LoRaWAN based fire hazard detection linked alarming system and method

Abstract

The invention discloses a LoRaWAN based fire hazard detection linked alarming system and method, and belongs to the technical field of the Internet of Things. The system comprises wireless linked firehazard detection alarms, LoRaWAN gateways, a network management server, an application management serve, a linked alarming server and a management terminal. Technical problems in realizing linked detection of adjacent fire hazard detectors and simultaneous linked alarming in adjacent spaces are solved. Adjacent alarms realize automatic linked alarminig to replace a single-alarm alarming manner, when alarming is triggered due to fire hazard in certain place, alarms in the adjacent areas emit local acousto-optic alarming at the same time, people in the neighbor areas can be notified to escape timely, and defects of present local alarming and wireless mobile phone alarming can be overcome; different algorithms are used for reckoning, and the alarms in the neighbor range are associated automatically according to the fire hazard damage radius; and power is supplied to batteries of the alarms for long term on the basis of low-power wide-area technology of LoRaWAN.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, and in particular relates to a LoRaWAN-based fire detection linkage alarm system and a method thereof. Background technique [0002] With the acceleration of urbanization, the number of fire hazards is increasing, people's awareness of fire protection is gradually improving, and the installation of fire detection and alarms has been popularized to a certain extent, which has played a role in fire prevention and disaster reduction. In order to effectively prevent and contain severe and extraordinarily large fires, especially mass casualties and casualties, the fire department requires the promotion and installation of independent fire detection alarms or wireless fire detection alarms in some places that are not suitable for installing wired fire detection alarms, such as schools. Dormitories, rental houses, residential buildings and other crowded places have played a role in preven...

Problems solved by technology

In order to effectively prevent and contain severe and extraordinarily large fires, especially mass casualties and casualties, the fire department requires the installation of independent fire detection alarms or wireless fire detection alarms in some places that are not suitable for installing wired fire detection alarms, such as schools. Dormitories, rental houses, residential buildings and other crowded places have played a role in preventing fires, but the above-mentioned alarms still have some defects and deficiencies. The independent detection alarm can only provide local sound and light alarm prompts to achieve point-to-point detection in a single space Call the police, the alarm message will not be received if the person is not on the scene

The wireless fire detection alarm adopts NB-IoT or LoRa technology, and at the same time as the local sound and light alarm, the alarm information is sent to the computer or mobile phone through the network. The alarm method adopts telephone, SMS, WeChat, etc., and the alarm information can be pushed to the relevant personnel , take measures in time, the disadvantage is that you must carry your computer or mobile phone at all times, and there will also be cases of missed receipts and alarms due to failure to check in time

Both of the above two methods have great limitations. When a fire occurs, the alarm information cannot be effectively sent to the neighbors at the fire point in time, and the adjacent personnel cannot be notified in time to evacuate. Loss
