Gas alarm replacement warning method and device, and electronic apparatus including the device

A gas alarm replacement warning device, comprising:

• a collection module, configured to acquire signal data of the gas alarm;
• an analysis module, configured to analyze a current use state of the gas alarm based on the signal data;
• a determination module, configured to determine a dynamic model of an expected service life of the gas alarm according to the current use state, and calculate an expected use duration of the gas alarm;
• a judgment module, configured to judge whether an actual use duration of the gas alarm is greater than or equal to the expected use duration;
• and
• an output module, configured to output a replacement prompt signal when the judgment module outputs a judgment that the actual use duration of the gas alarm is greater than or equal to the expected use duration, wherein:
• the determination module is configured to determine the dynamic model of the expected service life of the gas alarm according to the current use state by a process comprising:
• determining a plurality of weighting factors that affect an actual service life of the gas alarm according to the current use state;
• and
• dynamically adjusting a basic model of the expected use duration of the gas alarm according to the plurality of determined weighting factors, to obtain the dynamic model;
• the determination module is configured to dynamically adjust the basic model of the expected use duration of the gas alarm according to the plurality of determined weighting factors to obtain the dynamic model by a process comprising:
• comparing the plurality of determined weighting factors with at least one weighting factor in the basic model, wherein when one or more of the at least one weighting factor in the basic model is not in the plurality of determined weighting factors, the one or more of the at least one weighting factor in the basic model has a value of 1;
• and
• the basic model is L=L0*E1*E2* . . . *En, where L is the expected use duration of the gas alarm, L0 is a reference use duration of the gas-sensitive element, E1*E2* . . . *En represents the at least one weighting factor, and n is a natural number.
