Wang Cheng studied physics in college and had little to do with computers. From the beginning of simulation, I gradually entered the computer field, and since then I have formed an indissoluble bond with it.
China's missile industry got a lot of help from the Soviet Union in its initial stage, but the Soviet Union always left a hand in key technologies. At the beginning of missile development, the developers realized that the simulation center for simulating and verifying the missile control system must be built as soon as possible, and reported the specific plan of building the center to the superior. Soon, he was explicitly instructed to "rely mainly on self-reliance and strive for foreign aid as a supplement", and immediately began to mobilize and train the research team to build the China missile system simulation station. At the same time, he also urgently started the negotiation of introducing "electronic card simulation station" from the Soviet Union. After several rounds of negotiations, the Soviet Union agreed in principle to sell the system to China, but deleted some key components in the system, especially the "main console" and the "optimizer" that can automatically seek the best parameters of the control system. Knowing that the other party intends to set up a card, but in order to get started as soon as possible, I decided to introduce the "electronic card simulation station" and at the same time issued the task of developing the "main console" and "automatic optimizer" by myself. As the deputy stationmaster of the "simulation station", Wang is responsible for the simulation of his own missile system and participated in the development of these two key equipment, which is Wang's first step into the computer industry. Because of the tight time, heavy task and weak foundation at that time, he almost started from scratch. With a strong sense of responsibility and mission, he worked with all the developers to tackle key problems and fight day and night, and finally successfully completed the task. Subsequently, Wang Cheng condensed some mechanisms and methods in the automatic optimizer into a paper that can be published, and published it in acta automatica sinica in 1966+65438.
With the urgent demand for simulation in various industries in China, if we continue to introduce computers from abroad, it will not only hinder negotiations frequently, but also be expensive and spare parts cannot be guaranteed. At that time, it became a very urgent task to develop and produce various simulation computers by ourselves. Wang Cheng once participated in the development of M2, M3, M4, M5 and M6 series analog computer systems, and successfully completed the promotion to production conversion plants and application units. At the same time, he also participated in the development of ground control computers for some missiles and special computers for missile guidance system, which contributed to the development of China's missile industry.
Since 1970s, software has become the key of computer system, and China urgently needs to train and bring up a team of software developers. When his superiors mobilized Wang to turn from system structure and hardware design to "software development", he immediately devoted himself to the development of S-8 digital computer operating system. 1July, 985, the operating system passed the national technical appraisal successfully, and Wang Cheng also won the second prize of the National Science and Technology Progress Award and the first prize.
