Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric energy control, and particularly relates to an electric energy control method of a CT power taking device and a terminal. BACKGROUND

[0002] At first, a hardware electric energy management scheme is used in a CT power taking (Current Transformer, CT) device to realize stable operation of the device, and the working principle is as follows: the electric energy obtained by the CT power taking module is stored in an energy storage module, the energy storage module is controlled by a voltage monitoring module to output externally, and the electric energy is ensured to be sufficient when the device works, and the device is not prone to power failure. However, after the device starts working, especially when a wireless message is transmitted, the power consumption of the entire device greatly increases, and the electric energy in the energy storage module is quickly consumed, the device is powered off, and then the device is started again when the energy storage module is fully charged, forming an intermittent working mechanism.

[0003] Based on the defects of the hardware electric energy management scheme, the current CT power taking device is provided with a software electric energy management scheme, the device is periodically put into sleep and charged when starting to work, and then a wireless report is made, so that the device can be stably and on-line operated. However, the existing software electric energy management scheme usually sets the working period of the CT power taking device manually, and cannot intelligently adjust the working period of the device, resulting in poor flexibility of the device in different scenes. SUMMARY

[0004] The technical problem to be solved by the present application is to provide an electric energy control method of a CT power taking device and a terminal, which intelligently adjusts the working period of the CT power taking device according to the primary side current value, and improves the use flexibility of the CT power taking device.

[0005] In order to solve the above technical problems, the technical scheme adopted by the present application is as follows:

[0006] An electric energy control method of a CT power taking device, comprising the steps of:

[0007] obtaining a primary side current value of the CT power taking device;

[0008] determining whether the primary side current value is greater than a first preset threshold value, if the primary side current value is greater than the first preset threshold value, obtaining a preset working period as a current working period;

[0009] if the primary side current value is less than or equal to the first preset threshold value, obtaining a dynamic working period as the current working period according to the primary side current value.

[0010] In order to solve the above technical problems, another technical scheme adopted by the present application is as follows:

[0011] The application discloses a power control terminal of a CT power taking device, which comprises a memory, a processor and a computer program stored in the memory and running on the processor.

[0012] The primary side current value of the CT power taking device is acquired.

[0013] It is judged whether the primary side current value is greater than a first preset threshold value, and if yes, a preset working period is acquired as a current working period.

[0014] If no, a dynamic working period is acquired as the current working period according to the primary side current value.

[0015] The application has the beneficial effects that when the primary side current value is greater than the first preset threshold value, it indicates that the current primary side current is large, and the device power can support real-time online work without sleep charging, so a fixed preset working period is directly acquired as the current working period to report data in real time. When the primary side current value is not greater than the first preset threshold value, it indicates that the current primary side current is small, and the device power cannot support real-time online work, and sleep charging is needed, so the current working period is intelligently adjusted according to the size of the current primary side current to reasonably delay the sleep time length to ensure sufficient power. Compared with a fixed period set by manual setting or software default, the application intelligently adjusts the device working period according to the primary side current value to ensure the device power and improve the use flexibility of the CT power taking device.

[0022] The technical content, purposes and effects of the application are described in detail in the following combined with the embodiments and the drawings.

[0023] Please refer to Figure 1 The embodiment of the present application provides a kind of electric energy control method of CT power taking equipment, comprising the steps of:

[0024] Obtain the primary side current value of the CT power taking equipment;

[0025] Determine whether the primary side current value is greater than the first preset threshold value, if greater than the first preset threshold value, obtain the preset working period as the current working period;

[0026] If less than or equal to the first preset threshold value, obtain the dynamic working period as the current working period according to the primary side current value.

[0027] From the above description, the beneficial effects of the present application are that when the primary side current value is greater than the first preset threshold value, it indicates that the current primary side current is large, and its equipment electric energy can support real-time online work without hibernation charging, so the fixed preset working period is directly obtained as the current working period, and the data is reported in real time. When the primary side current value is not greater than the first preset threshold value, it indicates that the current primary side current is small, and its equipment electric energy cannot support real-time online work, and needs to hibernate and charge, so the current working period is intelligently adjusted according to the size of the current primary side current, and the hibernation time is reasonably delayed to ensure sufficient electric energy. Compared with the fixed period set by artificial or software default, the present application intelligently adjusts the equipment working period according to the primary side current value, ensures the equipment electric energy, and improves the use flexibility of the CT power taking equipment.

