On November 27, 2017, the State Council issued the "Guideline for the State Council on Deepening the "Internet + Advanced Manufacturing Industry" to Develop the Industrial Internet," and proposed the organization and implementation of the upgrade of the industrial Internet industrial enterprise intranet, the industrial enterprise extranet, and the logo analysis system. By 2020, it will initially establish a low-latency, highly reliable, widely-covered industrial Internet network infrastructure.
The comments clearly stated that industrial enterprises were supported to use industrial IPv6 and passive optical network (PON) technologies to implement industrial enterprise intranet transformation and accelerate the application of industrial Internet in industrial sites.
What is Industrial PON
Industrial PON is an all-optical PON network system used in industrial environments. It is an access network that adopts optical fiber transmission technology. It generally refers to a system in which an optical fiber is used as a transmission medium between an end office or a remote module and a user.
The industrial PON consists of an OLT (Optical Line Terminal) installed at the central control station, an ONU (Optical Network Unit) installed at the customer premises, and an ODN (OLT) between the OLT and the ONU (Optical Distribution Network, including optical fiber and passive Splitter or coupler).
PON (passive optical network) means that ODN (optical distribution network) does not contain any electronic devices and electronic power supplies. ODNs are all made up of passive components such as optical splitters and do not require expensive active electronic devices.
What can an industrial PON do?
The industrial PON system can meet various application scenarios such as enterprise production control, process and process data collection, monitoring, and video surveillance. Industrial network platform based on PON technology integrates product design R&D, manufacturing, production, sales, logistics, and after-sales industrialization. It finally realizes the unified control and management of system information islands such as CRM, MES, ERP, SCM, and SCADA.
It is precisely because of the core position of industrial PONs in the industrial Internet that the state is encouraged to encourage enterprises to develop and use industrial PONs from the policy level.
expert's point
Dr. Fan Ji'an, a National Thousand Talents Program expert and chief scientist of China Unicom Big Data, said that compared to traditional Ethernet, industrial PONs have long connection distances, strong anti-jamming and anti-pollution properties, and high performance and security features, making them in-house. The solution has stronger capabilities and is an essential infrastructure for intelligent workshops, smart factories, and smart parks.
In the past, what carriers did was extranet. The intranet was all designed and deployed by the enterprise. Now, the operator's industrial Internet has begun to enter the park or even enter the workshop. Now Unicom is mainly providing industrial PON solutions for industrial parks and enterprises aiming at the upgrading of new parks, factories and original plants.
The industrial PON solution boasts all-optical and flat network features, and surpasses existing Ethernet technologies in terms of security availability, network performance, and service access capabilities, and has become the preferred solution for industrial-grade network connectivity.
The program is used in data acquisition, monitoring, production control and other scenarios in the manufacturing field to realize integrated management of manufacturing companies, machines, materials, rings, and processes, complete production equipment, logistics warehousing, accessories, tools, and workshop-level and factory-level operations. The information system is organically connected to form an intelligent manufacturing information network system, and an automated, informatization, digital, and intelligent industrial Internet basic network is built for manufacturing companies.
A TPU Screen Protector made of the super toughness of the honeycomb structure. Its unique ultra-soft properties allow it to cover the most complex curves and contours in a device.
The self-healing design of the Hydrogel Screen Protector can protect the display screen of the device from damage, leave no air bubbles, and maintain the sensitivity of the touch screen.
