Description

[0001] extinguishing system

[0002] Description

[0003] The invention relates to an extinguishing system with at least one extinguishing agent thrower which is rotatable about a fastening axis by means of at least one motor and is connected to an extinguishing agent line for supplying extinguishing agent, at least one camera which is rotatable about at least one fastening axis by means of at least one motor, an electronic control system which comprises at least one memory unit in which at least basic geometric data of the relevant area and / or data of the extinguishing agent thrower are stored in a readable manner, and a computer module for data processing, an input device connected to the control system for data input and / or for controlling the extinguishing agent thrower and the camera and a screen connected to the control system for displaying images from the camera.

[0004] Extinguishing systems are known, for example, from DE 102016 104349 A1, DE 102011 053 373 A1, and DE 21 2010 000 060 U1 and are increasingly being used to protect waste bunkers and storage facilities, both outdoors and indoors. For fire detection and early fire detection, these predominantly automatic extinguishing systems comprise at least one camera, which is usually mounted on top, for example, on a ceiling or a mast, and is pivoted over the area to be monitored.If a fire source, a smoldering ember, or an area with an unusually high temperature for the material being monitored, indicating a fire incipient, possibly even deeper below the thermographically monitored surface, is detected, these higher-temperature locations, also referred to as hot spots, the control system directs an extinguishing agent dispenser toward this fire source and opens a valve so that the extinguishing agent flows out at a relatively high pressure and in a relatively large quantity. Due to inaccuracies in the detection of the fire source and in the targeting of the extinguishing agent dispenser, the extinguishing agent dispenser is often wasted vertically and / or horizontally in an attempt to extinguish the fire.Precisely positioning the camera and / or the extinguishing agent dispenser proves difficult in practice, as these devices can only be mounted with deviations from an exact vertical position, which can sometimes lead to significant deviations from optimal conditions during swivel movements and when discharging the extinguishing agent to a fire source many meters away from the dispenser. Furthermore, the hydraulic conditions of the extinguishing agent on site, i.e., at the installation location, are often unknown and can only be calculated approximately.

[0005] To control the extinguishing agent dispenser, it is connected to a so-called positioning panel or joystick. If the positioning panel is designed as a tablet, i.e., a computer with a touchscreen, the user sees the images captured by the camera on the display and can mark a target for the extinguishing agent with a simple tap, for example, with a finger or an active stylus, or adjust the extinguishing agent dispenser accordingly if the target is not hit automatically.

[0006] US 2004 / 0 129 434 A1 and CN 20 652 6437 U disclose automatic extinguishing systems with movable IR sensors for detecting the source of a fire and with an extinguishing agent dispenser.

[0007] WO 2004 / 052466 A1 shows another extinguishing system with a fixed

[0008] Camera and a manually controlled extinguishing agent thrower.

[0009] The invention is based on the object of creating an extinguishing system of the type mentioned above that, due to its installation configuration, enables faster data processing with a smaller data volume than the current state of the art. Furthermore, the object of the invention is to carry out firefighting or early fire fighting in such a way that extinguishing agent is delivered in a relatively small amount and in a relatively targeted manner.

[0010] The tasks are solved by aligning the mounting axis of the camera and the mounting axis of the extinguishing agent thrower parallel to each other and by aligning the optical axis of the camera at a defined initial angle to the mounting axis, wherein the initial angle is stored in the memory unit.

[0011] Due to the parallel alignment of the mounting axis of the extinguishing agent turret and the mounting axis of the camera as well as the defined alignment of the camera, the volume of data to be processed by the control system, in particular the image data of the camera, is significantly reduced and an error in the control of the extinguishing agent turret to the detected source of the fire or the recorded and evaluated hot spot in the monitored room is limited to the offset of the extinguishing agent turret to the camera, whereby this error is negligible, especially in view of the volume of extinguishing agent discharged.

