[0070] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0071] In the field of industrial lighting control, human detection devices using cameras are widely used, especially in complex scenarios where accurate human identification is required.

[0072] However, existing human detection devices face numerous challenges: high false trigger rates, frequent software malfunctions, and reliance on high-quality, high-resolution camera hardware, all of which limit their application in harsh industrial environments. Especially in complex operations and multi-object structures, the accuracy of human presence detection and the timeliness of information extraction are extremely critical. Traditional human detection devices primarily rely on images or video streams captured by cameras for simple human presence detection, lacking the ability to classify and detect people and extract in-depth information in complex environments. This leads to inaccurate detection and frequent false triggers, reducing product reliability and user experience.

[0073] To address the aforementioned issues, this application proposes an AI human detection device. By combining AI human detection algorithms, it ensures accurate and timely detection of human presence even in complex environments with numerous interfering factors, effectively avoiding false triggering or missed triggering. Compared to existing products on the market, it offers higher reliability, more stable information transmission, smaller footprint, and lower cost, providing an ideal choice for users in industries with high reliability requirements. The specific implementation principle will be described in detail in the following embodiments.

[0074] Please see Figure 1 This is a schematic diagram of an AI human detection device in an embodiment of this application. Figure 1 The device includes an AI chip control circuit 110, a digital output circuit 120, and a camera module input circuit 130.

[0075] The AI ​​chip control circuit 110 is connected to the switch output circuit 120 and the camera module input circuit 130, respectively.

[0076] In one feasible implementation, the camera module input circuit 130 is used to generate a shooting signal based on the shooting; the AI ​​chip control circuit 110 is used to receive the shooting signal and perform AI human detection processing on the shooting signal to obtain a human detection result signal; the switch output circuit 120 is used to receive the human detection result signal and determine a switch signal based on the human detection result signal, and the switch signal is used to indicate whether a human figure has been detected.

[0077] AI human detection processing refers to the use of AI human detection algorithms for human detection.

[0078] In some embodiments, the switching signal includes a human-shaped switching signal and a non-human-shaped switching signal. When the switching signal is a human-shaped switching signal, it indicates that a human shape has been detected; when the switching signal is a non-human-shaped switching signal, it indicates that a human shape has not been detected.

[0079] In this application embodiment, a novel human detection device, namely an AI human detection device, is proposed. This device integrates an AI chip control circuit 110, a switch output circuit 120, and a camera module input circuit 130, forming a highly efficient and accurate human detection device. By combining AI human detection algorithms, it ensures that even in complex environments with many interfering objects, the presence of human bodies can be detected accurately and promptly, effectively avoiding false triggering or missed triggering. Compared with existing products on the market, it has higher reliability, more stable information transmission, smaller footprint, and lower cost, providing users with an ideal choice in industries with high reliability requirements.

[0080] Furthermore, the AI ​​human detection device of this application has the following advantages: by integrating advanced AI human detection algorithms, it can learn and adapt to different lighting conditions, background noise, and changes in human posture, thereby maintaining a high level of detection accuracy in various industrial scenarios; it can not only simply detect the presence of human bodies, but also perform more detailed classification and identification of human bodies through AI human detection algorithms, such as distinguishing between workers, visitors, or potential safety hazards. This intelligent enhancement makes the device more widely and deeply applied in fields such as industrial automation and security monitoring; although AI algorithms usually require high computing resources, this application achieves a balance between high efficiency and low power consumption by optimizing the design of the AI ​​chip control circuit 110. This means that while providing high-performance human detection, the device can also effectively control energy consumption, reduce operating costs, and meet the requirements of modern industry for green energy conservation.

[0081] based on Figure 1 Please see Figure 2 This is a schematic diagram of an AI human detection device in an embodiment of this application. Figure 2 The device also includes a light-sensing circuit 210 and an infrared fill light circuit 220.

[0082] Among them, the light sensing circuit 210 and the infrared fill light circuit 220 are both connected to the AI ​​chip control circuit 110.

