Before explaining the embodiments of the present application in detail, an application scenario of the embodiments of the present application will be described.
The temperature control method provided by the embodiment of the application is applied to a scene of homogenizing glass and is used for controlling the temperature of the glass to meet the actual production requirement, the heating time and the waiting time of a heating stage and a heat preservation stage in a first period in the homogenizing treatment process are set, and the heating time and the waiting time from a second period to a last period in a plurality of periods are adjusted and obtained, so that the temperature difference value of the glass between two adjacent periods in the plurality of periods is in a reasonable range, the temperature difference value of the glass in a second preset time period is ensured to be less than or equal to a preset temperature difference value, and the temperature of the glass in the homogenizing treatment process meets the actual production requirement.
The temperature control method provided in the embodiments of the present application is explained in detail below.
Fig. 1 is a flowchart of a temperature control method according to an embodiment of the present disclosure. Referring to fig. 1, the method includes the following steps.
Step 101: before homogenizing the glass, the terminal sets the heating time and waiting time of the first period in a plurality of periods.
The homogenizing treatment is to put the glass into a homogenizing device, and comprises a temperature rising stage, a temperature preservation stage and a temperature reduction stage.
Each of the plurality of periods is a period of a temperature rise period and a heat preservation period in the homogenization treatment process, and a duration of each of the plurality of periods is a first preset duration, and the first preset duration may be preset, for example, the first preset duration may be set to 10s (seconds).
The heating time refers to the time for heating the glass; the waiting time means a time for stopping heating of the glass.
In this case, the terminal may intermittently heat the glass according to the heating time and waiting time of the first cycle, rather than continuously heat the glass all the time, so that the temperature rising rate of the glass may be reduced.
Specifically, the operation of step 101 may be: the terminal obtains the loading rate of the glass in the homogenizing equipment; the heating time and waiting time of the first cycle are set according to the loading rate.
The loading rate is used to indicate the amount of glass in the homogenizing apparatus, the loading rate being the ratio of the volume of glass in the homogenizing apparatus to the total volume of the homogenizing apparatus.
In this case, the terminal acquires the loading rate of the glass in the homogenizing apparatus to know the amount of the glass in the homogenizing apparatus, so that the heating time and the waiting time of the first cycle can be accurately set according to the amount of the glass in the homogenizing apparatus.
The operation that the terminal sets the heating time and the waiting time of the first period according to the loading rate may be: according to the loading rate, acquiring corresponding heating time from the corresponding relation between the stored loading rate and the heating time as the heating time of the first period; and subtracting the heating time of the first period from the first preset time length to obtain the waiting time of the first period.
The correspondence relationship between the loading rate and the heating time stored in the terminal includes a plurality of loading rates and a plurality of heating times, and the plurality of loading rates and the plurality of heating times are in one-to-one correspondence. For any one of the loading rates in the corresponding relationship, a heating time corresponding to the loading rate in the corresponding relationship is a time preset by a technician to be able to reasonably heat the amount of glass indicated by the loading rate.
For example: if the loading rate obtained by the terminal is 0.6, the heating time corresponding to the loading rate of 0.6 can be obtained as 5s from the correspondence between the loading rate and the heating time shown in table 1 below, and the heating time of the first cycle can be set as 5s.
TABLE 1
| Loading rate | Time of heating |
| 0.2 | 3s |
| 0.4 | 4s |
| 0.6 | 5s |
| 0.8 | 6s |
| …… | …… |
In the present embodiment, the correspondence between the loading rate and the heating time is described only by taking table 1 as an example, and table 1 does not limit the present embodiment.
In this case, the terminal obtains the heating time corresponding to the loading rate from the stored correspondence between the loading rate and the heating time, so as to obtain the heating time of the first period, and then subtracts the heating time of the first period from the time of the first period (i.e., the first preset time), so as to obtain the waiting time of the first period, so that the terminal can more quickly and accurately set the heating time and the waiting time of the first period.
For example: the first preset time is 10s, the loading rate obtained by the terminal is 0.6, the heating time corresponding to the loading rate of 0.6 is obtained from the corresponding relation between the stored loading rate and the heating time and is 5s, namely the heating time of the first period is 5s, and then the heating time of the first period is subtracted from the first preset time 10s to obtain the waiting time of the first period which is 5s.
Step 102: in the process of homogenizing the glass, the terminal takes the current period in the plurality of periods as the current period, and executes the following steps 1021-1022 to control the temperature difference value of the glass within the second preset time period to be less than or equal to the preset temperature difference value.
The second preset time period may be preset and may be set according to actual requirements of the glass manufacturing process, for example, the second preset time period may be set to 1 minute.
