Method and system for transmitting data reliably

Abstract

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.
