Electric roller shutter door

Abstract

The invention discloses an electric roller shutter door. The electric roller shutter door comprises a single chip microcomputer, a motor, a frequency converter, a feedback module, and a protecting module, wherein the motor, the feedback module and the protecting module are respectively electrically connected with the single chip microcomputer; the motor is used for receiving a signal from the single chip microcomputer to control the lifting of the electric roller shutter door; the feedback module is used for detecting the position of the electric roller shutter door, and feeding back to the single chip microcomputer; the protecting module comprises the frequency converter, an infrared sensor, a smoke sensor, a temperature sensor and a remote controller, and the frequency converter, the infrared sensor, the smoke sensor, the temperature sensor and the remote controller are respectively electrically connected with the single chip microcomputer; the frequency converter is used for controlling the speed of the motor of the roller shutter door; the infrared sensor is used for detecting whether an obstacle exists under the electric roller shutter door or not and outputting a corresponding signal; the smoke sensor is used for detecting the smoke concentration, and outputting a corresponding signal; the temperature sensor is used for detecting the temperature, and outputting a corresponding signal; the remote controller is used for outputting a control signal for the electric roller shutter door.

Description

technical field [0001] The invention belongs to the technical field of rolling door control, in particular to an intelligent detection electric rolling door. Background technique [0002] Rolling shutter doors are installed in residences, banks or shopping malls where the door openings are large and it is inconvenient to install the ground door body. It is connected in series with multi-joint movable doors. Turn up and down. [0003] At present, the rolling door controller lacks an obstacle alarm structure when controlling the lifting of the rolling door. For example, when the rolling door is raised and lowered, there are placed objects or pedestrians below, which makes the rolling door a greater safety hazard. In addition, the existing rolling doors generally can only be raised and lowered slowly at a certain speed. When an emergency occurs, such as an indoor fire, the rolling door cannot be raised or lowered quickly in a short period of time. Contents of the invention ...

Problems solved by technology

[0003] At present, the rolling door controller lacks an obstacle alarm structure when controlling the lifting of the rolling door. For example, when the rolling door is raised and lowered, there are placed objects or pedestrians below, which makes the rolling door a greater safety hazard.

In addition, the existing rolling doors can only be raised and lowered slowly at a certain speed. When an emergency occurs, such as a fire in the room, the rolling door cannot be raised or lowered quickly in a short period of time.