[0012] The setting angles as well as the coordinates or positions at which the camera and extinguishing agent dispenser are mounted are stored in the control unit's memory unit. Furthermore, the positioning of the fire monitor—i.e., its alignment with the fire source, the so-called hotspot—can be carried out quickly with reduced computing effort compared to the state of the art. Speed ​​is given higher priority than local errors, which can be corrected, if necessary, by manually adjusting the fire monitor using any input device, or by automatically adjusting the fire monitor or enlarging the extinguishing area based on the camera's feedback that the target has not been hit. The input device could be a joystick, a mouse, or a keyboard, for example.To simplify the control of the extinguishing monitor's adjustment motors, especially in stressful situations, a touchscreen is connected to the control system as an input device and / or screen. The screen displays an image of the camera's area relevant to the extinguishing system. The extinguishing agent dispenser can be manually moved, for example, by an operator of the otherwise self-operating extinguishing system, using their finger to change the impact point of the extinguishing agent displayed on the screen.

[0013] The camera's mounting axis and the extinguisher dispenser's mounting axis are aligned parallel to each other. The camera and extinguisher dispenser can be offset in height, for example, by approximately 1 m, so that the extinguisher dispenser, for example, does not destroy the camera with extinguisher agent. The difference in height is relatively insignificant for actual accuracy.

[0014] Of course, data from the extinguishing agent turret is stored in the memory unit, which can include, for example, standard turret curves determined by the manufacturer.

[0015] The optical axis of the camera is offset by 10° to 170°, preferably by 40° to 50°, particularly preferably by approximately 45° to the mounting axis, but can also be pivoted as desired.

[0016] If a fire source or similar hot spot can be identified in the camera image displayed on the screen, for example by means of an image processing device, the control system calculates the coordinates of this point and controls the motors assigned to the extinguishing agent dispenser in such a way that the extinguishing agent dispenser is aligned in such a way that the extinguishing agent hits exactly the calculated point.

[0017] The camera can be designed as a thermal imaging camera or a video camera with position-determining flame or smoke detection without departing from the scope of the invention. To ensure that fire sources can be clearly identified and distinguished from other hot spots, microphones can be installed in the monitored space, for example, enabling the control system to detect engine noises. The image processing device can also be designed to detect vehicles, so that a hot engine or exhaust of a vehicle is recognized as such and not as a fire source that needs to be extinguished.

[0018] To capture the space to be monitored with the camera as completely as possible, the camera is preferably driven in an oscillating or rotating manner around the mounting axis from a zero position. For example, the camera can be rotated radially by up to 360° around the mounting axis from a zero position. Accordingly, a distorted or relatively circular image is displayed on the screen, which is then assembled and displayed, for example, as described below.

[0019] In order to monitor a larger space, the camera can be rotated from the defined starting angle to the mounting axis by a defined swivel angle in the direction of the mounting axis and a defined swivel angle in the opposite direction. Preferably, at each swivel angle by which the camera is rotated about the mounting axis, a distorted, circular thermal image is created. This has the advantage that a hotspot, for example a source of fire, a developing fire, a smoldering ember, or an area with an unusually high temperature for the material being monitored, which could indicate an incipient fire, possibly even in a deeper area below the thermographically monitored surface, can be detected and marked by the image processing system and spatially assigned to an extinguishing agent dispenser.

[0020] In its design, the camera includes a fisheye lens and the controller outputs a composite image to the screen in real time.

[0021] For power supply, the camera is connected to a power grid via a slip-ring arrangement or inductively. Flexible cables can, of course, also be used without departing from the scope of the invention. The camera conveniently transmits image data to the controller via wired or wireless data transmission. Wireless data transmission, in particular, can be implemented using so-called near-field communication, a wireless LAN, or the Bluetooth standard.

[0022] To simplify the evaluation of the images recorded by the camera and displayed on the screen and evaluated by the image processing device, the camera is designed as a thermal imaging camera and scans the monitored space in continuous pivoting movements in at least one direction, whereby an image processing device of the control system can combine the individual images of the thermal imaging camera to form a spatial image on the screen.

