Embodiment 1
[0066] Such as figure 1 As shown, the smoke detection device of this embodiment includes an optical labyrinth 1 , a signal acquisition chip 2 and a main control chip 3 .
[0067] The optical maze 1, the signal acquisition chip 2 and the main control chip 3 are electrically connected in sequence.
[0068] The signal acquisition chip 2 includes a timing control module 4 .
[0069] The optical labyrinth 1 includes a receiving tube 5 and a plurality of transmitting tubes 6 .
[0070] Among them, different launch tubes correspond to different working wavelengths;
[0071] Specifically, the emission tube 6 includes an infrared light emission tube, a blue light emission tube, a forward emission tube or a backward emission tube of the same wavelength, and the like.
[0072] Each transmitting tube 6 is electrically connected to the receiving tube 5 and the timing control module 4 respectively;
[0073] The timing control module 4 is used to time-sharingly drive different launch tub...
Embodiment 2
[0082] Such as figure 2 As shown, the smoke detection device of this embodiment is a further improvement to Embodiment 1, specifically:
[0083] The main control chip 3 is used to obtain the first environmental signal data corresponding to the shortest working wavelength;
[0084] The main control chip 3 is also used to calculate the set of intersections between the first environmental signal data and the second environmental signal data corresponding to other working wavelengths, and obtain the third environmental signal data;
[0085] Using the environmental signal data in the first environmental signal data except the third environmental signal data as the smoke signal data corresponding to the current environment.
[0086] Specifically, for the smoke signal data corresponding to the same working wavelength, the main control chip 3 is used to calculate the data rising rate according to the smoke signal data corresponding to different time points;
[0087] If the rising r...
Embodiment 3
[0120] The control method of the smoke detection device in this embodiment is realized by using the smoke detection device in any one of the embodiments 1 or 2.
[0121] Such as image 3 As shown, the control method of the smoke detection device of this embodiment includes:
[0122] S101. When the environmental impurities enter the optical maze, the receiving tube collects the environmental signal data of the current environment after the optical signal is scattered by the environmental impurities, and sends the environmental signal data to the main control chip through the timing control module;
[0123] S102. The main control chip analyzes the environmental signal data corresponding to different working wavelengths to obtain smoke signal data corresponding to the current environment, and determines whether to send an alarm signal according to the smoke signal data.
[0124] In this embodiment, environmental signal data corresponding to multiple wavelengths is collected in t...
