A modular switch device operation and maintenance and binding verification system

By generating candidate binding sets, identifying disturbance sequences, and identifying response characteristics, the binding errors caused by the migration of sensor physical connection points in modular switchgear were resolved. This enabled accurate binding of sensors to assets and correction of safety interlock actions without interrupting power supply, thereby improving the accuracy and safety of operation and maintenance.

AI Technical Summary

Technical Problem

Existing technologies cannot effectively identify binding errors caused by the migration of sensor physical connection points in modular switchgear, and actively applying electrical side disturbances may trigger equipment protection mechanisms, making it difficult to achieve accurate binding between sensors and assets without interrupting power supply.

Method used

The candidate binding module generates a candidate binding set, the disturbance time stamp module generates an identification disturbance sequence, the response feature module collects sensor data, the binding correction module performs consistency calculations, and the chain result module generates a binding correction table, thereby realizing online self-calibration and accurate verification of sensors and assets.

Benefits of technology

Identifying binding errors caused by the migration of sensor physical connection points without interrupting power supply reduces the risk of safety interlock actions pointing to the wrong object, ensures that maintenance data corresponds to the actual physical object, and improves the accuracy and safety of modular switchgear maintenance.
