8. the full station intelligent terminal analogue means using method of a kind of intelligent substation according to claim 7, is characterized in that, when described in described step 5), data processing module carries out logical process, is undertaken by following logic:
A), the intelligent terminal analogue means of entirely standing is setting up step 1) to step 4) and after starting working, the position of the switch initial value arranging to step 3) according to step 1) is by step 1.5) in the optical Ethernet interface that arranges GOOSE message that the full station of simulation intelligent terminal is sent to each auto correlation be sent in application apparatus, it is initial value that the position of the switch is worth;
B), entirely stand intelligent terminal analogue means while receiving the displacement GOOSE message of switchgear, data processing module mates with SCD file the GOOSE message receiving according to APPID, MAC Address, determine the associated intelligent terminal of switchgear that needs displacement, further determine according to the mapping of the empty terminal of the circuit breaker trip signal arranging in step 4), the empty terminal of switching signal, the empty terminal of switchgear remote signal, the empty terminal of switchgear operation block signal the positional value that switchgear is new; By GOOSE message format and mechanism by step 1.5) in the optical Ethernet interface that arranges the simulation GOOSE message that intelligent terminal sends each auto correlation of entirely standing is sent in application apparatus;
C), entirely stand intelligent terminal analogue means when having man-machine interaction instruction to need switchgear displacement and not receiving switchgear displacement GOOSE message, according to the switchgear positional value of man-machine interaction instruction and associated intelligent terminal, by GOOSE message format and mechanism from by step 1.5) the optical Ethernet interface that arranges the simulation GOOSE message that intelligent terminal sends each auto correlation of entirely standing is sent in application apparatus;
D), entirely stand intelligent terminal analogue means unmanned plane interactive instruction change switchgear position, full station and while not receiving switchgear displacement GOOSE message, full station intelligent terminal analogue means is by step 1.5) in the optical Ethernet interface that arranges the simulation GOOSE message that intelligent terminal sends each auto correlation of entirely standing is sent in application apparatus, position of the switch value remains unchanged.
