Specific embodiment
Below in conjunction with the attached drawing of the utility model, the technical solution of the utility model embodiment is carried out clear, complete
Description.
A kind of revealed wireless smoke detector of the utility model using NB-IOT modules, realizes that smoke detector is accused
Low power consumption transmission, the transmission coverage area of alert information are remote and other effects.
With reference to shown in Fig. 1 and Fig. 2, a kind of revealed wireless smoke detector of the utility model acquires single including data
Member, data processing and transmission unit, Power Management Unit and antenna, wherein, data acquisition unit and data processing and transmission are single
Member is connected, and sends collected smog information to data processing and transmission unit and wakes up data processing and transmission unit,
Data processing and transmission unit when detecting smoke alarm, generate warning information and by warning information by NB-IOT modules without
Line is launched.
Specifically, data acquisition unit includes smoke sensor device and the Smoke Detection unit being connected with smoke sensor device, cigarette
The smog information detected, if detecting smog, is transferred to Smoke Detection unit by mist sensor for detecting smog information；
After the smog information received is carried out analog to digital conversion (A/D transformation) by Smoke Detection unit, data processing is actively sent interrupts to
With transmission unit and wake up data processing and transmission unit.
Data processing and transmission unit include data processing unit and NB-IOT modules, data processing unit and Smoke Detection
Unit is connected, and NB-IOT modules are connected with data processing unit, antenna.Data processing unit is in the smog letter for judging to receive
When breath is more than its preset smog alarm thresholding, generates warning information and emit warning information from antenna by NB-IOT modules
It goes out.Specifically, data processing unit is within the preset time, if not detecting smog information, enters sleep state,
Purpose is to reduce power consumption.And enable RTC (Real-Time Clock, real-time clock) before sleep state is entered and wake up, work as RTC
Timing time-out then sends interruption (when judging that the smog information received is more than its preset smog alarm thresholding) and wakes up data
Processing unit.In the present embodiment, data processing unit, which receives, interrupts and is detected after waking up whether its interruption I/O pin is high level,
