Embodiment Construction
[0030] The present invention will be further described below in conjunction with specific examples.
[0031] A four-channel noise signal lossless compression device, such as figure 1 , figure 2 Shown: including data acquisition module, FPGA logic control module, data communication module, DSP algorithm implementation module and Flash storage module, the data acquisition module collects the analog signal output by four noise sensors, and then inputs the FPGA logic control module, FPGA logic The control module controls the global logic sequence, and transmits the digital quantity after analog-to-digital conversion to the DSP algorithm realization module; the DSP algorithm realization module runs a compression algorithm to compress the received digital quantity, and the Flash storage module stores the compressed data, and Real-time transmission to the next-level data communication module. The FPGA logic control module includes an AD acquisition module, a quantization FIFO buf...
