Problems solved by technology
In the actual production process, often due to problems such as photoelectric sensor pollution and failure, the position judgment of the plate and the control of the roller table operation are affected, resulting in shutdown due to failures such as blockage, collision, and counting errors, which affect production
[0003] E.g figure 2 As shown, when the stop sensor of this roller table fails, it will happen that the current roller table can run normally when the current roller table is running; however, the current roller table stops running for some reason, because the stop sensor on the failure without sending a signal, the roller table continues to run, resulting in a collision plate failure

Embodiment Construction
[0016] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0017] Such as figure 1 As shown, the present invention provides a method for automatic identification of photoelectric sensor faults in a wood-based panel production line, comprising the following steps:
[0018] (1) According to the production situation at the production site, statistically analyze the action of each photoelectric sensor on the production line, and use two photoelectric sensors with the same number of actions and similar action time as the relevant sensors. Generally speaking, they are located on the same conveyor table All the photoelectric sensors on the top can be used as related sensors, as in this embodiment, the first and second photoelectric sensors are used as related sensors;
[0019] (2) Collect the action state of each photoelectric sensor in the relevant sensors, and perform defibrillation processing on the ...

The invention discloses a method for automatically identifying faults of photoelectric sensors on an artificial board production line. The method comprises the following steps of: (1) confirming related sensors according to action times and action time of the photoelectric sensors; and (2) collecting action states of the related sensors, judging whether all the photoelectric sensor act in a unified way, and giving out an alarm when actions are inconsistent. The method can automatically identify the faults of the photoelectric sensors on the artificial board production line, reduces the phenomena such as parking caused by the sensor faults, and ensures the normal operation of the production.
Description
technical field [0001] The invention belongs to the field of fault identification, in particular to a method for identifying when a photoelectric sensor on a wood-based panel production line fails. Background technique [0002] In the production process of wood-based panels, photoelectric sensors are generally used to analyze and control the position and transfer of the panels. In the actual production process, often due to problems such as photoelectric sensor pollution and failure, the position judgment of the plate and the operation control of the roller table are affected, resulting in shutdown due to failures such as blockage, collision, and counting errors, affecting production. [0003] For example figure 2 As shown, when the stop sensor of this roller table fails, it will happen that the current roller table can run normally when the current roller table is running; however, the current roller table stops running for some reason, because the stop sensor on this roll...
