[0006] In order to improve the reliability of monitoring of IoT devices, the utility model provides an IoT smart device that can self-monitor the operating status.

[0007] The present invention provides an IoT intelligent device capable of self-monitoring operating status, which adopts the following technical solutions:

[0008] An IoT smart device capable of self-monitoring its operating status comprises: a substrate, a central processing unit, a working circuit, a power supply module, a signal receiving module, a signal transmitting module, and a storage module, wherein the central processing unit, the working circuit, the power supply module, the signal receiving module, the signal transmitting module, and the storage module are all disposed on the substrate, and the working circuit, the power supply module, the signal receiving module, the signal transmitting module, and the storage module are all electrically connected to the central processing unit.

[0009] It also includes a circuit detection module and an intelligent diagnosis module, and the circuit detection module includes:

[0010] a first current sensor, mounted on a circuit connecting the power supply module and the central processing unit, for detecting a current between the power supply module and the central processing unit;

[0011] a second current sensor, mounted on a circuit connecting the central processing unit and the working circuit, for detecting a current between the working circuit and the central processing unit;

[0012] The intelligent diagnosis module includes:

[0013] a data processor, mounted on the substrate and electrically connected to the central processing unit, the first current sensor, and the second current sensor;

[0014] The indicating module is mounted on the substrate and is electrically connected to the data processor for displaying diagnostic information.

[0015] By adopting this technical solution, when current flows from the power supply module to the central processing unit (CPU), the first current sensor monitors the current flowing from the power supply module to the CPU and collects the current data from the power supply module to the CPU. When current flows from the CPU to the working circuit, the second current sensor detects the current flowing from the CPU to the working circuit and collects the current data from the CPU to the working circuit. The data processor in the intelligent diagnostic module calculates and analyzes the current data from the power supply module to the CPU and the current data from the CPU to the working circuit. When the intelligent diagnostic module detects that the current data from the power supply module to the CPU or the current data from the CPU to the working circuit fluctuates significantly or exceeds a set range, it determines that a circuit fault has occurred and displays the circuit fault information through the indicator module. In this way, by setting up an intelligent diagnostic module on the IoT device to monitor current changes, abnormal conditions such as overcurrent, short circuit, or load mutation can be detected in a timely manner, thereby improving the reliability and stability of the device. At the same time, the control strategies of the power supply module and the CPU can be optimized and repaired based on the current data to improve energy efficiency and extend the life of the device.

[0016] Optionally, the circuit detection module further includes:

[0017] A first voltage sensor is installed between the power supply module and the central processing unit, and is used to detect the output voltage of the power supply module and is electrically connected to the data processor;

[0018] The second voltage sensor is installed between the central processing unit and the working circuit, is used to detect the load voltage of the working circuit and is electrically connected to the data processor.

[0019] By adopting this technical solution, the first voltage sensor can monitor the output voltage of the power supply module in real time, and the second voltage sensor can monitor the load voltage of the working circuit in real time. After the first and second voltage sensors are connected to the data processor, the data processor can analyze the power supply voltage and load voltage data respectively. In this way, by monitoring voltage changes, abnormal conditions such as overvoltage and undervoltage can be detected in a timely manner, further improving the reliability of the device.

[0020] Optionally, the intelligent diagnosis module further includes:

[0021] A first circuit breaker is installed on the circuit connecting the power supply module and the central processing unit, and is used to control the on-off of the circuit between the power supply module and the central processing unit;

[0022] The second circuit breaker is installed on the circuit connecting the central processing unit and the working circuit, and is used to control the on-off of the circuit between the central processing unit and the working circuit.

[0023] By adopting this technical solution, when the data processor detects that the current or voltage detected by the first current sensor or the first voltage sensor has a large fluctuation or exceeds the set threshold, it proves that the current or voltage between the power supply module and the central processing unit is abnormal. At this time, the first circuit breaker can cut off the circuit between the power supply module and the central processing unit; when the data processor detects that the current or voltage detected by the second current sensor or the second voltage sensor has a large fluctuation or exceeds the set threshold, it proves that the current or voltage between the central processing unit and the working circuit is abnormal. At this time, the second circuit breaker can cut off the circuit between the central processing unit and the working circuit. In this way, the setting of the first circuit breaker and the second circuit breaker can cut off the abnormal power supply in time, prevent the entire system from crashing due to a single fault, reduce the probability of serious damage to the device, and improve the reliability and safety of the device.

