Description

Technical Field

[0001] The present invention relates to the field of energy efficiency testing, and in particular to an artificial intelligence-based stove energy efficiency testing method and system. Background Art

[0002] Traditional methods of testing the energy efficiency of stoves often rely on manual operation, which is not only time-consuming but also prone to errors. Artificial intelligence systems can monitor the operating status of stoves in real time and quickly analyze large amounts of data. With the continuous advancement of stove technology, new energy efficiency testing standards and methods are also constantly being refined, and the division of energy efficiency levels is more stringent. In the energy efficiency test, it is necessary to exclude the influence of irrelevant factors as much as possible to ensure the accuracy of the energy efficiency test.

[0003] The prior art, such as announcement number: CN111695227B, is a method for evaluating the heating uniformity of a stove. An infrared camera is arranged above the stove, and the position of the infrared camera is adjusted so that the center position of the infrared image collected by the infrared camera coincides with the center of the stove gas burner. A frying pan is placed on the stove, and the stove burner is turned on. The infrared camera takes an infrared image, and the infrared temperature images at three consecutive moments are processed to obtain a stove heating uniformity parameter TDF based on temperature and a stove heating uniformity parameter QDF based on heating intensity.

[0004] The prior art, such as the announcement number: CN106547998B, is a gas stove optimization design evaluation method and its test system, including the following steps: ① typical sample selection; ② establishment of sample three-dimensional geometric model; ③ sample experimental test research: including a. establishment of experimental system for testing, b. simulation of the sample based on experimental test data as boundary conditions; ④ judgment and correction of simulation results based on measured data; ⑤ application of verified gas flow and combustion model to all experimental samples for verification test and simulation; ⑥ use of simulation to guide design. The test experimental system used in this method consists of a gas supply part, a gas appliance performance test part and a control host with a signal conversion module.

[0005] Based on the above scheme, it can be seen that the existing technology often focuses on analyzing the process of stove testing through simulation or image analysis when testing stoves. In actual testing, only relying on images to test stoves usually leads to inaccurate test results due to too thin data. The accuracy of simulation testing depends on the complexity of the simulation conditions. If the simulation conditions are simplified too much or the parameters are not set accurately, it usually leads to a large deviation between the simulation results and the actual situation. Therefore, it is necessary to fully consider the factors that will affect the accuracy of stove test results in actual testing. Summary of the invention

[0047] See also Figure 1 As shown, an embodiment of the present invention provides a method for testing energy efficiency of a cooker based on artificial intelligence, comprising: S1. Before testing, retrieve the original power parameters at the power interface of the electromagnetic cooker to be tested, compare them with the rated power parameters, and obtain the rated difference result of the power interface.

[0048] The original power supply parameters at the power supply interface of the electromagnetic cooker to be tested are retrieved and compared with the rated power supply parameters. The specific process is as follows: Before the test period, a test load adjustment device is connected to the power interface of the electromagnetic cooker to be tested, and the load of the device is adjusted to the total circuit component load of the electromagnetic cooker to be tested to perform a power supply test.

[0049] The original power supply parameters at the power supply interface of the electromagnetic cooker to be tested include sequential input voltage, sequential input current, sequential power supply frequency and sequential power factor.

[0050] The rated power supply parameters include rated input voltage, rated input current, rated power supply frequency and rated power factor.

[0051] The original power supply parameters refer to the power supply input characteristic parameters dynamically collected over time during the test process, reflecting the real-time electrical status of the induction cooker when it is actually working.

[0052] The timing input voltage refers to the instantaneous value sequence of voltage collected in real time at the power interface (unit: V). It reflects the dynamic fluctuation characteristics of the power supply voltage. A high-precision voltage sensor (in the embodiment of the present invention, a Hall effect sensor) is used to record the waveform through a high-speed data acquisition card.

[0053] Sequential input current refers to the instantaneous current value sequence (unit: A) collected in real time at the power interface. It is used to characterize the dynamic changes and harmonic characteristics of the load. Harmonic analysis is performed using a current transformer in conjunction with a power analyzer.

