Which is better, communication engineering or automation?

Communication engineering is better. Communication engineering Communication engineering is a discipline that studies and applies communication technology, mainly involving the knowledge of signal transmission, communication network, wireless communication and other aspects.

Automation and communication engineering are very different in terms of professional background and career development. If you are good at digital circuits, control and embedded design, automation engineering is a very good choice; if you are interested in networks, cellular networks, communication protocols, etc., you can choose communication engineering.

Automation may be better. The top ten best majors for science students: electrical engineering and its automation, computer majors, mechanical design and manufacturing and its automation, electronic information engineering majors, communication engineering majors, automation majors, water supply and drainage engineering majors, statistics majors, medical majors, and normal majors.

Power system automation neutr station andWhat kind of communication method is the main station?

It is mainly used to realize the communication between the distribution station and the main station, and it can also be used for the communication between the 10kV opening and closing station, the small cell transformer and the power distribution main station; (4) Satellite communication is to use a communication satellite in a synchronous orbit as a relay station to forward or reflect radio wave signals, on the ground Communicate between faces.

Common communication methods are mail, telephone, fax, satellite telephone, telegram, data communication, etc. Theoretically, full-duphuang transmission can improve network efficiency, but in fact, it is still useful to cooperate with other related equipment.

CAN bus (controller LAN): CAN bus is a powerful and reliable communication protocol widely used in automotive and industrial applications. It allows real-time data transmission and supports error detection, making it suitable for the battery management system.

The main communication methods of the electricity information acquisition system include optical fiber private network communication, GPRS/CDMA wireless public network communication, 230MHz wireless private network communication, power line carrier communication, RS-485 communication mode, etc.

Advantages of ordinary microwave communication: a wireless communication method with large transmission capacity, high quality and flexible configuration. It is widely used in substations with power systems above 220kv. Disadvantages: This communication method has high environmental requirements. The construction of an ordinary microwave communication network requires on-site survey and design, so the total construction cost is also very high.

PROFIBUS: It is a non-deterministic communication between PROFIBUS main stations. PROFIBUS DP is mainly used for deterministic communication between the PROFIBUS master station and its remote slave station, but it still allows communication between the master station and the master station.

Which is better for communication engineering or automation

From the perspective of employment, automation is more important than communication. Almost automation with two related words in engineering can apply for the job.

Employment market and salary level: Communication engineering, electrical engineering and its automation all belong to high-tech fields. The employment market is relatively good, but the specific employment situation is also related to the economic development of the region and industry.

Compared with communication engineering and automation, automation majors are more employed and have broader prospects! Graduates majoring in automation have a wide range of employment channels, because automation technology is widely applied, and its employment field is also designed in various fields.

evenIn many schools, it is not as good as telecommunications engineering, but it is relatively popular in the middle of postgraduate study, and the employment position is relatively good. The employment rate of automation is the best in the whole electrical category, because it is a combination of mechanical and electronic major, but the salary is relatively close to that of machinery, that is, it will be relatively lower. You see for yourself.

If you go to Beijing Post, the communication is naturally good. If you go to Harbin University of Technology, the machinery is good. This is on Baidu..

The introduction of electrical engineering and its automation and communication engineering is as follows: Electrical engineering and its automation and communication engineering are good choices. Electrical engineering has a wide range of employment, and you can go to the State Grid and Internet companies; communication engineering has a wide range of employment, and you can go to the three major operators.
