Title: Gas detection device with multiple gas sensors and gas detection method
Inventor: TOYODA MASASHI
IPC: G01N27/12
Filed: 2020-01-30
Abstract: CONSTITUTION: A plurality of gas sensors each including a metal-oxide semiconductor whose value of resistance changes by contact with gas and a heater are used and operated with a supplementary circuit. The supplementary circuit counts an operation time of the gas sensors, and stores an initial value of a ratio of a value of resistance in the air to a value of resistance in an atmosphere containing detection target gas of predetermined concentration for each gas sensor. The supplementary circuit learns a value of resistance of the metal-oxide semiconductor in the air and detects gas when the value of resistance of the metal-oxide semiconductor is lower than a quotient of the learned value of resistance in the air and the initial value of the ratio. When a first gas sensor is operated for a predetermined time, the supplementary circuit operates both next gas sensor and first gas sensor during a learning period, continues detection of detection target gas with the first gas sensor, and learns a value of resistance of the metal-oxide semiconductor in the air with the next gas sensor. When the learning period ends, the detection target gas is detected with the next gas sensor.EFFECT: The life of the gas detection device is improved and the reliability of detection when the gas sensors are switched is maintained.SELECTED DRAWING: Figure 5
