A temperature early warning method and terminal based on electric energy control

Abstract

The application provides a temperature early warning method and terminal based on electric energy control. The temperature change of the current detected device is judged to be abnormal rising or falling by acquiring the energy storage voltage value and temperature data. When the energy storage voltage value and the temperature change are detected to exceed the voltage threshold and the temperature threshold, the current temperature value can be directly reported without waiting for the next data reporting period. In this way, the problem of high temperature caused by long data reporting period and untimely data reporting is avoided. The data reporting can be performed in advance for abnormal temperature, and the temperature early warning function is realized. After the data reporting is completed in advance, the working period is dynamically adjusted according to the energy storage voltage value, so that the electric energy consumed by the device during the sleep period for this data reporting is supplemented, and power failure shutdown caused by insufficient electric energy is avoided.

Description

[0001] This case is a divisional application based on the invention patent filed on August 7, 2023, with application number 202310988511.8 and titled "An Early Warning Method and Terminal for Wireless Temperature Measurement Using CT Power Supply". Technical Field

[0002] This invention relates to the field of online temperature detection technology, and in particular to a temperature early warning method and terminal based on power control. Background Technology

[0003] Initially, when CT (Current Transformer) power supply technology was applied to wireless temperature measurement devices, the devices were directly powered by the CT power supply module, rectifier, and step-down module. Due to limitations in size, weight, cost, and other factors, the efficiency of CT power supply was usually not very high. This placed high demands on the primary side current, typically requiring a primary side current of 50A or more for the device to start working, which greatly limited the application of CT-powered wireless temperature measurement devices.

[0004] Subsequent wireless temperature measurement devices incorporated an energy storage module and a voltage monitoring module. The energy storage module stores the electrical energy drawn from the CT power module, while the voltage monitoring module controls the energy storage module's output, ensuring sufficient power for the wireless temperature measurement device during operation. This hardware power management solution significantly reduces the primary current requirement, typically requiring only 5A or higher to start, thus broadening the application scenarios of CT-powered wireless temperature measurement devices. However, after startup, especially during wireless message transmission, the overall power consumption increases dramatically, quickly depleting the energy storage module and causing the device to shut down. The device then restarts once the energy storage module is fully charged, forming an intermittent operating mechanism.

[0005] To address the shortcomings of hardware-based power management solutions and ensure stable online operation, a software-based power management scheme was later incorporated. Upon startup, the software puts the entire device into a sleep mode to reduce power consumption, allowing the energy storage module to continue charging and storing more energy. Then, the software puts the device into wireless transmission mode to report the collected temperature values, before returning to sleep mode for charging. This periodic cycle of sleep charging and wireless temperature reporting ensures stable online operation. However, to ensure stable online operation even with a typical primary current of 5A, the sleep charging cycle is set to be relatively long. If significant temperature changes occur during the sleep period, and data cannot be reported in a timely manner, it could lead to equipment damage, personal injury, and economic losses. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a temperature early warning method and terminal based on power control, which can provide early warning and report according to temperature changes, thereby solving the problem of untimely data reporting.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0008] A temperature early warning method based on power control includes the following steps:

[0009] Acquire energy storage voltage and temperature data;

[0010] Determine whether the energy storage voltage value and the temperature data meet the preset early warning conditions. If so, directly report the current temperature value and adjust the working cycle according to the energy storage voltage value.

[0011] Otherwise, obtain the current working cycle and report the current temperature value according to the working cycle.

[0012] To solve the above-mentioned technical problems, another technical solution adopted by the present invention is as follows:

[0013] A temperature warning terminal based on power control includes a memory, a processor, and a computer program stored in the memory and running on the processor. When the processor executes the computer program, it performs the following steps:

[0014] Acquire energy storage voltage and temperature data;

[0015] Determine whether the energy storage voltage value and the temperature data meet the preset early warning conditions. If so, directly report the current temperature value and adjust the working cycle according to the energy storage voltage value.

[0016] Otherwise, obtain the current working cycle and report the current temperature value according to the working cycle.

