In many aspects of personal growth, everyone will be exposed to papers to some extent. By writing papers, we can cultivate our ability of independent thinking and innovation. I believe that writing papers is a headache for many people. The following are my collected papers on modern chemical instruments and chemical automation control functions, which are for reference only and I hope to help you.
abstract:
With the continuous development of science and technology, the application of modern chemical instruments and their automation technology is more and more extensive. In order to give full play to the automatic control function of chemical instruments, the process control of this technology should be strengthened in practical application.
Key words:
Chemical instruments; Automation; process control
With the rapid development of science and technology, the degree of automation in various industries is gradually improving. In the chemical industry, the use of modern intelligent instruments has promoted the further development of the chemical industry. At the same time, the automation degree of the chemical industry has been continuously improved, the production efficiency has also been improved, and the labor intensity of employees has gradually decreased. The most important thing is that the safety and stability in production are effectively guaranteed.
1, the meaning and significance of modern chemical automation
Modern chemical automation mainly refers to installing some automation equipment in chemical production equipment to replace manual operation, so as to realize the automation process of production. With the continuous development of the national economy, the status of chemical industry in the national economy is gradually rising. In general, chemical production is carried out in a closed environment, which will have a certain impact on manual operation to a great extent. In addition, chemical substances have certain medicinal components, and their operating space is closed, so chemical production is also dangerous. In order to make chemical production more environmentally friendly, in the actual production process, it is necessary to comprehensively supervise all production indicators and control the corresponding data.
2, chemical instrument automation control function
2. 1 programmable function
In the actual design stage, chemical instruments can integrate advanced computing technology into traditional instruments, thus realizing the logic circuit conversion of traditional chemical instruments and making the original hardware system simpler. Especially for some chemical instruments with complex control circuits, the integration of computer technology can not only reasonably control automation software, but also effectively simplify the original circuit structure. The continuous development of intelligent system and the continuous application of chemical instrument design and development can not only improve the automation degree of chemical instrument, but also make chemical instrument gradually move towards manual and intelligent direction, improve the stability of chemical instrument, and contribute to the overall control of the system and the reasonable maintenance of actual instrument production.
2.2 Calculation function
In the stage of instrument design, technicians can realize the automation of instrument calculation with the help of microcomputer. This can not only reduce the actual labor intensity, but also have the calculation ability of complex data and ensure the accuracy of instrument calculation. During the operation of the instrument, ensure that the instrument can determine the maximum and minimum values. This can simplify the operation procedure of the instrument to a certain extent and reduce the actual manual labor.
2.3 Memory function
For ordinary instruments, there are usually only hardware facilities, which can only be used for short-term data storage and complete work records within a certain period of time, and it is impossible to realize excessive long-term storage of information data. In addition, they can not effectively store and control some complex loop control problems or data overload. At the same time, when new data appears, it will overwrite the original data information, which will bring difficulties to the recording and extraction of the original data. Combining the automation of the instrument with the microcomputer effectively can obviously improve the memory and storage function of the instrument, help the staff to query the original historical data information at any time, record the working state at different stages, and facilitate the staff to check the data information, thus further improving the actual production efficiency and laying a solid foundation for the later cost control work.
2.4 control function
The control ability of traditional instruments is relatively low, and generally only some simple data can be displayed. But at present, with the continuous development of science and technology and the gradual application of intelligent instruments, the automatic control ability of chemical instruments has also been significantly improved. At present, modern chemical instruments can properly control and process the data that traditional instruments can't handle. With the continuous improvement of instrument automation ability, the instrument's ability to cope with risks has also been effectively improved. At present, the instrument has realized the accurate logical judgment of complex process and the reasonable evaluation of production conditions, so as to take corresponding risk control measures, reduce the actual production risks, and finally achieve the purpose of safe production, which is conducive to the improvement of actual production efficiency.
2.5 Automatic fault monitoring
The instrument can display and record the data information of the whole chemical stage. Traditional chemical instruments mainly use hardware facilities, so it is difficult to display the fault location information flexibly. However, due to the new technology and high-end microcomputer processing system, automatic instruments can accurately locate the actual location of faults and find fault data information, which brings great convenience to the actual troubleshooting work. With the advantages of automation, it can not only save maintenance time, but also improve the actual efficiency of chemical production to a certain extent. So as to ensure that instrument inspectors can take the overall situation into consideration, grasp the actual state of chemical production and possible failures in time, take effective measures to solve practical problems in time, avoid further deterioration of failures, and ensure the safety and stability of modern chemical production.
3. Development prospect of chemical instruments
In order to ensure the stability, safety and reliability of chemical instrument production, it is necessary for the government and other relevant departments to increase their support for chemical production and formulate a set of relatively perfect scientific management mechanisms and laws and regulations. At the same time, in view of the actual production management and present situation of chemical enterprises, the government and other departments should increase their intervention to ensure the stable and all-round development of the chemical industry, so as to gradually improve the automation degree of chemical production, ensure the safety of actual production and avoid the waste of some personnel and funds.
4. Conclusion
To sum up, with the continuous development of chemical instruments and the gradual expansion of application scope, it is very important to do a good job in modern chemical instruments and chemical automation control. In order to study it deeply, it is necessary to combine modern chemical theory with practice and make a comprehensive analysis and exploration of the specific control system. In addition, based on the operation of chemical machinery, it is necessary to deeply analyze the automatic control of chemical instruments.
