Abstract: With the rapid development of social economy, higher demands have been put forward for chemical production. Chemical production is more seeking intelligence and automation, and automation needs are mainly displayed in the automation level of instruments and controls. The main types, application value and main functions of chemical production control automation instrument are analyzed.
Introduction
With the continuous development of my country's chemical production industry in recent years, chemical production is closely related to people's daily lives, and various production activities are inseparable from chemical production. The use of automated instruments can effectively supervise various production processes, thereby promoting the stable and rapid development of the chemical industry. Therefore, people's demand for chemical automation instruments is gradually increasing.
Introduction to the automation instrument of chemical production control
.1 Classification of chemical production control automation instruments
can be divided into the following three types according to the different instrument composition form: component assembly type, base type and unit combination type, etc. Among them, base instruments are designed for the corresponding scope measurement needs. A scale is installed in this instrument equipment to directly display the measurement results. The defects it has to be difficult to achieve strong versatility; however, the key performance characteristics of unit combination instrument facilities are that they can better meet general requirements; assembled instruments rely on the application of electronic components and circuits, and then connect the corresponding facility plug-ins, and then the instrument equipment corresponding to the components according to specific application needs. At this stage, based on the computer control system, this type of instrument has become the first choice.
2.2 Important value of the use of chemical production control automation instruments
Chemical production refers to the use of some automation devices in chemical equipment to replace previous manual labor, and automation instruments play a very important role in the chemical automation production process. The use of automated instruments is not only conducive to strengthening the work efficiency of chemical production, but also under its supervision, many complicated problems can be solved in a timely manner. Chemical instruments occupy a major position in the automation of chemical production. If chemical instruments are lost, a large number of production steps cannot be successfully implemented. The use of chemical instruments can continuously record and regulate various production data, and can also calculate the generated process, thereby providing guarantees for the effectiveness of all production processes and promoting the strengthening of chemical production quality. If the automated instrument finds that the setting parameters are inconsistent with the specific data, it can also adjust it by itself, and call the alarm by itself when there is a serious problem with the data. In this way, the accident can be reported and dealt with in the first time, reducing the company's production losses to the lowest level. Therefore, it is very important to use automated instruments in the chemical production control process, and it is necessary to attract the attention of chemical enterprise managers to
3 The development status of automated instruments for chemical production control
After the 1940s, automated instruments were developed. Due to the influence of technological factors at that time, the first automated instrument at that time had poor accuracy and large volume. After the 1960s, with the continuous development of science and technology, automated instruments at this time have improved greatly. The accuracy level has gradually increased and the volume has gradually decreased. It has fully integrated computers to process data, enhancing work efficiency to a certain extent. By the 1970s, automated instruments had been very practical. With the gradual improvement of technological level, a large number of emerging technologies and high-tech products were used. Automated instruments gradually began to enter microcomputers, microprocessors, and microsoftware, which made them have more functions. The work efficiency of the enterprise's chemical production links has been greatly improved. A large number of chemical enterprises have gradually regarded automated instruments as common facilities in the chemical production process.With the rapid advancement of computer technology, automated instruments will also develop rapidly. The current application scope of automation technology is extremely wide, such as pneumatic instruments, electric instruments and digital instruments. Automation devices have entered all areas of the chemical industry and are an indispensable equipment for the chemical industry. They can efficiently promote the strengthening of chemical production efficiency and thus promote the construction of my country's national economy.
4 The main functions of chemical production control automation instruments
first, programming function. The application of computer software in instrumentation equipment can gradually replace most hardware logic circuits, especially the bit control characteristics of some interface chips used in control circuits can implement a more complicated control function. Programming of this kind of software is extremely simple, but if other hardware is used instead, it is necessary to have corresponding timing and control circuits. Therefore, using computer software in instrumentation equipment can greatly simplify the hardware structure and remove general circuit circuits, thereby making the product design more scientific and compact.
second, calculation function. Since microcomputers are installed in the chemical production control automation instrument, a large amount of data can be implemented with extremely complicated calculations. In chemical production control automation instruments, it is usually necessary to perform multiplication and division calculations on some constants to clarify the calculation and comparison of more complex data such as extreme and minimal values.
3, save memory function. Since the random memory provided by the microcomputer in the chemical production control automation instrument has the ability to store and remember, it can not only remember the information in the previous state, but also store it all the time. It can also memorize more state information, and then process and reproduce it, so that the memory function of the chemical production control automation instrument will not be affected by power outage, which is impossible to achieve by traditional instrument equipment.
5 Conclusion
With the continuous development of modern enterprises, it also promotes the rapid development of society. The networking, intelligent and bus-based operation methods of automated instruments in chemical enterprises have created a new production landscape for enterprises. This technology is widely used in the production process of chemical enterprises, and promotes the rapid and sound development of chemical enterprises.
