摘　　要：针对新住宅建筑环境中需要人为手持仪器检测甲苯二异氰酸酯(TDI)、总挥发性有机化合物(TVOC)、甲醛、PM2.5等有害物质的问题,提出一种基于LoRa无线射频技术的室内环境检测系统设计方案。在室内无人的情况下,系统内置各类环境检测传感器,用于采集室内污染物的数据信息,并进行表征分析。当检测到的污染物浓度高于设定的阈值时,通过LoRa无线发射板将当前测量值以双向交互方式发送至接收板,并借助集成的通用分组无线业务(GPRS)通信模块,将数据远程发送至Web端和移动端,便于检测人员进行远程实时监测室内环境质量,提高检测数据的准确性。Aiming at the problem that new residential building environments require human handheld instruments to detect harmful substances such as TDI,TVOC,formaldehyde,PM2.5,etc.,a design scheme for indoor environment detection system based on LoRa wireless radio frequency technology is proposed.When no one is indoors,the system has built-in various environmental detection sensors to collect data information of indoor pollutants and perform characterization analysis.When the detected pollutant concentration is higher than the set threshold,the current measurement value is sent to the receiving board in a two-way interactive manner through the LoRa wireless transmitter board,and the data is remotely sent to the Web and mobile terminals with the help of the integrated GPRS communication module,which is convenient for detection personnel to remotely monitor the indoor environmental quality in real time and improve the accuracy of detection data.
