Steel plate oddment monitoring method and system

The invention discloses a steel plate oddment monitoring method which is applied in a steel plate oddment monitoring system. The method includes that a server receives layout results from a layout system and determines whether the layout results contain oddment information; if so, a cutting site management terminal acquires the layout results from the server according to production plan, an operator prepares material according to plate blank information, a numerical-control cutting platform cuts the prepared plate blanks according to a numerical-control program and layout images, the cutting site management terminal sends oddment information to a RFID reader after cutting of the numerical-control cutting platform is completed, the RFID reader writes the oddment information into a RFID and embeds the RFID into the oddment, and the operator stores the oddment with the embedded RFID into a plate blank bin and sends storing position of the oddment to the server through a management terminal of the plate blank bin. By the aid of the method, steel plate oddment monitoring and management can be realized effectively, relevant enterprises can utilize raw material effectively, material utilization can be improved, and production cost can be reduced.
