[0002] With the rapid development of internet technology, smart home systems are gradually popularized, and internet switches, as one of the core control components of smart home systems, are increasingly important. Internet switches not only have the basic functions of traditional power switches, such as controlling the on-off of electrical equipment, but also integrate advanced functions such as remote control and intelligent linkage, greatly improving the convenience of users' lives.

[0003] However, in the design of traditional internet switches, electrical safety performance is often overlooked. In the face of circuit overload, short circuit or high temperature and other abnormal situations, traditional internet switches lack effective safety protection measures, which can easily cause serious safety hazards such as fire. For example, CN113097000B discloses a power switch, which improves the structural stability and convenience of the switch to a certain extent, but is still insufficient in electrical safety protection and fails to effectively respond to the fire risk that may be caused by abnormal circuit conditions.

[0004] Specifically, the existing internet switches in the prior art mainly have the following problems in electrical safety:

[0005] Lack of real-time monitoring mechanism: traditional internet switches cannot monitor the circuit state in real time, such as current, voltage and temperature and other key parameters, which leads to the inability to respond in time when the circuit is abnormal, increasing the possibility of fire.

[0006] Single protection measures: some internet switches are equipped with certain protection measures, such as overcurrent protection, short circuit protection, etc., but these measures are often single and slow to react, making it difficult to effectively respond to complex and variable circuit abnormal conditions.

[0007] Insufficient intelligence: in today's increasingly intelligent smart home systems, the intelligence of traditional internet switches in electrical safety protection is obviously insufficient, which cannot be deeply integrated with smart home systems, limiting the further improvement of their safety protection functions.

[0008] Low user participation: the existing internet switches in the prior art often lack user participation mechanisms in electrical safety protection, and users cannot real-time understand the working state of the switch and the circuit safety situation, nor can they make individualized settings and adjustments according to actual needs.

[0009] To solve the above problems, the application provides a fireproof internet switch, aiming to realize real-time monitoring and rapid response to the circuit state by integrating advanced electrical protection technology and intelligent monitoring function, effectively preventing fire accidents caused by electrical faults. The application not only improves the safety and reliability of the internet switch, but also further promotes the development of smart home systems in a safer and more intelligent direction.

DETAILED DESCRIPTION

[0038] The technical scheme in the utility model will be further described below in connection with the drawings and embodiment.

[0039] Embodiment 1

[0040] As Figs. 1 to 4 shown, the embodiment describes the basic structure, component configuration and detailed working process of an Internet switch with fireproof arc breaking function.

[0041] 1. Basic structure:

[0042] The fireproof Internet switch mainly consists of the following parts: device body 1, switch arc breaking mechanism 2 and fireproof mechanism 3.

[0043] Device body 1: as the overall framework, it provides the basis for installation and fixation of other components.

[0044] Switch arc breaking mechanism 2:

[0045] Machine body 21: it is the main bearing component of the switch arc breaking mechanism, and the lower end is inserted with a connecting wire 22 for introducing current from the external circuit into the switch.

[0046] Connecting wire 22: made of high-conductivity material, it ensures the efficiency and stability of current transmission. Its lower end is in close contact with the connecting contact 37 in the fireproof mechanism 3, realizing the closing and opening of the circuit.

[0047] Mounting piece 23: installed at both ends of the machine body 21, it is used to firmly install the switch arc breaking mechanism 2 on the device body 1, and facilitates the overall installation and fixation.

[0048] Fireproof mechanism 3: installed at the lower end of the switch arc breaking mechanism 2, it is the core component for realizing the fireproof function of the invention.

[0049] Machine box 31: it provides a protective shell for the fireproof mechanism, and other key components are installed inside.

[0050] Positioning seat 32: installed inside the machine box 31, it is used to position and fix the plug-in 33, ensuring its stability and accuracy during movement.

[0051] Plug-in 33: one end is installed with a sliding block 34, and the other end is installed with a connecting contact 37. The plug-in 33 can move up and down inside the positioning seat 32, realizing the opening and closing of the circuit.

[0052] Sliding block 34: installed at one end of the plug-in 33, it slides with the inner wall of the positioning seat 32, ensuring smooth up and down movement of the plug-in 33.

[0053] Bimetallic strip 35: installed inside the machine box 31, it is in close proximity to the plug-in 33. When the circuit overheats, the bimetallic strip 35 bends due to material properties, driving the plug-in 33 to move downward.

[0054] Elastic member 36: installed at the lower end of the plug-in 33, and adheres to the inner wall of the positioning seat 32. When the bimetallic strip 35 returns to the normal shape, the elastic member 36 resets the plug-in 33 to the initial position, so that the connecting contact 37 recontacts with the connecting wire 22.

