Recently, technicians from Chongqing University of Posts and Telecommunications' Industrial Internet of Things and Networked Control Key Laboratory of the Ministry of Education showed the Chongqing "Core" No. 1 chip.
The length and width are only 6 mm, and the degree of integration is very high. It can be widely used in the fields of smart industry, smart grid, smart transportation, etc ... The reporter learned on March 25 that it was jointly developed by Chongqing University of Posts and Telecommunications and Taiwan Dasheng Electronics Co., Ltd. The world's first IoT core chip supporting the three major industrial wireless international standards-Chongqing "Core" No. 1, will be mass-produced and applied within this year.
Received much attention after its debut last year
The Industrial Internet of Things effectively reduces the cost of automation and increases the scope of application of automation systems by supporting the interaction and interconnection between devices. It plays an important role in promoting the level of manufacturing informatization, promoting the integration of industrialization and informatization, and optimizing and upgrading the industrial structure. Among them, the wireless network is the key technology of the Industrial Internet of Things, which has extremely high requirements on response time, anti-interference and reliability, but ordinary civilian chips cannot meet this demand.
Chongqing Yuxin No. 1 developed by Chongyou and Dasheng Electronics can support the three mainstream industrial wireless international standards, such as ISA100.11a, WirelessHART and WIA-PA, which have been formed by the global industrial Internet of Things. Because it uses an advanced radio frequency architecture, it has the advantages of low power consumption, low cost, miniaturization, and high reliability. Since its appearance at the 2012 China (Chongqing) International Cloud Computing Expo last year, it has attracted much attention.
Replacing some software functions, processing speed increased by 50%
"The biggest feature of this chip is that in the case of industrial wireless networks, many functions that were implemented by software in the past are directly supported by hardware." Dean of the School of Automation, Chongqing University of Posts and Telecommunications, Ministry of Education, Industrial Internet of Things and Networked Control Wang Ping, director of the key laboratory, introduced. Nowadays, in many automated production lines, most enterprises adopt the method of industrial wired network, but the cost of wiring is very high, accounting for more than 60% of the installation and maintenance cost of the entire automation system. Many companies hope to use industrial wireless networks instead.
"Software support consumes a lot of resources, affects the processing speed of the CPU itself and the storage resource space, and it will also cause the processing speed and accuracy of the application system to decrease, and delays and insufficient reliability may occur." Wang Ping said that under the conditions of the same function, using the chip to achieve functional support can increase the processing speed of the software by about 50%, other system parameters will increase accordingly, and resource consumption can be reduced by about half.
Expected selling price is only RMB 20-30 per piece
According to reports, there is no similar technical achievements at home and abroad. The successful research and development of Chongqing "Core" No. 1 also marks that China has reached the world's leading level in the field of industrial Internet of Things technology.
Wang Ping revealed that Yuxinxin No.1 will be continuously improved in terms of reliability and stability, and mass production and application can be achieved within the year. The estimated selling price is about 20-30 yuan per block, which has huge market potential and commercial value. .
