发表在本刊79年第二期上的《计量桶逻辑控制及计数仪》一文,其中逻辑控制部分可进一步简化。这样不仅可以减少用料及劳务消耗,而且由于使用的元件较少,和元件结构较简单,从可靠性理论得知,这样就可提高系统的可靠性。而这也正是自动控制装置的一项重要指标。简化后可减少两个R—S触发器(见图1b)。图中未绘部分,则不作变更。由于A、B、C三态与D、E、F三态之间,有效输入信号及输出均没有重叠区域,故可只用一个R—S触发器区分,前三态为Q=1状
Published in the 79 issue of the second issue of “measuring barrel logic control and counter,” a text, of which the logic control part can be further simplified. This not only can reduce the consumption of materials and labor, but also because of the use of fewer components, and simple structure of the components, from the reliability theory that this will improve the reliability of the system. And this is exactly an important indicator of automatic control devices. Simplify to reduce two R-S flip-flops (see Figure 1b). The figure is not painted part, then no change. As the A, B, C tri-state and D, E, F between the three states, the effective input signal and the output have no overlapping area, it can only use a R-S flip-flop to distinguish the first three states Q = 1
