AI Technical Summary
Technical Problem
Smoke detection modules in dormitories are prone to false alarms due to environmental interference such as dust, pollutants, and electromagnetic radiation, which compromises the safety and reliability of fire detection.
Method used
A dormitory detection device incorporating a smoke detection module and a carbon monoxide detection module, connected through an AND gate circuit, ensures that a fire is confirmed by simultaneous high-level signals from both modules before triggering an alarm, thereby reducing false alarms from environmental interference.
Benefits of technology
The device effectively distinguishes between genuine fire signals and environmental interference, ensuring timely fire detection and reducing false alarms, thereby enhancing fire safety in dormitories.

Abstract
The utility model provides a dormitory investigation detection device. The dormitory investigation detection device comprises a smoke detection module used for detecting a smoke signal; the carbon monoxide detection module is used for detecting carbon monoxide gas concentration; the first input end of the AND gate circuit is connected with the output end of the smoke detection module, the second input end of the AND gate circuit is connected with the output end of the carbon monoxide detection module, and the output end of the AND gate circuit is a fire detection signal output end. According to the invention, when dormitory safety reconnaissance is carried out, the false alarm probability of an existing smoke detection module can be reduced.
