Embodiment Construction

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

[0030] The cabinet is composed of various boards. The present invention aims to adopt a strategy: the control module of the cabinet is used 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: one processor receives the user's instruction information through I2C, and controls the power-on and power-off of other processors, thereby realizing flexible power control functions.

[0031] In order to solve the problems of the prior art, the present invention provides a multi-processor architecture power management and control device based on I2C bus, such as figure 1 As shown, th...

Abstract

The invention belongs to the technical field of cabinet system health management, and particularly relates to a multiprocessor architecture power management and control device based on an I2C bus. Thepower 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 device based on the I2C bus is designed mainly for a cabinet system composed of board cards. The device adopts a distributed architecture and is composed of a control module board card and a plurality of sameexecution 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 factors is achieved.

Description

technical field [0001] The invention belongs to the technical field of cabinet system health management, and in particular relates to an I2C bus-based multiprocessor architecture power management and control device. Background technique [0002] With the development of science and technology, electronic products have a trend of miniaturization, integration, and modularization, and low power consumption indicators are particularly important. On the one hand, reducing the power consumption of the system can reduce the energy supply, so that the product can be made smaller and adapt to the structure of miniaturization and integration; Time can extend the service life of the board and meet the development trend of modularization. The traditional power control method is to monitor the temperature, input current, output voltage and other parameters to calculate the total power consumption of the system, and to control the total power consumption of the system below the set thresh...
