More Information
Summary:The invention discloses a smoke particle recognition method and system based on temperature compensation and a vehicle. The method comprises the steps of: controlling the on/off of a first light-emitting unit and a second light-emitting unit based on a preset sampling rule, and obtaining an environment temperature parameter, a first light wave response parameter and a second light wave response parameter in a sampling period; determining a response intensity ratio parameter according to the first light wave response parameter and the second light wave response parameter; performing data compensation on the first light wave response parameter and the second light wave response parameter according to the environment temperature parameter, and determining a real-time smoke value; determininga smoke type and a smoke alarm threshold according to the response intensity ratio parameter; and acquiring a current smoke background value, and determining a smoke alarm state according to the real-time smoke value, the smo
