A VXI bus signal control module, equipment and system including the module

Abstract

The invention provides a VXI bus signal control module, equipment and a system comprising the module. The signal control module comprises: an FPGA (Field Programmable Gate Array) unit and an externalinterface unit; the signal control module further comprises: a digital input unit, a signal quantity output unit, a signal control unit and a passive short-circuit signal detection unit. The VXI bus signal control module, the equipment and the system comprising the module solve the problems that the functional modules based on a VXI bus in the prior art do not produce important multiplexed switching value signals of opto-coupler reception, signal output, separation signal control, on-off signal detection and the like so that the signal adapting equipment is complicated in function, low in versatility and scalability and complicated in signal wiring, and are more advanced, clearer in signal connection relations and higher in test accuracy and depth than the prior art.

Description

technical field [0001] The present invention relates to aircraft testing. More specifically, it relates to a VXI bus signal control module, equipment and systems including the module.
