[0002] With the accelerating development of urbanization and the increasing integration of urban and rural areas, the extension of low-voltage distribution network cables is becoming more and more extensive, resulting in many distribution network lines being in a poor operating state. In particular, the problems of overhead conductors of old low-voltage distribution network lines are more prominent.
[0003] At present, old low-voltage distribution network lines usually adopt the fixing method of street codes and iron wire ties, which is easy to cause insulation damage. The installation forms of conductors and street codes include various types such as cross-line and corner. Among them, the outer layer of insulated conductors at the corner position is more susceptible to aging and cracking compared with the cross-line method. In this case, the hand-tying wire fixing method has a risk of electric leakage, especially in rainy days, which seriously threatens the lives of the people and constitutes a hidden danger to public safety related to electricity. Therefore, it is necessary to design a monitoring device with low cost, simple structure and easy installation to monitor the electric leakage of overhead conductors of old low-voltage distribution network lines.

[0059] The following will, with reference to the accompanying drawings, provide a detailed description of the anti-electric leakage high-temperature warning and monitoring device, method, and equipment provided in the embodiments of the present application through specific embodiments and their application scenarios.
[0060] The application scenario of the embodiments of the present application is to perform electric leakage monitoring on the device to be detected, and the above anti-electric leakage high-temperature warning and monitoring method is specifically executed by the anti-electric leakage high-temperature warning and monitoring device.
[0061] The anti-electric leakage high-temperature warning monitoring device includes: a main housing, and two monitoring connection points. The two monitoring connection points are connected to the monitoring module of the main housing through wires. The two monitoring connection points are connected to the device to be detected in an adhesive manner. The two monitoring connection points include an electric leakage monitoring connection point and a temperature monitoring connection point. The monitoring module is powered by a low-power battery and includes: an MCU unit, an electric leakage monitoring unit, a temperature monitoring unit, and a communication module, which are used to perform electric leakage monitoring and temperature monitoring on the device to be detected.
[0062] Among them, the main housing is a small-volume main housing, which serves as the housing of the entire monitoring device and is used to protect the internal electronic components and circuits. The two monitoring connection points are connected to the monitoring module inside the main housing through wires and are used to physically connect to the device to be detected for electric leakage and temperature monitoring. The electric leakage monitoring connection point is used to monitor the electric leakage situation of the device to be detected. The temperature monitoring connection point is used to monitor the temperature of the device to be detected to prevent the device from overheating. The monitoring module is the core part of the device and is powered by a low-power battery to ensure long-term stable operation.
[0063] The monitoring module includes the following units:
[0064] MCU unit (Microcontroller Unit): As the control center of the entire monitoring module, it is responsible for processing data, issuing instructions, etc.
[0065] Electric leakage monitoring unit: It is used to monitor the electric leakage situation of the device to be detected in real time. Once electric leakage is detected, it will immediately trigger an alarm.
[0066] Temperature monitoring unit: It is used to monitor the temperature of the device to be detected in real time. When the temperature exceeds the preset threshold, it will issue a high-temperature warning.
[0067] Communication module: It is used to transmit the monitored data (such as electric leakage situation, temperature data) to external devices or systems for further analysis and processing.
[0068] In one embodiment, first, the two monitoring connection points (electric leakage monitoring connection point and temperature monitoring connection point) are connected to the device to be detected in an adhesive manner. Then, the monitoring module starts to work, and the electric leakage monitoring unit and the temperature monitoring unit are used to monitor the electric leakage situation and temperature of the device to be detected in real time. The MCU unit is responsible for processing the monitored data and judging whether to trigger an alarm according to the preset threshold. If the electric leakage situation exceeds the preset threshold or the temperature exceeds the high-temperature threshold, the MCU unit will immediately send an alarm message through the communication module. The communication module transmits the alarm message to external devices or systems so that relevant personnel can timely understand the operating status of the device and take corresponding measures for processing.
[0069] Figure 1It is a schematic flow chart of a leakage prevention and high-temperature warning monitoring method provided by an embodiment of the present application. The leakage prevention and high-temperature warning monitoring method is applied to the above-mentioned leakage prevention and high-temperature warning monitoring device, such as Figure 1 shown, the method includes:
[0070] S101. The leakage monitoring unit obtains voltage data of the device to be detected based on the leakage monitoring connection point and sends it to the MCU unit.
