Various embodiments of the method of the present invention are presented in terms of the above-described hardware architecture.
Referring to fig. 2, in a first embodiment of the method for determining the start-up of a microwave oven according to the present invention, the method for determining the start-up of a microwave oven includes the steps of:
step S10, obtaining active power of a cycle at the total electric meter, and taking the obtained cycle as a first cycle;
in the scheme, the terminal can obtain the active power of each cycle of the alternating current signal at the inlet of the main electric meter in real time. The specific steps of obtaining the active power of the cycle are that the terminal calculates the total number of sampling points of a cycle according to a preset sampling frequency and the frequency of an alternating current signal at an inlet of a total electric meter, for example, the preset sampling frequency is 1600Hz, the frequency of the alternating current signal is 50Hz, then the number of sampling points of a cycle is 1600/50-32, then the terminal can collect the voltage signal and the current signal at the inlet of the total electric meter according to the preset sampling frequency through an external voltage sensor and a built-in current sensor or an internal voltage sensor and an internal current sensor, when the voltage signal and the current signal of the sampling points of a cycle are continuously collected, for example, 32 voltage signals and corresponding current signals are continuously collected, the active power of a cycle is calculated according to the 32 continuous voltage signals and corresponding current signals, and then the next group of continuous 32 voltage signals and current signals are continuously collected, the same calculation method calculates the active power of the next cycle.
When active power of a cycle is acquired, the acquired cycle is taken as a first cycle, namely, an initial point for judging the starting of the microwave oven.
Step S20, obtaining the active power of the first cycle and the second cycle after the first cycle;
after the terminal acquires the first cycle, the terminal will continue to acquire the active power of two cycles after the first cycle, that is, the active power of the first cycle and the active power of the second cycle.
Step S30, judging whether a first preset condition is met according to the active power of the first cycle, the active power of the first cycle and the active power of the second cycle after the first cycle;
because can embody two characteristics on active power when microwave oven starts, the first stage is the power lifting, can produce the load of a similar pulse impact, and this stage time is short, and the impact amplitude is big, and active power can be quick suddenly rise by a wide margin and fall by a wide margin that immediately starts immediately, and the time span that the pulse rises and the time span that the pulse descends all are 1 cycle. The step is to determine whether the 3 cycles meet the characteristics of the first stage by using the characteristics of the first stage to obtain the active power of the consecutive 3 cycles, that is, to determine whether the first preset condition is met according to the active power of the first cycle, the active power of the first cycle and the active power of the second cycle after the first cycle.
Further, step S30 includes:
step S31, obtaining a difference value between the active power of the first cycle after the first cycle and the active power of the first cycle after the first cycle as a first power increment according to the active power of the first cycle and the active power of the first cycle after the first cycle;
step S32, obtaining a difference between the active power of the first cycle after the first cycle and the active power of the second cycle after the first cycle as a second power increment, according to the active power of the first cycle after the first cycle and the active power of the second cycle after the first cycle;
step S33, determining whether the first power increment is greater than a first preset increment threshold and the second power increment is greater than a second preset increment threshold; if the first power increment is greater than the first preset increment threshold and the second power increment is greater than the second preset increment threshold, executing step S34; if the first power increment is less than or equal to the first preset increment threshold and/or the second power increment is less than or equal to the second preset increment threshold, executing step S35;
step S34, determining that a first preset condition is met;
in step S35, it is determined that the first preset condition is not satisfied.
After obtaining the active power of the first cycle, the active power of the first cycle after the first cycle, and the active power of the second cycle, the terminal subtracts the active power of the first cycle from the active power of the first cycle after the first cycle, and obtains a first power increment, that is, a pulse rising amplitude in the first stage. And subtracting the active power of the second cycle after the first cycle from the active power of the first cycle after the first cycle to obtain a second power increment, namely the pulse falling amplitude in the first stage. Then, comparing the obtained first power increment with a first preset increment threshold value, and comparing the obtained second power increment with a second preset increment threshold value, wherein the first preset increment threshold value is preferably 450w, and the second preset increment threshold value is preferably 250 w; if the first power increment is larger than the first preset increment threshold and the second power increment is larger than the second preset increment threshold, the terminal can determine that the first preset condition is met, namely the characteristic of the first stage is met.
