[0014] Embodiment 1

[0015] like Figure 1 As shown, the present application provides a temperature monitoring and control method for PVC engineering materials, wherein the method comprises: S100: Acquire the PVC processing flow, identify each processing flow, and sequentially connect the temperature control modules of the processing equipment corresponding to each processing flow; In an embodiment of the present application, the PVC processing process is obtained by retrieving the processing procedures in the production workshop, and each processing process is identified and matched with the corresponding processing equipment in the production workshop according to the PVC processing process, and then the ports of the temperature control modules of the processing equipment corresponding to each processing process are connected in sequence according to the flow order of the processing process. Among them, the PVC processing process is the process steps of processing PVC engineering materials in the production workshop, including mixing, feeding, heating and plasticizing, extrusion molding, cooling, cutting, packaging, etc. Each processing process has corresponding processing equipment, such as the equipment corresponding to heating and plasticizing is an injection molding machine. The temperature control module is a functional module that controls the temperature of the processing equipment corresponding to each processing process during production and processing. For example, the temperature required for heating and plasticizing is 200°C, and 200°C is input into the temperature control module of the injection molding machine to control the temperature during heating and plasticizing at 200°C. By identifying each processing technology flow and connecting the temperature control modules of the corresponding processing equipment in sequence, we can pave the way for subsequent orderly temperature monitoring and control and improve the reliability of temperature monitoring results.

[0016] S200: Outputting a plurality of real-time temperature data by monitoring the temperature of the processing equipment corresponding to each processing process, wherein each real-time temperature data corresponds to a device of a processing process; In one embodiment, a temperature monitoring device is used to monitor the temperature of the processing equipment corresponding to each processing process in real time, and a plurality of real-time temperature data are obtained, wherein each real-time temperature data corresponds to a device of a processing process. The temperature monitoring device is arranged in the temperature control module for real-time temperature monitoring, and can be a thermocouple temperature monitor, a thermistor temperature monitor, a silicon diode temperature monitor, an infrared radiator, etc. The plurality of real-time temperature data reflect the real-time temperature changes of the processing equipment corresponding to each processing process. According to the connection sequence of the plurality of temperature control modules, the temperature monitoring devices in the plurality of temperature control modules are then subjected to temperature data extraction, and a plurality of real-time temperature data with a sequential order are obtained, so as to provide basic data for the subsequent temperature difference calculation of two adjacent processing processes, and pave the way for reliable temperature monitoring and control of engineering materials. The goal of temperature monitoring of each processing process is achieved, and the technical effect of providing a control basis for subsequent temperature control is achieved.

[0017] S300: comparing the real-time temperatures of a processing device corresponding to a previous processing flow and a processing device corresponding to a next processing flow according to the plurality of real-time temperature data to generate a first temperature difference; In one embodiment, by comparing and subtracting the real-time temperature of the processing equipment corresponding to the previous processing process in the PVC processing process with the real-time temperature of the processing equipment corresponding to the next processing process in accordance with the order of the multiple real-time temperature data, the first temperature difference is generated according to the subtraction calculation result. The first temperature difference reflects whether the real-time temperature of the processing equipment corresponding to the previous processing process is higher or lower than the real-time temperature of the processing equipment corresponding to the next processing process. By obtaining the first temperature difference, the temperature difference between two adjacent processing processes is determined, so as to accurately calculate the amplitude of the process temperature change when the PVC material flows between two adjacent processing processes, and provide a basis for subsequent risk analysis.

[0018] S400: Performing a temperature transition risk analysis according to the first temperature difference and the preset temperature difference to obtain a temperature transition risk, wherein the temperature transition risk is a risk of identifying a PVC material passing through two adjacent processing flows; Further, such as Figure 2 As shown, a temperature transition risk analysis is performed according to the first temperature difference and the preset temperature difference to obtain the temperature transition risk. Step S400 of the embodiment of the present application further includes: Obtaining a preset temperature difference, wherein the preset temperature difference is a temperature difference set between a previous processing flow and a next processing flow to prevent the material from solidifying; Temperature transition risk identification is performed based on the first temperature difference and the preset temperature difference, including calculating the mean of the first temperature difference and the preset temperature difference, obtaining the transfer time between the previous processing process and the next processing process, training a transition risk identification layer based on the mean and the transfer time as variables, and obtaining the temperature transition risk based on the transition risk identification layer.

