This system replaces an analogue triggering system that involved time-consuming configuration tasks of Nuclear Instrumentation Module (NIM) circuitry. The new system is a model-integrated computing solution built on Scilab, and provides a means to translate a visual configuration model into code to program a FPGA-based reconfigurable hardware platform. This reconfigurable platform replaces many connections and components of the old system that had to be wired-up manually for experiments. A comparative test of the old and new systems was done, including analysis of safe-timing operation. The new system has a number of advantages, in particular: saving time in setting up experiments, a facility to timeshare expensive NIM electronics, and reducing wear and tear on equipment. But the testing also showed difficulties with the new system, such as longer latencies and jitter compared to the old system. Solutions for these problems are reviewed; but further work is needed to improve responsiveness and scalability of the new system to make it applicable to a wider range of the experiments done at iThemba LABS.","PeriodicalId":192784,"journal":{"name":"2013 IEEE International Conference on Industrial Technology (ICIT)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115139457","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 layer 1 (L1) Inband Protocol in CPRI defines the signalling information that is directly transported by the physical layer. This protocol is required for the L1 link maintenance, exchanging the time critical signalling of the user data and for the system startup of the link. The L1 Inband protocol transfers the reset notifications between the nodes on the CPRI link along with the other control information viz; protocol version, Control & Management (C&M) start-up information and pointers to C&M data. The physical layer of the CPRI is designed in such a way that a very low bit error ratio is achievable without using any of the expensive forward error correction(FEC) techniques. However, reset being very critical signal CPRI defines its own protection mechanism for reset control bit to be implemented in layer 1 of the CPRI protocol. This paper analyses the reset detection and protection requirements of the CPRI standard. The paper presents the possible software approaches and novel hardware implementation techniques for L1 Inband reset detection and protection in CPRI. This paper also analyses the different techniques and sets recommendations for these implementation techniques.","PeriodicalId":192784,"journal":{"name":"2013 IEEE International Conference on Industrial Technology (ICIT)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116960696","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}

In addition to a precise contour forming by a PKM-based machine, its redundant degrees of freedom (DOFs) can be used to improve its energy efficiency. A new approach of tool trajectory planning is proposed in this paper which utilizes redundant DOFs to so position the tool relative to the workpiece during the contour forming that non-regenerative drives involved in the cutting process primarily stay in motoring mode. This excludes energy losses on nonregenerative breaking and significantly improves energy efficiency of milling operation. As the proposed approach reduces the order of the optimization problem, its solution included in the paper is obtained partially analytically and partially numerically. The solution is independent of inaccuracies of dynamic modeling and ensures high accuracy contour forming and stable drive operation. The paper findings are supported by experimental results obtained with the help of an industrial PKM-based machine KIM-1000.","PeriodicalId":192784,"journal":{"name":"2013 IEEE International Conference on Industrial Technology (ICIT)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123802024","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}