[0028] Further, the obtaining of the primary side current value of the CT power taking equipment comprises:

[0029] Obtain the hibernation period of the CT power taking equipment and the historical voltage value before hibernation;

[0030] Record the current voltage value of the CT power taking equipment every interval of the hibernation period;

[0031] Obtain the charging rate according to the historical voltage value, the current voltage value and the hibernation period;

[0032] Calculate the current primary side current value according to the charging rate.

[0033] From the above description, by obtaining the historical voltage value before hibernation and the current voltage value after hibernation, the charging rate can be calculated, and the charging rate and the primary side current value are in linear relationship, so the corresponding voltage values before and after each hibernation are obtained, the primary side current value is detected, and it is judged whether the current value can maintain the device power consumption. In this way, the detection element is avoided in the device, the device structure is simplified, the current detection is realized, and the overall energy consumption of the device is reduced.

[0034] Further, after obtaining the primary side current value of the CT power taking device, the method further comprises:

[0035] obtaining a current working period and a current total sleep duration of the CT power taking device;

[0036] determining whether the current total sleep duration is greater than or equal to the current working period;

[0037] if yes, reporting data and clearing the current total sleep duration.

[0038] As can be seen from the above description, since the sleep period each time is a fixed value, and the current working period is adjusted according to the size of the primary side current value, whether to report data is selected by determining whether the current total sleep duration is greater than the current working period, so that the device sleep period is indirectly related to the primary side current value; that is, the sleep charging time of the CT power taking device is extended or reduced through the primary side current value, the sleep period is intelligently adjusted, and the effect of ensuring the power of the device is achieved.

[0039] Further, the method further comprises:

[0040] determining whether an emergency warning event occurs in the CT power taking device;

[0041] if yes, adjusting the current working period according to the type of the emergency warning event.

[0042] As can be seen from the above description, if the CT power taking device occurs an emergency warning event, the current working period is adjusted, so as to avoid the problem that the data reporting is not timely due to the too low primary side current value, and improve the use flexibility of the CT power taking device.

[0043] Further, the CT power taking device is used for monitoring environmental data;

[0044] The determination of whether an emergency warning event occurs in the CT power taking device comprises:

[0045] obtaining an energy storage voltage value and environmental data of the CT power taking device;

[0046] determining whether the energy storage voltage value and the environmental data are all greater than a second preset threshold, and if yes, reporting the current environmental monitoring value in an emergency;

[0047] The adjustment of the current working period according to the type of the emergency warning event comprises:

[0048] obtaining the event type of the emergency warning event according to the energy storage voltage value;

[0049] and obtaining an adjustment coefficient corresponding to the event type, and calculating a compensation period of the working period based on the adjustment coefficient;

[0050] adjust the current working period according to the compensation period.

[0051] As can be seen from the above description, the adjustment coefficient of the working period is obtained according to the energy storage voltage value, and the effect of intelligently adjusting the working period according to the device electric energy is realized. Meanwhile, in the case that the energy storage voltage value and the environmental data are both greater than the second preset threshold, the current data is only urgently reported when the energy storage voltage value and the environmental data are both greater than the second preset threshold, which not only ensures that the device electric energy will not be powered off after the emergency report, but also avoids the problem of long sleep period causing the data reporting to be not timely.

[0052] Further, the current working period is obtained as the dynamic working period according to the primary side current value, which includes:

[0053] determining whether the primary side current value is greater than or equal to a first current limit, if yes, switching the current working mode to an equalization mode, and obtaining the first dynamic working period of the equalization mode as the current working period according to the primary side current value;

[0054] otherwise, switching the current working mode to a low-power consumption mode, and obtaining the second dynamic working period of the low-power consumption mode as the current working period according to the primary side current value.

[0055] As can be seen from the above description, when the primary side current value is greater than or equal to the first current limit, it indicates that the primary side current value is insufficient to maintain the current working period, and after reporting the data once, the electric energy will decrease, so it is necessary to reduce the working period according to the primary side current value, and periodically sleep to reduce the power consumption and supplement the electric energy. When the primary side current value is less than the first current limit, it indicates that the primary side current value is very small, and the sleep period needs to be extended to further reduce the power consumption. In this way, the working period is dynamically adjusted according to the primary side current value, the power consumption is reduced, and the problems of data reporting not timely and power off are avoided.

