[0029] It is represented by the weight ratio corresponding to the preset electric steam cabinet inverter output frequency obtained from the database, which represents the numerical value of the influence of the electric steam cabinet inverter output frequency on the electric steam cabinet temperature accuracy evaluation coefficient. When used, the weight ratio corresponding to the electric steam cabinet inverter output frequency can be directly obtained from the database, and the corresponding relationship can be a pre-set mapping relationship. For example, the electric steam cabinet inverter output frequency and the weight ratio corresponding to the electric steam cabinet inverter output frequency preset in the database form a mapping set, and the weight ratio corresponding to the electric steam cabinet inverter output frequency is obtained according to the electric steam cabinet inverter output frequency input mapping set, and the mapping relationship can be one-to-one or many-to-one.

[0030] It is represented by the weight ratio corresponding to the preset electric steam cabinet temperature obtained from the database, which represents the numerical value of the influence of the electric steam cabinet temperature on the electric steam cabinet temperature accuracy assessment coefficient. When used, the weight ratio corresponding to the electric steam cabinet temperature can be directly obtained from the database, and the corresponding relationship can be a pre-set mapping relationship. For example, the electric steam cabinet temperature and the weight ratio corresponding to the electric steam cabinet temperature preset in the database form a mapping set, and the weight ratio corresponding to the electric steam cabinet temperature is obtained according to the electric steam cabinet temperature input mapping set, wherein the mapping relationship can be one-to-one or many-to-one.

[0032] The parameter data of the temperature accuracy of the electric steam cabinet include the output frequency of the electric steam cabinet inverter, the temperature of the electric steam cabinet, the temperature change speed of the electric steam cabinet, the standard value of the output frequency of the electric steam cabinet inverter, the standard value of the electric steam cabinet temperature and the standard value of the temperature change speed of the electric steam cabinet.

[0033] The frequency of the inverter output end of the electric steam cabinet is obtained through a frequency sensor or a Hall sensor, that is, the output frequency of the inverter of the electric steam cabinet is obtained. The standard value of the inverter output frequency of the electric steam cabinet in the current use mode is obtained from the design manual of the electric steam cabinet. The temperature of the electric steam cabinet at the target monitoring position is obtained through the built-in temperature sensor of the electric steam cabinet, that is, the temperature of the electric steam cabinet. The temperature of the electric steam cabinet at the target monitoring position in the current use mode is obtained from the design manual of the electric steam cabinet, that is, the standard value of the temperature of the electric steam cabinet. The temperature at a preset time point before the time monitoring point is obtained through the temperature sensor, the temperature is subtracted from the electric steam cabinet temperature and divided by the time difference between the time monitoring point and the preset time point to obtain the temperature heating speed, that is, the temperature change speed of the electric steam cabinet.

[0034] The greater the output frequency of the electric steam cabinet inverter, the higher the electric steam cabinet temperature reached in the same time period, and the faster the electric steam cabinet temperature changes; the smaller the output frequency of the electric steam cabinet inverter, the lower the electric steam cabinet temperature reached in the same time period, and the slower the electric steam cabinet temperature changes. The higher or lower the electric steam cabinet temperature and the greater the difference from the electric steam cabinet temperature standard value, the less accurate the electric steam cabinet is in inverter frequency modulation and temperature control. In the algorithm of this embodiment, the electric steam cabinet temperature accuracy parameter data is nonlinearly transformed by using a hyperbolic cosine function, which smoothes the influence of abnormal values ​​in the electric steam cabinet temperature accuracy parameter data on the electric steam cabinet temperature accuracy evaluation coefficient, so that the obtained electric steam cabinet temperature accuracy evaluation coefficient is more accurate.

[0038] In this embodiment, the specific method for obtaining the electric steam cabinet humidity accuracy evaluation index is as follows: setting multiple time monitoring points and numbering the time monitoring points; performing multiple data acquisitions at the time monitoring points and numbering the data acquisition times; setting multiple target monitoring positions and numbering the target monitoring positions; obtaining the electric steam cabinet humidity accuracy parameter data; obtaining the preset electric steam cabinet temperature, electric steam cabinet humidity and electric steam cabinet humidity change speed corresponding weight ratio from the database; ; In the formula, Expressed as The humidity accuracy evaluation index of the electric steam cabinet at each time monitoring point is: , It is the number of the time monitoring point. Expressed as the total number of time monitoring points, Indicated as the first The target monitoring position is The first time monitoring point The temperature of the electric steam cabinet when the data was acquired.

