To meet the need of practical applications,a ground interface system based on industrial controlled ISA bus is designed. The working principles of the oxygen activation tool and hardware interface circuit of the ground interface system are elaborated. The design of ground system interface of the neutron oxygen activation water flow logger is focused on. The explana-tion of communication protocol and transceiving of the dates and commands is realized by MCU,and PCM coding is realized by combination of hardware and software. The interface is designed by ISA bus. The design is applied in fast matching of the ground equipment system and different instruments,and has good compatibility and high reliability.
