Laboratory intelligent reaction system and its control method

Abstract

The invention discloses a laboratory intelligent response system and a control method thereof. The system comprises a reaction device, an automatic control device and a central monitoring platform, wherein the reaction device is connected with the automatic control device; the automatic control device is connected with the central monitoring platform by virtue of a communication interface. The control method of the laboratory intelligent response system is a design method for selecting a suitable chemical reaction system from an experimental design method library. The control method comprises the following steps: setting corresponding experimental process parameters and transmitting the corresponding experimental process parameters to corresponding controllers, automatically controlling reaction process parameters, collecting and sorting experimental data, and analyzing the data by selecting a corresponding analysis method from an experimental data analysis method library after the experiment is ended. By virtue of the laboratory intelligent response system, integration for designing experiment, controlling experimental processes and processing experimental results is realized; the influence on the experimental processes caused due to manual operation is reduced to the maximum limit; an optimal experimental condition combination is quickly found; the experiment time is shortened; the experiment efficiency is improved.

Description

technical field [0001] The invention relates to an intelligent response system, in particular to a laboratory intelligent response system and a control method thereof, belonging to the technical field of automatic control. Background technique [0002] In the research and development process of pharmaceuticals, polymer materials, chemical intermediates and other products, the reaction device is the core. Usually, various reaction materials are added to the reaction device during the research and development process, and the peripheral conditions are controlled by adjustment, such as flow rate and material distribution. Ratio, temperature, pressure, reaction time, pH, etc., to carry out chemical reactions to generate target products. However, with the continuous improvement of market requirements for products, the protection of patents on product form or crystal form makes the following defects appear when there are various external factors that affect the performance of the ...

Problems solved by technology

[0003] 1) High labor intensity, low degree of automation, and long R&D cycle: In the material industry, to obtain a product with an optimal formula, it is necessary to continuously conduct a large number of repetitive tests in the laboratory and compare evaluation parameters to determine the optimal formula. The best product formula, and at present, a large number of repetitive experiments are carried out through manual experiments, the results of each experiment are recorded, and the results of multiple groups of experiments are compared to obtain the best product formula. The whole process of experimentation is intensive. Many influencing factors and low efficiency

[0004] 2) The process control accuracy is low: People often use the unit combination instrument to realize the automatic control of the reactor, but it is difficult for the craftsman to realize the precise control of each process index through the unit combination instrument, and it is very easy to cause production failure due to untimely operation. Stability or the occurrence of accidents

[0005] 3) Stability and reproducibility are poor, and human interference has a great influence on the experimental results: because many reactor feeds are still controlled manually or semi-automatically, affected by the level of operators, different operators of the same formula conduct experiments, and the results obtained The results are quite different
