Description

Smart socket device and indoor environment control system including the thereof

This invention relates to the technical field of wall outlets, particularly a smart outlet device that can be wirelessly controlled, providing smart power control, monitoring functions, integrated environmental sensing, USB charging, and collaborative control capabilities with other smart devices.

Figures 1A and 1B are first and second perspective views of a conventional socket. As shown in Figures 1A and 1B, the conventional socket 1a mainly includes a panel 10a and an electrical assembly 11a. The panel 10a has at least two openings 101a, and the electrical assembly 11a includes a socket 111a and an electrical connector 112a. More specifically, the socket 111a includes two sets of sockets 111Ha, and each set of sockets 111Ha includes a first socket, a second socket, and a third socket. Correspondingly, the electrical connector 112a includes two sets of contact terminals, wherein each set of terminals includes a first contact terminal, a second contact terminal, and a third contact terminal respectively located in the first socket, the second socket, and the third socket. Furthermore, the electrical connector 112a includes two terminal blocks, each of which includes a first terminal block 112La and a second terminal block 112Na, which are respectively electrically connected to the first contact terminal and the second contact terminal. The electrical connector 112a also includes a third terminal block 112Ga, which is electrically connected to the third contact terminal.

The socket 1a is typically embedded in a recessed groove in the wall, such that the electrical connection component 11a is housed in the recessed groove, and the live wire and neutral wire reserved in the recessed groove are electrically connected to the first terminal 112La and the second terminal 112Na, respectively.

Figure 2 is a perspective view of a household appliance and an existing socket. To use the appliance 2a, its power plug 21a must first be inserted into a socket group 111Ha of the socket 1a. Specifically, the power plug 21a includes a first terminal, a second terminal, and a third terminal. The first terminal contacts the first contact terminal in the first socket, the second terminal contacts the second contact terminal in the second socket, and the third terminal contacts the third contact terminal in the third socket. Then, pressing a power button on the appliance 2a will turn it on.

It should be understood that even if the user presses the power button to turn off the appliance 2a, it will remain in standby mode and consume standby power if the power plug 21a is not unplugged from the socket 1a. In other words, when there is no need to use the appliance 2a, the user must move to the socket 1a and unplug the power plug 21a to completely stop the appliance 2a from consuming power. Obviously, this causes a lot of inconvenience to the user.

With the development and application of wireless network technology, it is necessary to consider improving the design of the existing socket 1a so that users can remotely operate it using a smartphone, tablet, or remote control, thereby completely cutting off the mains power supply to the household appliance 2a when it is not needed. Furthermore, during the design improvement, more functions such as indoor environment adjustment can be integrated into the improved remotely operable socket, making it a new type of smart socket device. In view of this, the inventor of this invention has devoted considerable effort to research and creation, and has finally developed a wirelessly controllable smart socket device.

Currently, smart sockets from brands such as TP-Link, Xiaomi, Meross, and Foxconn/WNC generally offer basic functions like remote control, timed scheduling, and voice assistant integration. However, most smart socket products still focus on single-device control, lacking inter-device connectivity for multiple scenarios and offering limited protocol integration, often requiring external network gateways for cross-platform operation. Furthermore, while some products have power monitoring functions, they often lack automatic power-off or anomaly protection mechanisms, failing to meet the proactive energy management needs of complex home or commercial environments. Therefore, smart sockets must address three major issues: insufficient communication between protocols, inadequate scenario control, and energy security.

The main purpose of this invention is to provide a smart socket device that has the function of wireless control and is configured to control at least one light fixture, at least one electric curtain, at least one electrically controlled color-changing window, and/or at least one air conditioning unit in a wired or wireless manner, thereby realizing indoor environmental regulation.

