A method and device for transmitting data reliably to at least one item of equipment is provided, wherein: from its initial clock H, an item of equipment generates at least one first clock Hfrom a rising edge of the initial clock Hwith a frequency Fand a second clock Hfrom a falling edge of the initial clock H, with a frequency F, the item of equipment: reads the received data using at least one first rising edge of Hand one falling edge consecutive to the first rising edge of H, then reads the received data using a first rising edge of Hand a falling edge consecutive to the first rising edge of H, the four clock edges used being consecutive by 2F, 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.

Method and system for transmitting data reliably

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 &#x394;H between a reference-clock value Hm and the local clock Hi of an equipment, on detecting a phase shift &#x394;H between the reference-clock value and the value of a local clock, when the value of the phase shift &#x394;H 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 &#x394;H 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.