[0024] Optionally, a physical detection module is further provided on the substrate, and the physical detection module includes:

[0025] a vibration sensor, mounted on the substrate and electrically connected to the data processor, for detecting a vibration signal of the substrate;

[0026] a temperature sensor, mounted on the substrate and electrically connected to the data processor, for detecting ambient temperature;

[0027] A position sensor is mounted on the substrate and electrically connected to the data processor for detecting position information of a movable component on the substrate.

[0028] By adopting this technical solution, the vibration sensor can record the vibration information when the substrate collides with an external object. The vibration information is analyzed by the data processor. If the vibration information exceeds the set value, it indicates that the collision may cause a fault. The position sensor detects the position information of the movable components installed on the substrate, such as the installation position information of the IoT card and the position information of the data connection port, to see whether the installation position of the movable components is offset during the collision and vibration, rendering the IoT device unusable. The temperature sensor can record the ambient temperature of the IoT device during operation. If the data processor detects that the data detected by the temperature sensor exceeds the set threshold, it indicates that timely cooling is required, otherwise a fault may occur. In this way, multiple sensors can monitor the operating status and environmental conditions of the device in real time, helping to understand the physical state and working environment of the IoT smart device, promptly detect the impact of external factors on the IoT smart device and take preventive measures, reduce the probability of device failure, and improve the reliability of the device.

[0029] Optionally, a third current sensor and a third voltage sensor are further provided between the physical detection module and the data processor, the third current sensor is used to detect the working current of the physical detection module, and the third voltage sensor is used to detect the load voltage of the physical detection module.

[0030] By adopting this technical solution, the sensor may be affected by environmental factors (such as temperature, humidity, vibration, etc.) during long-term operation and may malfunction or degrade in performance. The accuracy of its data directly affects the decision-making and control effects of the system. The third current sensor can detect the current information of the physical detection module, and the third voltage sensor can detect the voltage information of the physical detection module. By detecting the sensors in the physical detection module, the accuracy of the data detected by the physical detection module can be ensured.

[0031] Optionally, a received signal strength indicator is further provided between the signal receiving module and the central processing unit. The received signal strength indicator is electrically connected to the data processor and is used to detect the strength of the signal received by the signal receiving module.

[0032] With this technical solution, the wireless signal received by the data receiving module is first amplified and filtered. The analog signal is then converted to a digital signal via an analog-to-digital converter. The digital signal processor then processes the digital signal to extract characteristic parameters. Based on these extracted signal characteristics, the digital signal processor calculates the power level of the received signal and transmits this power level to the data processor in the intelligent diagnostic module via a data line. This allows the received signal strength to be measured by the received signal strength indicator, which helps determine whether the signal is caused by hardware failure or poor network signal strength, improving fault identification efficiency.

[0033] Optionally, the indication module includes an indicator light and a buzzer, the indicator light and the buzzer are both fixedly mounted on the substrate, and the indicator light and the buzzer are both electrically connected to the data processor.

[0034] By adopting this technical solution, when the data processor of the intelligent diagnostic module detects a fault, the color of the indicator light will change. The user can understand whether the working status of the equipment is normal based on the signal change of the indicator light. For example, the green indicator light usually indicates that the system is operating normally, while the red indicator light indicates that there is a fault or abnormality. When the intelligent diagnostic module detects a system abnormality, the data controller will sound an alarm with a buzzer to remind the user to perform maintenance or take other measures, thereby improving the convenience and safety of the device.

[0035] Optionally, the intelligent diagnosis module includes a diagnosis data storage module, and the diagnosis data storage module is electrically connected to the data processor.

[0036] By adopting this technical solution, the intelligent storage module can record various types of fault information that occur during equipment operation, including the time, type, severity, and maintenance time of the fault, which helps users analyze and troubleshoot faults, and then optimize and adjust the device to improve its reliability.

