The present invention collects the temperature in real time during the special resin synthesis reaction to construct a real-time temperature curve, and compares the real-time temperature curve with the standard temperature curve in sections, thereby splitting the temperature control during the special resin synthesis reaction, supplementing the next time period unit with the temperature deviation degree of the previous time period unit, and refining each temperature control process.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0010] And according to the effect of coordinated control, the temperature adjustment state of the special resin synthesis reaction is identified.

[0011] As a further solution of the present invention: the construction process of the real-time temperature curve is:

[0012] During the special resin synthesis reaction, the reaction temperature is collected in real time, and a plane coordinate system is constructed with the reaction time as the X-axis and the reaction temperature as the Y-axis;

[0013] A real-time temperature curve is constructed with real-time reaction temperature in a plane coordinate system.

[0014] As a further solution of the present invention: the standard temperature curve is a standard curve of temperature variation over time during the special resin synthesis reaction process;

[0015] The standard temperature curve is the curve obtained by fitting the optimal temperature change over time during the special resin synthesis reaction.

[0016] As a further solution of the present invention: the entire process time of the special resin synthesis reaction is divided into a plurality of time period units;

[0017] The standard temperature curve is intercepted according to the time corresponding to the real-time unit temperature curve to obtain the standard unit temperature curve;

[0024] If the temperature trend change value of the time period unit corresponding to the current time is greater than zero, it means that the temperature of the special resin synthesis reaction is too high in the current time period unit, and it is necessary to reduce the temperature of the special resin synthesis reaction in the next time period unit to generate the next unit temperature adjustment signal;

[0025] If the temperature trend change value of the time period unit corresponding to the current time is less than zero, it means that the temperature of the special resin synthesis reaction is too low in the current time period unit, and it is necessary to increase the temperature of the special resin synthesis reaction in the next time period unit to generate the next unit temperature adjustment signal;

[0027] As a further solution of the present invention: in the temperature control process of the special resin synthesis reaction process, temperature control data is obtained;

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] Example 1, please refer to Figure 1 As shown, the present invention is a method for intelligently controlling the temperature of a special resin synthesis reaction, comprising the following steps:

[0045] During the special resin synthesis reaction process, the reaction temperature is collected in real time, and a real-time temperature curve is constructed based on the collected temperature;

[0046] The real-time temperature curve is compared with the standard temperature curve in sections, and the temperature in the special resin synthesis reaction process is coordinated and controlled according to the comparison results;

[0047] And according to the effect of coordinated control, the temperature adjustment state of the special resin synthesis reaction is identified.

[0048] During the special resin synthesis reaction, the reaction temperature is collected in real time, and a plane coordinate system is constructed with the reaction time as the X-axis and the reaction temperature as the Y-axis;

[0049] Constructing a real-time temperature curve with real-time reaction temperature in a plane coordinate system;

[0050] At the same time, a standard temperature curve is constructed in the plane coordinate system;

[0051] Among them, the standard temperature curve is a standard curve of the temperature change over time during the special resin synthesis reaction process. The quality of the special resin synthesis reaction obtained by following the standard temperature curve is the highest.

[0052] It should be noted that the standard temperature curve is the curve obtained by fitting the optimal temperature change over time during the special resin synthesis reaction.

[0053] During the entire process of the special resin synthesis reaction, the entire process time is divided into several time period units;

[0054] According to the reaction time sequence, the reaction temperature of each time period unit is processed in turn, that is, the processing process is the first time period unit, the second time period unit, ..., the nth time period unit;

[0055] This embodiment processes the first time period unit to obtain a real-time unit temperature curve corresponding to the first time period unit;

[0056] The standard temperature curve is intercepted according to the time corresponding to the real-time unit temperature curve to obtain the standard unit temperature curve;

[0057] Compare the real-time unit temperature curve with the standard unit temperature curve;

[0058] The real-time unit temperature curve and the standard unit temperature curve are divided into a number of time nodes according to the same time length;

[0059] Get the temperature value corresponding to the real-time unit temperature curve at each time node;

