Abstract: An information collection system includes a server apparatus, a plurality of edge apparatuses, and a collection rules storage unit. The edge apparatus includes a first information generation unit that generates first information and a second information generation unit that generates second information. The collection rules storage unit stores collection rules so as to be associated with the edge apparatus and the first information that the server apparatus acquires from the edge apparatus. The server apparatus includes a first information acquisition unit that acquires the first information from the edge apparatus, a second information acquisition unit that acquires the second information from the edge apparatus, and a collection rules acquisition unit that acquires collection rules from the collection rules storage unit.

Abstract: Degradation of a pipe can be easily detected. A piping inspection system 1 includes an excitation unit 100, a wave detection unit 210, and a diagnosis unit 220. The excitation unit 100 excites waves of different wave modes simultaneously at a first position of a pipe 300. The wave detection unit 210 detects the waves of different wave modes at a second position of the pipe 300. The diagnosis unit 220 diagnoses degradation of the pipe 300 based on a velocity of one of the waves of different wave modes, the velocity being calculated by using a detection time difference between the waves of different wave modes.
