AI-Powered Machine Vision to Detect Assembly Errors, Missing Components, and Wiring Defects

Control Panel Inspection

Elevator systems rely heavily on two critical electrical assemblies:

1. The Elevator Car Operating Panel (COP)

The user-facing control interface inside the lift car

2. The Elevator Controller Panel Box

The central control unit that manages motor drives, communication, sensors, safety circuits, door controllers, emergency functions, and overall lift operation

Any assembly error, missing component, or wiring mistake inside these panels can lead to operational failures, false signals, safety hazards, and field breakdowns.

Traditional manual inspection methods are slow, operator-dependent, and prone to error—especially as modern elevator panels contain hundreds of terminals, controllers, PCBs, relays, safety modules, and wiring routes.

Intelgic's AI-driven machine vision inspection system brings accuracy, consistency, and real-time intelligence to panel manufacturing—ensuring zero-defect electrical panels for elevators.

Why Automated Inspection Is Critical for Elevator Panels

1. High Component Density

COPs and controller panels house:

  • PCBs
  • Terminal blocks
  • Wiring harnesses
  • Emergency switches
  • Displays & HMI units
  • Sensor interfaces
  • Relays & contactors
  • Power supplies
  • Fuses & breakers
  • Safety modules

Manually verifying every connection and component is nearly impossible without automation.

2. Strict Safety Requirements

Elevators must comply with:

  • EN 81
  • ASME A17.1
  • ISO safety standards
  • Fire & emergency safety systems

A missing wire or wrong connection can compromise passenger safety.

3. Global Quality Expectations

Elevator OEMs and maintenance companies demand zero-failure electrical systems to reduce downtime and service calls.

Our AI inspection system ensures 100% component and wiring verification with detailed digital reports for compliance and quality assurance.

Advanced Inspection Features

3. Region-Based Inspection for Better Accuracy

Intelgic divides the panel into region-specific zones:

Power section
Safety circuit section
Communication block
Door control section
Terminal strip
PCB region
UI/HMI region
Emergency circuit section

Each zone has its own rules and logic, ensuring high accuracy in detecting errors.

4. AI-Powered Learning from Good Panels

Intelgic's system can create Golden Templates by analyzing defect-free panels.

The AI learns:

Layout
Component shapes
Wiring routes
Connector positions
Color patterns

Future panels are compared against this golden standard for defect detection.

5. Automated Reporting & Digital Quality Certificate (DQC)

After inspection, the system generates:

Defect map (highlighted on images)
Component-level pass/fail report
Wiring validation report
Images for traceability
Timestamp and operator data
Digital Quality Certificate (for passed panels)

Reports can be integrated with:

MES ERP QC systems Cloud dashboards
