Abstract

The invention provides a method for guaranteeing data integrity of an outlet steel coil on a steel coil production line. Three main signals determining data integrity of the steel coil of the outlet segment are a tail cutting completion signal, a reeling completion signal and a coil unloading completion signal; when a signal (real or simulated) is received, if works that should be finished by previous one signal or previous two signal are not done, the signal is considered as not received, and simulation should be successively performed from the most previous signal that is not received. The method of the invention guarantees the integrity of the data on the condition that an outlet signal is abnormal.

Description

technical field [0001] The invention relates to a method in a process control system of a steel coil production line, in particular to a process-level guarantee method for the integrity of export steel coil production data in the process control system of a steel coil production line. In particular, it relates to a method for ensuring the integrity of steel coil production data at the process level under the abnormal condition of a key signal for establishing a steel coil production data record at an exit section. Background technique [0002] In the process control system of the steel coil production line, ensuring the integrity of the steel coil production data is a main task of the process control system. [0003] Usually a coil production line consists of an entrance section, an intermediate section and an exit section. The production data of a steel coil is established and completed by the process control system according to the control signals and detection data sent ...