Furthermore, at least one electric curtain 5 is installed on either the first pair of exterior walls or the second pair of exterior walls of the indoor environment to cover the at least one window. In practical application, as shown in Figure 3, the smart socket device 1 of the present invention is installed on either the first pair of exterior walls or the second pair of exterior walls, or on an indoor wall of the indoor environment. To explain in more detail, the smart socket device 1 of this invention is wired or wirelessly coupled to at least one light fixture 2, at least one air conditioning unit 3, at least one electrically controlled color-changing window 4, and at least one electric curtain 5, and wirelessly connected to a client electronic device 6 and/or a control electronic device 7 located in the indoor environment (or within the wireless network coverage area), thereby forming an indoor environment control system (IAS) with the at least one light fixture 2, at least one air conditioning unit 3, at least one electrically controlled color-changing window 4, at least one electric curtain 5, client electronic device 6 and/or control electronic device 7.

Figures 4A and 4B are first and second exploded perspective views of the smart socket device of this invention. As shown in Figures 3, 4A, and 4B, the smart socket device 1 of this invention includes: a housing 10, at least three conductive elements 13, a first circuit component 11 (i.e., a power module), a second circuit component 12 (i.e., a control and processing module), N sockets 12S, and a panel 1F, where N is a positive integer. Normally, the smart socket device 1 is installed in a recess in the first pair of exterior walls, the second pair of exterior walls, or the interior wall, and the recess typically contains at least one live wire and one neutral wire. In some embodiments, the recess typically contains one live wire, one neutral wire, and one ground wire simultaneously. Correspondingly, the receiving box 10 has a first top opening 101, and at least three holes 102 are provided on one side (e.g., the bottom side). On the other hand, the at least three conductive members 13 are disposed inside the receiving box 10, and are exposed from the receiving box 10 through the at least three holes 102. In practical applications, the conductive members 13 can be wires or conductive terminals, and the at least three conductive members 13 are used to electrically connect a live wire, a neutral wire, and a ground wire.

According to this invention, the first circuit component 11 (i.e., the power module) is disposed within the housing 10, and mainly includes a first circuit board 110, a power conversion module 111, and N power switching units 112. The power conversion module 111 is electrically connected to the live wire and the neutral wire via two conductive elements 13 to receive AC power, and is configured to perform AC-DC conversion on the AC power. Furthermore, the N power switching units 112 are electrically connected to the power conversion module 111 and the live wire.

Furthermore, Figure 5 is a circuit block diagram of the power conversion module shown in Figure 4A. In one embodiment, the power conversion module 111 includes an AC-DC conversion circuit 1C1 and a DC-DC conversion circuit 1C2. The AC-DC conversion circuit 1C1 includes an input protection unit 1C11, an input rectifier unit 1C12, a first input filter unit 1C13, a first buck converter chip 1C14, a first output rectifier unit 1C15, a first output filter unit 1C16, a first voltage divider resistor unit 1C17, and a first current sensing resistor 1C18. Specifically, the input protection unit 1C11 is electrically connected to the live wire and the neutral wire to receive the mains power, and consists of a high-voltage fuse and a high-voltage diode. On the other hand, the input rectifier unit 1C12 is electrically connected to the input protection unit 1C11 to receive the mains power and rectifies the mains power into a first power signal. Furthermore, the rectifier unit 1C12 consists of two rectifier diodes connected in series. More specifically, the first input filter unit 1C13 is electrically connected to the rectifier unit 1C12 and performs a first filtering process on the first power signal. As shown in Figure 5, the first input filter unit 1C13 includes two input capacitors connected in parallel and an input inductor connected between the two input capacitors.

As shown in Figures 4A and 5, the first buck chip 1C14 is electrically connected to the first input filter unit 1C13 and has a first voltage output terminal, a first ground terminal coupled to a circuit ground terminal (or system ground terminal), a first voltage feedback terminal, and a first current sensing terminal. It is used to perform a first voltage reduction processing on the first power signal, thereby outputting a second power signal. For example, the voltage of the first power signal is 110V or 220V, and the first buck chip 1C14 outputs the second power signal with a voltage of 12V. To explain in more detail, the first output rectifier unit 1C15 is coupled between the first ground terminal and the first voltage output terminal, and is used to perform rectification processing on the second power signal. In a practical application, the first output rectifier unit 1C15 can be composed of two reverse-connected diodes and a capacitor, wherein the capacitor and the two N-terminals (or cathodes) of the diodes are connected to the same node. Furthermore, the first output filter unit 1C16 is coupled between the circuit ground terminal and the first output rectifier unit 1C15, and performs a second filtering processing on the second power signal. In a practical application, the first output filter unit 1C16 can be composed of an output inductor and an output capacitor, and the output capacitor can be connected in parallel with an output resistor 1C1R.

