Abstract

Generally, in accordance with one embodiment, a monitoring system comprises a sensor, a wireless tag, a reader and a notification apparatus. The sensor is correspondingly arranged in a structure. The wireless tag is a passive wireless tag which is correspondingly arranged in the structure to send identification information and measurement information of the sensor by using received electromagnetic wave as a drive source. The reader communicates with the wireless tag to acquire the identification information and the measurement information. The notification apparatus acquires the identification information and the measurement information from the reader, detects a wireless tag or a structure serving as a notification target based on the identification information and the measurement information, and notifies the notification target.

First claim

What is claimed is:

1. A monitoring system of a social infrastructure, comprising:
a sensor configured to be arranged in the social infrastructure and detect one of a strain of the social infrastructure and a stress generated to the social infrastructure;
a passive wireless tag configured to be arranged in the social infrastructure to send identification information and measurement information of the sensor by using received electromagnetic waves as a drive source;
a reader which is installed in a vehicle and is configured to communicate with the wireless tag to acquire the identification information and the measurement information while the vehicle is operated;
wherein the sensor is configured to detect at least the stress generated to the social infrastructure and the social infrastructure comprises a tunnel, and wherein the stress sensor detects stress applied to an internal wall of the tunnel; and
a notification apparatus configured to acquire the identification information and the measurement information from the reader, detect the wireless tag or the social infrastructure serving as a notification target based on the identification information and the measurement information, and notify the notification target.

2. The monitoring system according to claim 1 , wherein the sensor is enabled to operate by the power generated by the wireless tag.

3. A monitoring method, including:
acquiring, using a reader which is installed in a vehicle, while the vehicle is operation, the identification information and the measurement information of a sensor from the a passive wireless tag which is arranged in a social infrastructure and is capable of communicating with the sensor arranged in the social infrastructure, wherein the sensor detects one of a strain of the social infrastructure and a stress generated to the social infrastructure;
detecting at least the stress generated to the social infrastructure and the social infrastructure comprises a tunnel, and wherein the stress sensor detects stress applied to an internal wall of the tunnel;
detecting the wireless tag or the social infrastructure serving as a notification target based on the identification information and the measurement information; and
notifying the notification target.
