DTSF666说明书 (1)

1.读卡器或售电机操作说明书（RW666型）正泰售电机管理系统软件（RW666型IC读卡器）一、安装好售电系统后（不要安装在C盘），装好读卡器的电源线、数据线连接上后，系统提示发现新硬件，安装好驱动后。

将电表包装盒内的“购电卡”插入读卡器（箭头指示的方向朝上，推进出用力压到位，直到不能弹出后松手）。

拔卡方法：再压-松手弹出。

二、适用于：正泰生产DDSY666、DTSY666电能表产品。

三、进入软件：系统默认管理员123，密码123，进入.四、修改电价：用户管理→电价维护→删除不需要的电价类型→双击需要修改的电价单价值→改成小区售电电价→保存五、修改密码（此步骤由用户决定是否修改）用户管理→修改密码→原密码123→输入两遍新密码→确定六、建档用户管理→档案管理→增加→用户编号、电表编号任意编制数字（用户号可以与电表号相同但不能与档案中已存在的其他用户相同，即一户一号），输入用户名称（如张三，可不写）、输入用户地址（如1号楼1单元101），证件代码、用户电话可输可不输，电表类型选择单相电能表（如果是三相表就选择三相表，当选择三相表后弹出CT值，一般为1，加互感器的除外，后面有说明。

）→点击保存→出现提示是否制作初始化卡→点击“是”→将新卡插入读卡器→点初始化卡操作中的“写卡”输入一级报警：10，二级报警：5，负荷阀值：40 （电表的最大工作电流，家用电器实际工作电流≥设置数值，电表自动跳闸断电，例如：5/20A电表，最大工作电流20A，10/40A电表，最大工作电流40A，如果用户负载或电器功率大，最大工作电流+10A）→选择电价类型→选中“度数或金额”→输入第一次售电度数或者金额→点击“确认写卡”→出现初始化卡制作成功→拨出读卡器中的卡→在卡的背面标注用户名“张三”→发卡给张三。

这里需要注意一点：做好的初始化卡第一次插入哪块电表后，以后该表只认这张卡，而这张卡也只能给这块表充电，所以第一次卡一定插对。

被计量的电能电压信号经过电阻分压取样，通过ADE7752芯片内部的差放电路将信号放大，再经过A/D转换成与其成比例的数字信号，进入数字乘法器的另一个输入端与电流通道的信号进行乘法运算，完成被计量电能的瞬时功率测量。

每相输出瞬时功率通过数字低通滤波器，进行积分处理，然后进行绝对值累加后进入“数字/频率”转换器，经过分频电路输出的脉冲经过隔离后送入费率单元进行处理，记录总电量及费率电量。

3.2 费率单元工作原理电能计量单元输出的高频脉冲通过两个光电耦合器，一路作为无源脉冲输出用于出厂检验和用户对电能表进行校验；另一路送到CPU芯片进行数据处理。
