The invention discloses a multi-point monitoring alarm method and system. The method comprises the following steps that: a plurality of monitoring points are set in a monitored system, and wherein the monitoring points are respectively set at different levels, and the monitoring points of the same level monitor monitored objects in the corresponding level; alarm information fed back by the monitoring points in the monitored system is received; and duplicate removing processing is performed on the received alarm information; the alarm information which has been subjected to the duplicate removing processing is transmitted to users correlated with the monitored system. According to the multi-point monitoring alarm method and system provided by the technical schemes of the invention, the plurality of monitoring points are set in the monitored system, so that monitoring granularity can be refined; duplicate removing processing is performed on the alarm information, so that amplified and multifarious alarm information which are brought about by the refined monitoring granularity can be effectively simplified with no information lost; the alarm information which has been subjected to the duplicate removing processing is transmitted to the users, and therefore, the alarm information reading workload of the users can be greatly reduced, and the readability and warning performance of the alarm information can be improved, and the requirements of the users can be satisfied.
