    • A data communication control system includes first and second control units each having a microcomputer, the second control unit carrying out a first interrupt processing which starts in accordance with a first timing signal having a first period, and a second interrupt processing which starts in accordance with a second timing signal having a second period, the second interrupt processing being for the second control unit to receive data transferred from the first control unit. The second timing signal is generated in the first control unit in such a manner that adjacent ones of the second timing signal have values of the second period different from each other. Therefore, even if the first interrupt processing and the second interrupt processing conincide with each other the coincidence is not continued whereby transfer of data can be reliably carried out.
    • 数据通信控制系统包括第一和第二控制单元,每个控制单元均具有微计算机,第二控制单元执行根据具有第一周期的第一定时信号开始的第一中断处理,以及根据 具有第二周期的第二定时信号,所述第二中断处理用于所述第二控制单元接收从所述第一控制单元传送的数据。 在第一控制单元中产生第二定时信号,使得第二定时信号的相邻值具有彼此不同的第二周期的值。 因此,即使第一中断处理和第二中断处理相互一致,不能继续一致,从而可以可靠地执行数据的传送。

    • A set rotation angle width related to a rotary machine, of which the rotation speed varies cyclically, is converted to a time width required for the rotary machine to rotate by the set rotation angle width from a given rotation angle position. The converted time width is corrected by a correcting coefficient so that the time width is not affected by the rotation variation of the rotary machine. The correcting coefficient is decided based on the rotation angle position and the rotation speed variation of the rotary machine related to the set rotation angle width from the rotation angle position, and by the correcting coefficient, correction is done so that an actual rotation angle width corresponding to the converted time width becomes the set rotation angle width.
    • 与旋转机器周期性变化的旋转机器相关的旋转角度设定转换为旋转机器从给定旋转角度位置旋转设​​定旋转角度宽度所需的时间宽度。 通过校正系数校正转换的时间宽度,使得时间宽度不受旋转机器的旋转变化的影响。 校正系数是根据与旋转角度位置相对于设定的旋转角度宽度的旋转机械的旋转角度位置和旋转速度变化来确定的,并且通过校正系数,进行校正,使得实际旋转角度宽度对应 转换后的时间宽度成为设定的旋转角度宽度。
