Embodiment 1

[0041] figure 1 The implementation process of the power supply control method of the remote power supply switch provided by the first embodiment of the present invention is shown, and the details are as follows:

[0042] In step S101, detecting the output power of the remote power supply switch for remote power supply;

[0043] Specifically, the remote power supply switch in the embodiment of the present invention means that when the remote power supply switch is connected to other devices through a cable, it provides data communication through the cable and also provides power through the cable. Wherein, the equipment connected to the remote power supply switch may be a wireless access station, an IP camera, an IP phone, and the like.

[0044] Wherein, the output power of the remote power supply switch for remote power supply can be obtained by summing the power required by the power receiving end device detected during POE power supply, or can directly check the remote outp...

Embodiment 2

[0056] figure 2 The implementation flow of the power supply control method of the remote power supply switch provided by the second embodiment of the present invention is shown, and the details are as follows:

[0057] In step S201, the number of power receiving end devices connected to the current port is detected.

[0058] Specifically, the power of the receiving end equipment connected to the same remote power supply switch generally includes the first working power and the second working power, for example, the telephone includes the standby working power and the talking working power, and the camera includes the camera working power and sleep power etc.

[0059] In the embodiment of the present invention, by detecting the number of power receiving end devices connected to the port of the remote power supply switch, if it is detected that the number of power receiving end devices is less than the predetermined number, it is not necessary to compare the output power of th...

Embodiment 3

[0070] image 3 The implementation flow of the power supply control method of the remote power supply switch provided by the third embodiment of the present invention is shown, and the details are as follows:

[0071] In step S301, the output power of the remote power supply switch for remote power supply is detected.

[0072] In step S302, when the output power of the remote power supply switch for remote power supply is less than the first power, charge the rechargeable battery of the power receiving end device.

[0073] In step S303, when the output power of the remote power supply switch for remote power supply is greater than the second power, acquire a value at which the output power of the remote power supply switch for remote power supply exceeds the second power.

[0074] Specifically, in Embodiment 1, it is introduced that when the output power of the current remote power supply switch exceeds the second power, a control command is sent to the rechargeable battery o...

Abstract

The invention provides a power supply control method and apparatus for a remote power supply switch. For the power supply control apparatus for a remote power supply switch, charging batteries are arranged at part of or all the receiving end devices. The power supply control method for a remote power supply switch includes the steps: detecting the output power for performing remote power supply for the remote power supply switch; when the output power for performing remote power supply for the remote power supply switch is smaller than a first power, charging the charging batteries of the receiving end devices; and when the output power for performing remote power supply for the remote power supply switch is greater than a second power, selecting the charging batteries to supply power for the receiving end devices. The power supply control method and apparatus for a remote power supply switch can effectively solve the problems that when the remote power supply switch is connected with a large amount of devices, the performance of the receiving end devices is easily reduced and restarting of the receiving end devices easily occurs.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a power control method and device for a remote power supply switch. Background technique [0002] A remote power supply switch refers to a remote power supply switch that uses POE (Power Over Ethernet) technology to provide power for terminals. Among them, POE refers to the transmission of data signals for some IP-based terminals (such as IP phones, wireless LAN access points AP, network cameras, etc.) without any changes under the existing Ethernet Cat. At the same time, 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. [0003] A complete POE power supply system includes a power supply device and a power receiving device connected to it through a twisted pair. Limited by the wire diameter, the typi...
