A Method for Recording Operation History Based on Human-Machine Interface

Abstract

The invention discloses a method for recording operation history based on a man-machine interface, comprising a data acquisition gateway, an operation history data analysis module, an HMI system, and a data storage module, including the following steps: deploying the data acquisition gateway on a man-machine interface computer Or on the CS server of the HMI system; the communication message of the CS server is generated through the HMI system; the operation history data analysis and recording module filters out all the communication messages of the CS server through the original socket; the communication message of the CS server is repackaged , forwarded to the operation history data analysis module; the operation history data analysis module decomposes according to the message type, analyzes the data in it, and saves it into the relational database of the data storage module; the data storage module stores the corresponding screen information and screen operation . The present invention collects data by using the hybrid mode of the network card, without installing third-party software.

Description

technical field [0001] The invention relates to the field of automation, in particular to a man-machine interface-based operation history recording method for recording terminal users. Background technique [0002] In the field of automation systems, it is a relatively common means to use operation history records to manage the production management process and process traceability. However, quantitative analysis is usually carried out on the control system, and the commonly used method is to use IBA for analysis. However, there are relatively few operation records for the man-machine interface, and the operation record of the man-machine interface for ABB's 800XA system is still blank. [0003] The use of IBA software to record operation history has the following limitations: the IBA system is connected to the control network to directly collect data, the collected data is the data that has been written to the PLC, which operating terminal the data comes from, and the middl...

However, quantitative analysis is usually carried out on the control system, and the commonly used method is to use IBA for analysis. However, there are relatively few operation records for the man-machine interface. For ABB's 800XA system, the man-machine interface operation record is still blank

[0003] The use of IBA software to record operation history has the following limitations: the IBA system is connected to the control network to directly collect data, the collected data is the data that has been written to the PLC, which operating terminal the data comes from, and the middle of the data processing process cannot be located

The author implements a callback client according to the corresponding OPC standard in ABB's 800XA system documentation, and adjusts the OPC server collection cycle in the 800XA system to the minimum, and cannot capture all operations
