1. , in distributed process control system, transmits a kind of method of data between a plurality of stations effectively, comprise the following steps:

  • At least data are divided into the first kind and secondary sources at each station;

    Above-mentioned primary sources are appointed as rapid data;

    It is characterized in that;

    One of preliminary election is target regularly, with this regularly target must all this rapid datas at the part station at a plurality of stations be upgraded at least;

    Calculate the time of a reality, this rapid data upgraded with this time;

    Determine this timing target and the time difference between this real time;

    The quantity of the remainder of the above-mentioned secondary sources that calculating can transmit during this time difference;

    WithThis remainder quantity of above-mentioned secondary sources is added to this rapid data that during this predetermined timing target, transmits.
