A detection method for cable connection status of small satellite portable power supply and distribution equipment

Abstract

The invention discloses a method for detecting the connection state of a portable power supply and distribution equipment cable of a moonlet, and the method comprises the steps: enabling the whole ground power supply and distribution low-frequency cable network as a body, and employing an unoccupied point on each electric connector as an anti-insertion-error point, wherein the unoccupied points employed by all electric connectors cannot be the same; designing different cable detection loops according to different power supply and distribution equipment designs, and setting an indicating lamp in each detection loop for indicating the connection state of the cable. After a switch of the detection loop is switched on, only when the cable is used in a right way and all electric connectors areplugged in a right way and in a good contact state, can a closed loop be formed, and can the indicating lamp of the corresponding detection loop be turned on. The cable connection state detection loops are independent of other signal loops of portable power supply and distribution equipment, and are powered by an independent power supply, and are completely isolated from other signal loops. According to the design, the method effectively improves the power supply and distribution testing safety and reliability of the comprehensive testing of the moonlet.

Description

technical field [0001] The invention relates to a low-frequency cable network electrical connector insertion detection method widely used in small satellite portable power supply and distribution equipment in the aerospace field. Background technique [0002] The small satellite portable power supply and distribution test equipment is an important part of the small satellite comprehensive test. The output of the equipment inherits the design of some general PLC power supply and distribution equipment, but cancels the control of the power supply path of the regulated power supply inside the equipment, that is, the equipment The number of electrical connectors on the external interface is reduced by 2. The ground power supply and distribution system constructed by portable power supply and distribution equipment also uses a large number of circular sealed electrical connectors of the same type. During the implementation of the power supply and distribution test, there are als...
