Abstract: In view of problem of bad reusability of special gateway of mine access gateway, a design scheme of mine integrated access gateway based on S5PV210 was proposed. Hardware structure and software design of the access gateway were introduced, conversion principle among various protocols was analyzed in details. The gateway adopts S5PV210 microprocessor, embedded operating system and Socket software technology to realize interconnection among wireless network, field bus network, control device and industrial Ethernet and multi-protocol conversion.