It is worth noting that the first buck chip 1C14 has a voltage/current feedback control function to stabilize the voltage output of the second power signal. Therefore, as shown in Figure 5, the first voltage divider resistor unit 1C17 is coupled between the first voltage feedback terminal, the first ground terminal and the first voltage output terminal, and the first current sensing resistor 1C18 is coupled between the first current sensing terminal and the first ground terminal.

Furthermore, as shown in Figure 5, the DC-DC converter circuit 1C2 includes a second buck chip 1C21, a second output filter unit 1C22, and a second voltage divider unit 1C23. The second buck chip 1C21 has a voltage input terminal, a voltage output terminal, a feedback input terminal, and a ground terminal coupled to the circuit's ground terminal. Specifically, the voltage input terminal is electrically connected to the first output filter unit 1C16 to receive the second power signal, and the second buck chip 1C21 performs a second voltage reduction processing on the second power signal, thereby outputting a third power signal. For example, the voltage of the second power signal is 12V, and the output voltage of the third power signal of the second buck chip 1C21 is 3.3V.

To explain in more detail, the second output filter unit 1C22 is coupled between the voltage output terminal and the circuit ground terminal, and performs a third filtering process on the third power signal. Similarly, the second buck chip 1C21 has a voltage feedback control function to stabilize the voltage output of the third power signal, and therefore a second voltage divider unit 1C23 is provided coupled between the voltage output terminal and the ground terminal. To further explain, the second circuit component 12 includes a second circuit board 120, a microprocessor 121, a wireless signal processor 122, at least one temperature sensor 123, at least one ambient light sensor 124, N light-emitting button switches 125, at least one electrical connector 126, and a power monitoring chip 127. The microprocessor 121, the wireless signal processor 122, the at least one temperature sensor 123, the at least one ambient light sensor 124, and the N light-emitting button switches... The switch 125, the at least one electrical connector 126, and the power monitoring chip 127, and the second buck chip 1C21 provides the third power signal to the second circuit component 12 through the second output filter unit 1C22.

Furthermore, Figure 6 is a circuit block diagram of the power switching unit shown in Figure 4A. As shown in Figures 4A, 5, and 6, the power switching unit 112 includes a relay 1121 and a control chip 1122. The relay 1121 has an input terminal, an output terminal, a first signal terminal, and a second signal terminal. The input terminal is electrically connected to the live wire, and the output terminal is electrically connected to the first contact terminal. On the other hand, the control chip 1122 is electrically connected to the first output filter unit 1C16 of the AC-DC conversion circuit 1C1 of the power conversion module 111 to receive the second power signal (i.e., the 12V power signal), and is coupled to the first signal terminal and the second signal terminal of the relay 1121 and the microprocessor 121. With this configuration, the microprocessor 121 controls the relay 1121 to perform a first switching operation to couple the first contact terminal to the live wire, or controls the relay 1121 to perform a second switching operation to disconnect the electrical connection between the first contact terminal and the live wire.

It should be noted that the relay 1121 is also called an electric relay, and as shown in Figure 6, its simplest composition includes an (electromagnetic) coil and a switching contact. More specifically, the switching contact is further divided into normally open (NO) and normally closed (NC) contacts. Figure 6 is a circuit diagram of a relay 1121 with a normally open contact. In other words, in practical applications, the relay 1121 can also be designed with a normally closed contact.