It is expressed as the weight ratio of the humidity of the electric steam cabinet in the evaluation index of the humidity accuracy of the electric steam cabinet. It is expressed as the weight ratio of the humidity change rate of the electric steam cabinet in the humidity accuracy evaluation index of the electric steam cabinet.

[0039] It is represented by the weight ratio corresponding to the preset electric steam cabinet temperature obtained from the database, which represents the numerical value of the influence of the electric steam cabinet temperature on the electric steam cabinet humidity accuracy evaluation index. When used, the weight ratio corresponding to the electric steam cabinet temperature can be directly obtained from the database, and the corresponding relationship can be a pre-set mapping relationship. For example, the electric steam cabinet temperature and the weight ratio corresponding to the electric steam cabinet temperature preset in the database form a mapping set, and the weight ratio corresponding to the electric steam cabinet temperature is obtained according to the electric steam cabinet temperature input mapping set, wherein the mapping relationship can be one-to-one or many-to-one.

[0040] It is represented by the weight ratio corresponding to the preset electric steam cabinet humidity obtained from the database, which represents the numerical value of the influence of the electric steam cabinet humidity on the electric steam cabinet humidity accuracy evaluation index. When used, the weight ratio corresponding to the electric steam cabinet humidity can be directly obtained from the database, and the corresponding relationship can be a pre-set mapping relationship. For example, the electric steam cabinet humidity and the weight ratio corresponding to the electric steam cabinet humidity preset in the database form a mapping set, and the weight ratio corresponding to the electric steam cabinet humidity is obtained according to the electric steam cabinet humidity input mapping set, wherein the mapping relationship can be one-to-one or many-to-one.

[0041] It is represented by the weight ratio corresponding to the preset electric steam cabinet humidity change speed obtained from the database, which represents the numerical value of the influence of the electric steam cabinet humidity change speed on the electric steam cabinet humidity accuracy evaluation index. When used, the weight ratio corresponding to the electric steam cabinet humidity change speed can be directly obtained from the database, and the corresponding relationship can be a pre-set mapping relationship. For example, the electric steam cabinet humidity change speed and the weight ratio corresponding to the electric steam cabinet humidity change speed preset in the database form a mapping set, and the weight ratio corresponding to the electric steam cabinet humidity change speed is obtained according to the electric steam cabinet humidity change speed input mapping set, wherein the mapping relationship can be one-to-one or many-to-one.

[0042] The parameter data of the electric steam cabinet humidity accuracy include the electric steam cabinet temperature, the electric steam cabinet humidity, the electric steam cabinet humidity change rate, the electric steam cabinet temperature standard value, the electric steam cabinet humidity reference value and the electric steam cabinet humidity change rate reference value.

[0043] The humidity of the electric steam cabinet at the target monitoring position in the current usage mode is obtained through the built-in humidity sensor of the electric steam cabinet, that is, the humidity of the electric steam cabinet. The humidity of the electric steam cabinet at the target monitoring position in the current usage mode is obtained through the design manual of the electric steam cabinet, that is, the humidity reference value of the electric steam cabinet. The humidity at a preset time point before the time monitoring point is obtained through the humidity sensor, the humidity is subtracted from the humidity of the electric steam cabinet and divided by the time difference between the time monitoring point and the preset time point to obtain the humidity change rate, that is, the humidity change rate of the electric steam cabinet. Similarly, the reference value of the humidity change rate of the electric steam cabinet in the current usage mode is obtained from the design manual of the electric steam cabinet.

[0044] The higher the temperature of the electric steam cabinet or the more the humidification device outputs, the faster the water evaporates under the same other conditions, resulting in a higher humidity in the electric steam cabinet and a faster humidity change rate in the electric steam cabinet; the lower the temperature of the electric steam cabinet or the smaller the output of the humidification device, the slower the water evaporates under the same other conditions, resulting in a lower humidity in the electric steam cabinet and a slower humidity change rate in the electric steam cabinet. The higher the humidity of the electric steam cabinet or the lower the difference from the humidity reference value of the electric steam cabinet, the less accurate the humidity adjustment of the electric steam cabinet is. In the algorithm of this embodiment, the influence of the maximum value on the humidity accuracy evaluation index of the electric steam cabinet is smoothed by performing square root processing on the humidity accuracy parameter data of the electric steam cabinet, so that the humidity accuracy evaluation index of the electric steam cabinet is made more accurate.

