long-term drift is almost impossible. Therefore, a readjustment can be dispensed with.
- the width of the horizontal angle range ie the width of the detected fire hearth G over which the extinguisher A must be moved in order to completely extinguish the source of fire G, can be determined via the detector 2 rigidly connected to the extinguisher A.
- the inclination of the extinguisher A can be calculated from a once empirically determined trajectory.
- the extinguishing spotlight A is set so that it is aligned to the theoretically maximum for the application range necessary throw.
- the throw distance deviation between the actual and setpoint values can be determined. From this it is possible to calculate the real throwing parabola. If an inclination range is controlled instead of a calculated inclination angle, occurring pressure fluctuations and fluctuations of the extinguishing agent composition are compensated.
- the distance J of the extinguishing agent outlet of the extinguisher A to the fire G is not known, the distance J must be determined become.
- no IR / video camera system provides useful distance information to the detected source of fire.
- Triangulation is a geometrical method of optical distance measurement by accurate measurement of the angles ⁇ and ⁇ within triangles or reference lines Z. The calculation is carried out by means of trigonometric functions.
- Fig. 5 and 6 also show the optional possibility of using a marking laser L which rectilinearly marks the center of the detection zone E of the detection-2 D2. With E1 here only the vertical portion of the detection range of the detection-2 D2 is shown.
