Everybody loves the iconic London bus. But older, diesel-burning London buses are contributing to a serious air pollution problem in the city.
The problem is that new, cleaner buses are expensive – costing as much as £300,000 each – and cannot all be replaced overnight. What to do in the meantime?
Transport for London (TfL) has found a solution: Software AG’s Cumulocity IoT platform, HJS Emission Technology and Sensor-Technik Wiedemann (STW) have teamed up to implement a solution for the remote condition monitoring of exhaust gas treatment systems.
By 2021, more than 5,000 buses in will be retrofitted with HJS Emission Technology’s SCRT (Selective Catalytic Reduction Technology), which uses particle filters and catalytic converters, to reduce soot particles and nitrogen oxide (NOx). (STW) TC1 Telematics Controller (with built-in GPS) will also be fitted onto each bus in order to monitor their emissions at any time or location. And Software AG’s Cumulocity IoT platform will leverage STW’s industrial vehicle specialist solutions, helping them to accelerate innovation.
Pollution kills up to 9,000 people a year in London. In the capital, the most dangerous pollutants include airborne particles and toxic nitrogen dioxide (NO2) gas - both are emitted in vehicle exhaust, especially diesel. TfL and the Mayor of London are aggressively targeting diesel in a bid to eliminate vehicle emissions by 2050.
The UK has some of the highest rates of asthma in Europe and among the highest prevalence rates of asthma symptoms in children worldwide. Diesel-powered vehicles alone are responsible for around 40% of London’s NOx emissions.
Using the Cumulocity IoT, STW and HJS solution, TfL can optimize bus routes, reduce idle times at bus stops, and improve resource allocation. By optimizing the routes, TfL can significantly reduce carbon emissions.
STW has taken Cumulocity IoT and rebranded it “STW machines.cloud” as its IoT solution for the collection of data from on-board devices – it connects, monitors and analyzes operations in real time. Ultimately, HJS can use the data to detect patterns alerting them to problems in either their system or the bus engines.
Each device on board a bus is monitored and tracks engine emissions, but also technical data, faults, routes, locations, and fuel consumption. The data collected can then be visualized using SCADA widgets in real-time and present sophisticated diagnostics enabling real-time updates and calibration.
Implementing algorithms in the telematics modules evolves the big data into smart data, reduces the amount of data transmitted, and enables predictive maintenance -which ensures they can prevent unnecessary actions and breakdowns. STW machines.cloud can be used on a personal computer or mobile device via a web interface.