[0083] In one feasible implementation, the light sensing circuit 210 is used to generate an ambient light intensity signal based on the detected ambient light intensity; the AI ​​chip control circuit 110 is used to receive the ambient light intensity signal and generate a supplementary light control signal when the light intensity value of the ambient light intensity signal is less than the intensity threshold; the infrared supplementary light circuit 220 is used to receive the supplementary light control signal and turn on the infrared supplementary light according to the supplementary light control signal.

[0084] The intensity threshold can be determined and set by the operator based on extensive experience, experiments, or statistics.

[0085] It should be noted that in low-light environments or at night, the captured shooting signal (i.e., image signal) is often blurry. Infrared fill lights, on the other hand, use infrared technology and emit infrared light waves that are invisible to the human eye. This allows them to capture clear shooting signals even at night or in low-light conditions. Furthermore, since the infrared light waves emitted by infrared fill lights are invisible, the AI ​​human detection device of this application is also suitable for locations with high concealment requirements.

[0086] In some embodiments, the light intensity value corresponding to nighttime or low-light environments with insufficient light can be used as the intensity threshold.

[0087] In this embodiment, by introducing a light-sensing circuit 210 and an infrared fill light circuit 220 into the AI ​​human detection device, it is possible to perceive and adapt to different lighting environments in real time. This allows the device to capture clear and accurate image signals even at night or in low-light environments with insufficient light, thereby ensuring the continuity and stability of human detection and improving the accuracy of human detection. It can effectively avoid false triggering or missed triggering problems caused by insufficient light.

[0088] Furthermore, since the infrared light emitted by the infrared fill light is invisible, the AI ​​human detection device of this application will not have a significant impact on the surrounding environment when the infrared fill light is turned on. This feature makes the device more valuable in places where concealment is required, and it can achieve effective human detection without affecting personnel activities and the working environment.

[0089] based on Figure 2 Please see Figure 3 The diagram below is a schematic of the photosensitive circuit in an embodiment of this application. The photosensitive circuit 210 includes a first capacitor C43, a first resistor R36, a second resistor R37, a third resistor R38, and a first chip U7.

[0090] In one feasible implementation, the first pin of the first chip U7 is connected to one end of the first capacitor C43, the fourth pin of the first chip U7 is connected to one end of the third resistor R38, the fifth pin of the first chip U7 is connected to one end of the second resistor R37, and the sixth pin of the first chip U7 is connected to one end of the first resistor R36. The first pin of the first chip U7, the other end of the first resistor R36, the other end of the second resistor R37, and the other end of the third resistor R38 are all connected to a DC power supply. The second, third, and seventh pins of the first chip U7, as well as the other end of the first capacitor C43, are all grounded. The fourth to sixth pins of the first chip U7 are all connected to the AI ​​chip control circuit 110.

[0091] In some embodiments, the first chip U7 serves as the core component of the photosensing circuit 210. Its working principle is based on the photoelectric effect. When the ambient light intensity changes, the voltage or current output by the first chip U7 will change accordingly. These changes are converted into electrical signals (i.e., ambient light intensity signals) and output to the AI ​​chip control circuit 110 through the fourth to sixth pins of the first chip U7. The first capacitor C43 is used to filter the DC power supply. The first resistor R36, the second resistor R37, and the third resistor R38 are used to limit the current of the DC power supply.

[0092] In this embodiment, the designed light-sensing circuit 210 includes components such as a first capacitor C43, a first resistor R36, a second resistor R37, a third resistor R38, and a first chip U7. The light-sensing circuit 210 can accurately sense the ambient light intensity and provide a stable and accurate light intensity signal for the AI ​​human detection device.

[0093] Furthermore, by designing the light-sensing circuit 210 and carefully selecting components and connection methods, this application achieves a compact structure, a moderate number of components, and a reasonable layout for the light-sensing circuit 210. This design not only improves the reliability and stability of the light-sensing circuit 210 but also facilitates integration with other circuit modules, thereby reducing production costs and providing users with a more cost-effective product option.

