Abstract

The invention discloses a light curtain sensor. The light curtain sensor comprises a transmitting circuit, a receiving circuit, a transmitting control module and a receiving control module; the transmitting circuit comprises a plurality of infrared transmitting tubes; the transmitting circuit is connected with the transmitting control module; the transmitting control module is used for controllingthe plurality of infrared transmitting tubes to sequentially transmit infrared light according to a preset sequence; the receiving circuit comprises a plurality of infrared receiving tubes; the number of the infrared receiving tubes is the same as the number of the infrared transmitting tubes; each infrared transmitting tube is corresponding to one unique infrared receiving tube; the infrared transmitting tubes and the infrared receiving tubes, which are corresponding to each other, are arranged on the same straight line; the receiving circuit is connected with the receiving control module; and the receiving control module is used for controlling the plurality of infrared receiving tubes to sequentially receive infrared light according to a preset sequence.

Description

technical field [0001] The present application relates to the technical field of light curtain sensors, in particular to a light curtain sensor. Background technique [0002] Traditional light curtain sensors generally work in a line-synchronous manner, and the sending and receiving parties generate synchronous timing pulses from electronic circuits, and there must be wire connections between the light emitter and the light receiver to realize signal transmission. However, in the occasions where the sending and receiving distance is long or the field wiring is difficult, the application of this type of light curtain sensor is greatly limited. Contents of the invention [0003] In view of this, the application provides a light curtain sensor, which does not need to connect the wires used in the transmitting circuit and the receiving circuit, and uses independent control modules for control, so as to realize the optical synchronization of the transmitting circuit and the rec...
