Research On Environmontal Monitoring System For Printing And Packaging Workshop Based On NB-IoT 5G Communication Technology

This paper proposcs a real-time environmental monitoring system based on NB-IoT(Narrow Band Internet of Things)5G communication technology for printing and packaging workshops in(?)to meet the demand for montorning temperanre,,(?)and fugitive volatile organic compounds(VOCs)(?)costs without the limitations of traditional wiring networks.Based on the analysis of the monitoring moods,a technioal route that(?)#12 system technical(?)#12 embedded software layer and monitoring platform layer.The system uses the ATMEGA328p.AU as main control chip and the DHT11 and MQ-2 sensors to collect(?)and humidity and VOCs concentrations in the workshop;the ML302 wireles module is used to establish network communication via AT conmands;and the OneNET platform is connected via Message Queuing Telemetry Transport(MQTT)to achieve data interiction.based on the OncNET platform,a visual monitoring interface for workshop environmental data has been developed.Using the API interface of the OneNET platform,a workshop environmental monitoring APP based on Androld technolgy has been designed to achieve automatic processing of complex data,improve the efficiency of data analysis and information processing for users,and meet the(?)for querying real-time data and historical data of environmental(?).After testing,the system accomplishes the design objectives and has practical value,#12#12 LORA,etc.It has positive(?)temperuture and humidity and YOCs concentration.
