Description

[0001] This case is a divisional application based on the invention patent with application date of 2023-08-07, application number 202310988511.8, and name "A warning method and terminal for CT power supply wireless temperature measurement" as the parent case. Technical Field

[0002] The present invention relates to the technical field of online temperature detection, and in particular to a temperature early warning method and terminal based on electric energy control. Background Art

[0003] When CT (Current Transformer) power supply technology was first applied to wireless temperature measuring devices, the wireless temperature measuring 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 is usually not very high, which places high requirements on the size of the primary side current. Usually, the primary side current must be above 50A to start the device, which greatly limits the application of CT-powered wireless temperature measuring devices.

[0004] Later wireless temperature measuring devices added energy storage modules and voltage monitoring modules. The energy storage module stores the electric energy obtained from the CT power module, and the voltage monitoring module controls the external output of the energy storage module to ensure that the wireless temperature measuring device has sufficient power when working. With this hardware power management solution, the requirements for the size of the primary current are greatly reduced. Usually, only more than 5A is required to start the device, which broadens the application scenarios of CT power-based wireless temperature measuring devices; but after starting work, especially transmitting wireless messages, the power consumption of the entire device will increase greatly, and the power in the energy storage module will be quickly consumed, and the device will be powered off and shut down; then wait until the next time the energy storage module is fully charged, the device will start working again, forming an intermittent working mechanism.

[0005] In order to solve the defects of the hardware power management solution and enable the device to work stably online, the subsequent technical solution added a software power management solution. When the device starts working, the software puts the entire device into sleep mode to reduce power consumption, allowing the energy storage module to continue charging and storing more power; then the software puts the device into wireless transmission mode, reports the collected temperature value, and then continues to put the device into sleep mode for charging; in this way, the device is put into sleep mode for charging periodically, and then the temperature value is wirelessly reported, so that the device can run stably online. In order to allow the device to run stably online even when the primary side current is usually 5A, the sleep charging cycle time is set to be relatively long. If the temperature changes significantly during the sleep period, the data cannot be reported in time, which may cause 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 warning method and terminal based on electric energy control, which can report early warning according to the temperature change and solve the problem of untimely data reporting.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is: A temperature early warning method based on electric energy control comprises the following steps: Obtain energy storage voltage value and temperature data; Determine whether the energy storage voltage value and the temperature data meet the preset warning conditions. If so, directly report the current temperature value and adjust the working cycle according to the energy storage voltage value; Otherwise, the current working cycle is obtained, and the current temperature value is reported according to the working cycle.

[0008] In order to solve the above technical problems, another technical solution adopted by the present invention is: A temperature warning terminal based on electric energy 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, the following steps are implemented: Obtain energy storage voltage value and temperature data; Determine whether the energy storage voltage value and the temperature data meet the preset warning conditions. If so, directly report the current temperature value and adjust the working cycle according to the energy storage voltage value; Otherwise, the current working cycle is obtained, and the current temperature value is reported according to the working cycle.

[0009] The beneficial effects of the present invention are as follows: by acquiring the energy storage voltage value and temperature data, it is determined whether there is an abnormal problem with the temperature of the current detected device. When it is detected that the energy storage voltage value and temperature data meet the preset warning conditions, there is no need to wait for the next data reporting cycle, and the current temperature value can be directly reported. In this way, the problem of excessive temperature caused by too long a data reporting cycle and untimely data reporting is avoided. For abnormal temperature, data reporting can be performed in advance to realize the temperature warning function. After the data reporting is completed in advance, the working cycle is dynamically adjusted according to the energy storage voltage value to ensure that the device replenishes the electric energy consumed by the data reporting during the sleep period, so as to avoid power failure and shutdown caused by insufficient power affecting the next data reporting.

[0011] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0012] Please refer to Figure 1 The embodiment of the present invention provides a temperature warning method based on electric energy control, comprising the steps of: Obtain energy storage voltage value and temperature data; Determine whether the energy storage voltage value and the temperature data meet the preset warning conditions. If so, directly report the current temperature value and adjust the working cycle according to the energy storage voltage value; Otherwise, the current working cycle is obtained, and the current temperature value is reported according to the working cycle.

