Energy efficiency

Industrial buildings

Identify where, when, and how energy is consumed and then determine the energy saving measures to be put in place.

CHALLENGE

In an industrial building, there are many sources of consumption. The diversity of these sources of overconsumption can lead to significant energy expenditure. The major challenge for managers in industrial buildings (factories, airports, ports, hospitals, etc.) is to identify where the largest items of expenditure are located in their building and to optimise the operation of the equipment in question. It is essential for them to have tools that enable to:

- to understand and visualise the energy profile of the equipment and the building,
- define objectives to be achieved/KPIs (Key Performance Indicators),
- improve energy budgeting,
- optimise the organisation through better capacity usage, reduced maintenance or labour.

SOLUTION

To meet these objectives and automate the collection of consumption data, the IoT is THE solution. Easy and quick to deploy, IoT does not require the implementation of a heavy infrastructure to operate. So, to optimise its energy expenditure, the first step is to collect and analyse consumption data. To do this, it is necessary to set up all the elements of the IoT data value chain:

- Adeunis’ sensors to collect data,
- connectivity to transmit this data,
- an application to analyse the data and issue recommendations.

Focus on the Adeunis / Actility / Opinum solution that guarantees a complete IoT chain.

ADEUNIS

Energy data collection (water, gas, electricity, thermal) is carried out using IoT adeunis sensors connected to the industrial equipment to be supervised. They monitor the evolution of fluids, detect overconsumption and alert in case of leaks.

Actility

The indoor/outdoor gateways receive the data transmitted by the Adeunis’ sensors and relay it to the ThingPark enterprise server via the LoRaWAN Actility network.

Actility

The server processes the data from the Adeunis’ IoT sensors and relays it in real time to the associated applications.

Opinum

The data sent in the Opinum application which carries out automated procedures: viewing the data chronologically, editing reports, sending notifications, etc.

Examples of application cases in industry:

Operation of a machine Monitoring of electricity consumption

The IoT solution used makes it possible to monitor the evolution of electricity consumption and to detect possible points of over-consumption.

By analysing this data, it is then possible to detect points of improvement and to define an action plan to reduce consumption on a long-term basis.

Adeunis MODBUS device

The Modbus interface, which acts as a Modbus master, manages up to 20 slaves connected to a wired bus (RS232/RS485) in RTU (Remote Terminal Unit) mode. It allows the registers in the monitored MODBUS devices to be read and written through the LoRaWAN network.

The building - Analysis of water consumption

An analysis of water consumption enables sources of savings to be identified.

The alert function in the event of overconsumption synonymous with potential leaks, allows you to act as quickly as possible to resolve the malfunction and thus avoid material and financial losses.

Adeunis PULSE device

The PULSE sensor is directly connected to a machine or meter and counts the electrical pulses generated. The data is then communicated at a programmable frequency (e.g. every hour) via the LoRaWAN network.
