Within the framework of the CaMéX-IA project, among other things, the “digitization” of machines and locations is carried out. Among the project partners, 10 high schools and 15 educational institutions have committed themselves to selecting at least 2 existing educational institutions, equipping them with sensors and cameras and transmitting the data to the Internet.
Objective: To enable distance learning and to provide datasets that can be used by artificial intelligence algorithms (automatic learning) in the educational context.
A first device begins to transmit data: a table
general low voltage (TGBT) equipped with an energy measurement system
Power, a wireless transmission and a gateway to broadcast
data to an IoT platform.
How it works
The electrical energy measurement system consists of loops of
Rogowski measuring the current in each phase. They are connected to an energy meter that samples and digitizes the readings
and calculates the energy consumed. The result is transmitted via a
Modbus bus to a card equipped with a DASH7 radio chip.
This sends to a DASH7/Ethernet gateway, which transmits the data to an IoT platform using the MQTT protocol. Data is sent in JSON format. The gateway consists of a DASH7 receiver (IOWAY) and a Raspberry Pi for sending via Ethernet or WLAN
MQTT.
The advantage of this system is that the radio gateway is ready and able
Receive the data sent out by the hundreds of sensors of all types
which will measure everyone’s power consumption in a second phase
electrical appliances in the building.
Finally, around fifty devices are to communicate, all technical and educational documentation and all measurement data under free, open source or published
Open data.