[0023] In one embodiment, a laser coupled to the controller is assigned to the camera and / or the extinguishing agent dispenser, with the laser beam of the laser assigned to the camera being directed toward the camera lens, and the laser beam of the laser assigned to the extinguishing agent dispenser being directed in the direction of the extinguishing agent's exit. Preferably, the laser of the camera and / or the extinguishing agent dispenser is configured for distance measurement and / or for emitting a pulsed laser beam. The distance measurement provides the controller with additional actual data, which is used to calculate the coordinates of the fire source and thus the required impact point of the extinguishing agent, particularly to take into account the trajectory path of the deployed extinguishing agent.The distance data is particularly important when the stored material is relatively high in the area to be monitored, as is the case, for example, with a constantly changing pile of waste in a waste bunker or a stack of tires in a tire depot. This is because the two-dimensional data from the camera image is then supplemented by precise distance data, which ensures a three-dimensional calculation of the target coordinates for the extinguishing agent. Pulsed operation of the laser beam simplifies its unambiguous detection through captured images and their evaluation by the control system, either by the image recognition device or signals from the laser beam detectors.

[0024] It is understood that the features mentioned above and those to be explained below can be used not only in the respective combinations specified, but also in other combinations. The scope of the invention is defined solely by the claims.

[0025] The invention is explained in more detail below using an exemplary embodiment with reference to the accompanying drawing.

[0037] Fig. 12 is a fourth schematic representation of the arrangement according to Fig. 2 and

[0038] Fig. 13 shows a representation of a thermal circuit.

[0039] The room 1 to be monitored is, for example, a storage room for combustible material 2, such as tires, garbage, but also motor vehicles, plastics, or the like. The room 1 is defined in a known manner by the dimensions of its floor area and its height and is usually bounded by a floor 3, side walls 4, and a ceiling 5.

[0040] In order to monitor room 1 for the occurrence of a fire in material 2 and, if necessary, to initiate automatic fire extinguishing, the extinguishing system is installed. This essentially comprises a camera 7 designed as a thermal imaging camera 6 and an extinguishing agent dispenser 8, which can also be referred to as an extinguishing monitor or extinguishing dispenser. The camera 7 and the extinguishing agent dispenser 8 are attached to specific positions on the ceiling 5 of the room in such a way that a mounting axis 17 of the camera 7, which includes, for example, a lens 18 suitable for 24° exposures, is aligned parallel to a mounting axis 19 of the extinguishing agent dispenser 8. The camera 7 can be pivoted in an oscillating manner around the mounting axis 17 by means of a motor 20, in particular a stepper motor, for example, through any desired angle of rotation up to 360°. Furthermore, the camera 7 or its optical axis 21 assumes a defined position relative to the mounting axis 17.If the room 1 to be monitored has special conditions, the camera 7 can be pivoted such that the axis 21 describes a larger or smaller angle to the fastening axis 17 and / or around the fastening axis 17.

[0041] The extinguishing monitor 8 can be pivoted about two axes, as indicated by the arrows 9 assigned to the extinguishing agent thrower 8, namely about its mounting axis 19 and an axis oriented at an angle offset therefrom. The extinguishing agent thrower 8 is connected to pipes or hoses for the extinguishing agent. Furthermore, the extinguishing agent thrower 8 is coupled to an electronic control unit 10, which in this case is designed as a tablet 11 and comprises at least one memory unit 12 for readable storage of data, a computer module 13 for data processing, and a screen designed as a touchscreen 14, wherein the touchscreen 14 serves both as an input unit and for displaying the images recorded by the thermal imaging camera 6, wherein the thermal imaging camera 6 is of course also connected to the tablet 11.

[0042] The storage unit 12 of the electronic control system 10 stores the basic geometric data of room 1, which are measured on-site as actual data. These basic geometric data of room 1 describe the floor area, i.e., the dimensions of floor 3 and the height of room 1. Furthermore, the coordinates to which the camera 7 and the extinguishing agent dispenser 8 are attached are stored. Furthermore, standard dispenser curves determined by the manufacturer, which describe the throw distances of the extinguishing agent under a specific pressure and specified extinguishing agent dispenser settings, as well as various software and image data processing devices 23, can be stored.

[0043] The software and image data processing device 23 ensure, on the one hand, the detection of a fire source 15, in particular by excluding other irrelevant heat sources, and, on the other hand, a display of the images captured by the camera 7, which can be combined to form a representation of the entire room 1. A circular thermal radar image 22 is created as a view on the touchscreen 14, which in this case shows a fire source 15, which can be designated as a hotspot, to which an extinguishing agent dispenser 8 can be directly assigned.

