MRT trains move over half the Singapore population every day, place to place, empowering the conduct of everyday activities. There is little margin for error. SMRT – one of the two rail operators in Singapore – harnesses technology to ensure reliability.
SENSORS AS A MONITORING DEVICE
Trains draw power from the power rail through train-mounted current collector device (CCD) shoes. If the power rail sags below an acceptable limit, a power disruption could be triggered. The sensors, which sit in tandem with the CCD shoes, measure the dynamic readings and ensure that the data, with variations as small as 1mm, are within safety thresholds. These mechanical sensors, which are currently mounted on five trains on the North-South and East-West Lines (NSEWL), monitor the condition of the power rail during service hours. In 2016, about half of all SMS alerts that were triggered prompted immediate rectification work.
EMPLOYING SENSORS FOR “SENSE-MAKING”
All data collected weekly is plotted against data from previous weeks, allowing identification of preventive maintenance required for power rail segments. These sensors supplement the multifunctional vehicle (MFV) that circulates the entire track during engineering hours between 1am and 4am, collecting information on 16 parameters relating to the track and the power rail. One MFV takes about four to six months to cover the entire NSEWL.
Many of us would have grown up with libraries playing a big part in our lives. Against the backdrop of an increasingly affluent society and convenient access to abundant reading materials...
TECHNOLOGY AS AN ENABLER TO BETTER USERS’ EXPERIENCE
Managing a network of 26 public libraries across the island, the National Library Board (NLB) has consistently focused on adopting technology to transform well-used, process-heavy services, by shifting service delivery away from manual touch points and towards technology-driven interfaces. NLB was one of the first libraries in the world to implement Radio Frequency Identification (RFID) to track the movement of library items. This transformation enabled our users to check-out and return items independently. Self-checkout stations, which were introduced to public libraries in 1998, reduced the time needed to borrow a library item from 45 to less than 5 minutes. Subsequently, transaction kiosks known as eKiosks provided a one-stop, self-service platform for a variety of transactional and payment functions. Users not only enjoyed significant time savings but were also able to complete more transactions on their own.
BEYOND PHYSICAL LIBRARY SPACES
Recognising that Singapore has one of the world’s highest mobile penetration rates1 averaging 149.2% between July to December 2016, it was evident that library service innovations should be adapted to a digital lifestyle through extended offerings to the online space.
