Abstract
The invention belongs to Aerospace vehicle test equipment, more particularly to a kind of method to Aerospace vehicle test signal branch process.The present invention by Aerospace vehicle test signal branch process, design, solve in traditional test mode by the cut-out of aircraft original measurement and control signal transmission channel, operation difficulty is larger, testability design level is relatively low the drawbacks of.The method of new Aerospace vehicle test signal branch process, design implementation is simple, and on-the-spot test is easy to operate, has been obviously improved the testability design level of aircraft.
Description
Technical field
The invention belongs to Aerospace vehicle test equipment, more particularly to a kind of method to Aerospace vehicle test signal branch process.
Background technology
, typically will first clear and definite test event and method, corresponding in Flight Vehicle Design when carrying out ground test to aircraft
Test interface, and develop supporting interface channel for test interface, the various digital quantities of TT＆C system on aircraft believed
Number, analog signalses introduce test equipment be monitored, judge.In the process, often by the original signal of TT＆C system
Transmission channel is cut off and measured signal is introduced into test equipment detection, processing at this.Such design method is to a certain extent
It has impact on aircraft and carry out total system state verification, increase the operation difficulty at scene, make the testability design level of aircraft
Reduce.
The content of the invention
The object of the invention：
In order to solve TT＆C system during Aerospace vehicle test, ground checkout equipment can not receive simultaneously, monitor aircraft
The problem of various types of signal, is, it is necessary to design a kind of new method for receiving, handling to Spacecraft TT＆C signal branch, realization flight
Device carries out ground test under total system connection status, reduces on-the-spot test operation difficulty, improves aircraft fault detect rate.
Inventive technique scheme：
A kind of method to Aerospace vehicle test signal branch process, it is characterised in that by the original measurement and control signal of aircraft
All signals carry out branch process, communication interface designing impedance matching in transmission channel；A set of signal branch is manufactured to receive, transmit
Cable, signal will be passed under aircraft and is divided into two-way, therefrom converting interface is sent into ground checkout equipment all the way, sends observing and controlling system back to all the way
System.
The signal branch receives, transmission cable include test equipment to the one-to-one signal straight-through cable of middle converting interface and
The three interface cables that port is divided into two.
Described straight-through cable one end is connected with signaling interface on ground checkout equipment, and the other end is connected to middle converting interface.
Transit cable one end is connected to middle converting interface, and both ends connect tested aircraft end signal outlet and are tested respectively in addition
Aircraft end signal entrance.
Plug, the socket of the middle converting interface connection select according to measured signal characteristic.
The beneficial effect of invention：
Aerospace vehicle test signal branch process, design are carried out according to such scheme, solving will in traditional test mode
The drawbacks of original measurement and control signal transmission channel of aircraft is cut off, operation difficulty is larger, testability design level is relatively low.New flies
The method of row device test signal branch process, design implementation is simple, and on-the-spot test is easy to operate, has been obviously improved aircraft
Testability design level.
Brief description of the drawings
Fig. 1 test cable external structure design diagrams
Fig. 2 signal branch process design principle figures
Wherein：Converting interface, the interface cables of 4- tri-, 5- fly in 1- test equipment end signals interface, 2- straight-through cables, 3-
The outlet of row device end signal, 6- aircraft end signals entrance, 7- are tested aircraft, 8- test equipments
Embodiment
The present invention is further described below in conjunction with the accompanying drawings：
As shown in Figure 1 and Figure 2, the present invention has carried out all signals in the original measurement and control signal transmission channel of aircraft point
Road is handled, communication interface designing impedance matching；A set of signal branch reception, transmission cable are manufactured, signal point will be passed under aircraft
For two-way, therefrom converting interface is sent into ground checkout equipment all the way, sends TT＆C system back to all the way, ensure that aircraft connects in total system
The state of connecing is tested, and has been obviously improved the testability design level of aircraft.
The signal branch receives, transmission cable, comprising：One-to-one signal straight-through cable of the test equipment to middle converting interface
2 and three interface cables 4 that port is divided into two, the one end of straight-through cable 2 be connected to test equipment end signal interface 1, separately
One end is connected to middle converting interface 3, and the one end of cable 4 is connected to middle converting interface 3, and both ends connect the outlet of aircraft end signal respectively in addition
5 and aircraft end signal entrance 6.
According to aircraft end signal outlet 5 and the connector model of aircraft end signal entrance 6, selection corresponds, phase
Army's grade rectangular electric connector of matching；According to the socket model of test equipment end signal interface 1, corresponding circular aviation is selected to insert
Head；The plug of converting interface 3, socket in being selected according to measured signal characteristic.
After the completion of plug, socket type selecting, according to the particular content of Aerospace vehicle test signal, quantity, electrical characteristic, closed
Manage the processing such as arrangement, impedance matching, anti-interference；Using aviation silver-plated copper core insulation wire, processing, cable is made, made
Insulated after, checking.
During Aerospace vehicle test, the one-to-one interface cable 4 of signal straight-through cable 2 and three is connected by middle converting interface 3,
And the test equipment end signal interface 1 in test equipment 8 is respectively connecting to, and the aircraft end signal on tested aircraft 7 goes out
Mouth 5 and aircraft end signal entrance 6, you can carry out product test.
By taking sign1 as an example, signal trend is during test：5s are exported from aircraft end signal, are flowed directly into all the way winged
Row device end signal entrance 6, converting interface 3 flows into test equipment end signal interface 1 during another way passes through.
