Embodiment Construction

[0029] In order to make the purpose, content, and advantages of the present invention clearer, the specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0030] The cabinet is composed of various board cards, and the present invention aims to adopt a strategy: through the control module of the cabinet to schedule whether other boards are running, so as to reduce the total power consumption of the cabinet and increase the service life of the cabinet. The board adopts a multi-processing architecture: a processor receives user's instruction information through I2C, and controls the power-on and power-off of other processors, thereby realizing flexible power management and control functions.

[0031] In order to solve the problems of the prior art, the present invention provides a power management and control method based on an I2C bus-based multi-processor architecture. The power managemen...

Abstract

The invention belongs to the technical field of cabinet system health management, and particularly relates to a multiprocessor architecture power management and control method based on an I2C bus. Thepower supply management and control method is implemented based on a power supply management and control device. The power supply management and control device comprises a control module, an execution module and an I2C bus. Compared with the prior art, the multiprocessor architecture power management and control method based on the I2C bus is designed mainly for a cabinet system composed of boardcards. The method adopts a distributed architecture and is composed of a control module board card and a plurality of same execution module board cards. The execution module board card uses a low-power-consumption processor A2F500 to receive a user instruction through an I2C bus and controls the power-on and power-off processes of high-power-consumption processors such as 6678 and Zynq in the board card. The problem that a traditional method cannot achieve control according to actual requirements is solved, and the purpose of actively controlling system power consumption through human factorsis achieved.

Description

Technical field [0001] The invention belongs to the technical field of cabinet system health management, and specifically relates to an I2C bus-based multi-processor architecture power supply management and control method. Background technique [0002] With the development of science and technology, electronic products have the development trend of miniaturization, integration, and modularization, and low power consumption indicators are particularly important. On the one hand, reducing system power consumption can reduce energy supply, making products smaller and adapting to miniaturized and integrated structures; on the other hand, each board can decide whether to run or not according to user needs, reducing the use of board cards Time can extend the service life of the board and meet the development trend of modularity. The traditional power management and control method is to monitor the temperature, input current, output voltage and other parameters to calculate the total p...
