摘　　要：为了提升液化气监控系统的灵活性和数据处理的精度并减少数据量的上传,提出了一种基于加权数据融合算法的移动液化气监控系统.根据MATLAB/Simulink图形仿真环境对加权数据融合算法和算术平均法进行的模拟效果对比实验,证明了加权数据融合算法的优越性;利用实地布置的同类型的多传感器进行数据采集,并将采集的数据以JSON格式存入服务器数据库内;最后,移动端通过HTTP请求的方式获取数据.结果表明:该系统在提高数据处理的精度并减少数据量的同时,还保证了数据的上传速率,使系统可以很好地应对液化气爆炸的突发性.To reduce the amount of upload data and improve the accuracy and flexibility of liquefied gas monitor system,a mobile liquefied gas monitoring system based on the weighted fusion algorithm was proposed. The fact that the weighted fusion is better than that of the arithmetic method,was proved by the comparison between them on MATLAB / Simulink. Then,data was collected from field,and was uploaded to the database in JSON type. The HTTP method was used to get data from the server by the terminal. The experiment shows that the system proposed in this paper reduce the amount of data and improve the accuracy. Meanwhile,it can guarantee the speed of data uploading which can reply to the emergency of explosion.
