In order to get high precision position information of railroad vehicles, modules and subsystems such as GPS module, wheel sensors, and RFID tags are used for various detection methods. Among the detection methods, position detection based on RFID tags placed onto the sleepers of the track is examined in this paper. Position information of each tag is transmitted to the reader installed at the bottom of railroad vehicle, following the wireless power transfer from the reader coil to the tag coil. By the wireless power transfer, the energy required for the position information transmission is harvested by each tag. The wireless power transfer mechanism from the reader coil to the tag coil is the magnetic induction, so power transfer efficiency is substantially affected by the relative location and relative tilting direction of the reader coil to the tag coil. From this viewpoint, improved power transfer efficiency can be achieved by tilting coils. Two tilting coils, with their tilting angles favorable to the reader coil position, which is slightly off the axial position, and a leveled coil are combined. The power transfer efficiency obtained from these three coils is compared with the one by the conventional leveled reader coil. Due to tilting directions of the reader coils, significant gain is obtained even at off-axis positions of them. Simulation to show the improved efficiency by tilting coils is executed and the results are shown.","PeriodicalId":205916,"journal":{"name":"2015 International EURASIP Workshop on RFID Technology (EURFID)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114965097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The localization of a conventional active UHF RFID transponder has obvious drawbacks in the needed hardware on the reader side. The transponder sends only its label and no additional position information is available at the reader. Therefore, a direction finding system and a received signal strength (rss) detector for distance estimation in addition to the reader itself is needed. The huge hardware effort required reader side can be prevented by developing a transponder with an integrated GPS Module for localization. Thus, the focus is on a small transponder design, which leads to a trade-off between the requirements of the desired performance and the realization of the localization system, consisting of an active GPS-UHF transponder and the corresponding reader unit. Especially the conditions for the communication between the transponder and the reader related to limited power supply has to be minded. Furthermore, the transponder realization is shown and the considerations were metrological demonstrated.","PeriodicalId":205916,"journal":{"name":"2015 International EURASIP Workshop on RFID Technology (EURFID)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126568737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We move from our recent work, where we have shown that an UWB-enhanced architecture, that guarantees full backward compatibility with ISO/IEC 18000- 6C UHF standard, can improve by approximately 25% the performance in terms of success rate and energy consumption. The second step is concerned with the proposal of a further tag identification protocol, that is based on compressive sensing (CS) and UWB: the main feature of the proposed scheme is that it exploits UWB information to reduce the ID search space of CS decoding. This hybrid technique is still oriented to further decrease the speed in tag identification, while reducing the computational complexity if compared to an UHF-RFID only protocol. Finally, we extend our approach to the case of multiple readers, that do not only improve coverage, but can also further improve the performance indexes: in this case a cooperative approach is proposed in order to also manage readertag collisions and reader-reader collisions other than the typical tag-tag collisions.","PeriodicalId":205916,"journal":{"name":"2015 International EURASIP Workshop on RFID Technology (EURFID)","volume":"72 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130328718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
