Abstract: A communication monitoring system includes a production data generation module, a data collection module, a data analysis module, and a data display module. The production data generation module generates production data representing a condition of production by a production device. The data collection module collects communication data representing a condition of communication on a network to which the production device is connected, and collects the production data. The data analysis module associates the communication data with the production data that are collected by the data collection module, in such a manner that the communication data is synchronized with the production data. The data display module performs a process for displaying the communication data and the production data that are associated with each other.

Abstract: A metal detector 20 includes a detection signal acquisition unit 31, a threshold value setting and updating unit 32, and a determination unit 33. The detection signal acquisition unit 31 acquires a detection signal that changes according to the detection strength for a rebar W1 contained in concrete W, on the surface of the concrete W. The threshold value setting and updating unit 32 sets a threshold value in order to determine the presence or absence of the rebar W1 on the basis of the maximum value and/or the minimum value included in the acquisition results for the detection signal acquired by the detection signal acquisition unit 31. The determination unit 33 determines the presence or absence of the rebar W1 by using the threshold value set in the threshold value setting and updating unit 32.
