SET history control system

摘要

A SET history control system is supervised by a system control computer. A bar code printer issues product identification information and a SET number in bar code form, according to information received from the system control computer, which are then attached to a product in a production line. A number of failure code books contain various failure codes in bar code form, each failure code corresponding to a particular type of failure which can occur in the production process. Bar code scanners are used to scan the product identification information and SET number from the bar code attached to a product and a failure code from a failure code book when a failure occurs and pass the scanned information to the system control computer. The system control computer analyzes the scanned information and stores history information by SET in a memory device concerning the assembly, checking and despatching processes of each SET.
