UCMP Elevator Safety Testing with DE-928U System
With the rise of urbanization and the construction of more high-rise buildings, elevators have become a critical part of daily life. In China, rapid economic development has accelerated this trend, making elevators a common feature in both residential and commercial properties. However, this increased reliance on vertical transportation has brought elevator safety into sharp focus, especially as accidents and malfunctions continue to be reported in recent years.
One of the key safety concerns is Unintended Car Movement Protection (UCMP)—a system designed to prevent the elevator car from moving unexpectedly when passengers are entering or exiting. Such unintended motion can pose serious risks, including injury or even fatality. Therefore, reliable and precise testing of the UCMP system is essential to ensure compliance with modern safety standards.
To conduct a comprehensive analysis, engineers used the Dynatronic DE-928U Dynamic Signal Acquisition System along with coded displacement meters, piezoresistive acceleration sensors, and other specialized equipment. These tools were used to capture critical parameters such as:
Car speed and acceleration
Floor displacement
Timing and response of the UCMP activation system
Vibration and dynamic response during fault simulation
The testing reproduced real-world fault scenarios where uncontrolled movement might occur, ensuring that the UCMP system engaged as intended. The DE-928U system proved especially valuable for capturing high-speed, multi-channel data in real time, allowing for accurate signal interpretation and system behavior tracking.
The successful execution of UCMP elevator tests not only demonstrates the robustness of Dynatronic’s measurement solutions but also contributes to public safety and social reassurance. By providing actionable data for system improvement and regulatory compliance, this testing holds significant social and economic value.
Ultimately, these efforts play a crucial role in advancing elevator safety standards, minimizing operational risks, and protecting the well-being of millions who rely on elevators every day.
