I. Introduction
No matter what culture, technology is a similar word It can refer to substances, such as machines, hardware or appliances, but it can also include a broader framework, such as systems, organizational methods and skills. It is the main body of knowledge evolution, shaped by society or society. The proliferation of new technologies such as computers makes people believe that technology is the decisive force of social evolution, in other words, the spontaneous driving force of change. It is best to abandon the reductionist view and regard technology as an integral part of a multi-directional social network that includes social, political, historical and economic factors.
Second, the origin of technology
Since the emergence of human society, human beings have been closely related to everyone and have never left! It's just that everyone has a clear feeling and recognition!
For example, the ancient technology of keeping fire was to burn dead trees hit by lightning or spontaneous fires in caves. It was not until Huo Xiangran invented drilling wood for fire that the way of life of human beings was greatly improved!
It can be roughly divided into the Stone Age, the Bronze Age, the Iron Age, the industrial revolution triggered by the steam engine, the highly civilized information age of 2 1 century, the space age and the ecological age!
Third, the basic definition of technology
Technology covers the symbolic things of the development level of human productivity, and it is the sum of survival and production tools, facilities, equipment, language, digital data, information records and so on!
For example:
The stone tools manufacturing skills and technology in primitive society have become a sharp weapon for human beings to deal with wild animals and slash-and-burn cultivation! Modern language can be said to be a stone tool technology platform!
This makes it easy to understand the basic definition and connotation of technology!
At the same time, technology can only spread, continue to communicate with operators! The carrier of technology is high-tech and high-skilled talents represented by craftsmen, technicians, engineers, manufacturing masters, inventors, scientists, management masters and information masters. Drawings, archives, various multimedia storage and memory components, computer chips, computer hard disks, etc. Ancient Oracle Bone Inscriptions, bamboo slips and printing are the symbol carriers of technological process!
Here, we can finally fill a long-awaited definition gap for the Chinese nation!
Fourth, the high development of technology leads to technical engineering.
Modern technology has gone far beyond the above concise meaning! It has become a complex, all-round and multidisciplinary technical project! The meaning will be more complicated!
Verb (short for verb) others
Because there are various views on the information understanding of the connotation and extension of technology, seemingly similar words such as technology, skill, skill, skill and technology belong to different links and details of engineering work!

[Editor] Science, Engineering and Technology
The difference between science, engineering and technology is not always unclear. Generally speaking, engineering pays more attention to practical experience, science pays more attention to theory and pure research, and technology is in between.
Generally speaking, science is a rational study or study of nature, focusing on discovering the eternal relationship (principle) between elements in the world. It usually uses rule-based technology, that is, a system of established procedural rules, such as scientific methods.
Engineering is the basic principle of science and technology. ......
What is technology?
technology
The original concept of technology is proficiency. As the saying goes, practice makes perfect, and skill is technology. Technology is far older than science. In fact, the history of technology is as long as that of mankind.
Broadly speaking, technology is the sum total of means, methods and skills created and developed by human beings to meet social needs. As social productive forces, the overall technical force of society includes technical skills, labor experience, information knowledge and physical tools and equipment, that is, technical talents, technical equipment and technical materials of the whole society.
The encyclopedia edited by French scientist Diderot gives a concise definition of technology: "Technology is a system of tools and rules that cooperate for a certain purpose." This technical definition basically points out the main characteristics of modern technology, namely, purpose, sociality and pluralism.
Any technology has a purpose from its birth. The purpose of technology runs through the whole process of technical activities. The realization of technology needs social cooperation, social support and various social conditions. These social factors directly affect the success or failure of technology and its development process. The so-called diversity means that technology can be manifested as tangible tools, equipment, physical materials and other hardware; It can also be expressed as intangible knowledge software such as processes, methods and rules, as well as information materials and design drawings. They are not matter but have material carriers. In modern technology as a material means and information means, skills have gradually lost their original position and role, but only an element of technology.
According to different functions, technology can be divided into productive technology and unproductive technology. Production technology is the most basic part of technology; Unproductive technologies, such as scientific experimental technology, public technology, military technology, cultural and educational technology, medical technology, etc. , is a technology to meet various needs of social life.
Generally speaking, the invention of technology is the materialization of scientific knowledge and empirical knowledge, which makes applicable theories and knowledge come true. The development of modern technology can not be separated from the guidance of scientific theory, and it has largely become a "scientific application". However, the development of modern science can not be separated from technology, and the need of technology often becomes the purpose of scientific research, and the development of technology provides the necessary technical means for scientific research. They are interrelated, promote and restrict each other. It can be predicted that their relationship will be closer and the boundaries will become blurred.
However, science and technology are two different social cultures after all, and the difference between them is also very obvious. The basic task of science is to know the world and make discoveries, thus increasing the wealth of human knowledge; The basic task of technology is to discover the world and make inventions to create human material wealth and enrich the spiritual and cultural life of human society. Science should answer the questions of "what" and "why"; Technology answers the questions of "what to do" and "how to do it". Therefore, scientific and technological achievements are different in form. Scientific achievements are generally manifested in concepts, laws, papers and other forms; Technical achievements generally appear in the form of process flow, design drawings and operation methods. Scientific products are not commercialized, but technological achievements can be commercialized. Modern technology has a strong utilitarian and commercial color.