[0045] Furthermore, the specific analysis process of analyzing the humidity regulation degree of the electric steamer cabinet according to the electric steamer cabinet humidity accuracy evaluation index is as follows: obtaining the electric steamer cabinet humidity accuracy evaluation index, obtaining a preset electric steamer cabinet humidity accuracy first threshold and a preset electric steamer cabinet humidity accuracy second threshold from a database; when the electric steamer cabinet humidity accuracy evaluation index is greater than the electric steamer cabinet humidity accuracy first threshold and less than the electric steamer cabinet humidity accuracy second threshold, it indicates that the humidity regulation degree of the electric steamer cabinet is normal; when the electric steamer cabinet humidity accuracy evaluation index is below the electric steamer cabinet humidity accuracy first threshold, or the electric steamer cabinet humidity accuracy evaluation index is above the electric steamer cabinet humidity accuracy second threshold, it indicates that the humidity regulation degree of the electric steamer cabinet is abnormal.

[0046] In this embodiment, when the electric steam cabinet humidity accuracy evaluation index is greater than the first electric steam cabinet humidity accuracy threshold and less than the second electric steam cabinet humidity accuracy threshold, it means that the humidity adjustment of the electric steam cabinet is very close to the humidity adjustment under the standard conditions indicated in the design specifications, indicating that the humidity adjustment degree of the electric steam cabinet is normal; when the electric steam cabinet humidity accuracy evaluation index is more below the first electric steam cabinet humidity accuracy threshold, it means that the humidity adjustment of the electric steam cabinet is lower than the humidity adjustment under the standard conditions indicated in the design specifications, or when the electric steam cabinet humidity accuracy evaluation index is more above the second electric steam cabinet humidity accuracy threshold, it means that the humidity adjustment of the electric steam cabinet is higher than the humidity adjustment under the standard conditions indicated in the design specifications, both of which indicate that the humidity adjustment degree of the electric steam cabinet is abnormal.

[0047] Furthermore, the specific analysis process of analyzing the adjustment accuracy of the electric steamer according to the adjustment parameter data of the electric steamer is as follows: according to the adjustment parameter data of the electric steamer, the temperature accuracy evaluation coefficient of the electric steamer and the humidity accuracy evaluation index of the electric steamer are obtained; according to the temperature accuracy evaluation coefficient of the electric steamer and the humidity accuracy evaluation index of the electric steamer, the adjustment accuracy evaluation index of the electric steamer is obtained, and the adjustment accuracy evaluation index of the electric steamer is used to indicate the accuracy of the electric steamer in overall adjustment; according to the adjustment accuracy evaluation index of the electric steamer, the adjustment accuracy of the electric steamer is analyzed.

[0048] Furthermore, the specific method for obtaining the electric steam cabinet adjustment accuracy evaluation index is as follows: obtaining the electric steam cabinet temperature accuracy evaluation coefficient and the electric steam cabinet humidity accuracy evaluation index; obtaining the preset electric steam cabinet temperature accuracy evaluation coefficient and the electric steam cabinet humidity accuracy evaluation index corresponding weight ratio from the database; setting multiple time monitoring points and numbering the time monitoring points; ; In the formula, Expressed as The evaluation index of the electric steam cabinet adjustment accuracy at each time monitoring point, , It is the number of the time monitoring point. Expressed as the total number of time monitoring points, Expressed as The temperature accuracy evaluation coefficient of the electric steam cabinet at each time monitoring point is: Expressed as The humidity accuracy evaluation index of the electric steam cabinet at each time monitoring point is: It is expressed as the weight ratio of the electric steam cabinet temperature accuracy assessment coefficient in the electric steam cabinet adjustment accuracy assessment index. It is expressed as the weight ratio of the electric steam cabinet humidity accuracy evaluation index in the electric steam cabinet adjustment accuracy evaluation index.

[0049] In this embodiment, It is represented by the weight ratio corresponding to the preset electric steam cabinet temperature accuracy assessment coefficient obtained from the database, which represents the numerical value of the influence of the electric steam cabinet temperature accuracy assessment coefficient on the electric steam cabinet adjustment accuracy assessment index. When used, the weight ratio corresponding to the electric steam cabinet temperature accuracy assessment coefficient can be directly obtained from the database, and the corresponding relationship can be a pre-set mapping relationship. For example, the electric steam cabinet temperature accuracy assessment coefficient and the weight ratio corresponding to the electric steam cabinet temperature accuracy assessment coefficient preset in the database form a mapping set, and the mapping set is input according to the electric steam cabinet temperature accuracy assessment coefficient to obtain the weight ratio corresponding to the electric steam cabinet temperature accuracy assessment coefficient, wherein the mapping relationship can be one-to-one or many-to-one.