[0019] In one embodiment, the preset temperature difference is the range of temperature difference between the upper and lower processing flow processes set according to the curing conditions of the PVC engineering material. The first temperature difference is compared with the preset temperature difference, and the temperature transition risk analysis is performed according to the comparison result, thereby generating the temperature transition risk. Among them, the temperature transition risk analysis is to analyze the risk degree of affecting the processing quality of the PVC material due to uneven heating of the material during the transfer of the PVC material between the upper and lower processing flow processes due to the large temperature difference between the upper and lower processing flow processes. The temperature transition risk is to identify the risk of material curing when the PVC material passes through two adjacent processing flows.

[0020] Preferably, the preset temperature difference is obtained to provide an analysis basis for temperature transition risk analysis, wherein the preset temperature difference is the temperature difference set between the previous processing technology flow and the next processing technology flow to prevent the material from solidifying. Furthermore, the average of the first temperature difference and the preset temperature difference is calculated as the basic data for risk identification. The time required for the PVC material to transfer from the previous processing technology flow to the next processing technology flow is obtained according to the process regulations for producing and processing PVC materials in the production workshop, as the transfer duration. The mean value and the transfer duration are used as variables and input into the transition risk identification layer for intelligent risk identification, thereby obtaining the temperature transition risk.

[0021] Preferably, by extracting the recorded data of the production workshop producing PVC materials in the historical process, multiple historical means, multiple historical transfer durations and multiple historical temperature transition risks are obtained, a training data set is generated, and the multiple historical temperature transition risks are annotated. The training data set is used to train the framework built based on the convolutional neural network, wherein the training process is to extract features from the training data set by using the convolution layer in the convolutional neural network, and after the feature extraction is completed, the convergence speed of the convolutional neural network is improved by using the normalization layer, so as to achieve the goal of improving the generalization ability of the convolutional neural network, and then, by using the pooling layer to reduce the dimension of the features extracted by the convolution layer, the computational efficiency of the convolutional neural network is improved, and the data to be analyzed is reduced in dimension, so as to analyze the extracted features by using the fully connected layer of the convolutional neural network, and then the analysis results are output through the output layer. During the training process, the training process is supervised by using the annotated multiple historical temperature transition risks until the output reaches convergence, and the transition risk identification layer after convergence is obtained. The technical effect of intelligently identifying the risks of PVC materials passing through two adjacent processing flows and improving the recognition accuracy is achieved.

[0022] S500: When the temperature transition risk is greater than or equal to the preset temperature transition risk, temperature transition control is performed on the processing equipment of the next processing process according to the temperature control module. When the temperature transition control is completed, the PVC material is transferred from the processing equipment corresponding to the previous processing process to the processing equipment corresponding to the next processing process.

[0023] Further, such as Figure 3 As shown, step S500 of the embodiment of the present application also includes: When the temperature transition risk is less than the preset temperature transition risk, obtaining real-time temperature data of the processing equipment corresponding to the next processing process; Based on the real-time temperature data of the processing equipment corresponding to the next processing flow, the temperature stability detection is performed on the processing equipment of the next processing flow. When the temperature stability is not met, the temperature stability instruction is obtained, and the temperature stability compensation control is performed according to the temperature stability instruction.

[0024] Furthermore, step S500 of the embodiment of the present application further includes: By sampling and testing the PVC material, a test data set is obtained, wherein the test data set includes temperature-material state data; Acquire PVC material property information according to the test data set, wherein the PVC material property information includes a property of a temperature-material curing reaction; A preset temperature difference is set according to the PVC material property information, and the preset temperature transition risk is configured by the preset temperature difference.

