The utility model provides a safe interface arrangement of controller is surveyed to semi -physical simulation ware and quilt, including data signal passageway, analog signal passageway and interface unit, the interface unit includes emulation ware interface module and is surveyed controller interface module, the data signal passageway includes first passageway and second channel, the input and the emulation ware interface module of analog signal passageway are connected, and the output is surveyed controller interface module with the quilt and is connected, the input and the emulation ware interface module of first passageway are connected, and the output is surveyed controller interface module with the quilt and is connected, the input and the quilt survey controller interface module of second channel are connected, and the output is connected with emulation ware interface module. Compared with the prior art, the utility model provides a pair of safe interface arrangement of controller is surveyed to semi -physical simulation ware and quilt carries out safe and reliable's connection to the semi -physical simulation ware with by the survey controller, can provide effectively, last ground simulation environment for being surveyed the controller to debugged for a long time surveying the controller.
