Abstract
A power-off protection system used in a multi-node system includes a detecting module. The detecting module obtains voltage, current and temperature information of all of the nodes and power supplying units in the multi-node system periodically. A determining module determines if any node from the nodes and power supplying units is abnormal. A control module controls a switch connected with the node that is abnormal to turn off, thereby turning off power source connected with the node that is abnormal.

A power-off protection system used in a multi-node system, the multi-node system comprising a plurality of nodes and a plurality of power supplying units, the power-off protection system comprising:
- a detecting module obtaining voltage, current, and temperature information of the nodes and the power supplying units in the multi-node system periodically;
- a determining module determining if any node from the nodes and any power supplying unit from the power supplying units are abnormal;
- and
- a control module controlling a switch connected with the node that is abnormal to turn off, thereby turning off power source connected with the node that is abnormal.
A power-off protection method, comprising:
- obtaining voltage, current, and temperature information of all nodes and power supplying units in a multi-node system periodically;
- determining if any node from the nodes and any power supplying unit of the power supplying units is abnormal;
- and
