Embodiment Construction

[0034] The basic idea of ​​the present invention is to establish a mapping relationship between the slot address of the source fan board and the slot address of the associated fan board through the associated fan mapping table, and use the state acquisition module and the state processing module to obtain the state of the associated fan board. When the status of the fan board is abnormal, the associated fan processing module sends a speed adjustment command to the fan speed automatic control module of the source fan board according to the fan speed control policy in the fan speed control policy table to adjust the speed of all fans on the source fan board. , so as to realize the associated control of the fan speed among multiple fan boards, improve the heat dissipation efficiency and reliability of the product, and prolong the operating life of the fan.

[0035] The present invention provides an associated fan speed control device, such as figure 2 As shown, the SHMC includes...

Abstract

The present invention discloses a device and a method for association fan rotating speed control. A mapping relation is set up between a source slot address and an association slot address by an associating fan mapping table. The state of an association fan plate is obtained from a state processing module to a state acquisition module. When the association fan plate appears an abnormity, an association fan processing module emits a rotating speed adjusting command to a fan rotating speed automatic control module of a source fan plate in dependence on fan rotating speed control strategy in a fan rotating speed control strategy table and the fan rotational speed automatic control module adjusts rotating speed of each fan on the module fan plate. Thus the association control of the fan rotating speed among a plurality of association fan plates can be achieved. The association fan rotating speed control improves heat radiation efficiency and reliability of a product, lengthens fan operation lifetime, realizes a dynamic configuration of the association fan mapping table and the fan rotating speed control strategy table, increases flexibility of a product, and ensures manageability of ATCA.

Description

technical field [0001] The present invention relates to Advanced Telecommunication Computing Architecture (ATCA, Advanced Telecommunication Computing Architecture), in particular to a device and method for controlling the speed of an associated fan in ATCA. Background technique [0002] ATCA is a telecommunications platform designed by telecommunications experts for telecommunications applications, mainly to solve system bandwidth issues, high availability issues, field upgrade issues, scalability issues, manageability issues, and interoperability issues that telecommunications systems currently face . [0003] It has become a trend for communication products to adopt ATCA. At present, the IPMI (Intelligent Platform Management Interface) specification is mainly used to configure the required monitoring parameters, monitor the temperature and voltage of each single board inside the product, and the temperature and speed of the fan. , coordinate the power distribution of each...
