Abstract
The invention relates to an automatic recovering method for power equipment, which is used for an Ethernet power supply system. In the method, an Ethernet exchanger and a power receiving device can mutually transmit packages by establishing a detecting/responding packet protocol in the Ethernet exchanger by using a computer device. If the Ethernet exchanger does not receive packages returned by the power receiving device over the preset times in preset time, the Ethernet exchanger restarts after cutting the Ethernet power supply function; at this moment, the power receiving device automatically recovers because of restart. If the power receiving device does not recover normal operation after restarting for many times, the Ethernet exchanger turns off the Ethernet power supply function and returns a warning signal to the computer device. Thus, not only the system consumption and safety danger can be reduced, but also the reliability of the system can be improved, and personnel monitoring time and cost for onsite repair can be saved. In addition, the quick maintenance mode can reduce danger of window period caused by fault of the power receiving device.