[0017] The beneficial effects of this invention are as follows: by acquiring the energy storage voltage value and temperature data, it can determine whether there is an abnormality in the temperature of the device being tested. When the energy storage voltage value and temperature data meet the preset warning conditions, the current temperature value can be reported directly without waiting for the next data reporting cycle. This avoids the problem of excessively high temperature caused by excessively long data reporting cycles and untimely data reporting. Abnormal temperatures can be reported in advance, realizing the temperature warning function. After completing the data reporting in advance, the working cycle is dynamically adjusted according to the energy storage voltage value to ensure that the device replenishes the power consumed by this data reporting during the sleep period, avoiding power failure and shutdown due to insufficient power, which would affect the next data reporting.

[0022] Label Explanation:

[0023] 301. Memory; 302. Processor. Detailed Implementation

[0024] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0025] Please refer to Figure 1 This invention provides a temperature early warning method based on power control, comprising the following steps:

[0026] Acquire energy storage voltage and temperature data;

[0027] Determine whether the energy storage voltage value and the temperature data meet the preset early warning conditions. If so, directly report the current temperature value and adjust the working cycle according to the energy storage voltage value.

[0028] Otherwise, obtain the current working cycle and report the current temperature value according to the working cycle.

[0029] As can be seen from the above description, the beneficial effects of the present invention are as follows: by acquiring the energy storage voltage value and temperature data, it can determine whether there is an abnormality in the temperature of the device being tested. When the energy storage voltage value and temperature data meet the preset warning conditions, the current temperature value can be reported directly without waiting for the next data reporting cycle. This avoids the problem of excessively high temperature caused by excessively long data reporting cycles and untimely data reporting. Abnormal temperatures can be reported in advance, realizing the temperature warning function. After completing the data reporting in advance, the working cycle is dynamically adjusted according to the energy storage voltage value to ensure that the device replenishes the power consumed by this data reporting during the sleep period, avoiding power failure and shutdown due to insufficient power, which would affect the next data reporting.

[0030] Furthermore, the energy storage voltage value includes historical voltage values ​​and current voltage values;

[0031] The process of obtaining the energy storage voltage value includes:

[0032] Obtain the historical voltage value before hibernation and the current voltage value after hibernation;

[0033] The primary current value is obtained based on the historical voltage value and the current voltage value;

[0034] Determine whether the primary current value meets the preset current limit. If so, proceed to the step of determining whether the energy storage voltage value and the temperature data meet the preset warning conditions.

[0035] Otherwise, proceed with the steps of obtaining the current work cycle and reporting the current temperature value according to the work cycle.

[0036] As described above, the primary current value is obtained by comparing the voltage values ​​before and after sleep mode, and the decision to execute the early warning function is based on this value. When the primary current value exceeds the current limit, the device has sufficient power and can report data in real time, without the problem of excessively long sleep time. However, when the primary current value is less than the current limit, the device has insufficient power to support early data reporting. Only when the primary current value meets the preset current limit may there be a problem of excessively long sleep time leading to untimely data reporting, requiring the use of temperature data to determine whether to execute the early warning function. In this way, early data reporting is achieved without causing power shortages and shutdowns due to early data reporting, ensuring the timeliness of the next data report and improving the effectiveness and timeliness of the device's data reporting.

[0037] Furthermore, acquiring the temperature data includes:

[0038] Obtain the historical temperature value before hibernation and the current temperature value after hibernation;

[0039] The rate of temperature change is calculated based on the historical temperature value and the current temperature value.

[0040] As described above, by obtaining the temperature values ​​before and after hibernation, it is possible to determine whether the temperature changes during hibernation are normal, thereby confirming whether there are any abnormalities in the temperature data during hibernation.

[0041] Furthermore, the temperature data includes the current temperature value or the rate of temperature change, and the step of determining whether the energy storage voltage value and the temperature data meet the preset warning conditions includes:

[0042] Obtain the preset voltage threshold and preset temperature threshold;

[0043] When both the energy storage voltage value and the current temperature value are greater than the preset voltage threshold and the preset temperature threshold, it is determined that the preset warning condition is met; or

[0044] Obtain the preset voltage threshold and preset temperature change threshold;

[0045] When both the energy storage voltage value and the temperature change rate are greater than the preset voltage threshold and the preset temperature change threshold, it is determined that the preset warning condition is met.

