With the rapid development of the Internet of things, smart home based on Internet of things has gradually entered into family life of people. The user can accord to the requirement for personalized and customized service life. However, smart home systems appear conflicts between rules frequently, because the number of rules is becoming more and more. Therefore, this paper proposes EasiRCC, a new-type method of rapid rule-matching and conflict resolution. Resolving the conflict problem mainly focuses on rule-matching and conflict resolution. Firstly, for the problem of rule-matching, because repeating matching takes place in the existing methods frequently, we propose an algorithm named EasiRMA, which is used to fast match rule based on Hash function and raise the efficiency of rule-matching. Secondly, for the problem of conflict resolution, we come up with a scheduling mechanism of mixed-priority, which the system can adaptively adjust priority of rules, and resolve rule-conflict in time. Experimental results show that EasiRCCs efficiency of rule-matching is not changing as the number of rules is increased, and its running time is constant, but the running time of traditional matching method is O(N), and EasiRCC can effectively resolve conflict in the condition that does not affect users normal household lives.