[0094] based on Figure 2 Please see Figure 4 The diagram below is a schematic of an infrared fill light circuit in an embodiment of this application. The infrared fill light circuit 220 includes a second capacitor C53, a third capacitor C52, a fourth resistor R50, a Schottky diode U9, a first infrared emitting diode LED6, a second infrared emitting diode LED7, a first inductor L6, and a second chip U10.

[0095] In one feasible implementation, the first pin of the second chip U10 is connected to the anode of the Schottky diode U9 and one end of the first inductor L6, respectively. The other end of the first inductor L6 is connected to one end of the third capacitor C52 and the cathode of the second infrared emitting diode LED7, respectively. The anode of the second infrared emitting diode LED7 is connected to the cathode of the first infrared emitting diode LED6, respectively. The fourth pin of the second chip U10 is connected to the anode of the first infrared emitting diode LED6 and one end of the fourth resistor R50, respectively. The fifth pin of the second chip U10 is connected to the other end of the fourth resistor R50, the other end of the third capacitor C52, the cathode of the Schottky diode U9, and one end of the second capacitor C53, respectively. The fifth pin of the second chip U10 is connected to a DC power supply, and the second pin of the second chip U10 and the other end of the second capacitor C53 are both grounded. The third pin of the second chip U10 is connected to the AI ​​chip control circuit 110.

[0096] In some embodiments, when the AI ​​chip control circuit 110 receives the light intensity signal sent by the light sensing circuit 210 and determines that the ambient light intensity is lower than a preset threshold, it sends a supplementary light control signal to the infrared supplementary light circuit 220. After receiving the supplementary light control signal, the first pin of the second chip U10 controls its internal circuit to work, thereby driving components such as the Schottky diode U9 and the first inductor L6. The Schottky diode U9, as a fast switching element, can quickly turn on or off after receiving the control signal, thereby realizing the rapid on or off of the infrared supplementary light; the first inductor L6 acts as... The components smooth the current, reducing the impact of sudden current changes on the infrared fill light circuit 220 and protecting the first infrared emitting diode LED6 and the second infrared emitting diode LED7 from damage. At the same time, the third capacitor C52 and the fourth resistor R50 also play a role in filtering and current limiting, ensuring the stability and safety of the circuit. When the infrared fill light is turned on, the first infrared emitting diode LED6 and the second infrared emitting diode LED7 will emit infrared light waves that are invisible to the human eye. These infrared light waves can penetrate the night or low light environment, be captured by the camera and converted into a clear shooting signal.

[0097] In this embodiment, the infrared fill light circuit 220, including components such as a second capacitor C53, a third capacitor C52, a fourth resistor R50, a Schottky diode U9, a first infrared emitting diode LED6, a second infrared emitting diode LED7, a first inductor L6, and a second chip U10, ensures that the AI ​​human detection device maintains a high level of detection performance even in low-light environments. It also improves the accuracy of human detection, reduces false triggering or missed triggering due to insufficient light, thereby enhancing product reliability and user experience. Furthermore, it does not significantly affect the surrounding environment, enabling effective human detection without impacting personnel activities or the work environment.

[0098] Furthermore, by designing the infrared fill light circuit 220 and carefully selecting components and connection methods, this application achieves a compact structure, a moderate number of components, and a reasonable layout for the infrared fill light circuit 220. This design not only improves the reliability and stability of the infrared fill light circuit 220 but also facilitates integration with other circuit modules, thereby reducing production costs and providing users with a more cost-effective product option.

[0099] based on Figure 1 Please see Figure 5 This is a schematic diagram of an AI human detection device in an embodiment of this application. Figure 3 The device also includes an infrared receiving circuit 510.

[0100] The infrared receiving circuit 510 is connected to the AI ​​chip control circuit 110.

[0101] In one feasible implementation, the infrared receiving circuit 510 is used to acquire infrared signals based on the user's infrared remote control transmission, and demodulate the infrared signals to obtain baseband signals; the AI ​​chip control circuit 110 is used to receive the baseband signals, and restore the baseband signals to obtain action command signals, which are used to control other circuits in the AI ​​human detection device.

[0102] In some embodiments, other circuits in the AI ​​human detection device include, but are not limited to, steering circuits, switching circuits, lighting circuits, etc.