[0046] As described above, the preset early warning condition is met when both the energy storage voltage and the current temperature value are greater than their respective thresholds; or when both the energy storage voltage and the rate of temperature change are greater than their respective thresholds. The energy storage voltage is greater than the voltage threshold to ensure that the current device has sufficient power to support the early reporting of data. The current temperature value or rate of temperature change is used to determine whether the current temperature is abnormal. In this way, the effectiveness of the data reporting is ensured.

[0047] Furthermore, the temperature data includes the current temperature value and the rate of temperature change. The step of determining whether the energy storage voltage value and the temperature data meet preset warning conditions includes:

[0048] Obtain preset voltage threshold, preset temperature threshold, and preset temperature change threshold;

[0049] When the energy storage voltage value, the current temperature value, and the temperature change rate are all greater than the preset voltage threshold, the preset temperature threshold, and the preset temperature change threshold, it is determined that the preset warning condition is met.

[0050] As described above, when the energy storage voltage, current temperature, and rate of temperature change all exceed their respective thresholds, the preset early warning conditions are met. The energy storage voltage exceeds the voltage threshold to ensure sufficient power for the device to support early data reporting. The current temperature and rate of temperature change are used to determine if the current temperature is abnormal, thus ensuring the effectiveness and timeliness of data reporting.

[0051] Furthermore, the preset voltage threshold includes at least a first voltage value and a second voltage value, the preset temperature threshold includes at least a first temperature value and a second temperature value, and the preset temperature change threshold includes at least a first change value and a second change value;

[0052] When the energy storage voltage, the current temperature, and the rate of temperature change are all greater than the preset voltage threshold, the preset temperature threshold, and the preset temperature change threshold, it is determined that the preset warning condition is met, including:

[0053] Determine whether the energy storage voltage value is greater than the first voltage value;

[0054] If the energy storage voltage value is greater than the first voltage value, then the first temperature value and the first change value are obtained. When the current temperature value and the temperature change rate are both greater than the first temperature value and the first change value, then it is determined that the preset warning condition is met.

[0055] If the energy storage voltage value is not greater than the first voltage value, then determine whether the energy storage voltage value is greater than or equal to the second voltage value. If so, then obtain the second temperature value and the second change value. When the current temperature value and the temperature change rate are both greater than the second temperature value and the first change value, then determine that the preset warning condition is met.

[0056] As described above, when the energy storage voltage is greater than the first voltage value, the higher voltage ensures that the device is less likely to lose power while supporting early data reporting. Therefore, the first temperature value and the first change value are acquired to improve the sensitivity of the temperature warning. When the energy storage voltage is greater than the second voltage value but not the first, the lower voltage may cause power loss after data reporting. Therefore, the second temperature value and the second change value are acquired to reduce the sensitivity of the temperature warning. When the energy storage voltage is less than the second voltage value, the insufficient energy to support data reporting prevents the warning function from being executed, maintaining low-power operation and avoiding device shutdown due to power failure. This method achieves intelligent adjustment of the temperature warning sensitivity, avoiding untimely data reporting caused by excessively long sleep times while ensuring that the device's power is not frequently consumed by the temperature warning function.

[0057] Furthermore, adjusting the working cycle according to the energy storage voltage value includes:

[0058] Obtain the periodic compensation coefficient corresponding to different energy storage voltage values, calculate the compensation period based on the periodic compensation coefficient, and adjust the working cycle based on the compensation period.

[0059] As described above, after the data is reported in advance, in order to compensate for the power consumed in the data reporting, the corresponding periodic compensation coefficient is obtained based on the energy storage voltage value, thereby obtaining the compensation period to adjust the working cycle, ensuring that the device can replenish the power consumed in this reporting during the sleep period, and avoiding the problem of power failure and shutdown after the device completes the early warning function.