[0025] In a possible embodiment, after obtaining the temperature transition risk, when the temperature transition risk is greater than or equal to the preset temperature transition risk, it indicates that the risk of PVC material in the transfer process between the upper and lower processing processes is high. Therefore, it is necessary to use the temperature control module to control the temperature transition of the processing equipment of the next processing process. That is to say, according to the size of the temperature transition risk and the temperature difference between the upper and lower processing processes, the processing temperature of the processing equipment of the next processing process is adjusted. When the adjusted result meets the requirements, the processing equipment corresponding to the previous processing process transfers the PVC material to the processing equipment corresponding to the next processing process. The technical effect of determining the risk control object and reducing the risk of material solidification when the PVC material circulates in the processing process is achieved.

[0026] In a possible embodiment, when the temperature transition risk is less than the preset temperature transition risk, it indicates that the risk of the PVC material flowing between the upper and lower processing processes is within the allowable range. The real-time temperature data of the processing equipment corresponding to the next processing process is collected, and then the temperature data of the processing equipment of the next processing process within the preset historical time range is collected based on the real-time temperature data of the processing equipment corresponding to the next processing process, and a historical temperature data set is obtained. Wherein, the preset historical time range is a preset time period before the real-time temperature data, which can be 5 minutes, 10 minutes, etc. The historical temperature data set reflects the temperature change of the processing equipment of the next processing process within the preset historical time range. The difference between the historical temperature data set and the real-time temperature data is calculated to obtain a difference set, and then the variance of the difference set is calculated to determine whether the variance calculation result meets the preset variance. If it meets, the processing equipment of the next processing process meets the temperature stability. If not, the processing equipment of the next processing process does not meet the temperature stability, and the temperature stability instruction is obtained. Wherein, the temperature stability instruction is a command to perform temperature compensation on the processing equipment of the next processing process. The temperature stabilization instruction is input into the temperature control module corresponding to the processing equipment of the next processing process to perform temperature stabilization compensation control. Optionally, the temperature stabilization compensation control is performed by determining the heating temperature range of the temperature heating module of the processing equipment according to the temperature stabilization instruction.

[0027] In one embodiment, the material state of the PVC material at different temperatures is tested by sampling the PVC material, wherein the material state includes the fluidity of the PVC material, and the process of the sampling test is recorded to obtain the test data set, wherein the test data set includes temperature-material state data. The temperature-material state data reflects the flow state of the PVC material at different temperatures. Further, the PVC material property information is obtained according to the temperature-material state data in the test data set. The PVC material property information is used to describe the degree of curing reaction of the PVC material at different temperatures, including the properties of the temperature-material curing reaction. Further, the preset temperature difference is determined according to the temperature difference at which the material undergoes a curing reaction in the PVC material property information. Then, the preset temperature transition risk is configured based on the preset temperature difference.

[0028] Furthermore, step S500 of the embodiment of the present application further includes: Acquire process environment temperature data according to the environment data acquisition equipment; By identifying the environmental temperature impact on the process environmental temperature data, an environmental impact index is output, wherein the environmental impact index is used to identify the degree of impact on the PVC material when the environmental temperature transitions from the previous processing process to the next processing process; The temperature transition risk is adjusted according to the environmental impact index to obtain the adjusted temperature transition risk, and then the adjusted temperature transition risk is compared with the preset temperature transition risk.

[0029] Further, the temperature transition control is performed on the processing equipment of the next processing process according to the temperature control module. Step S500 of the embodiment of the present application further includes: Performing vector processing on a first temperature difference between a processing device corresponding to the previous processing process and a processing device corresponding to the next processing process, and outputting a first temperature difference vector; Wherein, the first temperature difference vector includes the temperature difference direction and the temperature difference magnitude. When the temperature difference direction is positive, it means that the real-time temperature of the processing equipment corresponding to the next processing process is lower than the real-time temperature of the processing equipment corresponding to the previous processing process. When the temperature difference direction is negative, it means that the real-time temperature of the processing equipment corresponding to the next processing process is higher than the real-time temperature of the processing equipment corresponding to the previous processing process. Temperature transition control is performed on processing equipment in the next processing process according to the first temperature difference vector.

[0030] Further, temperature transition control is performed on the processing equipment of the next processing process according to the first temperature difference vector. Step S500 of the embodiment of the present application further includes inputting the first temperature difference vector into a temperature control module for controlling the temperature of the equipment corresponding to the next processing process; If the temperature difference direction of the first temperature difference vector is positive, the real-time temperature of the processing equipment corresponding to the next processing process is increased; if the temperature difference direction of the first temperature difference vector is negative, the real-time temperature of the processing equipment corresponding to the next processing process is reduced.

