[0044] When the production management platform monitors the production of any transformer production line, it generates a supervision instruction and sends the supervision instruction to the production information unit. After receiving the supervision instruction, the production information unit immediately collects the processing data of the transformer production line and the historical basic information of the facilities, and sends the processing data and the historical basic information to the energy efficiency division unit and the facility factor unit respectively.

[0052] In the embodiment of the present invention, the product quality coefficient represents the proportion of the number of qualified products in the total number of products produced by the transformer production line in the sub-time period. It should be noted that the transformer production line is analyzed from the perspective of product qualification rate to ensure low-consumption and high-efficiency production of the transformer production line;

[0053] After receiving the historical basic information, the facility factor unit immediately performs a facility interference assessment operation on the historical basic information, so as to analyze it from the perspective of the impact of the facilities in the transformer production line. On the one hand, it helps to understand the risk situation of each facility, and on the other hand, it helps to understand the impact of the facilities on the operational stability of the transformer production line. The specific facility interference assessment operation process is as follows:

[0054] Obtain the historical basic information of each facility in the transformer production line within the time threshold, the historical basic information includes the use time, parts information and maintenance management coefficient, the use time indicates the time from the time when each facility in the transformer production line starts to be put into use to the current time, the parts information indicates the total number of times the parts of the facility are replaced, the maintenance management coefficient indicates the product of the average maintenance interval time and the value corresponding to the number of overheating operations, the number of overheating operations indicates the number of times the time corresponding to the operating temperature of the facility exceeding the preset operating temperature threshold is greater than the number corresponding to the preset time threshold, mark the facilities in the transformer production line as n, n is a natural number greater than zero, and label the use time, parts information and maintenance management coefficient as SCn, LJn and WGn respectively;

[0056] If the ratio between the damage assessment coefficient Sn and the preset damage assessment coefficient threshold is less than 1, the corresponding facility is determined to be a stable facility;

[0057] If the ratio between the damage assessment coefficient Sn and the preset damage assessment coefficient threshold is greater than or equal to 1, the corresponding facility is determined to be a risk facility, and the ratio between the number of risk facilities and the number of stable facilities is obtained. The ratio between the number of risk facilities and the number of stable facilities is set as the facility risk coefficient SF, and the stable facilities and risk facilities are sent to the management response unit at the same time. After receiving the stable facilities and risk facilities, the management response unit immediately marks the numbers corresponding to the stable facilities and risk facilities respectively, so as to supervise the stable facilities and risk facilities respectively and conduct subsequent maintenance adjustments;

[0058] It should be noted that the larger the value of the facility risk factor SF, the greater the risk of abnormal operation of the transformer production line.

It should be noted that the high-efficiency risk rate is an influencing parameter reflecting the stability of high-efficiency production of the transformer production line;

[0062] The potential interference coefficient of the transformer production line within the time threshold is obtained. The potential interference coefficient represents the product value obtained by multiplying the fault frequency and the total number of faults of the transformer production line after data normalization. It should be noted that the potential interference coefficient is an influencing parameter reflecting the efficient production stability of the transformer production line;

[0063] The high efficiency risk rate and potential interference coefficient are labeled as GF and QG respectively, and the high efficiency risk rate GF, the potential interference coefficient QG and the facility risk coefficient SF are substituted into the formula R = [(GF + QG) × (a1 + a2) + SF × a3] × a4 to obtain the production line stability risk coefficient, wherein a1, a2 and a3 are the preset proportional factor coefficients of the high efficiency risk rate GF, the potential interference coefficient QG and the facility risk coefficient SF respectively. The proportional factor coefficient is used to correct the deviation of various parameters in the formula calculation process, so as to make the calculation result more accurate. a1, a2 and a3 are all greater than zero, a4 is the preset correction factor coefficient, and the value is 2.191. R is the production line stability risk coefficient. The production line stability risk coefficient R is compared with the preset production line stability risk coefficient threshold value stored in the internal input:

[0066] The optimal production unit is used to perform optimal production line recommendation supervision analysis, so as to reasonably produce transformers to achieve low-consumption, high-efficiency and stable production, which helps to save production costs and improve production efficiency. The specific production line optimal recommendation supervision analysis process is as follows:

The intersection of set A and set D is obtained, and the transformer production line corresponding to the intersection of set A and set D is marked as an efficient and risky production line.

The intersection of set B and set D is obtained, and the transformer production line corresponding to the intersection of set B and set D is marked as an inefficient and risky production line. The efficient and stable production line, the efficient and risky production line, the inefficient and stable production line, and the inefficient and risky production line are sent to the management response unit. After receiving the efficient and stable production line, the efficient and risky production line, the inefficient and stable production line, and the inefficient and risky production line, the management response unit immediately marks the corresponding preset warning text on the numbers of the efficient and stable production line, the efficient and risky production line, the inefficient and stable production line, and the inefficient and risky production line on the display panel, so as to intuitively understand the division of the transformer production line, and at the same time facilitate reasonable and targeted management of the transformer production line.

[0069] At the same time, the production evaluation coefficient and the production line stability risk coefficient R corresponding to the efficient and stable production line are obtained, the production evaluation coefficient is labeled as SX, and the production evaluation coefficient SX and the production line stability risk coefficient R are substituted into the formula TJ = (SX×R×v1) 2 Obtain the production line recommended evaluation coefficient, where v1 is the preset influencing factor coefficient, v1 is greater than zero, TJ is the production line recommended evaluation coefficient, obtain the minimum value of the production line recommended evaluation coefficient TJ, mark the efficient and stable production line corresponding to the minimum value of the production line recommended evaluation coefficient TJ as the best recommended production line, and send the best recommended production line to the management response unit. After receiving the best recommended production line, the management response unit immediately displays the number corresponding to the best recommended production line, so as to produce the transformer to achieve low-consumption, high-efficiency and stable production, thereby helping to save production costs and improve production efficiency;

[0070] In summary, the present invention analyzes from the perspective of energy efficiency and stability of the transformer production line to achieve low-consumption, high-efficiency and stable production of the transformer, which helps to save production costs and improve production efficiency, that is, to perform processing supervision division evaluation analysis on the processing data, that is, to analyze the transformer production line from the perspective of product quality and energy consumption to ensure low-consumption and high-efficiency production of the transformer production line, and to perform operation stability supervision division analysis from the perspective of stability, so as to divide the transformer production line based on dynamic stability to understand the stability of the transformer production line, and to analyze in combination with the operating influencing factors of the facilities in the transformer production line.
