Introduction
The partner needed to replace the existing street lighting for his customer. There were more than 200 luminaires. The aim was to choose remote-controlled lights, where it is possible to change the intensity of lighting and which have low electricity consumption.
The customer wanted to assign lamps to streets and mark the GPS position of each light pole.
Autonetwork
220 LED lamps with integrated IQRF Lighting bridges were installed in Jirkov city. They installed 3 gateways to power switchboards with respect to the optimal building of the wireless network. Each of them connects between 50 and 90 lights. Gateways are connected to the internet via LTE modems.
The first operation was Autonetwork which connects all powered on lights in street. This operation can be launched directly from the Logimic Light portal and it does not require any user inputs.
They successfully installed gateways with no external antennas. Thanks to IQRF mesh technology you do not have to have direct connectivity of each lamp to the gateway.
Localization
They performed localization which means an assignment of virtual devices in the system to their real locations on poles. For smaller installations, they use a turn on/off method when they manually switch each lamp via the gateway. In this larger deployment, they used the DP2P scan method.
This method uses a special tablet with an IQRF USB dongle and special software SensConnect. The application scans your vicinity and detects just a couple of nearest lamps. You can turn them on/off or send them any command. The USB stick communicates with lights directly so there is no time latency.
Once you localize lamps in your vicinity you can move farther down the street and repeat operation for the next bunch of lights. Once you have lamps assigned to their poles and streets you can assign a control program to each location (street).
Conclusion
The luminaires can be easily upgraded for IoT thanks to IQRF wireless technology, they can be easily managed in a mesh topology, and can be accessed, monitored, and controlled remotely thanks to the gateway.
Logimic has prepared a clear management application that runs on the cloud.
For companies who provide cities and buildings with lighting, Logimic offers assistance in integrating IQRF wireless technology, either through direct integration of IQRF transceivers or using IQRF lighting bridges, or NEMA and Zhaga sockets (to be available soon).
