Definitions

  • the invention relates to a sensor arrangement for a construction machine according to the preamble of claim 1.
  • Such sensor arrangements for construction machines are known from practice.
  • the measured data obtained by them are used to check the work result of the construction machine, in particular the quality of this work result, and to adjust the operating parameters of the construction machine according to the measured data in order to achieve the best possible work result.
  • a disadvantage of the conventional sensor arrangements is that they are exposed by the working environment of the construction machine of a very high load and pollution.
  • the unreliable, erroneous measurement data can hinder the operation of the construction machine and possibly even further degrade the achieved work result if the operating parameters of the construction machine are incorrectly adjusted due to the unreliable measurement data.
  • Object of the present invention is to provide a sensor arrangement available that enables a more reliable operation of the construction machine with structurally simple means possible.
  • the sensor arrangement according to the invention is characterized in that a lighting device for illuminating the scanning region or the scanning point of the sensor is integrated into the sensor arrangement.
  • a lighting device for illuminating the scanning region or the scanning point of the sensor is integrated into the sensor arrangement.
  • cabling to an external lighting device can be avoided by integrating the lighting device into the sensor arrangement, and that the quality of the lighting is independent of whether and, if appropriate, in what form external lighting fixtures are present on the construction site (for example on masts ). Furthermore, it is no longer necessary to direct an existing work light of the construction machine to the scanning field in order to check the quality of this scanning field, so that the work light can now be used as intended for illuminating the working area of the construction machine.
  • the sensor present in the sensor arrangement can be, for example, a mechanical sensor or a contactless sensor. It is also conceivable that a plurality of sensors are present in the sensor arrangement, and that these sensors evaluate a common scanning field or different scanning fields.
  • the senor may be an optical sensor, an inductive sensor, a capacitive sensor or an ultrasonic sensor.
  • the illumination device provided according to the invention is advantageous in order to be able to visually check, for example, the surface quality and the degree of soiling of the scanning field. It is conceivable, however, that a light or shade pattern obtained by means of the illumination device is detected in the scanning field by means of the sensor and used to obtain measured data.
  • the lighting device could generate a structured light pattern, for example a line or a grid. Depending on the position and / or deformation of this light pattern, it would be possible to deduce the properties of the scanning field and thus the quality of the work result of the construction machine.
  • the lighting device could be designed to emit visible and / or infrared light. Visible light has the advantage that it facilitates a visual inspection of the scanning field by the operator of the construction machine.
  • the lighting device may have optics for fixing and optionally for changing the area illuminated by the lighting device.
  • This lighting device may contain reflectors and / or optical lenses and thus define where the illuminated area lies and which dimensions it has.
  • the optics are adjustable in order to change the position and / or the size of the area illuminated by the illumination device.
  • the illuminated area can be adapted to changing working conditions, for example to a changing distance between the sensor and the scanning field.
  • the brightness of the illumination device is variable in order to enable optimum illumination of the working field while at the same time minimizing energy consumption.
  • the senor does not continuously acquire measurement data, but that it is set up for the discontinuous acquisition of measurement data, for example, after fixed or variable measurement intervals.
  • the lighting device is set up so that it only emits light during the acquisition of measured data by the sensor, so that energy can be saved during the inactive state of the sensor.
  • the sensor arrangement has a camera aligned with the scanning field. By means of this camera, the operator can visually check the scanning field illuminated by the illumination device without having to go to the scanning field itself.
  • the lighting device can be activated independently of the operation of the sensor.
  • the lighting device can be turned on, for example, to visually inspect the scanning field without the sensor also having to be switched on.
  • the invention also relates to a construction machine, for example a paver or a feeder, with a sensor arrangement of the type described above.
  • FIG. 1 shows a perspective view of an embodiment of a construction machine 1 with a sensor assembly according to the invention 2.
  • the construction machine 1 may be a paver or a feeder for a paver. However, it may also be another construction machine that can be used in darkness or in dark rooms, for example in a tunnel, or has darkened areas in its interior, but from which measurement data is to be obtained.
  • the sensor assembly 2 is attached by means of a boom 3 to a component 4 of the construction machine 1, for example on an outer or inner wall 4 of the construction machine 1.
  • a boom 3 to a component 4 of the construction machine 1, for example on an outer or inner wall 4 of the construction machine 1.
  • the sensor assembly 2 in the component 4 of the construction machine. 1 is integrated.
  • the sensor arrangement 2 has a sensor 5 which is set up to obtain measured data from a scanning region 6.
  • Dashed lines 7 indicate the scanning or detection angle of the sensor 5.
  • the sensor 5 may be a mechanical or non-contact sensor.
  • it is an ultrasonic material sensor on a conveyor screw of the construction machine 1, an ultrasonic level sensor or a mechanical long-range sensor.
  • the measurement data determined by the sensor 5 serve to represent a condition on or in the construction machine 1 or a work result achieved by means of the construction machine 1.
  • a lighting device 8 is integrated in the sensor arrangement 2.
  • the lighting device 8 comprises a light source 9 for generating, for example, visible light.
  • the light source 9 may be an LED or a field of LEDs.
  • the lighting device 8 has a front of the light source.
  • This optics 10 may include reflectors and / or lenses. It serves to bundle the light generated by the light source 9 to a beam cone 11.
  • an illuminated region 13 is formed by the illumination.
  • the optics of the illumination device 8 are adjusted so that the illuminated region 13 coincides exactly with the scanning region 6 of the sensor 5 matches.
  • the light source 9 and the optics 10 are preferably controllable by means of a controller so that the brightness of the beam cone 11 and the divergence of the beam cone 11 are variable, so that the lighting, for example, adapt to a changing distance between the sensor assembly 2 and the work surface 12 can.
  • the lighting device 8 can illuminate the area 13 on the work surface 12 when the sensor 5 is active and detects measurement data, or when the lighting device 8 was activated independently of the operation of the sensor 5 by an operator of the construction machine 1.
  • the sensor assembly 2 can be changed in many ways. For example, it would be possible to integrate a plurality of sensors 5 in the sensor device 2.
  • a camera could be provided in the sensor arrangement 2 by means of which the area 13 illuminated by the lighting device 8 is detected. The image supplied by the camera could be displayed on a display device for the operator of the construction machine 1.
