The invention discloses a multi-sensor data source processing method and device. The method comprises the following steps: monitoring and reading dynamic data collected by each sensor in real time; matching the dynamic data with a set simple event generation rule, if the matching is successful, sending a starting signal and generating simple events; reading the simple events, generating a simple event set, and filtering the simple event set according to a set event filtering rule; and carrying out aggregation on the simple event set obtained after filtering according to a set event aggregation rule, and generating a complex event. The multi-sensor data source processing method and device can carry out timely processing on a multi-data source. Through generating the simple events, then, generating the simple event set, carrying out filtering and aggregation on the simple event set, and finally, generating the complex event containing more data information, the method and the device can effectively support real-time flow service flow monitoring; the processing performance is high; and the flexibility is high.
