The Study Of IPC And DSP-based Synchronous Sampling Of AC Data

The synchronous sampling of AC data of power system is of great significance to relay protection, fault diagnosis, system stability analysis and control as well as the parameter measurement of transmission line under operation etc. DSP chip TMS320F2812 , as slave computer, primarily to complete voltage / current phasor synchronization signal acquisition, filtering as well as IPC's communications ; PC547B, as a host computer, is mainly responsible for data reception and processing, human-machine interfaces, function; Dual-port RAM is used for high speed communication and data sharing between PC547B and DSP. The second pulse from GPS via CPLD is converted by DSP into the control signal to control the analog-to-digital converters of synchronous sampling system in different places to synchronously start AC sampling. At the same time, this complete Bluetooth hardware design, and make communication experiment between PC and Bluetooth adapter.