[0037] In summary, the present invention has at least one of the following beneficial technical effects:

[0038] 1. By setting up an intelligent diagnostic module on the IoT device to monitor changes in current and voltage, conditions such as overcurrent, overvoltage, short circuit or load undervoltage can be detected in a timely manner. The intelligent diagnostic module can also diagnose and analyze current information to detect circuit faults in a timely manner, thereby improving the reliability and stability of the device.

[0039] 2. By setting up a physical detection module on the substrate of the IoT smart device and using multiple sensors to detect the physical information of the IoT smart device, such as collision information, temperature information and the position information of active components, the impact of external factors on the IoT smart device can be discovered in a timely manner and prevented, thereby reducing the probability of device failure and further improving the reliability of the device.

[0040] 3. A received signal strength indicator is set between the data receiving module and the central processing unit. The received signal strength indicator can measure the received signal strength and help determine whether the signal is caused by hardware failure or poor network signal strength based on the signal strength.

[0044] The present invention discloses an IoT smart device that can self-monitor its operating status. Figure 1, an Internet of Things smart device capable of self-monitoring its operating status, comprising a substrate 1, a central processing unit 2 mounted on the substrate 1, a working circuit 3 connected to the central processing unit 2, a power supply module 4 for powering the device and the circuit, a signal receiving module 5 for receiving Internet of Things signals, a signal transmitting module 51 for transmitting information of the Internet of Things smart device to an Internet of Things terminal, a storage module 6 connected to the central processing unit 2, a circuit detection module 7 for monitoring circuit information of the Internet of Things smart device, an intelligent diagnosis module 8 for monitoring the operating status of the Internet of Things smart device, and a physical detection module 9 for monitoring the physical status of the Internet of Things smart device; during the operation of the Internet of Things smart device, the circuit detection module 7 and the physical detection module 9 will respectively detect the circuit part and the physical status of the Internet of Things smart device, and detect and analyze the detected circuit information and physical status information through the intelligent diagnosis module 8 mounted on the substrate 1, so as to timely discover potential problems of the Internet of Things smart device and improve the reliability and security of the Internet of Things smart device.

[0045] Reference Figure 1When the power supply module 4 supplies power to the central processing unit 2, the connection circuit between the power supply module 4 and the central processing unit 2 is sequentially connected with a first current sensor 71, a first voltage sensor 73 and a first circuit breaker 83, wherein the first current sensor 71 adopts a Hall current sensor, the first voltage sensor 73 adopts a Hall voltage sensor, and the first circuit breaker 83 adopts a relay. The Hall current sensor works based on the Hall effect principle and indirectly measures the current by detecting the magnetic field strength generated by the current. It measures by induction and does not need to be directly connected to the circuit. It has the ability of electrical isolation, so it can measure the current without interfering with the main circuit. At the same time, the Hall current sensor has the characteristics of high precision and fast response, and can promptly detect the occurrence of problems such as circuit overload or short circuit; the Hall voltage sensor can sense the magnetic field and generate a Hall voltage proportional to the magnetic field strength. In order to improve the measurement sensitivity of the Hall voltage sensor Degree, an amplification circuit is set for the Hall voltage sensor or a magnetic ring is equipped to concentrate and enhance the magnetic flux flowing through the Hall element, so as to achieve accurate measurement of the voltage between the power supply module 4 and the central processing unit 2; the relay controls the closing or opening of the contacts through electromagnetic force, thereby realizing the on-off control of the circuit, controlling the on-off of the circuit by controlling the large current with a small current, and providing electrical isolation to improve the safety of the system; the first current sensor 71, the first voltage sensor 73 and the first circuit breaker 83 are all electrically connected to the intelligent diagnosis module 8. When the intelligent diagnosis module 8 detects that the first current sensor 71 or the first voltage sensor 73 detects a large fluctuation in current or voltage, the intelligent diagnosis module 8 can control the first circuit breaker 83 to disconnect the circuit connection between the power supply module 4 and the central processing unit 2 according to the set fluctuation threshold, thereby reducing the probability of serious faults and improving the reliability and safety of the device.

