As the first edge computing industry promotion project in China, the “Edge Computing Standard Parts Plan” was jointly initiated by the China Academy of Information and Communications Technology, the Industrial Internet Industry Alliance, the Key Laboratory of Internet and Industry Integration Innovation and the Ministry of Information Technology, aiming to form an industrial closed loop of “technology research and development, standard development, product testing, application demonstration, and large-scale commercial use”. Effectively assist equipment manufacturers to optimize iterative product capabilities, and provide users with reliable and accurate selection references, laying a key foundation for promoting large-scale deployment of edge computing. After nearly 4 years of development, the “Edge Computing Standard Parts Program” has completed centralized testing of four batches of products and provided testing services for more than 60 products.

CI535V26-3BSE022161R1 The 5G virtualization industrial control gateway independently developed by China Mobile Research Institute successfully passed the product test of this “Edge Computing Standard Parts Plan”, and has been deployed in practical applications and continued stable operation in many fields, helping enterprises in various industries to upgrade their applications and promote the landing of digital construction.

Wired technology is widely used in traditional industrial network, which has some problems such as complex hierarchy, difficult deployment and insufficient flexibility. Due to shortcomings in communication delay, anti-interference, stability and other aspects, the existing industrial wireless technology is difficult to meet the strict performance requirements of industrial networks for communication certainty and high reliability. It mainly serves data collection, video return, mobile inspection and other services, and is difficult to penetrate into the core production link of industrial control. On the other hand, the industrial control architecture represented by the traditional PLC (programmable logic controller) is closed, and the vertical chimney structure leads to poor scalability, difficult integration and high cost, and the control architecture of “computing power does not go down and data does not come” is difficult to meet the development needs of the industrial Internet.

5G virtualization industrial control gateway

In response to the challenges faced by industrial wireless and open automation, China Mobile has created 5G virtual industrial control gateway products, aiming to create technological innovation, excellent performance, independent and controllable 5G+ industrial end-to-end high-quality control and assurance technology, and taking 5G industrial gateway as the anchor point, innovating the three key technologies of certainty, new short range and virtualization PLC. Solve the problems of communication quality assurance, heterogeneous protocol access and industrial control business development in interference environment.

5G+TAN Determinism enables deterministic transmission of the controller northbound

For the high deterministic needs of the industry, 5G+TAN (time-clear network) technology provides bounded delay jitter, high reliability, high-precision clock synchronization and other capabilities through endogenous dual transmission selection, multi-link redundant transmission, delay threshold control, cross-clock domain collaboration and other technologies to achieve end-to-end deterministic transmission. In the 5G (R16) environment, the timing accuracy error of southbound 1588v2 is less than 500ns, and the software-defined delay error is less than 10 microseconds. In the interference environment, the packet loss rate is reduced by more than 40%, and the delay is reduced by more than 20%. At present, 5G deterministic industrial gateway and supporting deterministic controller have been developed to achieve double 5G transmission, and the base station has no perception switching, ensuring the stable and smooth operation of various services.
