Yuanzhong Shu, Tao Chenggong, Li Quan, Peng Xiaohong · 2009
In order to enhance the interoperability of device in EPA industry network control system, the characteristics of XDDL, the application flow and functions of EPA device description were discussed. The latest methods of XML parsing and the utilization efficiency of the device description data after being parsed were analyzed. A kind of parsing method and a double buffers technology used for device description data application were proposed. To evaluate the optimizing solution, the parsing methods were tested and compared. The test results indicated that the processing efficiency of EPA data parsing and application was improved. On the basis, the applying prospect of the optimizing solutions in CIMS and field device system was discussed.
