Anonymous users2024-02-06Summary. Hello, glad to answer for you.
At present, the main development direction of sensor technology is the basic research of the sensor itself, and the second is the combination with the microprocessor
The development process of sensors can be roughly divided into the following three stages:
Phase 1: Structural sensors.
The structural parameter changes are mainly used to sense and transform the signal. For example, the resistance strain gauge sensor uses the change in resistance of the metal material when it undergoes elastic deformation to convert the electrical signal.
Phase 2: Solids sensors.
Developed in the 70s, these sensors are made of solid elements such as semiconductors, dielectrics, and magnetic materials, and are made using certain properties of materials. For example, the thermoelectric effect, Hall effect, and photosensitive effect are used to make thermocouple sensors, Hall sensors, and photosensitive sensors.
Phase 3: Smart Sensors.
Developed in the 80s, the so-called intelligent sensor refers to its ability to detect, self-diagnose, data processing and adapt to external information, and is the product of the combination of microcomputer technology and detection technology. In the 80s, intelligent measurement was mainly based on microprocessors, and the sensor signal conditioning circuits, microcomputers, memories and interfaces were integrated into a chip, so that the sensors had certain artificial intelligence.
At present, the main development direction of sensor technology is the basic research of the sensor itself, and the second is the combination with the microprocessor
Hello, I am inquiring for you here, please wait a while, I will reply to you immediately
Hello, glad to answer for you. At present, the main development direction of sensor technology is the basic research of the sensor itself, and the second is the combination with the microprocessor: the development process of the sensor can be roughly divided into the following three stages:
The first stage: the structural sensor mainly uses the structural parameters to sense and transform the signal. For example:
Resistance strain sensor, which uses the change of resistance when the elastic deformation of metal materials undergoes to convert electrical signals. The second stage: solid-state sensors have been developed since the 70s, which are composed of solid elements such as semiconductors, dielectrics, and magnetic materials, and are made by using certain properties of materials.
For example, the thermoelectric effect, the limb annihilation Hall effect, and the photosensitive effect are used to make thermocouple sensors, Hall sensors, and light-sensitive sensors. Stage 3:
Intelligent sensors were developed in the 80s, and the so-called intelligent sensors refer to their ability to detect, self-diagnose, process and adapt to external information, and are the products of the combination of microcomputer technology and detection technology. In the 80s, intelligent measurement was mainly based on microprocessors, and the sensor signal conditioning circuit, microcomputer, memory and interface were integrated into a chip, so that the sensor had a certain artificial intelligence.
I hope the above is helpful to you If you are satisfied with me, please give me a thumbs up
At present, the main development direction of sensor technology is the basic research of the sensor itself, and the second is the combination with the microprocessor, right or wrong.
Hello, glad to answer for you. That's right.

b.Improve sensor performance and detection range.
c.Miniaturization and micropower consumption of sensors, integration.
d.Multi-functionality, digitization and networking of sensors.
Correct answer: develop and use new effects and develop new materials; Improve the defect resistance and detection range of the sensor; Miniaturization and micropower consumption of sensors, integration. The multi-function of the sensor is noisy, digitized and networked.

Anonymous users2024-02-04The following is a list of relevant information on the impact of sensing and detection technology on research directions.
The status and role of sensing and detection technology.
Sensing and detection technology is not only an indispensable technology in mechatronics, but also a key link to achieve automatic control and automatic adjustment. To a large extent, the detection technology of sensors affects the quality of automation systems. In an automated system, only by using the detection technology of the sensor to check all aspects of the parameters can the entire automation system work normally.
In today's rapid development of science and technology, detection and sensing technology can be used in both life and production. For example, some instruments and equipment, office equipment, computer inheritance manufacturing systems in home appliances, CNC machine tools, large generators, and so on.
In the national defense industry and equipment, sensing technology also plays an important role. It can be seen that sensing and detection technology has promoted the development of social productivity and science and technology in improving the safety and economy of production equipment and systems, monitoring and testing methods, and controlling product quality.
In general, from the universe to the land, from the land to the sea, from the top.
From technology to basic knowledge, from complex large-scale automation equipment to every detail in society, sensing and detection technology veterans play an important role.
The development direction of China's sensor technology.
1. The development of precision. In the original. On the basis of research, a sensor with more sensitivity, accuracy and flexibility is developed.
2.The development of reliability. The temperature resistance, pressure resistance, and anti-interference performance of the excitation sensor are the key factors that affect the reliability of the sensor, so we should pay attention to these factors to enhance the reliability of the sensor.
3.Miniaturized development. Strive to develop better materials and technologies to make sensors.
The ideal of miniaturization becomes a reality.
4.Energy-saving development. The work of the sensor is based on the power supply, which is both energy-intensive and time-consuming. Therefore, we should strive to develop sensors that do not rely on power supply.
Make by learning.
bai my thoughts. >>>More
In fact, now the project cost is generally recruited to have three to five years of work experience, because novices are inexperienced and easy to make mistakes, and the recruitment company is also afraid of spending two or three years to train out of the newcomer to jump ship, resulting in a waste of resources of the enterprise, for the newcomers who have just graduated, they do not necessarily have to do the cost, you can first go to the construction unit or supervision unit to do a period of time to be familiar with the construction site and construction technology, increase the construction experience will be very helpful to do the cost in the future, If you have to do the cost, then go to the local talent market to see, or through the relationship between family and friends and classmates, it is not easy to find it in winter, it is easy to find a job next spring, you can take a certificate first after graduation, maybe it will be useful to find a job, I hope it can help you.
Are you in your third year of junior high school?
I'm going to write about it too. Many parents love their children very much, because we have only one child in almost every family here, parents think that spoiling and protecting their children is the concern, but do you think that a bird in a cage, whether it is really happy, although it does not worry about eating and drinking, but when it sees other birds flying freely in the blue sky, it will also feel happy and proud of its "unearned gains, food to stretch out your hand, to open your mouth"? In fact, we children are like the little bird in a cage that can't fly into the blue sky, although we are called "little emperor" and "little princess". But we don't have the right to be emperors and princesses, because we are caged birds, so we have lost the ability to fly into the blue sky. >>>More
Praise be to you, great scientist! Your miraculous and glorious life is something we admire infinitely. >>>More
