Problems solved by technology

However, the coverage rate for special public areas such as communities, high-rise buildings, and small entertainment venues is not high, and the equipment is outdated and the sensitivity is not high. Real-time networking cannot be realized, which brings delays to the information acquisition speed of the fire center and reduces the response sensitivity. Once a fire breaks out, it will have devastating consequences

Embodiment

[0025] figure 1 It is a schematic diagram of the alarm module, including STM32F103ZET6 CPU, temperature sensor, smoke sensor, carbon monoxide sensor, radar sensor, China Mobile M5310-A ​​IoT module. China Mobile's M5310-A ​​IoT module integrates the NB-IoT module. The data collected by each sensor is analyzed and processed by the central processor, and then the NB-IoT module uploads the alarm data to the OneNET cloud platform.

[0026] Such as figure 2 As shown, the NB-IoT module uses the LwM2M protocol to connect to the OneNET cloud platform to realize data networking.

[0027] Each M5310-A ​​module has a corresponding IMEI and IMSI number segment, log in to the OneNET platform to register the module, create a device according to the product field to which the alarm belongs, specify the communication protocol of the device, and enter the IMEI and IMSI The platform can assign a Device ID to the device, and the device ID can be used for data reading by third-party applicatio...

Abstract

The invention discloses a multi-functional fire alarm and alarm method based on narrow band Internet of things (NB-IoT). The alarm comprises a central processing unit, a temperature sensor, a smoke sensor, a carbon monoxide sensor, a radar sensor and an Internet of things module, wherein the temperature sensor, the smoke sensor, the carbon monoxide sensor, the radar sensor and the Internet of things module are connected with the central processing unit respectively; an NB-IoT module is integrated in the Internet of things module; data collected by the sensors are analyzed and processed by thecentral processing unit; and then the NB-IoT module uploads alarm data to a OneNET cloud platform. Through the adoption of the multi-functional fire alarm and alarm method, multi-node networking can be realized; environment data are successfully uploaded to the cloud; and the aim of remote monitoring is fulfilled.

Description

technical field [0001] The invention relates to smart community management, specifically a multifunctional fire alarm based on the narrowband Internet of Things, which belongs to the technical field of Internet of Things applications. Background technique [0002] Since the 21st century, the era of the Internet of Things is affecting and changing our living habits, methods, rhythm and quality of life at an unprecedented speed. The smart life concept of "Internet of Things +" has gradually entered people's lives. In terms of living, people's housing needs are not limited to being able to shelter from wind and rain, and to resist wind and cold, but are pursuing an ideal goal of pursuing an information-based and safe living environment for their housing. Firefighting work is the basic guarantee for people's better life and property safety. In recent years, the total number of fire hazards has been increasing year by year. Traditional and non-traditional fire safety hazards are...