[0060] Get the temperature value corresponding to the standard unit temperature curve at each time node;

[0061] Perform difference processing on the temperature value corresponding to the real-time unit temperature curve at each time node and the temperature value corresponding to the standard unit temperature curve to obtain the temperature deviation value of the time node;

[0062] Sum the temperature deviation values ​​of all time nodes to obtain the temperature trend change value of the time period unit corresponding to the current time;

[0063] If the temperature trend change value of the time period unit corresponding to the current time is greater than zero, it means that the temperature of the special resin synthesis reaction is too high in the current time period unit, and it is necessary to reduce the temperature of the special resin synthesis reaction in the next time period unit to generate the next unit temperature adjustment signal;

[0064] If the temperature trend change value of the time period unit corresponding to the current time is less than zero, it means that the temperature of the special resin synthesis reaction is too low in the current time period unit, and it is necessary to increase the temperature of the special resin synthesis reaction in the next time period unit to generate the next unit temperature adjustment signal;

[0065] If the temperature trend change value of the time period unit corresponding to the current time is equal to zero, it means that the temperature of the special resin synthesis reaction is appropriate in the current time period unit, and the special resin synthesis reaction is carried out at the predetermined temperature in the next time period unit to generate the next unit temperature non-adjustment signal.

[0066] Based on the next unit temperature adjustment signal, the temperature of the special resin synthesis reaction in the unit in the next time period after the current time is adjusted;

[0067] The process is repeated in sequence until the temperatures of all time period units in the real-time unit temperature curve are adjusted.

[0068] In the temperature control process of the special resin synthesis reaction process, the absolute value of the temperature trend change value of each time period unit is taken to obtain the temperature change deviation value of the time period unit;

[0069] The temperature deviation values ​​of all time period units are summed and averaged to obtain the total temperature deviation value during the special resin synthesis process;

[0070] The total temperature deviation value is processed by ratio processing with the temperature deviation threshold value to obtain the total temperature deviation ratio in the special resin synthesis process;

[0071] Then, the temperature deviation values ​​of all time period units are processed according to the variance calculation formula to obtain the temperature variance value in the special resin synthesis process;

[0072] The maximum and minimum values ​​of the temperature trend change value of the time period unit are calculated by difference, and the temperature trend limit value of the time period unit is obtained;

[0073] The temperature trend limit value of the time period unit is processed by ratio with the temperature mean value of the special resin synthesis reaction process to obtain the temperature limit deviation ratio in the special resin synthesis process;

[0074] The total temperature deviation ratio during the synthesis of the special resin is recorded as W1;

[0075] The temperature variance value during the special resin synthesis process is recorded as W2;

[0076] The temperature limit deviation ratio during the special resin synthesis process is recorded as W3;

[0077] Calculated by formula The special resin synthesis reaction temperature adjustment state value Wi is obtained, wherein d1, d2, and d3 are all preset proportional coefficients, and d1, d2, and d3 are all greater than zero.

[0078] Compare the special resin synthesis reaction temperature adjustment state value Wi with the special resin synthesis reaction temperature adjustment state threshold value Wy;

[0079] If the special resin synthesis reaction temperature adjustment state value Wi is greater than or equal to the special resin synthesis reaction temperature adjustment state value Wy, it means that the special resin synthesis reaction temperature adjustment state is good;

[0080] If the special resin synthesis reaction temperature adjustment state value Wi is less than the special resin synthesis reaction temperature adjustment state value Wy, it means that the special resin synthesis reaction temperature adjustment state is poor.

[0081] Example 2, please refer to Figure 2 As shown, the present invention is a special resin synthesis reaction temperature intelligent control system, comprising:

[0082] The temperature building module is used to collect the reaction temperature in real time during the special resin synthesis reaction process and build a real-time temperature curve based on the collected temperature;

[0083] A collaborative control module is used to compare the real-time temperature curve with the standard temperature curve in sections, and to collaboratively control the temperature during the special resin synthesis reaction according to the comparison results;

[0084] The control and identification module is used to identify the temperature adjustment state of the special resin synthesis reaction according to the effect of coordinated control.
