Description

Supply multiple DC output power connection devices from Ethernet powered devices

This creation is about a kind of DC output power connection device from the Ethernet powered device, especially a different voltage generated from the Ethernet Power Supply Technology (POE) architecture, and provides external device connection to allow Use a single POE power supply to connect power to external devices such as separate or connected devices.

Power over Ethernet (POE) is a technology that can transmit power and data to a device through a twisted pair cable in an Ethernet network. Devices such as VoIP, wireless base stations, webcams, hubs, computers, etc. can be powered by POE technology, as there is no need for additional power outlets for electronic devices that can be powered by Ethernet. It can be used, so at the same time, the time and money for configuring the power cord can be saved, and the cost of the entire device system is relatively reduced.

The reason is that the main purpose of this creation is to provide power to the Ethernet Power Module (PD Module) from the Power Source Equipment (PSE) under the Ethernet Power Supply Technology (POE) architecture. The rectifier diode and POE voltage conversion module distributes the power output, and can provide power to multiple sets of external devices such as separate (farther away) or connected (closer).

In order to achieve the above objectives, the creation uses the following technical means:

A plurality of DC output power connection devices are supplied from an Ethernet power receiving device, wherein Under the network power supply technology (POE) architecture, the power source equipment (PSE) provides power to the Ethernet PD Module, and the PD Module converts the signal into a conformance. The POE communication protocol IEEE802.3AF, AT and POH standards, and then distribute the power output, and finally adjust the voltage through the internal module to provide power to multiple sets of external devices with different voltages.

In order to let your review board have a better understanding of this creation, Zize elaborated on the creation as follows:

The first picture: the circuit block diagram of this creation.

The second picture is the internal circuit block diagram of the Ethernet module of the author.

Please refer to the circuit diagram of the creation shown in the first figure, in which the Power Source Equipment (PSE) 10 is powered by the RJ-45 network route to the Powered Device Module (PD). Module) 20, as shown in the second figure, the bridge rectifier 21 inside the Ethernet power receiving module 20, rectifies and filters the signal source, and then supplies power through the Ethernet. The (POE) conversion module 22 converts the signal into an IEEE802.3AF, AT and POH standard conforming to the Ethernet Power over Ethernet (POE) protocol, and distributes the power output (the voltage is 57V→19V) through the internal module. Adjusting the voltage (this voltage can be from 19V → 12V or from 19V → 14V...) to provide power to multiple sets of external devices 30 of different voltages, such as separate (farther away) or connected (closer) 40, 50 to use.

The apparatus generates a first power source to allow a second power source connection, wherein the second power source connection may have the same voltage as an Ethernet powered device (PD) or may have a different voltage. The location of the second power connection depends on the voltage given by other connected devices. The second power connection is usually an external main system, which allows the power supply to be connected from the POE to the location. Other power supplies used.

At the same voltage, as a power connection for a Power over Ethernet (POE) connected device, the other power connections are located at the output of the voltage regulation function of the system.

At different voltages, it is the power connection for the Ethernet Powered (POE) connected device, and the other power connections are located before the voltage adjustment function of the system. The possible way to connect the power supply to other devices to control the power state of other connected devices is controlled.

In summary, the author provides multiple DC output power connections from the Ethernet powered device, which generates a different voltage from the Ethernet Power System (POE) architecture and provides an external connection to allow use. A single POE power connection separates or powers the connected device. The practical effect is undoubted, and this creation has never been made public or has been seen in other publications. It has already complied with the provisions of the Patent Law and has filed a patent application according to law.
