Abstract

The invention discloses a fault simulation device of a fiber channel avionics environment (FC-AE)-1533 device, which relates to the fault simulation device. In order to simulate a fault of the FC-AE-1533 device so as to detect the fault of the FC-AE-1533 device, a Qsys system is built inside a programmable logic device. An NIOSII processor in the Qsys system is used for transmitting a control command to an optical fibre interface module; a PCIe module is used for receiving the fault injected from a fault simulation host computer and carrying out data interaction with the simulation host computer, and the optical fibre interface module is used for carrying out 8B / 10B encoding and transmitting on the data, transmitting the injected fault, and carrying out decoding and CRC (cyclic redundancy check) on the received data. The fault simulation device of the FC-AE-1533 device disclosed by the invention can be widely applied to an avionic device, a fighter plane, a civil airplane, naval vessels and other occasions with the device meeting the FC-AE-1533 protocol, and can carry out the work such as maintaining, testing, fault overhauling and the like on the product.

Description

technical field [0001] The invention relates to an equipment failure simulation device. Background technique [0002] With the development of aerospace electronic buses, the interconnection performance between devices and the requirements for data throughput are also gradually increasing, and the FC-AE-1553 bus based on Fiber Channel technology has advantages in data transmission bandwidth and network performance. It has become the military bus standard following the MIL-STD-1553B bus, and will be more and more used in spaceborne, shipborne, airborne and other equipment. With the in-depth research on FC-AE-1533, FC-AE-1533 equipment will emerge in large numbers, and the problem of lack of bus test means becomes increasingly prominent. At present, there is no FC-AE-1533 equipment fault simulation device that can test FC-AE-1533 through fault injection in the domestic market. Contents of the invention [0003] The present invention aims at performing fault simulation on FC...