[0060] Please refer to Figure 3 Another embodiment of the present invention provides a temperature warning terminal based on power control, including a memory, a processor, and a computer program stored in the memory and running on the processor. When the processor executes the computer program, it performs the following steps:

[0061] Acquire energy storage voltage and temperature data;

[0062] Determine whether the energy storage voltage value and the temperature data meet the preset early warning conditions. If so, directly report the current temperature value and adjust the working cycle according to the energy storage voltage value.

[0063] Otherwise, obtain the current working cycle and report the current temperature value according to the working cycle.

[0064] As can be seen from the above description, the beneficial effects of the present invention are as follows: by acquiring the energy storage voltage value and temperature data, it can determine whether there is an abnormality in the temperature of the device being tested. When the energy storage voltage value and temperature data meet the preset warning conditions, the current temperature value can be reported directly without waiting for the next data reporting cycle. This avoids the problem of excessively high temperature caused by excessively long data reporting cycles and untimely data reporting. Abnormal temperatures can be reported in advance, realizing the temperature warning function. After completing the data reporting in advance, the working cycle is dynamically adjusted according to the energy storage voltage value to ensure that the device replenishes the power consumed by this data reporting during the sleep period, avoiding power failure and shutdown due to insufficient power, which would affect the next data reporting.

[0065] Furthermore, the energy storage voltage value includes historical voltage values ​​and current voltage values;

[0066] The process of obtaining the energy storage voltage value includes:

[0067] Obtain the historical voltage value before hibernation and the current voltage value after hibernation;

[0068] The primary current value is obtained based on the historical voltage value and the current voltage value;

[0069] Determine whether the primary current value meets the preset current limit. If so, proceed to the step of determining whether the energy storage voltage value and the temperature data meet the preset warning conditions.

[0070] Otherwise, proceed with the steps of obtaining the current work cycle and reporting the current temperature value according to the work cycle.

[0071] As described above, the primary current value is obtained by comparing the voltage values ​​before and after sleep mode, and the decision to execute the early warning function is based on this value. When the primary current value exceeds the current limit, the device has sufficient power and can report data in real time, without the problem of excessively long sleep time. However, when the primary current value is less than the current limit, the device has insufficient power to support early data reporting. Only when the primary current value meets the preset current limit may there be a problem of excessively long sleep time leading to untimely data reporting, requiring the use of temperature data to determine whether to execute the early warning function. In this way, early data reporting is achieved without causing power shortages and shutdowns due to early data reporting, ensuring the timeliness of the next data report and improving the effectiveness and timeliness of the device's data reporting.

[0072] Furthermore, acquiring the temperature data includes:

[0073] Obtain the historical temperature value before hibernation and the current temperature value after hibernation;

[0074] The rate of temperature change is calculated based on the historical temperature value and the current temperature value.

[0075] As described above, by obtaining the temperature values ​​before and after hibernation, it is possible to determine whether the temperature changes during hibernation are normal, thereby confirming whether there are any abnormalities in the temperature data during hibernation.

[0076] This invention provides a temperature early warning method and terminal based on power control, which can be applied to devices powered by a CT scanner. Based on temperature changes, it provides early warnings and reports, solving the problem of untimely data reporting. Specific embodiments are described below:

[0077] Please refer to Figures 1 to 2 Embodiment 1 of the present invention:

[0078] A temperature early warning method based on power control includes the following steps:

[0079] S1. Obtain the energy storage voltage and temperature data.

[0080] Specifically, the energy storage voltage value includes historical voltage values ​​and current voltage values.

[0081] In step S1, obtaining the energy storage voltage value includes:

[0082] S11. Obtain the historical voltage value before hibernation and the current voltage value after hibernation.

[0083] S12. Obtain the primary side current value based on the historical voltage value and the current voltage value.

[0084] S13. Determine whether the primary current value meets the preset current limit. If yes, proceed to step S2; otherwise, proceed to step S4.

[0085] In step S1, acquiring temperature data includes:

[0086] S14. Obtain the historical temperature value before hibernation and the current temperature value after hibernation.

[0087] S15 calculates the rate of temperature change based on the historical temperature value and the current temperature value.

