Abstract
A smoke alarm system comprises a smoke alarm, a temperature detector, a first sampling circuit, a second sampling circuit and an analysis module; a first terminal of the first sampling circuit is connected to the smoke alarm, and a second terminal is connected to a first input terminal of the analysis module; the first sampling circuit is used for sampling from the smoke alarm to obtain a smoke sample value which is then output to the analysis module; a first terminal of the second sampling circuit is connected to the temperature detector, and a second terminal is connected to a second input terminal of the analysis module; the second sampling circuit is used for sampling from the temperature detector to obtain a temperature sample value which is then output to the analysis module; and the analysis module determines whether a smoke alarm signal is generated.
