There is supply access to occur carrying out umbilical connector under the abnormal conditions of open circuit or short circuit falling off control and burble point connector
Separation control causes control to fail；Simultaneously acquire satellite flight plug state avoid satellite flight plug leak insert or misplug for
It protects and carries out umbilical connector under the abnormal conditions of plug and fall off control, correlation function failure after causing satellite to go up to the sky.Satellite
Separation connector separation control is similar, and the control flow present apparatus for telling about apparatus of the present invention is easy to operate, convenient.
Fig. 6 is that satellite umbilical connector of the invention falls off control flow chart.Including control preparation and the control two that falls off
Part, wherein control prepares to include step (1), (2)；The control that falls off includes (3)~(8).Concrete operations include following sequence step
It is rapid: ensure satellite dispatch from foreign news agency power-off in the case where, when tester remotely send fall off control warning order after, (1) this hair first
The control software of bright device judges whether to be in emission state by satellite that (after the state is switched on by device, tester remotely bristles with anger
Enable selection), if it is determined that satellite is in emission state, device will judge the state of satellite flight plug, only complete in satellite
In the case that portion's flight plug is plugged, just can be carried out umbilical connector fall off control avoid satellite flight plug leak insert or accidentally
It is inserted as carrying out umbilical connector under the abnormal conditions of protection plug falling off control, correlation function failure after causing satellite to go up to the sky.
If ignoring this step automatically in the case that satellite is in test pattern.(2) fall off to electricity control the impedance of power link into
Row measurement, avoids carrying out the umbilical connector control that falls off under the abnormal conditions that open circuit or short circuit occurs in supply access causing to control
System failure, only in the normal situation of power link, just can be carried out the control that falls off of umbilical connector.(3) programmable power supply
For electrically connecting；(4) it falls off and controls main power source, is i.e. 1 power supply module 1 of programmable power supply and power supply module 2 rises electricity；(5) judge program-controlled
Whether the power supply submodule of power supply is normal, automatically continues if normal in next step, is otherwise automatically changed to the control backup electricity that falls off
Source (i.e. programmable power supply 2), using fall off control backup battery execute electricity fall off control with use main power source be identical
Control flow；(6) it carries out umbilical connector electricity by the actuating relay that falls off of the electricity in control switch module and falls off control；
(7) judge whether pull-off plug normally falls off, the electricity that umbilical connector is completed if just falling off falls off control, if fallen off
It is unsuccessful, then need to be implemented de- control flow by force；(8) control flow is taken off by force.It only falls off to control in umbilical connector electricity and lose
In the case where effect, just executes the de- control flow by force: initially entering main part and take off control flow, the power supply module 2 of programmable power supply 1 by force
Electricity is risen, whether the power supply submodule for judging automatically programmable power supply is normal, and the mechanical system de- by force of launching tower is controlled if normal
The electromagnetic valve switch of gas supply carries out the mechanical strong de- control of umbilical connector, then judges automatically whether pull-off plug normally takes off
It falls, controlling if normal terminates；Enter backup de- control flow by force if abnormal；The strong de- control of backup takes off by force control with main part
Process processed is consistent, and difference is 2 liters of electricity of power supply module using programmable power supply 2, and fall off control knot if taking off control successfully by force
Beam, the control that falls off if strong de- control failure terminate to interrogate topic side by side, complete machine if umbilical connector normally falls off
Tool takes off by force control, and control terminates；If fall by force it is unsuccessful, control terminate, check problem.
Fig. 7 is that satellite separation connector of the invention separates control flow chart.Satellite separation connector of the invention
Separating control flow includes that control prepares and separate control two parts, wherein control prepares to include step (1), (2)；Separation control
Including (3)~(8).Concrete operations comprise the following sequential steps: in the case where ensuring the power-off of satellite dispatch from foreign news agency, when tester is long-range
Transmission falls off control warning order after, the control software of (1) apparatus of the present invention first judge satellite whether be in emission state (should
After state is switched on by device, tester remotely sends instructions selection), if it is determined that satellite is in emission state, then forbid executing
Divide slotting lock out operation, prevent maloperation, only in the case where satellite is in test, just can be carried out separation connector separation control
System.(2) impedance of the power link of all electrically separated controls is measured, avoids occurring in supply access breaking or short circuit
Device separation control is electrically connected under abnormal conditions causes control to fail, only in the normal situation of power link, Cai Nengjin
The separation of row separation connector controls.(3) programmable power supply is for electrically connecting；(4) separation control main power source, i.e. programmable power supply 1 supply
Electric module 1 and power supply module 2 rise electricity；(5) judge whether the power supply submodule of programmable power supply normal, if normal automatically after
It is continuous to be otherwise automatically changed to separation control backup battery (i.e. programmable power supply 2) in next step, electricity is executed using separation control backup battery
It is identical control flow that separation, which controls and uses main power source,；(6) pass through the electrically separated movement in control switch module
Relay carries out separation connector electrically separated control simultaneously；(7) judge whether breakaway plug normally separates, if positive separation
The electrically separated control for completing separation connector, if separation is unsuccessful, control terminates, and checks problem.(8) separation control is standby
Part power supply separates control flow.It is identical that control flow is separated with main part power supply.It is completed if separation connector normally separates
Separation control, control terminate；If separation control is unsuccessful, control terminates, and checks problem.
