Embodiment 1

[0040] This embodiment provides a power management system 10, which is applied to communication equipment. Please refer to figure 1 , which is shown as the principle structure of a power management system. The power management system includes a main power module 11 , a backup power module 12 , and a power management module 13 .

[0041] The main power supply module 11 is connected to the communication device, and is simultaneously connected to the backup power supply module 12 and the power supply management module 13 . The main power supply module 11 is used to supply power to the communication device, store its own power supply time parameters, and monitor whether a power input failure occurs in real time. If a power input failure is detected, it outputs an AC alarm signal to the power management system. The module 13, if no power input failure is detected, it outputs an AC power supply normal signal to the power management module 13. In this embodiment, the power input fail...

Embodiment 2

[0054] This embodiment provides a power management method, which is applied to a communication device including a main power module, a backup power module, and a power management module. Please refer to Figure 4 , shown as a flow of a power management method, the method includes:

[0055] S1, monitor in real time whether a power input failure occurs in the main power supply module, if yes, go to step S2, if not, go to step S8.

[0056] S2, output an AC power alarm signal.

[0057] S3: Receive an AC power supply alarm signal, and collect power supply time parameters of the main power supply module and the backup power supply module. The power supply time parameter of the power supply module includes the holding time Thold from when the power supply module detects a power supply input failure to when the power supply output voltage drops out of the normal voltage range, and the delay time Talarm from when the power supply module detects a power supply input failure to outputti...

Abstract

The invention provides a power management system. The system comprises a primary power module, a reserve power module and a power management module. The primary power source module is used for monitoring whether power input failures occur to the primary power source module in real time, alternating current power alarm signals are sent if failures occur, and alternating current power normal signals are sent if failures do not occur. The power management module is used for detecting delay time from the time when the power management module receives the alternating current power alarm signals to the time when the reserve power module opens enable signals and determining whether power time parameters of the power module and the delay time meet a switching time formula preset in the power management module, wherein, the primary power module can be switched to the reserve power module successfully if the parameters and the delay time meet the formula, and the primary power module cannot be switched to the reserve power module successfully if the parameters and the delay time fail to meet the formula, and instructions for reconfiguration of the primary power module are output. The power management system can be switched form the primary module to the reserve module without causing power failure to communication equipment, seamless switching between the primary power module and the reserve power module is achieved, and power consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a power management system and a method thereof. Background technique [0002] With the rapid development of communication technology, communication industry exchanges, transmission, data, wireless local calls, satellite communication, etc., put forward higher requirements for the quality, type, stability and reliability of communication power supply. Generally, the failure of communication equipment affects a small area and is localized. However, if the power supply system is interrupted, the impact will be huge. For example, in the power supply hub, the power supply system is interrupted, and all communication terminals in the entire city; time interruption. All kinds of communication equipment require the power supply voltage to be stable and not allowed to exceed the allowable range of variation, especially for computer-controlled communication equipment. ...