[0103] In some embodiments, based on the user's infrared remote control, the emitted infrared signal propagates through the air and is received by the infrared receiving circuit 510 to obtain the infrared signal.

[0104] In this embodiment of the application, by introducing an infrared receiving circuit 510 into the AI ​​human detection device, the function of receiving and processing infrared signals is realized, thereby providing users with a more convenient and flexible control method.

[0105] Furthermore, the infrared remote control method provided in this application avoids some safety risks, especially in industrial environments with high pressure, high temperature, or potential hazards. By using an infrared remote control for short-range control, users can maintain a safe distance from the device and ensure safety during operation.

[0106] based on Figure 1 Please see Figure 6 This is a schematic diagram of an AI human detection device in an embodiment of this application. Figure 4 The device also includes a wireless communication circuit 610.

[0107] The wireless communication circuit 610 is connected to the AI ​​chip control circuit 110.

[0108] In one feasible implementation, the wireless communication circuit 610 is used to acquire and receive wireless communication signals based on remote control by the user at the terminal; the AI ​​chip control circuit 110 is used to receive the wireless communication signals and determine the remote control signals based on the received wireless communication signals. The remote control signals are used to control other circuits in the AI ​​human detection device, or to determine the transmitting wireless communication signals based on the received wireless communication signals; the wireless communication circuit 610 is used to receive the transmitting wireless communication signals and send the transmitting wireless communication signals to the terminal.

[0109] In some embodiments, the terminal may be a computer, tablet, mobile phone, server, etc., and there is no limitation here.

[0110] In this embodiment of the application, by introducing a wireless communication circuit 610 into the AI ​​human detection device, a highly efficient remote control function is realized, which allows users to remotely control the device from a location far away from it, improving the convenience and flexibility of operation. This function is particularly important in scenarios where it is difficult to access or where remote monitoring is required.

[0111] based on Figure 6 Please see Figure 7 This is a schematic diagram of an AI human detection device in an embodiment of this application. Figure 5 The device also includes a DC power supply, which is a power supply protection circuit 710. The power supply protection circuit 710 includes a conversion module 711, a control power supply protection module 712, and a communication power supply protection module 713 connected in sequence.

[0112] Among them, the control power supply protection module 712 is connected to the AI ​​chip control circuit 110, and the communication power supply protection module 713 is connected to the wireless communication circuit 610.

[0113] In one feasible implementation, the conversion module 711 is used to convert AC mains power into a first DC power; the control power supply protection module 712 is used to receive the first DC power, convert the first DC power into a second DC power, and perform filtering and overvoltage protection processing on the second DC power to obtain a third DC power, which is used to power the AI ​​chip control circuit 110; the communication power supply protection module 713 is used to receive the second DC power, and perform filtering and overvoltage protection processing on the second DC power to obtain a fourth DC power, which is used to power the wireless communication circuit 610.

[0114] Among them, filtering refers to filtering out high-frequency noise and low-frequency interference in DC power; overvoltage protection refers to clamping the DC voltage to a safe level when a transient high voltage occurs.

[0115] It should be noted that filtering can effectively improve the quality of DC power, and overvoltage protection can protect some circuits in the AI ​​human detection device (such as the AI ​​chip control circuit 110 and the wireless communication circuit 610) from damage by transient overvoltage.

[0116] Furthermore, this application designs a power supply protection module 712 and a communication power supply protection module 713 to provide power to the AI ​​chip control circuit 110 and the wireless communication circuit 610, respectively. Since the wireless communication circuit 610 is powered separately and further filtered and overvoltage protected, the power supply of other circuits in the AI ​​human detection device can be avoided, thereby meeting the requirements of communication reliability, stability, and low power consumption continuity of the AI ​​human detection device.

[0117] In some embodiments, the control power supply protection module 712 may also use a third DC power supply to power other circuits in the AI ​​human detection device (such as the light sensing circuit 210, the infrared receiving circuit 510, etc.).

