Automatic Wayside Brake Air Hose Inspection System

LAHView is a wayside brake air hose inspection system designed to operate on passing trains at normal track speeds. Air hose separation is one of the leading causes of train stoppage in North American freight operations. LAHView is a vision based system, which uses a high speed and high definition imaging system to provide high resolution images of every air hose arrangement for inspection and measurement. LAHView provides automated alarms based on the condition of the air hose arrangement and detects the ones that have the highest probability of separation.

Air hose arrangements and their diagnosis can be quite complicated and an automated system can benefit rail operators tremendously.

LAHView is designed to inspect many conditions of the air hose assembly and can detect defects like peaked air hose coupling, air hose height, glad hand angle, air hose angle, coupling position, etc.
