For the electrician to take 3,000, the electrical engineer to take 30,000?

For the electrician to take 3,000, the electrical engineer to take 30,000?
“Electrical Engineer” refers to the technical personnel engaged in the design of electrical systems. It is a professional title and a professional technical level. If it is an operator, it is called an "electrician."
Electrician newcomer: First of all, do the miscellaneous, help the old electrician to be the guardian, hand the tool, take the multimeter, put the cable, lead the material, do the start time is almost 1-3 months (this is related to your learning ability, interpersonal relationship, some masters I teach more, and naturally I learn more.)


At the beginning, it is the time when you and your colleagues get together. After the internship time, the master will arrange some, connect the socket, repair the workshop lighting, check the simple motor forward and reverse control, self-protection circuit failure, replace the switch, contact Devices, limit switches, etc., let you touch some simple circuits, cultivate your independent maintenance ability and courage.


Why do you have courage here? Because electricity is a dangerous substance after all, it can't be seen, and it can't be touched. One second can abolish one person, so it will always be safety first.
Formal electrician: Work tends to be hands-on (of course, have to brain), repair equipment related to electricity.


For example: lighting, lathes, stereos, electric stoves, etc.


The focus is on hands-on installation, commissioning or repair of electrical equipment.
Electrical Engineer: Work tends to be brainstorming (of course, it must be done). The work of electrical engineers is mainly the formulation of electrical construction plans. Electrical engineers need to deal with general quality problems in the construction process in time to design drawings and develop new products. New technology, guiding production, commissioning, supervision, inspection of electrical construction on the construction site, on-site installation and commissioning of electrical equipment, analysis and handling of field equipment and other related equipment priorities.
Electrical engineer and electrician:


Electrician: A person who is engaged in the installation, commissioning, maintenance, and repair of mechanical equipment and electrical system wiring and components.


Electrician technician certificate: Professional qualification certificate for working as an electrician.


Electrical engineer: refers to engineers in the fields of electric power, electrical, electrical equipment, electrical automation, electromechanical, mechanical and electrical integration, etc. It is a professional title, which is a title different from electrical technicians, assistant electrical engineers, and senior electrical engineers.


What is the difference between the two?


1. The electrical engineer belongs to the engineering and technical personnel sequence and has the technical title certificate; the electrician technician belongs to the engineering and technical worker sequence and has the grade certificate;


2. The electrical engineer belongs to the intermediate title of the engineering and technical personnel sequence; the electrician technician belongs to the high-tech level of the engineering and technical worker level, which is equivalent to the former;


3, electrical engineers focus on theoretical knowledge; electrician technicians focus on hands-on ability in practical operations;


4. The classification and surface of the electrical engineer should be much wider;


5, work is not the same


6. The level of education is different. Electrical engineers are generally trained in systems of higher education and are aimed at professional goals. Electrical technicians are generally professionals with lower cultural levels, and the level of work they perform is generally poorer;


7. The issuing unit is different. The electrical engineer is a professional technical qualification and belongs to the intermediate professional title. The issuing unit is the Personnel Bureau or the Personnel Department. It belongs to the cadre series. The electrician belongs to the vocational skill qualification and belongs to the intermediate vocational skill. The issuing unit is the labor bureau and belongs to the worker series.


The electrician technician certificate and the electrical engineer certificate are the professional qualifications of the skilled electrician, and the other is the representative document of the electrical engineering design and management level title. One is for first-line skilled workers, and the other is for high-end talents who design, manufacture, and manage the industry. So what if you become an electrical engineer from an electrician?


[capacity characteristics]


1. PLC control programming and debugging can be performed by computer.


2, can use the computer to draw CAD electrical schematic drawings.


3, according to the design requirements of the drawings, skilled use of electrical tools, wiring and installation of electrical equipment.


4, according to the requirements of electromechanical system control, on-site programming, debugging.


5, can quickly design solutions according to customer requirements.
Advanced Level 1: Growth Stage


1, learning programming software: master one or a variety of PLC programming software and products. For example: CODESYS, CPX-CEC, CECX, CECC


2. Electrical CAD drawing software learning: According to the customer's requirements for electromechanical system control, the system electrical schematic diagram is designed according to industry standards. Example: EPLAN


3, touch screen software programming configuration: high-end human-machine interface gives customers a high-tech feeling. For example: CDPX, Design Studio


4, electrical control cabinet line installation


5, on-site debugging: analyze the cause of the system failure to eliminate the fault. It requires long-term practice and accumulation, and it requires constant diligence and study and a love for the industrial control industry.


To move to a true electrical engineer position requires the first three basic capabilities. When the newcomer just entered the factory, I don't know how to get started to understand the principle of equipment control. PLC programming is not proficient. I can't find the model of the component on the Internet. The electrical drawings have not been understood for more than half a month. Even for half a year, I want to change my working environment.


Therefore, to engage in the industrial control industry, we must strengthen our choices, "find the right way, the next medicine", a little bit on yourself.


