At the heart of every reliable elevator system lies a core necessity: precise positioning. SURAPID Elevator, a key brand under the New Xi’ao Elevator Group, leverages the Group’s advanced R&D ecosystem to solve persistent operational challenges. Central to our safety portfolio is the Absolute Positioning System (APS)—a technology developed by New Xi’ao Group that moves beyond traditional sensing to provide a high-tech "digital eye" for the elevator.
Traditional elevators rely on optical switches or pulse encoders, which often lead to two major industry pain points:
-Leveling Drift: Over time, mechanical wear leads to cumulative errors. This causes a "step" at the floor landing—a trip hazard that can trap suitcase wheels or cause passengers to fall.
-Power-Loss Amnesia: Traditional systems "lose their way" during power outages. Upon restart, the elevator must perform a slow "reset run" to the base station to find its position, causing frustrating downtime.
To eliminate these issues, SURAPID integrates New Xi’ao’s APS technology, which utilizes a sophisticated "Magnetic Tape + Dual Sensor" architecture:
Real-Time Data Reading: The car is equipped with dual-path redundant sensors that constantly "read" encoded position data from a high-precision magnetic tape running the full height of the hoistway.
Absolute Coordinate Tracking: Because the position data is physically encoded on the tape, the system provides absolute coordinates at every millisecond. The elevator car never "forgets" its location, even during a total power failure, eliminating the need for recalibration runs.
Predictive Safety with 200Hz Processing: The system’s control core boasts a sampling rate of 200 cycles per second. This powerful real-time calculation allows the system to predict potential hazards—such as overspeed or abnormal shaft vibrations—before they occur. By identifying these anomalies in milliseconds, the APS can trigger safety protocols and bring the car to a secure state before any danger reaches the passengers.
This high-frequency monitoring results in a superior ride experience. With millimeter-level leveling accuracy (< 1mm), SURAPID elevators provide a perfectly flush landing at every floor. This precision optimizes the acceleration and deceleration curves, ensuring a smooth, "jerk-free" transition that passengers can feel.
For regional partners and contractors, New Xi’ao’s technical innovation simplifies onsite operations:
One-Person Installation: The APS device is compact and designed for rapid installation from the car top, significantly reducing labor hours compared to traditional multi-sensor setups.
Environmental Resilience: Every unit is dustproof and waterproof, ensuring that the high-precision reading remains accurate even in harsh construction environments or humid climates.
Group Backing: This technology is produced in New Xi’ao’s automated electronic workshops, where proprietary auto-magnetizing machines ensure the magnetic tape's signal longevity for the entire lifespan of the elevator.
By combining New Xi’ao Group’s technical depth with SURAPID’s agile market implementation, we provide our partners with a solution that doesn't just meet safety standards—it redefines them through hard data and engineering excellence.