[0050] It is represented by the weight ratio corresponding to the preset electric steam cabinet humidity accuracy evaluation index obtained from the database, which represents the numerical value of the influence of the electric steam cabinet humidity accuracy evaluation index on the electric steam cabinet adjustment accuracy evaluation index. When used, the weight ratio corresponding to the electric steam cabinet humidity accuracy evaluation index can be directly obtained from the database, and the corresponding relationship can be a pre-set mapping relationship. For example, the electric steam cabinet humidity accuracy evaluation index and the weight ratio corresponding to the electric steam cabinet humidity accuracy evaluation index preset in the database form a mapping set, and the mapping set is input according to the electric steam cabinet humidity accuracy evaluation index to obtain the weight ratio corresponding to the electric steam cabinet humidity accuracy evaluation index, and the mapping relationship can be a one-to-one correspondence or a many-to-one relationship.

[0051] The electric steam cabinet adjustment parameter data includes the electric steam cabinet temperature accuracy evaluation coefficient and the electric steam cabinet humidity accuracy evaluation index.

[0052] In the algorithm of this embodiment, the electric steamer adjustment accuracy evaluation index is obtained by comprehensively analyzing the electric steamer temperature accuracy evaluation coefficient and the electric steamer humidity accuracy evaluation index, so that the electric steamer adjustment accuracy evaluation index is more comprehensive and specific, and the influence of possible abnormal values ​​is smoothed by the inverse cotangent function, which is conducive to obtaining a more accurate electric steamer adjustment accuracy evaluation index. The electric steamer adjustment accuracy evaluation index can be used to more accurately analyze the electric steamer adjustment accuracy.

[0053] In a specific embodiment, Figure 2As shown, it is a curve diagram of the electric steamer adjustment accuracy evaluation index provided in the embodiment of the present application, with the electric steamer temperature accuracy evaluation coefficient as the independent variable and the electric steamer adjustment accuracy evaluation index as the dependent variable. For example, for the electric steamer at the third time monitoring point, through the increase and decrease analysis of curve one, curve two and curve three, it can be known that when the electric steamer temperature accuracy evaluation coefficient is larger, the electric steamer adjustment accuracy evaluation index is larger; when the electric steamer temperature accuracy evaluation coefficient is smaller, the electric steamer adjustment accuracy evaluation index is smaller. The statistical table of relevant data of the electric steamer adjustment accuracy evaluation index is shown in Table 1: Table 1 Statistical table of relevant data of the evaluation index of the adjustment accuracy of the electric steam cabinet When the electric steamer humidity accuracy evaluation indexes of curve 1, curve 2 and curve 3 are 1.00, 1.10 and 1.18 respectively, and other parameters are consistent, the electric steamer adjustment accuracy evaluation indexes of curve 1, curve 2 and curve 3 are 2.55, 2.78 and 2.97 respectively. It can be seen that when the electric steamer temperature accuracy evaluation coefficient is consistent with other parameters, the larger the electric steamer humidity accuracy evaluation index is, the larger the electric steamer adjustment accuracy evaluation index is.

[0054] Furthermore, the specific analysis process of analyzing the adjustment accuracy of the electric steamer according to the electric steamer adjustment accuracy evaluation index is as follows: obtaining the electric steamer adjustment accuracy evaluation index, obtaining the preset first electric steamer adjustment accuracy threshold, the second electric steamer adjustment accuracy threshold and the preset limit value from the database; when the electric steamer adjustment accuracy evaluation index is greater than the first electric steamer adjustment accuracy threshold and less than the second electric steamer adjustment accuracy threshold, it indicates that the adjustment accuracy of the electric steamer is accurate; when the difference between the electric steamer adjustment accuracy evaluation index and the first electric steamer adjustment accuracy threshold is less than the preset limit value, or the difference between the second electric steamer adjustment accuracy threshold and the electric steamer adjustment accuracy evaluation index is less than the preset limit value, it indicates that the adjustment accuracy of the electric steamer is slightly inaccurate; when in other situations, it indicates that the adjustment accuracy of the electric steamer is seriously inaccurate.

