Abstract
This paper proposes a distributed dust monitoring system based on 3G mobile network,which solves the problem of high maintenance cost and less monitoring points of traditional dust monitoring equiment.A dust detector based on the principle of micro charge monitoring is adopted as the front probe,and the amount of dust in the measured area is converted into a 4 mA ～ 20 mA current signal.The current signal is converted into a digital signal by a high precision Analog to Digital Converter (ADC).Then,the Field Programmable Gate Array (FPGA) is used to form the protocol frame of the collected dust concentration value,relay switch signal and other data.Application results show that,this system can display dust concentration in real time,store collected data and replay history data.It also has the advantages of high monitoring accuracy,low maintenance cost,safe operation,and other features.关键词
