An audit tracking method and system for an MES system

Abstract

The invention discloses an audit tracking method and system for an MES system, and the method comprises the steps: monitoring all user operations on the MES system, and obtaining the data content associated with the user operations in real time; generating audit log information from the associated data content according to the user operation, wherein the audit log information comprises the data content, the operation occurrence time and a corresponding user ID for executing the operation; Storing the audit log information into a database; receiving a log auditing instruction input by a manager, and extracting a keyword of the log auditing instruction according to a preset rule; Reading the database and screening audit log information containing the keywords in the database; and outputtingthe screened audit log information. According to the invention, the functions of recording and analyzing the user operation of the MES system and facilitating the manager to look up the audit log information are realized, and the supervision strength and the post-event tracing strength on the user operation are effectively improved.

Description

technical field [0001] The invention relates to the field of enterprise affairs management, in particular to an audit trail method and system of an MES system. Background technique [0002] The production process workflow technology of the process enterprise needs to solve the production coordination problem of multiple links in the complex process production process. MES (Manufacturing Execution System, Manufacturing Execution System) is a workshop-oriented information execution system located between the planning management system at the upper level of the production enterprise and the industrial control system at the field level. It controls the entire production process from production order placement to product completion. Carry out production information management and data processing, including order data release, production instruction data release, production process execution monitoring, on-site production data collection, data statistical processing and reporting,...

AI Technical Summary

Problems solved by technology

[0003] The current MES system is not equipped with a complete audit trail system, causing some criminals to falsify during the production process, and even maliciously tamper with the data in the system. Since the system does not record these events, it cannot reconstruct and analyze the events in time. However, it is impossible to determine the time, cause and process of the incident, so it is difficult to trace the course of the incident and it cannot play a deterrent role without monitoring the user, and the pre-prevention and post-event tracing of system security incidents are weak.
