摘要： A distance measuring optoelectronic sensor for detecting a target object in a monitored zone is provided that has a light transmitter for transmitting light pulses, a deflection unit for a periodic scanning of the monitored zone by the light pulses, a light receiver for generating a received signal from the light pulses reflected or remitted by objects in the monitored zone, and a control and evaluation unit that is configured to determine the distance of an object from a time of flight of a light pulse and to transmit light pulses of different intensity, For the detection of a target object having a specific reflection capability, the control and evaluation unit is here furthermore configured to transmit light pulses adapted to the reflection capability and to a range and to vary the light pulses in accordance with different ranges for the distinction between the target object and another object.

摘要： A safe optoelectronic sensor is provided for securing a monitored zone comprising at least one machine, wherein the sensor has at least one light receiver for generating a received signal from received light from the monitored zone and a control and evaluation unit that is configured to determine distances from objects in the monitored zone from the received signal, and to treat gaps, i.e. safety relevant part regions of the monitored zone in which no reliable distance can be determined, as an object at a predefined distance. The predefined distance here corresponds to a height for securing against reach over.

摘要： An optoelectronic sensor (10) for safe detection of objects (32, 34) of a minimum size in a monitoring area (12), the sensor (10) having an image sensor (16a-b) for acquiring image data of the monitoring area (12) and an evaluation unit (24) configured to detect, in the image data, both finely detected objects (34, 36) with a fine detection capability and coarsely detected objects (32) with a coarse detection capability, the coarse detection capability being coarser than the fine detection capability, and to ignore finely detected objects (36) which are not in a vicinity (38) of a coarsely detected object (32).

摘要： An optoelectronic sensor for detecting objects in a monitored zone is provided having at least one light receiver for generating measurement data from received light from the monitored zone and having a safe evaluation unit that has at least two processing channels for a redundant processing of the measurement data and having a comparison unit for comparing processing results of the processing channels to uncover errors in a processing channel 30a-b. The processing channels are here each configured for a determination of a signature with respect to their processing results; and the comparator unit is configured for a comparison of the signatures.

摘要： A method of configuring at least one hazard zone to be monitored by at least one three-dimensional (3D) sensor includes fixing outer surfaces, where the at least one hazard zone is a volume defined by the outer surfaces, and is a zone in which a machine to be secured is located. Additionally, a check is made during the configuration or after the configuration whether the outer surfaces are visible to the at least one 3D sensor.

摘要： A method of securing at least one hazard zone comprising a hazardous machine is provided, wherein objects are detected in an environment of the hazard zone from measured data of at least one 3D sensor, and wherein a safety directed reaction of the machine takes place on an impending danger. A switch is made to at least one new hazard zone to be activated during the operation of the machine and a check is made whether the new hazard zone to be secured is free of objects.
