    • A method is described for the transmission of data among devices (D 1 ,D 2 ,... D i ,... D n ) connected to a communication channel (1) through sequences containing at least two symbols, one dominant ("0") and one recessive ("1 "). According to this transmission method, one (D TSG ) of the devices connected to the communication channel (1) has the function of time slot generator and it transmits on the communication channel (1) with a transmission frequency (f) a sequence of symbols, each defining a time slot in a sequence of time slots. The sequence of symbols comprises at least a series of recessive symbols (" 1 "). When one of the devices (D i ) has to transmit on the communication channel (1), it generates a sequence of symbols, synchronised with the sequence of time slots generated by the time slot generator device (D TSG ) and comprising at least one dominant symbol ("0").
    • 描述了通过连接到通信信道(1)的装置(D1,D2,... Di,... Dn)之间的数据传输的方法,该序列包含至少两个符号,一个占优势(“0”)和 一个隐性(“1”)。 根据该传输方法,连接到通信信道(1)的设备中的一个(DTSG)具有时隙发生器的功能,并且以传输频率(f)在通信信道(1)上发送一系列符号, 每个在时隙序列中定义时隙。 符号序列包括至少一系列隐性符号(“1”)。 当设备(Di)中的一个必须在通信信道(1)上进行发送时,它产生与时隙发生器设备(DTSG)生成的时隙序列同步的符号序列,并且包括至少一个主要符号 ( “0”)。