Technical method is a practical method. People use technical knowledge and experience in technical activities, choose appropriate technical methods or create brand-new methods to complete established technical goals.
What are the five technologies?
A report released by McKinsey, a world-renowned consulting firm, lists 12 subversive technological changes, which will change life, business and global economy in the next 10 year, among which five technologies have contributed more than 1 trillion dollars to the global economy and will profoundly affect our future:
1. Mobile Internet
Mobile Internet technologies, including wearable devices, are developing rapidly. Since Apple introduced the iPhone in 2007, the sales of smartphones and tablets have increased sixfold. In developing countries, the mobile Internet can connect one billion people. By 2025, the economic influence of mobile Internet will be about 3.7 trillion to 10.8 trillion US dollars. In life, remote health monitoring can reduce the cost of treatment by 20%.
2. Automation of knowledge work
With the development of technology, some computers can "understand" the language used by ordinary people instead of accurate program codes, and people can obtain information without special training. This has completely changed the organization and execution of knowledge work, and some types of work can be fully automated. In the past five years, the number of users using intelligent software systems such as Siri and Google Now has increased by more than 400 million. By 2025, the potential economic impact of knowledge work automation will be 5.2 trillion to 6.7 trillion US dollars. In life, it is equivalent to increasing the full-time labor force 1. 1 billion to1.40 billion.
3. Internet of Things
Low-cost sensor networks for data acquisition, monitoring, decision-making and process optimization, the number of networked devices has increased by 300% in the past five years. The Internet of Things makes it easy for enterprises and public departments to organize and manage assets, optimize performance and create new business models. Through remote monitoring, the Internet of Things can also improve the health status of patients with chronic diseases and reduce the rising medical expenses. By 2025, the impact of the Internet of Things on the economy will be 2.7 trillion to 6.2 trillion US dollars.
4. Cloud services
Cloud has greatly improved Internet services, from search to streaming media, to offline storage of personal data (photos, books, music), as well as background processing capabilities. The cloud can also provide greater flexibility and responsiveness and even create a new business model. By 2025, the impact of cloud on the global economy will be about10.7 trillion to 6.2 trillion US dollars, which can increase productivity 15% to 20%.
5. Advanced robots
Robots with enhanced sensors, agility and intelligence can be used to perform tasks automatically. Now, due to the development of machine vision, artificial intelligence, machine-to-machine communication, sensors and actuators, the senses, agility and intelligence of robots are greatly enhanced, and robots are smaller, more adaptable and easier to deploy. New robots can replace humans in more manufacturing and service work, such as cleaning and maintenance. This technology can also make new surgical robots, robotic prostheses and "exoskeleton" supports to help patients improve and prolong their lives. From 2009 to 20 1 1 year, the sales volume of industrial robots increased by 170%. By 2025, the impact of robots on the economy will be $65,438+0.7 trillion to $4.5 trillion, which will improve the lives of 50 million amputees and people with mobility difficulties.
Summarize the point of view:
"By 2025, the value contribution of the five major technologies to the global economy will exceed 1 trillion dollars", which just reflects that in the era of knowledge economy, technological innovation will play the role of the main engine in the process of driving economic development, and patented technology will become the most important foundation for creating wealth.
What is technical work?
Technology is the work of research and development, drawing and programming, not the design of products.
What is detection technology?
Detection technology is a theory and technology to study information extraction, information conversion and information processing in automatic detection system, and it is one of the four pillars of automation technology. From the perspective of information science, the tasks of detection technology are: to find signals of various manifestations corresponding to natural information, and to determine the qualitative | quantitative relationship between them; Choose the most suitable expression from various signal expressions that reflect a certain information, and seek the best method and corresponding equipment for acquisition, conversion, processing, transmission, storage and display. The composition of the detection system A generalized detection system generally consists of an excitation device, a measured object, a sensitive element, a conditioning circuit and an output unit. The following figure is the composition block diagram of the automatic detection system. The characteristics of each part of the detection system are 1. Sometimes, in order to facilitate effective measurement, it is necessary to apply an excitation signal to the object to be measured, so that the object to be measured can be in a predetermined state and its internal relationship in the relevant direction can be fully displayed. 2. The characteristics of the measured object are all given in the form of signals, and the measured signals are generally dynamic quantities that change with time. Even when static quantities that do not change with time are detected, they are usually detected as dynamic quantities due to dynamic interference noise. 3. The sensing element converts the sensed measured value into a certain size and outputs it, usually an electrical signal. If it is not an electrical signal, it needs to be converted into an electrical signal by a conversion circuit. 4. The signal conditioning circuit generally has two functions, one is signal conversion and amplification, and the other is signal processing, that is, filtering, modulation and demodulation, attenuation operation, digital processing and so on. 5. There are many kinds of output devices, which can be configured as required. Modern detection system adopts computer and network technology, and sends the signal output by conditioning circuit directly to signal analysis equipment for on-line processing. In order to ensure the accuracy and stability of the measurement results, there should be a one-to-one correspondence between the output and input of the above links, and this relationship should not be distorted as much as possible.
What is the technology department?
As the name implies, it is the department responsible for technical work. According to the nature of the unit, the technical department of each unit is responsible for different work contents.
What is the general technology?
General technology (GT for short) refers to a wider range of technologies except information technology in senior high school curriculum, which embodies the foundation and universality and is different from professional technology. It is widely used in daily life and has a wide range of migration value for the development of students.