[0013] From the above description, it can be seen that the beneficial effects of the present invention are: by obtaining the energy storage voltage value and temperature data, it is determined whether there is an abnormal problem in the temperature of the current detected device. When it is detected that the energy storage voltage value and temperature data meet the preset warning conditions, there is no need to wait for the next data reporting cycle, and the current temperature value can be directly reported. In this way, the problem of excessive temperature caused by too long data reporting cycle and untimely data reporting can be avoided. For abnormal temperature, data can be reported in advance to realize 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 electric energy consumed by this data reporting during the sleep period, so as to avoid power failure and shutdown caused by insufficient power affecting the next data reporting.

[0014] Furthermore, the energy storage voltage value includes a historical voltage value and a current voltage value; The obtaining of the energy storage voltage value comprises: Get the historical voltage value before sleep and the current voltage value after sleep; Acquire a primary side current value according to the historical voltage value and the current voltage value; Determine whether the primary side current value meets the preset current limit, and if so, execute the step of determining whether the energy storage voltage value and the temperature data meet the preset warning condition; Otherwise, the steps of obtaining the current working cycle and reporting the current temperature value according to the working cycle are performed.

[0015] From the above description, it can be known that the primary current value is obtained through the voltage value before and after sleep, and whether to execute the early warning function is determined according to the primary current value. Because when the primary current value is greater than the current limit, the device is sufficiently powered and can report data in real time, and there is no problem of too long sleep time; when the primary current value is less than the current limit, the device power supply is too low, which is not enough to support the device to report data in advance; only when the primary current value meets the preset current limit, there may be a problem of too long sleep time causing data to be reported untimely, and it is necessary to determine whether to execute the early warning function through temperature data. In this way, while realizing early data reporting, the device will not be shut down due to insufficient power due to the current early data reporting, ensuring the timeliness of the next data reporting and improving the effectiveness and timeliness of the device data reporting.

[0016] Further, the obtaining of temperature data includes: Get the historical temperature value before hibernation and the current temperature value after hibernation; The temperature change rate is calculated according to the historical temperature value and the current temperature value.

[0017] From the above description, it can be known that by obtaining the temperature values ​​before and after hibernation, it is determined whether the temperature change during hibernation is normal, so as to confirm whether there is any abnormality in the temperature data during hibernation.

[0018] Further, the temperature data includes a current temperature value or a temperature change rate, and the determining whether the energy storage voltage value and the temperature data meet a preset warning condition includes: Obtaining a preset voltage threshold and a preset temperature threshold; When the energy storage voltage value and the current temperature value are both greater than the preset voltage threshold and the preset temperature threshold, it is determined that the preset warning condition is met; or Obtaining a preset voltage threshold and a preset temperature change threshold; When the energy storage voltage value and the temperature change rate are both greater than the preset voltage threshold and the preset temperature change threshold, it is determined that the preset warning condition is met.

[0019] From the above description, it can be seen that when the energy storage voltage value and the current temperature value are both greater than the corresponding threshold value, the preset warning condition is met; or when the energy storage voltage value and the temperature change rate are both greater than the corresponding threshold value, the preset warning condition is met. The energy storage voltage value is greater than the voltage threshold to ensure that the current device has enough power to support early reporting of data, and the current temperature value or temperature change rate is used to determine whether the current temperature is abnormal. In this way, the validity of data reporting is guaranteed.

[0020] Further, the temperature data includes a current temperature value and a temperature change rate, and the determining whether the energy storage voltage value and the temperature data meet a preset warning condition includes: Obtaining a preset voltage threshold, a preset temperature threshold, and a preset temperature change threshold; 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.

[0021] From the above description, it can be seen that when the energy storage voltage value, the current temperature value and the temperature change rate are all greater than the corresponding thresholds, the preset warning condition is met. The energy storage voltage value is greater than the voltage threshold to ensure that the current device has enough power to support early reporting of data, and the current temperature value and temperature change rate are used to determine whether the current temperature is abnormal. In this way, the effectiveness and timeliness of data reporting are guaranteed.

[0022] Further, 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; 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, including: Determining whether the energy storage voltage value is greater than a first voltage value; If the energy storage voltage value is greater than the first voltage value, a first temperature value and a 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, it is determined that the preset warning condition is met.

[0023] If the energy storage voltage value is not greater than the first voltage value, determine whether the energy storage voltage value is greater than or equal to the second voltage value. If so, 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, it is determined that the preset warning conditions are met.

