An Important Asset Monitoring Terminal Based On LoRa

Bank money box,Hazardous chemicals,Gas canisters are called valuables or important assets.These important assets often have the characteristics of high single cost and large loss.For these important assets,strict monitoring measures are needed to ensure the absolute safety of every important asset.The main way of monitoring is the way of camera plus human to view the central monitoring platform.This kind of traditional important assets monitoring system has a pain point: people's negligence leads to the alarm is not timely,which causes great losses.At the same time,with the development of Internet of things technology,human beings have stepped into the Internet of things era from the Internet era.Low-power Internet of things technologies,mainly including LoRa long-distance spread spectrum technology and NBIOT narrowband Internet of things technology,have been widely used in various Internet of things applications.The development of the Internet of things provides a new way to solve the traditional monitoring of important assets.Based on the pain points of traditional monitoring methods and the current trend of the development of the Internet of things,a new monitoring method is proposed,which combines the 2.4GHz wireless communication and monitored objects through electronic means to form an active RFID terminal tag.After querying these tag information,the obtained data will be processed and sent to the cloud platform or local database through LoRa long-distance low-power spread spectrum wireless communication technology.Users only need to query the data from the cloud platform or the local database to get all terminal label status.The scheme contains the following contents:The first chapter introduces the current technical background and the development of the Internet of things technology.It is pointed out that the traditional monitoring method has some disadvantages due to the influence of subjective factors.Second,new types of monitoring can now be achieved electronically.It also introduces the development of iot technology,especially the low-power iot technology led by 5G communication,LoRa and NBIOT.Finally,also introduced the author's early research on LoRa technology.The second chapter is mainly based on the technical background of some scheme design ideas.After summarizing and sorting out the thoughts,an important asset monitoring scheme based on LoRa is proposed,and the scheme demonstration and feasibility analysis are made to prove the feasibility of the scheme.The third chapter mainly introduces the system data acquisition function design,mainly introduces the active RFID tag,terminal receiver hardware design,software design.And make appropriate demonstration to the scheme design.The fourth chapter mainly introduces the system data transmission function design.Firstly,the principle of LoRa technology and the content of LoRaWAN protocol are introduced.Then the hardware design and software migration of LoRa module are introduced in detail.Secondly,the design of LoRa gateway is introduced.Finally,the design of the upper computer of the system is introduced.The fifth chapter is system debugging and system demonstration.After the scheme design,the debugging of 2.4GHz electronic tag loss rate,LoRa module and finally the whole system is debugged.Including in the actual project demonstration,introduced the actual implementation of the current program.The sixth chapter is the summary and prospect.
