S1, the electrical interface to each unit and test equipment in satellite GNC semi-physical systems, enter according to signal type
Row classification, the electrical interface to same signal type, using identical connector, as shown in Figure 1.
Classification is carried out to electrical interface by signal type to include：Electrical interface is divided into into power supply interface, communication interface and analog quantity
Collection (remote measurement and ground are surveyed) interface.Wherein, power supply interface includes 5V (volt) power supply interfaces and 28V power supply interfaces again.GNC semi physicals
The cable system of analogue system is to weight no requirement (NR), it is considered to which cost adopts standing connector, cheap, reliable and stable, user
Just J14A-9 connectors, J36A-9 plug-in units, DB9 plug-in units, DB62 plug-in units etc..In the present embodiment, 5V power supply interfaces are adopted
J14A-9 connectors, as shown in figs. 2 a and 2b；28V power supply interfaces adopt J36A-9 connectors, as shown in figures 3 a and 3b；Communication connects
Mouth adopts DB9 connectors, as shown in fig. 4 a and 4b；Analog acquisition interface adopts DB62 connectors, as shown in Fig. 5 A and 5B.Adopt
It is less with 5V units of powering, therefore J14A-9 connectors quantity is few, whole cable system is mainly using conventional J36A-9 connectors
With DB9 connectors, to offering convenience during use.
S2, the contact to connector are defined, and the length of the cable that connector is connected is fabricated to preset length, complete
The design of paired cable net.
In the present embodiment, cable length is produced in batches according to 4m.To each signal type using patching for selecting
Part, unified definition contact.Power supply (electric current is larger, belongs to forceful electric power) is separately designed with signal (electric current is little, belongs to weakness), and is connect
Point definition unification, from connector model distinguishing signal content, to prevent connector model wrong plug.For communication cable, cable connects
Point definition is consistent, and itself has interchangeability, even if there is connector displacement wrong, is also unlikely to bring unit substantive shadow
Ring, it is ensured that the safety of whole satellite GNC semi-physical systems unit product in test process.
As shown in Figure 2 A, 5V power the 1 of the J14A-9TK connectors of unit, 2 points be 5V+, 8,9 points of ground connection (GND)；As schemed

The needs of the test site of analogue system are configured.Some 5V of making power, 28V powers, serial communication, analog acquisition
Four kinds of specifications extend cable and especially run into change test site, as shown in Fig. 6 A～6D, product is placed on special installation, is caused
Need cable extension, now can immediately according to be actually needed access extend cable configurations into suitable cable.
In the present embodiment, it is preferred that also comprising one design transit cable the step of, if satellite GNC semi-physical simulations system
Have in system and newly grind unit, then according to the electrical interface for newly grinding unit, design transit cable.
Generally, the unit product used by satellite GNC semi-physical systems, can select ripe single when inheritance is considered
Machine, whole satellite GNC semi-physical systems, more and more employing type spectrum products, as long as type spectrum product is adopted, as electricity connects
Mouth does not have any change, can continue to use type spectrum product end cable always.As long as and signal type is consistent, it is possible to access whole
Cable system, ensure that the reusing of cable system to the full extent.Due to cable standard, it is not necessary to which redesign is entirely defended
Star GNC system semi-physical simulation cable systems.If having in satellite GNC semi-physical systems newly grind unit, basis newly grinds unit
Electrical interface, design transit cable, and design newly ground the transit cable of unit and is designed for uniformity according to generic definition interface, than
Design whole cable system much more convenient.
In satellite GNC semi-physical system test processs, due to test, troubleshooting, unit etc. is changed, flexibly can be entered
Row is exchanged, contrast test, brings very big convenience to system test.
Although present disclosure has been made to be discussed in detail by above preferred embodiment, but it should be appreciated that above-mentioned
Description is not considered as limitation of the present invention.After those skilled in the art have read the above, for the present invention's
Various modifications and substitutions all will be apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
