Intelligent High-rise Building Environment Monitoring System Based On ZigBee And NB-IoT Cloud Platform

With the rapid development of Internet of Things technology,the digitization and intelligentization process of high-rise building environmental monitoring is accelerating constantly,and various solutions for high-rise building environmental data monitoring emerge one after another.Due to the complex internal environment of buildings,it becomes difficult to detect environmental parameters and monitor equipment.To solve the above problems,this paper proposes a ZigBee and NB-IOT cloud platform based intelligent high-rise building environment monitoring system design.This scheme applies ZigBee technology and NB-IOT technology to the intelligent management of high-rise buildings,and makes full use of its advantages of long distance,low power consumption and large connection,so as to solve the problems of on-site data collection,transmission and monitoring of the internal environment of buildings.In this paper,by studying relevant experiments of building internal environmental data monitoring and combining ZigBee and NB-IOT wireless sensor network technologies,the intelligent monitoring system of the Internet of Things for high-rise buildings is designed and completed.This system is connected to OneNET cloud platform through BC26 communication module,which can not only complete the collection and upload of environmental data,but also realize the sending of device trigger instructions.The design content of this system has two aspects,namely hardware and software.The hardware part needs to complete the design and detailed description of the hardware circuit of the terminal perception node and communication module.The terminal node chooses CC2530 chip as the processor,and the NB-IOT communication module USES BC26 chip.The hardware circuit includes the control module and peripheral circuit,data acquisition sensor module and network communication module.The software part includes data acquisition module,BC26 communication module and cloud platform monitoring.OneNET is selected as the cloud platform and MQTT protocol is adopted to complete the communication.Finally,functional tests were carried out on sensor node data acquisition and cloud platform monitoring respectively,that is,environmental data acquisition was uploaded and trigger instructions were issued,and the test results were analyzed.The experimental results show that the system can carry out real-time and effective data transmission and realize cloud platform monitoring.When the environmental parameters exceed the set value,the cloud platform sends triggering instructions to the E-mail.The initial design principles and objectives of the system are accomplished.Figure.[42] table [5] reference [65]...
