Ethernet network standby power supply module, device and system

Abstract

The invention discloses an Ethernet network standby power supply module, a device and a system, and relates to the technical field of power supply devices and systems. The standby power supply module comprises a power supply monitoring and display module, a battery and protection circuit module, and a power output voltage-stabilizing and voltage-boosting module, wherein the power supply monitoring and display module is used for monitoring inputted power supply, displaying the working state of the power supply and the value of the inputted power supply, and carrying out charging or discharging control on the battery; the battery and protection circuit module is used for receiving the power supply outputted by the power supply monitoring and display module and the battery carries out charging or discharging; and the power output voltage-stabilizing and voltage-boosting module is used for receiving the power supply outputted by the power supply monitoring and display module or the battery and protection circuit module and outputting the power supply after voltage-stabilizing and voltage-boosting processing to the module in need of power supply. As the standby power supply module is used and a POE (Power Over Ethernet) separator or a POE injector is configured, uninterrupted power supply can be provided for the IP equipment or the POE equipment in the Ethernet network, and running stability of the equipment is improved.

Description

technical field [0001] The invention relates to the technical field of power supply devices and systems, in particular to an Ethernet backup power supply module, device and system. Background technique [0002] PoE (Power over Ethernet) is a next-generation Ethernet power supply network further developed based on the Ethernet network standard IEEE802.3. The biggest difference between PoE and the original Ethernet is that the original Ethernet can transmit data at a rate of 10M / 100M / 1000MHz within a distance of 100M on a network cable of a specific specification. The basic composition of Ethernet is as follows Figure 4 shown. [0003] The new generation of Ethernet power supply network can not only transmit data at a rate of 10M / 100M / 1000MHz within a distance of 100M on a network cable of a specific specification, but also transmit 48VDC power in the same network cable, which can provide maximum The power supply can reach 15.4W (IEEE802.3af) or 30W (IEEE802.3at) for each R...

Problems solved by technology

[0005] (2) Because traditional IP equipment requires an external power supply, there must be an AC power socket within the range of the power supply cable where the IP equipment is installed. Otherwise, an AC power supply must be specially installed, and the need to arrange an AC power supply will increase additional materials and installation labor. cost, these costs can be saved for the installation of PoE equipment

[0006] (3) Traditional IP equipment requires an external 110VAC-240VAC external power supply, which cannot be used in many special places such as humid environments, dusty and explosive environments, outdoor environments, or where it is difficult to arrange or install AC power. Use this type of IP device

[0012] PoE equipment has the same disadvantages as traditional Ethernet IP equipment: when the power supply of PoE equipment from the PoE power supply network fails, or the PoE system itself fails or the Ethernet network fails, it cannot operate

[0015] At present, the input of the mobile power supply can only accept the 5VDC power transmitted by the USB interface, and the output is also 5VDC.

At the same time, it does not have the ability to separate power and data from the PoE network, so it cannot function as a backup power supply in Ethernet or Ethernet power supply networks