[0044] Furthermore, the tablet 11, in particular its touchscreen 14, can be used by an operator of the extinguishing system to control motors 20 associated with the camera 7 and the extinguishing agent dispenser 8, which are preferably designed as stepper motors, for pivoting the camera 7 and the extinguishing agent dispenser 8. As an alternative to control via the touchscreen 14, a joystick can also be provided as an input device on a computer with an associated screen.

[0045] At least the camera 7 is assigned a laser 16 aligned in the image recording direction, which can be designed for distance measurement and / or for emitting a pulsed laser beam 18.

[0046] The position of the fire source 15 detected by camera 7 can be described with relatively little computational effort, and the extinguishing agent turret 8 can be tracked relatively precisely, since, in particular, the mounting axes 17, 19 on both sides are aligned parallel to one another, so that deviations or errors of minor significance arise from the different mounting points as long as the distance between the extinguishing agent turret 8 and camera 7 is relatively small, for example, up to approximately 5 m, preferably up to approximately 2 m. However, the error is generally so small that the fire can be extinguished at this point with the extinguishing agent. The error corresponds at most to the distance between an axis 21 of camera 7 and a quasi-exit axis of the extinguishing agent turret 8.

[0047] Using the stored actual data and the coordinates of the attachment points, all points in space 1 can be calculated on the controller 10, for example by means of triangulation on the controller, and the extinguishing agent dispenser 8 can be quickly aligned by appropriately controlling the stepper motors assigned to it, so that a fire source 15 can be extinguished, whereby, as an alternative to the stepper motors, any motors 20 with assigned position sensors can also be used.

[0048] During normal or controlled operation, the camera 7 continuously pivots to monitor the entire room 1, specifically around a vertical axis, in particular oscillating, if necessary by up to 360°. The extinguishing agent dispenser 8 is pivoted into a corresponding extinguishing position when a fire source 15 is detected. The thermal radar image 22 is generated on the image processing device 23 based on images recorded by the camera 7 and can be displayed either as a relatively schematic representation, which essentially only shows heat points above stored threshold temperatures that could develop into fire sources 15, or as a detailed representation, which reveals all details as well as the heat points. The schematic representation can also be switched to a detailed representation.The circular image 24 composed as a circular image 24 or circular ring image 25 or from successively generated circular images 24 and / or circular ring images 25 is continuously renewed from a rectangular image 26.

[0049] The circular image 24 or annular image 25 can encompass any angle and, as will be apparent to a person skilled in the art, can be any size smaller than 360°. In particular, the circular images 24 or annular images 25 can be adapted to an object to be monitored, for example, a corner area of ​​a building or storage area. Then, for example, the camera 7 can oscillate through an angle of less than 360°, and a corresponding circular image 24 or annular image 25 is assembled and displayed.

[0050] The rectangular image of camera 7, at the present aperture angle 30 of 90° x 67.5°, has an image resolution of 640 x 480 pixels and begins at the bottom with a start line 27 and ends at the top with the end line 28. The camera 7 is mounted on the mounting axis 17, which represents a rotation axis 29, in such a way that at the aperture angle 30 of 90°, it is pivoted by 45° relative to the mounting axis 17, so that the start line 27 is aligned with the mounting axis 17 or intersects it in its extension, and a start corner pixel 31 remains approximately stationary when the camera 7 rotates. An end corner pixel 32 of the end line 28 describes a circular path 33 when the camera 7 rotates.

[0051] If the 360° circular path 33 is assigned the full resolution of camera 7, the result is: 360° circumference / 67.5° aperture angle = 5.33 stitched camera images

[0052] This means: 5.33 x 480 heat pixels per 67.5° aperture angle results in a circular resolution of approximately 2,558 heat pixels for 360° resolution.

[0053] During a 360° rotation, the thermographic rectangular image 26 is created, delimited at the bottom by the start line 27 and at the top by the end line 28. This rectangular image has a height of 640 thermal pixels and a length of 2,558 thermal pixels. In the arrangement described above, the start corner pixel 31 almost always points to the same location below the mounting axis 17, which serves as the rotation axis 29. In order to be able to visually interpret this rectangular image 26, small sections of the IR thermal image are recorded along with their positions during the rotation and arranged in a row. The width of these sections varies and depends on the processing speed of the computer module 13 of the controller 10 in which these sections are joined together, and the rotation speed of the motor 20. The narrower the sections, the less distorted the overall image will be, but the more computing power the system requires.

