Perception machine perceives environment, dragoman’s behavior rules are recorded in domain-knowledge database, and based on which reasoning machine performs behavior reasoning. The paper introduces the concept, the principle and the structure of perception machine, domain knowledge database and reasoning machine; and the method’s application in “Real-time roaming system of the ancient San He town” is also shown.
