In the elevator, it is called a system that is used to accurately approach the cabin to the desired floor. This system makes the elevator move smoother and more precise, especially in the final stages of the stop.
The key differences of the elevator with Eprouge system:
1. Smooth stop: elevators with Eproge system reduce their speed gradually when approaching the floor and stop softly and without shock.
2. Accuracy in stopping: this system makes the cabin stand exactly level with the floor and the difference in height is minimized. 3. Increased comfort and safety: due to the smooth movement, passengers get on and off more easily and safely. 4. Depreciation reduction: The smoothness of movement and stopping reduces the depreciation of the mechanical parts of the elevator Using a combination of advanced sensors and controllers, the Eproge system in the elevator precisely controls the movement of the cabin near the target floor. This system is commonly used in modern elevators with VVVF (variable voltage and frequency) drives. How the Eprouj system works technically: 1. Positioning sensors: These sensors detect the exact position of the cabin relative to the floor. Magnetic or optical sensors are used that interact with markers installed in the elevator shaft. 2. Speed and acceleration control: when the cabin gets close to the floor, the Eproge system will gradually reduce the speed. This is done by adjusting the frequency and voltage of the motor through the VVVF drive. 3. Accurate leveling: In the final stage, the Eproge system adjusts the position of the cabin with millimeter precision so that the floor of the cabin is completely level with the floor of the floor. 4. Soft braking: Unlike the old systems where the brakes worked suddenly, the Eproge system applies the brakes gradually to reduce shock and sudden movements. 5. Reducing energy consumption: due to the optimal control of speed and acceleration, this system reduces the energy consumption of the elevator motor. Advantages: • Increased passenger comfort due to smooth movement and stopping. • Increased safety by preventing the level difference between the cabin and the floor. • Reduced depreciation of mechanical parts due to more uniform movement.