[0024] It can be seen from the above description that when the energy storage voltage value is greater than the first voltage value, since the energy storage voltage value is relatively high at this time, its electric energy is not prone to power failure while supporting early reporting of data, so the first temperature value and the first change value are obtained to improve the sensitivity of the temperature warning. When the energy storage voltage value is not greater than the first voltage value but greater than the second voltage value, since the energy storage voltage value is relatively low at this time, its electric energy may have a power failure problem after reporting data, so the second temperature value and the second change value are obtained to reduce the sensitivity of the temperature warning. When the energy storage voltage value is less than the second voltage value, the energy storage voltage value is too low at this time, and its electric energy is insufficient to support the reporting of data, then the warning function is not executed, and low power consumption operation is maintained to avoid power failure and shutdown of the device. In this way, the sensitivity of the temperature warning is intelligently adjusted to avoid the untimely reporting of data due to the long sleep time, while ensuring that the device electric energy will not be frequently consumed by the temperature warning function.

[0025] Further, adjusting the working cycle according to the energy storage voltage value includes: The cycle compensation coefficients corresponding to different energy storage voltage values ​​are obtained, and the compensation cycle is calculated according to the cycle compensation coefficients, and the working cycle is adjusted according to the compensation cycle.

[0026] From the above description, it can be seen that after reporting the data in advance, in order to compensate for the electric energy consumed in the data reporting, the corresponding period compensation coefficient is obtained according to the energy storage voltage value, so as to obtain the compensation period to adjust the working cycle, thereby ensuring that the device can replenish the electric energy consumed during the sleep period, and avoiding the problem of power failure and shutdown of the device after completing the early warning function.

[0027] Please refer to Figure 3 Another embodiment of the present invention provides a temperature warning terminal based on electric energy control, comprising a memory, a processor, and a computer program stored in the memory and running on the processor, wherein the processor implements the following steps when executing the computer program: Obtain energy storage voltage value and temperature data; Determine whether the energy storage voltage value and the temperature data meet the preset warning conditions. If so, directly report the current temperature value and adjust the working cycle according to the energy storage voltage value; Otherwise, the current working cycle is obtained, and the current temperature value is reported according to the working cycle.

[0028] From the above description, it can be seen that the beneficial effects of the present invention are: by obtaining the energy storage voltage value and temperature data, it is determined whether there is an abnormal problem in the temperature of the current detected device. When it is detected that the energy storage voltage value and temperature data meet the preset warning conditions, there is no need to wait for the next data reporting cycle, and the current temperature value can be directly reported. In this way, the problem of excessive temperature caused by too long data reporting cycle and untimely data reporting can be avoided. For abnormal temperature, data can be reported in advance to realize 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 electric energy consumed by this data reporting during the sleep period, so as to avoid power failure and shutdown caused by insufficient power affecting the next data reporting.

[0029] Furthermore, the energy storage voltage value includes a historical voltage value and a current voltage value; The obtaining of the energy storage voltage value comprises: Get the historical voltage value before sleep and the current voltage value after sleep; Acquire a primary side current value according to the historical voltage value and the current voltage value; Determine whether the primary side current value meets the preset current limit, and if so, execute the step of determining whether the energy storage voltage value and the temperature data meet the preset warning condition; Otherwise, the steps of obtaining the current working cycle and reporting the current temperature value according to the working cycle are performed.

[0030] From the above description, it can be known that the primary current value is obtained through the voltage value before and after sleep, and whether to execute the early warning function is determined according to the primary current value. Because when the primary current value is greater than the current limit, the device is sufficiently powered and can report data in real time, and there is no problem of too long sleep time; when the primary current value is less than the current limit, the device power supply is too low, which is not enough to support the device to report data in advance; only when the primary current value meets the preset current limit, there may be a problem of too long sleep time causing data to be reported untimely, and it is necessary to determine whether to execute the early warning function through temperature data. In this way, while realizing early data reporting, the device will not be shut down due to insufficient power due to the current early data reporting, ensuring the timeliness of the next data reporting and improving the effectiveness and timeliness of the device data reporting.

[0031] Further, the obtaining of temperature data includes: Get the historical temperature value before hibernation and the current temperature value after hibernation; The temperature change rate is calculated according to the historical temperature value and the current temperature value.

