Alternatively, the energy storage device may also be a lithium battery or other rechargeable energy storage element.
The utility model discloses an intelligent switch can directly replace original switch, can work under the single live wire condition. One or more live wires can be output, and the on-off of each output can be controlled (in fig. 2, one input and three outputs are provided).
The electricity-taking device with the single live wire comprises the electricity-taking circuit with the conventional single live wire in the field and the change and the modification of the electricity-taking circuit, which can meet the working requirements of the utility model. A feasible single live wire power taking circuit comprises: the voltage control circuit, the rectification filter circuit and the power supply circuit; the voltage control circuit comprises a voltage feedback circuit and a current control circuit; the rectification filter circuit comprises a rectification filter connected to the live wire inlet end; the voltage control circuit rectifies and filters through the rectifying and filtering circuit and supplies power to the power supply circuit. The power supply circuit charges the energy storage device and/or is used to maintain standby or low power operation of the smart switch.

For example, the projector connected with the intelligent switch is turned on through the intelligent switch, and when the working current of the projector is detected, the control unit sends information through the wireless communication module to control other switches to automatically turn on the curtain.
The intelligent switch is connected with and/or controls loads including but not limited to electric lamps, electric curtains, air conditioners, refrigerators, washing machines, televisions, set-top boxes and the like.
In addition, the control unit may set a sleep time during which only microampere-level current is consumed, while in standby. It should be noted that, in order to respond to the request in time, the wireless communication module does not sleep, but keeps working all the time, and when the wireless communication module receives data, the wireless communication module wakes up the control unit to work. Therefore, the wireless communication module can receive data in real time and wake up the control unit at once, but under the condition, the wireless module needs to continuously consume power, a single live wire is used for power taking and always works, and leakage current exists all the time. Because the wireless communication module (such as a Batell module) with low power consumption is selected, the leakage current in the standby process is very small, thereby effectively avoiding the phenomena of potential safety hazard and bad load flicker.
Due to the fact that the key timer is added, the control of the key switch is richer and more diversified, different control functions can be achieved only through operation of the same key switch, the intelligent control device is simplified, and user experience is improved.
The above embodiments are only used for illustrating the present invention, and not for limiting the present invention, and those skilled in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention, so that all equivalent technical solutions also belong to the scope of the present invention, and the protection scope of the present invention should be defined by the claims.
