The world's first IoT core chip that supports international industrial wireless standards

Recently, technicians from the Key Laboratory of Industrial Internet of Things and Networked Control of the Ministry of Education at Chongqing University of Posts and Telecommunications demonstrated the Chongqing "Core" No. 1 chip to everyone.

　　It is only 6 mm in length and width, with a high degree of integration, and can be widely used in smart industry, smart grid, smart transportation and other fields...The reporter learned on March 25 that the world's first Internet of Things core chip that supports the three major industrial wireless international standards, Chongqing "Core" No. 1, jointly developed by Chongqing University of Posts and Telecommunications and Taiwan's Dasheng Electronics Co., Ltd., will be mass-produced and applied this year.

　　After its debut last year, it attracted much attention

　　The Industrial Internet of Things supports the interaction and interconnection between devices, effectively reduces automation costs, and expands the scope of application of automation systems. It plays an important role in improving the level of informatization in the manufacturing industry, promoting the integration of industrialization and informatization, and promoting the optimization and upgrading of industrial structure. Among them, wireless networks are the key technologies of the Industrial Internet of Things, which have extremely high requirements for response time, anti-interference and reliability, but ordinary civilian chips cannot meet this demand.

　　Chongqing University of Posts and Telecommunications and Dasheng Electronics developed the Chongqing Core No. 1, which can support the three major international industrial wireless standards that have been formed in the global industrial Internet of Things, including ISA100.11a, WirelessHART, and WIA-PA. Since it uses advanced radio frequency architecture, has the advantages of low power consumption, low cost, miniaturization, and high reliability, it has attracted much attention since its debut at the 2012 China (Chongqing) International Cloud Computing Expo last year.

　　Replace some software functions and increase processing speed by 50%

　　"The biggest feature of this chip is that in the case of industrial wireless networks, many functions that were previously implemented by software can now be directly supported by hardware," said Wang Ping, dean of the School of Automation at Chongqing University of Posts and Telecommunications and director of the Ministry of Education Key Laboratory of Industrial Internet of Things and Networked Control. Nowadays, most companies use industrial wired networks in many automated production lines, but the wiring cost is very high, accounting for more than 60% of the installation and maintenance cost of the entire automation system. Many companies hope to replace this with industrial wireless networks.

　　"Software support consumes a lot of resources, affecting the CPU's processing speed and storage resource space. It will also cause the application system's processing speed and accuracy to drop, and may also cause delays and insufficient reliability." Wang Ping said that under the same functional conditions, using chips to implement functional support can increase the processing speed of software by about 50%, and other system parameters will also increase accordingly, while resource consumption can be reduced by about half.

　　The estimated selling price is only 20 to 30 yuan per piece

　　It is reported that there are currently no similar technological achievements at home and abroad. The successful development of Chongqing "Core" No. 1 also marks that my country has reached the world's leading level in the field of industrial Internet of Things technology.

　　Wang Ping revealed that Chongqing "Core" No. 1 will continue to improve in terms of reliability and stability, and will be able to be mass-produced and applied within the year. The estimated selling price is around 20-30 yuan per piece, and it has huge market potential and commercial value.
