AI Technical Summary
Existing displacement monitoring methods have problems such as complex wiring, high cost, inconvenient maintenance and high environmental dependence in power transmission line equipment, substation structure, track facilities and large electromechanical equipment. They are difficult to detect minute displacements or loosening of key components in a timely manner, leading to mechanical failures and safety hazards.
The displacement monitoring device, based on UHF RFID technology, controls the coupling state between the RFID chip and the antenna through a mechanical pin switch. The RFID tag is actively activated when displacement occurs, enabling automatic sensing and long-distance identification. It is then combined with a data processing terminal for centralized management.
It enables automatic detection of displacement events and multi-level alarms, reduces wiring and maintenance costs, is suitable for large-scale deployment in environments where wiring is difficult, and improves the engineering practicality and long-term operational reliability of the system.
