The invention relates to a multi-channel debugging system of a motor train unit. The multi-channel debugging system of the motor train unit is characterized by comprising an FPGA controller and a high-speed analog quantity conversion circuit which are mutually connected, wherein the high-speed analog quantity conversion circuit comprises conversion circuits and regulation circuits which are mutually connected, the multiple conversion circuits are all connected with the FPGA controller, and each conversion circuit is connected with one regulation circuit. The multi-channel debugging system of the motor train unit is integrated inside an electronic device, can simultaneously output multi-path 16-bit high-accuracy analog quantity signals and achieves debugging of multiple paths of signals. The invention further relates to a debugging method for carrying out system debugging by using the multi-channel debugging system of the motor train unit. A signal generator does not need to be installed on site in the debugging process, and the on-site debugging difficulty of vehicle-mounted equipment is lowered.
Description
technical field [0001] The invention belongs to the technical field of on-board electronic equipment for railways, and in particular relates to a multi-channel debugging system capable of dynamically debugging and detecting analog quantities of electronic equipment of a train set. Background technique [0002] There are usually complex internal data inside the railway electronic chassis equipment, especially in the field of real-time control, it is often necessary to quickly detect the internal analog calculation value or detection value to verify the correctness of the analog calculation value or detection value. Relying on the emulator to detect the operation of the internal variables of the board processor can realize the debugging of some internal variables, but the application of this method in on-site debugging is relatively limited. On the one hand, the emulator can only target the internal variables of the processor. When the real-time and rapidity requirements of re...
