Elevator Electric Component

The elevator electrical control system is the logical command center for elevator operation, primarily composed of the following core modules working together:

Core Control Unit

★ Logic Controller

PLC (Programmable Logic Controller): Processes elevator call commands, leveling signals, and operating logic, coordinating drive and door operator actions (such as responding to floor calls and direct drive).

Relay Control System: Early relay combinations were used for logic analysis, but contacts are prone to wear and high maintenance costs.

Microcomputer Control System: Replaces hardware logic with software programming, improving flexibility and reliability.

Human-Machine Interface Components

★ Operation Terminal

Cabin Control Panel: Internal selection buttons, door opening and closing controls, and operating status display.

Hall Call Device: Floor call registration and direction indicators.

Touch Screen: Provides a visual operating interface (new system integration).

★ Feedback Device

Leveling Sensor: A magnetic sensor plate and magnetic isolation plate work together to ensure a landing accuracy error of ≤5mm.

Weighing Sensor: Triggers an alarm and prohibits startup in the event of an overload.

Drive Execution Module

★ Speed Control System

VVVF Frequency Converter: Adjusts the voltage and frequency of the traction motor to achieve stepless speed change from 0-5m/s.

Closed-Loop Control: A rotary encoder and PG cabind provide real-time feedback on the cabin position, dynamically adjusting the speed curve.

★ Door Motor Control

The door motor drives the cabin door/landing door to open and close (≤3 seconds). The door interlock contacts ensure an engagement depth of ≥7mm before operation is permitted.

Safety Protection Circuit

Protection Mechanisms	Functionality‌
Emergency Stop	Cabin roof/pit emergency stop switches immediately cut off control power.
Terminal Offset Protection	Limit switches → limit switches gradually cut off power and brake.
Phase Sequence Protection	Relay locks the system in the event of phase mismatch or loss.
Access Control and Elevator Control	Floor access control via IC cabind/biometric recognition (face, fingerprint). Fire mode automatically removes restrictions.

Key Technical Points for Maintenance

Contact Maintenance

Regularly clean relay and door interlock contacts to prevent oxidation and false contact failures.

‌Heat Dissipation Management

If the control cabinet temperature exceeds 30°C, activate the heat dissipation device to prevent overheating of the PLC or inverter.

Program Backup‌

Microcomputer system software must be regularly updated and a copy of the logic program must be saved.

Note: Modern systems tend to adopt an integrated "PLC + inverter + smart access control" architecture, supporting three operating modes (driverless, driver-operated, and fire protection). Redundant design ensures safe shutdown even in the event of a single point of failure.

Introduction

Elevator Electric Component refer to the collection of electrical parts that control and drive the operation of an elevator. They mainly include the elevator controller, drive motor and frequency converter, buttons and signal panels, safety relays and sensors, as well as door operators and limit switches. These components control the elevator's speed, acceleration, deceleration, door operation, and emergency stop.