[0118] In some embodiments, when the AC mains voltage is 220V, the first DC voltage is 5V, and the second, third, and fourth DC voltages are all 3.3V.

[0119] In this embodiment, by introducing a power supply protection circuit 710 into the AI ​​human detection device, the power supply protection circuit 710 includes a conversion module 711, a control power supply protection module 712, and a communication power supply protection module 713 connected in sequence. Through precise power control and filtering technology, not only is the power supply quality of the AI ​​human detection device effectively improved, but the failure rate is also significantly reduced, enhancing its safety and reliability. This ensures the stability of communication and the continuity of low-power control in industrial scenarios, thereby effectively solving the power management problem faced by existing AI human detection devices in industrial applications.

[0120] based on Figure 7 Please see Figure 8 This is a schematic diagram of an AI human detection device in an embodiment of this application. Figure 6 The AI ​​chip control circuit 110 is connected to the communication power supply protection module 713.

[0121] In one feasible implementation, when the AI ​​chip control circuit 110 detects an abnormal fault in the wireless communication circuit 610, the AI ​​chip control circuit 110 generates an abnormal fault control signal; the communication power supply protection module 713 receives the abnormal fault control signal and stops supplying power to the wireless communication circuit 610 according to the abnormal fault control signal.

[0122] In some embodiments, the AI ​​chip control circuit 110 can detect whether the wireless communication circuit 610 has an abnormal fault. In the event of an abnormal fault in the wireless communication circuit 610, the AI ​​chip control circuit 110 generates and outputs an abnormal fault control signal, so that the communication power supply protection module 713 receives the abnormal fault control signal and stops supplying power to the wireless communication circuit 610 according to the abnormal fault control signal.

[0123] In other embodiments, the AI ​​chip control circuit 110 and other circuits in the AI ​​human detection device can assist in detecting whether the wireless communication circuit 610 has an abnormal fault. In the event of an abnormal fault in the wireless communication circuit 610, the AI ​​chip control circuit 110 generates and outputs an abnormal fault control signal, so that the communication power supply protection module 713 receives the abnormal fault control signal and stops supplying power to the wireless communication circuit 610 according to the abnormal fault control signal.

[0124] In this embodiment, when an abnormal fault occurs in the wireless communication circuit 610, the AI ​​chip control circuit 110 can quickly detect and generate an abnormal fault control signal. After receiving the abnormal fault control signal, the communication power supply protection module 713 immediately stops supplying power to the wireless communication circuit 610, thereby effectively preventing safety problems such as short circuits and overheating that may be caused by the continued operation of the faulty wireless communication circuit 610. This significantly improves the safety of the entire AI human detection device. Furthermore, by promptly cutting off the power supply to the faulty wireless communication circuit 610, the fault can be effectively prevented from spreading from the wireless communication circuit 610 to other circuits of the AI ​​human detection device, avoiding system-level failures. This helps maintain the overall stability and reliability of the system and reduces downtime and maintenance costs caused by faults.

[0125] Furthermore, by directly connecting the AI ​​chip control circuit 110 and the communication power supply protection module 713, this application achieves rapid transmission and response of abnormal fault control signals, which greatly shortens the time from abnormal fault detection to taking measures and improves fault response speed.

[0126] based on Figure 7 Please see Figure 9 This is a schematic diagram of an AI human detection device in an embodiment of this application. Figure 7 The device also includes a relay circuit 910.

[0127] The relay circuit 910 is connected to the AI ​​chip control circuit 110 and the conversion module 711, respectively.

[0128] In one feasible implementation, the AI ​​chip control circuit 110 is used to receive signals from other circuits in the AI ​​human detection device and generate a lighting control signal; the relay circuit 910 is used to receive the lighting control signal and control the switching module 711 to be turned on or off according to the lighting control signal.

[0129] In some embodiments, other circuits in the AI ​​human detection device include, but are not limited to, lighting circuits, infrared receiving circuits 510, wireless communication circuits 610, etc.

[0130] In some embodiments, the lighting control signal includes an on lighting control signal and an off lighting control signal. When the lighting control signal is an on lighting control signal, the relay circuit 910 controls the conversion module 711 to turn on the lighting; when the lighting control signal is an off lighting control signal, the relay circuit 910 controls the conversion module 711 to turn off the lighting.