[0071] Among them, the leakage monitoring unit is a device used to monitor whether an electrical device has a leakage. It usually judges whether there is a leakage situation by monitoring the current or voltage change of the electrical device. The leakage monitoring connection point refers to the connection point for monitoring voltage that is connected to the monitoring module of the main housing through a wire. Voltage data refers to the characteristic information such as the magnitude, direction, and waveform of the voltage in an electrical device or circuit, which is used to monitor and analyze the operating state of the electrical device. The MCU unit is the abbreviation of Microcontroller Unit, also known as Single Chip Microcomputer or microcontroller. It is a chip-level computer that appropriately reduces the frequency and specifications of the central processing unit (CPU) and integrates peripherals such as memory, counter (Timer), USB, A / D conversion, UART, PLC, DMA, and LCD drive circuit on a single chip.
[0072] In one embodiment, the leakage monitoring unit is connected to the leakage monitoring connection point of the device to be detected through a wire, and the leakage monitoring connection point is pasted at the position of the point to be measured of the device to be detected. After connection, the leakage monitoring unit samples the voltage of the device to be detected at the leakage monitoring connection point in real time or periodically through an internal voltage sensor. And an analog-to-digital converter (ADC) is used to convert the analog voltage signal into a digital signal, which is convenient for subsequent data processing and transmission. After the leakage monitoring unit obtains and processes the voltage data, it packs and sends the data to the MCU unit. For example, through the I2C protocol, the leakage monitoring unit is used as a slave device and the MCU unit is used as a master device. When the master device requests data or the slave device detects that the voltage data changes exceed a certain threshold, the slave device can send the voltage data to the master device. The present application does not limit the specific transmission method.
[0073] S102. The temperature monitoring unit obtains temperature data of the device to be detected based on the temperature monitoring connection point and sends it to the MCU unit.
[0074] Among them, the temperature monitoring unit refers to a device used to measure and monitor temperature, which can convert temperature changes into voltage signals and output digital or analog signals. The leakage monitoring connection point refers to the connection point for monitoring temperature that is connected to the monitoring module of the main housing through a wire. The temperature information refers to the temperature value detected by the temperature monitoring unit and the relevant information during the acquisition process of the temperature value.
[0075] In one embodiment, the temperature monitoring unit is connected to the temperature monitoring connection point of the device to be detected through a wire, and the temperature monitoring connection point is pasted at the position to be measured of the device to be detected. After connection, the temperature monitoring unit samples the voltage at the temperature monitoring connection point of the device to be detected in real time or periodically through an internal temperature sensor. And an analog-to-digital converter (ADC) is used to convert the analog temperature signal into a digital signal, and the processed temperature data is sent to the MCU unit.
[0076] S103. The MCU unit receives the voltage data and the temperature data, determines the voltage warning threshold and the temperature warning threshold based on a preset rule, and generates a warning message when the voltage data meets the voltage warning threshold and / or the temperature data meets the temperature warning threshold.
[0077] Among them, the preset rule refers to the corresponding conditions preset for determining the voltage warning threshold and the temperature warning threshold. The voltage warning threshold refers to a preset upper limit value of voltage in the power system to ensure the safe and stable operation of the equipment. When the actual voltage exceeds this threshold, the system will send a warning signal to remind the operator to take measures for adjustment in time. The temperature warning threshold refers to a preset upper limit value of temperature in the power system to prevent dangers or faults caused by excessive temperature. When the actual temperature reaches or exceeds this threshold, the temperature monitoring system will send a warning signal to remind the relevant personnel to pay attention and take corresponding measures. The warning message is a message with a warning function to inform in advance of the dangers and emergencies caused by equipment leakage.
[0078] In one embodiment, the MCU unit receives the voltage data transmitted by the leakage monitoring unit and the temperature data transmitted by the temperature detection unit through the I2C interface, and stores this data in internal registers or caches. The preset rules are stored in the internal Flash memory or external EEPROM of the MCU. These preset rules contain the specific values or ranges of the voltage warning threshold and temperature warning threshold set according to different device characteristics and application scenarios. The MCU unit reads these preset rules through program code, and assigns the corresponding voltage warning threshold and temperature warning threshold to internal variables for subsequent comparison and judgment. Then, the MCU unit uses comparison instructions to check whether the received voltage data meets the voltage warning threshold (such as the voltage being higher than the upper limit value), and whether the temperature data meets the temperature warning threshold (the temperature being higher than the upper limit value).
