Industrial Switch Helps the Development of Rail Transit AFC Industry

On March 15-16, 2023, nearly 1000 representatives from national subway construction and operation, major design institutes, integrators, equipment manufacturers, and related supporting enterprises gathered together for exchange and discussion on the theme of "Discussion on the Development Road of AFC Industry". In the big river of rail transit, AFC conferences are like surging waves, leading people to perceive trends and see the future!

In his opening speech, Du Qian, chairman of the AFC Special Committee of the China Information Industry Chamber of Commerce, pointed out that we are in the midst of a major change that has not occurred in a century. The modernization process with Chinese characteristics will be accelerated, and expanding domestic demand will become an inevitable choice. He emphasized that with policy support and a tolerant attitude, enterprises can freely do things and use our core technology to jointly create and welcome the arrival of a new era of industrial development. Guests and dignitaries conducted in-depth discussions on topics such as "green intelligence integration", "localization", and "innovation", sharing insights, guiding us in the direction and strengthening our confidence. Many enterprises also bring new technologies and products to share with representatives. Houshi Network Technology's independently controllable Industrial Switches and other communication equipment, as well as professional communication solutions for rail transit AFC systems, have attracted many guests to "watch".

Metro AFC (Automatic Fare Collection System) is an automated ticketing and checking system based on computer technology, information collection and processing technology, and mechanical manufacturing, with high intelligent functions. The goal of AFC is to automate the entire process of subway ticket sales, ticket checking, billing, charging, statistics, sorting, and management. For subway operating companies, it has improved the operational efficiency and revenue of the subway system. AFC system is one of the most basic and important systems in subway operation, so the stability requirements for AFC network communication system are very high.

Professional Communication Solution for AFC System of Houshi Industrial Switch

Install the IS2000 series industrial switch at the front end ticket selling and checking equipment, connect each ticket selling and checking equipment using a 100 megabyte electrical port, install a gigabit SFP optical fiber module on the optical fiber interface of the IS2000 and IS3000 industrial switches, and establish an ERPS self-healing ring network to ensure that the link failover time can be restored within 20 ms, providing high reliability assurance for AFC data transmission.

In the AFC sorting center, we recommend to use IS5000 series industrial switches, adopt full gigabit optical fiber modular interfaces, and gather AFC optical fiber links from various sites to ensure that the backbone link between the sorting center and each site is a full gigabit optical fiber backbone network, so as to build a high-speed data transmission network with high bandwidth, high stability, and high reliability for AFC.

The communication equipment of our industrial switch in the entire AFC network system all support centralized control and management through various methods such as SNMP, WEB browser, CLI command line, SSH, and Telnet, facilitating maintenance personnel to perform remote login, port mirroring, remote monitoring, status monitoring, and other operations.

Only by adhering can breakthroughs be made. In the past 10 years, Houshi Network Technology has focused on industrial switches, never forgetting its original intention, making independent innovation, and advancing with the times to promote localization, contributing to the construction of China's transportation power. Today, our industrial switch products are widely used in rail transit systems such as signaling, communication, and AFC for nearly 100 subway lines in more than 20 cities across the country.

The AFC Hangzhou Conference has provided us with a good communication platform and is more like a "strong shot", allowing us to confidently move forward on a determined path. The meeting called on everyone to form a consensus and work together to regain the courage to forge ahead under the construction goal of integrating urban rail transit, green intelligence, and accelerate innovation in technology, especially in industrial switch products. Breakthroughs should be pursued in application, so that the development of rail transit AFC can be reborn and accelerated, and the cause of rail transit AFC can be expanded, strengthened, and new.
