Task

Automate the inspection of rail-and-sleeper panel assembly: every fastening must be tightened to spec, and output must be recorded without manual notes.

The inspection had to rely on the technical standards chart and work with different types of fastenings.

Client

A railway infrastructure operator. Name under NDA.

What we did and how

We developed a machine vision system that inspects assembly on the line and records the panels.

  1. 01Fastening tightness inspection with millimeter precision
  2. 02Support for five fastening types: KB, FOSSLO, ZhBR-Sh, ARS, Pandrol
  3. 03Checking the assembly against the technical standards chart
  4. 04Automatic recording of assembled 25 m panels
