Abstract

Provided is a carbon dioxide ground leakage monitoring system that is low cost, capable of real-time multi-point monitoring on a wide scale, and capable of providing the public with easy-to-understand information.

A plurality of monitoring posts 100 and a field data server 200 and the field data server 200 and an administrative server 300 are connected by communication lines in respective sections therebetween. The plurality of monitoring posts 100 measure a concentration of carbon dioxide having leaked above the ground, and transmits the measured carbon dioxide data to the field data server 200, the field data server 200 transmits the data transmitted from the plurality of monitoring posts 100 to the administrative server 300, and the administrative server 300 discloses carbon dioxide ground leakage information on the Internet based on the carbon dioxide data transmitted from the field data server 200.

Claims

1. A carbon dioxide ground leakage monitoring system including a plurality of monitoring posts, a field data server, and an administrative server, wherein

the plurality of monitoring posts and the field data server and the field data server and the administrative server are connected by communication lines in respective sections therebetween,

the plurality of monitoring posts measure a concentration of carbon dioxide having leaked above the ground, and transmits the measured carbon dioxide data to the field data server,

the field data server transmits the data transmitted from the plurality of monitoring posts to the administrative server, and

the administrative server discloses carbon dioxide ground leakage information on the Internet based on the carbon dioxide data transmitted from the field data server.

2. The carbon dioxide ground leakage monitoring system according to claim 1, wherein the communication lines that connect the plurality of monitoring posts and the field data server are a mesh-type wireless communication network having the plurality of monitoring posts as nodes.

3. The carbon dioxide ground leakage monitoring system according to claim 1, wherein the plurality of monitoring posts measure a concentration of carbon dioxide having leaked above the ground by an interval operation.

4. The carbon dioxide ground leakage monitoring system according to claim 3, wherein the plurality of monitoring posts monitor a remaining charge level of a battery equipped therein, and change the interval operation in cycle according to the remaining charge level of the battery.

5. The carbon dioxide ground leakage monitoring system according to claim 3, wherein the field data server instructs the plurality of monitoring posts to change the interval operation in cycle.

6. The carbon dioxide ground leakage monitoring system according to claim 1, wherein a carbon dioxide concentration measurement section of the plurality of monitoring posts is composed of a retention chamber, a carbon dioxide concentration measuring sensor, and a protective cover,
