Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is an overall construction drawing of the present utility model, comprise ARM9 processor 1, the SDRAM 4 (memory) of Nand Flash 3 (memory), the 64MB of 256MB, power circuit 6, Ethernet card 5, the multi-functional noise signal Acquisition Instrument 2 of HS6298 type, Ethernet and long-range PC to noise signal enforcement monitoring.The multi-functional noise signal Acquisition Instrument of HS6298 type 2 is connected with the feature board serial ports by RS232 Serial Port Line 7, and the Ethernet card 5 of feature board is connected with long-range monitoring PC by Ethernet.ARM9 processor 1 links to each other with memory 3,4, power circuit 6, Ethernet card 5, the multi-functional noise signal Acquisition Instrument 2 of HS6298 type.