[0079] If the voltage data meets the voltage warning threshold, or the temperature data meets the temperature warning threshold, or both are satisfied at the same time, the MCU unit generates a warning message through program logic. The warning message can be a specific digital code (for example, using "1" to represent voltage warning, "2" to represent temperature warning, and "3" to represent both warnings), or it can be a text message containing details such as the warning type, current voltage value, and temperature value. This warning message can be stored in a specific buffer area inside the MCU, waiting to be further sent to the communication module.
[0080] Optionally, generating a warning message under the condition that the voltage data meets the voltage warning threshold and / or the temperature data meets the temperature warning threshold includes:
[0081] When the voltage data meets the voltage warning threshold and the temperature data does not meet the temperature warning threshold, a leakage warning message is generated;
[0082] When the voltage data does not meet the voltage warning threshold and the temperature data meets the temperature warning threshold, a temperature warning message is generated;
[0083] When the voltage data meets the voltage warning threshold and the temperature data meets the temperature warning threshold, a high-risk warning message is generated.
[0084] Among them, the leakage warning message refers to the warning message issued by the monitoring system when there is a leakage phenomenon in the electrical system or equipment. The temperature warning message refers to the warning message issued by the monitoring system when the temperature of the equipment or system exceeds the preset safe range. The high-risk warning message refers to the warning message including leakage warning, temperature warning, and any other warnings that may cause serious consequences. The high-risk warning message indicates that if no measures are taken immediately, serious equipment failures, safety accidents, or fires may occur.
[0085] In one embodiment, when the monitored voltage data reaches or exceeds the preset voltage warning threshold, and at the same time, the monitored temperature data does not reach the preset temperature warning threshold, the system will generate a leakage warning message at this time. This usually means that there may be a leakage phenomenon in the electrical system, and immediate inspection and repair are required.
[0086] When the monitored voltage data does not reach the preset voltage warning threshold, and at the same time, the monitored temperature data reaches or exceeds the preset temperature warning threshold, the system will generate a temperature warning message at this time. This indicates that the device or system may face the risk of damage or fire due to overheating, and immediate measures need to be taken to cool down or stop the machine for inspection.
[0087] When the monitored voltage data reaches or exceeds the preset voltage warning threshold, and at the same time, the monitored temperature data also reaches or exceeds the preset temperature warning threshold, the system will generate a high-risk warning message at this time. This indicates that the device or system faces the risks of both leakage and overheating at the same time, and the situation is very critical. Immediate emergency measures need to be taken for intervention to prevent accidents from occurring.
[0088] As can be seen from the above, the above warning mechanism helps to detect and respond to potential electrical safety hazards in a timely manner, ensuring the safety of equipment and personnel. In practical applications, these warning messages are usually conveyed to relevant personnel through means such as audible and visual alarms, text message notifications, and email reminders, so that they can make a quick response.
[0089] Optionally, the monitoring module further includes a load monitoring unit and an environment monitoring unit. Before determining the voltage warning threshold and temperature warning threshold based on preset rules, it further includes:
[0090] The load monitoring unit obtains the load information of the device to be detected and sends it to the MCU unit;
[0091] The environment monitoring unit obtains the ambient temperature information and sends it to the MCU unit;
[0092] The MCU unit receives the load information and the ambient temperature information.
[0093] Among them, the load monitoring unit refers to an intelligent module used to monitor the load-related parameters of the device to be measured. The environment monitoring unit refers to an intelligent module used to monitor the environmental parameters of the device to be measured. The ambient temperature information refers to the description of the air temperature situation around the device to be measured, which reflects the cold and hot degree of the environment where the device to be measured is located. The load information refers to the workload borne by the device to be measured or the power consumption, etc.
[0094] In one embodiment, the load monitoring unit obtains the load information of the device to be detected through sensors (such as current transformers, power sensors). The sensors convert physical quantities into electrical signals. For example, a current transformer generates an induced current proportional to the magnitude of the current passing through the wire. The load monitoring unit converts the analog electrical signals obtained by the sensors into digital signals through an internal analog-to-digital converter. Then, according to a pre-set communication protocol, the load information data is sent to the MCU unit. Taking the I2C protocol as an example, the load monitoring unit, as a slave device, sends data to the I2C bus at the request of the MCU unit (master device), and the MCU unit receives the data from the bus. Similarly, the environmental monitoring unit obtains the environmental temperature information using temperature sensors (such as thermistors, digital temperature sensors). The thermistor changes its own resistance value with the change of the environmental temperature, converts the resistance change into a voltage change through a supporting circuit, and then converts it into a digital signal by an analog-to-digital converter. Then, according to the selected communication protocol (such as the SPI protocol), the environmental monitoring unit sends the environmental temperature information to the MCU unit. Under the SPI protocol, the MCU unit receives the environmental temperature information from the environmental monitoring unit by controlling the clock signal and the data transmission direction. The communication interface controller inside the MCU unit decodes the received data according to the communication protocol used (I2C, SPI, UART, etc.). For example, when receiving data sent by the I2C protocol, the MCU unit reads the data bits on the data line in each clock cycle, combines these bits into bytes, and finally restores the load information or environmental temperature information and stores it in the internal register or memory unit for subsequent processing and analysis. The embodiments of the present application do not limit the specific data method, and the above transmission methods are only for illustrative purposes.
