Abstract

The invention discloses a device and method for preventing a POE control system from being halted and still supplying power. The device comprises PSE equipment, a control unit, a monitoring unit and at least one PD equipment, the monitoring unit is used for monitoring the control unit, and when the whole system crashes due to faults of the control unit, the monitoring unit immediately closes the whole power supply system until the faults are eliminated, so that the power supply reliability of the system is ensured.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a device and method for preventing a POE control system from crashing and still supplying power. Background technique [0002] POE (Power Over Ethernet) refers to the use of IP-based terminals (such as IP phones, wireless LAN access points AP, network cameras) without any changes to the existing Ethernet Cat. etc.) while transmitting data signals, it can also provide DC power supply technology for such devices. POE technology can guarantee the normal operation of the existing network while ensuring the security of the existing structured wiring, and minimize the cost. POE is also known as a local area network-based power supply system (PoL, Power over LAN) or Active Ethernet (Active Ethernet), sometimes referred to as Power over Ethernet, which uses existing standard Ethernet transmission cables to simultaneously transmit data and The latest standard specification of ele...
