防走失服饰中导航传感器性能评价方法的研究

为了科学系统地选择出适用于不同类型防走失服饰的导航传感器,引入美观性、经济性、舒适性、智能性、导航性能、可靠性、安全性等评价指标,运用层次分析法建立了防走失服饰导航传感器的综合评价体系,采用专家打分法对wifi、蓝牙(iBeacon)、基站定位、GPS、Zigbe、A-GPS等10种导航传感器进行了评分。研究结果表明:防走失服饰必须具备的导航传感器为GPS、A-GPS、基站定位,基站定位可进行通信导航一体化设计。ZigBee、蓝牙(iBeacon)均可解决GPS、基站定位信号较弱场景下的定位问题,可二者择一配备在防走失服饰中。防走失服饰导航传感器的性能评价体系具有较好的可行性,对防走失服饰中导航传感器的选择具有一定的指导意义。

Research on performance evaluation method of navigation sensor in anti-lost clothing

In order to scientifically select navigation sensors suitable for different types of anti-lost clothing,the evaluation indicators such as aesthetics,economy,comfort,intelligence,navigation performance,reliability and security were introduced in this paper.A comprehensive evaluation system for lost clothing navigation sensors was established by using analytic hierarchy process method,and expert scoring method was used to score 10 types of navigation sensors such as wifi,Bluetooth(iBeacon),base station positioning,GPS and Zigbee,etc..The research results showed that GPS and A-GPS were necessary sensors in anti-lost clothing,base station positioning can be integrated for communication and navigation design,and also must be equipped with sensors;ZigBee and Bluetooth(iBeacon)had the similar performance in dissolving the positioning problem in the scenario where GPS and base station positioning signals were weak.Therefore,the performance evaluation system of anti-lost clothing navigation sensors has good feasibility,and it has guiding significance for the selection of navigation sensors in anti-lost clothing.
