The invention provides a fault injection matrix conversion device, and belongs to the technical field of avionics testing, the fault injection matrix conversion device specifically comprises a control unit and a matrix switching unit, the matrix switching unit comprises multiple paths of switches, each path of switch is in a normal state after receiving a normal signal, and each path of switch is in a normal state after receiving a normal signal; the control unit receives a test signal to change the normal state of the switch of the corresponding path into an error state, and the matrix switching unit outputs the final state of each path of switch. Through the processing scheme provided by the invention, full-channel and full-interface testing of the single-board module is realized.

    本申请提供了一种故障注入的矩阵转换装置,属于航空电子测试技术领域,具体包括控制单元和矩阵切换单元,所述矩阵切换单元包括多路开关,每路所述开关接收正常信号呈现正常状态,所述控制单元接收测试信号改变对应路开关的正常状态为错误状态,所述矩阵切换单元输出每路开关的最终状态。通过本申请的处理方案,实现对单板模块的全通道、全接口测试。
