Our customer is an EU-based IT enterprise specializing in delivering digital products related to the Internet of Things, Big Data, Machine Learning, and GIS (geographic information system) technologies.

Detailed information about the client cannot be disclosed under the provisions of the NDA.

Challenge

Our client was selected by the municipality of a European city to carry out a software development project of social and state importance. The goal of the project was to build an IoT-based solution to digitize urban infrastructure management, facilitate communication with communities, and improve the delivery of municipal services. The first major software module to be built was a lighting system centralized management. According to the plan of the end client, the city management would decide on the advisability of developing subsequent modules only after the implementation and full placement into the service of the first one.

Our customer contacted Innowise to outsource the development of a smart city IoT application based on the dedicated team model. They commissioned our team to create a lighting system management module. The choice of the client fell on our company, as we had already had a successful history of cooperation in IoT projects.

Solution

Innowise has developed an IIoT-enabled web application for smart city planning and development. We have built and implemented a digital lighting system module, which can be horizontally scaled afterward.

The web app provides centralized control over the lighting system of the entire city. Connected with wireless sensors, the solution collects large volumes of data from city lamps about daily energy consumption, technical condition, working mode, equipment certificate, etc. Users can specify the time for the lights to turn on and off automatically, modify the lighting brightness, and configure the predictive maintenance settings through the app.

In addition to city lights, the system allows controlling and monitoring billboard lighting, building lighting, and the operation of charging stations for electric vehicles.

Users can control the lighting system within several tabs: the map tab, the list of equipment, and the infrastructure maintenance tab. In the smart city app, they can check equipment certificates and create items on the map when new equipment is installed.

The solution also lays the groundwork for improving communication with the communities. We implemented a parser that collected and analyzed reviews and complaints from a municipality portal. Based on this analysis, users can make detailed reports: the number of complaints, the average, minimum, and maximum response time to complaints, etc.

Process

According to the dedicated team outsourcing model, our IT professionals joined the project under the management of the customer’s project manager and business analyst. The workflow was built on Scrum, a widespread Agile software development lifecycle methodology. For task tracking and communication, we used Jira and Microsoft Teams, respectively.

As for the technology stack, we opted for Java for back-end development and Angular for front-end development. The crucial challenge was to integrate the platform with third-party services and unify data streaming processes. We created custom APIs and used Kafka to ensure data processing in a streaming mode without data loss. The solution is compliant with the telemetry standards and EU regulations.

Results

Innowise’s team has effectively addressed the project’s challenges and developed a base module of a smart city web application. We have closely participated in the implementation of the internet of things for smart cities solution. At the moment, more than 300 infrastructure facilities are connected to the system and the application is in practical use.

Our team delivers software maintenance services fixing bugs and enhancing functionality. Shortly, it is planned to develop a strategy for the introduction of new modules: urban security system, traffic control, environmental monitoring, smart parking system, etc. The client intends to continue cooperation with Innowise, as they are completely satisfied with the results of the first stage of the project.