It should be noted that, in the process of determining whether the first preset condition is met, the first increment may be obtained first, and it is determined whether the first power increment is greater than a first preset increment threshold first, if the determination result is less than or equal to the first preset increment threshold, it is directly determined that the first preset condition is not met, if the determination result is greater than the first preset increment threshold, it is determined that the second power increment is performed, if the determination result is less than or equal to the second preset increment threshold, it is determined that the first preset condition is not met, and if the determination result is greater than the first preset condition, it is determined that the first preset condition is met.
Further, step S30 includes:
step S31, obtaining a difference value between the active power of the first cycle after the first cycle and the active power of the first cycle after the first cycle as a first power increment according to the active power of the first cycle and the active power of the first cycle after the first cycle;
step S32, obtaining a difference between the active power of the first cycle after the first cycle and the active power of the second cycle after the first cycle as a second power increment, according to the active power of the first cycle after the first cycle and the active power of the second cycle after the first cycle;
step S36, obtaining the difference value between the active power of the second cycle after the first cycle and the active power of the first cycle as a third power increment according to the active power of the first cycle and the active power of the second cycle after the first cycle;
step S37, determining whether the first power increment is greater than a first preset increment threshold, whether the second power increment is greater than a second preset increment threshold, and whether the third power increment is greater than a third preset increment threshold; if the first power increment is greater than the first preset increment threshold, the second power increment is greater than the second preset increment threshold, and the third power increment is greater than the third preset increment threshold, then step S34 is executed; if the first power increment is less than or equal to at least one of the first preset increment threshold, the second power increment is less than or equal to the second preset increment threshold, and the third power increment is less than or equal to the third preset increment threshold, executing step S35;
step S34, determining that a first preset condition is met;
in step S35, it is determined that the first preset condition is not satisfied.
Since the determination of the first phase may be affected by noise, in order to determine the first phase more accurately, in addition to obtaining the first power increment, i.e., the pulse rising amplitude in the first phase, and the second power increment, i.e., the pulse falling amplitude in the first phase, the active power of the first cycle is subtracted from the active power of the second cycle after the first cycle to obtain the third power increment, i.e., the pulse rising amplitude in the first phase. Comparing the obtained first power increment with a first preset increment threshold, comparing the obtained second power increment with a second preset increment threshold, and comparing the obtained third power increment with a third preset increment threshold, wherein the third preset increment threshold is preferably 450 w; if the first power increment is larger than the first preset increment threshold, the second power increment is larger than the second preset increment threshold, and the third power increment is larger than the third preset increment threshold, the terminal can determine that the first preset condition is met, that is, the characteristic of the first stage is met. And if at least one of the first power increment is smaller than or equal to a first preset increment threshold, the second power increment is smaller than or equal to a second preset increment threshold and the third power increment is smaller than or equal to a third preset increment threshold appears in the comparison result, judging that the first-stage characteristic is not satisfied.
It should be noted that, in the process of determining whether the first preset condition is met, the first increment may be obtained first, and it is determined first whether the first power increment is greater than a first preset increment threshold, if the determination result is less than or equal to the first preset condition, it is directly determined that the first preset condition is not met, if the determination result is greater than the first preset increment threshold, it is determined that the second power increment and the third power increment are determined, if the determination result is that the second power increment is less than or equal to the second preset increment threshold and/or that the third power increment is less than or equal to the third preset increment threshold, it is determined that the first preset condition is not met, and if the determination result is that the second power increment is greater than the second preset increment threshold and the third power increment is greater than the third preset increment threshold, it is determined that the first preset condition is met.
Step S40, when the first preset condition is satisfied, taking the cycle after the first cycle and separated from the first cycle by a first preset number as the second cycle;
step S50, obtaining the average active power of the first preset number of cycles and the average active power of the second preset number of cycles;
when the first preset condition is met, namely the first stage characteristic is determined to be met, whether the second stage characteristic is met or not is judged, a plurality of cycles are arranged between the second stage and the first stage, and the second stage characteristic mainly comprises that the active power uplift is generally in the form of slow increase of the active power and longer time span, and is similar to a slope-type curve. In order to determine whether the second-stage characteristic is satisfied, specifically, the active power of each cycle after the first cycle is continuously acquired until a cycle after the first cycle and separated from the first cycle by a first preset number is acquired as a second cycle, and the active power of the second cycle is acquired, where the first preset number may be any one of values from 60 to 100, and is preferably 80, and for example, an 81 th cycle after the first cycle is taken as the second cycle.