[0054] To simulate a wide-angle lens of approximately 180° of an IR camera 6, a central section 34 of the image 26 is taken as a subsection with a width of, for example, 40 thermal pixels as precisely as possible from the center of the image, since the least image distortions are present in the center of the image, because the wider the image 26 is, the more the fisheye effect of a recording becomes apparent and the partial images can no longer be joined together without distortion.

[0055] The central section 34 is converted into a thermographic circular image 24, with the lower starting line 27 being converted into a central circular image center point 35, with the height of the central section 34 of the thermal image 26 corresponding to the radius of a circular segment image 36. Each line of the central section 34 must be converted into a circular segment line. The closer one gets to the circular image center point 35, the fewer heat pixels fit into the respective line of the circular segment image 36. Therefore, heat pixel groups must be formed that consist of several adjacent heat pixels. The closer one gets to the center, i.e., the circular image center point 35 of the circular image 24, the more heat pixels a heat pixel group contains.

[0056] Averaging the individual heat pixels of a heat pixel group results in a smoothing of the maximum temperatures. Therefore, when combining a heat pixel group into a new heat pixel, the temperature value of the hottest heat pixel in the group is always used. Using the maximum value when combining a heat pixel group is particularly advantageous when the principle described above is used for fire monitoring and displaying a fire source 15, i.e., a hotspot.

[0057] At the same time, the polar coordinates of the heat pixels are also calculated in order to be able to immediately position an extinguishing agent dispenser 8 on the fire source 15 in the event of a fire alarm. When calculating the polar coordinates, data from a position sensor located on the mounting axis 19 can be determined and processed by the controller 10. The alignment of the extinguishing agent dispenser 8 can be simplified by the laser 16 assigned to the camera 7 to take into account the trajectory path of the extinguishing agent being delivered.

[0058] To display a circular image 24 on the touchscreen 14, several circular segment images 36 are arranged one after the other and are also overwritten as the camera 7 continues to rotate.

[0059] If a camera 7 with an aperture angle 30 smaller than 90° is selected, for example, to monitor a partial area of ​​the room 1, then the start corner pixel 31 is not aligned with the fastening axis 17 and describes a circular path that is concentric with the circular path 33 of the end corner pixel 32.

[0060] Here, too, a central section 34 is extracted from image 26, which is converted into a thermographic annular image 25, so that the lower starting line 27 is converted into an inner diameter 38 and the upper end line 28 is converted into an outer diameter 39 of a circular sector image 40, whereby the height of the central section 34 of the thermal image corresponds to the difference between the outer diameter 39 and the inner diameter 38 of the circular sector image 40. The circular sector images 40 created by rotating the camera 7 are continuously combined to form the annular image 25.

[0061] Of course, circular images 24 and / or circular ring images 25 or corresponding combinations with any angle smaller than 360° can also be generated and displayed, in particular depending on the angle of rotation of the camera 7 or controlled by the image processing device 23.

[0062] To change the diameter or area to be monitored in space 1, a camera 7 with an aperture angle 30 smaller than 90° is selected and aligned such that the starting corner pixel 31 is aligned with the rotation axis 29 and the end corner pixel 32 describes a circular path that is concentric with the circular path 33 and has a diameter that is changed accordingly. As already described, a circular image 24 is generated and displayed.

[0063] If an area above the installation of the camera 7 in the room 1, for example a ceiling 5, is to be monitored, then a camera 7 with an aperture angle 30 of 90° can be selected and aligned in such a way that the starting corner pixel

[0064] 31 is not aligned with the mounting axis 17 and the end corner pixel

[0065] 32 describes a circular path that is concentric with the circular path 33 and has a different diameter. As already described, a circular ring image 25 is generated and displayed.

[0066] It will be apparent to a person skilled in the art that, by pivoting the camera 7 relative to the mounting axis 17, it is possible to successively generate, for example, a circular image 24 and several circular ring images 25, or several circular ring images 25 without a central circular image 24, with different diameters, and to align them concentrically with one another in a common representation in order to be able to capture a relatively large room 1 both centrally and in peripheral edge areas.