[0131] In this embodiment, by introducing a relay circuit 910 into the AI ​​human detection device, precise control of peripheral circuits such as lighting is achieved, enabling users to conveniently control peripheral circuits such as lighting as needed, thus improving the user experience. At the same time, since the relay circuit 910 has the ability of electrical isolation and load control, it can effectively protect the AI ​​chip control circuit 110 and other circuits from electrical interference or damage that may be caused by peripheral circuits, thereby improving the reliability and safety of the entire device.

[0132] based on Figure 9 Please see Figure 10 The diagram below is a schematic of a relay circuit in an embodiment of this application. The relay circuit 910 includes a fifth resistor R9, a sixth resistor R13, a seventh resistor R15, an eighth resistor R16, a ninth resistor R18, a first diode D1, a second diode D2, a first transistor Q1, a second transistor Q2, and a relay K1.

[0133] In one feasible implementation, the first pin of relay K1 is connected to the anode of the second diode D2, one end of the eighth resistor R16, and the collector of the second transistor Q2. The base of the second transistor Q2 is connected to one end of the ninth resistor R18. The fourth pin of relay K1 is connected to the anode of the first diode D1, one end of the sixth resistor R13, and the collector of the first transistor Q1. The base of the first transistor Q1 is connected to one end of the fifth resistor R9. The fifth pin of relay K1 is connected to one end of the seventh resistor R15. The other end of the seventh resistor R15 is connected to the other end of the sixth resistor R13, the cathode of the first diode D1, the cathode of the second diode D2, and the other end of the eighth resistor R16. The emitters of the first transistor Q1 and the second transistor Q2 are both grounded. The other ends of the fifth resistor R9 and the sixth resistor R13 are both connected to the AI ​​chip control circuit 110. The second and third pins of relay K1 are both connected to the conversion module 711.

[0134] In some embodiments, the AI ​​chip control circuit 110 receives signals from other circuits in the AI ​​human detection device (such as infrared signals from the infrared receiving circuit 510, remote control signals from the wireless communication circuit 610, etc.), and generates corresponding lighting control signals based on these signals. The lighting control signals are input to the bases of the first transistor Q1 and the second transistor Q2 via the fifth resistor R9 and the sixth resistor R13, respectively. When the lighting control signal is high, the corresponding transistor is turned on, causing the coil of relay K1 to receive current excitation, thereby closing the relay K1 contacts. Conversely, when the lighting control signal is low, the corresponding transistor is turned off, the relay K1 coil is de-energized, and the contacts open. The contacts of relay K1 are connected to the conversion module 711 to control the power supply of external devices (such as lighting fixtures). When the contacts of relay K1 are closed, the conversion module 711 converts the mains power into voltage and current suitable for the external devices, thereby turning on the external devices. When the contacts of relay K1 are open, the external devices are powered off. The first diode D1 and the second diode D2 in the relay circuit 910 play a reverse cutoff role to prevent the reverse current from damaging the circuit. At the same time, relay K1 itself also has a certain electrical isolation function, which can isolate the electrical connection between the AI ​​chip control circuit 110 and the external device circuit, thereby protecting the AI ​​chip control circuit 110 from interference and damage from the external circuit.

[0135] In this embodiment, the designed relay circuit 910 includes components such as a fifth resistor R9, a sixth resistor R13, a seventh resistor R15, an eighth resistor R16, a ninth resistor R18, a first diode D1, a second diode D2, a first transistor Q1, a second transistor Q2, and a relay K1. This relay circuit 910 can achieve precise control of external devices (such as lighting fixtures); and can effectively isolate the AI ​​chip control circuit 110 from the external device circuit. This not only prevents the external device circuit from causing electrical interference to the AI ​​chip control circuit 110, but also protects the AI ​​chip control circuit 110 from potential damage from the external circuit, improving the reliability and safety of the entire device; and enables on-demand power supply to external devices, avoiding unnecessary energy waste.