[0054] Sequential power frequency refers to the instantaneous value sequence of power supply frequency measured in real time (unit: Hz). It is used to evaluate the stability of power grid frequency. It is recorded in real time by frequency counter using FFT spectrum analysis method.

[0055] The time series power factor refers to the power factor value sequence calculated in real time, which is used to reflect the effective utilization rate of electric energy.

[0056] The original power supply parameters at the power supply interface of the electromagnetic cooker to be tested are compared with the rated power supply parameters to obtain the voltage deviation rate, current deviation rate, frequency offset and power factor deviation value at the power supply interface of the electromagnetic cooker to be tested.

[0057] The voltage deviation rate indicates the ratio of the absolute value of the difference between the timing input voltage and the rated voltage to the rated voltage as a percentage. The current deviation rate indicates the ratio of the absolute value of the difference between the timing input current and the rated current to the rated current as a percentage. The frequency offset indicates the absolute difference between the timing power supply frequency and the rated frequency. The power factor deviation value indicates the absolute difference between the timing power factor and the rated power factor.

[0058] The obtaining of the rated difference result of the power interface specifically includes: The voltage deviation rate, current deviation rate, frequency offset and power factor deviation value at the power interface of the electromagnetic cooker to be tested are comprehensively processed and analyzed to obtain the rated difference result at the power interface of the electromagnetic cooker to be tested. The specific processing method is as follows: ; Where A is the rated difference evaluation value at the power interface of the electromagnetic cooker to be tested, is the voltage deviation rate at the power interface of the electromagnetic cooker to be tested, is the current deviation rate at the power interface of the electromagnetic cooker to be tested, is the frequency offset at the power interface of the electromagnetic cooker to be tested, is the power factor deviation value at the power interface of the electromagnetic cooker to be tested, is the voltage deviation rate weight factor, is the current deviation rate weight factor, is the frequency offset weight factor, is the weight factor of the power factor deviation value at the power interface of the electromagnetic cooker to be tested.

[0059] It should be noted that the voltage deviation rate weight factor, current deviation rate weight factor, frequency offset weight factor and power factor deviation value weight factor all have a value range between 0 and 1 and satisfy The voltage deviation rate weight factor is an influencing factor of the voltage deviation rate pre-stored in the built-in database of the artificial intelligence data processing terminal, indicating the degree of influence of the voltage deviation rate on the rated difference evaluation value at the power interface of the electromagnetic cooker to be tested; the current deviation rate weight factor is an influencing factor of the current deviation rate pre-stored in the built-in database of the artificial intelligence data processing terminal, indicating the degree of influence of the current deviation rate on the rated difference evaluation value at the power interface of the electromagnetic cooker to be tested; the frequency offset weight factor is an influencing factor of the frequency offset pre-stored in the built-in database of the artificial intelligence data processing terminal, indicating the degree of influence of the frequency offset on the rated difference evaluation value at the power interface of the electromagnetic cooker to be tested; the power factor deviation value The weight factor is an influencing factor of the power factor deviation value pre-stored in the built-in database of the artificial intelligence data processing terminal, which indicates the degree of influence of the power factor deviation value on the rated difference evaluation value at the power interface of the electromagnetic cooker to be tested. When used, it is directly extracted from the built-in database of the artificial intelligence data processing terminal. For example, after the voltage deviation rate, current deviation rate, frequency offset and power factor deviation value at the power interface of the electromagnetic cooker to be tested are input into the preset mapping set in the built-in database of the artificial intelligence data processing terminal, the voltage deviation rate weight factor, current deviation rate weight factor, frequency offset weight factor and power factor deviation value weight factor at the power interface of the electromagnetic cooker to be tested are obtained, and the corresponding mapping relationship is one-to-one.

