It is understood that the preset time may be a time period information set by the user, for example: 2h, etc., and this embodiment is not particularly limited thereto.
In a specific implementation, if the user detects 2 resistance changes in the gas detection unit within 2h, that is, it indicates that there are two exhausts within 2h, and the exhaust frequency is 1 and 1 h.
It is to be understood that since the change in the resistance is caused by the reaction of the methane gas contained in the gas with the nano tin dioxide in the gas detection sensor in the present embodiment, the higher the exhaust gas concentration, the longer the reaction time, the larger the resistance change, and accordingly, the smaller the resistance change, the shorter the reaction time, and the lower the exhaust gas concentration.
The embodiment discloses that if a resistance change difference exists, whether a gas signal acquired by a gas sensor is an exhaust signal is judged according to the resistance change difference; if so, performing data analysis on the resistance change difference value to obtain exhaust detection data.
