In the process of the development of rail transit intelligence, the automatic ticket selling
and checking system (AFC system) is the most direct system to interact with passengers, and
the system stores a lot of passenger information and financial information. Therefore, it is particu
larly necessary to choose a better industrial computer that meets the demands of AFC system and
environmental requirements. For the rail industrial computer used in rail transit, there are several key r
equirements to be met: high reliability and stability, powerful computing power, support for a variety of
communication protocols and interfaces to facilitate data exchange and multi-device applications.