[0031] In an embodiment of the present application, the production environment data of the production workshop of the PVC material is collected by the environmental data collection device to obtain the process environment temperature data, wherein the process environment temperature data is used to describe the ambient temperature around the processing equipment. The environmental data collection device is a device for collecting data on the workshop environment of the production workshop, including a temperature monitoring sensor, a humidity monitoring sensor, etc. The process environment temperature data is collected by using the temperature monitoring sensor in the environmental data collection device. Furthermore, according to the difference between the process environment temperature data and the preset process environment temperature data, the ratio of the difference to the preset process environment temperature data is used as an environmental impact indicator. The preset process environment temperature data is an environmental temperature value within an allowable range for the workshop environment temperature pre-set by a technician in the field of technology to affect the transfer of PVC materials. Then, the degree of environmental impact on the PVC material when it transitions from the previous processing process flow to the next processing process flow is determined. When the process environment temperature data is too low, the process of transferring the PVC material from the previous processing process to the next processing process will be exposed to the production environment of the workshop. Therefore, it is necessary to adjust the temperature transition risk according to the degree of temperature impact on the PVC material during the transfer process according to the environmental impact index. Among them, the environmental impact index is used to identify the degree of impact on the PVC material when the ambient temperature transitions from the previous processing process to the next processing process.

[0032] Preferably, the temperature transition risk is adjusted to increase the risk value according to the size of the environmental impact index, and then the adjusted temperature transition risk is compared with the preset temperature transition risk, and the risk judgment is made according to the comparison result. By considering the degree to which the PVC material is affected by the workshop environment during the transfer process, the obtained temperature transition risk is adjusted, thereby improving the reliability of risk judgment.

[0033] In one embodiment, according to the magnitude of the real-time temperature of the processing equipment corresponding to the previous processing process flow and the real-time temperature of the processing equipment corresponding to the next processing process flow, the first temperature difference between the processing equipment corresponding to the previous processing process flow and the processing equipment corresponding to the next processing process flow is vectorized. When the real-time temperature of the processing equipment corresponding to the next processing process flow is lower than the real-time temperature of the processing equipment corresponding to the previous processing process flow, the temperature difference direction of the first temperature difference is positive; when the real-time temperature of the processing equipment corresponding to the next processing process flow is higher than the real-time temperature of the processing equipment corresponding to the previous processing process flow, the temperature difference direction of the first temperature difference is negative, and then, a first temperature difference vector is obtained. The first temperature difference vector reflects the magnitude and direction of the temperature difference between the processing equipment corresponding to the previous processing process flow and the processing equipment corresponding to the next processing process flow, including the temperature difference direction and the temperature difference magnitude. Then, the temperature transition control is performed on the processing equipment of the next processing process flow according to the first temperature difference vector. Optionally, when the temperature difference direction of the first temperature difference vector is positive, the real-time temperature of the processing equipment corresponding to the next processing process flow is increased; when the temperature difference direction of the first temperature difference vector is negative, the real-time temperature of the processing equipment corresponding to the next processing process flow is reduced. The technical effect of reliable and accurate temperature monitoring and control of PVC engineering materials has been achieved.

[0034] In summary, the embodiments of the present application have at least the following technical effects: This application obtains the processing technology of PVC engineering materials, connects the temperature control module according to the order of process flow, and then compares the real-time temperature of the processing equipment corresponding to the previous processing technology and the processing equipment corresponding to the next processing technology, determines the first temperature difference, and performs temperature transition risk analysis in combination with the preset temperature difference. When the temperature transition risk is greater than or equal to the preset temperature transition risk, the temperature transition control is performed on the processing equipment of the next processing technology according to the temperature control module, and then when the temperature transition control is completed, the processing equipment corresponding to the previous processing technology transfers the PVC material to the processing equipment corresponding to the next processing technology. The technical effect of improving the reliability of temperature monitoring and control of PVC engineering materials and improving the quality of material processing is achieved.
