After setting the parameters, the controller obtains the set parameters and time parameters, and sends the set parameters and time parameters to the display for display at the same time; S4.控制模块在获取时间参数后，将时间参数与设定的时间参数进行对比，看时间参数是否在设定的时间参数阈值内，若在，则进入S5；若否，则进入S8；S4. After obtaining the time parameter, the control module compares the time parameter with the set time parameter to see if the time parameter is within the set time parameter threshold, if so, enter S5; if not, enter S8; S5.控制模块发送信号至继电器模块，控制继电器进入闭合状态，插座通电；使得用电设备通电；S5. The control module sends a signal to the relay module to control the relay to enter the closed state, and the socket is energized; the electrical equipment is energized; S6.控制模块通过电流采集模块采集电流，并将采集的电流与设定的阈值进行比较；S6. The control module collects the current through the current collection module, and compares the collected current with the set threshold; S7.控制模块判断采集的电流值是否在设定的电流阈值内，若在，则继续采集电流，插座处于正常工作状态；若否，则进入S8；S7. The control module judges whether the collected current value is within the set current threshold, and if so, continues to collect current, and the socket is in normal working state; if not, then enters S8; S8.控制模块则发送信号至继电器模块，控制继电器处于断开的状态，使得插座处于断电状态；系统进入休眠状态，控制模块停止工作。S8. The control module sends a signal to the relay module, and the control relay is in a disconnected state, so that the socket is in a power-off state; the system enters a sleep state, and the control module stops working. 2.根据权利要求1所述的一种定时开关智能插座的控制方法，其特征在于：所述的时钟模块采用DS1302时钟芯片，所述的按键调节模块设置有用于设定开启或关闭时间的按键。2.
