The sensing-aware environment of wisdom manufacturing workshop was built based on Cyber-Physical Systems， and all kinds of event models were defined. A synthetic data cleaning method based on SMURF was adopted to clean the raw RFID data. The complex event processing system was also applied to detect the abnormal conditions of workpieces， and a real-time status matrix was then formed. This system achieves the expected functions by simulation experiment， which provides a basis for proactive job-shop scheduling in wisdom manufacturing.