[0055] Connecting contact 37: installed at the upper end of the plug-in 33, used for contacting or separating with the connecting wire 22, realizing the closing and opening of the circuit.

[0056] 2. Work flow:

[0057] (1) Normal working state:

[0058] The connecting wire 22 introduces the current into the switch through the connecting contact 37, and the circuit is in the closed state, and the device works normally;

[0059] The bimetallic strip 35 remains flat, and does not exert any force on the plug-in 33;

[0060] The elastic member 36 is in a natural elongation state, keeping the plug-in 33 in the initial position.

[0061] (2) Circuit overheating condition:

[0062] When the heat in the circuit is too high, the bimetallic strip 35 bends due to the material characteristics (such as different thermal expansion coefficients of different metals);

[0063] The bending of the bimetallic strip causes it to exert a downward force on the plug-in 33, driving the plug-in 33 to move downward;

[0064] When the plug-in 33 moves downward, the connecting contact 37 separates from the bottom of the connecting wire 22, the circuit is disconnected, and the power is quickly cut off;

[0065] The elastic member 36 is compressed and stores energy for resetting.

[0066] (3) Circuit temperature drop condition:

[0067] As the temperature of the circuit decreases, the bimetallic strip 35 gradually returns to the normal shape, and the downward force on the plug-in 33 gradually decreases;

[0068] When the bimetallic strip 35 completely returns to the normal shape, the elastic member 36 releases the stored energy and resets the plug-in 33 to the initial position;

[0069] The connecting contact 37 recontacts with the connecting wire 22, and the circuit returns to the closed state, and the device returns to normal work.

[0070] Through the above detailed structure description and work flow refinement, the same technical personnel in the same technical field can successfully reproduce the technical solution of the present application only by this description.

[0077] The output of the current transformer is an analog signal representing the real-time waveform of the live line current.

[0078] (2) Analog-to-Digital Converter (ADC):

[0079] Converts the analog signal collected by the current transformer into a digital signal. The resolution and sampling rate of the ADC are crucial for subsequent data processing and analysis;

[0080] The ADC used in this embodiment has high resolution and high sampling rate to ensure the accuracy and real-time nature of the digital signal.

[0082] Uses an ARM-Cortex-M processor as the core, responsible for data acquisition, processing, and analysis;

[0083] The data processing unit is built-in with wavelet analysis and AlexNet convolutional neural network algorithms for intelligent analysis and fault judgment of the collected current waveform data;

[0084] The data processing unit is also responsible for communication and data exchange with other modules (such as communication module, wireless circuit breaker, etc.).

[0085] (4) Storage unit:

[0086] Used to store algorithm models, historical data, configuration parameters, and other necessary information;

[0087] The storage unit uses non-volatile memory (such as Flash memory) to ensure data persistence and reliability.

[0088] 2. Workflow:

[0090] The current transformer collects real-time waveform data of the live line current and outputs it as an analog signal;

[0091] After appropriate conditioning circuit (such as filtering, amplification, etc.), the analog signal is input to the ADC for conversion.

[0092] (2) Analog-to-digital conversion:

[0093] The ADC converts the analog signal to a digital signal and transmits the digital signal to the data processing unit;

[0094] The data processing unit pre-processes the digital signal (such as normalization, denoising, etc.) to improve the accuracy of subsequent analysis.

[0095] (3) Intelligent analysis and fault judgment:

[0096] The data processing unit uses wavelet analysis and AlexNet convolutional neural network algorithms to intelligently analyze the pre-processed digital signal;

[0097] By comparing with the preset algorithm model, the data processing unit can identify potential fire hazards such as weak discharge arc;

[0098] Once a fault current or potential fire hazard is detected, the data processing unit will immediately trigger an alarm mechanism and send a signal to the wireless circuit breaker to start power-off protection measures.

[0099] (4) Data storage and communication:

[0100] The data processing unit stores the analysis results and fault information in the storage unit for subsequent analysis;

[0101] At the same time, the data processing unit also communicates with the user's mobile phone APP in real time through the communication module and synchronizes the data, so that the user can remotely monitor the switch state and receive alarm information.

[0102] (5) Fault handling and recovery:

[0103] When a fault current is detected, the wireless circuit breaker will quickly cut off the power supply to prevent fire spread and accidents;

[0104] After fault handling is completed, the data processing unit will re-collect and analyze the current waveform to confirm that the circuit has returned to normal working state;

[0105] If the circuit has returned to normal working state, the data processing unit will send a notification to the user's mobile phone APP to inform the user that the fault has been eliminated.

[0106] Through the above detailed structural description and workflow refinement, the same technical field of professional and technical personnel can only rely on this description to successfully reproduce the technical solution of the current waveform acquisition and analysis module in the embodiment.
