When the face recognition device (gate device) is successfully connected with the network, the face recognition device prompts that the tool connection is normal to indicate that the wired network connection is normal.

The present device number refers to the ID of the face recognition device itself, i.e., the device ID of the gate device. And scanning a code input device ID number on a test tool of the test terminal, namely scanning the code to input the device number. And when the equipment number is consistent with the equipment number stored in the test terminal, the test terminal generates an activation instruction and sends the activation instruction to the face recognition equipment so as to activate a test program of the face recognition equipment.

The test terminal can perform verification and identification on the device number obtained by code scanning, and if the device number is correct, step S202 is executed.

And if the number of the device is wrong or the test terminal cannot read the number of the device, the test program of the face recognition device cannot be activated.

When the number of the device is wrong, the tester needs to replace the tested face recognition device until the number of the replaced face recognition device is the same as the number of the device stored in the test terminal.