The preset temperature difference value may be set in advance, and the preset temperature difference value may be set according to actual requirements of the glass manufacturing process, for example, the preset temperature difference value may be set to 3 ℃.
In this case, the terminal may control the temperature difference of the glass in the second preset time period to be less than or equal to the preset temperature difference by performing steps 1021 to 1022 for each of the plurality of periods.
Step 1021: if the current period is the first period, the terminal heats the glass according to the heating time and the waiting time of the current period; acquiring the temperature of the glass at the end of the current period; and determining the heating time and the waiting time of the second period in the plurality of periods according to the temperature difference between the initial temperature of the glass before the homogenization treatment and the temperature at the end of the current period.
If the temperature difference is within the first period, the terminal takes the first period as the current period, the terminal firstly heats the glass according to the heating time of the current period, then the terminal stops heating according to the waiting time of the current period, the temperature of the glass is obtained when the current period is finished, the temperature difference between the initial temperature of the glass before homogenization treatment and the temperature when the current period is finished can be known, and then the heating time and the waiting time of the second period are determined according to the temperature difference, so that the temperature difference between the temperature when the second period is finished and the temperature when the first period is finished is within a reasonable range.
Optionally, a plurality of thermocouple elements are included in the homogenizing apparatus, the plurality of thermocouple elements can detect the temperature of the glass in the homogenizing apparatus, and the operation of acquiring the temperature of the glass at the end of the current period by the terminal can be: at the end of the current cycle, the temperature of the glass in the homogenizing apparatus is obtained by the plurality of thermocouple elements.
In this case, the plurality of thermocouple elements can accurately detect the glass temperature in the homogenizing apparatus, so that the terminal obtains the glass temperature in the homogenizing apparatus through the plurality of thermocouple elements, and the obtained glass temperature can be more accurate.
Specifically, the terminal acquires the temperature detected by each thermocouple element in the plurality of thermocouple elements; the average value of the temperatures detected by the plurality of thermocouple elements was taken as the temperature of the glass in the homogenizing apparatus.
For example: the homogenizing device comprises 3 thermocouple elements, and the temperatures detected by the 3 thermocouple elements obtained by the terminal are respectively 50 ℃, 50.2 ℃ and 50.4 ℃. The terminal can determine the temperature of the glass in the homogenizing apparatus as (50 +50.2+ 50.4) ÷ 3=50.2 ℃.
The operation of the terminal determining the heating time and the waiting time of the second period in the plurality of periods according to the temperature difference between the initial temperature of the glass before the homogenization treatment and the temperature at the end of the current period may be: if the temperature difference between the initial temperature of the glass before the homogenization treatment and the temperature at the end of the current period is smaller than the temperature difference threshold, taking the heating time and the waiting time of the current period as the heating time and the waiting time of a second period; and if the temperature difference between the initial temperature of the glass before the homogenization treatment and the temperature at the end of the current period is greater than or equal to the temperature difference threshold, reducing the heating time of the current period by a preset value to obtain the heating time of a second period, and increasing the waiting time of the current period by the preset value to obtain the waiting time of the second period.
The temperature difference threshold may be preset, and the temperature difference threshold may be set according to a preset temperature difference.
Optionally, the terminal divides the second preset duration by the first preset duration to obtain a duration ratio; and dividing the preset temperature difference value by the time length ratio to obtain a temperature difference value threshold.
Therefore, if the temperature difference value of every two adjacent periods of the glass in the second preset time is smaller than the temperature difference value threshold, the temperature difference value of the glass in the second preset time can be ensured to be smaller than or equal to the preset temperature difference value.
For example, the second preset time period is 1 minute, the first preset time period is 10s, and the preset temperature difference is 3 ℃, then the terminal divides the second preset time period by the first preset time period for 10s to obtain 60 ÷ 10=6, and the time-length ratio is 6. And then dividing the preset temperature difference of 3 ℃ by the time length ratio of 6 to obtain 3 ÷ 6=0.5, namely, the temperature difference threshold is 0.5 ℃.
The preset value can be preset and can be set to be smaller, so that the heating time and the waiting time of the current period can be finely adjusted, the problems that the heating time is adjusted to be too small and the waiting time is adjusted to be too large are solved, the temperature difference value between the temperature of the glass at the end of the second period and the temperature of the glass at the end of the first period is required to be within a reasonable range, and the preset value can be set to be 1s.
In this case, if the temperature difference between the initial temperature of the glass before the homogenization treatment and the temperature at the end of the current cycle is smaller than the temperature difference threshold, which indicates that the temperature difference between the glass temperature and the initial temperature of the glass at the end of the first cycle is normal, the heating time and the waiting time of the current cycle may be regarded as the heating time and the waiting time of the second cycle, that is, the treatment of the second cycle may be continued in accordance with the heating time and the waiting time of the first cycle.
