## Abstract

A maintenance method of intelligent ODN management system comprises the following steps: carrying out mutual exclusion protection on a same operation task, wherein each executable operation task is protected by operation authorization, and any one maintenance and management terminal needs to acquire the operation authorization of the operation task before executing the operation task and release the corresponding operation authorization after the execution is finished; and carrying out mutual exclusion protection on different maintenance and management terminals, wherein after a local maintenance center obtains control right on the intelligent ODN management system, a remote maintenance center and a local maintenance terminal need to apply for authorization from the local maintenance center before operating the intelligent ODN management system, and can deliver an operation instruction after successfully applying for the authorization. A system exception caused by conflicted operations is therefor effectively prevented.
