[0002] In schools, especially student dormitories, the high density of people and electrical appliances creates significant electrical safety hazards, particularly the use of high-power appliances such as hair dryers, water heaters, and induction cookers. These appliances can easily cause injuries or even fires due to leakage or short circuits. Therefore, the use of high-power appliances should be restricted in densely populated areas like student dormitories.
[0003] Moreover, due to poor user habits, many users often forget to unplug appliances or leave them plugged in after use. Leaving appliances plugged in for extended periods when no one is home poses a significant safety hazard. If an appliance short-circuits or the circuit is damaged, it could easily cause a fire without anyone noticing, resulting in huge losses. Therefore, appliances that do not need to be kept plugged in should be turned off when no one is home. Utility Model Content

Detailed Implementation
[0039] The technical features of this utility model will be further described in detail below with reference to the accompanying drawings so that those skilled in the art can understand them.
[0040] A smart power strip capable of automatic monitoring, its mechanical structure is as follows: Figure 1 and Figure 2As shown, it includes: a main shell 1 and a power cord 2. Inside the main shell 1, there is a DC socket module 3 and several AC socket modules 4. There is also a main control circuit board 5 for realizing intelligent control. The main control circuit board 5 is electrically connected to a drive circuit board 6 for driving and controlling the power supply of the AC socket modules 4. The main control circuit board 5 is also electrically connected to a first human body detection module 7 for detecting whether there is a person within the sensing range of the smart power strip.
[0041] In the mechanical structure of this smart power strip, both the DC socket module 3 and the AC socket module 4 are modularly designed, facilitating the production and assembly of different models of the smart power strip. Furthermore, the number of DC socket modules 3 and AC socket modules 4 can be designed in different combinations according to actual application scenarios to meet the personalized needs of different groups and application scenarios. For example, if a student dormitory desk is designated as a study area, the smart power strip used in the study area is suitable for assembly by at least three AC socket modules 4, at least two DC socket modules 3, and the display module 17. If a student dormitory bed is designated as a rest area, the smart power strip used in the rest area does not require the AC socket module 4; instead, it can be assembled by assembly by at least two DC socket modules 3 and the display module 17.
[0042] Its circuit structure is as follows Figures 3 to 14 As shown, the circuit structure on the main control circuit board 5 includes a main control circuit 8, a power conversion circuit 9, and a sensor connection port; the circuit structure on the drive circuit board 6 includes a first step-down circuit 10, a drive control circuit 11, a socket input control circuit 12, and an output power detection circuit 13. The main control circuit 8 is electrically connected to the drive control circuit 11.
[0043] The circuit operation of this smart power strip is as follows:
[0044] The output power detection circuit 13 detects the power output information of the corresponding AC socket module 4 from the neutral line. When the output power exceeds the threshold, the output power detection circuit 13 feeds back the power abnormality signal to the drive control circuit 11. The drive control circuit 11 outputs a power-off signal to the socket input control circuit 12. Since a relay is provided on the live wire at the input terminal of the socket input control circuit 12, the relay can be turned on and off by the output signal of the drive control circuit 11, thereby realizing the on and off control of the power output of the corresponding AC socket module 4.
[0045] When the first human detection module 7 does not detect human information within a set extended period of time, the main control circuit 8 outputs a power-off control signal to all or part of the drive control circuits 11, thereby driving the corresponding socket input control circuit 12 to cut off the power. This enables automatic power-off operation of all or part of the AC socket modules 4 when no one is in the room, effectively preventing leakage, short circuits, and other situations caused by electrical appliances being powered on for extended periods when no one is in the dormitory, reducing the risk of fire and eliminating potential safety hazards in dormitory electricity use.
[0046] In addition, the smart power strip samples and detects the output power of the corresponding AC socket module 4 through the output power detection circuit 13. When the output power exceeds the set threshold, the red indicator light illuminates to issue an alarm reminder. Within a set time, the drive control circuit 11 controls the socket input control circuit 12 to perform a power-off operation, thereby effectively limiting the use of high-power appliances.
[0047] Specifically, the smart power strip also includes a control socket 23, which includes a mounting shell 24 and wires 25. A control circuit board 26 and several DC socket modules 3 are housed within the mounting shell 24. The control circuit board 26 is electrically connected to a second human detection module 27, and is electrically connected to the main control circuit board 5 via the wires 25. The circuit structure on the control circuit board 26 includes a second step-down circuit 28 and a second human detection module connection port 29. In university dormitories, where bunk beds with desks underneath are common, this smart power strip can be used... The main body of the power strip is installed on the desk below, and the sub-control socket 23 is installed on the bed above. Both the main body of the smart power strip and the sub-control socket 23 are intelligently controlled by the main control circuit board 5. At the same time, the first human body detection module 7 and the second human body detection module 27 respectively perform human body detection to determine whether there is a person in the corresponding position. This makes it convenient for users to use electricity and can cut off the power in time after the user leaves for a set period of time, avoiding electricity waste and reducing electrical safety hazards. This smart power strip with sub-control sockets is very suitable for the use of electricity in college student dormitories.
