The PIN code calculation function module is integrated in an MES system of a host factory. The PIN code calculation function module obtains the VIN code of the automobile by calling the input parameters (obtained by calling data in an MES system or obtained by scanning a code gun through electrical detection equipment or called through DLL of the MES system), verifies the check digit of the VIN code, and generates the PIN code with the length of 8 bits according to the VIN code after the verification is passed.
And the PIN code calculation function module in the MES system of the host factory is connected to the electric detection equipment through a web interface service and used for sending the generated PIN code serving as an information node to the electric detection equipment.
