[0002] In the era of automation, automated control reaction equipment is increasingly used in many large chemical plants or pharmaceutical plants. The traditional industrial production process includes: manually inputting chemical raw materials, manually setting relevant parameters and waiting for the reaction to be completed, taking samples for inspection during the reaction, and controlling the chemical reaction process based on the inspection results. Since the sampling and inspection operation during the reaction process is an offline operation and it takes a certain amount of time to issue the inspection results, the control process based on the inspection results has a certain lag and cannot be adjusted online in real time, which affects the control accuracy of the chemical reaction, and ultimately leads to problems such as impure products and increased by-products. So far, how to improve the control accuracy of chemical reactions is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0037] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present disclosure.

[0038] <Method Example>

[0039] Figure 1 FIG. 1 is a flow chart showing a method for automatically controlling a chemical reaction according to an embodiment of the present disclosure. Figure 1 As shown, the method includes steps S1100-S1300.

[0040] S1100, obtaining a material characteristic value of a material currently added to a chemical reaction, and determining the currently ongoing chemical reaction and an endpoint threshold of the chemical reaction according to the material characteristic value.

[0041] In a possible implementation, when obtaining the material characteristic value of the material currently added to the chemical reaction, the following steps may be included:

[0042] First, the physical characteristics of the material are obtained, wherein the physical characteristics of the material may include at least one of electrical conductivity, density and thermal conductivity. Specifically, the material is fed into the reactor through a feed pipe. In order to obtain the physical characteristics of the material, various sensors for detecting physical characteristics are arranged on the feed pipe, so as to obtain the physical characteristics of the material through the sensors arranged on the feed pipe. For example, when the physical characteristics include electrical conductivity, density and thermal conductivity, a conductivity sensor, a density sensor and a thermal conductivity sensor will be arranged on the feed pipe, so that after the material passes through the various sensors on the feed pipe, the physical characteristics such as electrical conductivity, density and thermal conductivity of the material currently passing through the feed pipe can be obtained through the various sensors.

[0043] Second, based on the physical characteristics, the material characteristic value of the material is calculated. Specifically, the acquired physical characteristics can be logically operated to obtain the physical characteristic value of the material. For example, when the physical characteristics of the material include electrical conductivity X, density Y, and thermal conductivity Z, the material characteristic value A of the material can be calculated by the logical operation shown below.

[0044]

[0045] After obtaining the material characteristic value, the chemical reaction currently being performed and the endpoint threshold of the chemical reaction currently being performed can be determined based on the material characteristic value. In a possible implementation, when determining the chemical reaction currently being performed and the endpoint threshold of the chemical reaction based on the material characteristic value, it is implemented based on a pre-constructed first mapping relationship table, wherein the first mapping relationship table records the mapping relationship between the material characteristic value, the chemical reaction, and the chemical reaction threshold. Specifically, Figure 2 As shown, a material information module is provided in the system for executing the method disclosed herein, and the material information module is further divided into an information input module, an information identification module and an information storage module. Before executing the method disclosed herein, it is necessary to first input each chemical reaction through the information input module, as well as the material characteristic value of the material required for each chemical reaction and the endpoint threshold of the chemical reaction, and store the input information in the form of a first mapping relationship table in the information storage module, so that when the information identification module identifies and obtains the material characteristic value of the material currently added to the chemical reaction, the chemical reaction corresponding to the currently obtained material characteristic value and the endpoint threshold of the chemical reaction can be found by querying the first mapping relationship table stored in the information storage module, and the chemical reaction corresponding to the currently obtained material characteristic value is used as the chemical reaction currently being carried out, and the endpoint threshold corresponding to the currently obtained material characteristic value is used as the endpoint threshold of the chemical reaction currently being carried out. For the convenience of description, the chemical reaction currently being carried out is uniformly referred to as a chemical reaction in the following text.

[0046] S1200, based on the endpoint threshold, determine the monitoring parameters of the chemical reaction, and call the sensor corresponding to the monitoring parameter to monitor the monitoring parameter. Among them, the endpoint threshold is actually the value reached by the corresponding monitoring parameter when the chemical reaction ends, that is, the endpoint threshold and the corresponding monitoring parameter are one-to-one corresponding. Therefore, before executing this step, it is necessary to first construct a mapping relationship between each endpoint threshold and the monitoring parameter to be monitored in the chemical reaction, and store the mapping relationship in the form of a second mapping relationship table. In this way, when the endpoint threshold of the chemical reaction is obtained, the monitoring parameters to be monitored in the chemical reaction can be determined by querying the second mapping relationship table.