[0048] Specifically, the number of drive circuit boards 6 does not exceed the number of AC socket modules 4, and each drive circuit board 6 corresponds to one AC socket module 4. If the number of drive circuit boards 6 is the same as the number of AC socket modules 4 and they correspond one-to-one, the output power of each AC socket module 4 is limited, and a power-off operation is performed when the output power exceeds a set threshold. In order to increase the applicable scenarios of this smart power strip and avoid high-power appliances being unable to be used, the number of drive circuit boards 6 can be reduced, leaving a few AC socket modules 4 as ordinary sockets for normal use of high-power appliances.
[0049] Furthermore, both the first human body detection module 7 and the second human body detection module 27 employ infrared sensors, which are highly sensitive and capable of both dynamic and static detection. The sensor connection ports include a first human body detection module connection port 14 and a temperature sensor connection port 15. The first human body detection module connection port 14 is used to electrically connect to the infrared sensor to detect human radiation information. The temperature sensor connection port 15 is used to electrically connect to the temperature sensor to detect the ambient temperature around the smart power strip, enabling fire monitoring. In case of excessively high temperatures that may lead to a fire, the power can be cut off immediately to prevent the fire from spreading due to electrical leakage or short circuits. At the same time, to enhance fire detection and monitoring, a smoke sensor connection port 16 can also be provided to electrically connect to the smoke sensor. In case of high indoor smoke concentration that may lead to a fire, the power can be cut off immediately, thereby enhancing electrical safety and preventing electrical fires.
[0050] Specifically, the main body shell 1 is provided with a display module 17 and several indicator lights 18 that are electrically connected to the main control circuit 8. The display module 17 is a digital tube or a display screen. The display module 17 is used to display the power consumption status of the electrical appliances on the smart power strip, such as power consumption and power consumption time. The indicator lights 18 correspond one-to-one with the AC socket module 4. When an electrical appliance is plugged into the AC socket module 4 and the output power is normal, the corresponding indicator light 18 emits white light. When the power of the electrical appliance plugged into the AC socket module 4 is too high and an overload occurs, the corresponding indicator light 18 emits red light.
[0051] In addition, the DC socket module 3 is equipped with a USB socket, a Type-C socket and a circular DC socket. The DC socket module 3 integrates three commonly used power interfaces, which can realize fast charging function. At the same time, the integrated power interface can reduce the area occupied by the power plug, so that the smart power strip can connect more electrical devices at the same time.
[0052] Specifically, the main control circuit 8 is electrically connected to a WiFi module 19 for remote monitoring. The WiFi module 19 enables wireless communication between the smart power strip and user mobile phones and other terminal devices. Through the WiFi module 19, the power consumption information of the smart power strip is transmitted to the user's mobile phone, allowing the user to remotely monitor the power consumption status and perform remote operation, controlling the smart power strip to cut off or maintain power to a certain appliance.
[0053] In addition, the main control circuit 8 is electrically connected to a button circuit 20 for timed power limiting and manual control of the power supply of the smart power strip. Touch-sensitive or mechanical buttons can be provided on one side of the display module 17 corresponding to the button circuit 20. When a user touches or presses a button, the button circuit 20 outputs a button signal to the main control circuit 8. When the main control circuit 8 receives a connection signal from the WiFi module 19, the smart power strip is online. At this time, if the main control circuit 8 receives a corresponding button signal, it will release the power limiting on the AC socket module 4 within a set time period, even if the current output power... If the power consumption exceeds a set threshold, the AC socket module 4 will remain on for a period of time to facilitate the use of high-power appliances such as hair dryers in student dormitories and reduce the risk of using high-power appliances in student dormitories. When the main control circuit 8 does not receive a connection signal from the WiFi module 19, the smart power strip is in an offline state. At this time, if the main control circuit 8 receives a button signal, it will act as a button switch to control the power supply of the smart power strip. At the same time, corresponding to the button circuit 20, there are two buttons. When both buttons are pressed at the same time, the activation and deactivation of the WiFi module 19 can be controlled, making it easy for the smart power strip to switch between online and offline states.
[0054] In addition, the main control circuit 8 is electrically connected to an AC power switch circuit 21 for wirelessly controlling the power supply of the AC socket module 4 as a whole, and a DC power switch circuit 22 for wirelessly controlling the power supply of the DC socket module 3. The user can send control commands to the main control circuit 8 through the WiFi module 19. The main control circuit 8 performs power-off or power-on control on all the AC socket modules 4 through the AC power switch circuit 21. Similarly, the main control circuit 8 performs power-off or power-on control on the DC socket module 3 through the DC power switch circuit 22, thereby realizing remote control of the smart power strip.
