- the axis of rotation 10 is an angle encoder 28 is associated with the control device 23 is connected. It is preferably an absolute angle encoder with digital output and one Minimum resolution of 12 bits or more.
- the control device is via a serial interface 29 connected to a computer 31.
- the computer 31 are a screen 32, an operating keyboard 33 and a log printer 34 is assigned.
- the drive motor 22 is from the computer 31 via the Control device 23 driven.
- the rotational position of the The axis of rotation 10 is scanned by the angle encoder and its Signals, for example a 12 bit parallel bus, fed to the control device 23.
- the two infrared cameras 11, 12 are one Feed line 35a fed from the control device 23.
- the video signals from the infrared camera 11, 12 are fed to the computer via a video line 35b. Here they are digitized and the data is saved on Screen 27 shown or from the log printer 28 printed out.
- Warning device 36 activated.
- the latter can, for example loading from the garbage bunker 1 in the driver's cab Cranes 43, 43 'may be arranged.
- control device 23 connected control element 37 can the warning is acknowledged by the crane operator.
- the duration of the Scanning a bunker is determined by the circumstances of the individual case.
- the gripper of the two cranes 43 arranged in the waste bunker, 43 ' is a longitudinal 44, 45, transverse 46, 47 and depth sensor 48, 49 assigned. These represent the position of the grippers fixed and transmit the data to the control device 23.
- controllable heatable test element 51 arranged with the periodic functionality of the System is checked by heating the test element 51 a test alarm is triggered. These test alarms are also registered and printed out in the log.
- control device has 23 an output 52 for a further alarm message and an output 53 for a system failure message.
- the extinguishing and cooling-off can automatically with a locally targeted extinguishing agent like sprinkling or one of the crane grabs is moved into position manually or blind, which then Extinguishing media positioned in the hot place or that hot material.
- the infrared camera 11 in Fig. 3 has a double-walled Camera housing 61, in which the actual thermal imaging camera 62 is arranged.
- the thermal imager 62 preferably has a sensitivity range of 8 ⁇ m to 12 ⁇ m and preferably shows temperature differences from approx. 2 ° C or more.
- the bottom 63 of the Infrared camera 11 is partially IR-transparent Glass window 64 formed, e.g. made of germanium glass.
- In the upper part of the camera housing 61 there is an inlet 65 for flushing air and at the bottom 63 there are outlet openings 66 arranged for the purge air.
- the thermal imager 62 has connections 68, 69 for both the supply and also for the transmission of thermal images.
- Farther is located in the upper part of the camera housing 61 Water inlet 71 for cooling water. The water cooling will - only when a predetermined temperature is reached in the Range from, for example, 50 to 90 ° C - by a Temperature sensors arranged on the outside of the camera housing 61 72 activated by a capillary tube 73 Valve 74 in one on the lower part of the camera body 61 arranged water outlet 75 operated.
- the Water cooling of the infrared camera is on one under Pressurized water pipe, for example to the City management or that of the sprinkler system, connected.
- a simple one Thermal imaging camera without self-cooling which is not an actual one Thermal image, but only provides heat points become.
- FIG. 4 is an event image 81 on the computer 31 assigned screen 32 shown.
- the upper part of the event image shows two camera images 82, 83 a place of increased temperature, a source of fire in the Garbage bunker, as bright spot 84, 84 'appears.
- middle picture 85 is the position 86, 87 of the Grapple of the two cranes and the fire source 84 in Floor plan and in a third lower picture 88 in Side view shown.
- X, Y, Z are the coordinates of the source of the fire specified.
- the screen display makes the work of the Operating personnel and accelerates any Intervention.
