The present invention discloses a power device monitoring system based on a smart power grid. The system comprises a signal detection unit, a signal processing unit, a signal transmission module and amanual diagnosis unit which are in circuit connection in order. The signal detection unit, the signal processing unit and the signal transmission module communicates with a power supply. The signal processing unit is formed by an integration circuit operational amplifier, a signal converter and a controller. The signal transmission module is internally provided with a photoelectric coupler. A plurality of sensors can detect a state of a power device in real time and perform real-time transmission processing, so that effects of high reliability and accurate monitoring are achieved.
Description
technical field [0001] The invention relates to a monitoring system, in particular to a smart grid-based power equipment monitoring system. Background technique [0002] Power equipment is the most important core part of the smart grid, and its normal operation is the fundamental guarantee of grid security.
