Position information of pallets is important in warehouse management which can enhance the efficiency of pallets picking and sortation. Radio frequency identification(RFID) has been widely used in warehouse for item identifying. Meanwhile, RFID technology also has great potential for pallets localization which is underutilized in warehouse management. RFID-based checking-in and inventory systems have been applied in warehouse management by many enterprises. Localization approach is studied, which is compatible with existing RFID checking-in and inventory systems. A novel RFID localization approach is proposed for pallets checking-in. Phase variation of nearby tags was utilized to estimate the position of added pallets. A novel inventory localization approach combing angle of arrival(AOA) measurement and received signal strength(RSS) is also proposed for pallets inventory. Experiments were carried out using standard UHF passive RFID system. Experimental results show an acceptable localization accuracy which can satisfy the requirement of warehouse management.展开更多

It consists of web geospatial application so-called HydrlS （ Hydrogeological Information System） based on Open Source components and technologies, leading to a feasible and low-cost solution. Therefore, HydrlS permits delivery of data from a number of heterogeneous sources to standards supported by the Open Geospatial Consortium （OGC）. The protocols used for exchanging data are also derived from OGC standards, i.e., WMS （Web Mapping Service）, WFS （Web Feature Service）, and WCS （Web Coverage Service）. Finally, a geoportal was developed, which consists of client-applications that communicate with different Web Services （WMS, WCS, and WFS） through HTTP-requests. A prototype for web-based GIS application was designed using the deegree Framework to provide systematic interfaces and functions. This system was developed to demonstrate the value of making hydrogeological data more widely accessible through client/server architecture. This experience and knowledge already gained in this project will be a source for technology transfer and policy decisions. Otherwise, this will enable user groups to improve the management of their groundwater resources and contribute to enhanced decision support capabilities.展开更多
