Function and Working Principle of Elevator Control Cabinet

Functions of elevator control cabinet

1.Control the start, stop, acceleration and deceleration of the elevator: control the operating status of the elevator by receiving floor instructions and speed instructions input by passengers.

2.Safety protection function: When the elevator encounters abnormal conditions such as overspeeding, reaching the top, or squatting to the bottom, the elevator control cabinet can take protective measures to disconnect the power and stop running.

3.Floor display and voice prompts: Install displays inside and outside the elevator to display the current floor and running direction of the elevator. The elevator control cabinet will prompt passengers through voice.

4.Energy management: According to the actual situation, the elevator control cabinet can automatically adjust the elevator's operating mode, such as energy-saving mode and normal mode.

Working principle of elevator control cabinet

1.Receive input signals: The main controller of the elevator control cabinet receives signals from external device buttons and sensors, etc., and converts the signals into a form that the internal processing unit can receive.

2.Processing logical operations: The main controller of the elevator control cabinet processes the input signals and performs logical operations according to the program set in advance to obtain correct control instructions.

3.Sending control instructions: The main controller of the elevator control cabinet sends the processed control instructions to various subsystems, such as the drive system and control system, etc. through the communication interface.

4.Execution of control instructions: After receiving the instructions, the subsystem of the elevator control cabinet begins to execute, such as starting the motor, opening the door, etc.

5.Feedback running status: The subsystem feeds back the data generated during operation to the main controller, such as the elevator's current floor position, speed, fault information, etc. The main controller will adjust the program and parameters based on this feedback information to improve the efficiency and safety of elevator operation.
