After nearly a decade of dedicated collaboration, the R&D team has developed a division of labor based on product categories. However, one role stands out as the "overall manager": testing during the R&D phase. This isn't a standardized process; through years of experience, Zhongcheng Excellence has accumulated rich expertise and established a set of effective and standardized procedures for R&D testing. This involves not only completing testing tasks but also accumulating experience and optimizing the process in the process. Learn more!
Question 1: What is R&D testing?
Zhongcheng Excellence's main product R&D testing specifications include 11 major items and 230 minor items. The major items include single-board level testing, where each circuit on the board must be debugged and verified. There are also type tests, which include many items such as heat, vibration, and EMC, to verify the driver's adaptability to the environment; another aspect is the overall function and performance of the device - the standards that our drivers must meet.
Although it is a test in the research and development stage, the regular standard tests will not be omitted. However, when some special certifications are required and customized test equipment is needed, such as when testing anti-interference ability and external perception ability, or simulating air pressure test in a high-altitude environment, special equipment will be required, and Zhongcheng Excellence will not lower its requirements.
While industry standards exist, they are rather broad. Zhongcheng Excellence, a technology leader, has developed testing standards that are far more stringent than national standards. Especially in the wind power industry, where the operating environment is harsh, R&D personnel must even use their imagination to simulate even more severe conditions to determine product suitability. This process requires a standardized workflow to ensure the results are reasonable.
Question 2: What is the difference between testing during the R&D phase and testing in the final product?
Testing during the R&D phase is completely different from product testing. It is a process of trial and error, and also a process from macro to micro. Through multiple tests, problems are discovered, the source of the problems is found, and finally the problems are solved. This requires a high level of technical ability from the R&D personnel, who need to have a thorough understanding of the entire R&D process.
For new prototypes or newly developed products, R&D personnel prepare several different testing schemes in advance. Problems encountered in each round of testing are first summarized and then tested in the next round. Only after several rounds of improvement can the product performance be perfected. This testing process is actually very tedious, especially when there is no sign of success. Identifying problems is relatively easy; the most difficult part is pinpointing the problem. This requires using various methodologies to investigate step by step, from the source to the pathway, and then to the driver, constantly conducting variable experiments to arrive at a conclusion.
Question 3: What are the qualifications for becoming a qualified R&D engineer in the industrial control system?
First and foremost, attitude is everything. This job requires a rigorous work ethic; the entire testing process must strictly adhere to testing standards, and a single test report is all that's needed to present the work.
Secondly, in addition to a rigorous foundation, one must possess a certain level of logical thinking ability. For example, in the testing process, how to handle problems, how to locate problems, and how to solve them in an organized manner all require meticulous thinking.
Third, of course, one must possess the corresponding professional and technical knowledge; otherwise, one simply cannot understand one's job duties.
Fourth, although it is the last point, it is actually very important: you must have a genuine passion and love for research and development.
Question 4: What is the daily work routine of a research and development engineer like?
In fact, this kind of repeated testing process in the R&D lab is the norm for the R&D personnel at Zhongcheng Excellence. They enjoy it and optimistically believe that there are no problems that R&D personnel cannot overcome; they just need to invest time and effort.
Once, they received a task to conduct product certification within the company, using components from different suppliers. Due to the tight schedule and the urgent task, they worked through the night. If a component exploded, they would remove the driver, replace it with another component, repair the machine, and repeat the same process, working 24 hours a day without rest.
It is precisely because they endure loneliness and accumulate knowledge little by little every day that we can see these ordinary R&D engineers who "have light in their eyes, dreams in their hearts, and a path under their feet."
