Structural health monitoring is a noticeable technology for aged civil structures, buildings, chemical or nuclear plants. Although it carries out various existence as the technique of supervising generating development of the damage in the structure, when diagnosing damage, a sensor is indispensable near the damage part. Therefore performing the health monitoring of large-sized structure has many problems in respect of the number of the sensors and expense. As dissolution of such a problem, the present study proposes Ethernet LAN technologies for the sensor integration technology. The present study deals monitoring of deformation of pipes using change of natural frequencies judged by the statistical tools such as Response Surface and F-Statistics.
