Description

TECHNICAL FIELD

[0001] The present application relates to the field of fiber temperature control, in particular to a mixed fiber temperature control system with cross heating function. BACKGROUND

[0002] In many industrial production and scientific research application scenarios, mixed fiber materials are increasingly widely used. Temperature control plays a crucial role in the performance and quality of mixed fibers. Different mixed fibers have their own unique thermophysical properties, and their performance indicators such as strength, elasticity, and electrical conductivity will change significantly with temperature. During the processing and manufacturing of mixed fibers, accurate temperature control can ensure the uniformity and stability of the internal structure of the fiber material, and avoid defects and performance degradation caused by uneven temperature; during the use of mixed fiber products, a suitable temperature environment helps to maintain the durability and reliability of their performance.

[0003] Traditional heating modes mostly use single-area heating mode. This mode is relatively simple and extensive in design, and usually controls the entire heating area uniformly, which cannot accurately adjust the temperature state of different sub-areas of mixed fibers. During the heating process, due to differences in fiber characteristics, density, heat dissipation conditions, and other factors, the temperature changes of different sub-areas are different, but the traditional mode can only operate according to uniform heating parameters, and cannot perform differential heating according to the actual situation of each sub-area, resulting in overheating or overcooling in some areas, affecting the heating effect and quality stability of mixed fibers. Moreover, due to the single heating mode of the traditional temperature control method, it cannot be adjusted in real time according to the temperature changes of different areas, resulting in temperature gradient during the heating process, i.e. there is a significant temperature difference between different areas. This temperature non-uniformity will affect the physical and chemical properties of mixed fibers and reduce the quality consistency of products. SUMMARY

[0027] The temperature sensing processing module includes a temperature collection unit and a temperature data processing unit. The temperature collection unit is used to obtain different area temperature data based on the deployment parameters and bind the area identifier, and the process includes: Read the communication identifiers J[a] and C[b] in the device deployment parameters, and record the preset collection period T 采 , T 采 = [t 始 , t 终 ], where t 始 is the start time of the collection period, t 终 is the end time of the collection period, and the temperature collection unit establishes a communication connection with the temperature collection device within T 采 ; Start the temperature collection device at t 始 , collect the temperature inside the mixed fiber through the contact temperature sensor, record it as T 内 , and collect the temperature on the surface of the mixed fiber through the infrared temperature detector, record it as T 表 , the temperature monitoring data includes T 内 and T 表 , and the T 内 and T 表 of each collection time are time stamped, recorded as T 内 (t) and T 表 (t), where t is any time between t 始 and t 终 ; At t 终 , bind the collection sub-area number b with the corresponding temperature monitoring data to generate temperature monitoring data with area identifier, and the area identifier is the collection sub-area position information corresponding to the number b.

[0028] The temperature data processing unit is used to fuse to generate comprehensive temperature data associated with the heating sub-area, and distribute to several transmission channels for transmission, associated with the channel number and the heating sub-area number, and integrated into a comprehensive temperature data set, and the process includes: Traverse the region to identify the corresponding temperature monitoring data, convert T 内 (t) and T 表 (t) into a unified data format, denoted as standardized temperature data; Set a preset coincidence threshold, which is used to determine whether the change trend of the internal temperature and the surface temperature of the mixed fiber is consistent; Feature extraction is performed on the standardized temperature data: taking the timestamp as the horizontal coordinate, and taking T 内 (t) and T 表 (t) converted into a unified data format as the vertical coordinate to generate a temperature change curve, denoted as curve L 内 and curve L 表 ; Calculate the coincidence degree R 内 of curve L 表 and curve L 重 : R 重 = length of coincident period / total collection period length, for example, if the trend is consistent for 8 minutes in a 10-minute collection period, then R 重 = 0.8, when R 重 ≥ preset coincidence threshold, take the average of T 内 (t) and T 表 (t) at the corresponding time as the fusion temperature value T 融 (t); when R 重 < preset coincidence threshold, keep T 内 (t) and T 表 (t) as independent temperature values; Summarize all fusion temperature values and independent temperature values, and generate mixed fiber comprehensive temperature data T 融综 in combination with the region identifier, the mixed fiber comprehensive temperature data T 融综 is associated with the collection sub-region number b and the corresponding heating sub-region number a.

