Automation PLANT IMPROVEMENTS AND THOUGHTS
Automation, is a very relative concept, in fact, defines the level of safety technology. A Plenti electrical sense to run a machine easier and there is one thing. Yet, the aim is to stop a running system safe. The main purpose of standards for certification and the CE, a “safe position” to provide. Laptop into the hands of the field “otomasyoncu” the reason that employers looking for a part of the criteria, the system is not only based on the adequacy of work.
All systems, the normal posture in general, can be made hardware and software errors can be fulfilled without any problems. But “accidental stoppage” or abnormal, resulting from accidental or due to failure in the postures is always dangerous. This kind of “dead zones” due to the consistency of stances to put a normal stance, the classical methods are not enough. “Spaghetti” or “intuitive approach” call yöntemsizliklerle, Snapshots are created hardware and software overthrow, in fact safe posture.
Classical methods, albeit in algorithms in hardware and software items must not contain an optimist. Certainly all the algorithms must be based on negativity. Agree to release cheaper economy without negativity enhancement algorithm, “employee” should be greater than the hardware. So, safe stop hardware and software, hardware and software must be more to run. This in fact, the system determines the quality of the excess benefit.
Redundant TECHNOLOGY:
Redundancy (redundant system) technology, albeit a very short I would like to talk about: Business konusununda machines; is continuous and seasonal production facilities (asphalt plant and concrete plant), redundancy technology should be used. This technology is classified zones, the basic level is sufficient for Plants. In other words, Equipment, and IO s need not be redundant. Only the PLC’s and PC’s need to be redundant. In this way, plant, Due to failure of the PLC will not stop. If a problem occurs, equipment or IO cards, it is very easy to change. But the classical system, the backed-up warehouse PLC, is inserted instead of work.
Redundancy of the the basic philosophy of a PLC (CPU) working, it tracks other PLC sees a problem and is engaged to work without interruption. In this way, allow seamless operation. This will stop is valid for two PCs, the system data is lost. Açmışken this topic, at least partly in terms of investment cost, redundant system, according to the normal system, I would say that cost more than about 2-3 times more. Two three-fold reason for dememin; brands and regular price differences, PLCs, configuration sub- limit is decreased. For example, normally done by the PLC, Siemens brand, if we go out, even the asphalt plant automation s7/200 lerle otomasyoncular there. However: even if they do make s7/300 series; The list price of 315-2PN/DP CPU, the CPU 315-2DP from 50%, CPU 314 is greater than 350%. This situation also applies to other markadalar. Plentin PLC automation software is used for a low-capacity, This automation is not of good quality. Automation To install the hardware and software, machinery, process and product as well as knowing better, “requirements engineering” to apply the criteria required to be an orphan.
AUTOMATION QUALITY CRITERIA:
Asphalt plant or concrete plant, regardless of brand programmatical sense, these inquiries should be made to obtain high-quality product. This questioning, elevator chain or 316SS material from st52, come on let’s be humble is as important as the 304 steel. No matter what our profession, we are all doing business, “Requirement Engineering “must use the criteria. The doctors have the Hippocratic oath; our “Engineering and” Do not have our household?
I want to sort a few criteria:
- Moisture meter is a device very emotional, very hard to forget history. Concrete plant, sand 0-3 humidity sensor or attach the eyes of the mixer is not enough. They both have to be a humidity sensor. Electromagnetic sensors, even if moisture, it is true. Moisture sensor that shall include the prices range from $ 3000 to $ 250. How many times the $ 250 of $ 3000 is all known. This is the cost difference between them, also applies to hardware as well as software.
- Batch system:
· Scales are automatic or manual tare, let’s say. Adhesions Kantarlarda very capacity will decrease, product quality will deteriorate. So, this system should stick to akıllılıkta understand.
· Mechanics or imbalances that may occur over time, can al-weighbridge load cell in which information from someone that can detect pollution, has to notify the hardware and software? This affects the accuracy of weighing.
· Fronts to detect possible leaks impressive, to warn?
· According to the production capacity of yapacağanız; cold feed system itself, to adjust?
· Plentinizi first before running the “simulation” mode when you receive, and check the entire system, including the possible ayarsızlıkları prepare a report, Does it offer you?
- All parameters Plenti, authorized passwords do you open? Stores the service itself, you do not have a parametric passwords?
- Dryer burner, threatening to form, with the hardware and software to prevent a possible fuel leak?
- According to the type of fuel you use, a few tons of asphalt to tl automation program generated have to inform you?
- Program reporting, appropriate to ERP. Do you receive these reports online for production planning?
- Crane-truck plant, despite the frequency konverterle drive, will stop on way to look astonished?
- Plant screens, although the placing on the frequency konverterle, trying to mesh, sometimes unbalanced? 300T / h in a plant of different capacities (150 – 200-250t / h) while, at the same rate sieve running? Does the elimination of all capacities of the same quality? (Note: When starting the screening in general practice and the more it vibrates while the soft starter is used to harm sieve. Sieves, employment status, weight or weight set according to the angle, can not adapt to changes in capacity. Everyone knows this information but I wanted to repeat. This is the problem of software and hardware It is possible to solve)
- Plentiniz, “predictive maintenance” to inform you that you have the hardware and software?
CONCLUSION:
Of course the main thing is to meet the need. But the “brand” s the difference, this needs at least cut off (stance), high safety, high efficiency and high product quality that everyone is known. Our country is very advanced in all areas of engineering, it is also true for industrial automation. In our country, We, Refik and many other worthy competitor automation companies, we have the competence to do the best automation.
Still her “maintenance worker”, viewed as carrying this honor for many years, As an engineer I know that, “Maintenance and repair” work, is the world’s most difficult profession, “progress” and “derived” is not I, but “progress” i “tare” falling saving, “failure” of the product is recalled, and in fact determining the quality of basic, a dominant institution.
Writing land mizahvari would like to finish. I think it was the year of 2006. I looked for an officer of a construction company. “Electronic bitumen counter arızalıymış” we can not fix and asked. “Electronic card repair” companies who told him to find someone. Apparently all of them had traveled. Automation of asphalt plants built by the company, materials used in a well-known brand in the market. Of course, this brand, they chose to counter bitumen. Garibime gone. This is a very well-known and quality brand that is really, I know there were good quality water meters, but was sure that bitumen is not counter. Water meters are really perfect quality. These counts were made according to a maximum of 80 ° C, 160 0 C withstood the bitumen of about 6 months.
Of course, asphalt, bitumen produced in the rate of volumetric meters are used to predict what is due to lack of power. Or, is responsible for the laboratory, the operator, to set the rate of bitumen, bitumen, assuming that the correct calibration of the measuring system, in which material parameters have to play left, I can understand what drew penance. But, our “otomasyoncu” gives this account I do not know where.
