Signal monitoring device of satellite-borne electronic equipment based on cpci bus

Abstract

The invention provides a signal monitoring apparatus for CPCI bus-based satellite-borne electronic equipment. The signal monitoring apparatus comprises a monitoring system main board, a transfer sub board and a system mechanical structure for fixing and supporting the monitoring system main board and the transfer sub board; the monitored satellite-borne electronic equipment is connected through the monitoring system main board, the transfer sub board, and CPCI electric connectors arranged on the monitoring system main board and the transfer sub board; bus signal acquisition and monitoring output are realized through a JTAG monitoring technology of a programmable logic device FPGA; when a to-be-debugged functional board is mounted on the monitoring apparatus, the to-be-debugged functional board and a satellite-borne electronic equipment mother board can be connected reliably to realize normal communication; whether the to-be-debugged functional board is normal or not can be detected by obtaining the monitoring signal from normal communication, so that independency detection of the module is realized; in addition, the to-be-debugged functional board and the monitoring apparatus are detachable and replaceable, so that batch test can be realized; and the problems of poor debugging property and low debugging safety of the existing CPCI bus-based satellite-borne electronic products are solved.

Description

technical field [0001] The invention relates to the monitoring technology of on-board electronic products, in particular to a signal monitoring device of on-board electronic equipment based on CPCI bus. Background technique [0002] CPCI (Compact Peripheral Component Interconnect, Compact PCI (a standard for defining a local bus)) is a standard bus interface, which has the advantages of high performance, high reliability, and high density. In terms of mechanical structure, the CPCI bus structure adopts standard 3U and 6U board size. With the development of electronic technology, the degree of integration of on-board electronic products has been continuously improved, and the standardization and standardization of products have been continuously improved. The CPCI bus is widely used in on-board electronic products. The electronic products adopting CPCI bus interface have a plug-in mechanical structure, which has good shock resistance and ventilation, and the board can be plu...