[0046] Reference Figure 1 In the circuit between the central processing unit 2 and the working circuit 3, a second circuit breaker 84, a second voltage sensor 74, and a second current sensor 72 are connected in sequence. The second current sensor 72 adopts a Hall current sensor, the second voltage sensor 74 adopts a Hall voltage sensor, and the second circuit breaker 84 adopts a relay. The second current sensor 72, the second voltage sensor 74, and the second circuit breaker 84 are all electrically connected to the intelligent diagnostic module 8. The second voltage sensor 74 and the second current sensor 72 can monitor the current information and voltage information of the working circuit 3, and analyze the monitored current information and voltage information through the intelligent diagnostic module 8, and only disconnect the power supply of the working circuit 3 through the second circuit breaker 84, so that the intelligent diagnostic module 8, the physical detection module 9, the signal receiving module 5, the signal transmitting module 51 and the storage module 6 continue to work, which helps to help users find the fault point.

[0047] Reference Figure 1The physical detection module 9 includes a vibration sensor 91, a temperature sensor 92 and a position sensor 93, wherein the vibration sensor 91 and the temperature sensor 92 are fixedly mounted on the substrate 1, wherein the vibration sensor 91 adopts an inertial vibration sensor 91. When it is fixedly mounted on the substrate 1, the vibration sensor 91 can record the corresponding vibration information when the substrate 1 collides or falls, and send the vibration information to the intelligent diagnosis module 8. When the intelligent diagnosis module 8 determines that the vibration data exceeds the preset value, there may be a collision fault, such as the position of the Internet of Things card is offset, or the terminal is loose, etc. The temperature sensor 92 adopts a surface-mounted thermocouple temperature sensor 92. The temperature sensor 92 is installed near the modules that are easily affected by temperature, such as the central processor 2, battery or motor, etc. The operating temperature of the substrate 1 is monitored in real time, and the monitoring data is sent to the intelligent diagnostic module 8. When the intelligent diagnostic module 8 detects that the temperature is too high or too low, it will alert the user through the Internet of Things, reducing the adverse effects of excessive high or low temperatures on the Internet of Things smart device. The position sensor 93 is made of a pressure sensor made of strain gauges and connected to the intelligent diagnostic module 8. The position sensor 93 is installed near the structure of the active connection, such as in the Internet of Things card slot or at the connection of the wiring port. When the Internet of Things card falls off or becomes loose in the Internet of Things card slot, or when the wiring port is loose, the position sensor 93 in the Internet of Things card slot or at the wiring port will detect a pressure change. When the intelligent diagnostic module 8 detects that the pressure change of the position sensor 93 exceeds the set value, it indicates that the connection of the active structure is loose. By monitoring the working status of the substrate 1 through the physical detection module 9, the operating status of the Internet of Things smart device can be monitored at the physical level, and the adverse effects of external physical factors on the Internet of Things smart device can be promptly detected, further improving the reliability of the Internet of Things smart device.

[0048] Reference Figure 1A third current sensor 75 and a third voltage sensor 76 are also connected to the circuit connecting the physical detection module 9 and the intelligent diagnosis module 8. The third current sensor 75 and the third voltage sensor 76 are electrically connected to the intelligent diagnosis module 8. The third current sensor 75 adopts a Hall current sensor, and the third voltage sensor 76 adopts a Hall voltage sensor. The third current sensor 75 and the third voltage sensor 76 will detect the working current and working voltage of the physical detection module 9 and send the detection information to the intelligent diagnosis module 8. The intelligent diagnosis module 8 will analyze the working current and working voltage of the physical detection module 9 and then judge the working status of the physical detection module 9. When the intelligent diagnosis module 8 detects that the working current or working voltage of the physical detection module 9 has a large fluctuation, it indicates that the physical detection module 9 has a fault. At this time, the intelligent diagnosis module 8 will record the fault information and remind the user, thereby reducing the user's misjudgment of the physical status of the Internet of Things smart device based on the erroneous information of the physical detection module 9 and improving the reliability of the detection data of the physical detection module 9.

