AI Technical Summary
Existing cable tray tilt monitoring technology relies on a single preset threshold, which cannot accurately assess the tilt status of the internal cable group, easily leading to false alarms or missed alarms, and making it difficult to objectively assess the risk of damage to the system.
The tilt angle and strain are obtained synchronously using a high-frequency gyroscope and fiber optic strain gauge. Combined with the off-center shear force and vertical support reaction force, the cumulative dissipated energy is calculated by inversely deriving the cable's slip displacement and frictional dissipation power. The critical characteristic value of instability is extracted, and an interlocking command without preset parameters is generated to cut off the current and activate the electromagnetic locking mechanism.
It enables accurate real-time monitoring of the tilt status of cable trays, distinguishes between environmental disturbances and irreversible lateral slippage, avoids false alarms and missed alarms, and improves the safety and reliability of electrical laying systems.