[0047] For example, if the monitoring parameter corresponding to the temperature threshold is temperature, and the detection parameter corresponding to the pressure threshold is pressure, the second mapping relationship table will record the monitoring parameter temperature corresponding to the temperature threshold and the monitoring parameter pressure corresponding to the pressure threshold. In this way, when the temperature threshold is obtained, it can be determined that the monitoring parameter that needs to be monitored for the chemical reaction is temperature.

[0048] After determining the monitoring parameters of the chemical reaction, the sensors corresponding to the monitoring parameters can be called to detect the monitoring parameters, thereby obtaining the detection results of the monitoring parameters. For example, when the monitoring parameters include temperature and pressure, the temperature sensor and the pressure sensor are called to monitor the temperature and pressure in the chemical reaction respectively, thereby obtaining the real-time monitoring results of the temperature and pressure.

[0049] In one possible implementation, in order to improve the accuracy of chemical reaction control, after obtaining the monitoring results of the monitoring parameters, the monitoring results will be subjected to at least one preprocessing operation including filtering, amplification, isolation and modulation and demodulation, so as to convert the current monitoring results into standard monitoring results, and then automatically control the chemical reaction through the standard detection results and the endpoint threshold.

[0050] After monitoring the monitoring results of the monitoring parameters, step S1300 is executed to automatically control the chemical reaction based on the monitoring results of the monitoring parameters and the endpoint threshold. Specifically, the following steps may be included:

[0051] First, a delay setting time is set to determine whether the current monitoring result meets the endpoint threshold.

[0052] First of all, it should be noted that each chemical reaction has an optimal reaction time. Too long or too short a time will affect the effect of the reaction. In order to ensure the adequacy of the chemical reaction, the delay setting time is set to the optimal reaction time of the chemical reaction. For example, if the optimal reaction time is 10 minutes, the delay setting time is set to 10 minutes.

[0053] Since the monitoring parameters are monitored at a preset frequency during the chemical reaction process, after the initial data of the monitoring parameters are monitored, a set time will be delayed, and after the set delay time, the current monitoring parameters acquired after the set delay time will be re-obtained, and then it is determined whether the current monitoring parameters meet the endpoint threshold.

[0054] Second, when it is determined that the endpoint threshold is not met, the actuator corresponding to the monitoring parameter is obtained, and a control instruction corresponding to the execution structure is generated, so as to control the actuator to perform a corresponding action through the control instruction to adjust the chemical reaction process.

[0055] It should be noted here that if the current monitoring parameter meets the corresponding endpoint threshold, it means that the chemical reaction has been completed within the most suitable time, and the operation of shutting down the chemical reaction will be executed. If the current monitoring parameter is not satisfied, it means that the chemical reaction has not been completed within the most suitable time. At this time, it is necessary to adjust the actuator corresponding to the monitoring parameter to perform the corresponding action, so as to adjust the chemical reaction. Among them, the actuator corresponding to the monitoring parameter is the actuator that can change the monitoring parameter. For example, when the monitoring parameter is temperature, the temperature of the chemical reaction can be changed by adjusting the heat medium regulating valve during the chemical reaction, and the actuator corresponding to the temperature is the heat medium regulating valve. For another example, when the monitoring parameter is pressure, the pressure of the chemical reaction can be changed by adjusting the vacuum pump during the chemical reaction, and the actuator corresponding to the pressure is the vacuum pump.

[0056] In a possible implementation, a third mapping relationship table is pre-stored in the system, and the third mapping relationship table records the mapping relationship between various monitoring parameters and corresponding actuators. In this way, when the monitoring parameters cannot meet the corresponding endpoint threshold, the actuator corresponding to the monitoring parameter can be found by querying the third mapping relationship table, and a control instruction for the actuator is generated. After receiving the control instruction, the actuator will perform the corresponding action, and after performing the corresponding action, the actuator will directly affect the corresponding monitoring parameter of the chemical reaction, so that the monitoring parameter meets the endpoint threshold as soon as possible.