After the second cycle is determined, the active power of each cycle after the second cycle is continuously obtained until the active power of each cycle in a second preset number of cycles after the second cycle is obtained, and the active power of each cycle in a first second preset number of cycles of the second cycle is obtained from the cycles obtained before the second cycle, wherein the second preset number may be any one of values from 4 to 10, and is preferably 5, then the average active power of a later second preset number of cycles of the second cycle is calculated according to the active power of each cycle in the later second preset number of cycles of the second cycle, and the average active power of an earlier second preset number of cycles of the second cycle is calculated according to the active power of each cycle in the earlier second preset number of cycles of the second cycle.
Step S60, judging whether a second preset condition is met according to the average active power of the first preset number of cycles and the average active power of the second preset number of cycles;
after the terminal obtains the average active power of the first preset number of cycles of the second cycle and the average active power of the second preset number of cycles, the step is to determine whether the second cycle belongs to the middle point of the climbing curve in the second stage by using the characteristics of the second stage according to the average active power of the first preset number of cycles and the average active power of the second preset number of cycles, namely, whether the second preset condition is met is judged according to the average active power of the first preset number of cycles and the average active power of the second preset number of cycles.
Specifically, step S60 includes:
step S61, obtaining the difference value between the average active power of the later second preset number of cycles and the average active power of the earlier second preset number of cycles of the second cycle as a fourth power increment according to the average active power of the earlier second preset number of cycles and the average active power of the later second preset number of cycles;
step S62, judging whether the fourth power increment is larger than a fourth preset increment threshold value; if yes, go to step S63; if not, go to step S64;
step S63, determining whether a second preset condition is satisfied;
step S64, determining that the second preset condition is not satisfied
The terminal subtracts the average active power of the second preset number of cycles after the second cycle from the average active power of the second preset number of cycles before the second cycle to obtain a fourth power increment, and compares the obtained fourth power increment with a fourth preset increment threshold, wherein the fourth preset increment threshold is preferably 30 w; and if the fourth power increment is larger than a fourth preset increment threshold, determining that the second preset condition is met, and if the fourth power increment is smaller than or equal to the fourth preset increment threshold, determining that the second preset condition is not met.
Step S70, when a second preset condition is met, adding 1 to the effective frequency, and judging whether the current effective frequency is larger than a preset threshold value; if yes, go to step S80; if not, go to step S90;
step S80, clearing the effective frequency and determining the start of the microwave oven;
step S90 is executed to update the first cycle after the second cycle to the second cycle, and the process returns to step S50.
When a second preset condition is met, determining that the currently selected second cycle has the characteristics of the cycle in the climbing curve in the second stage, adding 1 to the effective cycle, before the first second cycle is judged, the effective cycle is 0, after each second cycle is judged to be in accordance with the characteristics of the cycle in the climbing curve, judging whether the current effective cycle is greater than a preset threshold value or not, if the current effective cycle is greater than the preset threshold value, namely the duration time of the climbing trend reaches the preset time, determining that the second stage exists, namely determining that the microwave oven is started, and clearing the effective cycle to be zero so as to facilitate the subsequent judgment of starting the microwave oven. If the current effective cycle number is not greater than the preset threshold, a cycle after the second cycle determined to belong to the cycle feature in the climbing curve is updated to the second cycle, and the step S50 is executed again, that is, the process of determining whether the second cycle has the cycle feature in the climbing curve before is repeated.
