Embodiment Construction

[0033] Specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0034] The present invention retains the design of the satellite power supply of the traditional detachable cable, the satellite service test computer interface and the control quantity, state quantity and analog quantity contact of the cable station, rationally utilizes the limited contact resource of the detachable cable, and fully considers the electromagnetic compatibility of strong and weak currents It integrates the traditional detachable cable with the functions of equalized charging of satellite battery, satellite emergency power off, primary bus measurement, carrier separation command and status acquisition, etc., and finally realizes the detachment of the integrated design. Plug in the cable network.

[0035] like figure 1 As shown, the structure of the detachable cable network of the present invention is as follows: it incl...

Abstract

The invention relates to a microsatellite unplugged cable network, which solves the problem that the design of a star catalogue plug is difficult due to structural characteristics of the microsatellite of small volume, body-mounted solar cell array and the like. In the prior art, in order to preserve the star catalogue plug, only a star catalogue plug interface is arranged on the body-mounted solar cell array, which necessarily damages the integral structure of the satellite body-mounted solar cell array. In order to meet the task requirement of the microsatellite and overcome the defects in the prior art, the microsatellite unplugged cable network integrates the satellite star catalogue and the microsatellite unplugged cable, maintains satellite power supply of the traditional unplugged cable, a satellite task test computer interface and controlled quantity, state quantity and analog quantity contacts of a wired station, reasonably utilizes limited pin resources of the unplugged cable, and successfully integrates the traditional star catalogue plug and star catalogue cable into the unplugged cable network according to the electromagnetic compatibility of strong and weak current and pin multiplexing of an electric connector.

Description

technical field [0001] The invention relates to a micro-satellite detachable cable network, which can be applied to the test of micro-satellites in the aerospace field. Background technique [0002] In the comprehensive test process of the satellite, there are two kinds of wired interfaces between the ground test equipment and the satellite: one is the satellite star list plug interface, and the cable connected to it is called the star list cable; the other is the satellite shedding plug interface, which is connected to it The cable is called a plug-in cable. In the traditional design of satellites, test tasks such as battery equalization charging, satellite emergency power-off and primary power measurement are completed through star catalog cables; satellite power supply, star service test computer interface, and cable station control, state and analog measurement Wait for the task to be done by shedding the cable. When the volume of the satellite is large, the proportion...
