【Abstract】 With rapid development of electronic technology, digital signal processor (DSP) and complex programmable logic device (CPLD) are used widely. We have been aware of their high-speed character and powerful ability of processing data increasingly. It has been a trend that using DSP and CPLD to measure and analyze the parameters of power line network timely. In this paper, the power line network parameter measuring meter, is a new generation of power line network data meters, which take use of DSP(TMS320VC5416) and CPLD(XC95288XL) as its key part and has intensive integration of sampling, analyzing, counting and communicating. This paper consists of three parts as follow:1. Constructing a power line network measuring meter system based on DSP and CPLD; researching the measuring principle, realizing method and testing error analyzing of routine power parameter (voltage, current , frequency , phase , active power ,reactive power , distortion degree etc.) and harmonics in details. 2. Discussing the Ethernet principle and realizing communication in Ethernet network in a system with DSP and CPLD; introducing the communication principle and realizing method using wireless GSM (GPRS), serial interface and HPI in brief. 3. Introducing the bootloading principle of DSP and the realizing method of parallel bootloading with 16bits.The test running result of the system reaches the expectant effect and purpose. The system has very high veracity and flexibility. The research method of this paper has been proved to be valid.更多还原
