Title:
GAS DETECTION METHOD, PROGRAM, CONTROL SYSTEM, AND GAS DETECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/158424
Kind Code:
A1
Abstract:
The purpose of the present disclosure is to suppress degradation of a filter part. This gas detection method comprises a first process, a second process, and a third process. In the first to third processes, the pathway for gas is switched among first to third pathways. The first pathway is a pathway that sequentially passes through first passage parts (31, 41), a sensor chamber (100), and second passage parts (32, 42). The second pathway is a pathway that sequentially passes through a sample gas supply route (R1) not passing through a filter part (20), and a sensor chamber (100), and that causes gas to be discharged from the sensor chamber (100) without passing through the filter part (20). The third pathway is a pathway that sequentially passes through the first passage parts (31, 41) and the sensor chamber (100), and that causes gas to be discharged from the sensor chamber (100) without passing through the filter part (20).
