Determining a rotation period of each heating section combination meeting the heating conditions according to the working parameters of all the heating sections;
and determining all the heating section combination rotation modes meeting the heating conditions according to all the rotation periods.
In practical application, each time the heating section starts to stop from working, the time from working to stopping is counted to obtain working time, for example, the time from working to stopping of the heating section is 30 minutes, the obtained working time is 30 minutes, and/or each time the heating section starts to stop working, the working time is recorded as the working time of the heating section, for example, the working time of the current heating section is 0, and the working time becomes 1 after the current heating section completes the start and stop.
After the working parameters are determined, comparing the working parameters of all the heating section combinations, wherein if the working parameters of the heating section combinations A are larger than the working parameters of the heating section combinations B, the working time and/or the working times of the heating section combinations A are more, and the rotation period of the heating section combinations B can be longer than the rotation period of the heating section combinations A in the starting of the heating section;
If the working time length of the combination of the heating sections A is longer than the working time length of the combination of the heating sections B, the working time length of the combination of the heating sections B is adjusted based on the working time length of the combination of the heating sections A in the starting process of the heating sections, so that the working time length of the combination of the heating sections B is equal to or almost equal to the working time length of the combination of the heating sections A, if the working time length of the combination of the heating sections A is 5 hours, the working time length of the combination of the heating sections B is 2 hours, the combination of the heating sections B can be started for 3 hours in the starting process of the heating sections B (the starting working time length can be set by itself or preset in factory), so that the time length of the combination of the heating sections B is equal to the time length of the combination of the heating sections A, if the electric heater is still needed in a heating state in the subsequent process, the combination of the heating sections B can be continuously operated for the preset time length (if the preset time length is set to be 2 hours, the preset time length can be adjusted manually according to actual conditions or preset in factory), and then the combination of the heating sections A can be operated for the preset time length.
It should be noted that, the rotation period may be determined according to the working parameters of the heating section and the preset time length, and the working parameters are continuously taken as the working time length as an example, when the preset time length is provided, the preset time length is 2 hours, if the working time length difference between the B heating section combination and the a heating section combination is 4 hours, the B heating section combination may be rotated for 4 hours, that is, the rotation period is 4 hours at this time, when the rotation period of the B heating section combination arrives, the B heating section combination is stopped, and the a heating section combination starts to perform heating in the rotation period of 2 hours.
Similarly, the working parameters and the working time are the same in principle, and are not described in detail herein.
In some alternative implementations, the step of determining a rotation period of each of the heating segment combinations that satisfies the heating condition according to the operating parameters of all of the heating segments includes:
Calculating the sum of the working parameters of all the heating sections in each heating section combination meeting the heating conditions to obtain a sum value;
comparing the sum value of all the heating section combinations meeting the heating conditions to obtain a comparison result;
And determining the rotation period of each heating section combination meeting the heating condition according to the comparison result.
In this embodiment, the heating section combination includes at least one heating section, and when the heating section combination includes one heating section, the sum is the working parameter of the heating section, and when the heating section combination includes a plurality of heating sections, the sum is the working parameter of each heating section.
After the sum value is obtained through calculation, the sum value of each heating section combination is compared to obtain a comparison result of the size relation between the sum values, and then the sum values are sequenced according to a preset sequencing rule (see below in detail) and the size relation between the sum values, if the sum value of the A heating section combination is minimum after sequencing, the B heating section combination, the C heating section combination and the like, the maximum rotation period of the A heating section combination can be determined (see the redundant description above), and the B heating section combination and the C heating section combination are determined, so that the accurate control of the electric heater is further realized.

In addition, after the rotation mode is determined, the rotation mode can be stored so as to facilitate subsequent calling and checking, and the sorting mode of the rotation mode improves the convenience of checking and checking of operators.
In some optional implementations, in step S203, the step of alternately starting all the heating segments that meet the heating condition in the alternating manner includes:
Judging whether the current rotation period of the heating section combination meets the maximum operation duration or not;
And if the current rotation period of the heating section combination meets the maximum operation duration, rotating the heating section combination next to the current heating section combination according to the rotation mode when the current rotation period of the heating section combination arrives.
In the embodiment, the maximum operation time is represented as the maximum operation time of the heating section combination, so as to protect the heating section combination, avoid the influence of the long operation time of the heating section combination on the service life of the heating section combination, stop the starting of the heating section combination when the time of the rotation period reaches the maximum operation time, and finally make the working parameters equal or almost equal when the working time difference between the B heating section combination and the A heating section combination is 6 hours and the maximum operation time is 4 hours, determine that the rotation period of the B heating section combination is 4 hours, stop the starting of the B heating section combination and start the A heating section combination for 2 hours after the operation of the B heating section combination reaches the rotation period, restart the B heating section combination for 4 hours when the rotation period of the A heating section combination reaches the rotation period, and finally make the B heating section combination and the A heating section combination equal or almost equal, and after the working time difference between the B heating section combination and the A heating section combination is equal or almost equal, and the starting of the A heating section combination for 2 hours in the follow-up rotation period is 2 hours, so as to avoid the single operation period of the combination, and avoid the service life of the combination from running.
And if the sum of the current heating section combination and the sum of the next heating section combination are equal or almost equal (the difference between the sum of the current heating section combination and the sum of the next heating section combination is smaller than a preset value (such as 0.5 hour)), rotating the current heating section combination and the next heating section combination according to the rotating mode, and if the sum of the current heating section combination and the sum of the next heating section combination are not equal, continuing rotating the current heating section combination.
Therefore, the working parameters of the heating section combinations are similar, the rationality of the operation of the heating section combinations is improved, the precise control of the heating section combinations is realized, and the service life of the heating section combinations is prolonged.
Further, in all heating section combinations meeting the heating condition, if the working time length difference of each heating section combination is larger, the heating section combination with shorter working time length can be continuously operated until the heating section combination with shorter working time length is equal or almost equal to the heating section combination with longer working time length, if the heating section combination meeting the heating condition is provided with an A heating section combination, a B heating section combination and a C heating section combination, wherein the working time length of the A heating section combination is 1 hour, the working time length of the B heating section combination is 5 hours, and the working time length of the C heating section combination is 15 hours, the working time length of the A heating section combination can be operated within the maximum operation time length to be equal or almost equal to the working time length of the B heating section combination, and when the working time length of the A heating section combination is equal to or almost equal to the working time length of the B heating section combination, the working time length of the A heating section combination and the B heating section combination are operated within the maximum operation time length to be equal to or almost equal to the working time length of the C heating section combination.
In some alternative implementations, after the step of alternately activating all the heating segment combinations that meet the heating condition, further comprising:
