【摘要】 为了实现城市环境参数的分布式检测和集中统计管理,设计了一个空气环境质量监测系统。该系统分为上位机监控中心和下位机检测与传输终端两部分,下位机采用MSP430F149单片机作为控制核心,以温湿度传感器SHT11和PM2.5传感器进行数据采集。下位机有液晶显示,可以实时显示测量数据,并可手动设置报警值,检测数据同时通过Sim900无线模块传至监控中心。监控中心完成空气环境质量数据的统计管理,生成报表,便于管理部门做出决策。该系统已经在大学校园环境下进行了测试、应用,效果良好。更多还原

【Abstract】 An air environment quality monitoring system was designed to realize the distributed detection of urban environmental parameters and the centralized statistics management of the parameters.This system consists of two parts;the PC monitoring center and the detection and transmission terminal.The latter uses a chip microprocessor of MSP430F149 as the control core,and collects data with the temperature & humidity sensor of SHT11 and the PM2.5 sensor,and the collected data is simultaneously shown on a LCD.At the same time,it transmits them to the monitoring center by the Sim900 module,in which the local module can set the alarm value.The monitoring center conducts the statistical management of the air environmental quality data to generate the report for management departments to make decision.The system was tested and used in the campus environment and its good performance was verified.更多还原
