In order to better use the the advantages of RFID to col ect manufacturing workshop data, make a minimal impact on the enterprise application system, so the enterprise need not re-develop and deploy this system, The RFID middleware for col ecting manufacturing plant data is studied. The RFID middleware adopts the distributed structure in improving efficiency, saving time and re-ducing cost. At the same time the protection of manufacturing information is put forward. It meets the requirements of keeping the im-portant manufacturing information secret of the enterprise.%为了更好的利用RFID的优点采集制造车间的数据，并对企业应用系统的影响最小，企业不需要重新开发部署应用系统，对应用于采集制造车间数据的RFID中间件进行了研究， RFID中间件采用了分布式的结构，达到了提高效率、节省时间和降低成本的目的，同时提出了对制造信息的保护，满足了企业对重要制造信息保密的要求。