[0056] Further, it further includes:

[0057] if the current sleep total duration is less than the current working period, returning to execute the step of obtaining the primary side current value of the CT power taking device.

[0058] As can be seen from the above description, after the device is powered on, it is determined whether the data reporting mode of the current working mode is reasonable according to the current working period and the current sleep total duration. When the sleep total duration is greater than the working period, it indicates that the sleep time is too long, and there is a risk of data reporting not timely, and then it is determined whether the working mode needs to be switched according to the size of the primary side current value. Compared with switching the working mode according to the preset period, the present application uses the relationship between the sleep duration and the working period as the prerequisite condition for switching the mode, which is beneficial to real-time sensing of the sleep period of the device and improves the flexibility of switching the working mode.

[0059] Further, the preset working period is obtained as the current working period.

[0060] The current working mode is switched to the high-performance mode, and the preset working period of the high-performance mode is obtained as the current working period.

[0061] From the above description, when the primary side current value is greater than the first preset threshold, it indicates that the primary side current value is large enough, and the current value can provide sufficient power support for the device, so that the device can work online in real time. The working period of the high-performance mode is set in advance to avoid adjusting the working period according to the primary side current to cause the data reporting to be too frequent.

[0062] Please refer to Figure 4 Another embodiment of the present application provides an electric energy control terminal of a CT power taking device, which comprises 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:

[0063] The primary side current value of the CT power taking device is obtained.

[0064] It is judged whether the primary side current value is greater than a first preset threshold. If the primary side current value is greater than the first preset threshold, a preset working period is obtained as the current working period.

[0065] If the primary side current value is less than or equal to the first preset threshold, a dynamic working period is obtained as the current working period according to the primary side current value.

[0066] From the above description, the beneficial effects of the present application are as follows: when the primary side current value is greater than the first preset threshold, it indicates that the current primary side current is large, and the device power can support real-time online work without sleep charging. Therefore, a fixed preset working period is directly obtained as the current working period to report data in real time. When the primary side current value is not greater than the first preset threshold, it indicates that the current primary side current is small, and the device power cannot support real-time online work, and sleep charging is needed. Therefore, the current working period is intelligently adjusted according to the size of the current primary side current to reasonably delay the sleep time length to ensure sufficient power. Compared with the fixed period set by manual setting or software default, the present application intelligently adjusts the device working period according to the primary side current value to ensure the device power and improve the use flexibility of the CT power taking device.

[0067] Further, the primary side current value of the CT power taking device is obtained by:

[0068] The sleep period of the CT power taking device and the historical voltage value before sleep are obtained.

[0069] Record the current voltage value of the CT power taking device every interval of the sleep period;

[0070] Obtain the charging rate according to the historical voltage value, the current voltage value and the sleep period;

[0071] Calculate the current primary side current value according to the charging rate.

[0072] As can be seen from the above description, the charging rate can be calculated by obtaining the historical voltage value before sleep and the current voltage value after sleep, and the charging rate and the primary side current value are in linear relationship, so the primary side current value can be detected by obtaining the corresponding voltage value before and after each sleep, thereby determining whether the current current value can maintain the power consumption of the device. In this way, the current detection is realized while simplifying the structure of the device by avoiding adding detection elements in the device, thereby reducing the overall energy consumption of the device.

[0073] The embodiment of the application provides a power control method and a terminal of a CT power taking device, which can be applied to a device powered by a CT power taking device, intelligently adjusts the working period of the CT power taking device according to the size of the primary side current, solves the problem of untimely data reporting, avoids the risk of power-off shutdown, and the following will be described through specific embodiments:

[0074] Please refer to Figures 1 to 2 Embodiment one of the application:

[0076] S11, obtaining a primary side current value of the CT power taking device;

[0077] Specifically, the S1 comprises:

[0078] S111, obtaining a sleep period of the CT power taking device and a historical voltage value before sleep;

[0079] It should be noted that the historical voltage value and the current voltage value are specifically the voltage value of the energy storage module.

