The invention discloses a distribution automation terminal multi-dimensional state integrated monitoring method. With the help of a self-diagnosis function of a device itself, element-level, board-level and device-level multi-dimensional state online monitoring on the terminal device is realized. The method comprises online monitoring on a key hardware state of the distribution terminal, online monitoring on the distribution automation DC power supply state and online monitoring on a secondary loop of the distribution terminal. The method solves the problems of blind detection and insufficient maintenance on the terminal device caused by regular maintenance, the passed blind regular detection is changed to scientific maintenance for maintenance of the terminal device, the pertinence, the rationality and the operation maintenance efficiency for device maintenance are improved, and the operation maintenance cost is reduced.
