The utility model relates to a power distribution automation terminal comprising a DSP (Digital Signal Processor). The signal input end of the DSP is respectively connected with a voltage transformer, a current transformer and a switching value input circuit, the signal output end of the DSP processor is connected with a relay, the signal input and output ends of the DSP are accessed to the Ethernet through a W5100 chip and the DSP is connected with a memory card. In the utility model, Due to the adoption of the DSP serving as a central processing unit and the combination of an analog switch, the power distribution automation terminal can accurately measure a multi-channel three-phase voltage and a multi-channel three-phase current and monitor various impulse and state quantities, has the advantages of high processing speed, high accuracy in measurement, small size, high reliability, low cost, lower overall system investment and obvious economic benefit. In the utility model, as an inner FLASH and the memory card of the DSP are adopted to store the parameters required by measurement, the problem caused by an external memory EEPROM (Electrically Erasable Programmable Read-Only Memory) due to data loss is effectively avoided and the reliability of the terminal is further improved.
