Network sensor is a new sensing technique in which sensor signal is transferred into digital signal and transmitted on the basis of network protocol. The network sensor provides for the consolidation of analog signal conditioning and digital signal processing functions at the sensor, which results in system cost reductions, high reliability and improved performance. In order to improve the disadvantage of the traditional structure safety monitoring system, the principle and realization of a novel network sensor designed with A/D converter ADS8321, microprocessor Rabbit3000 and TCP/IP protocol are introduced. The structure health monitoring system (SHMS) based on network technique is discussed as well. The results show that the network sensor has the characteristics of great applicability, flexibility and high reliability. It represents the new development direction of the structure health monitoring system
