Pseudollites are ground-based transmitters that can provide similar navigation measurements as GNSSs. GH-LPS developed by NUDTis a new pseudolite system allows centimeter-accuracy single-point positioning for a mobile or static device. Carrier phase observations are commonly used in high-precision positioning applications, due to their millimeter precisions. Any cycle slip, if remained undetected, would deteriorate the high accuracy positioning. Hence, it is crucial to handle the cycle slips in the carrier phase measurements for GH-LPS. Carrier phase-based RAIM (CRAIM) algorithm is proposed to detect and estimate small cycle slips. In order to evaluate the performance, a kinematic test was conducted. The experiment demonstrated that the CRAIM method can be used to solve the problem of small (e.g. 1 cycle) cycle slips and GH-LPS can provide single point positioning with centimeter-level accuracy and sub-centimeter level precision.","PeriodicalId":419168,"journal":{"name":"2019 14th IEEE International Conference on Electronic Measurement & Instruments (ICEMI)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132232956","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}

For better application, it is necessary to carry out in-depth analysis and research on the magnetic levitation system and to process the data of the suspension. Since the rejection magnetic levitation system has a better balance range than the suction type magnetic levitation system, a rejection magnetic levitation system is designed. The dynamic equation of the rejection magnetic levitation system is established by analysis and the simulink system simulation is carried out according to the established dynamic equation. The stability balance of the repulsion magnetic levitation system is proved. The measurement data of the magnetic levitation system under external vibration conditions were measured by experiments and field experiments, and the external interference signals were removed by wavelet analysis. The experimental results verify that the designed rejection magnetic suspension system can work stably and has strong impact resistance. This design analysis method provides a theoretical basis for the wide application of magnetic levitation systems","PeriodicalId":419168,"journal":{"name":"2019 14th IEEE International Conference on Electronic Measurement & Instruments (ICEMI)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130122905","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}

Traditional measurement training is subject to economics, repeatability, safety, etc. The independent practice and teaching interaction in the training process are not ideal. This paper proposes the application concept of integrating virtual reality technology into the measurement training system. The trainee can interact with the virtual reality environment in real time, effectively avoiding the waste of measurement resources and improving the safety and repeatability of measurement training. At the same time, the system can provide the super immersion feeling that the traditional training mode can not provide, so that the trainees can feel the real measurement environment, improve the field measurement support ability, and effectively enhance the training effect. For the multi-party joint guarantee measurement task, the distributed characteristics of the system can be utilized, so that the metering personnel can still perform joint training in the same training scenario in different regions, and realize systematic joint training and joint training.","PeriodicalId":419168,"journal":{"name":"2019 14th IEEE International Conference on Electronic Measurement & Instruments (ICEMI)","volume":"231 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131478281","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}

One set is a single crystal calibration device, and LiF crystal can realize continuous emission of (8.1-37.9) keV single-energy X-ray; The other set is a dual crystal calibration device. Si220 crystal and Si551 crystal can realize continuous light emission of single energy x-ray in the energy range of (38-160) keV. The X-ray energy spectrum, energy resolution and energy response of the calibration device were studied by standard high-purity germanium detectors.

Image recognition is one of the important research directions in the field of computer vision. The traditional image recognition method is to extract features by constructing feature descriptors and then classify them by classifiers, such as gradient direction histogram and support vector machine. These methods generally have the problems of poor robustness and insufficient ability to extract features in complex application scenarios. At the same time, convolutional neural network has not been well applied in image recognition due to its large amount of computation and slow speed. With the development of GPU, the parallel computing capability has been greatly improved. This paper designs a GPU acceleration method for the driver’s seatbelt detection system based on CNN. The system is based on the Deconv-SSD target detection algorithm for vehicle detection, the Squeeze-YOLO algorithm for vehicle front windshield location, and the semantic segmentation for seat belt detection. Based on the characteristics of GPU, through the off-line merging bath normlization and convolution layer, Tensorrt model conversion technology to realize the GPU optimization speed. The results show that the proposed acceleration method can effectively improve the detection efficiency.","PeriodicalId":419168,"journal":{"name":"2019 14th IEEE International Conference on Electronic Measurement & Instruments (ICEMI)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115498914","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}