[0080] In some embodiments, if the device is powered on for the first time, the current working mode is the low-power-consumption module by default, and the current working period module is 60 seconds.

[0081] S112, recording the current voltage value of the CT power taking device every interval of the sleep period;

[0082] S113, obtaining a charging rate according to the historical voltage value, the current voltage value and the sleep period;

[0083] In some embodiments, the S113 specifically comprises:

[0084]

[0085] wherein, K c is the charging rate, V1 is the historical voltage value before hibernation, V2 is the current voltage value after hibernation, T s is the hibernation period.

[0087] In some embodiments, the S114 is specifically:

[0088] I p =C×K c ×K i ;

[0089] wherein, I p is the primary side 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 taking module, and I2 represents the average value of the secondary side current provided by the CT power taking module.

[0090] It should be noted that the hibernation period is the hibernation time, that is, the time interval between the end of the last device entering hibernation and the start of the current device entering hibernation.

[0091] The S11 further comprises:

[0092] S101, obtaining the current working period and the current total hibernation time of the CT power taking device;

[0093] S102, judging whether the current total hibernation time is greater than or equal to the current working period, if yes, executing step S103; otherwise, executing step S11.

[0094] S103, reporting data and clearing the current total hibernation time.

[0095] It should be noted that the working period is the working time, that is, the time interval between the end of the device entering the working mode from hibernation and the next time the device enters hibernation from the working mode.

[0096] In some embodiments, the hibernation period is accumulated after each hibernation is completed to obtain the current total hibernation time. It should be noted that the hibernation period is a preset fixed value.

[0097] The method further comprises:

[0101] S2011, acquiring an energy storage voltage value of the CT power taking device and environmental data;

[0102] S2012, judging whether the energy storage voltage value and the environmental data are greater than a second preset threshold value, if yes, reporting current environmental monitoring values in an emergency.

[0103] It should be noted that the energy storage voltage value is a voltage value of an energy storage module.

[0104] The S202 comprises:

[0105] S2021, acquiring an event type of the emergency early warning event according to the energy storage voltage value;

[0106] S2022, acquiring an adjustment coefficient corresponding to the event type, and calculating a compensation period of the working period based on the adjustment coefficient;

[0107] S2023, adjusting the current working period according to the compensation period.

[0108] It should be noted that the S201 further comprises: judging whether a current working mode is a balance mode, if yes, executing the step S201, otherwise returning to execute the step S101. In this way, the problem that the sleep time is too long in the prior art, the temperature changes greatly during the sleep, and the data cannot be reported in time is avoided. Since the data is reported in advance, the power consumption is caused, and therefore the current working period needs to be adjusted after the data reporting is completed to delay the sleep time and supplement the power.

[0109] S21, judging whether the primary side current value is greater than a first preset threshold value, if greater than the first preset threshold value, executing the step S31, if less than or equal to the preset threshold value, executing the step S41;

[0110] In some embodiments, the preset threshold value is 50A.

[0111] S31, acquiring a preset working period as a current working period;

[0112] Specifically, the S31 comprises:

[0113] S311, switching a current working mode to a high performance mode, and acquiring a preset working period of the high performance mode as a current working period.

[0114] In some embodiments, the sleep period is 10 seconds by default, and the preset working period of the high-performance mode is 30 seconds to avoid too frequent data reporting of the device.

[0115] S41, obtaining a dynamic working period as a current working period according to the primary-side current value.

[0116] Specifically, the S41 includes:

[0117] S411, determining whether the primary-side current value is greater than or equal to a first current limit, and if yes, performing step S412; otherwise, performing step S413.

[0118] In some embodiments, the first current limit is 5 A, i.e., 50 A >= primary-side current value I p >= 5 A, the current working mode is switched to the balanced mode; the primary-side current value I p < 5 A, the current working mode is switched to the low-power-consumption mode.

[0119] S412, switching the current working mode to the balanced mode, and obtaining a first dynamic working period of the balanced mode as the current working period according to the primary-side current value.

[0120] In some embodiments, the first dynamic working period of the balanced mode obtained according to the primary-side current value is specifically:

[0121]

[0122] wherein I p is the primary-side current value.

