Description

Technical Field

[0001] This application relates to the field of socket technology, and more particularly to an energy-saving socket. Background Technology

[0002] With societal development, electrical equipment is increasingly used in daily life. These devices are typically turned on and off manually, remotely, or wirelessly. Electronic devices generally operate in two states: full-load operation and standby. Switching between these two modes means that electrical devices spend most of their time in standby mode. In this state, the device's power circuit is active, ensuring basic functions operate at minimum power consumption, and can be turned on upon receiving a valid signal. However, prolonged operation of the power circuit reduces the device's lifespan and poses safety risks. While some electrical outlets have main power switches, this is inconvenient in practice due to frequent operation or the need for initialization after powering on; prolonged standby becomes a habit, and safety concerns are easily overlooked.

[0124] Furthermore, the memory chip IC2 is connected to one end of the resistor group, the other end of the resistor group is connected to the microcontroller chip IC1, the microcontroller chip IC1 is also connected to the positive terminal of the light-emitting diode, and the negative terminal of the light-emitting diode is grounded.

[0125] Preferably, the light-emitting diode can be a red LED model, and it can be set to light up red when a 5V signal is connected to the GPIO interface of the microcontroller chip, but it is not limited to this.

[0126] As attached Figure 2As shown in this application, the circuit principle of an energy-saving socket circuit is as follows:

[0127] Upon power-up initialization, the socket undergoes a process where the microcontroller IC1, communication chip U3, and other chips are reset, completing the initialization. The adapter of the electrical device connects to the socket interface and operates normally for a period of time, which can be measured in days. The microcontroller reads control parameters from the memory chip IC2 via the serial port, including timer switch settings and energy-saving mode settings. Simultaneously, the microcontroller can send control signals to disconnect the relay switch K, thus de-energizing the socket output.

[0128] During normal operation, the signal detection circuit collects voltage and current signals in real time and transmits them to the memory chip IC2. The microcontroller determines the load status based on the real-time power parameters recorded by the memory chip. The load status can be divided into full-load working state and low-power standby state. The working time and the longest standby time of the electrical equipment are confirmed by continuously monitoring the current and voltage on the electrical equipment socket. The longest standby time that repeats at the same time in different cycles is determined as the disconnection control point of the socket.

[0129] For example, after a preset cycle of testing (24 hours), the disconnection control points of the electrical equipment are confirmed as: point A is disconnected and point B is turned on. When the time reaches point A, if the electrical equipment is in working condition, no action is taken and the testing continues. If the electrical equipment is in standby condition, the power supply to the electrical equipment is disconnected. If a low-power condition is detected at night, the equipment enters sleep mode.

[0130] Furthermore, after disconnecting the power supply to the electrical equipment, the user can manually operate the power-on button to turn the power supply back on. If the user does not manually turn it on, when the time reaches point B, that is, when the preset power-on time is reached, the microcontroller chip closes the sleep mode, sends a control signal, drives the relay to engage, and the socket output terminal is powered on, automatically turning on the electrical equipment.

[0131] Additionally, the communication chip U3 connects to a WiFi network, awaiting remote control commands from an app or cloud server. If a power on / off command is received from the app, it executes the corresponding action to control the relay switch. During operation, the circuit continuously monitors voltage and current parameters and control commands, achieving intelligent autonomous control. Furthermore, in case of a fault or abnormality, it quickly disconnects the relay to protect the circuit.

[0132] In summary, in this energy-saving socket, the microcontroller IC1 provides overall control of the socket, receiving control commands from the communication module and panel controls, driving relay switches according to control logic, and communicating with the memory chip to complete data storage. A light-emitting diode (LED) displays the real-time operating status. Furthermore, a resistor group is used for voltage division of the microcontroller chip's operating voltage. The various circuit modules designed in this application, together with the chip, realize intelligent control and human-machine interaction functions for the socket. It can be controlled remotely or locally via panel controls, improving the system's flexibility.
