Accompanying drawing explanation
Fig. 1 is the circuit theory diagrams of the present invention.
Detailed description of the invention
Below the present invention is described in further details.See Fig. 1,
A kind of TT&C system discrete output signal conditioning module, adjusts for the standard 5V Transistor-Transistor Logic level exported by TT&C system
Reason is flight control computer required analogue signal when test, this conditioning module input lead up to resistance R1 ground connection,
The coil a end of not gate U1 and relay U2 of separately leading up to is connected, and the coil b end of this relay U2 is connected with external power supply Vcc,
Common port COM is connected with second stitch of wire jumper mouth U3 as output port, normal-closed end NC, the of normally opened end NO and wire jumper mouth U4
One stitch connects, the second stitch ground connection of this wire jumper mouth U4；First stitch of described wire jumper mouth U3 and the 3rd stitch respectively with electricity
Pressure modular converter U5 and voltage transformation module U6 connects.
When desired signal is for "/open ", first stitch of tie jumper mouth U4 and the second stitch；When desired signal is
Time " V1/ ground ", first stitch of tie jumper mouth U4 and the second stitch, first stitch of tie jumper mouth U3 and the second stitch；
When desired signal is " V2/ ground ", first stitch of tie jumper mouth U4 and the second stitch, second stitch of tie jumper mouth U3
With the 3rd stitch；When desired signal is for " V1/ opens ", first stitch of tie jumper mouth U3 and the second stitch；Work as desired signal
During for " V2/ opens ", second stitch of tie jumper mouth U3 and the 3rd stitch.
Protected diode D1 it is connected between not gate U1 with external power supply Vcc.
Wherein, when outside input standard 5V Transistor-Transistor Logic level signal is high level, signal becomes low level via U1 is anti-phase,
And make to have on relay U2 coil voltage, coil attracting electric relay U2 internal switch, the common port COM of relay U2 and normally opened end
NO connects, and wire jumper mouth U4 is by plug jumper cap, and configurable signal is earth signal or open circuit signaling, and this signal is delivered to 3 ends.
When outside input standard 5V Transistor-Transistor Logic level signal is low level, signal is via the anti-phase high level that becomes of U1, relay
No-voltage on device U2 coil, coil is failure to actuate, and relay common port COM and normally opened end NO connects, and wire jumper mouth U3 is jumped by plug
Line cap, configurable signal is V1, V2 or open circuit signaling, and this signal is delivered to normal-closed end.
Additionally, 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；
Arranged by wire jumper, it is achieved the conversion of output signal.The standard 5V Transistor-Transistor Logic level that board exports is converted to: "/
Open ", " V1/ ", " V2/ ", " V1/ opens ", " V2/ opens " " opening/ground " signal.
