中小城市、乡镇的厂矿或企事业单位,往往自设水塔。而水源却在数百米甚至上千米以外的河、湖或地下,且水泵都是就近设在水边的机房中。因为水泵容量的设置总是大于用水量,所以马达为间歇工作状态。马达开关一般由人工控制。这样,某些单位得专设两三个值班人员,不但人力浪费,且很不方便。笔者接受外单位委托,设计了一套无线电遥控装置,它与架设数百米的输电线进行有线控制相比,成本要低得多,且逻辑原理简单完善、性能可靠,可推广到其他类似功能的系统中去。在此介绍其基本构成,并着重介绍它的逻辑部分,以供各有关人员参考。 Small and medium-sized cities, towns and villages factories and mines or enterprises and institutions, often own water tower. The water is in the hundreds of meters or even kilometers away from the river, lake or underground, and the pumps are located near the water in the engine room. Because the pump capacity setting is always greater than the water, so the motor is intermittent working condition. Motor switches are normally controlled manually. In this way, some units have to set up two or three on-duty staff, which is not only wasteful and inconvenient. The author commissioned by the external units, designed a set of radio remote control device, which set up hundreds of meters of transmission lines for wired control, the cost is much lower, and the logic is simple and reliable, reliable performance, can be extended to other similar functions Go in the system Introduce its basic structure here, and highlight its logical part, for reference of all relevant personnel.
