1. a temperature and pressure compensation scaling method for pressure unit, in temperature and pressure compensation calibration system, is characterized in that:

  • Described temperature and pressure compensation calibration system comprises;

    industrial computer and at least two control panels, in described at least two control panels, each connects one respectively and treats the pressure unit that temperature and pressure compensation is demarcated, and described industrial computer is all connected with communication bus by signal synchronous clock control line with each in described at least two control panels;

    Described method comprises step;

    Demarcate under temperature and the first nominal pressure in first;

    The level of described synchronous clock control line is set to second electrical level by the first level by described industrial computer, and transmits the Radio Broadcasting Agreements frame of pressure calibration instruction to described communication bus;

    When the level that each in described at least two control panels monitors described synchronous clock control line is described second electrical level by described first level transitions, received the Radio Broadcasting Agreements frame of described pressure calibration instruction by described communication bus;

    AndEach in described at least two control panels is after the Radio Broadcasting Agreements frame successfully receiving described pressure calibration instruction, and the Radio Broadcasting Agreements frame according to described pressure calibration instruction carries out temperature and pressure compensation demarcation.