[0049] Reference Figure 1 A received signal strength indicator 53 is also connected to the circuit connecting the signal receiving module 5 and the central processor 2. The wireless signal received by the data receiving module is first amplified and filtered, and then the analog signal is converted into a digital signal through an analog-to-digital converter. The digital signal processor will send part of the signal to the central processor 2 for communication with the central processor 2, and the other part will be sent to the received signal strength indicator 53 to process the digital signal and extract the characteristic parameters of the signal. The received signal strength indicator calculates the power level of the received signal based on the extracted signal characteristic parameters, and transmits the received signal power level to the data processor 81 in the intelligent diagnosis module 8 through the data line. The intelligent diagnosis module 8 analyzes the signal power level. When the signal power level is lower than the set value, that is, the signal strength is too low, it may cause data transmission errors or losses, proving that the fault of the IoT smart device is caused by a network problem, and the user needs to optimize and adjust the network. The reliability of the IoT smart device can be improved by monitoring the network.

The data processor 81 corresponds to the first current sensor 71, the second current sensor 72, the third current sensor 75, the first voltage sensor 73, the second voltage sensor 74, the third voltage sensor 76, the received signal strength indicator 53, the vibration sensor 91, the temperature sensor 92 and the position sensor 93 respectively. 6. The received signal strength indicator 53, the vibration sensor 91, the temperature sensor 92 and the position sensor 93 are electrically connected. When the data processor 81 analyzes that the sensor data is abnormal, the data processor 81 will control the indicator light 821 connected to the abnormal sensor to light up, and control the buzzer 822 to sound an alarm at intervals to alert the user. At the same time, the data processor 81 will transfer the abnormal information to the diagnostic data storage module 85 for storage, and send the abnormal information to the user end through the Internet of Things through the central processor 2 and the signal transmission module 51 to remind the user; when the data processor 81 analyzes that the current or voltage of the power supply module 4 or the working circuit 3 is abnormal, the data processor 81 controls the corresponding first circuit breaker 83 or the second circuit breaker 84 to cut off the circuit connection, thereby reducing the probability of serious circuit failure and improving the safety of the Internet of Things device.

[0051] The implementation principle of an Internet of Things smart device capable of self-monitoring the operating status of the present utility model is as follows: when the power supply module 4 supplies power to the central processing unit 2, the first current sensor 71 and the first voltage sensor 73 detect the current and voltage of the power supply module 4, and the data processor 81 diagnoses and analyzes the detected data. When the detected data is abnormal, the circuit connection between the power supply module 4 and the central processing unit 2 is disconnected by the first circuit breaker 83; a second voltage sensor 74 and a second current sensor 72 are provided in the circuit connecting the central processing unit 2 and the working circuit 3 to detect the current and voltage of the working circuit 3, and the data processor 81 diagnoses and analyzes the detected data.

The circuit connection between the processor 2 and the working circuit 3; a vibration sensor 91, a temperature sensor 92 and a position sensor 93 are set on the substrate 1 of the Internet of Things smart device to detect the physical state of the Internet of Things smart device, and a third current sensor 75 and a third voltage sensor 76 are used to detect the working current and voltage of the vibration sensor 91, the temperature sensor 92 and the position sensor 93; a received signal strength indicator 53 is set on the circuit connecting the signal receiving module 5 and the central processor 2, which can detect the received network strength; the data analyzer in the intelligent diagnostic module 8 can analyze various detection data and prompt the user through the indicator light 821 and the Internet of Things to help the user better understand the working status of the Internet of Things smart device.

[0052] In summary, the present invention can monitor the operating status of the IoT smart device from three aspects: circuit status, physical status and network status of the IoT smart device by installing a circuit detection module 7, a physical detection module 9 and a received signal strength indicator 53 on the IoT smart device, and perform fault analysis through the intelligent diagnosis module 8 built in it, which can help users to timely discover circuit faults, physical faults or network faults, thereby improving the reliability of the device; by setting the first circuit breaker 83 and the second circuit breaker 84, the circuit connection can be cut off in time when a fault is detected, and when the user cannot discover and handle the fault in time, it plays an isolation role, isolating the faulty part from the healthy part, reducing the current damaging the circuit and causing equipment damage or safety accidents; the intelligent diagnosis module 8 and the indication module 82 equipped in it can remind the user through its own indicator light 821 and buzzer 822 when the network connection is not good, thereby improving the reliability of the IoT smart device.
