NB-IoT-based object overturn early warning system

Abstract

The invention discloses an NB-IoT-based object overturn early warning system comprising multiple detectors, a cloud server and multiple early warning terminals. Each detector is provided with a shellused for being fixed on the measured object, a PCB arranged in the shell and a monitoring circuit arranged on the PCB. The monitoring circuit is provided with an MEMS inertial sensor module which is fixed on the central position of the PCB and used for sensing the six-degree-of-freedom parameters of the space motion of the measured object in real time, an AM2302 environmental temperature and humidity monitoring sensor module which is used for sensing the surrounding environmental temperature and humidity parameters of the measured object, an NB-IoT data module which is used for transmitting the degree-of-freedom parameters and the environmental temperature and humidity parameters and a 32-bit low-power-consumption STM32F103C single-chip microcomputer which is used for preprocessing the degree-of-freedom parameters and the environmental temperature and humidity parameters. The cloud server and the detectors form wide area internet of things communication connection through a wide area internet of things NB-IoT base station for transmitting early warning signals. Multiple early warning terminals are connected with the cloud server in a communication way through the wide area internetof things and used for receiving the early warning signals.

Description

technical field [0001] The invention belongs to the field of precision instruments for the Internet of Things, and in particular relates to an NB-IoT-based object overturning early warning system. Background technique [0002] In people's daily life and production practice, it is necessary to measure and warn the movement posture of sensitive equipment in many scenarios, such as: the overturning of large billboards, the tilting of the working arms of large construction machinery such as bridge cranes, and the inclination of high-voltage transmission towers Inclination, tilt angle monitoring of micro-buildings, abnormal acceleration monitoring of elevators, abnormal movement monitoring of important asset equipment (such as safes), etc. In the above situations, it is necessary to accurately measure the spatial motion posture of the monitoring object, and if it exceeds the safety threshold, it needs to call the police in time; or it needs long-term monitoring to grasp its motio...

AI Technical Summary

Problems solved by technology

As far as the related documents are concerned, there are existing instruments and equipment on the market that carry out remote monitoring of the motion posture of the above-mentioned equipment, but most of them have a prominent problem of adopting data transmission means such as GPRS / 3G / 4G, and the power consumption of the detector 1 is relatively low. Large, unable to use battery power for long-term field work, and the operation and maintenance costs are relatively large
