Datek Light Control

Some of our projects

Technology

Norwegian-developed technology

Our lighting control system has been developed entirely by Datek. All further development and support take place from our premises/office in Lillestrøm, just outside Oslo.

With ownership and expertise at all stages of the design, we can offer standard systems as well as customer-specific applications without dependencies to third parties. It provides good flexibility for our customers and is a guarantee of investing in a system that develops in line with the market, customer needs and regulatory requirements.

Built as an IoT solution from the ground up, the devices communicate with each other in the cloud. The system enables protected and controlled access for the individual user with their rights and needs – easily and seamlessly.

All devices can be upgraded remotely (OTA) with improvements and new features or special solutions so that the customer is well equipped for the future.

About the system

Outdoor lighting control system

Datek lighting control is a control and monitoring system for outdoor lighting systems. The system is designed to optimize energy use, streamline operation and maintenance, and minimize unwanted light pollution.

Zigbee technology

We have been working with Zigbee since 2006.  Zigbee is a wireless protocol used in a variety of industries and technologies within the Internet of Things (IoT).

Language is used to get things to talk to each other. Some of the advantages are a very low power consumption and long range. This makes Zigbee suitable for battery-powered equipment.

How it works

The control units placed in the field are always connected and provide full control with continuous feedback on status. Our lighting control units are integrated externally or internally in the luminaire. They can also be mounted on a pole, in a junction box or a road lighting cabinet.

The solution is suitable for both new systems with modern dimmable LED light sources or for traditional contact-controlled street lighting cabinets. The system continuously reflects the actual conditions in the field; therefore a map-based user interface is used to configure lighting profiles based on function and exact positioning.

Full control

The control regime is based on rule sets that run in a secure, cloud-based server solution. The dimming level control signals can be almost anything. In its simplest form, it is a table that follows sunrise and sunset based on geographical location.

For more precise light level control that considers local conditions, a LUX meter can be used. The system also provides the option of SMS messages in the event of alarms, or notification by e-mail for specific events.

Data is collected and stored in a data centre, and extensive logging allows for many different reports on historical data and events.

Customised lighting control

The lighting management system is an IoT (Internet of Things) system where the devices communicate via the cloud. Users get needs-based rights and secure access, everything is easily controlled via web portal or mobile.

A football coach who wants to switch from training lights to match lights, or a fitter who wants to turn on a system during the day for necessary maintenance, can both use a simple app on their mobile phone.

With a robustly built communication chain, all units have built-in procedures for how to act if any link in the chain falls out. This prevents downtime, and as long as the lamp has power, safety mechanisms ensure that it lights up.

Reliability and uptime

Zigbee is a radio standard for large networks with many devices. The network is based on a proven technology with a MESH structure that means that all control units in the luminaires contribute to a stable radio link in the area. MESH works so that the signals jump from luminaire to luminaire on their way to their destination, usually a radio coordinator placed in a gateway in a VTP. If a control unit is lost, the signal automatically chooses a different route to its destination.

We often build our networks with multiple- coordinators for extended operational reliability. Our solutions scale efficiently, and we currently operate single networks with many thousands of nodes.

Communication between the gateway and the central system takes place via GPRS, 3G, 4G and alternatively via TCPIP over LAN or fiber if available. In the event of a fault in the GPRS network, SMS can be used to control the light.

Our choice of Zigbee as a protocol is due, in addition to the flexibility it provides, to the desire for maximum reliability.
Zigbee creates an encrypted communication between the gateway and luminaire devices via 2.4 GHz radio technology and follows the IEEE 802.15.4 standard.  

Regular data transfer

Some data is routinely transferred at fixed and/or configurable intervals, while the transfer of other data is event-based or transmitted when there is a change in value.

In addition to the regular transfer of data to the server, data can also be requested when needed from the server, such as user-initiated requests. There is a separate regime for the collection of certified meter readings for consumption measurement.

If one or more parts of the communication line drop out, the system begins several parallel runs to ensure the operation of the solution. If a unit has not reported at the expected interval, repeated attempts will be made to establish contact. If this does not lead to this, an alarm will be generated after a defined period.