[0032] From the above description, it can be known that by obtaining the temperature values ​​before and after hibernation, it is determined whether the temperature change during hibernation is normal, so as to confirm whether there is any abnormality in the temperature data during hibernation.

[0033] The embodiment of the present invention provides a temperature warning method and terminal based on power control, which can be applied to a device that uses CT power to supply power. According to the temperature change, early warning reporting is performed to solve the problem of untimely data reporting. The following is an explanation through a specific embodiment: Please refer to Figure 1 to Figure 2 , Embodiment 1 of the present invention: A temperature early warning method based on electric energy control comprises the following steps: S1. Obtain energy storage voltage value and temperature data.

[0034] Specifically, the energy storage voltage value includes a historical voltage value and a current voltage value.

[0035] In S1: obtaining the energy storage voltage value includes: S11, obtaining the historical voltage value before the sleep state and the current voltage value after the sleep state.

[0036] S12. Obtain a primary-side current value according to the historical voltage value and the current voltage value.

[0037] S13, determining whether the primary side current value meets the preset current limit, if so, executing step S2; otherwise, executing step S4.

[0038] In S1: obtaining temperature data includes: S14, obtaining the historical temperature value before hibernation and the current temperature value after hibernation.

[0039] S15 calculates the temperature change rate according to the historical temperature value and the current temperature value.

[0040] In some embodiments, the S15 is specifically: ; Among them, K t is the temperature change rate, Temp1 is the historical temperature value before sleep, Temp2 is the current voltage value after sleep, T w is the actual working cycle.

[0041] S2. Determine whether the energy storage voltage value and the temperature data meet the preset warning conditions; if so, execute step S3; otherwise, execute step S4.

[0042] In an optional implementation, the temperature data includes a current temperature value and a temperature change rate, and S2 includes: S21. Obtain a preset voltage threshold, a preset temperature threshold, and a preset temperature change threshold.

[0043] 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.

[0044] In an 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; Then the S22 includes: S221, determining whether the energy storage voltage value is greater than a first voltage value; S222: If the energy storage voltage value is greater than the first voltage value, a first temperature value and a 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, it is determined that a preset warning condition is met.

[0045] S223. If the energy storage voltage value is not greater than the first voltage value, determine whether the energy storage voltage value is greater than or equal to the second voltage value. If so, 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, determine that the preset warning conditions are met.

[0046] It should be noted that if the first voltage value is greater than the second voltage value, 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; otherwise, 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. In this way, the warning error caused by abnormal temperature change rate but the temperature has not reached the level that affects the safety of the equipment is avoided.

[0047] In some embodiments, the first voltage value is 5V, the second voltage value is 4V; the first change value is 1°C / minute, the first temperature value is 50°C; the second change value is 3°C / minute, the second temperature value is 70°C.

[0048] It should be noted that the energy storage voltage values ​​are all current voltage values.

[0049] That is, when the energy storage voltage value is greater than the first voltage value, and 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.

[0050] When the energy storage voltage value is not greater than the first voltage value and greater than the second voltage value, and 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.

[0051] When the energy storage voltage value, the current temperature value or the temperature change rate does not exceed the corresponding threshold value, step S4 is executed.

[0052] In some embodiments, when the energy storage voltage value U>5V, the temperature change rate ≥1°C / minute, and the current temperature value Temp2 ≥50°C are satisfied at the same time, step S3 is executed.

[0053] In some embodiments, when the energy storage voltage value 5V≥U≥4V, the temperature change rate≥3°C / minute, and the current temperature value Temp2≥70°C are satisfied at the same time, step S3 is executed.

[0054] In some embodiments, when the energy storage voltage value U<4V, step S4 is executed.

[0055] S3. Directly report the current temperature value and adjust the working cycle according to the energy storage voltage value.

[0056] In S3: adjusting the working cycle according to the energy storage voltage value includes: S31. Obtaining cycle compensation coefficients corresponding to different energy storage voltage values, calculating a compensation cycle according to the cycle compensation coefficients, and adjusting the working cycle according to the compensation cycle.

