The invention provides a mass data processing system, equipment and method based on association rule extraction. The system comprises an association rule information extraction device, an association parameter information record list storage device, a data processing server, a first database, a second database and a parameter list storage device, the association rule information extraction device reads the data record of the current period from the first database periodically, and the statistic analysis operation is executed based on the read data record of the current period, a plurality of parameter lists and the association rules among the parameter lists to obtain an association parameter information record list. The mass data processing system, equipment and method based on the association rule extraction can enable the number of the recorded parameter lists to be small, and the system can have high parameter analysis performance.
