On the afternoon of August 17, 2018, the "Embedded Internet of Things Forum Salon" hosted by Shandong Electronics in Shenzhen and sponsored by Luguang Electronics was grandly held at the reception hall on the third floor of Yonghe Brothers Automobile Company in Nanshan Zhihe Industrial Park, Shenzhen.
Mr. Zhu Ligui, founder of Shandong Electronics in Shenzhen and chairman of Shenzhen Luguang Electronic Technology Co., Ltd., delivered a wonderful speech before the meeting. In line with the guiding ideology of Shandong Electronics' 12 word business policy of "integration, teamwork, and win-win cooperation", President Zhu, in combination with the current tense international situation, "China Dream, China Core" is certainly a science and technology topic that the party and state leaders attach great importance to. "Science and technology is the first productive force". After the "ZTE event", I believe that every Chinese will be determined to work hard to accelerate the development of science and technology in all fields and the rise of "core" closely around the "the Belt and Road" national policy! In the new era, we need to explore the development of new and renewable energy sources while ensuring the supply of traditional energy. With the continuous rise of China's new energy, new technology, intelligent industry, automotive electronics and other industries, every technological field is closely focused on the lifeline of science and technology, united, technologically innovative, responsive to national policies, never forgetting our original intention, and forging ahead!
At present, the localization and self-sufficiency of China's semiconductor industry is undoubtedly a new trend and new trend of future development. As a benchmark enterprise in the semiconductor industry, Luguang Electronics will also follow the "the Belt and Road" advocated by the country, actively respond to national policies, boldly lead small and medium-sized enterprises in Shandong Electronics, and actively hold this epoch-making salon activity. At the same time, it will be hosted by senior experts engaged in the semiconductor electronics industry for nearly 30 years, Yinninghua instructors who have worked in visits to several Silicon Valley semiconductor companies and Stanford University, MBA of Beijing Jiaotong University, and judges of various Maker Contests. The salon atmosphere of the whole forum is: "focus together, talk about cooperation, and plan for win-win", and everyone will actively discuss and exchange The PPT presentation of each enterprise is very detailed.
The prominent companies with distinct themes in this forum salon include Huada Semiconductor, Haier, and Hisense's Shenzhen office. Prominent representatives of on-site enterprise PPT release and interactive communication include: Huang Hui, Technical Director of Luguang Electronics Group; Lin Jinhai, Director of Jieyang Xunke Electronics; Zheyang Technology Xu Haijun Project Chief Engineer; Wang Yulin, General Manager of Hantaiwei Electronics; Ouyang Erjian, Engineering Director of Nanjing Nat Communication Electronics; Director Zheng Minghui of Rongchuang Xincheng and others have made the learning interaction and resource sharing atmosphere at the venue more lively.
After a 5-hour forum, the Embedded IoT Forum Salon finally came to a successful conclusion, and everyone happily left behind a group photo. Finally, under the call of Chairman Zhu of Shandong Electric in Shenzhen, a lavish thank-you dinner was arranged at the restaurant of Nanshan Zhihe Industrial Park with full sponsorship from Luguang Electronics!
This salon meeting has come to a temporary end, and more exciting events need to continue in the future.
For this embedded IoT forum salon event, the essential topic content is compiled as follows:
