IEM Developing Comprehensive Real Time Monitoring System for Major Transit System,   
Monday, May 09, 2016

TROY, NY - IEM Corporation, a worldwide leader in the development and production of innovative sensor-based systems for the intelligent transportation industry, has partnered with a major US city transit system to develop a comprehensive technology for continual monitoring of rail activities.

Rail and transit operations in urban settings often generate noise, vibration, and other impacts that may adversely affect residents and businesses along the rail route. Beginning with patent-pending methods for flat spot detections – a common source of unwanted noise and vibration – and measurement of ground vibration, this technology has the capability of integrating many different sensor modalities at multiple locations to provide for detailed detection, tracking, and analysis of anomalous conditions and automatically implement a mitigation program to correct them.

While modern rail operations include many measures to reduce the impacts of vibration, real time performance monitoring can identify associated noise and ground movement which can impact sensitive communities and facilities. Such rail corridors include hospitals and research operations containing vibration-sensitive equipment, museums with fragile collections and concert halls designed to optimize sound.

The IEM system integrates “smart objects” (such as geophones, accelerometers and acoustic sensors) that can sense, analyze and automate machine-to-machine communications. Configuring additional modular sensors expands the reach of the system.

Data from the sensors are housed on a system of servers with web-based access, enabling users with varied use needs to recover the information in formats that best suit them. Analysis of this data may be used to modify operating conditions in sensitive areas, such as reducing train speed.

Established in 1987, IEM has more than 25 years of transportation safety and security experience. Initially founded to manufacture and market its original electronic wheel gauge for the railway industry, IEM has expanded its core business to include a range of hand-held and in-track devices for railroad inspection, as well as optical and acoustic monitoring solutions for government and industrial partners around the globe.
