if the current image data does not comprise the identifiable material bar code, the next action is not performed;
the equipment automation system completes the verification of the material information by the following modes:
the equipment automation system acquires the identity of the material verification equipment carried by the material information after receiving the material information sent by the material verification equipment;
determining standard material information corresponding to the identity marks according to the mapping relation between the prestored plurality of standard material information and the identity marks of the plurality of material verification devices;
comparing the received material information with the standard material information;
if the received material information is consistent with the standard material information, the materials used by the corresponding production equipment are correct.
9. The material verification control system of claim 8, wherein the material verification device comprises a material detection sensor and a master control chip, the material detection sensor being connected to the master control chip;
the material checking device is also used for detecting whether a material bar code exists in the scanning area, and generating a trigger signal and sending the trigger signal to the main control chip if the material bar code exists in the scanning area;
and the main control chip receives the trigger signal to generate a trigger scanning event in the first communication format.
10. The material verification control system of claim 9, wherein the equipment automation system is further connected to a display terminal;
the device automation system is further configured to:
comparing the received material information with preset standard material information, and if the received material information is consistent with the standard material information, generating a production equipment starting instruction and sending the production equipment starting instruction to the production equipment;
if the received material information is inconsistent with the standard material information, generating alarm prompt information, and sending the alarm prompt information to the display terminal for display.
