Problems solved by technology

Therefore, the power provided by each backfeed for DPU equipment is limited to a certain range; and DPU equipment usually has 4 channels, 8 channels, 16 channels, 32 channels or even 48 channels, all of which consume a lot of power when working. The power fed back by one or a few CPEs cannot make all the DPUs work

Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0031] see figure 1 As shown, the intelligent power management method of multi-channel backfeed in the embodiment of the present invention is applied to the DPU device, and the DPU device is connected to several CPEs; see figure 2 As shown in the figure, the DPU device communicates with each CPE through one backfeed power receiving module. On this basis, see image 3 As shown, the intelligent power management method of the multi-channel backfeed comprises the following steps:

[0032] S1: DPU equipment preparation, store the output power of the powered back feed module and convert it into the working power required by the CPU (central processing unit) suitable for the DPU equipment; the CPU uses the working power to power on and start, and the CPU The services of all channels are basically initialized, and the services of all channels of t...

Abstract

The present invention relates to the field of multipath reverse power feeding. Disclosed are an intelligent power management method and system for multipath reverse power feeding. The method comprises the steps of: A. all powered reverse power feeding modules send a state indication signal indicating existence of reverse power feeding to a CPU of a DPU device, and all unpowered reverse power feeding modules send a state indication signal indicating nonexistence of reverse power feeding to the CPU; use output power of all the powered reverse power feeding modules as operating power; and B. the CPU sets, using the operating power, services corresponding to all the powered reverse power feeding modules to be in an operating state, the services set to be in the operating state running by using the operating power, and sets services corresponding to all the unpowered reverse power feeding modules to be in a non-operating state. The present invention ensures the power required by services running in a DPU device, thereby implementing intelligent management on the power required by each path of service in the DPU device, so as not only to reduce the consumption of electric energy, but also to make it easy for an operator to manage and use.

Description

technical field [0001] The invention relates to the field of multi-channel back-feeding, in particular to an intelligent power management method and system for multi-channel back-feeding. Background technique [0002] As broadband users have higher and higher requirements for access speed, FTTH (fiber to the home, fiber to the home) develops very rapidly. The main difficulties for operators to fully deploy FTTH networks are the following three points: 1. For non-new construction In some areas, it is difficult to implement fiber perforation and indoor wiring; 2. The terminal installation of indoor optical fiber requires professional skills, and professionals must be sent to the door; 3. The labor cost of installation and maintenance workers is rising year by year. [0003] In response to the above difficulties, the access methods of fiber to the cell and FTTDP (fiber to the distribution point) have shown a situation of simultaneous vigorous development. For FTTDP, it can be ...
