The All Electric Society Park

Customer profile


The AES Park

Phoenix Contact

  • Covering more than 7,800 m², the All Electric Society Park illustrates how renewable energy can be generated, converted, stored, distributed, and used.
  • 550 solar panels and other power generators supply the park with energy.
  • We demonstrate the efficient use of energy based on e-mobility, smart buildings, transportation infrastructure, and production facilities.

The challenge


Soil moisture check

Individual irrigation requirements involving a high level of plant care

In the All Electric Society Park, there are numerous green spaces with plants that need a reliable water supply. There are different irrigation requirements depending on the water required by the respective plant species and weather influences such as sunlight or rainfall.

Optimum manual irrigation is very labor-intensive and cost-intensive. Furthermore, it is difficult to monitor consumption.

The solution


Soil moisture sensor

On-demand and resource-efficient irrigation

The park’s green spaces have been divided into 15 irrigation zones for optimal irrigation. Each zone has been equipped with battery-powered LoRaWAN soil moisture sensors.

The sensors measure the soil moisture and temperature as well as the conductivity at fixed intervals and then send the data to the company’s own IoT platform via a LoRaWAN gateway. The soil measurement data and the data from the local weather station are combined in the cloud. Depending on weather reports, on-demand irrigation can then be planned or preset based on various parameters.

As the water meter is connected digitally, important information on the current flow rate and water consumption is taken into account by the irrigation control system.

Control of irrigation via the cloud

A combination of PLCnext and LoRaWAN technology is used for the smart irrigation solution. All the necessary data in the cloud for efficient irrigation control is combined via the automation system. The PLCnext Control continuously compares the current sensor values with the preconfigured cloud parameters. If the algorithm determines that a green space is too dry, the solenoid valve for the corresponding irrigation zone is opened automatically. As soon as the specified amount of water has been reached or the soil moisture has returned to normal, the valve is closed again. If the local weather station detects a rain event based on the data, the irrigation process is automatically canceled.

Our own IoT platform enables users to locate the environmental sensors on a map and display the collected measurement data clearly in individual diagrams.

Local controller in the AES Park

A local operator terminal allows the times when an irrigation process may be started to be defined individually for each day of the week. Here, the user can also enter the limit values for the individual irrigation zones. For time synchronization, a GNSS (Global Navigation Satellite System) receiver with integrated NTP (Network Time Protocol) server is queried. The software also reliably detects leaks in the system and generates alerts. Furthermore, the PLCnext Control is connected to Resylive, the web-based SCADA system from Phoenix Contact, via a VPN (Virtual Private Network) tunnel. The system can be configured, controlled, and monitored remotely or locally at any time using this platform. It is also possible to create reports on water consumption.

LoRaWAN (Long Range Wide Area Network) wireless network technology is used for data communication. The technology is characterized by a high reception range and low energy consumption. These properties are particularly suitable for IoT applications in urban areas. Depending on the type of building, LoRaWAN has a range of up to five kilometers in urban areas and up to 15 kilometers in rural areas. The technology uses the license-free 868 MHz ISM frequency band for data transmission.

The LoRaWAN sensors installed in the field send the current measured values to the nearest gateways at specified intervals. From there, the data is forwarded to a network server via a cellular or Ethernet connection.

Intelligent environmental management with the Smart City Box

With the Smart City Box, you can easily combine city data – from the sensor to the control system. Data transparency helps cities identify targeted optimization measures for efficient and sustainable living spaces. The all-purpose box is easily connected to your existing infrastructure.

All applications are based on sensor data and wireless data transmission acquired in real time. Given its open system architecture, the Box can be easily integrated into both municipal computing centers and into many other IoT platforms.

Software for environmental data visualization
The Environmental Monitoring Service enables complete remote monitoring of environmental data via a web portal. All sensors and measured values can be integrated easily. The software reliably detects leaks in the system. Upon identification, automatic alerts are generated.

Soil moisture sensors
LoRaWAN soil moisture sensors measure the moisture, temperature, and conductivity of the soil. The sensor data is sent to the cloud platform via LoRaWAN. The data can then be used for sustainable environmental monitoring.

LoRaWAN gateways
The LoRaWAN gateways forward the measured values from the sensors to a network server via a cellular or Ethernet connection. The server makes the user data available to an application server. Both servers can be installed locally or located in the cloud.

PLCnext Control
At the heart of the control cabinet is an AXC-F 3152 PLCnext Control, to which I/O modules from the Smart Elements product family are connected, which are used to control the solenoid valves. All the necessary data for efficient irrigation control is combined in the PLC.

Summary


Irrigation in the All Electric Society Park

Water savings of up to 30%

The smart irrigation solution in the All Electric Society Park shows how different plants, trees, and grasses can be watered in an on-demand and resource-efficient way. Water savings of up to 30% can be achieved compared to simple time-controlled irrigation.

This example can also be easily applied to other urban areas. The data can also be easily integrated into existing control systems.
