Standardized interface device suitable for satellite-borne electronic equipment

The objective of the invention is to provide a standardized interface device for satellite-borne electronic equipment. All data transmission functions are integrated in multiple data channels, and each data channel can be backup for each other; an interface comprises multiple digital I/O channels so as to meet requirements of a satellite-borne system for clock pulse data and stand-alone state data of each equipment; the interface comprises an OC instruction port which can control on and off of the equipment; the interface comprises an IO port which can detect the state of the equipment; and the interface also comprises an analog quantity channel so as to meet the requirements of the satellite-borne system for analog quantity acquisition. An interface controller can manage and schedule all the data channels and the ports. Channel characteristics and communication contents of all the data channels can be optionally configured via simple configuration, and gating and expansion functions of analog acquisition channels can be realized so that satellite-borne electrical connection relations can be simplified, and batch production and shelf-type product purchasing of the satellite-borne electronic equipment can be realized.