Advanced Level 2: Ability Breakthrough


1. If you are an electrical engineer in your own company, you only need to be familiar with the electrical equipment of your company.


2, if it is to serve customers, then just familiar with a PLC product is not enough. The more skills you master, the more you experience and experience.


3. If you want to become a senior electrical engineer, you need to learn hydraulic pressure transmission, frequency converter speed control, servo drive and so on. These can be slowly learned and accumulated in the actual work of the project.


Advanced Level 3: Outstanding Stage


1. Proficient in the process


For example, in boiler control systems, the drum level is an important control parameter that reflects the balance between boiler load and feed water.


If the steam drum liquid level is too high, the steam water will be unfavorable to the operation of the superheater and affect the separation effect of the steam and water. If the liquid level is too low, the boiler water circulation will be destroyed, affecting the operation of the economizer, and it is easy to cause the water to completely vaporize and burn the boiler or even explode.


In addition to the normal factor of heating vaporization, there are fluctuations in steam load and feed water flow. When the load suddenly increases, the steam drum pressure suddenly drops, the water will rapidly vaporize, and a large number of bubbles appear, forming a "false liquid level."


For this reason, in the design of the control scheme, the three-pulse control of liquid level, steam and feed water is often used. If you don't know the process, use a simple level control system. Once a “false level” occurs, it will affect production and even cause danger. Therefore, automation engineers must work hard on the process to be proficient in the process.


2, choose the right network


For an automation project (especially for medium and large-scale control systems), it is very important to choose a network. Some people even put forward the concept of "network is a controller", so be familiar with various industrial bus and Ethernet protocols.


First, the network must be open to facilitate the integration of different devices and the expansion of future system scales;


Secondly, the form of the network is selected according to the transmission performance requirements of different network levels, which must be carried out under the premise of a deeper understanding of the protocols and mechanisms of the network standard;


In addition, comprehensive consideration of system cost, equipment compatibility, site environment applicability and other specific issues to determine the network standards used at different levels. The performance of a real-time system can be measured in terms of time, reliability, and application objects.


3, master the principle of PLC scanning


Compared with other control devices, the most important feature of PLC is "scanning".


After the PLC is powered on, the program scan and I/O scan are automatically repeated, that is, input sampling, user program execution, and output refresh. Completing the above three phases is called a scan cycle.


During the input sampling phase, the PLC reads all input states and data in turn in a scan mode and stores them in the corresponding cells in the I/O map area.


After the input sampling is finished, it is transferred to the user program execution and output refresh phase. Even if the input status and data change, the status and data of the corresponding unit in the I/O image area will not change.


In the user program execution phase, the PLC sequentially scans the program (ladder) in order from top to bottom, first left and then right, and refreshes the state of the corresponding unit of the RAM memory area or the I/O image area according to the result of the logic operation.


In the output refresh phase, all the output latch circuits are refreshed according to the corresponding state and data in the I/O map area, and then the corresponding peripherals are driven by the output circuit. At this time, the real output of the PLC is.


It can be seen that the process and result of PLC program control are different from the relay logic circuit, especially the sequence of the step, the capture of the pulse signal, etc., which are closely related to the scanning principle of the PLC. In practice, a large number of procedural problems originate from this, often with incredible results. Therefore, to design a PLC program, you must be proficient in the basic principles of PLC.


4, strive for structured programming


It is the goal of every programmer to improve the quality of the program, improve the programming efficiency, and make the program have good readability, reliability, maintainability and good structure.


IEC61131-3 is a standardized programming language for industrial control introduced by the International Electrotechnical Commission (IEC) in 1999. It is open, portable, structured and structured, and has excellent error detection and error correction capabilities. For PLC programming.


Structured programming makes it easy to build programs (especially complex programs), multi-person design, debugging, and software management. Although the idea of software engineering has been accepted by most programmers, it is not easy to translate this idea into conscious behavior in the software development process.


5, attach importance to anti-interference measures


The application of automation systems to harsh industrial sites is particularly important. In practice, there are often instances where debugging fails or even equipment is damaged due to interference. There are three types of sources of interference from automated systems:


1) Space radiation interference;


2), the external circuit of the system, including the interference introduced by the power line, signal line, grounding system, etc.;


3) Electromagnetic radiation and line interference inside the system.


In response to these disturbances, the following measures should be considered in the implementation of the project:


1) Full consideration of environmental adaptability and electromagnetic compatibility in system structure design and equipment selection;


2) Use a power supply with excellent performance to suppress interference introduced by the power grid;


3) Reasonable selection and laying of cables and wires;


4), using isolation or filtering means on the hardware;


5), measures to improve reliability, such as digital filtering, timing correction reference point potential, information redundancy, etc.;


6), correctly select the grounding method, generally use one point of grounding and one point of grounding in series.


Now I know why electricians and electrical engineers only have three words difference, but the difference in wages is one hundred and eighty thousand. If there is pay, there will be a return!
