The invention discloses a ground verification platform based on heterogeneous parallel multiple buses. A test is conducted in a plurality of regions. A machine cabinet is assigned to each region. The machine cabinets and a work station are connected through an Ethernet bus to form a local area network. Each machine cabinet comprises a PXI chassis generating a signal source and a signal conditioning chassis. An embedded controller is used to transmit parameters, generating commands and control commands of a signal source board. Meanwhile, each signal conditioning chassis uses a modularized signal conditioning board for analog signal conditioning. An analog digital bus is designed, and analog signal interaction is completed by means of an analog digital bus backboard. A control board is used to complete selection of a control signal and a display signal. Via the above way, test regions and test functions can be added flexibly according to needs, and a modularized, reconfigurable and extensible structural design is implemented.
