Collection, which are eliminated same phasor and are repeatedly adopted by concentrating pretreatment unit to carry out concentrated collection to analog quantity, switch state
Collected information is concentrated through a channel and is transferred to scheduling side by the cumbersome behavior of collection, and scheduling side is arranged an information and hands over
It changes planes, each control system is directly changed planes by scheduling top-cross and extracts required information.
9. preprocess method in a kind of data set of more measure and control device fusions as claimed in claim 6, which is characterized in that described
The transmission of step 7 information is using the two of transmission mode：It concentrates pretreatment acquisition → subchannel transmits → to dispatch side subsystem directly to adopt
Collection, the concentration pretreatment unit carry out concentrated collection to analog quantity, switch state, eliminate the numerous of same phasor multi collect
Trivial behavior is transmitted collected information by the system classification subchannel of scheduling side.The scheduling each system in side then passes through designated lane
Directly information is acquired.
