In the next few years, China's economy will face transformation, which is inseparable from energy conservation and consumption reduction. The improvement of energy efficiency should be realized through automation. In addition, in terms of high-end equipment manufacturing, it is mainly to improve the automation level in order to achieve the purpose of energy conservation and emission reduction. Therefore, the automation market will grow explosively in the future. According to the relevant report of IMS research department recently released by ihsinc. (NYSE: IHS), it is predicted that the relative strength of the Chinese and American markets in 2012 will promote the growth of the global industrial automation market by 9.5% to US $159.8 billion. It is predicted that the global industrial automation market will exceed US $200 billion by 2015. The development of automation market has driven the development of ultrasonic extractor industry.

The development trend of automation technology is systematization, flexibility, integration and intelligence. According to this track, automation instruments will show the following development trends: ① the control goal will develop from realizing the stable operation of process parameters to the optimal control with the optimal quality as the index. ② The control method is developed from analog feedback control to digital open-loop predictive control; From the traditional manual constant value regulator, PID regulator and various sequence control devices, it has developed into a digital regulator and adaptive regulator Snowflake Ice Maker composed of micro mechanism.

Automation is a comprehensive science and technology involving many disciplines and widely used. From the application point of view, the research contents include process automation, mechanical manufacturing automation, management automation, laboratory automation and home automation. In these categories, in addition to management automation, other types are closely related to instruments and meters, such as control, detection and display instruments required in process automation, precision measuring instruments in mechanical manufacturing automation, detection and laboratory instruments in laboratory automation, building related instruments in home automation, and ultrasonic extractor manufacturers.

The development of modern production and science and technology not only puts forward higher and higher requirements for automation technology, but also provides necessary conditions for the innovation of automation technology. After the 1970s, automation began to develop towards complex system control and advanced intelligent control, and was widely used in various fields such as national defense, scientific research and economy to realize larger-scale automation, such as the integrated automation system of large enterprises, the national railway automatic dispatching system, the national power network automatic dispatching system, the air traffic control system Urban traffic control system, automatic command system, national economic management system, etc. The application of automation is expanding from engineering field to non engineering field, such as medical automation, population control, economic management automation and so on.

According to the 12th Five Year Plan for the development of instrument industry, by 2015, the total output value of the industry will reach or close to trillion yuan, with an average annual growth rate of about 15%; With an export of more than US $30 billion, we will accelerate the development of advanced automatic control systems, large-scale precision testing equipment, new instruments and sensors, mainly focusing on the needs of major national projects, strategic emerging industries and people's livelihood. At the same time, it has basically completed the autonomy of typical equipment control systems in petrochemical, thermal power, nuclear power, wind power, rail transit and other fields, and basically met the needs of snow ice maker manufacturers in key fields represented by environmental protection, food and drug safety and public safety treatment of emergencies.