The method comprises the steps of judging whether the active power change trend of three cycles is the pulse form of a first stage of microwave oven starting according to the active power of three continuous adjacent cycles, obtaining the difference value between the average active power of a cycle with a preset number before and the average active power of a cycle with a preset number after the active power change trend of the first stage of microwave oven starting is determined to be consistent with the active power change trend of the first stage of microwave oven starting and then after a plurality of cycles are separated, judging whether the power change trend of the cycle nearby is the active power change curve of a second stage of the microwave oven according to the difference value, if yes, adding 1 to the number of effective cycles consistent with the second stage, continuously judging the next cycle, and determining that the microwave oven is started until the number of effective cycles consistent with the second stage reaches a preset threshold value continuously. When the microwave oven is started, if other electric appliances are overlapped, although the increment of the second-order lifting active power changes at a certain moment, the change trend of the 'climbing' of the active power always exists, and the influence of other electric appliances on the second-order judgment can be eliminated just by judging the change trend of the active power based on the average active power of a plurality of cycles and judging the second-order climbing time of the microwave oven in the judgment process of the second-order microwave oven, so that the judgment accuracy of the starting of the microwave oven is improved.
Further, referring to fig. 3, fig. 3 is a diagram illustrating a second embodiment of the method for determining the start-up of a microwave oven according to the first embodiment of the method for determining the start-up of a microwave oven of the present application, and in this embodiment, after step S30, the method further includes:
step S41, when the first preset condition is not satisfied, updating the first cycle after the first cycle to the first cycle, and returning to execute step S20.
When it is determined that the first cycle, the three consecutive cycles formed by the first cycle and the second cycle after the first cycle do not conform to the first-stage characteristics, the first cycle after the first cycle is taken as a new first cycle, and the process returns to step S20 to determine whether the three consecutive cycles formed by the new first cycle, the first cycle after the new first cycle and the second cycle conform to the first-stage characteristics. For example, in a cycle sequence, it is determined that three consecutive cycles consisting of the first cycle, the second cycle, and the third cycle do not match the first-stage feature, and it is determined whether three consecutive cycles consisting of the second cycle, the third cycle, and the fourth cycle match the first-stage feature, and if not, it is determined whether three consecutive cycles consisting of the third cycle, the fourth cycle, and the fifth cycle match the first-stage feature, and if it is not determined that three cycles matching the first-stage feature exist, it is determined until three cycles matching the first-stage feature are found.
Further, referring to fig. 4, fig. 4 is a third embodiment of the method for determining the start-up of a microwave oven according to the first embodiment and the second embodiment of the method for determining the start-up of a microwave oven of the present application, and in the present embodiment, after step S60, the method further includes:
step S71, when the second preset condition is not satisfied, judging whether the number of the cycles between the second cycle and the first cycle is less than the sum of the third preset number and the current effective cycle; if yes, go to step S72; if not, go to step S73;
step S72, updating the first cycle after the second cycle to be the second cycle, and returning to execute step S50;
and step S73, clearing the effective frequency, taking the first cycle after the second cycle as the first cycle, acquiring the active power of the first cycle, and returning to execute step S20.
When it is determined that the currently selected second cycle does not satisfy the second preset condition, it is determined whether the number of cycles between the currently selected second cycle and the first cycle is smaller than the sum of the third preset number and the current effective cycle, and if the number of cycles between the currently selected second cycle and the first cycle is greater than or equal to the sum of the third preset number and the current effective cycle, the determination of the second stage characteristics is immediately stopped, the current effective cycle is cleared, the currently selected first cycle after the second cycle is used as the first cycle, the active power of the first cycle is obtained, and then the step S20 is executed to restart the determination of the first stage. If the number of the currently selected second cycle and the first cycle is smaller than the sum of the third preset number and the current effective cycle, updating the currently selected second cycle to be the second cycle, and returning to the step S50. For example, assume that the second predetermined number is 80 and the third predetermined number is 115. If the number of the currently selected second cycles is 112, and the currently selected second cycles is determined not to satisfy the characteristics of the second-stage hill-climbing cancellation cycle, the current effective cycle number is 2, and at this time, 112 is smaller than 115+2, the next cycle of the currently selected second cycles is used as a new second cycle, and the process returns to continuously determine whether the new second cycle meets the second-stage characteristics. If the number of the cycles between the currently selected second cycle and the first cycle is 117, and the currently selected second cycle is determined not to satisfy the characteristics of the cycle in the hill climbing cancellation in the second stage, the current effective cycle is 2, and at this time, 117 is equal to 115+2, the determination of the second stage is stopped, and the determination of the first stage is restarted by taking the next cycle as the first cycle without continuing to determine whether the next cycle conforms to the characteristics of the second stage.