[0057] In a possible implementation, the control instruction of the actuator is determined based on the difference between the monitoring result of the current monitoring parameter and the endpoint threshold. Specifically, when the difference is less than 0 (i.e., the current monitoring result is less than the endpoint threshold), a first control instruction for opening the actuator corresponding to the monitoring parameter will be generated, so as to control the actuator to open through the first control instruction, and then adjust the chemical reaction conditions through the opening of the actuator, so as to make the monitoring parameter meet the endpoint threshold as soon as possible. Among them, the execution structure can be a switch type mechanism (i.e., a mechanism that can only perform opening and closing operations, such as a switch valve). In the case where the actuator is a switch type mechanism, the first control instruction is received and the opening operation will be directly executed. The actuator can also be an adjustable mechanism (i.e., a mechanism that can be started according to a preset initial value, such as a regulating valve). In the case where the actuator is an adjustable mechanism, the first control instruction is received and it will be opened according to the pre-configured initial value.

[0058] Furthermore, in order to improve the control accuracy of chemical reactions, during the automated control process of chemical reactions, the time from the initial data of each monitoring parameter to the time when the corresponding endpoint threshold is met will also be recorded, and the time will be intelligently optimized to ensure that the time is within the most suitable reaction time for the chemical reaction. Specifically, the time T1 from the initial data of the monitoring parameter to the time when the final threshold is met, the initial value M of the actuator corresponding to the monitoring parameter, and the most suitable reaction time T2 for the chemical reaction are obtained, and the adjustment value P of the actuator corresponding to the monitoring parameter is calculated based on T1, T2, and the initial value M. The calculation formula for the adjustment value P is as follows:

[0059]

[0060] After calculating the adjustment value P, the next time the same chemical reaction is performed, the initial value of the execution structure corresponding to the monitoring parameter is set to P, and then the time for the monitoring parameter to go from the initial data to meeting the corresponding endpoint threshold is optimized by adjusting the initial value corresponding to the execution structure, so that it is within the most suitable time.

[0061] For example, the monitoring parameter is temperature. During the chemical reaction, the temperature rises from 30° to 80° for 20 minutes. The opening of the heat medium regulating valve is 50%. The most suitable heating time T2 needs to be controlled within 15 minutes. The calculation formula for the initial value of the heat medium regulating valve opening during the next reaction is as follows:

[0062]

[0063] Furthermore, in order to improve the control accuracy of chemical reactions, various monitoring parameters and chemical reaction conditions will be monitored in real time during the chemical reaction process, and corresponding monitoring data, reports, charts and other results will be generated. According to the set monitoring threshold, early warning and alarm will be issued for abnormal situations. When the monitored parameter object or environmental conditions are lower than or higher than the monitoring threshold, an alarm will be issued to remind the user to pay attention and take corresponding measures. The user can also view the system status in real time and adjust the corresponding endpoint threshold according to the results to control the chemical reaction based on the new endpoint threshold.

[0064] Combine the following Figure 2 Steps S1200 and S1300 of the present disclosure are described again. Figure 2 As shown, in addition to the material information module described above, the system for executing the disclosed method also includes a central processing module and an actuator module, and the central processing module also includes an online monitoring module, an online analysis module, a lean control module, and a prediction alarm module. The online monitoring module is used to determine the monitoring parameters of the chemical reaction based on the endpoint threshold, and to call the sensor corresponding to the monitoring parameter to monitor the monitoring parameter, obtain the monitoring result of the monitoring parameter, and send the monitoring result to the online analysis module. The online analysis module is used to perform at least one pre-processing operation of filtering, amplifying, isolating and modulating and demodulating the received monitoring result, so as to convert the current monitoring result into a standard monitoring result, and send the standard monitoring result to the lean control module. The lean control module is used to automatically control the chemical reaction based on the standard monitoring result of the monitoring parameter and the endpoint threshold. The prediction alarm module is used to monitor various monitoring parameters and chemical reaction conditions in real time during the chemical reaction process, and generate corresponding monitoring data, reports, charts and other results, and according to the set monitoring threshold, to warn and alarm abnormal situations.
