And step nine, the PLC control module 1 receives the position and the state information of the current execution action of the key robot 6 and sends the position and the state information of the current execution action to the upper computer 2 through the switch 5.

Step ten, the upper computer 2 receives the position and state information of the current execution action of the PLC control module 1, and synchronously receives the key detection result information fed back by the DUT module 4 through the switch 5 and the router 10 (i.e., when the DUT module 4 is operated by the key robot 6 to execute a key operation, the key detection result information output correspondingly, such as whether the key can be normally pressed and popped up, whether the key position lacks a key, etc., on the basis of the key trigger signal received in the seventh step, the position and state information of the current execution action is correspondingly matched with the key detection result information to determine whether each key is qualified, etc., and simultaneously displayed to the human-computer interaction device 13.

Step eleven, in the process that the key robot 6 executes key operation on the DUT module 4, the upper computer 2 collects images of the DUT module 4 in real time through controlling the image collection module 9; after the key detection of the key robot 6 is completed, a key detection completion signal is sent to the PLC control module 1 through the switch 5; after receiving the key detection completion signal, the PLC control module 1 sends an image processing signal to the image acquisition module 9 through the upper computer 2, and the image acquisition module 9 completes image processing (such as brightness detection, dimension detection, color detection and other processing) on the DUT module 4 according to the image processing signal, that is, whether each key is bright or not, whether the key brightness color is abnormal or not is determined according to the image processing result, so as to obtain corresponding determination result information), sends the determination result information to the upper computer 2, and sends the determination result information to the PLC control module 1 through the upper computer 2.

Step twelve, the PLC control module 1 receives the determination result information, and completes data processing of the determination result information (i.e., makes the new DUT product information correspond to the determination result information to obtain a corresponding determination data processing result) according to the new DUT product information received in the step five, and sends the determination data processing result to the upper computer 2 through the switch 5. Meanwhile, the PLC control module 1 disconnects the control of the limiting device 12, and controls the air cylinder 15 to release the connection line (i.e., the power supply interface and the ground interface) between the safety test unit 7 and the DUT module 4 and the connection line (i.e., the network communication interface) between the router 10 and the DUT module 4.
