Embodiment 1

[0043] Such as figure 2 As mentioned above, a signal feedback method provided in this embodiment, the method includes:

[0044] Step 201: Collect the input voltage of the powered device when the output voltage of the power supply device supplies power to the powered device;

[0045] Step 202: Feedback a signal corresponding to the collected input voltage to the power supply device for adjusting the output voltage.

[0046] In step 201 of this embodiment, after a series of operations such as detection and classification of the power receiving device, the power supply device determines that the power receiving device can communicate with the power supply device, and at the same time determines the required function of the power receiving device. After consumption, the power supply equipment provides output voltage to power the powered equipment. The output voltage provided by the power supply equipment can ensure the normal operation of the powered equipment as long as there i...

Embodiment 2

[0057] Such as image 3 As mentioned above, a power supply method provided in this embodiment includes:

[0058] Step 301: Output voltage to power receiving equipment

[0059] Step 302: according to the corresponding signal fed back;

[0060] Step 303: Adjust the output voltage.

[0061] In step 301, the power supply device outputs a voltage to the power receiving device, and the power receiving device collects the input voltage provided by the power supply device, and then feeds it back to the power supply device in the form of a corresponding voltage signal;

[0062] In step 302, the corresponding signal fed back can be received by the power supply device itself, or by a third party. In this embodiment, preferably, the signal is received by the power supply device itself. In the above step 302 The signal received by the power supply device includes at least one of a voltage value signal and a voltage difference signal, and at the same time, the signal received by the powe...

Embodiment 3

[0076] This embodiment also provides another power supply method, which specifically includes:

[0077] In this embodiment, the preferred power supply device itself receives the signal fed back by the power receiving device through the network cable. When the signal received by the power supply device is a digital signal and the digital signal is a voltage value signal, the digital signal received by the power supply device will Convert directly to a recognizable voltage-regulated signal without digital-to-analog conversion.

[0078] When the signal received by the power supply equipment is a digital signal and the digital signal is a voltage difference signal, the power supply equipment directly converts the received digital signal into an identifiable and identifiable voltage regulation signal.

[0079] In this embodiment, after converting the received signal into an identifiable voltage regulation signal, the power supply module in the power supply terminal provides a speci...

Abstract

The present invention provides a method for signal feedback and apparatus thereof, a method for power supply and equipment thereof, and a method for controlling and system thereof. The present invention collects an input voltage of a power receiving equipment, and feeds back the corresponding signal to a power supply equipment according to the collected input voltage, and the power supply equipment adjusts an output voltage according to the received signal.

Description

technical field [0001] The invention relates to the field of power supply, in particular to a signal feedback method and device, a power supply method and equipment, a control method and a system. Background technique [0002] With the promulgation of IEEE802.3at (the high-power standard of the American Institute of Electrical and Electronics Engineers), Power over Ethernet (POE) technology is becoming more and more mature, and network equipment with PSE (Power Supply Equipment) functions can serve more and more Many IP (Internet)-based terminals (such as IP phones, wireless LAN access points AP, network cameras, etc.) transmit data signals while supplying power, which also makes PD (Power Device, Power receiving equipment or power receiving module) products have developed rapidly. [0003] At present, POE power supply supports up to 100m network cable. Because of the impedance on the network cable, there will be a large voltage drop when the voltage sent by the PSE reaches...
