LIGHT GRID AND METHOD OF MONITORING A MONITORED ZONE
Abstract:
A light grid (10) is provided having a plurality of light transmitters (14) for transmitting a respective monitoring light beam (38) and having a plurality of associated light receivers (22) to generate an objection detection signal (42a-d) depending on the reception of the monitoring light beam, having a control (30, 32) which is configured to divide the monitoring light beams (30) into groups and to consecutively activate the monitoring light beams (38) of the groups, wherein, in a group-wise parallel monitoring sequence, a respective monitoring light bream (34) of each group is activated in parallel, as well as having a first bus (34) over which the object detection signals can be output to the control (32) by the light receivers (26, 26). The light receivers (22, 26) are in this respect configured to output the object detection signals to the control (32) in a time multiplex process.
Abstract(Chinese):

提供了一种光栅（10），其具有多个发射器（14），用于传输相应的监视光束（38）并具有多个相关联的光接收器（22），以产生依赖于该物体的反射检测信号（42a-d） 在监视光束的接收时，具有被配置为将监视光束（30）分成组并且连续地激活组的监视光束（38）的控制（30,32），其中，在 分组并行监视序列，每组的相应监视光斩波（34）被并行激活，以及具有第一总线（34），物体检测信号可以通过该第一总线输出到控制器（32） 光接收器（26,26）。 在这方面，光接收器（22,26）配置成在时间复用处理中将对象检测信号输出到控制器（32）。
