| description | The invention provides a multi-source data synchronous acquisition system, comprising a signal acquisition module, a signal processing module and a data output module. The signal acquisition module isa multi-source signal sensor, which is used for acquiring multi-source data; the signal processing module comprises a synchronous pulse synthesizer, an ARM processor and an FPGA. The data output module comprises a ground station and a local storage; Using a synchronization pulse signal output from the synchronization pulse synthesizer as an interrupt request signal of the ARM processor, When theARM processor receives the interrupt request signal, the ARM processor synchronously collects the multi-source data in the current buffer, transmits the FPGA for fusion processing, and transmits the fusion data to the ground station or the local storage. The invention can realize hard synchronization of multi-source signal sensors through synchronous triggering of synchronous pulse synthesizer.
