Problems Needing Correct Understanding in Instrumentation Business

This site2017-04-07 14:48:28

What is the status and role of instruments in the national economy? In the past, we often said that the development of industrial production is inseparable from it, and scientific research is inseparable from it. Advanced instruments represent the country's scientific and technological level. Today, it is necessary to look at the status and role of instruments in the national economy from a higher and more comprehensive perspective, because it not only affects the implementation of two fundamental transformations, the revitalization of the country through science and education, and sustainable development. The information age has also played a profound role. The overall level of instruments is also one of the signs of comprehensive national strength. This is a problem that must be correctly understood in the instrumentation industry as the times advance.

 

What is an instrument? In a nutshell, instruments are tools for understanding the world. From the perspective of human social development, improving productivity is the decisive factor. “科学技术是第一生产力”的科学论断,说明科学技术是发展生产力的首要因素。 Combining with the contemporary social development situation, Comrade Xiaoping put forward the scientific assertion that "science and technology are the primary productive forces", which shows that science and technology are the primary factor for the development of productive forces. In this way, science is the knowledge that knows the world, and technology is the knowledge that transforms the world. The two are interconnected, promote each other, and cause and effect each other, thus forming the primary productive force. The realization of productivity depends on means of production and tools. The tools for scientific research are mainly instruments, while the tools for achieving technology depend on machines. It can be understood that the instrument is a tool for understanding the world. In contrast, machines are tools to transform the world. The instrument plays the role of expanding and extending the human sensory nervous system, enhancing the ability to understand the world, and the machine replaces and extends human physical labor. It is important to reshape the world on the premise of knowing the world.

 

There are two aspects to understanding the world, one is to explore the laws of nature and accumulate scientific knowledge; the other is to understand the situation on the production site to guide production. Because knowing the world is as important as transforming the world, and knowing the world is often the precursor to transforming the world, instruments and machines are also important. Under certain conditions, instruments are also material precursors to production. Scientific research results of many important instruments in history often bring about a leap in productivity.

 

Today, the world is entering the information age from the era of industrial mechanization. The characteristic of this era is to extend the human brain function with the computer as the core, and to play the role of expanding human brain labor, so that human beings are going out of the mechanization process and entering the era of expanding human sensory nervous system and mental intelligence by physical means. At this time, the role of the instrument is mainly to obtain information as the basis for intelligent action.

 

The function of the instrument lies in the physical, chemical or biological methods to obtain information about the movement or change of the detected object. In scientific instruments, this information is often a quantified manifestation of the movement of matter. This method of detecting material is often called a sensor.

People use the information (information acquisition) thus obtained through instrumentation or computers to perform selective conversion or analysis (information conversion and processing), making it a quantified form that is easy for people to read and identify (information display, conversion, and use). , Or further signal, image, through the display system, to facilitate observation, into the inventory file or directly into the automated intelligent operation control system. When it comes to the content of information technology, the important significance lies in that instruments and meters are the source of information, mainly sensors. A major trend in the development of modern instruments is the combination, and the information processing, conversion, storage, and display in the instrument are directly connected with information technology. Only sensors are ever-changing, large and small, ranging from the simplest to the most complex, and diverse. ——加速器可大到公里级。 For example, a temperature probe can be as small as a needle tip, while an elementary particle detection system , the accelerator, can be as large as a kilometer. In today's prosperous information technology era, the functions of the instrument are more reflected in the detection element-the sensor.
