| Abstract: | MOXA UC-7101 is utilized as hardware.System communication follows modbus protocols.Under uclinux Embedded OS,application software is programmed.By this program,when net is connected datum between monitor center and weapon terminator can be transferred correctly and timely.While net is shut off,MOXA begins to poll weapon terminator and response datum is stored into SD card in MOXA.System testing Results are also demonstrated in detail. |
