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 in particular relates to an I2C bus-based multiprocessor architecture power management and control device. The power management and control device includes: a control module, an execution module, and an I2C bus; compared with the prior art, the present invention mainly designs a multi-processor architecture power management and control device based on the I2C bus for a cabinet system composed of boards and cards . The device adopts a distributed architecture and consists of a control module board and multiple identical execution module boards. The execution module board uses the low-power processor A2F500 to receive user instructions through the I2C bus, and controls the power-on and power-off process of high-power processors such as 6678 and Zynq in the board. It solves the problem that the traditional method cannot realize the control according to the actual demand, and achieves the purpose of actively controlling the power consumption of the system by human factors.

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...
