Abstract
To address the secondary entrapment risk and the single-point protection defect of elevator power-off emergency devices, a multi-level safety protection system was designed based on a Programmable Logic Controller (PLC) and permanent magnet synchronous door machine star-sealing technology. The system is centered on the S7-200smart PLC and integrates the Auto Rescue Device (ARD) for elevator emergency leveling during power outages, establishing an active rescue-passive protection-fail-safe framework. Experimental verification shows that the system can achieve 100% emergency leveling rescue, with a braking torque of 15.2 Nꞏm, far exceeding the door-closing torque of 4.5 Nꞏm, completely eliminating secondary entrapment. The system operates reliably, providing an innovative solution for elevator safety.
Railway level crossings remain a persistent source of accidents and fatalities on mixed road-rail networks, particularly where crossings are unmanned or rely on manual gate operation. This paper presents the design, structural validation, and prototype implementation of an automated railway barricade in which a Program...

The modernization of power systems necessitates rigorous full-circuit testing prior to equipment commissioning. At 220 kV substations, these testing procedures are frequently hindered by the construction progress of primary equipment and stringent power outage schedules. This paper proposes a design solution for a full...