[0057] It should be noted that the cycle compensation coefficient corresponding to a high energy storage voltage value is low, and the cycle compensation coefficient corresponding to a low energy storage voltage value is high. Since a high energy storage voltage value indicates a high electric energy, the electric energy remaining after the data is reported is greater than the electric energy remaining when the energy storage voltage value is low. Therefore, before the next wireless data reporting, the sleep time (i.e., charging time) required when the energy storage voltage value is high is less than the sleep time (charging time) required when the energy storage voltage value is low. The S31 is specifically: the actual working cycle T w = basic working cycle T' + basic working cycle T' × cycle compensation coefficient.

[0058] In some embodiments, when the energy storage voltage value U>5V, the corresponding cycle compensation coefficient is 0.1, and when the energy storage voltage value 5V≥U≥4V, the corresponding cycle compensation coefficient is 0.3.

[0059] S4. Obtain the current working cycle, and report the current temperature value according to the working cycle.

[0060] In some embodiments, the S4 includes: S41, obtaining the current working cycle and the total sleep time, and determining whether the total sleep time is greater than or equal to the working cycle, if so, executing steps S42 to S43; otherwise, executing step S1; S42: Report the current temperature value and clear the total sleep time.

[0061] S43. Adjust the working cycle according to the primary side current value.

[0062] It should be noted that since each sleep cycle is a fixed value, the determination of whether to perform data reporting is based on the relationship between the total sleep time and the working cycle, so that the device sleep time (charging time) can be extended or shortened synchronously with the working cycle.

[0063] Please refer to Figures 2 to 3 , Embodiment 2 of the present invention: The difference between this embodiment and the first embodiment is that: the specific implementation of step S43 is limited, that is, the following steps A110 to A114, such as Figure 3 shown.

[0064] A temperature early warning method based on electric energy control comprises the following steps: If the device is powered on for the first time, the current working mode defaults to low power consumption mode, and the current actual working cycle defaults to 60 seconds.

[0065] Step A1, obtaining the historical voltage value V1 and the historical temperature value Temp1 before sleep, the current voltage value V2 and the current temperature value Temp2 after sleep, and the sleep period T s .

[0066] Step A2: Calculate the temperature change rate K based on the historical temperature value Temp1 and the current temperature value Temp2 t ; Step A3: According to the historical voltage value V1, the current voltage value V2 and the sleep period T s Get the charging rate K c ; In this embodiment, A3 is specifically: ; Among them, K c is the charging rate, V1 is the historical voltage value before sleep, V2 is the current voltage value after sleep, T s For the sleep cycle.

[0067] Step A4: according to the charging rate K c Calculate the current primary current value I p ; In this embodiment, A3 is specifically: I p =C×K c ×K i ; Among them, I p is the primary current value, C is the capacitance value of the energy storage module, K i is the power-taking coefficient of the CT power-taking module. Specifically, , I1 represents the average value of the primary side current provided by the CT power module, and I2 represents the average value of the secondary side current provided by the CT power module.

[0068] Step A5: Get the current actual working cycle T w ; Step A6: According to the sleep period T s Get the current total sleep time T sum .

[0069] Step A7, determine whether the current working mode is the balanced mode, if so, execute steps A80 to A84; otherwise, execute step A9.

[0070] Step A80, determine whether the current voltage value V2 is greater than the first voltage value 5V, if so, execute step A81; otherwise, execute step A82; Step A81: Obtain a first change value of 1°C / minute, a first temperature value of 50°C, and determine the temperature change rate K t Is it greater than or equal to 1°C / minute, and is the current temperature value Temp2 greater than or equal to 50°C? If so, execute step A84; otherwise, execute step A9.

[0071] Step A82, determine whether the current voltage value V2 is greater than or equal to the second voltage value 4V, if so, execute step A83; otherwise, execute step A9; Step A83: Obtain the second change value as 3°C / minute, the second temperature value as 70°C, and determine the temperature change rate K t Is it greater than or equal to 3°C / minute, and is the current temperature value Temp2 greater than or equal to 70°C? If so, execute step A84; otherwise, execute step A9.

[0072] Step A84, directly wirelessly report the current temperature value, and obtain the cycle compensation coefficient corresponding to the current voltage value V2 (if the current voltage value V2>5V, the cycle compensation coefficient obtained is 0.1; if the current voltage value 5V≥V2≥4V, the cycle compensation coefficient obtained is 0.3); obtain the working cycle corresponding to the current working mode as the basic working cycle T', calculate the compensation cycle according to 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 .