[0095] Optionally, the monitoring module further includes a timing monitoring unit. Before determining the voltage warning threshold and the temperature warning threshold based on the preset rules, it further includes:
[0096] The timing monitoring unit obtains the running duration of the device to be detected and sends it to the MCU unit;
[0097] The MCU unit determines the threshold adjustment factor based on the running duration.
[0098] Among them, the timing monitoring unit refers to an intelligent module for monitoring the running duration of the device to be detected. The running duration of the device to be detected refers to the usage duration of the device to be detected. The threshold adjustment factor is a numerical factor used to adjust the preset threshold.
[0099] In one embodiment, the timing monitoring unit continuously monitors the running time of the device to be detected, which is calculated from the start of device startup. When it is necessary to determine the voltage warning threshold and the temperature warning threshold, the timing monitoring unit obtains the current running duration and sends it to the MCU unit. After receiving the running duration, the MCU unit calculates a threshold adjustment factor according to a preset rule or algorithm. This factor is a numerical value used to adjust the preset voltage and temperature warning thresholds. Its value may change as the running duration increases to reflect that different warning thresholds may be required at different running stages of the device. By means of the adjustment factor, the system can more flexibly adapt to different running stages, thereby improving the accuracy and reliability of the warning.
[0100] Optionally, the MCU unit determines the threshold adjustment factor based on the running duration, including:
[0101] When the running duration is less than or equal to the first running duration, the threshold adjustment factor is the first adjustment factor;
[0102] When the running duration is greater than the first running duration and less than or equal to the second running duration, the threshold adjustment factor is the second adjustment factor;
[0103] When the running duration is greater than the second running duration, the threshold adjustment factor is the third adjustment factor, and the third adjustment factor is less than the second adjustment factor is less than the first adjustment factor is less than 1.
[0104] In one embodiment, when the running duration of the device is less than or equal to the first running duration, the threshold adjustment factor is set to the first adjustment factor. When the device has just started running or the running time is short, the warning threshold will be adjusted based on a relatively high adjustment factor to ensure the safe operation of the device in the initial stage and avoid triggering a warning due to minor fluctuations.
[0105] When the running duration of the device is greater than the first running duration and less than or equal to the second running duration, the threshold adjustment factor is set to the second adjustment factor. At this stage, the device has been running for some time but is still in a relatively stable running stage. Therefore, the warning threshold will be adjusted according to a relatively low (but higher than the third adjustment factor) adjustment factor to reflect the running state of the device at this stage.
[0106] When the running time of the device is greater than the second running time, the threshold adjustment factor is set to the third adjustment factor. This adjustment factor is the lowest among the three adjustment factors and is less than 1. This indicates that as the running time of the device increases, the device may become more sensitive or prone to failures due to factors such as wear and aging. Therefore, the warning threshold needs to be adjusted lower (compared to the previous two stages) in order to detect potential problems earlier and take corresponding measures.
[0107] The third adjustment factor is less than the second adjustment factor is less than the first adjustment factor and less than 1. This means that as the running time of the device increases, the adjustment factor gradually decreases, resulting in a gradual decrease in the warning threshold, so as to ensure that the warning threshold can accurately reflect the running state of the device and trigger a warning signal when necessary, thereby ensuring the safety and reliability of the device.
[0108] S104. Forward the warning information based on the communication module.
[0109] Among them, the communication module is an important part of the modern communication field, used to realize data transmission and communication connection between devices. It is a device integrating functions such as communication interfaces, modems, radio frequency circuits, and control logic, and can complete wireless or wired data transmission and communication between devices.
[0110] In one embodiment, the warning information is encapsulated into a data packet or message format that the communication module can recognize, a communication connection with the receiving device is established through the communication module, and the encapsulated warning information is sent to the receiving device through the communication module.