[0029] Set several transmission channels, each transmission channel corresponds to a heating sub-region number a, denoted as S[a], for example, heating sub-region numbers a=1 and a=2, the corresponding transmission channels are S[1] and S[2], and the part of mixed fiber comprehensive temperature data T 融综 associated with number a is allocated to the corresponding transmission channel; Get the real-time transmission bandwidth of each transmission channel, denoted as K[a], and adjust the transmission rate of the mixed fiber comprehensive temperature data T 融综 of the channel according to K[a], so that the transmission rate ≤ K[a]; Set a data check code for each transmission channel, which is used to verify the integrity of the transmission data, and when the data is found to be missing, trigger the supplementary transmission of the adjacent channel; The transmission data of each channel is marked as a "partition temperature data packet", and the "partition temperature data packet" is associated with the transmission channel number S[a] and the corresponding heating sub-area number a. The comprehensive temperature data T is integrated into a mixed fiber comprehensive temperature data set according to the "partition temperature data packet", and is denoted as T 融集 .

[0030] It should be noted that the fusion temperature value and the independent temperature value are set to balance the reliability of the temperature data and the pertinence of the temperature control strategy: when the coincidence degree of the internal and surface temperature change trends of the mixed fiber meets the standard, the mean value is taken as the fusion temperature value, which can offset the error of a single sensor and obtain a more accurate comprehensive temperature close to the real state, thereby providing a reliable basis for the cooperative heating strategy; when the coincidence degree is insufficient, the independent temperature value is retained to avoid data distortion and reflect the abnormal difference between the internal and surface temperatures, thereby providing original data support for targeted regulation, such as individual adjustment of the internal or surface and subsequent investigation of the deviation reason.

If T 现 [a] is reached, the power of the auxiliary heating wire is reduced in time to avoid entering the "temperature reduction state" and forming a dynamic balance. 高 If the adjacent sub-area is in the "heating state", all corresponding heating devices are started synchronously, including the cross heating plate and auxiliary heating wire in the heating sub-area and the adjacent sub-area. If the adjacent sub-area is in the "temperature reduction state", no heating device of the adjacent sub-area is started to avoid inputting additional heat to the adjacent area, and the power of the heating device of the sub-area is controlled at the basic heating power, which is calculated based on the difference between T 低 [a] and T 现 [a].

[0033] The instruction generation unit generates a cross heating strategy based on the mixed fiber temperature data set T 融集 and the preset heating threshold T 低 [a], T 高 [a].For the heating sub-area in the "heating state", the cross heating strategy is generated according to the state of the adjacent heating sub-area, fully considering the mutual influence between the heating areas, and by adjusting the start of the heating device and the power of different areas, the problems of inputting additional heat to the adjacent area or heat overflow are avoided, the heating efficiency and the accuracy of temperature control are effectively improved, and the traditional single area heating control mode has obvious innovation and advantage.

[0034] The temperature control feedback unit obtains the execution result of the cross heating control instruction, calculates the heating temperature control accuracy, and dynamically adjusts the preset heating threshold according to the temperature control accuracy, which includes: The temperature collection unit collects the mixed fiber temperature data after the execution of the cross heating control instruction, denoted as T后 [a], the collection sub-region corresponding to the heating sub-region number a; Calculate the temperature control precision P 精 [a], as follows: P 精 [a]=|T 后 [a]-target temperature| / (T 高 [a]-T 低 [a]); Wherein, the target temperature is (T 高 [a]+T 低 [a]) / 2; Set the temperature control precision threshold P 合 : When P 精 [a]≤P 合 , it is determined that the heating sub-region temperature control is qualified; When P 精 [a]>P 合 , it is determined that the heating sub-region temperature control is unqualified; For unqualified heating sub-regions, adjust their preset heating thresholds T 低新 [a] and T 高新 [a], as follows: T 低新 [a]=T 低 [a]-ΔT; T 高新 [a]=T 高 [a]+ΔT; Wherein, ΔT is an adjustment coefficient, determined based on the difference between P 精 [a] and P 合 .

[0035] The system management module is used to read the cross heating control instruction, the heating threshold T 低新 [a] and T 高新 [a] adjusted by the temperature control feedback unit, and the device operating parameters (including the rated power of the heating device and the running time limit) stored by the control center, and is used to execute the corresponding hybrid fiber temperature control management measures according to the above data. The process of executing the temperature control management measures includes: According to the cross heating control instruction, start the corresponding heating device. For the sub-region in the "heating required state", run according to the power P and heating time in the instruction, and read the device operating parameters in real time to ensure that the actual power ≤ rated power; When the device operating parameters exceed the limit, for example, the running time exceeds the limit, generate a device pause instruction, and at the same time, trigger the adjacent heating sub-region to perform supplementary heating based on the cross heating strategy; Periodically, the device operation data and temperature control feedback results are summarized as a "temperature control management report", the report is associated with the heating sub-area number a and the corresponding mixed fiber type, and is fed back to the device selection unit of the heating device deployment module, which is used for subsequent device selection optimization.
