The invention enables fault-tolerant synchronisation of real-time equipment (11, 21, 22) connected to a computer network (41) over several tens of metres, with the option of including or not such equipment in the synchronisation device. The invention provides global scheduling of the real-time computer platform in the form of minor and major cycles in order to reduce the waiting time during sensor acquisition, associated calculation and preparation of the output towards the actuator in an integrated modular avionic architecture (IMA). For this purpose, the invention uses a synchronisation bus (61) which is separate from the data transfer network (41) and circuits (113, 213, 223) that interface with said specific bus (61) in order to process the synchronisation signals from the real-time local clocks (112, 212, 222) at each piece of equipment (11, 21, 22) in a fault-tolerant, decentralised manner.
