[0076] As a second example of security-related information that can be displayed in the display unit, Image 6 Shows a pictogram representing the entry of an object into the protected field.

[0077] Objects entering the protected field or the warning zone can also be displayed with symbols such as hands; the hand can appear in the form of a flashing light according to the position of the object in the protected field or the warning zone for a long time. The position or movement direction of the object can also be represented by the specific orientation or movement direction of the hand shown in the display field.

[0078] Figure 7 A first embodiment of a location-dependent display of an object entering a protected field or warning zone is shown. The extension of the protected field S and the warning zone W in the radial direction is displayed by the highlight field. In addition, the current object position P of the object in the warning zone in this case is displayed. The displ...

Abstract

The invention relates to a sensor for detecting objects in a monitoring area. The sensor has a display unit that is comprised of a series of lamps (13) with a linear arrangement of lamps. The series of lamps is arranged around an axis (D) of rotation running parallel to its longitudinal axis and rotates at a specific rotary speed. The series of lamps (13) is controlled via a control unit in such a way that the columns of a matrix-type display field (18) to be presented at a clock rate of the display field are individually output one after the other to the series of lamps (13) and displayed with it. The clock rate is adapted to the rotary speed in such a way that these displays complement one another to form a standing image of the display field (18). The sensor is a safety sensor.

Description

Technical field [0001] The invention relates to a sensor for detecting objects in a monitoring area. Background technique [0002] This type of sensor can be designed in the form of an optical sensor, in particular, it is usually used to detect objects. [0003] This sensor has a suitable display unit to display status messages, alarm messages, etc. In the simplest case, such a display unit consists of a single LED, which, for example, emits a flashing light or a constant light signal when delivering an alarm message. [0004] As the functional range of the sensor increases to the point where the sensor must be used to output complex text messages or even graphic effects, the requirements for the display unit are also rising. The use of single or multiple digital seven-segment displays to output text messages in the form of alphanumeric characters is well known. However, the integration of this type of seven-segment display leads to an undesirably high degree of engineering work a...