[0060] It should also be noted that there is a certain correlation between the voltage deviation rate, current deviation rate, frequency offset and power factor deviation value at the power interface of the electromagnetic cooker to be tested. The voltage deviation rate affects the current deviation rate. If the voltage increases, the current usually decreases for a constant power load, and vice versa. For nonlinear loads, voltage fluctuations usually cause distortion of the current waveform, thereby increasing the current deviation rate. Frequency offset refers to the difference between the actual power frequency and the nominal grid frequency. Frequency offset usually affects the operating efficiency of the motor, thereby indirectly affecting the stability of current and voltage. The power factor deviation value is related to the phase difference between voltage and current. If there is a phase difference between voltage and current, the power factor will decrease. Waveform distortion of voltage and current (caused by nonlinear loads) will cause a decrease in power factor. Voltage deviation and frequency offset usually affect the operating state of the motor, thereby affecting its power factor.

[0061] The rated difference result at the power interface of the electromagnetic cooker to be tested includes an eliminateable difference and an irremovable difference.

[0062] The rated difference evaluation value at the power interface of the electromagnetic cooker to be tested is compared and analyzed with the rated difference evaluation threshold value pre-stored in the built-in database of the artificial intelligence data processing terminal. If the rated difference evaluation value at the power interface of the electromagnetic cooker to be tested is greater than or equal to the rated difference evaluation threshold value, the rated difference result at the power interface of the electromagnetic cooker to be tested is determined to be an irremovable difference; if the rated difference evaluation value at the power interface of the electromagnetic cooker to be tested is less than the rated difference evaluation threshold value, the rated difference result at the power interface of the electromagnetic cooker to be tested is determined to be an removable difference.

[0063] The removable differences are differences that can be analyzed, processed and corrected by the artificial intelligence data processing terminal involved in the embodiment of the present invention.

[0064] The irreconcilable differences are differences that cannot be analyzed, processed, or corrected by the artificial intelligence data processing terminal involved in the embodiment of the present invention.

[0065] If the rated difference result at the power interface of the electromagnetic cooker to be tested is that the difference can be eliminated, the voltage deviation rate, current deviation rate, frequency offset and power factor deviation value at the power interface of the electromagnetic cooker to be tested are mapped and matched with the voltage deviation correction factor, current deviation rate correction factor, frequency offset correction factor and power factor deviation correction factor corresponding to the voltage deviation rate interval, current deviation rate interval, frequency offset interval and power factor deviation value interval pre-stored in the built-in database of the artificial intelligence data processing terminal, respectively, to obtain the voltage deviation correction factor, current deviation rate correction factor, frequency offset correction factor and power factor deviation correction factor at the power interface of the electromagnetic cooker to be tested, and import them into the artificial intelligence data processing terminal, and comprehensively process them into the rated difference correction factor at the power interface of the electromagnetic cooker to be tested. The specific processing process includes: ; in, is the rated difference correction factor at the power interface of the electromagnetic cooker to be tested, is the voltage deviation correction factor at the power interface of the electromagnetic cooker to be tested, is the current deviation rate correction factor at the power interface of the electromagnetic cooker to be tested, is the frequency offset correction factor at the power interface of the electromagnetic cooker to be tested, is the power factor deviation correction factor at the power interface of the electromagnetic cooker to be tested, is the voltage deviation correction weight, is the current deviation correction weight, is the frequency offset correction weight, is the power factor deviation correction weight.

When used, it is directly extracted from the built-in database of the artificial intelligence data processing terminal. For example, the voltage deviation rate weight factor, current deviation rate weight factor, frequency offset weight factor and power factor deviation value weight factor at the power interface of the electromagnetic cooker to be tested are input into the preset mapping set in the built-in database of the artificial intelligence data processing terminal to obtain the voltage deviation correction weight, current deviation correction weight, frequency offset correction weight and power factor deviation correction weight at the power interface of the electromagnetic cooker to be tested, and the corresponding mapping relationship is one-to-one.

[0067] If the rated difference result at the power interface of the electromagnetic cooker to be tested is an irreconcilable difference, the rated difference result at the power interface of the electromagnetic cooker to be tested is sent to the display area of ​​the artificial intelligence data processing terminal to remind the user to replace the power supply.
