The application discloses a pulse output device for a train vehicle charger test. The pulse output device for the train vehicle charger test comprises a controller used for transmitting an initial control signal to a processor module through a signal transmission module, the processor module used for analyzing the initial control signal and a pulse conversion module used for generating a corresponding PWM (Pulse-Width Modulation) pulse signal according to the analyzed control signal when the processor module receives a starting instruction, and sending the corresponding PWM pulse signal to a charger to be tested. According to the application, after transmitted through the signal transmission module, the initial control signal sent through the controller is analyzed by the processor module to obtain the analyzed control signal, the processor module controls the pulse conversion module to generate corresponding PWM pulse signal according to the starting instruction and send the corresponding PWM pulse signal to the charger to be tested. The process of generating and outputting the corresponding PWM pulse signal by using the pulse output device does not require the participation of testing personnel, so that the cost is saved in the charger testing process.
Description
technical field [0001] The invention relates to the technical field of signal generators, in particular to a pulse output device used for testing a charger for train vehicles. Background technique [0002] The auxiliary power supply is an important part of the train vehicle, and the charger is one of the core components of the auxiliary power supply. [0003] In the prior art, for the test of the charger, the SIV / DCU chassis is used as the accompanying test product, and the PWM (Pulse Width Modulation, pulse width modulation) pulse actually used on the train vehicle is used to achieve the test purpose. This method has the advantage that the interface is consistent with the real operating environment of the DUT, but it requires the participation of SIV / DCU designers, which is costly, inconvenient to integrate with other test resources, and high maintenance costs. [0004] Therefore, how to save cost in the charger testing process is a technical problem that needs to be solve...