[0136] Furthermore, by designing the relay circuit 910 and carefully selecting components and connection methods, this application achieves a compact structure, a moderate number of components, and a reasonable layout for the relay circuit 910. This design not only improves the reliability and stability of the relay circuit 910 but also facilitates integration with other circuit modules, thereby reducing production costs and providing users with a more cost-effective product option.

[0137] based on Figure 8 Please see Figure 11 The diagram below is a schematic of the communication power supply protection module in this application embodiment. The communication power supply protection module 713 includes a fourth capacitor C36, a fifth capacitor C38, a sixth capacitor C12, a seventh capacitor C13, a first ferrite bead LZ2, a first bidirectional transient suppression diode D5, a tenth resistor R6, an eleventh resistor R7, and a third chip U4.

[0138] In one feasible implementation, the first pin of the third chip U4 is connected to one end of the sixth capacitor C12; the third pin of the third chip U4 is connected to one end of the tenth resistor R6; the fourth pin of the third chip U4 is connected to one end of the eleventh resistor R7; the fifth pin of the third chip U4 is connected to one end of the seventh capacitor C13, one end of the first ferrite bead LZ2, one end of the first bidirectional transient suppression diode D5, and one end of the fifth capacitor C38; the other end of the fifth capacitor C38 is connected to the other end of the first bidirectional transient suppression diode D5; and the other end of the first ferrite bead LZ2 is connected to one end of the fourth capacitor C36. The second pin of the third chip U4, the other end of the fourth capacitor C36, the other end of the fifth capacitor C38, the other end of the sixth capacitor C12, the other end of the seventh capacitor C13, and the other end of the tenth resistor R6 are all grounded. One end of the fourth capacitor C36 is connected to the control power supply protection module 712. The first pin of the third chip U4 is used to connect to the wireless communication circuit 610, and the other end of the eleventh resistor R7 is used to connect to the AI ​​chip control circuit 110.

[0139] Among them, the bidirectional transient suppression diode is also called a TVS diode.

[0140] In some embodiments, when the second DC power supplied by the control power supply protection module 712 enters the communication power supply protection module 713 through the fourth capacitor C36, the fourth capacitor C36 acts as a preliminary filter, filtering out high-frequency noise in the DC power; the DC power passes through the first ferrite bead LZ2, which can further filter out low-frequency interference; the first bidirectional transient suppression diode D5 is connected in parallel across the fifth capacitor C38, and when a transient high voltage occurs in the DC power, the first bidirectional transient suppression diode D5 will quickly conduct, clamping the voltage to a safe level and protecting the subsequent circuits (such as the wireless communication circuit 610) from damage; when the AI ​​chip When the chip control circuit 110 detects an abnormal fault in the wireless communication circuit 610, the AI ​​chip control circuit 110 sends an abnormal fault control signal to the fourth pin of the third chip U4 of the communication power supply protection module 713 through the eleventh resistor R7. After receiving the abnormal fault control signal, the third chip U4 controls the output of the first pin through its internal logic, thereby cutting off the power supply to the wireless communication circuit 610. The sixth capacitor C12 and the seventh capacitor C13 are used to further filter out noise at the input and output terminals of the third chip U4. The tenth resistor R6 and the eleventh resistor R7 act as current-limiting resistors to protect the third chip U4 from current surges.

[0141] In this embodiment, a carefully designed communication power supply protection module 713, including components such as a fourth capacitor C36, a fifth capacitor C38, a sixth capacitor C12, a seventh capacitor C13, a first ferrite bead LZ2, a first bidirectional transient suppression diode D5, a tenth resistor R6, an eleventh resistor R7, and a third chip U4, effectively filters out high-frequency noise and low-frequency interference in DC power, improving power quality. It can also quickly clamp the voltage to a safe level when a transient high voltage occurs in DC power, protecting the wireless communication circuit 610 from overvoltage damage, thereby enhancing the stability and reliability of the entire AI human detection device. Furthermore, when an abnormal fault occurs in the wireless communication circuit 610, the AI ​​chip control circuit 110 quickly detects and sends an abnormal fault control signal to immediately control the communication power supply protection module 713 to stop supplying power to the wireless communication circuit 610, thereby quickly cutting off the fault source, preventing fault propagation, and improving fault response speed.

