The emulation for controlling system simulation platform discrete output signal improves.
Background technique
The present invention derives from the testing requirement of flight control system.When testing flight-control computer, observing and controlling system
System needs to emulate the discrete magnitude signal of external sensor output.Including: ground/open, 27V/, 15V/, 27V/ open,
15V/ is opened.
When the discrete signal that traditional TT&C system exports external sensor is acquired, due to discrete signal type and
Characteristic is different, needs for various types of signal behavior difference discrete magnitude output board cards.This mode increases test macro
Complexity and cost.
Summary of the invention
The technical problems to be solved by the present invention are: proposing a kind of TT&C system discrete output signal conditioning module, will survey
The standard 5V Transistor-Transistor Logic level that board exports in control system is converted to different types of discrete output signal.To meet control system of flying
Discrete magnitude signal emulates demand when unified test tries, and acquires for flight-control computer.
TT&C system discrete output signal conditioning module of the invention, the standard 5V TTL electricity for exporting TT&C system
Heibei provincial opera reason is that flight control computer required analog signal, conditioning module input terminal in test are connect by resistance R1 all the way
Ground, another way are connect by NOT gate U1 with the end coil a of relay U2, and the end coil b of relay U2 and external power supply Vcc connect
It connects, common end COM is connect as output port, normal-closed end NC with the second stitch of wire jumper mouth U3, normally open end NO and wire jumper mouth U4

The beneficial effects of the present invention are: by this conditioning module, can be greatly decreased testing system board card type class, reduce at
This.
Detailed description of the invention
Fig. 1 is circuit diagram of the invention.
Specific embodiment
The present invention is described in further details below.Referring to Fig. 1,
A kind of TT&C system discrete output signal conditioning module, the standard 5V TTL level for exporting TT&C system
Conditioning is that flight control computer required analog signal, conditioning module input terminal in test are connect by resistance R1 all the way
Ground, another way are connect by NOT gate U1 with the end coil a of relay U2, the end coil b of relay U2 and external power supply Vcc
Connection, common end COM are connect as output port, normal-closed end NC with the second stitch of wire jumper mouth U3, normally open end NO and wire jumper mouth
The first stitch of U4 connects, the second stitch ground connection of wire jumper mouth U4；The first stitch and third stitch point of the wire jumper mouth U3
It is not connect with voltage transformation module U5 and voltage transformation module U6.
When desired signal is "/open ", the first stitch and the second stitch of tie jumper mouth U4；When desired signal is
" V1/ " when, the first stitch and the second stitch of tie jumper mouth U4, the first stitch and the second stitch of tie jumper mouth U3；
When desired signal is " V2/ ", the first stitch and the second stitch of tie jumper mouth U4, the second stitch of tie jumper mouth U3
With third stitch；When desired signal is " V1/ is opened ", the first stitch and the second stitch of tie jumper mouth U3；Work as desired signal
When for " V2/ being opened ", the second stitch and third stitch of tie jumper mouth U3.
Protection diode D1 is connected between NOT gate U1 and external power supply Vcc.
Wherein, when external input standard 5V Transistor-Transistor Logic level signal is high level, signal becomes low level via U1 reverse phase,
And make have voltage on relay U2 coil, and coil attracting electric relay U2 internal switch, the common end COM of relay U2 and normally open end
NO is connected, and for wire jumper mouth U4 by plug jumper cap, can configure signal is earth signal or open circuit signaling, and this signal is sent to 3 ends.
When external input level signal is low level, signal becomes high level via U1 reverse phase, on relay U2 coil
No-voltage, coil are failure to actuate, and relay common end COM and normal-closed end NC are connected, and wire jumper mouth U3 can be matched by plug jumper cap
Confidence number is V1, V2 or open circuit signaling, and this signal is sent to normal-closed end.
In addition, external input power signal VCC can be changed into required voltage V1 by voltage transformation module U5；Voltage transformation module
External input power signal VCC can be changed into required voltage V2 by U6；
It is arranged by wire jumper, realizes the conversion of output signal.By the standard 5V Transistor-Transistor Logic level conversion of board output are as follows: "/
Open ", " V1/ ", " V2/ ", " V1/ is opened ", " V2/ is opened " " opening/ground " signal.