Furthermore, Figure 7 is a block diagram of the second circuit component. According to this invention, the microprocessor 121 is coupled to the wireless signal processor 122, the at least one temperature sensor 123, the at least one ambient light sensor 124, the N light-emitting button switches 125, the at least one electrical connector 126, and the power monitoring chip 127. Furthermore, the panel 1F is connected to the housing 10 to close the first top opening 101, and has N first openings 1F1, at least one second opening 1F2, one third opening 1F3, and N pressable areas 1FP. Furthermore, as shown in Figures 4A and 4B, the N connectors 12S are exposed on the panel 1F through the N first openings 1F1, and the pressable area 1FP is adjacent to the first opening 1F1. On the other hand, the temperature sensor 123 is coupled to the power conversion module 111 and the microprocessor 121, and the ambient light sensor 124 is coupled to the power conversion module 111 and the microprocessor 121, and is exposed on the panel 1F through the second opening 1F2. More specifically, the N luminous button switches 125 are coupled to the power conversion module 111 and the microprocessor 121, and face the N pressable areas 1FP. Furthermore, the at least one electrical connector 126 is coupled to the power conversion module 111 and the microprocessor 121, and the panel 1F is exposed through the third opening 1F3.

In practical applications, the microprocessor 121 couples the power conversion module 111 and the N power switching units 112, and the electrical connector 126 can be but is not limited to a USB Type-A electrical connector, a USB Type-C electrical connector, or a Thunderbolt electrical connector. Furthermore, each socket 12S includes a first jack 12L, a second jack 12N, a third jack 12G, a first contact terminal located in the first jack 12L and coupled to the power switching unit 112, and a first contact terminal located in the second jack 12N. A second contact terminal located in the neutral wire and coupled to the neutral wire, and a third contact terminal located in the third jack hole 12G and coupled to the ground wire, or only includes the first jack hole 12L, the second jack hole 12N, the first contact terminal, and the second contact terminal.

According to the present invention, the second circuit component 12 further includes a memory 12M, and the memory 12M stores at least one application, which is executed by the microprocessor 121 to perform multiple functions, including but not limited to: managing the power supply/disconnection of each socket 12S, power management, power monitoring, USB charging, and indoor environment adjustment.

(1) Manage the power supply/disconnection of each socket for 12 seconds.

As shown in Figure 3, a power plug of a load device 8 is inserted into a socket 12S of the smart socket device 1 of this invention, and the microprocessor 121 is configured to perform: Based on a first wireless signal received by the wireless signal processor 122 from a user terminal electronic device 6 or a second wireless signal received by the wireless signal processor 122 from a control terminal electronic device 7, control the corresponding power switching unit 112 to perform a first switching operation, so that the first contact terminal is coupled to the live wire; and Based on a third wireless signal received by the wireless signal processor 122 from the user terminal electronic device 6 or a fourth wireless signal received by the wireless signal processor 122 from the control terminal electronic device 7, the corresponding power switching unit 112 is controlled to perform a second switching operation to disconnect the electrical connection between the first contact terminal and the live wire.

In practical applications, a control end electronic device 7 can be set up in the indoor environment, such as a gateway, which is also commonly known as a gateway in the industry. Specifically, the control end electronic device 7 is used to convert a special wireless protocol signal into a Wi-Fi signal, where the special wireless protocol signal can be but is not limited to Zigbee, Thread, Z-Wave, Bluetooth or Matter. In other words, the wireless signal processor 122 can send or receive special wireless protocol signals to the control electronic device 7 , and the control electronic device 7 sends Wi-Fi signals to the client electronic device 6 . It is easy to understand that, without using the control terminal electronic device 7 (gateway), the wireless signal processor 122 can send Wi-Fi signals to the client electronic device 6 via the Wi-Fi router, or receive Wi-Fi signals from the client electronic device 6 via the Wi-Fi router.