[0088] In some embodiments, S15 specifically includes:

[0089] ;

[0090] Among them, K t It represents the rate of temperature change, where Temp1 is the historical temperature value before hibernation, Temp2 is the current voltage value after hibernation, and T... w This refers to the actual work cycle.

[0091] S2. Determine whether the energy storage voltage value and the temperature data meet the preset warning conditions; if yes, proceed to step S3; otherwise, proceed to step S4.

[0092] In one optional implementation, the temperature data includes the current temperature value and the rate of temperature change, then S2 includes:

[0093] S21. Obtain the preset voltage threshold, preset temperature threshold, and preset temperature change threshold.

[0094] S22. When the energy storage voltage value, the current temperature value, and the temperature change rate are all greater than the preset voltage threshold, the preset temperature threshold, and the preset temperature change threshold, it is determined that the preset warning condition is met.

[0095] In one optional implementation, the preset voltage threshold includes at least a first voltage value and a second voltage value, the preset temperature threshold includes at least a first temperature value and a second temperature value, and the preset temperature change threshold includes at least a first change value and a second change value.

[0096] Then S22 includes:

[0097] S221. Determine whether the energy storage voltage value is greater than the first voltage value;

[0098] S222. If the energy storage voltage value is greater than the first voltage value, then obtain the first temperature value and the first change value. When the current temperature value and the temperature change rate are both greater than the first temperature value and the first change value, then determine that the preset warning condition is met.

[0099] S223. If the energy storage voltage value is not greater than the first voltage value, then determine whether the energy storage voltage value is greater than or equal to the second voltage value. If so, then obtain the second temperature value and the second change value. When the current temperature value and the temperature change rate are both greater than the second temperature value and the first change value, then determine that the preset warning condition is met.

[0100] It should be noted that if the first voltage value is greater than the second voltage value, then the first temperature value and the first change value corresponding to the first voltage value are both less than the second temperature value and the second change value corresponding to the second voltage value; conversely, if the first temperature value and the first change value are less than the second voltage value, then the first temperature value and the first change value are both greater than the second temperature value and the second change value corresponding to the second voltage value. This method avoids false alarms caused by abnormal temperature change rates when the temperature has not reached a level that would affect equipment safety.

[0101] In some embodiments, the first voltage value is 5V, the second voltage value is 4V; the first change value is 1℃ / minute, the first temperature value is 50℃; the second change value is 3℃ / minute, the second temperature value is 70℃.

[0102] It should be noted that all energy storage voltage values ​​mentioned are current voltage values.

[0103] That is, when the energy storage voltage value is greater than the first voltage value, the current temperature value is greater than the first temperature value, and the temperature change rate is greater than or equal to the first change value, step S3 is executed.

[0104] When the energy storage voltage value is not greater than the first voltage value but greater than the second voltage value, the current temperature value is greater than or equal to the second temperature value, and the temperature change rate is greater than the second change value, step S3 is executed.

[0105] If the energy storage voltage value, current temperature value, or temperature change rate does not exceed the corresponding threshold, proceed to step S4.

[0106] In some embodiments, when the energy storage voltage U>5V, the temperature change rate ≥1℃ / minute, and the current temperature value Temp2≥50℃ are all satisfied simultaneously, step S3 is executed.

[0107] In some embodiments, when the energy storage voltage value 5V≥U≥4V, the temperature change rate ≥3℃ / minute, and the current temperature value Temp2≥70℃ are all satisfied simultaneously, step S3 is executed.

[0108] In some embodiments, when the energy storage voltage value U < 4V, step S4 is executed.

[0109] S3. Directly report the current temperature value and adjust the working cycle according to the energy storage voltage value.

[0110] In step S3: adjusting the working cycle according to the energy storage voltage value includes:

[0111] S31. Obtain the periodic compensation coefficient corresponding to different energy storage voltage values, calculate the compensation period based on the periodic compensation coefficient, and adjust the working cycle based on the compensation period.

