Embodiment 1

[0025] The smoke detection device based on the NB-IOT technology of the present invention includes a main control unit, a photoelectric smoke sensing unit, a buzzer alarm unit, an NB-IOT communication unit, a power supply unit, and a cloud platform.

[0026] The photoelectric smoke sensing unit is used to detect smoke, and the detection result is output to the main control unit in the form of a voltage signal; the main control unit is used to control the buzzer by outputting a signal of a certain frequency in response to the voltage signal of the photoelectric smoke sensing unit Make a sound and output the smoke alarm information to the NB-IOT communication unit, and the NB-IOT communication unit is used to forward the smoke alarm information to the cloud platform; the cloud platform is used to respond to the smoke alarm information and display the device as a smoke alarm state.

[0027] The main control unit also includes a start button, a button detection unit, and a bootload...

Embodiment 2

[0036] Such as figure 1 As shown, the present invention also provides a smoke detection method based on NB-IOT technology, the method includes:

[0037] Step S1: Power on the device;

[0038] Step S2: the photoelectric smoke sensing unit detects smoke, and converts the detection result into a voltage signal;

[0039] Step S3: The main control unit responds to the voltage signal, controls the buzzer to sound by outputting a signal of a certain frequency, and outputs the smoke alarm information to the NB-IOT communication unit;

[0040] Step S4: The NB-IOT communication unit forwards the smoke alarm information to the cloud platform; the cloud platform responds to the smoke alarm information and displays the device as a smoke alarm state.

[0041] Wherein, after step S1 and before step S2, step S5 is also included: detecting whether the time of pressing the button exceeds a preset value, if the time of pressing the button is greater than a preset value, then based on the user'...

Abstract

The invention discloses a smoke detecting device based on the NB-IOT technology. A control unit is adopted to periodically perform self-detection on a smoke sensor and the battery power, smoke alarm information, smoke sensor status information, and device battery power information are uploaded to a cloud server through a NB-IOT communication unit and managed by a cloud platform, and a smoke alarmsystem integrated with the smoke alarm and the device self-detection is realized. At the same time, the device is periodically woken up by configuring an RTC alarm clock, the device is in a low powermode when the device is not woken up, and the power consumption of the smoke alarm device is effectively reduced.

Description

technical field [0001] The invention relates to the field of alarm equipment, in particular to a smoke detection device and method based on NB-IOT technology. Background technique [0002] Existing smoke detection devices generally adopt a distributed offline working mode. When a fire occurs, only a buzzer alarm is generated at the fire scene, lacking unified management and monitoring, which is not conducive to safe monitoring, especially for some large-scale public buildings ; At the same time, the smoke detection device is released offline in the building, and it can only be manually inspected regularly, and the period of regular inspection is usually relatively long, and due to the instability of personnel operations, it cannot be guaranteed that the inspection work will be carried out regularly according to the specified cycle Execution, resulting in failure to check in time after the abnormality of the smoke detection device, posing a safety hazard.