In one embodiment, the smart socket device 1 supports multiple wireless communication protocols and communicates flexibly with the control terminal electronic device 7 (gateway) or Wi-Fi router through its built-in wireless signal processor 122. Specifically, when the system is deployed in an environment requiring cross-protocol communication, the control terminal electronic device 7 (such as a multi-protocol gateway supporting Zigbee, Thread, Z-Wave, or Matter) can be configured to receive special wireless protocol signals from the socket device, convert them into Wi-Fi signals, and transmit them to the client electronic device 6. Conversely, when the client device 6 sends a Wi-Fi command, it can also be converted into the corresponding protocol signal through the gateway and transmitted back to the socket device, thus achieving communication bridging. To further enhance flexibility and reduce reliance on external gateways, the wireless signal processor 122 of this invention can employ a SoC chip supporting multiple protocols (such as the EFR32 or nRF52840 supporting 802.15.4), and implement a selective protocol stacking mechanism at the firmware layer. It can switch between enabling protocols such as Zigbee, Thread, or Matter according to site requirements, achieving protocol coexistence at the software level. This mechanism avoids interference between protocols and allows the socket device to adaptively switch protocols in different communication scenarios. Specifically, if the presence of a Thread domain is detected, the Thread Stack is automatically enabled for communication. In a gateway-less environment, the system switches to the Wi-Fi Stack and connects directly to the Wi-Fi router. Regarding support scope, Zigbee is suitable for low-power, short-range sensing and control, while Thread supports IPv6 and Mesh architecture, making it suitable for large-scale smart home deployments. With Wi-Fi providing high-speed connectivity for pairing and initial setup, this invention fully realizes cross-protocol interoperability and collaborative operation within a single device through hardware multi-protocol modules and selective firmware protocol switching.

Figures 8A and 8B are the first and second operation diagrams of the user terminal electronic device 6 shown in Figure 3, respectively. It is easy to understand that the manufacturer of the smart socket device 1 of this invention will provide a user control application for the user to install on their user terminal electronic device 6 (e.g., a smartphone). Thus, operating the user control application can remotely manage the power supply/disconnection of each socket 12S. Specifically, as shown in Figure 8B, after the user operates the user control application, the user terminal electronic device 6 sends the third wireless signal or sends the fourth wireless signal through the control terminal electronic device 7 to the smart socket device 1, enabling the microprocessor 121 to control the corresponding power switching unit 112 to perform a second switching operation to disconnect the electrical connection between the first contact terminal and the live wire. Conversely, as shown in Figure 8A, after the user operates the user control application, the user terminal electronic device 6 sends the first wireless signal or sends the second wireless signal through the control terminal electronic device 7 to the smart socket device 1, enabling the microprocessor 121 to control the corresponding power switching unit 112 to perform a first switching operation, so that the first contact terminal is coupled to the live wire.

In actual application, the client electronic device 6 may be but is not limited to a smart phone, a tablet computer, a smart TV, a smart watch, or a notebook computer. On the other hand, the control terminal electronic device 7 may be, but is not limited to, a gateway developed by the manufacturer of the smart socket device 1, Google Nest Mini developed by Google, HomePod mini (commonly known as a user control application speaker) developed by Apple, Amazon Echo Plus (commonly known as an Amazon speaker) developed by Amazon, or Aqara developed by Jarvis Technology. In this way, the user can also control the smart socket device 1 to manage the power supply/off of each socket 12S by operating the user control application on the mobile phone, using Siri voice control, or using Google assistant voice control.

In addition, as shown in Figures 3, 4A and 4B, the user can also directly press a pressable area 1FP on the panel 1F to press the corresponding light-emitting button switch 125. Correspondingly, the microprocessor 121 is configured to perform: responding to a first press operation of the luminous push-button switch 125, controlling the corresponding power switching unit 112 to perform the first switching operation so that the first contact terminal is coupled to the live wire, while simultaneously controlling a light-emitting element mounted on the corresponding luminous push-button switch 125 to emit light; responding to a second press operation of the luminous push-button switch 125, controlling the corresponding power switching unit 112 to perform the second switching operation to disconnect the electrical connection between the first contact terminal and the live wire, while simultaneously controlling the light-emitting element mounted on the corresponding luminous push-button switch 125 to stop emitting light.

(2) Electricity Management

By editing the power management schedule in the user control application, the user can manage the power consumption of one or more load devices 8 (such as air purifiers, fans, televisions, etc.). Correspondingly, the microprocessor 121 is configured to perform: Controlling the corresponding power switching unit 112 to perform the second switching operation according to a power management schedule received from the user terminal electronic device 6 or the control terminal electronic device 7, so that the corresponding first contact terminal is disconnected from the live wire for at least one power outage time interval; and Controlling the corresponding power switching unit 112 to perform the first switching operation according to the power management schedule, so that the corresponding first contact terminal is electrically connected to the live wire for at least one power consumption time interval.

