| Abstract: | In a measurement system,new representation methods are necessary to maintain the uncertainty and to supply more powerful ability for reasoning and transformation between numerical system and symbolic system.A grey measurement system is discussed from the point of view of intelligent sensors and incomplete information processing compared with a numerical and symbolized mea8urement system.The methods of grey representation and information processing are proposed for data collection and reasoning.As a case study,multi-ultrasonic sensor systems are demonstrated to verify the effectiveness of the proposed methods. |
