<p>PROBLEM TO BE SOLVED: To achieve a gas detection system capable of freely installing a gas detection device, and confirming the leakage position of gas at a management device side on the basis of the gas detection signal of the gas detection device without making it necessary to grasp an installation place in advance at the management device side.SOLUTION: A gas sensor 2 includes position information acquisition means 21 capable of acquiring its own position information i, which is configured to acquire the position information i when detection target gas is detected, and to transmit the position information i and a detection signal S to a management device 3. The management device 3 includes: gas leakage position information storage means 31 for storing gas leakage position information X as the position information of a place where gas leakage tends to occur in a monitoring target area; and gas leakage position estimation means 32 for, when receiving the detection signal S from the gas sensor 2, estimating a place Xe where gas leakage occurs on the basis of the position information i received as well and the gas leakage position information X.</p> |
