The present invention provides a general signal transfer device, which includes a panel, a base plate and one or more plug-in boards arranged between the panel and the base plate; multiple first connectors are arranged on the panel, each of the first One end of the connector is used for connecting with an external target device, and the other end is used for connecting with one end of the board, and the signal definition of the first connector is consistent with the signal definition of the external target device; A second connector and a plurality of third connectors, one end of the second connector is connected to the other end of the board, so that the signal definition of the second connector is consistent with the signal of the external target device The definitions are consistent, and the plurality of second connectors are correspondingly connected to one end of the plurality of third connectors according to the arrangement of the interface signals of the external target equipment, and the other end of each third connector is connected to External standard test equipment is connected and categorized by signal type.
Description
technical field [0001] The invention relates to the technical field of testing an integrated electronic system of a spacecraft, in particular to a general signal switching device. Background technique [0002] The interface of the spacecraft integrated electronic system is complex, the number is large, and the interface changes frequently. The interfaces of the same equipment in different stages are inconsistent, and the interfaces of the same equipment in different projects are inconsistent, which leads to the development of test equipment lagging behind the development of equipment. It is difficult to guarantee the reliability of equipment. Testing makes it more difficult to achieve commonality between projects. A common method at present is to connect the interface used by the target device with the corresponding interface of the test device through a cable. However, the use of cable connection has the following disadvantages: 1. Manual operation is required, and incorre...
