at least one device, the device being a data source of the data collection network selected from among a machine tool, a household tool, a residential gateway, connected robot, portable device of the Internet of Things, automated guided vehicle, a mixer or food processor, a connected washing machine and an electricity meter, the at least one device being configured to generate data relating to itself, the at least one device being connected to the collection apparatus using a communication network, and
a collection apparatus suitable for collecting data generated by the at least one device,
the network further comprising at least one data-diode-type equipment item respectively associated with the at least one device, so that there are as many data-diode-type equipment items as there are devices within the data collection network, each device being connected to the collection apparatus via its associated data-diode-type equipment item, each data-diode-type equipment item being arranged to render unidirectional the connection between the each device and the collection apparatus, in the direction from the each device towards the collection apparatus so that there are as many data flows rendered unidirectional from each device towards the collection apparatus within the data collection network as there are devices, and
the network further comprising at least one switch configured to selectively activate or deactivate at least one data-diode-type equipment item in order to be able to reestablish, if necessary, a bidirectional connection between the device associated with the data-diode-type equipment item and the collection apparatus.
