Multi-spacecraft series state detection circuit and its realization method

Abstract

The invention provides a multi-spacecraft series connection state detection circuit and an implementation method. When the contacts of a spacecraft 1 and a spacecraft 2 are not connected, a resistor R1 and a resistor R2 are connected in parallel and thereafter are connected in series with a resistor R3; when the contacts of the spacecraft 1 and the spacecraft 2 are connected, the resistor R1 is disconnected, the resistor R2 is connected in series with the resistor R3, and the resistor R3 is grounded; and the series connection state of the spacecraft 1 and the spacecraft 2 can be judged throughdetecting a state output voltage P at the resistor R3. The implementation principle topology of the multi-spacecraft series connection state detection circuit is simple and easy to understand; the engineering implementation of the multi-spacecraft series connection state detection circuit is easy; and the multi-spacecraft series connection state detection circuit has an important engineering application value for multi-spacecraft series use.

Description

technical field [0001] The invention relates to the technical field of multi-spacecraft series connection, in particular to a multi-spacecraft series connection state detection circuit and an implementation method. Background technique [0002] At present, the form of multi-space power supply is a subordinate relationship, that is, one spacecraft H supplies power to the remaining N spacecraft. In order to detect whether the spacecraft H is in a power supply relationship with the other N spacecraft, it is only necessary to use a simple resistor voltage divider at the power supply output port of the spacecraft H to realize the corresponding state quantity. By detecting whether these N state quantities are at a high level, it can be known whether spacecraft A is in a power supply relationship state with the remaining N spacecraft. Such as figure 1 As shown, the spacecraft 1 and the spacecraft 2 are in a subordinate relationship, and the spacecraft 1 can supply power to the sp...

Problems solved by technology

Especially when the independent bus voltages of spacecraft 1 and spacecraft 2 are equal, the state output value max(V1, V2)×R1 / (R2+R1)=min(V1,V2)×R1 / (R2+R1), The output value is always a single value, there is no way to detect in which state the two are interconnected
