Adetecting system based on emulated environment is designedto address the issue of lacking of real world diversity simulation approaches in today’s identification capability evaluation procedure for non intrusive terminal. With the basis of application scenario of non intrusive terminals and core identification function testing requirements

overall design is implemented regarding of hardware environment

software function and testing methodology. By using generic investigation approach

the rules of apparatus application is analyzed and testing case library as well as testing scenario collectionsare established. The objectiveness and reasonableness of the testing scenario is improved by employing the optimized testing procedure based on stochastic sampling and partical swarm optimization. At last

the conclusions are applied and verified by the non intrusive terminal platform construction in demand side management technical lab of Jiangsu Province.The results show that the system can improve the scientificity

objectivity and economy of the test scheme

and meet the requirements of non invasive terminal batch test.
