[0019] like Figure 1 This is a structural diagram of the utility model, an environmentally friendly and energy-saving smart socket, characterized in that it includes a smart socket main node 1 and several groups of smart socket sub-nodes 2, the smart socket main node 1 includes a main controller module, a main infrared module, a communication module and a main power supply module, the smart socket sub-node 2 includes a branch infrared module, a branch controller module, a node relay, a camera module, a voice module, a power metering module and a branch power supply module, the main power supply module supplies power to the main control module, the main control module communicates bidirectionally with the cloud platform through the communication module, and communicates bidirectionally with the branch infrared module through the main infrared module; the branch controller module is powered by the branch power supply module, receives information signals from the camera module, voice module, and power metering module, issues instructions to the node relay, and communicates bidirectionally with the branch controller module through the branch infrared module.

[0020] Specifically, the main infrared module and the branch infrared module include infrared transmitting and receiving circuits, which are implemented using transistors and infrared transmitting and receiving tube pairs. Transistor Q2 generates a fundamental signal and provides a 38kHz square wave fundamental signal to its gate. Transistor Q1 is a sending control transistor. It is connected to the serial port sending pin, and the message to be sent can be loaded on the fundamental signal. The circuit is composed of a transmitting tube and a receiving tube, and the serial port communication is asynchronous communication, so the receiving and sending are independent of each other. When sending, it is necessary to pay attention to turning off the receiving interrupt, or use a barrier to isolate the transmitting tube and the receiving tube to avoid self-reception at the sending end; the node relay is controlled by the main controller module and the branch controller module to be attracted and closed. The system uses a linkage relay. One relay links two signals. The electric shock threshold is AC 10A. In order to prevent the instantaneous surge of attraction from damaging the microcontroller, a freewheeling diode is installed to protect the circuit.

[0021] According to another embodiment of the present utility model, it further includes that the several groups of smart socket sub-nodes 2 are arranged inside the socket shell 3, the camera module includes a camera 4, the voice module includes a voice acquisition module 5 and a voice recognition module, the socket shell 3 is installed with a camera 4 and a relay is provided inside the voice acquisition module 5, the camera 4 is electrically connected to the branch controller module, and the voice acquisition module 5 is electrically connected to the branch controller module through the voice recognition module.

[0022] Specifically, the camera module is used to obtain human gestures. The user makes the corresponding gestures in front of the camera. The camera captures the user's gestures in real time and stores the captured gesture images in the branch controller for analysis and comparison, thereby achieving gesture control; the voice acquisition module 5 is responsible for obtaining sound input, and the specified voice commands issued by the designated user are transmitted to the voice recognition module, and the sensor for collecting sound is responsible for converting vibrations into current signals readable by the branch controller. The conversion process is displayed in the form of a sound waveform, which includes the pitch, timbre and volume information of the speech. After receiving the sound waveform, the branch controller performs voiceprint recognition. In most cases, the sound waveform includes a lot of noise in addition to the human voice. The first step of recognition is to separate the human voice from it, and then compare and confirm to complete the sound wave recognition.

[0023] According to another embodiment of the present invention, the voice acquisition module 5 uses the chip PCM1864; the voice recognition module uses the chip LD3320.

[0024] According to another embodiment of the present invention, the main power supply module and the branch power supply module further include an AC-DC power conversion module, including linear power supply chips AMS1117 and LM1085, to power the main controller module, the communication module and the branch controller module, wherein the AC-DC power conversion module converts 220V AC power into 5V DC power, and then uses the linear power supply chips AMS1117 and LM1085 to reduce the 5V voltage to 3.3V to power the main controller module, the branch controller module and the communication module.

[0025] According to another embodiment of the present invention, the main controller module and the branch controller module use the chip STM32F103RCT6, and the communication module uses the chip EC200S.

[0026] Specifically, the chip EC200S is an LTE Cat1 wireless communication module launched by Quectel Communications. It supports a maximum downlink rate of 10 Mb / s and a maximum uplink rate of 5 Mb / s, and has an extremely high cost-effectiveness. Since the 4G module requires a starting current of about 1 A to start the antenna when in use, it will cause an instantaneous impact response to the embedded system, easily causing the linear power supply voltage to drop, resulting in the restart of the microcontroller and the 4G module. Therefore, when in use, the 4G module needs to be equipped with a 47μF tantalum capacitor for energy storage to provide sufficient current support for the chip startup moment to ensure that the embedded system can work stably and enhance its anti-interference ability. The signal pin of the SIM module is protected by a PVS diode to prevent breakdown, and a filter capacitor is selected to provide signal protection.

[0027] According to another embodiment of the present invention, it further includes that the cloud platform and the mobile phone APP communicate with each other in a two-way manner.

[0028] Specifically, the 4G module is controlled to open the MQTT protocol by sending AT commands to the serial port of the 4G module through the serial port, and the device account, password, and IP address of the cloud platform are entered. After the connection is successful, the command module is set to the publishing mode. After returning success, an attempt is made to push a message. If the push is successful, it means that the cloud platform has been successfully connected. Since the smart socket main node 1 uses the 4G module to connect to the network and also needs to monitor whether the smart socket sub-node 2 has issued a request instruction, it is necessary to continuously scan the serial port to respond in time and process the message of the smart socket sub-node 2. Among them, the smart socket main node 1 uses the FreeRTOS operating system, which can realize multi-threaded operation. The main program is divided into a heartbeat packet thread, an infrared control thread, and an exception handling thread. The heartbeat packet thread has the same priority as the infrared control thread, and the exception handling thread has the highest level, which can prevent interruptions during the message sending process and cause message sending failures. When using the mobile phone software, the first login requires binding the MAC address of the smart socket master node 1 and establishing a communication line between the mobile phone and the smart socket master node 1. After the communication line between the mobile phone and the smart socket master node 1 is established, the smart socket master node 1 will send all its smart socket child nodes 2 to the mobile phone and display them in a list. Users can name or control them to achieve remote single control or scene control and other joint control effects.

[0029] The specific operation process is that when the user adds the newly purchased smart socket to the home node, he only needs to plug the smart socket into the socket to power it. At this time, the smart socket sends an infrared signal to request the address code from the smart socket main node 1. After receiving the request message, the smart socket main node 1 will assign a unique address code to the smart socket under this network to achieve separate control between different smart sockets. Then the user can use voiceprint and gesture recognition to conveniently turn on the relay of the smart socket sub-node 2. The user can also confirm the working status of the smart socket sub-node 2 through the power metering module and the data information of the smart socket sub-node 2, and can remotely turn it off and on through the mobile phone APP.

[0030] The above description is only illustrative and not restrictive of the present invention. Those skilled in the art will understand that many modifications, changes or equivalents may be made without departing from the spirit and scope defined by the appended claims, but all of them will fall within the scope of protection of the present invention.
