Classification and Fault Analysis of Common Electric Rolling Doors

The electric rolling shutter is integrated with a multi-joint movable door system, ensuring smooth and efficient operation. The motor unit powers the starting motor, which drives the entire mechanism. In the fixed slide structure, both the upper and lower doors rotate around a reel located above the door. The electric shutter motor is hidden inside a coiled tube, and as the motor rotates, it drives the drive shaft, enabling the roller blind to lift and lower. When the curtain is raised, it winds around the reel, and when lowered, it slides down along the inner side of the guide rail. The system is controlled via a remote controller, allowing users to easily raise, stop, or lower the curtains. Additionally, a manual release system is available in case of power outages, enabling the shutter to be operated using a manual crank. This type of door is ideal for commercial buildings, garages, shopping malls, hospitals, factories, and mines, as well as residential areas. It's especially suitable for large door openings where traditional ground-level doors may be inconvenient, such as in garages, shopping centers, fire shutters, and hangar doors.

Electric roller shutters come in various types based on materials and functions:

1. **Material-Based Classification**: These include European-style rolling doors, inorganic fabric-type, mesh-type, aluminum alloy-type, and crystal rolling doors. Each material offers different durability, aesthetics, and performance characteristics.

2. **Motor Type Classification**: Different motors are used depending on the application. Examples include fire-rated roller door motors, Australian-style motors, external roll motors, tubular motors, double-curtain motors, and high-speed roll motors. Each motor type has unique features tailored to specific user needs.

3. **Function-Based Classification**: Based on user requirements, there are silent, noise-reducing, stainless steel, windproof, fire-resistant, and transparent crystal shutters. These options provide enhanced functionality and adaptability for different environments.

Several factors can lead to long-distance operation failure in electric roller shutters:

1. **Power Transmission**: If the transmission power is high over a long distance, it can cause excessive energy consumption and signal interference.

2. **Receiving Sensitivity**: Increasing the receiver’s sensitivity can extend the remote control range, but it also makes the system more prone to interference or loss of control.

3. **Antenna Design**: Using linear antennas that are parallel to each other can increase the remote control distance. Extending and straightening the antenna can further improve signal strength.

4. **Antenna Height**: The higher the antenna, the farther the remote control signal can reach. However, this is often limited by physical constraints.

5. **Obstruction**: Most wireless remote controls use UHF frequency bands, which behave similarly to light—propagating in straight lines with minimal diffraction. If there are walls or other obstacles between the transmitter and receiver, the signal strength can significantly decrease. Reinforced concrete walls, in particular, absorb electromagnetic waves due to their conductive nature, leading to reduced performance.
