People haven't returned home. The air conditioning in the home has automatically adjusted the temperature. The smart meter can help the user to choose a reasonable way to use electricity and reduce the expenses. These are just a small part of the functions of the smart grid.
Smart grids connecting a variety of terminal devices will bring unprecedented functional experience to people. However, its openness and system complexity also mean that smart grids must face the challenges of complex network environments. How to protect the smart grid? A high-tech company in Chengdu gave its own answer: Whether it is the information security problem at the user end or the security issue during the interactive information transmission process, it can be solved only by a single chip.
Little chip
Market value after promotion can have 1 billion yuan
In October this year, Guangdong Power Grid Corporation’s wholly-owned subsidiary, China Electric Power Research Institute, was invited to tender for the entire country. The project is the core of the smart grid system—the research and development project of distribution automation information security protection technology. Among the five bidding companies, Shenzhen Huawei and Wuxi Jiangnan Computer Research Institute have strong strengths, but Chengdu Sanjijia Microelectronics Co., Ltd. finally stood out. Why could this Chengdu company PK drop so many "big names" and take orders? The reporter recently came to Sanjijia Microelectronics and made inquiries.
Speaking of the matter that won the bid last month, the company's general manager, Yen Bin, said in a dull tone: “The company’s R&D personnel are stepping up design and production of chips. The next year will put 30,000 pilots in Guangzhou and Shenzhen. If successful, it will be further implemented in China Southern Power Grid. The market value of promotion and promotion is conservatively estimated at 10 billion yuan.†Analyzing the reason for winning the bid, Ye Bin believes that first of all, his team's security solution not only meets the user's requirements in terms of operating speed, environmental adaptability, and scalability; Secondly, the wealth of experience in the field of power equipment safety with the partner Chengdu Weishitong Information Industry Co., Ltd., and the cost-effectiveness of the bidding project plan are also important weights to win.
How can a tiny chip worth over 1 billion worth? "Can not underestimate this chip, the core secret of the smooth operation of the smart grid in the future is in it." In the face of questions from reporters, Ye Bin played an analogy, "This chip is a bit like the U-shield of online banking, not only It protects the information stored in the user's account, performs user authentication, and records all operations. However, it connects the numerous terminals of the power grid, and the amount of information and calculations contained in it are not comparable to those of the U-Shield."
Isn't the smart grid smart enough? Even with self-healing, why do you need protection? "Compared with traditional grids, smart grids have greater openness and system complexity and can interact with the outside world, but they also mean that there are more opportunities for exposure to 'diseases' and are more vulnerable to external intrusion. Security is multi-factor and multi-dimensional, involving all aspects of system hardware, software, data information, and physical environment, as well as system design, implementation, and operation, and every link cannot be fault-tolerant, especially with smart meters and intelligence. With the popularization of smart phone applications such as mobile phones, there are loopholes in operating systems and smart operating software. All these factors must be considered as much as possible during design. With so many considerations, It takes a year to design the first version of the chip," said Ye Bin.
Core Technology
Let them work with the biggest names in "wrestling the wrist."
The industry experience of Sanji Jiawei Electronics, which was established in 2006, is not long, but it also means that the company is in a rapid growth period of high-tech companies. For them, only mastering core technologies can survive. “The investment in research and development of Sanjijia Microelectronics is not small. Among the company’s 60 employees, 50 are technical engineers, and other administrative personnel are mainly for R&D services,†said Ye Bin.
Having been specializing in information security, GT Microelectronics has gradually grown in the development, testing, sales, and service of related chip products for information security and communications security systems. It has not only built an advanced chip design and development platform, but also has a full-process independent design. Development capabilities.
"Technology companies have the core technology and want to become bigger and stronger. It is very important to choose the road to development." Ye Bin jokingly called the company's choice as "heavy money". His team chose the basis of chip design. As a development direction, the information security chip aims at the procurement chain of banks, electric power, telecommunications, and digital television. "We want to be a real economy in the IT industry, focusing on integrated circuits, focusing on the IC industry, becoming a leader in information security integrated circuits, and creating the future with 'core'!"
“Although we started to make profits in the year we started, but there were only 18 entrepreneurs at that time, and the registered capital was only 4.5 million. After 5 years, the company’s registered capital reached 15 million. Mastering core technologies has given us even more savagery. The three major chips developed by Ye Bin's team: WNG-7 digital physical noise source chip, PCM-CVSD chip, and high-speed modular coprocessor chip have been widely used in digital cordless phones, digital mobile communication devices, and satellite communication networks. , authentication, digital signatures, and other communications and information security products.
"We originally used closed-circuit television to watch TV. Now we need to enjoy a higher-definition picture quality of digital TV. We need to add a set-top box. The original router we used to access the Internet, and now we want to enjoy faster bandwidth, we must add a router with a firewall; In the same way, our original power grid has only basic power supply functions, and the smart grid must have a series of protection devices to provide more functions. The chip is the brain and core of this series of protection devices.†Ye Bin said, “through the distribution In the construction of the network automation system security protection system, the company will apply for 4 national invention patents and 4 utility model patents. In the future, there will be relevant extensions of application equipment to be connected to the smart grid, which must be designed in accordance with our safety requirements.†(Intern reporter Chen Guowen / Figure)
Glossary
Smart grid
With the application of various new technologies such as sensing and measurement technology, information and communication technology, analysis and decision-making technology, automatic control technology, and energy and power technology, a smart grid with strong self-healing, integrated compatibility, and economical optimization functions has left us. The closer you are. In February of this year, the State Grid proposed the "12th Five-Year Plan" smart grid construction target. In the next 5 to 10 years, China's investment in the smart grid will exceed 500 billion yuan. Compared with the existing power grids, smart grids will promote the development of smart communities and smart cities and improve the quality of life of people.
Can make life more convenient - Home smart power system can realize real-time control and remote control of smart home appliances such as air conditioners and water heaters; it can also provide access services for telecommunication networks, Internet, radio and television networks, etc. Electric energy meter to achieve automatic meter reading and automatic transfer fees and other functions.
Can make life more low-carbon - smart grid can access small family wind power and rooftop photovoltaic power generation and other devices, and promote the large-scale application of electric vehicles, thereby increasing the proportion of clean energy consumption and reduce urban pollution.
Can make life more economical - Smart grid can promote the transformation of the role of power users, making it a dual attribute of useful electricity and power sales; Can build a home electricity comprehensive service platform for users, help users to choose a reasonable way to use electricity, saving Use energy to effectively reduce electricity expenses.
