Case - Portpay



Construction video


The canals in Amsterdam are navigated by thousands of residents, visitors and tourists every day. To ensure safety and to continue to improve the quality of life, it is necessary to monitor all water movements on the canals and, where necessary, to make adjustments by means of regulation and by tackling nuisance. Portpay is the organisation commissioned by the City of Amsterdam to monitor and manage the canals using an advanced dashboard.



Housing made "transparent


This dashboard is fed with data that comes from smart sensors and cameras that are placed by the company Portpay B.V. Sensors are nowadays very advanced and measure several values at the same time. Through the platform of Portpay B.V., various signals received from the sensors are merged and combined into usable data. By setting certain limit values, system users are steered towards things that deviate from the 'norm'.


All the data together is used for big data analyses and for making improvement proposals. To make the analyses possible, the sensors in the field have to send the collected data to the central database. The data collection is realised by using Wifi, 4G and the in-house LoRa network that Portpay B.V. has rolled out throughout Amsterdam.


Overview of all components



For data collection, Portpay B.V. uses computers with Linux software and cameras that are directed at important junctions along the canals. The system needs to collect data 24 hours a day, 7 days a week, and is powered by LFP battery technology.


In summer, this means that a maximum of 7 hours of charging takes place at night, followed by 17 hours of operation during the day (and therefore discharging).

Elfa developed a stainless steel casing containing a Lithium Iron Phosphate (Lifepo4) battery that is fully compliant with the customer's programme of requirements. Thanks to its high energy density and fast charging time, this battery can continuously supply power to the smart monitoring system during the summer days. The advantages of Lithium Iron Phosphate (Lifepo4) batteries include long life, little or no maintenance, extreme safety, light weight and charging efficiency.
