CNets subsidiary Checkwatt provides the energy management system (EMS) for a 1MWh battery storage in Varberg. The system handles communication and control of the battery storage on site. This Container sized unit is the first step of a larger battery warehouse that is planned to be operational by 2023. CheckWatt’s cooperation partner Solkompaniet delivers and installs the main battery. A platform from Ntricity handles trades with Svenska Kraftnät.
Varberg Energi wants to develop and offer new services to customers. The battery warehouse is an investment to complement the existing energy system to strengthen the power balance and grid stability in general and to make the energy system more flexible and sustainable.
CNet has joined the European project RESPONSE which aims to establish a strategic vision for Smart Cities Energy Transition: Climate-neutral cities by 2050.
The project aims to make energy sustainability reality by solving the energy trilemma (security, equity/affordability, environmental sustainability) at building, block and district levels in smart cities. The project builds upon intelligent integrated and interconnected energy systems coupled with demand-oriented city infrastructures, governance models and services that foster energy sustainability.
CNets subsidary IoT BRIDGE welcomes a new member to the team, Jacob Nyman.
Mr. Nyman, who majored at KTH, School of Electrical Engineering and Computer Science (EECS) specializes in machine learning and will complement the teams expertise which consists of experienced IoT as well as cloud architects and developers, bridge construction scientists, sensor instrumentation experts and business and process developers.
Our goal is to advance the digitization of bridge operation and maintenance and to contribute to the renewal and better use of the Swedish and European transport infrastructure.
CNets has sponsored a master thesis analyzing a new method to create a health indicator for machines. The master thesis was handed in and evaluated by KTHs School of Electrical Engineering and Computer Sciences (EECS).
The work is based on distance measurements transformed into a vector space through a feed-forward neural network. The neural network is trained using a multi-objective optimization algorithm to optimize criteria that are desired in a health indicator. The constructed health indicator is used as input to a gated recurrent unit (a neural network that handles sequential data) to predict the remaining life of a system in question.
The Master thesis Machinery Health Indicator Construction using Multi-objective Genetic Algorithm Optimization of a Feed-forward Neural Network based on Distance was carried out by Jacob Nyman in the field of machine learning:
CNets has sponsored a bachelor thesis targeting the integration of the Keto-Mojo glucose meter into the LinkWatch eHealth platform. The thesis was handed in and evaluated at KTHs School of Engineering Sciences in Chemistry, Biotechnology and Health (CBH).
As different medical products send data to their own platforms, it becomes challenging for both patient and care provider to take and keep track of all available vital parameters. This lack of a universal platform connecting to devices of different manufacturers, combining all available data has been the initial motivation to develop LinkWatch. It provides a platform where all the patient’s medical measurements can be collected and visualized. The mobile application, developed both for iOS and Android have been programmed in Kotlin and Swift to provide a secure and efficient data transfer between the blood glucose meter and LinkWatch’s web server. The mobile application can connect to the blood glucose meter with Bluetooth and transfer its measurements to the LinkWatch’s web server. When the records are stored in the LinkWatch system, the patient can see their glucose levels along with other vital parameters.
The bachelor thesis Integrering av glukosmätare med molntjänst för hemmonitorering was carried out by:
The work was submitted to the KTH, School of Engineering Sciences in Chemistry, Biotechnology and Health (CBH), Biomedical Engineering and Health Systems in 2021 in Swedish:
Air pollution induced respiratory diseases are rapidly increasing in large cities. Treatment of diseases caused by air pollution is estimated to cost approximately 2% of GDP in developed countries and 5% in developing countries. AsthmaWatch, developed in the GOEASY project incorporates a Galileo based secure mobile air quality monitoring platform into a mobile smartphone app that enables users to identify places and pollutants that they can avoid. Every day outdoor air quality changes on a street-by-street basis. By crowdsourcing air quality information from mobile sensors, the app helps citizens proactively avoid unhealthy environments.
Pollution varies in location and distribution strongly related to the weather and people suffering from Asthma or from pollen allergies can use detailed forecast data to avoid highly polluted areas to avoid negative impacts on their health. AsthmaWatch visualizes measured pollution for the Stockholm area providing detailed forecasts and rout recommendations based on pollution data:
Monday the 21st of June CNets subsidiary IoTBridge organizes a Webinar in cooperation with Stockholm cities Trafikkontoret: “Digitalt beslutsstöd för komplex broinfrastruktur i urbana regioner” at 09:00-11:30 o-clock.
The event targets stakeholders related to bridge maintenance to introduce new digital solutions for bridge managements and maintenance.
The event will feature the following presentations on Swedish:
Utmaningar vid förvaltning av åldrande och komplex infrastruktur i täta regioner, Jonas Loberg, Enhetschef Anläggning på Trafikkontoret Stockholm stad.
Plattform för digitalt beslutsstöd; Peter Rosengren & John Leander, IoTBridge AB.
Broarna i Göteborg – Status och erfarenheter av ny och gammal broinfrastruktur; Mikael Andersson, Trafikkontoret Göteborg.
Övervakning av broar i dag och i framtiden; Tony Janhunen, Department Manager, Ramboll.
CNet has developed a Sensor field kit to monitor air pollutants within urban areas. The field kits can measure different pollutants and transmit their location where the measurement is taken to visualize the current level of different pollutants within the area. The data is stored and the GoEasy App can visualize historical readings at different points-of-interest. The new generation of field kits can measure small and larger particles as well as NO2 and are can be used walking, cycling or motorized modes of transportation. The field kits run on an external batteries which enables measuring and transmitting data for several days. The new generation of field kits will be deployed in a Pilot in Stockholm collecting data to generate a pollution map of the city.
African countries face the need to meet a fast-growing energy demand but its nations can pick from a portfolio rich in renewable energy sources, including water, sun and wind, among others. Building on experience gathered around the globe Africa can design it’s energy sector for the future.
Half of the continent has solar radiation intensities of more than 7000 kWh/m2/day, the perfect premise for utilizing solar power. Renewable energy sources offer additionally more independence from fossil material, improved resilience and sustainability.
CheckWatt, one of CNets subsidiaries, offers configurable energy related solutions for different needs. In the last year CheckWatt has extended their business to Europe. The companies expertise and experience is leading in the Swedish market and internationally competitive. CheckWatt is proud to announce that they have entered their first contract in Kenya, which entails the deployment of a new solar energy installation in Kenya.
