随着“四化”和城市建设发展需要,为了加强科学管理,节约用水,我们研制一种五位液晶数字显示,Cmos中规模集成电路电子水表,见框图(工作原理如图1所示)。用电子电路代替了机械式水表全部齿轮传动机构和旋转角测定机构,减少了机械磨损、延长了使用寿命。调试简单、易于制造,适用于各种机械式水表的改装,并可根据不同要求放在旧式表壳内和进行远距离传送(图2为远传电子水表外形图),为便于统一规
With the needs of “four modernizations” and urban development, in order to strengthen scientific management and save water, we have developed a five-digit LCD digital display, Cmos medium-scale integrated circuit electronic water meter. See the block diagram (working principle shown in Figure 1). Instead of the mechanical water meter, all the gear transmission mechanisms and the rotation angle measuring mechanism are replaced by electronic circuits, which reduces mechanical wear and prolongs the service life. Easy to debug, easy to manufacture, suitable for all kinds of mechanical water meter conversion, and according to different requirements placed in the old case and carry long-distance transmission (Figure 2 for remote electronic water meter outline), in order to facilitate the unified regulation
