摘要
设计开发消防员姿态判定及定位系统。采用9轴传感器捕捉采集姿态信号,利用GPS室外定位技术与UWB室内定位技术相结合定位消防员,采用无线ZigBee网络技术采集数据;通过贝叶斯估计算法对数据进行特征提取,再通过以太网控制器将数据传送到Web服务器,便于终端访问数据;利用云平台将数据反馈到终端显示器上,实现了高精度的定位系统。该系统能够实现远程的消防员姿态判定、精准定位、紧急报警、远程作战指挥等功能。
A firefighter attitude and positioning determination system was designed. The 9 shaft sensor was used to gather at- titude information. GPS outdoor and UWB indoor positioning technology were combined to locate the firefighter, Wireless ZigBee network technology was used to gather the data. Bayes- ian estimation algorithm was used for the data feature extrac- tion. The data was transmitted to the web server for data termi- nal access through the Ethernet controller. The data was dis- played in the monitor by the cloud platform, which realized the high precision positioning system. This system can realize the remote fire fighter＇s attitude determination, precision positio- ning, emergency alarm, remote operation command and so on.
