Abstract
A compound detector for detecting smoke and temperature of a vehicle is disclosed. An inner seat is installed in an installation space and fixed with a pedestal. A controller is fixedly connected with the inner seat, a labyrinth smoke sensor including a labyrinth base, a labyrinth cover and a labyrinth structure between the labyrinth base and the labyrinth cover is arranged in an upper cover, a smoke sensing space is arranged in the center of the labyrinth structure, and a smoke sensing probe is arranged in the smoke sensing space. On-site air flow speed is reduced through the labyrinth structure to ensure normal use of a smoke detector, and the labyrinth structure adjusts and changes the wind-resisting capability to allow the detector to be adapted to different use environment. Smoke sensing compensation data can be obtained through self-learning of use environment by a temperature sensing detector, so that false alarm of the detector caused by dust and electromagnetic interference in the use environment can be eliminated, and more accurate and stable fire hazard monitoring is ensured.