(3) Electricity monitoring

As shown in Figures 4A, 4B, and 7, in the second circuit component 12, the power monitoring chip 127 is coupled to the power conversion module 111, the microprocessor 121, and each of the first contact terminals. It measures and obtains the power consumption value of the corresponding load device 8 from the first contact terminals and transmits the power consumption value of the load device 8 to the microprocessor 121. Thus, the microprocessor 121 can calculate the power consumption of the load device 8 based on the power consumption value and transmit the power consumption value and power consumption of the load device to the user terminal electronic device 6 via the wireless signal processor 122, or via the control terminal electronic device 7. Furthermore, when the power consumption of the load device 8 exceeds a predetermined power threshold, the microprocessor 121 controls the corresponding power switching unit 112 to perform the second switching operation to disconnect the electrical connection between the first contact terminal and the live wire, thereby stopping the power supply to the load device 8.

In addition, the power monitoring chip 127 can continuously monitor the current and voltage values flowing through the first contact terminal, and thereby determine whether there is an abnormal power consumption condition, such as surge current, sudden power increase, or power consumption behavior that continues to exceed the normal range. When the load device 8 is detected to be operating under overload or experiencing an abnormal power consumption condition, the power monitoring chip 127 will immediately report the abnormal event to the microprocessor 121, which will then trigger a control signal to cause the power switching unit 112 to urgently perform a second switching operation, quickly disconnecting the electrical connection between the first contact terminal and the live wire, so as to achieve the effect of automatic power-off protection. The abnormal event and the corresponding protection action can also be simultaneously sent to the user terminal electronic device 6 and the control terminal electronic device 7 through the wireless signal processor 122, so that the user can keep abreast of the equipment status and carry out subsequent processing.

In this smart power socket, to enhance the monitoring of electrical safety of the load device 8, in addition to the power monitoring chip 127 continuously measuring and calculating the load power consumption and accumulated power consumption, a leakage current detection technology module can be further integrated to achieve active protection under abnormal power conditions. Specifically, the second circuit component 12 can be configured with a residual current detection unit (RCDU), which detects whether there is an abnormal current difference between the live wire and the neutral wire, that is, whether there is current leakage to the ground wire. When the residual current detection unit detects that the leakage current exceeds a preset leakage current threshold (e.g., 10mA or 30mA, depending on the requirement), it generates a leakage current warning signal and sends it to the microprocessor 121. The microprocessor 121 then activates the power switching unit 112 to perform a second switching operation, quickly disconnecting the electrical connection between the first contact terminal and the live wire, immediately stopping the power supply to the load device 8, thus achieving the purpose of leakage current protection. Simultaneously, it can also send a notification to the user terminal electronic device 6 via the wireless signal processor 122. This design not only reduces the risk of electric shock and fire caused by equipment aging or insulation damage, but also enhances the electrical safety protection capability of this smart power socket.

(4)USB charging

As shown in Figures 4A, 4B, and 7, the first circuit component 11 further includes a power management chip 113, which is coupled to the microprocessor 121 and the at least one electrical connector 126, and coupled to the second output filter unit 1C22. Furthermore, the power management chip 113 is configured to perform the following: adjust the current value contained in the third power signal received by the at least one electrical connector 126 from the second output filter unit 1C22 according to a control signal from the microprocessor 121. Simply put, after an electrical connector of a transmission line of an electronic device (such as a smartphone, tablet, or power bank) is connected to an electrical connector 126, the microprocessor 121 can manage the charging process of the electronic device through the power management chip 113, thus implementing USB charging functionality.

