The 14 part Part N: use stitch 41～stitch 64 as the used stitch of storage battery activation signals.
The 6th cable W06 is one minute three cable; Three cables that are divided into are respectively the first sub-road B1, the second sub-road B2 and the 3rd sub-road B3; Weak electric signal is further segmented, and the signal that wherein transmits among the first sub-road B1 comprises the signal that above-mentioned the 4th part Part D, the 7th part Part G, the 8th part Part H, Session 9 Part I and the tenth part Part J stitch carry and transmit; The signal that transmits among the 3rd sub-road B3 is the signal that carries and transmit in second portion Part B and the pairing stitch of third part Part C; Be two kinds of signals of Star Service test computer; Star Service scheduling signals and supervisory control signals, the first sub-road B1, the second sub-road B2 and the 3rd sub-road B3 still need use twisted-pair feeder to disturb to reduce; The second sub-road B2 is used for the measurement of satellite emergency-off and above-mentioned first primary power source; The emergency-off function makes the second sub-road B2 be connected with the emergency protection for power-cut plug through the 13 plug connector XD-04 and realizes; Said emergency protection for power-cut plug is a short circuit plug; Its objective is to make the satellite test network short, thereby reach the function of forcing the satellite outage.
64 signal contacts of the first plug connector XT-1 distribute and should take into full account the electromagnetic compatibility of strong and weak electricity, should be separated from each other between forceful electric power and the weakness, same signal contact should be as far as possible near; Weak electric signal comprises the Part A of first～the tenth part Part J among Fig. 2, and the forceful electric power signal comprises the tenth a part of Part K～the 14 part Part N among Fig. 2.
Should as far as possible putting together of the similar contact of signal type, second portion Part B and third part PartC are Star Service test computer signal, and distance is close, and the lead of these two groups of signals all should adopt the form of twisted-pair feeder to reduce interference; The 4th part Part D, the 5th part Part E and the 6th part Part F are command signal, and distance is close; The 7th part Part G, the 8th part Part H, Session 9 Part I and the tenth part Part J are the analog acquisition signal, and distance is close; The 14 part Part N is a storage battery equalizing charge usefulness, will flow through big electric current during test, these contacts should near and away from weak electric signal.
Because the contact that the forceful electric power signal is corresponding will flow through high-power electric current; So the forceful electric power signal should use thicker capillary among the first plug connector XT-1 as far as possible, like the Part A of first among Fig. 2, the tenth a part of Part K, the 12 part Part L and the pairing stitch of the 13 part Part M.
In order further to reduce electromagnetic interference, whole power supply signal the tenth a part of Part K, the 12 part Part L, the 13 part Part M and the 14 part Part N are designed among the 3rd cable W03, with other Design of Signal in the second cable W02.
Technical scheme of the present invention has obtained application on microsatellite of hope of China's emission, and respond well.
The content of not doing to describe in detail in the specification of the present invention belongs to this area professional and technical personnel's known technology.
