The invention provides a load acquisition device of a charging pile and a household power supply system. The power supply end of the power supply circuit is connected with the amplification circuit and the analog-to-digital conversion device. The detection end of the detection device is arranged on a home-entry line and detects the current home-entry current. The output end of the detection device is connected with the input end of the analog-to-digital conversion device through the amplification circuit, and the output end of the analog-to-digital conversion device is in communication connection with the charging pile through the communication device. As the load acquisition device comprises the analog-to-digital conversion equipment, analog signals acquired by the detection equipment can be converted into digital signals by utilizing the analog-to-digital conversion equipment, and the load acquisition device can transmit the current home-entry current to the charging pile in a digital signal mode; the digital signals are not easy to interfere, so that the charging pile can be installed at a position far away from the detection equipment, the detection equipment can be a current transformer, and the load acquisition device can enable the charging pile to be installed at a position farther away from the current transformer.
本申请提供一种充电桩的负荷采集装置和户用供电系统。供电电路的供电端分别与放大电路、模数转换设备相连;检测设备的检测端设置于入户线路上,检测当前入户电流;检测设备的输出端通过放大电路与模数转换设备的输入端相连,模数转换设备的输出端通过通信设备与充电桩建立通信连接。由于该负荷采集装置中包括模数转换设备,所以可以利用模数转换设备将检测设备采集的模拟信号转换为数字信号,因此该负荷采集装置可以以数字信号的方式将当前入户电流传输给充电桩;又由于数字信号不容易受到干扰,所以充电桩可以安装在距离检测设备较远的位置,而检测设备可以为电流互感器,因此该负荷采集装置可以使充电桩安装在距离电流互感器更远的位置。