If the temperature difference between the initial temperature of the glass before the homogenization treatment and the temperature at the end of the current period is greater than or equal to the temperature difference threshold, it indicates that the temperature difference between the temperature of the glass at the end of the first period and the initial temperature of the glass is large, and thus the temperature difference of the glass in the second preset time period may exceed the preset temperature difference, which may cause the temperature of the glass in the homogenization treatment process to be not in accordance with the actual production requirement, the terminal adjusts the heating time and the waiting time of the first period to obtain the heating time and the waiting time of the second period, that is, the heating time of the second period is reduced and the waiting time of the second period is increased compared with the first period, so that the temperature rise rate of the glass in the second period is reduced, and the temperature difference between the temperature of the glass at the end of the second period and the temperature of the glass at the end of the first period is less than or equal to the temperature difference threshold.
Step 1022: if the current period is one period from the second period to the last period in the plurality of periods, the terminal heats the glass according to the heating time and the waiting time of the current period; acquiring the temperature of the glass at the end of the current period; the heating time and waiting time for the next cycle are determined based on the temperature difference between the temperature of the glass at the end of the previous cycle and the temperature at the end of the current cycle.
If the current period is one period from the second period to the last period in the plurality of periods, the terminal heats the glass according to the heating time of the current period, then the terminal stops heating according to the waiting time of the current period, and the temperature of the glass is obtained at the end of the current period, so that the temperature difference between the temperature of the glass at the end of the last period and the temperature at the end of the current period can be known, and then the heating time and the waiting time of the next period are determined according to the temperature difference, so that the temperature difference between the temperature at the end of the next period and the temperature at the end of the current period is in a reasonable range.
In this way, the operation is performed for each of the second period to the last period of the plurality of periods, so that the temperature difference value of the glass in the second preset time period is smaller than or equal to the preset temperature difference value.
The operation of acquiring the temperature of the glass by the terminal at the end of the current period is the same as the operation of acquiring the temperature of the glass by the terminal at the end of the current period in step 1021, and details of the operation are not repeated herein.
Wherein, the operation of the terminal determining the heating time and the waiting time of the next period according to the temperature difference between the temperature of the glass at the end of the last period and the temperature at the end of the current period may be: if the temperature difference value between the temperature of the glass at the end of the last period and the temperature at the end of the current period is smaller than the temperature difference value threshold value, taking the heating time and the waiting time of the current period as the heating time and the waiting time of the next period; and if the temperature difference value between the temperature of the glass at the end of the last period and the temperature of the glass at the end of the current period is greater than or equal to the temperature difference value threshold, reducing the heating time of the current period by a preset value to obtain the heating time of the next period, and increasing the waiting time of the current period by the preset value to obtain the waiting time of the next period.
In this case, if the temperature difference between the temperature of the glass at the end of the previous cycle and the temperature at the end of the current cycle is smaller than the temperature difference threshold, which indicates that the temperature difference between the temperature of the glass at the end of the previous cycle and the temperature at the end of the current cycle is normal, the heating time and the waiting time of the current cycle are taken as the heating time and the waiting time of the next cycle, that is, the processing of the next cycle is continued according to the heating time and the waiting time of the current cycle.
If the temperature difference value between the temperature of the glass at the end of the last period and the temperature at the end of the current period is greater than or equal to the temperature difference value threshold, which indicates that the temperature difference value between the temperature of the glass at the end of the last period and the temperature at the end of the current period is large, and thus the temperature difference value of the glass in the second preset time period is likely to exceed the preset temperature difference value, namely the temperature of the glass does not meet the actual production requirement in the homogenization treatment process, the heating time and the waiting time of the current period are adjusted by the terminal to obtain the heating time and the waiting time of the next period, namely the heating time of the next period is reduced compared with the current period, and the waiting time of the next period is increased to reduce the heating rate of the glass in the next period, so that the temperature difference value between the temperature of the glass at the end of the next period and the temperature of the glass at the end of the current period is less than or equal to the temperature difference value threshold.
For example: the temperature difference threshold is 0.5 ℃, the preset value is 1s, the heating time of the current period is 4s, and the waiting time is 6s. If the terminal acquires that the temperature of the glass at the end of the last period is 53 ℃ and the temperature of the glass at the end of the current period is 53.6 ℃, the temperature difference between the temperature of the glass at the end of the last period and the temperature of the glass at the end of the current period is 0.6 ℃ and is greater than the temperature difference threshold value by 0.5 ℃, the terminal reduces the heating time 4s of the current period by 1s to obtain the heating time of the next period as 3s, and increases the waiting time 6s of the current period by 1s to obtain the waiting time of the next period as 7s.
