Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a smart socket capable of storing the current relay on-off state and the user’s last setting for the defect that the above-mentioned smart socket in the prior art cannot ensure that the relay on-off state is the same as the user’s last setting when the MCU is softly restarted. The broken state (that is, the state set by the user last time) and maintain the original state after a soft restart

Embodiment Construction

[0020] Such as figure 2 As shown, the smart socket of the present invention includes: a microprocessor 10 , a state storage circuit 20 , a switching control circuit 30 , a switching device 40 , and an RF communication module 11 .

[0021] Wherein, the switch device 40 is connected between the live wire input end and the live wire output end of the smart socket. The switching control circuit 30 is connected with the switching device 40 and is used for switching the on / off state of the switching device 40 according to the control signal.

[0022] The RF communication module 11 is connected with the microprocessor 10, and is used for receiving wireless control instructions from the user's smart terminal (such as a smart phone, a tablet computer, a personal PDA, etc., which can install a control application program). Alternatively, the RF communication module 11 may also be built into the microprocessor 10 .

[0023] The state storage circuit 20 is arranged between the switch s...

Abstract

The invention relates to an intelligent socket which comprises the components of a switch device which is connected between a live-wire input end and a live-wire output end of the intelligent socket; a switching control circuit which is used for switching on / off state of the switch device; an RF communication module which is used for receiving a wireless control instruction from a user terminal; a microprocessor which is used for supplying a control signal to the switching control circuit according to the wireless control instruction; and a state storage circuit which is arranged between the switching control circuit and the output end of the microcontroller and is used for storing the current setting and generating a corresponding output signal according to the stored setting in soft restarting of the microprocessor, thereby keeping the original state of the switch device. Through application of the intelligent socket, more stable function of the intelligent socket can be realized; and abnormal switching of a relay is prevented even on condition that the microprocessor is restarted because of some reasons in a non-manual manner, thereby ensuring normal use of the user.

Description

technical field [0001] The present invention relates to a power socket, and more specifically, to an intelligent socket. Background technique [0002] One of the most basic functions of smart socket products is to be able to wirelessly control the on and off of the AC power of the socket. figure 1 Shown is a schematic diagram of an existing smart socket. Among them, the RF communication module receives the control information of the terminal, and the MCU outputs the control information through the MCUIO port to control the power supply of the magnetic coil of the relay, thereby controlling the pull-in and disconnection of the relay contacts. [0003] This kind of circuit design has disadvantages, that is, when some kind of accident occurs, such as when the system program runs abnormally, or the system power supply fluctuates abnormally, the system will restart without power interruption (called soft restart), causing the MCU to malfunction. Soft restart behavior, this kind...
