    阶梯值和阶梯区间阶梯电价方案的一种设置参数，阶梯值为D单位为kWh，阶梯区间是一个用电量的范围，单位为kWh。当阶梯值的数量为N时，可以将用电量范围划分为N+1个阶梯区间。2.阶梯电价管理方案阶梯电价管理方案包含确定阶梯值和对应的阶梯电价。例1：某阶梯电价方案确定3个阶梯值为D1、D2、和D3(单位为：kWh)。按照3个阶梯值划分的4个阶梯区间为W0、W1、W2、W3和确定对应的4个阶梯电价J0、J1、J2、J3，各阶梯区间的范围分别为：0≤W0≤D1、D1D3;阶梯电价单位为元，有两种表示方法：一种是直接的阶梯区间用电量的价格J0、J1、J2、J3，另一种是用阶梯电价与常规电价的差价表示方式：J'0、J'1、J'2和J'3，其中：J'0=0、J'1=J0-J1、J'2=J1-J2、J'3=J2-J3。阶梯电价与常规电价的差价表示方式用于阶梯费率电价管理比较方便。阶梯电价与常规电价的差价可以是正数、0或负数。1.功能用户持IC卡到供电部门交款购电，供电部门用售电管理机将购电量写入IC卡中，用户持IC卡在感应区刷非接触式IC卡(简称刷卡，下同)，即可合闸供电，供电后将卡拿走。当表内剩余电量等于报警电量时，拉闸断电报警(或蜂鸣器报警)，此时用户在感应区刷卡即可恢复正常，此时用户在感应区刷卡即可恢复供电。周边支持方式-将蜂鸣片外径边缘固定于共振腔内，一般采无回授式蜂鸣片。虹口区订做AD16系列蜂鸣器推荐厂家

    大家好，教大家制作一个简单的水满提示装置。只需三个简单的元器件就能制作一个水满提示装置，再也不用担心水溢出来了！我们知道厨房安装有净水器，净水器会产生废水，想利用起来，放一个小桶来装水，但又怕平时没有注意水满出来，我们就想设计一款电路，当水到一定的界限时由蜂鸣器或者LED灯来提醒。于是有了水满提示装置。只需三个元器件，8050NPN一个，发光二极管一个，蜂鸣器一个。焊接好并成为三极管开关电路。接下来就是泡沫装置，这个所要的材料有：一根铁条绕成的U形，泡沫、一片金属片、两个绕成S型的两根导线，一块木块。整个装置的原理是：当水位上升泡沫开关闭合时，三极管的B极接高电平，三极管导通，LED灯亮，蜂鸣器响起来，当断开时，三极管的B极断电，三极管截止。LED灯灭，蜂鸣器不响。起到提示作用。
