Important object state monitoring unit based on NB-IoT and monitoring method thereof

Abstract

The invention provides an important object state monitoring unit based on NB-IoT, a sensing detection unit, Internet of things cloud equipment and a monitoring system. According to the monitoring method, real-time environment information is uploaded periodically, and whether an important object is under threat or not is judged according to monitoring preset parameters, wherein an uploading periodand the monitoring preset parameters are preset, and real-time update is supported. Through adoption of the monitoring method, flexible coping can be implemented according to specific situations, andfalse alarm is reduced. Moreover, the monitoring method also provides a static monitoring function, s dynamic monitoring function, a forcible entry prevention monitoring function, a data analyzing function and a diagram outputting function, has high applicability, and is convenient to use. The invention also provides a sensing detection unit for executing the monitoring method, Internet of thingsequipment and a monitoring system.

Description

technical field [0001] The invention belongs to the field of IoT (Internet Of Things), and in particular relates to an NB-IoT-based important item status monitoring unit and a monitoring method thereof. Background technique [0002] With the rapid development of my country's Internet of Things technology, sensor technology, and chip technology, many needs that could not be realized have become possible. In various fields such as the army, customs, public security, finance, mining, chemical industry, storage, and family There are static and dynamic monitoring problems of weapons and ammunition, dangerous goods, flammable and explosive materials, and important items. The loss of confidentiality and theft of some important materials are closely related to the backwardness of monitoring methods. When it is normally opened, moved, or destroyed, it cannot send an alarm message in time, and indicate the precise location, causing heavy property losses and other losses to the country, ...

AI Technical Summary

Problems solved by technology

The disadvantage is that it is impossible to find out whether the important items being monitored are vibrated or displaced, and the direction is limited, the label is easily damaged, and the important items are easy to be stolen or damaged when unattended

[0006] A monitoring system based on GPRS technology, the system transmits monitoring information through the GPRS network, the disadvantage is that the GPRS signal gain is low, the coverage area is small, and the power consumption is large, and the follow-up service fee is high

With the development of society, 2G base stations have been closed in many areas of the country, resulting in limited application of GPRS technology