[0073] It should be noted that if step A84 is executed, the current actual working cycle described in step A9 is the adjusted actual working cycle T w .

[0074] Step A9: Determine the total duration of the current sleep time T sum Is it greater than or equal to the current actual working cycle T w If yes, execute step A10; otherwise, return to execute step A1.

[0075] Step A10: wirelessly report the current temperature value and the current total sleep time T sum Clear to zero and execute steps A110-A114.

[0076] Step A110: Determine the primary current value I p Is it greater than the preset threshold 50A? If so, execute step A111; otherwise, execute step A112.

[0077] Step A111, switch the current working mode to the high-performance mode, obtain the preset working cycle 30s of the high-performance mode as the basic working cycle T', and return to execute step A1.

[0078] Step A112: Determine the primary current value I p Is it greater than or equal to the first current limit 5A? If so, execute step A113; otherwise, execute step A114.

[0079] Step A113: Switch the current working mode to the balanced mode, and adjust the current value I p The first dynamic working period T1 of the balanced mode is obtained as the basic working period T', and the process returns to step A1.

[0080] In this embodiment, the primary side current value I p The first dynamic working cycle T1 of the balanced mode is obtained as follows: .

[0081] Step A114: switch the current working mode to the low power mode, and adjust the current value according to the primary current value I p The second dynamic working period T2 of the low power consumption mode is obtained as the basic working period T', and the process returns to step A1.

[0082] In this embodiment, the primary side current value I p The second dynamic working cycle T2 of the low power consumption mode is obtained as follows: T2=-100×I p +800.

[0083] That is, when the primary current value I p When >50A, the current working mode switches to high performance mode; When 50A≥primary current value I p When ≥5A, the current working mode switches to balanced mode; When the primary current value I p When <5A, the current working mode switches to low power mode.

[0084] Embodiment 3 of the present invention: The difference between this embodiment and the first embodiment is that another specific implementation method of step S2 is defined.

[0085] In this embodiment, the temperature data includes the current temperature value, and S2 includes: S21. Obtain a preset voltage threshold and a preset temperature threshold.

[0086] S22: When the energy storage voltage value and the current temperature value are both greater than the preset voltage threshold and the preset temperature threshold, it is determined that the preset warning condition is met.

[0087] In an optional implementation, the preset voltage threshold includes a first voltage value, and the preset temperature threshold includes a first temperature value, then S22 includes: S221, determine whether the energy storage voltage value is greater than the first voltage value, if so, execute step S222; otherwise, execute step S4.

[0088] S222: Determine whether the current voltage value is greater than the first temperature value, and if so, determine that a preset warning condition is met.

[0089] The S3 includes: S31. Obtain a preset cycle compensation coefficient, calculate a compensation cycle according to the cycle compensation coefficient, and adjust the working cycle according to the compensation cycle.

[0090] In an optional implementation, the preset voltage includes a first voltage value and a second voltage value, and the preset temperature threshold includes a first temperature value, then S22 includes: S221.

[0106] Please refer to Figure 4 , Embodiment 5 of the present invention: A temperature warning terminal based on electric energy control includes a memory 301, a processor 302, and a computer program stored in the memory 301 and running on the processor 302.

[0107] In summary, the present invention provides a temperature warning method and terminal based on electric energy control. By acquiring the energy storage voltage value and temperature data, it is determined whether the temperature change of the current detected device has problems such as abnormal rise or fall. When it is detected that the energy storage voltage value and temperature data meet the preset warning conditions, there is no need to wait for the next data reporting cycle, and the current temperature value can be directly reported. In this way, the problem of excessive temperature caused by too long data reporting cycle and untimely data reporting can be avoided. For abnormal temperature, data reporting can be performed in advance to realize 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 electric energy consumed by the data reporting during the sleep period, and avoids power failure and shutdown caused by insufficient power. At the same time, data is reported through the relative relationship between the total sleep time and the working cycle, and then the working cycle is intelligently adjusted according to the fluctuation of the primary side current value, so that the primary side current value can indirectly adjust the sleep cycle, prevent the problem of power failure and shutdown caused by the fluctuation of the primary side current value, and make its working mode more flexible, which can be applied to more severe working conditions.
