Description

Technical Field

[0001] The present invention relates to the technical field of smart power strips, and in particular to a smart power strip and a control method thereof. Background Art

[0002] A socket strip is a multi-socket with wires, also known as a power strip or a power strip. Its scientific name is a wire extension assembly or an extension cord socket. A socket strip refers to a multi-socket with power cords and plugs that can be moved. More than one power plug can be connected through a socket strip, which saves space and wires.

[0003] As people's demand for power strips increases, smart power strips have gradually appeared on the market. Currently, the smart power strips known to the public are those designed specifically for smart devices and equipped with USB ports that can directly charge smart devices. Compared with traditional national standard five-hole power strips, smart power strips have made more improvements in appearance and performance. Most smart power strips integrate traditional national standard five-hole sockets with USB ports to improve space utilization and work efficiency.

[0004] In order to further improve the working efficiency of socket strips, in order to further improve the working efficiency of socket strips, such as collective control of plant lights, fans, etc., people use a smart socket strip composed of multiple socket strips for connection and control. However, the existing smart socket strips have the following problems. Although the existing smart socket strips can be controlled in series, their series control can only realize synchronous power off or power supply actions. When it is necessary to control the electrical appliances connected to a single socket strip, it is necessary to manually control the single socket strip one by one, and it is impossible to control a single socket strip and then perform linkage control on the socket strips connected behind. The control method is single, which affects the efficiency of debugging and control; and the transmission power of a single plug panel is limited, which affects the scope of use of the socket strip.
