A model transformation framework is presented which accept model transformation signals with ATLAS transformation language. When Platform Independent Model(PILVI) transform to Platform Specialize Model(PSM)，the signal sent by PILVI is judged by use of the ATLAS transformation language: if the signal belongs to the model transformation, the signal' s task would be executed; otherwise the feasible judgment would carzy on. If the signal is viable, it will return to the entrance waiting for the new signal,if not, the signal will be reported to the database and written in log.
