Project abstract

 

This collaborative pilot project – involving CENSIS with Topolytics,  CalaChem, Air Monitors Ltd, Falkirk Council, the Scottish Government and the University of St Andrews – aims to enhance decision-making by allowing users to better understand, and have more confidence in, data produced by environmental sensors.

Current sensor systems will detect when there is an issue to be addressed at a particular location; however, they can generate incorrect readings. This may be due to something as innocuous as a bird standing over a sensor or a break in the clouds causing a sudden rise in temperature.

In this pilot project, Topolytics is incorporating statistical models developed by the University of St Andrews into its software. The sensors at Grangemouth are designed to measure sulphate emissions, carbon dioxide levels, wind speed, precipitation, humidity and other meteorological conditions, with the resulting data feeding into the models and then through Topolytics’s dashboard. The aim of the pilot is to enhance Topolytics’s capabilities and improve understanding of the behaviour of environmental monitoring sensors.

Professor Simon Dobson, Director of Research at the University of St Andrews School of Computer Science, explained: “A lot of the data produced by sensors is noise – it’s not always clear how that data should be filtered through into decision-making, which can be tricky in situations where decisive action is required quickly.

“What we’re doing will cut through all that noise and help decision-makers see what they actually need to, if anything at all. The statistical modelling we’re using will be able to identify and eliminate many of the false positives that crop up so frequently – particularly in highly regulated markets such as petrochemicals, which require a great deal of monitoring.”

The pilot project feeds into Topolytics’s ongoing product development, which sees it measure and monitor a growing range of environmental data, including solid waste and recycling, water, effluent and air emissions. The data may be from fixed and mobile sensors/meters, airborne scanners and weighbridges.

Michael Groves, CEO of Topolytics, commented: “Topolytics operates like the best consumer apps – offering an intuitive means by which companies can manage environmental data and generate real time reports. However, while our software offers a window into that data, we need to take some responsibility for its quality. In the case of sensors, we know that they age and degrade, which can complicate decision-making.

“It begs the question: how can you be sure the data being collected really reflects conditions on the ground? St Andrews’ statistical models, combined with our software, can go some way to ensuring that the environmental data is accurate – promoting our aim of offering insight and confidence.

“Environmental monitoring and sensing is a growing market. More sensing, more monitoring, more resource efficiency are the way things are heading – driven by increasingly demanding regulation, rising costs and a desire for transparency. That creates a real opportunity.”