[0142] In addition, by designing a communication power supply protection module 713 and carefully selecting components and connection methods, this application achieves efficient power management and fault protection for the wireless communication circuit 610, significantly improving the stability and reliability of the AI ​​human detection device in industrial application scenarios.

[0143] based on Figure 11 Please see Figure 12 The diagram below is a schematic of the power supply protection module in this embodiment of the application. The power supply protection module 712 includes a third diode D6, an eighth capacitor C39, a ninth capacitor C40, a tenth capacitor C37, a second ferrite bead LZ3, a second bidirectional transient suppression diode D4, and a fourth chip U6.

[0144] In one feasible implementation, the second pin of the fourth chip U6 is connected to one end of the ninth capacitor C40 and one end of the second ferrite bead LZ3, respectively. The third pin of the fourth chip U6 is connected to the cathode of the third diode D6 and one end of the eighth capacitor C39, respectively. The other end of the eighth capacitor C39 is connected to one end of the second bidirectional transient suppression diode D4 and one end of the tenth capacitor C37, respectively. The other end of the tenth capacitor C37 is connected to the other end of the second bidirectional transient suppression diode D4 and the other end of the second ferrite bead LZ3, respectively.

The anode of the third diode D6 is connected to the conversion module 711. The second pin of the fourth chip U6 is connected to one end of the fourth capacitor C36. The other end of the second ferrite bead LZ3 is used to connect to the AI ​​chip control circuit 110.

[0145] In some embodiments, after the conversion module 711 converts AC mains power into first DC power, the first DC power enters the control power supply protection module 712 through the third diode D6. The third diode D6 acts as a rectifier to ensure unidirectional flow of DC power. The DC power then passes through the second ferrite bead LZ3, which filters out low-frequency interference and improves the quality of the DC power. The DC power then enters the third pin of the fourth chip U6. The fourth chip U6, as a power management chip, regulates and stabilizes the DC power output through its internal logic control. When a transient high voltage occurs in the DC power, the second bidirectional transient suppression diode D4 will quickly conduct to clamp the voltage to a safe level. This protects the AI ​​chip control circuit 110 from overvoltage damage. The eighth capacitor C39, the ninth capacitor C40, and the tenth capacitor C37 act as filters in the control power supply protection module 712, further reducing high-frequency noise and low-frequency interference in the DC power. The DC power, after being regulated and stabilized by the fourth chip U6, is output through the second pin of the fourth chip U6. This output is connected to one end of the fourth capacitor C36 to provide a second DC power to the communication power supply protection module 713. At the same time, this output is also connected to the AI ​​chip control circuit 110 through the other end of the second ferrite bead LZ3, providing a high-quality third DC power supply to the AI ​​chip control circuit 110.

It can also quickly conduct when a transient high voltage occurs in the DC power supply, clamping the voltage to a safe level, thereby protecting the AI ​​chip control circuit 110 from overvoltage damage and enhancing the stability and reliability of the entire AI human detection device. Furthermore, it improves the stability and filtering effect of the DC power supply, providing a high-quality power supply to the AI ​​chip control circuit 110 and reducing the impact of DC power fluctuations on the AI ​​chip control circuit 110.

[0147] In addition, by designing a power supply protection module 712 and carefully selecting components and connection methods, this application achieves efficient power management and fault protection for the AI ​​chip control circuit 110, significantly improving the stability and reliability of the AI ​​human detection device in industrial application scenarios.

[0151] Among them, step-down conversion refers to converting high-voltage DC power into low-voltage DC power.

[0152] In some embodiments, the DC-DC conversion module 7112 also uses a fifth DC power supply to power other circuits in the AI ​​human detection device.

[0153] In some embodiments, when the AC mains voltage is 220V, the first DC voltage is 5V, and the second, third, and fourth DC voltages are all 3.3V, the fifth DC voltage is 12V.
