【無線液位傳輸器應(yīng)用案例】高位蓄水池水位無線遙控抽水泵方案
一、706X66G259方案介
本方案采用433MHz自主無線通信方式,沒有運行費用,實時通信,并借助公用GSM網(wǎng)絡(luò),通過短信實現(xiàn)遠程報警。
先將每個蓄水池分為2段,代表2個不同的水位高度,用浮球狀態(tài)來表示蓄水池當前水位高度。把液位開關(guān)信號引入無線水位發(fā)射裝置,如果水池附近沒有動力電源,可以采用達泰一體化太陽能電源供電。
706X66G259山下泵房控制室無線接收裝置收到山上發(fā)來的上下水位信號后,通過控制電路輸出開泵信號或者停泵信號。同時短信報警器給值班人員手機發(fā)送通知短信,實時報告當前的水位狀態(tài)和水泵工作狀況。
