What is an electrical engineer?


Friends who have been to the equipment commissioning site, you often see a person, curled up and squatted on the table, staring at the laptop screen, sometimes looking at the rotating machine, sometimes moving the mouse to the keyboard, and sometimes wiping the sweat of the forehead ......


Congratulations, the person you saw is an electrical engineer.


In the automation industry, electrical engineers and mechanical engineers cooperate with each other. Mechanical engineers complete the design of mechanical parts, and the calculation of specific aspects, coordination between mechanical parts, speed, pressure, temperature, time, torque, etc. All need an electrical engineer to complete. It can be said that the mechanical engineer created the body of a machine, and the electrical engineer gave them the soul.


Whenever you see some very advanced machines in the factory or on the TV network and marvel at its near-perfect technological level, do you know the sweat that the R&D staff is doing behind, a series of complicated actions that electrical engineers need to write How many lines of code, how many ladders to draw, most of the time, maybe you are already asleep, they often squat on the table, tap the keyboard, hand squatting one after another, sometimes perfect for a movement or It saves 0.1 second for just one action of the machine.
So what do they do specifically?


Take the electrical engineers of most automation equipment companies!


First, after a machine is scheduled to place an order, it is necessary to repeatedly discuss with the mechanical engineer the specific work flow and production process requirements of the machine;


Then, when the mechanical engineer draws the part drawing, the electrical schematic diagram needs to be designed (the circuit diagram at this time is often only preliminary, and the subsequent changes are perfect);


Then, according to the electrical components required on the circuit diagram, the electrical component list of the machine is developed (this list must also be handed over to the purchasing department in a short period of time, otherwise some components may not be purchased back on time due to the delivery date. It affects the delivery date, so the accuracy of the list is very important (but there are often many unsatisfactory places. If the mechanical engineer changes the design idea and increases or changes the structure in order to realize the process requirements, the list needs to be changed. Or re-entered);


Draw the circuit diagram and hand it to the electrician wiring. After completing the list to the purchasing department, the electrical engineer can't be idle. At this time, one of the most important links is waiting for them. What is it?
Yes, it’s programming.


There are many ways to program in the industrial automation industry, mainly PC programming (HMI, industrial computer, etc.) and PC programming (PLC, MCU, etc.), let's talk about the most used HMI and PLC on automation equipment!


HMI, also known as touch-based human-machine interface, is a window for the operator to control the machine. It is actually an embedded touch computer. Each button, screen switch, animation, indicator light, data setting, etc. of the operation interface. All need to be designed by electrical engineers.


PLC is also called programmable controller. It is an important industrial control component. It is equivalent to the machine brain. The various motion control of the equipment is done by it. The electrical engineer will make every action of the machine according to the production process requirements of the product. The details are written in the program, and the HMI communication is completed after the compilation. This process often takes a long time.
Finally, the machine parts and circuits are installed, can the electrical engineer be easy?


You are wrong, the hard life that really belongs to the electrical engineer is about to begin!


There are many times, because the parts are not in place or mechanical changes, etc., so that the machine has just been assembled (some even parts have not yet arrived), it is time to ship, what should I do? Of course, it is the top of the electrical engineer. At this time, the work is to help the electrician check the errors in the wiring, the position of the sensor installation, the parameters adjustment of various components such as servo, frequency converter and temperature controller. After finishing these, the debugging program is the program. The real beginning, and still alone, there are always some people running over and repeatedly asking:


"When can I be good?"


"The machines are all installed, just wait for the electricity."


At this time, in addition to the physical pressure, electrical engineers must also bear the mental pressure, and it is impossible for a person to spend the night in the night.
The machine is shipped, can it be easier? No, in order to meet the strict requirements of the customer's process, the general electrical engineer will go to the site after the machine is shipped, until the machine can be stably produced. This situation is quite smooth. If it is not smooth, the machine structure will be changed repeatedly, and the completion time will have to go backwards. The bitterness in the middle is only understood by themselves.
Then, why is there so many people going forward and sinking into such a busy and boring job?


It turned out that although there were a lot of trivialities and disappointments in the work, they were happy most of the time. Most of the positions were young people in their 20s and 30s. They were full of vigor and vitality. Some of them graduated from colleges and colleges, and only graduated from technical schools. Some are made from electricians.


No matter what you did before, almost every electrical engineer has a dream in his heart. I hope that the machine program I designed is the perfect one, which can bring better operation experience and higher production efficiency to customers. When the praise is the sweetest time, this feeling, like the long dry land encountered the rain, the shaded flowers suddenly saw the sun!


The most uncomfortable thing for them is that a machine has been tossed for many days. Finally, it was found that this structure is problematic. The products produced are problematic. Only when they are reinstated, this kind of discomfort is not only the sweat of many days, but also But it is similar to the bursting of a dream.........