The first circuit component 11 may include multiple sets of electrical connectors 126 corresponding to different types of transmission interfaces, including at least one first-type connector (e.g., USB Type-A), at least one second-type connector (e.g., USB Type-C), and an optional high-speed transmission connector (e.g., a USB Type-C connector supporting the Thunderbolt protocol). Each of the electrical connectors 126 is respectively coupled to the second output filter unit 1C22 and the power management chip 113, and operates in coordination with the control signals output by the microprocessor 121. The power management chip 113 is further configured to automatically adjust the output voltage and current parameters according to the detected electronic device connection type and its charging protocol (e.g., USB BC1.2, USB PD, Quick Charge, Thunderbolt Power Delivery, etc.). For example, when an electronic device that supports a USB Type-A connector (such as a power bank or an older smartphone) is connected to the corresponding electrical connector, the power management chip 113 outputs a fixed voltage (such as 5V) and a corresponding current (such as 2.4A). When a laptop or tablet supporting USB PD is connected via a USB Type-C connector, it can negotiate multiple voltage levels (such as 5V, 9V, 12V, 15V, 20V) and current (up to 5A) according to the device's needs, achieving high-efficiency charging. The smart socket device can integrate a USB Type-C connector with a power management chip that supports the USB Power Delivery (PD) protocol, and through the collaboration of the microprocessor 121 and the PD controller, dynamically adjust the output voltage and current (such as 5V/3A, 9V/3A, 20V/5A) according to the power requirements (such as Power Data Object, PDO) proposed by the connected device in the PD protocol to support high power output. When the connected device is a Thunderbolt-compatible device, the Type-C connector can still be used for power supply and device identification (such as VID/PID), while retaining high-speed data transmission capabilities.

(5) Indoor environment regulation

As shown in Figure 3, the smart socket device 1 of this invention is coupled to a control module of the electric blind 5, a control device of the electrically controlled color-changing window 4, a light switch of the light fixture 2, and the electrical control box of the air conditioning equipment 3 via a wired or wireless interface. Correspondingly, the microprocessor 121 is configured to perform the following: Receive a temperature sensing signal from the temperature sensor 123 and process the temperature sensing signal to obtain an ambient temperature; Receive an ambient light sensing signal from the ambient light sensor 124 and process the ambient light sensing signal to obtain an ambient brightness; Transmit the ambient temperature and the ambient brightness to the client electronic device 6 or the control terminal electronic device 7 via the wireless signal processor 122; When the ambient temperature exceeds a predetermined temperature threshold, the control module enables the curtain drive mechanism of the electric curtain 5 to operate forward, so that the curtain fabric of the electric curtain 5 covers at least one window; when the ambient brightness is below a predetermined ambient brightness threshold, the control module enables the curtain drive mechanism to operate in reverse, so that the at least one window is not covered by the curtain fabric; when the ambient temperature exceeds the predetermined temperature threshold, the control device generates a first voltage to a color-changing window of the electrically controlled color-changing window to reduce the transparency of the color-changing window. When the ambient brightness is lower than a predetermined ambient brightness threshold, the control module is enabled to generate a second voltage to the color-changing window to increase its transparency; when the ambient brightness is higher than a predetermined upper brightness threshold, the light switch is enabled to perform a first switching operation to turn off at least one light fixture 2; when the ambient brightness is lower than a predetermined lower brightness threshold, the light switch is enabled to perform a second switching operation to turn on at least one light fixture 2; when the ambient temperature is higher than a predetermined upper temperature threshold, the air conditioning unit 3 is enabled to start operation; and When the ambient temperature is lower than a predetermined valve value, the air conditioning equipment 3 is enabled to stop operating.

