RCMs Architecture for London Underground
RCMs server based solution for London Underground uses Mango as a data store and alarm generation middleware.
RCM are an industrial monitoring service provider in the UK. Beginning life as a product design team at an electronics manufacturer (DVR Ltd), they chose to specialize in Remote Condition Monitoring. Using their wide ranging skill set, they develop and manufacture complete monitoring solutions from the data collection hardware all they way through to front end software.
RCM utilize the power of Mango from Infinite Automation Systems to capture and analyze 8 million data points per day from safety systems on London Underground. Their work is helping to reduce the number and duration of line closures on a rail network that transports millions of people every day.
Insights into the failure modes of axle counters have been gained that were not possible before. Though investigation of past hardware failures, it is now possible to recognize and prevent failures or enhance readiness to deal with them when they occur.
Working together, RCM and London Underground have evolved their understanding of how to look after the axle counters they monitor. Using advanced techniques, they're able to provide real time alerts and profile individual devices to detect gradual deterioration that may indicate the need for maintenance.
London Underground are improving over all reliability while spending less time performing maintenance. Technicians can now be directed to axle counters most in need of maintenance instead of needlessly interfering with devices in good working order.
To achieve these goals, RCM built a modern web based software package that integrates asset management and monitoring. Taking advantage of Mangos RESTful API, their initiative systems are tailored to enable end users to enter devices, attach monitoring equipment and start collecting data without assistance or complicated configuration.
This is a screen capture of the asset monitor software in use. Included below are some screenshots which are all self-explanatory. The core of the software is an asset management system to which we can add plug-in modules. The ‘now’ and ‘history’ screens shown are provided by a plug-in for EAK monitoring. This allows us to provide customized solutions to other clients for monitoring any other device types.
What RCM have to say about Mango:
"To provide London Underground with the service they require, we needed to partner with a forward thinking data storage and analytics solution provider. Mangos real time API makes what we do possible. Mango has proven to be a robust, high performance data storage solution.
And Mango has helped me in ways I never expected it to. The charting, real time watch lists and administration capabilities of the Mango web interface have been a real help to us while developing of our own front end. They help us understand the data we collect so we have been better at focusing our front end on showing London Underground technicians what is important to them.
"Automated incremental back ups and low resource usage keep our systems administrators happy too. All in all, we're very happy with the software and support we receive from Infinite Automation."
