Abstract: Method and system for synchronizing a plurality of pieces of equipment, wherein it includes at least the following steps: in each equipment generating the command signal, computing a value of the difference ΔH between a reference-clock value Hm and the local clock Hi of an equipment, on detecting a phase shift ΔH between the reference-clock value and the value of a local clock, when the value of the phase shift ΔH between the local clock and the reference clock corresponds to one refresh cycle of the reference clock Hm, a corrected clock time Hic is defined by repeating a number of the clock signal of given parity if the value of the local clock is early and a corrected clock time is defined by skipping one number of the clock signal of opposite parity to the first parity if the local clock value is late, when the value of the phase shift ΔH is higher than one refresh cycle, the method resets the reference time, a corrected value of the clock in each equipment is used to emit the command signal.

Abstract: A method and device for transmitting data reliably to at least one item of equipment is provided, wherein: from its initial clock H1, an item of equipment generates at least one first clock H1U from a rising edge of the initial clock H1 with a frequency F1U and a second clock H1D from a falling edge of the initial clock H1, with a frequency F1D, the item of equipment: reads the received data using at least one first rising edge of H1U and one falling edge consecutive to the first rising edge of H1U, then reads the received data using a first rising edge of H1D and a falling edge consecutive to the first rising edge of H1D, the four clock edges used being consecutive by 2F1, decodes at least the four messages using an error-correcting code, when at least one decoded message is correct, it uses the information contained in this message to drive a device linked to said item of equipment.
