Abstract:In order to improve the intelligence of smart city lighting monitoring system, the association rules are used to mine the intrinsic connection among control commands. Considering that the traditional Apriori algorithm uses a self-connected method to generate a large number of candidate sets, the execution efficiency is low, so the improved Apriori algorithm is adopted. The frequent set is generated by traversing the weighted graph form, the algorithm execution efficiency is improved, and the control mode association rule is generated. The application of the rule and the control module of the smart city lighting monitoring system realizes the intelligent association of the control mode, reduces the dependence of the system on the management personnel experience, improves the work efficiency, and has certain social application and promotion value.