[0112] It should be noted that a higher energy storage voltage corresponds to a lower cycle compensation coefficient, while a lower energy storage voltage corresponds to a higher cycle compensation coefficient. Since a higher energy storage voltage indicates higher electrical energy, the remaining electrical energy after the current data report is greater than the remaining electrical energy when the energy storage voltage is low. Therefore, before the next wireless data report, the required sleep time (i.e., charging time) when the energy storage voltage is high is less than the required sleep time (charging time) when the energy storage voltage is low. Specifically, S31 refers to the actual working cycle T. w =Basic working cycle T' + Basic working cycle T' × Period compensation coefficient.

[0113] In some embodiments, when the energy storage voltage U>5V, the corresponding period compensation coefficient is 0.1, and when the energy storage voltage 5V≥U≥4V, the corresponding period compensation coefficient is 0.3.

[0114] S4. Obtain the current working cycle and report the current temperature value according to the working cycle.

[0115] In some embodiments, S4 includes:

[0116] S41. Obtain the current working cycle and the total sleep time, and determine whether the total sleep time is greater than or equal to the working cycle. If yes, proceed to steps S42 to S43; otherwise, proceed to step S1.

[0117] S42. Report the current temperature value and reset the total sleep time to zero.

[0118] S43. Adjust the working cycle according to the primary current value.

[0119] It should be noted that since each sleep cycle is a fixed value, the decision to perform data reporting is based on the relationship between the total sleep time and the working cycle, so that the device's sleep time (charging time) can be extended or shortened synchronously according to the working cycle.

[0120] Please refer to Figures 2 to 3 Embodiment 2 of the present invention:

[0121] The difference between this embodiment and Embodiment 1 is that it specifies the specific implementation of step S43, namely, steps A110 to A114 below, as follows. Figure 3 As shown.

[0122] A temperature early warning method based on power control includes the following steps:

[0123] If the device is powered on for the first time, the current operating mode is low power mode by default, and the current actual working cycle is 60 seconds by default.

[0124] Step A1: Obtain the historical voltage value V1 and historical temperature value Temp1 before hibernation, the current voltage value V2 and current temperature value Temp2 after hibernation, and the hibernation period T. s .

[0125] Step A2: Calculate the rate of temperature change K based on the historical temperature value Temp1 and the current temperature value Temp2. t ;

[0126] Step A3: Based on the historical voltage value V1, the current voltage value V2, and the sleep period T s Obtain the charging rate K c ;

[0127] In this embodiment, A3 specifically refers to:

[0128] ;

[0129] Among them, K c This refers to the charging rate, V1 is the historical voltage value before sleep mode, V2 is the current voltage value after sleep mode, and T... s This is the dormancy cycle.

[0130] Step A4: According to the charging rate K c Calculate the current primary current value I p ;

[0131] In this embodiment, A3 specifically refers to:

[0133] Among them, I p This is the primary side current value, C is the capacitance value of the energy storage module, and K... i This refers to the power extraction coefficient of the CT power module. Specifically, I1 represents the average value of the primary side current provided by the CT power supply module, and I2 represents the average value of the secondary side current provided by the CT power supply module.

[0134] Step A5: Obtain the current actual working cycle T w ;

[0135] Step A6: According to the sleep cycle Ts Get the current total sleep time T sum .

[0136] Step A7: Determine whether the current working mode is balanced mode. If yes, proceed to steps A80 to A84; otherwise, proceed to step A9.

[0137] Step A80: Determine whether the current voltage value V2 is greater than the first voltage value 5V. If yes, proceed to step A81; otherwise, proceed to step A82.

[0138] Step A81: Obtain the first change value as 1℃ / minute and the first temperature value as 50℃, and determine the temperature change rate K. t If the current temperature value Temp2 is greater than or equal to 1℃ / minute, and if it is greater than or equal to 50℃, then proceed to step A84; otherwise, proceed to step A9.

[0139] Step A82: Determine whether the current voltage value V2 is greater than or equal to the second voltage value 4V. If yes, proceed to step A83; otherwise, proceed to step A9.

[0140] Step A83: Obtain the second change value as 3℃ / minute and the second temperature value as 70℃, and determine the temperature change rate K. t If the current temperature value Temp2 is greater than or equal to 3℃ / minute, and greater than or equal to 70℃, then proceed to step A84; otherwise, proceed to step A9.