In one application embodiment of the smart socket device 1, the microprocessor 121 performs conditional comparison and logical judgment on multiple sets of parameter values pre-stored in memory based on real-time data returned by the temperature sensor 123 and the ambient light sensor 124. These parameters include: a preset temperature threshold (T₁) for ambient temperature, a preset ambient brightness threshold (L₁) for ambient brightness, a preset upper brightness threshold (L₂) and a preset lower brightness threshold (L₃) for lighting control, and a preset upper temperature threshold (T₂) and a preset lower temperature threshold (T₃) for air conditioning control. By logically combining these parameters, the system can accurately determine whether various devices need to be turned on or off to meet the needs of indoor comfort and energy saving efficiency in different scenarios. For example, in energy-saving applications, when the ambient temperature T is higher than T₁ (e.g., T₁ = 28°C), the microprocessor 121 will control the curtain control module to drive the curtain mechanism to operate in the forward direction, pull down the electric curtain 5, and block the window to reduce the contribution of sunlight to the indoor temperature rise. Meanwhile, if the ambient light intensity L > L₂ (e.g., L₂ = 800 lux), indicating sufficient indoor brightness, the first switch operation of the light fixture is executed to turn off light fixture 2 and avoid redundant lighting. Conversely, if L < L₃ (e.g., L₃ = 300 lux), the second switch operation is executed to turn on the lighting system to supplement the light source. If L < L₁ (ambient light intensity preset threshold, e.g., L₁ = 500 lux) and the temperature is also lower than T₁, indicating that both light and temperature are at a low level, the microprocessor 121 will control the electric blinds to retract in the opposite direction to increase natural light, and at the same time increase the transparency of the electrically controlled color-changing window to further introduce natural light. Each switch can be paired via software (application) on a smartphone to achieve dual control, thereby reducing the wiring and subsequent maintenance costs required for actual setup and lowering overall costs. For example, in long-term care facilities, to address the sensitivity of the elderly to changes in temperature and brightness, more stringent valve settings can be used, such as T₁ = 26°C, T₂ = 28°C, T₃ = 24°C, L₁ = 400 lux, L₂ = 600 lux, L₃ = 300 lux, to reduce discomfort caused by excessive changes. When T > T₂ or T < T₃, not only is the air conditioning controlled, but a warning can also be sent to the control terminal electronic device 7 for manual intervention. Simultaneously, the system can be configured to adjust the light intensity (L₃) based on day and night schedules, setting it to the lowest possible brightness in the morning. For example, if L < L₃ in the early morning, the system will slowly dim the lights to 150 lux to avoid strong light stimulation. In hotel room scenarios, the system can also use user preferences (downloaded from the control unit 7 to the smart socket device 1) as the basis for various valve values. For instance, if a guest sets the nighttime ambient temperature to 24°C and the brightness control valve values to 400 lux and 200 lux, the system will turn on the bedside lamp and dim it to a warm color (2700K) when L < 200 lux, providing soft lighting, while automatically activating the air conditioning to maintain comfort when T > 24°C.

In one aspect of this invention, the smart socket device can be a modular pluggable device that allows users to flexibly expand or replace functional modules according to actual application needs. These modules include a relay control module, a USB power output module (supporting Type-A, Type-C, and Thunderbolt), an environmental sensing module (temperature and light sensors), and a multi-protocol wireless communication module (such as Wi-Fi, Zigbee, and Thread). Each module connects to the microprocessor 121 via standardized connectors, supporting plug-and-play and hot-swappable design for easy maintenance and upgrades. At the implementation level, this socket device can operate independently, performing local power consumption monitoring, automatic overload protection, and remote control tasks. It can also be integrated into a large-scale smart home system via control terminal electronic devices (such as gate devices) to achieve cross-device linkage and scenario-based automated control. This modular architecture provides flexibility, high compatibility, and ease of long-term maintenance.

This smart socket device not only possesses basic safety functions such as power monitoring, overload protection, and leakage detection, but can also be further integrated with other smart home appliances through the wireless signal processor 122 to achieve systematic smart control of multiple devices. For example, when the power monitoring chip 127 detects abnormal power consumption of the load device 8 (such as excessive temperature rise, surge current, or leakage) and triggers power-off protection, the microprocessor 121 can simultaneously issue linkage commands through the control terminal electronic device 7 to control other IoT devices to perform emergency response measures. For example, triggering the smart door lock to automatically unlock for easy escape; simultaneously activating the alarm system and indoor camera for recording and cloud transmission; or notifying the user terminal electronic device 6 to push abnormal event alerts. This cross-device collaborative response mechanism, which combines leakage current detection with smart network devices, not only enhances indoor electrical safety but also provides real-time warnings and disaster response functions, making it suitable for a variety of applications such as smart homes, elderly care, and industrial protection.

In summary, this invention can achieve real-time detection, power consumption monitoring, and power protection.
