Description

Description
The invention relates to a method for controlling extinguishers having a control unit for controlling the extinguishers and a position panel which geometrically represents the actual target positions of the extinguishing agent.
Different sensor systems are known which can detect a fire. Furthermore, there are various extinguishing systems with which fires in industrial plants or larger areas are extinguished. Usually, a fire is detected and an extinguishing system is switched on which sprays or floods a large quantity of extinguishing agent, for example water, into the fire area and therefore extinguishes the fire. Of greater significance is the detection of a fire. This occurs in particular by means of thermal difference detectors, flue gas fire detectors, smoke extraction systems, flame detectors, infrared detectors (pyrometers) or infrared cameras.
In particular, sprinkler systems, considerably more effective deluge systems, and manually controlled fire monitors are used as extinguishing systems. The latter are also referred to as water cannons or deluge guns.
Presently, extinguishers - also referred to as "fire monitors" - are moved into their target extinguishing position by means of mechanical or electronic control units. Among other things, the following control units or operating systems are known: 1. Joystick control:
The joystick is usually moved left or right in order to move the fire monitor around its rotational axis in the clockwise direction or anticlockwise direction. The joystick is moved forwards or backwards in order to set the ejection distance of the extinguishing agent. 2. Feedback control unit:
The position of the extinguisher always corresponds to the position of the control handle. A requirement for this is a basic positioning of the control handle to cover the position of the extinguisher. In this case, the user can always retrace the position of the extinguisher via the control handle.
It is disadvantageous with these solutions according to prior art that the alignment of the extinguisher by means of the described control options always requires visual contact with the target.
When the control unit is rotated relative to the alignment of the fire monitor, the control of the fire monitor requires a high level of skill and spatial thinking of the operator. Since these control units are mostly implemented to be mobile, for example by means of a cable or radio connection, there are therefore often problems with urgent extinguishing tasks.
In addition, the rotational direction of the fire monitor (Pos.l according to Fig. A) changes when the 0° and 180° axis exceeds its direction of movement. A left position of the joystick according to Fig. A leads from these angles to an alignment of the fire monitor (Pos.2 according to Fig. A) to the right, whenever this is assembled to be standing or hanging.
An extinguisher control unit for mobile and stationary water/foam extinguishers is known from DE 196 01 282 Cl, wherein the extinguisher pipe is automatically aligned horizontally and vertically with the fire without a control lever or prevents the extinguisher tube from bumping against outside obstacles located in the field of use, such as, for example, pipelines, underpasses, door posts, cables, branches, etc., on the journey or during use. Here, the extinguisher has a laser measuring thermometer infrared objective control device.
Furthermore, WO 2004/052466 A1 discloses a fire extinguishing system which works with previously formed frequency video images of the surface to be controlled which are compared to the current video-monitored surface and, when a fire is detected, indicates the fire to the person monitoring the system.
The object of the invention is to create a method for controlling fire monitors of the type referred to at the beginning, which allow a comfortable and secure control of extinguishers.
It must be noted that the term "fire monitor" is to be equated to the term "fire extinguisher".
According to the invention, the object is solved in that the data for target alignment are calculated by inputting the geometric basic data, such as the extinguisher outlet height with respect to the object to be extinguished, the ejection characteristics of the extinguisher and the pressure and the extinguisher outlet speed of the extinguishing agent when exiting the extinguisher on the basis of extinguishing tests on site by mathematical calculation in a computing unit connected to or integrated into the position panel.
The direct target position specification can occur by means of an input medium on the position panel, for example a finger of the device operator, and enables a direct alignment of the fire monitor to the source of the fire in the event of a fire. This saves time and enables a quicker extinguishing of the actual source of the fire.
An automatic extinguishing of the fire is possible due to development of the position panel with a unit for intelligent analysis of infrared/live video images for fire analysis by means of suitable hardware and software. Therefore, the possibility exists at any time for a user, for example a fire fighter, to actively and subjectively correct an automatic extinguishing via the panel.
In particular, if the position panel is formed as an intelligent tablet PC, the graphical interface of the position panel can be adapted to the geometric target areas of the fire monitor and/or the extinguishing geometry of the extinguisher. A computing unit is connected to the position panel or is integrated into this. A live video image or a live thermal image is generated by means of a detection unit which is connected to the computing unit.
Infrared and/or video cameras are provided as a detection unit.
Additionally, it is possible to depict an actual representation, for example a photograph or thermal image, of the object to be extinguished on the input surface of the position panel instead of the geometric target areas of the fire monitor.
Furthermore, the position panel can be connected to a unit for intelligent analysis of infrared/live video images for fire analysis by means of suitable hardware and software .
If an infrared camera is used as a detection unit, then it also enables the user of the extinguisher to strike the source of the fire exactly if the space already completely prevents visual contact for the operator due to smoke. Furthermore, it has the advantage that a fire can also be extinguished via remote control, for example from a fire department monitoring centre. In addition, there is the advantage of monitoring the success of extinguishing via the infrared camera.
If a unit is connected as a display of the object to be extinguished on the input surface of the position panel, said unit generating a live video image and/or a live infrared image, the target positions of the extinguishing agent are detected by means of the unit.
By connecting further detection units, infrared and/or video cameras as well as further extinguishers with their control units to the computing unit, it is possible to control several extinguishers using only one position panel. A larger object can hereby be monitored with regard to fire and actively extinguished using only one position panel. The position panel furthermore offers the possibility of checking the success of extinguishing of a larger object.
According to one development of the method according to the invention, the data for target alignment of the fire monitor connected to the position panel are calculated mathematically by a few short "extinguishing tests" on site via the computing unit for the complete extinguishing area, by all possible positions achievable with the extinguisher being calculated from the results of the achieved target positions by the extinguishing agent with the extinguisher alignment of the fire monitor associated with each "extinguishing test".
If the position panel is fed via the computing unit with distance data from a distance sensor, the target parameters of the extinguisher can be adapted mathematically to changing position heights of the object to be extinguished.
It is understood that the features referred to above and further explained below are applicable not only in the respectively specified combination, but also in other combinations or alone, without leaving the scope of the present invention.
The concept of the invention is described in more detail in the description below by means of an exemplary embodiment which is depicted in the drawing. Here is shown:
Fig. 1 a device for controlling a fire monitor.
The device consists firstly of a position panel 1 which is connected to a computing unit 2 for intelligent analysis of infrared/video images for fire analysis by means of suitable hardware and software. A fire monitor 3 is connected to the computing unit 2 via an extinguisher control unit 4 for the extinguishing agent 5. Furthermore, a distance sensor 6 and an infrared and/or video camera 7 are connected to the computing unit 2. The extinguishing agent 5 is guided to a target position 8 of an extinguishing object 9 in the event of a fire.