[0055] In this embodiment, when the electric steam cabinet regulation accuracy evaluation index is greater than the first electric steam cabinet regulation accuracy threshold and less than the second electric steam cabinet regulation accuracy threshold, it indicates that the regulation of the temperature and humidity of the electric steam cabinet is very close to the regulation of the temperature and humidity under the standard conditions indicated in the design specification, indicating that the regulation accuracy of the electric steam cabinet is accurate; when the difference between the electric steam cabinet regulation accuracy evaluation index and the first electric steam cabinet regulation accuracy threshold is less than a preset limit value, or the difference between the second electric steam cabinet regulation accuracy threshold and the electric steam cabinet regulation accuracy evaluation index is less than a preset limit value, it indicates that the regulation of the temperature or humidity of the electric steam cabinet is lower than the regulation of the temperature or humidity under the standard conditions indicated in the design specification by a certain gap, indicating that the regulation accuracy of the electric steam cabinet is slightly inaccurate; when in other situations, it indicates that the regulation of the temperature or humidity of the electric steam cabinet is lower than the regulation of the temperature or humidity under the standard conditions indicated in the design specification by a large gap, indicating that the regulation accuracy of the electric steam cabinet is seriously inaccurate.

[0056] Furthermore, the specific analysis process of adjusting the electric steam cabinet in combination with the adjustment accuracy of the electric steam cabinet, the temperature adjustment degree of the electric steam cabinet and the humidity adjustment degree of the electric steam cabinet is as follows: when the adjustment accuracy of the electric steam cabinet is accurate, the electric steam cabinet is not adjusted; when the adjustment accuracy of the electric steam cabinet is slightly inaccurate: when the temperature adjustment degree of the electric steam cabinet is abnormal, the output frequency of the inverter of the electric steam cabinet is fine-tuned; when the humidity adjustment degree of the electric steam cabinet is abnormal, the humidification device of the electric steam cabinet is fine-tuned; when in other situations, no adjustment is made; when the adjustment accuracy of the electric steam cabinet is seriously inaccurate: when When the temperature adjustment degree of the electric steam cabinet is abnormal, the output frequency of the electric steam cabinet inverter is adjusted. When the humidity adjustment degree of the electric steam cabinet is abnormal, the humidifying device of the electric steam cabinet is adjusted. When in other situations, no adjustment is made. After the electric steam cabinet is adjusted based on the adjustment accuracy, temperature adjustment degree and humidity adjustment degree of the electric steam cabinet, analyze again whether the electric steam cabinet needs to be adjusted. If the electric steam cabinet needs to be adjusted, continue to adjust until it is analyzed that the electric steam cabinet does not need to be adjusted. If the electric steam cabinet does not need to be adjusted, stop adjusting.

[0057] In this embodiment, when the adjustment accuracy of the electric steam cabinet is accurate, the electric steam cabinet is not adjusted; when the adjustment accuracy of the electric steam cabinet is slightly inaccurate: when the temperature adjustment degree of the electric steam cabinet is abnormal, the output frequency of the electric steam cabinet inverter is fine-tuned, when the temperature accuracy evaluation coefficient of the electric steam cabinet is below the first threshold value of the temperature accuracy of the electric steam cabinet, the output frequency of the electric steam cabinet inverter is increased, when the temperature accuracy evaluation coefficient of the electric steam cabinet is above the second threshold value of the temperature accuracy of the electric steam cabinet, the output frequency of the electric steam cabinet inverter is lowered, and when the output frequency of the electric steam cabinet inverter is increased or decreased, the adjustment range is within 5Hz each time, when the humidity adjustment degree of the electric steam cabinet is abnormal, the humidification device of the electric steam cabinet is fine-tuned, and when the humidity accuracy evaluation index of the electric steam cabinet is below the first threshold value of the humidity accuracy of the electric steam cabinet, the electric steam cabinet inverter is adjusted. Increase the humidification amount of the electric steam cabinet humidifier, or when the electric steam cabinet humidity accuracy evaluation index is above the second threshold value of the electric steam cabinet humidity accuracy, reduce the humidification amount of the electric steam cabinet humidifier, when the humidification amount of the electric steam cabinet humidifier is increased or decreased, the adjustment range is within 3% each time; when it is in other situations, no adjustment is made; when the adjustment accuracy of the electric steam cabinet is seriously inaccurate: when the temperature adjustment degree of the electric steam cabinet is abnormal, adjust the output frequency of the electric steam cabinet inverter, when the output frequency of the electric steam cabinet inverter is increased or decreased, the adjustment range is 5Hz to 10Hz each time, when the humidity adjustment degree of the electric steam cabinet is abnormal, adjust the electric steam cabinet humidifier, when the humidification amount of the electric steam cabinet humidifier is increased or decreased, the adjustment range is 3% to 7% each time; when it is in other situations, no adjustment is made.
