Heat treatment plate size mistake proofing and reverse checking method and heat treatment plate size mistake proofing and reverse checking system

The invention discloses a heat treatment plate size error-proofing and reverse-checking method and system, and relates to the technical field of heat treatment, and the method comprises the following steps: measuring the size of a steel plate in a current heat treatment process to obtain first size data; obtaining size data of the steel plate in the current heat treatment process in the manufacturing execution system to obtain second size data; comparing the first size data with the second size data, and generating different alarm signals according to a difference value between the first size data and the second size data; and displaying the alarm signal in a secondary control system. According to the invention, an error-proofing and anti-checking interface is added to the secondary control system, the measured actual data is compared with the data from the MES, the size out-of-tolerance value is set to a corresponding range by designing a reasonable query and comparison interface, and different colors are di