[0123] S413, switching the current working mode to the low-power-consumption mode, and obtaining a second dynamic working period of the low-power-consumption mode as the current working period according to the primary-side current value.

[0124] In some embodiments, the second dynamic working period of the low-power-consumption mode obtained according to the primary-side current value is specifically:

[0125] T1 = -100 x I p + 800;

[0126] wherein I p is the primary-side current value.

[0127] It should be noted that since the sleep duration is a fixed value each time, while the current working cycle is adjusted based on the primary current value, data reporting is based on the relative relationship between the total sleep duration and the working cycle, thus indirectly linking the device's sleep cycle to the primary current value. Specifically, if the primary current value is high, the corresponding working cycle is short; for example, in this embodiment, when the primary current value is 51A, the corresponding working cycle is 30 seconds. With a fixed sleep duration of 10 seconds, data can be reported after 3 sleep cycles. If the primary current value is low, the corresponding working cycle is long, and data is reported after an increase in the number of sleep cycles (equivalent to increasing charging time and replenishing power); for example, in this embodiment, when the primary current value is 30A, the corresponding working cycle is 50 seconds. With a fixed sleep duration of 10 seconds, data can be reported after 5 sleep cycles.

[0128] Please refer to Figure 3 Embodiment 2 of the present invention:

[0129] The difference between this embodiment and Embodiment 1 is that it specifies the specific implementation of steps S201-S202, namely steps A80 to A84 below, as follows: Figure 3 As shown.

[0130] In this embodiment, the environmental data is the ambient temperature value.

[0135] 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.

[0136] It should be noted that the work cycle obtained for each work mode is the basic work cycle, and the actual work cycle T is... w = Basic work cycle + compensation cycle.

[0146] In the embodiment, the event type of the emergency warning event is specifically: a temperature threshold type of environmental data; wherein the temperature threshold includes a temperature change rate threshold and a temperature kurtosis threshold, and the event type of the emergency warning event is obtained according to the current voltage value, which is specifically:

[0147] Step A82, obtaining a first change rate threshold of 1℃ / min and a first temperature peak of 50℃, judging whether a temperature change rate K t is greater than or equal to 1℃ / min and whether a current temperature value Temp2 is greater than or equal to 50℃, if yes, executing step A84; otherwise, executing a step of judging whether the current total sleep duration is greater than or equal to the actual working period.

[0148] Step A83, obtaining a second change rate threshold of 3℃ / min and a second temperature peak of 70℃, and judging whether the temperature change rate K twhether the current temperature value Temp2 is greater than or equal to 70℃, if yes, step A84 is executed; otherwise, whether the current total sleep duration is greater than or equal to the actual working period is judged.

[0149] Step A84, the current temperature value is urgently reported, the adjustment coefficient corresponding to the current voltage value V2 is obtained (i.e. 0.1 or 0.3), the working period corresponding to the current working mode is obtained as the basic working period T', the compensation period is calculated according to the adjustment coefficient (0.1 or 0.3) and the basic working period, and the adjusted actual working period T is obtained w = basic working period T' + compensation period T b .

[0150] That is, when the current voltage value V2> 5V, the temperature change rate ≥ 1℃ / min, the current temperature value ≥ 50℃, and the three conditions are met at the same time, the current temperature value is urgently reported wirelessly, and the actual working period T w is increased by 0.1×basic working period T';

[0151] When the current voltage value 5V≥V2≥4V, the temperature change rate ≥ 3℃ / min, the current temperature value ≥ 70℃, and the three conditions are met at the same time, the current temperature value is urgently reported wirelessly, and the actual working period T w is increased by 0.3×basic working period T';

[0152] When the current voltage value V2<4V, whether the current total sleep duration is greater than or equal to the actual working period is judged.

[0153] Please refer to Figure 4 , embodiment three of the present application:

Even if primary side current is lower than 5A, sleep cycle can be further prolonged according to primary side current, to ensure that electric energy can still support stable operation of device. At the same time, when primary side current value is high, data is reported frequently, and when primary side current value is low, sleep duration is delayed, which greatly improves the utilization rate of primary side electric energy.

[0156] The above is only an embodiment of the application, and does not limit the patent scope of the application, and any equivalent transformation or direct or indirect application in related technical field using the content of the specification and drawings is also included in the patent protection scope of the application.