[0141] Step A84: Directly report the current temperature value wirelessly and obtain the cycle compensation coefficient corresponding to the current voltage value V2 (if the current voltage value V2 > 5V, the obtained cycle compensation coefficient is 0.1; if the current voltage value 5V ≥ V2 ≥ 4V, the obtained cycle compensation coefficient is 0.3); obtain the working cycle corresponding to the current working mode as the basic working cycle T', calculate the compensation cycle based on the cycle compensation coefficient (0.1 or 0.3) and the basic working cycle, and obtain the adjusted actual working cycle T. w =Basic working cycle T' + Compensation cycle T b .

[0142] It should be noted that if step A84 is executed, then the current actual working cycle mentioned in step A9 is the adjusted actual working cycle T. w .

[0143] Step A9: Determine the current total sleep time T sum Is it greater than or equal to the current actual working cycle T? w If yes, proceed to step A10; otherwise, return to step A1.

[0144] Step A10: Wirelessly report the current temperature value and the current total sleep time T. sum Clear the cache and proceed with steps A110-A114.

[0145] Step A110: Determine the primary side current value I p If the value is greater than the preset threshold 50A, proceed to step A111; otherwise, proceed to step A112.

[0146] Step A111: Switch the current working mode to high-performance mode, obtain the preset working cycle of 30s for high-performance mode as the basic working cycle T', and return to execute step A1.

[0147] Step A112: Determine the primary side current value I p If the current is greater than or equal to the first current limit of 5A, proceed to step A113; otherwise, proceed to step A114.

[0148] Step A113: Switch the current operating mode to equalization mode, and adjust the operating mode according to the primary side current value I. p Obtain the first dynamic working cycle T1 of the balanced mode as the basic working cycle T', and return to execute step A1.

[0149] In this embodiment, the step of basing the primary side current value I p The first dynamic working cycle T1 of the equilibrium mode is specifically as follows:

[0150] .

[0151] Step A114: Switch the current operating mode to low-power mode, and based on the primary side current value I... p Obtain the second dynamic working cycle T2 of the low-power mode as the basic working cycle T', and return to execute step A1.

[0152] In this embodiment, the step of basing the primary side current value I p The second dynamic duty cycle T2 for obtaining the low-power mode is specifically as follows:

[0153] T2=-100×I p +800.

[0154] That is, when the primary side current value I p When the current current output is >50A, the operating mode switches to high-performance mode.

[0155] When 50A ≥ primary current value I p When the current operating temperature is ≥5A, the current operating mode is switched to balanced mode;

[0156] When the primary current value I pWhen the current power consumption is less than 5A, the current operating mode switches to low power mode.

[0157] Embodiment 3 of the present invention:

[0158] The difference between this embodiment and Embodiment 1 is that it specifies another specific implementation method for step S2.

[0191] Please refer to Figure 4 Embodiment 5 of the present invention:

[0192] A temperature warning terminal based on power control includes a memory 301, a processor 302, and a computer program stored in the memory 301 and running on the processor 302.

[0193] In summary, the present invention provides a temperature early warning method and terminal based on power control. By acquiring energy storage voltage and temperature data, it determines whether there are abnormal increases or decreases in the temperature of the monitored device. When both the energy storage voltage and temperature data meet the preset early warning conditions, the current temperature value can be reported directly without waiting for the next data reporting cycle. This avoids the problem of excessively high temperatures caused by excessively long data reporting cycles and untimely data reporting. Abnormal temperatures can be reported in advance, realizing the temperature early warning function. After completing the data reporting in advance, the working cycle is dynamically adjusted according to the energy storage voltage value to ensure that the device replenishes the power consumed by this data reporting during the sleep period, avoiding power failure and shutdown due to insufficient power. At the same time, data reporting is performed based on the relative relationship between the total sleep time and the working cycle, and the working cycle is intelligently adjusted according to the fluctuation of the primary side current value. This allows the primary side current value to indirectly adjust the sleep cycle, preventing power failure and shutdown due to fluctuations in the primary side current value, and making its working mode more flexible and applicable to more severe working conditions.
