Full-digital power distribution monitoring device

The invention relates to a full-digital power distribution monitoring device comprising a shell. The front surface of the shell is provided with a display screen. The top part of the shell is provided with a voltage sensor. The internal part of the shell is provided with a full-digital electric wave identification module, a digital signal processing unit and a storage device. The voltage sensor is connected with the full-digital electric wave identification module and the digital signal processing unit through an amplification filter circuit and an A/D sampling circuit in turn. The digital signal processing unit is respectively connected with the storage device and the display screen. The back surface of the shell is also provided with a wristband. Voltage or current waveform in an electric power system can be monitored and the can be fully digitalized via the full-digital electric wave identification module. The full-digital power distribution monitoring device is worn on a hand wrist via the wristband so that operation is facilitated, and monitoring and debugging of a power distribution automatic terminal are facilitated for work personnel. Besides, data are displayed on the display screen and the data are stored via the storage device so that requirements of data inspection are facilitated.