[0111] As can be seen from the above, the leakage monitoring unit obtains the voltage data of the device to be detected based on the leakage monitoring connection point and sends it to the MCU unit; the temperature monitoring unit obtains the temperature data of the device to be detected based on the temperature monitoring connection point and sends it to the MCU unit; the MCU unit receives the voltage data and the temperature data, determines the voltage warning threshold and the temperature warning threshold based on preset rules, generates warning information under the condition that the voltage data meets the voltage warning threshold and / or the temperature data meets the temperature warning threshold; and forwards the warning information based on the communication module. The above anti-leakage high-temperature warning monitoring method can solve the problem that the overhead conductors of low-voltage lines in old and aging distribution networks are prone to leakage risks and there are serious hidden dangers of electricity-related public safety, and can realize the leakage monitoring of the overhead conductors of low-voltage lines in old and aging distribution networks at low cost, easy installation and high efficiency.
[0112] Figure 2 It is a flowchart of a method for determining the voltage warning threshold and the temperature warning threshold based on preset rules provided by an embodiment of the present application. As Figure 2 shown, the method includes:
[0113] S201. Determine the load status based on the load information, determine the initial voltage threshold based on the load status, and determine the voltage warning threshold based on the initial voltage threshold.
[0114] Among them, the degree of work load that a device or system bears during operation. Usually, it can be evaluated by measuring parameters such as the current, voltage, and power of the device. The initial voltage threshold is a preset voltage boundary value.
[0115] In one embodiment, parameters such as the current, voltage, and power of the device are collected in real time through sensors or monitoring devices. The above parameters can reflect the actual working status and load degree of the device. Process and analyze the collected load information, such as calculating statistical quantities such as the average value, maximum value, and minimum value. According to the rated capacity and performance parameters of the device, evaluate whether the current load status is within the normal range. According to the analysis results, classify the load status into different levels such as light load, medium load, and heavy load. Determine the range of the initial voltage threshold corresponding to each load status. Determine the initial voltage threshold under the current load status, and determine the final voltage warning threshold according to the initial voltage threshold and other operating parameters of the device.
[0116] Optionally, the load information includes the load value and the rated load value. The determining the load status based on the load information and determining the initial voltage threshold based on the load status includes:
[0117] When the load value is less than or equal to 30% of the rated load value, determine that the load status is a low load status, and the initial voltage threshold is the first voltage threshold;
[0118] When the load value is greater than 30% of the rated load value and less than or equal to 70% of the rated load value, determine that the load status is a normal load status, and the initial voltage threshold is the second voltage threshold;
[0119] When the load value is greater than 70% of the rated load value, determine that the load status is a high load status, and the initial voltage threshold is the third voltage threshold, and the first voltage threshold is greater than the second voltage threshold is greater than the third voltage threshold.
[0120] Among them, the load value refers to the value of current, voltage, power, etc. accepted in an electrical system. The rated load value refers to the maximum load value determined at the design of a device or system and that can operate safely continuously.
[0121] In one embodiment, first, the load value needs to be obtained through the load monitoring unit. At the same time, the rated load value of the device to be detected is required. This rated load value can be a fixed parameter pre-stored in the storage unit of the device (such as the internal Flash of the MCU), or obtained through user input or an external configuration file. When the load value is less than or equal to 30% of the rated load value, it is recognized as a low load state. This means that the load borne by the device is relatively light, and it may be in an idle or lightly used state. For example, for a device with a rated power of 1000 watts, when the actual load power is less than or equal to 300 watts, it is in a low load state. When the load value is greater than 30% of the rated load value and less than or equal to 70% of the rated load value, it is determined as a normal load state. For the above device, when the load power is greater than 300 watts but less than or equal to 700 watts, it is within the normal operating range, neither overly lightly loaded nor overloaded. When the load value is greater than 70% of the rated load value, it is determined as a high load state. For this device, if the load power is greater than 700 watts, it indicates that the device is bearing a heavy load and may be close to or reaching its load limit. Correspondingly, in the low load state, the first voltage threshold is used. The second voltage threshold is adopted in the normal load state. It is set to the third voltage threshold in the high load state. It can be understood that the heavier the load of the device to be measured, the more likely it is to have a leakage fault. Therefore, in the high load state, it is set to the lowest third voltage threshold to give a timely reminder when a leakage fault occurs.
[0122] Optionally, determining the voltage warning threshold based on the voltage initial threshold includes:
[0123] Determining the voltage warning threshold based on the voltage initial threshold and the threshold adjustment factor.
[0124] In one embodiment, the voltage initial threshold and the threshold adjustment factor are combined based on a preset algorithm to obtain the voltage warning threshold.
