Fan monitoring method and system in multi-field equipment and fan plug-in box

Abstract

The invention discloses a fan monitoring method in a multi-field equipment, which comprises: (a) a centralized monitoring device sends command to a specified fan through a RS485 bus; (b) according to the received monitoring command, a fan plug box which the specified fan belongs to monitors the specified fan. The invention also discloses a fan monitoring system in a multi-field equipment and a fan plug box. Compared with the prior art, the invention has the advantages that: being able to monitor all fans in the equipment, accurately positioning quantity and position of fault fans; through single RS485 interface, the centralized monitoring device monitors states of all fans, the interface is simple and convenient to be realized, the system source is saved; the expansion is convenient, whenmonitoring fan plug box is required to be added, only hitching the additional fan plug box on the RS485 bus is okay; the monitoring capacity and efficiency are high, the realization method is relatively simple; state controlling of all fans in the access network equipment can also be simply realized.

Description

Method and system for fan monitoring in multi-field equipment, and fan sub-box technical field The invention relates to a fan monitoring method and system, in particular to a fan monitoring method and system in multi-field equipment based on RS485 bus. Background technique In multi-field equipment, especially access network equipment, the Optical Network Unit (ONU) will generate and accumulate a large amount of heat during operation. If the heat is not dissipated in time, it may cause the ONU equipment to work in the long-term A higher temperature will inevitably bring about many problems such as unstable operation of the equipment. If the working environment of the ONU equipment itself is a high-temperature environment, the heat inside the equipment will not be dissipated in time, and the impact will be more obvious. Usually, the ONU device is installed in a relatively remote location, and the environment of the computer room is relatively harsh, so how to effectively sol...
