Old building safety supervision and early warning device based on NB-LOT network

Abstract

The invention belongs to the technical field of old building safety supervision and early warning systems, and particularly relates to an old building safety supervision and early warning device basedon an NB-LOT network, which comprises a wireless NB-LOT inclination angle sensor terminal, a wireless NB-LOT vibration sensor terminal, a cloud data center and a safety supervision and early warningsystem. The wireless NB-LOT inclination angle sensor terminal comprises an ARM processor, and a chip SCA103T realizes a function assembly, a memory, an NB-LOT communication module and a power supply assembly based on an MEMS. The wireless NB-LOT vibration sensor terminal comprises a detection unit MEMS micro-accelerometer, a micro-processing unit, a wireless transmission unit NB-LOT communicationmodule and a power unit. The old building safety supervision and early warning system based on the NB-LOT network has the advantages of being low in power consumption and cost, stable in network, reliable in work, real in data, high in stability, capable of achieving safety supervision of old buildings and capable of conducting early warning on the old buildings when necessary.

Description

technical field [0001] The invention relates to the technical field of an old building safety supervision and early warning system, in particular to an old building safety supervision and early warning device based on an NB-LOT network. Background technique [0002] Housing security is directly related to the basic life, life and property safety of the people. With the aging of urban infrastructure such as buildings in our country, and due to historical reasons, the level of house structure design and construction quality are uneven; and the aging of the house itself and the natural and man-made damage that may be suffered during use, such as earthquakes Natural disasters such as hurricanes, typhoons, illegal demolition, or other factors may reduce the safety of historical buildings and dilapidated buildings year by year, and even irreversible emergencies may occur. Old buildings have turned into dilapidated buildings and even collapsed, causing very serious consequences. ...

Problems solved by technology

With the aging of urban infrastructure such as buildings in our country, and due to historical reasons, the level of house structure design and construction quality are uneven; and the aging of the house itself and the natural and man-made damage that may be suffered during use, such as earthquakes Natural disasters such as hurricanes, typhoons, illegal demolition, or other factors may reduce the safety of historical buildings and dilapidated buildings year by year, and even cause irreversible emergencies

Old buildings turned into dangerous buildings, or even collapsed, causing very serious consequences

[0003] At present, the detection of old buildings is basically blank, and the problems of old buildings are all observed daily. Because there is no long-term real-time monitoring system, the change trend of old buildings cannot be monitored in real time before they collapse or before they collapse, resulting in Evolve into a dilapidated building, suddenly collapse or collapse, causing heavy losses to people's lives and properties

[0004] The traditional monitoring system has the disadvantages of high cost, cumbersome installation, unstable network, high maintenance and update costs, etc., and cannot monitor the structural changes of old buildings well
