The invention provides a correlation light curtain, a detection system and an installation detection method of the correlation light curtain. An emitter of the correlation light curtain controls a light emitting tube to emit a detection light beam through a control circuit; the receiver receives the detection light beam through the receiving tube; the correlation light curtain controls the light-emitting tube to emit detection light beams with different intensities through the control circuit in different scanning periods of the detection working mode; or the amplification circuit is controlled to use different amplification factors, and the indication unit is controlled to display the scanning period times of the detection light beam received by the receiving tube in a preset period. According to the invention, the indication unit is used for displaying the scanning period times of the detection light beam emitted by the emitter and successfully received by the receiving tube in a preset period; therefore, the installation position and angle of the receiver are adjusted according to the number of times so that the numerical value of the number of times can reach the maximum state,alignment of the light-emitting tube and the receiving tube is achieved, deviation caused by welding, assembling, installation and other reasons is eliminated, and the working state of the opposite-emitting light curtain is improved.
Description
technical field [0001] The invention relates to the field of industrial detection, in particular to a through-beam light curtain, a detection system and an installation and detection method for the through-beam light curtain. Background technique [0002] The through-beam light curtain is a detection device used to check whether an object has entered a specific area. It is widely used in various mechanical equipment in the field of industrial production. Its uses include detecting whether a human body has entered or a limb has extended into a dangerous area, detecting whether a workpiece on a conveyor has reached a predetermined position, and measuring the external dimensions of an object, etc. The through-beam light curtain is generally composed of a transmitter and a receiver, which are installed oppositely at both ends of the area to be detected. In the light curtain, the transmitter is equipped with multiple luminous tubes, which can emit multiple beams, and the receive...