[0125] Optionally, determining the voltage warning threshold based on the voltage initial threshold and the threshold adjustment factor includes:
[0126] Determining the voltage warning threshold based on the product of the voltage initial threshold and the threshold adjustment factor.
[0127] In one embodiment, the voltage warning threshold is determined by multiplying the voltage initial threshold by the threshold adjustment factor.
[0128] S202. Determine the ambient temperature state based on the ambient temperature information, determine the temperature initial threshold based on the ambient temperature state, and determine the temperature warning threshold based on the temperature initial threshold.
[0129] Among them, the ambient temperature state refers to the degree of hot or cold of the environment where the device to be measured is currently located. The initial temperature threshold is a preset temperature limit value.
[0130] In one embodiment, the collected ambient temperature data is processed and analyzed, such as calculating statistics such as the average value, maximum value, and minimum value. Considering factors such as seasonal changes, daily changes, and spatial changes of the ambient temperature, a comprehensive evaluation of the ambient temperature data is carried out. Considering the characteristics of the device and the working environment, the range of the initial temperature threshold corresponding to each ambient temperature state is determined, and the final temperature warning threshold is determined according to the initial temperature threshold and other operating parameters of the device.
[0131] Optionally, the ambient temperature information includes the ambient temperature value. Determining the ambient temperature state based on the ambient temperature information and determining the initial temperature threshold based on the ambient temperature state includes:
[0132] When the ambient temperature value is less than or equal to the first preset value, the ambient temperature state is a low temperature state, and the initial temperature threshold is the first temperature threshold;
[0133] When the ambient temperature value is greater than the first preset value and less than or equal to the second preset value, the ambient temperature state is a normal temperature state, and the initial temperature threshold is the second temperature threshold;
[0134] When the ambient temperature value is greater than the second preset value, the ambient temperature state is a high temperature state, and the initial temperature threshold is the third temperature threshold, where the first temperature threshold is greater than the second temperature threshold and the second temperature threshold is greater than the third temperature threshold.
[0135] Among them, the first preset value is a preset temperature value less than the second preset value, and is used to determine the temperature state of the environment where the device to be measured is currently located.
[0136] In one embodiment, when the ambient temperature value is less than or equal to the first preset value, it is determined to be in a low-temperature state. For example, if the first preset value is set to 10°C, when the measured ambient temperature value is less than or equal to 10°C, the environment is in a low-temperature state. When the ambient temperature value is greater than the first preset value and less than or equal to the second preset value, it is determined to be in a normal-temperature state. This is a relatively common temperature range within which the device can usually operate stably. For instance, if the first preset value is 10°C and the second preset value is 30°C, when the ambient temperature is greater than 10°C and less than or equal to 30°C, it is in a normal-temperature state. When the ambient temperature value is greater than the second preset value, it is determined to be in a high-temperature state. A high-temperature environment may have an adverse impact on the performance and lifespan of the device, and corresponding heat dissipation or protection measures need to be taken. Correspondingly, in the low-temperature state, the first temperature threshold is used. The second temperature threshold is adopted in the normal-temperature state. This threshold is usually determined according to the performance and stability of the device within the normal temperature range. The third temperature threshold is set in the high-temperature state. It can be understood that the lower the ambient temperature, the more conducive it is for the device under test to dissipate heat. Therefore, in a low-temperature environment, the ambient preset threshold can be relatively high. By dynamically adjusting the temperature initial threshold according to the ambient temperature state in this way, the device can better adapt to and operate in different ambient temperatures, improving the reliability and stability of the device.
[0137] Optionally, determining the temperature warning threshold based on the temperature initial threshold includes:
[0138] Determining the temperature warning threshold based on the temperature initial threshold and the threshold adjustment factor.
[0139] In one embodiment, the temperature initial threshold and the threshold adjustment factor are combined based on a preset algorithm to obtain the temperature warning threshold.
[0140] Determining the temperature warning threshold based on the temperature initial threshold and the threshold adjustment factor includes:
[0141] Determining the temperature warning threshold based on the product of the temperature initial threshold and the threshold adjustment factor.
[0142] In one embodiment, the temperature warning threshold is determined by multiplying the temperature initial threshold by the threshold adjustment factor.
[0143] As can be seen from the above, the adjustment factor is determined according to the operating duration of the device under test, and further the warning threshold is determined to ensure that the warning threshold can accurately reflect the operating state of the device and trigger a warning signal when necessary, thereby ensuring the safety and reliability of the device.
