In diagnosis center, we introduced the work model of uniting intelligent diagnosis with expert diagnosis, made use of the association rule to mine the knowledge and used it for intelligent diagnosis. This paper illustrated the network framework of the system, the knowledge mining arithmetic based on association rule, appraisal and implementation.
