摘要：Recently, the use of ubiquitous sensor network technology has spread vastly. The ubiquitous sensor networks are widely de- ployed in factory auttxnation as they provide effective measuring solution for instruments. The wired/wireless network module, which provides the interface to connect to the u-sensor network, is needed but there is no perfect standardization about the interface. In this situation, the interface compatibility between measuring instrument can be maintained using the IEEEI451 international standard. In this paper, the Wireless Transducer Interface Mcduie （WTIM） based on IEEE1451.5 was designed. It coxnects to the measuring instnmnt, like the muiti-meter, power meter, and etc., to support the RS232 interface. As these devices cannot connect to network without a mod- ule, we use the WTIM to help these devices connect to network sys- ton. Its ftmction was verified through the ubiquitous network connection and data transfer between monitoring PC and measuring instrument. This technology is expected to reduce cost in order to construct the wireless industry automation system using existing devices.

摘要：雄性不育性状被用在植物育种中,以降低种子生产成本。雄性不育分为细胞核雄性不育(GMS)和细胞质雄性不育(CMS)2种类型,在辣椒商业育种中都有应用。因为缺少恢复源,细胞质雄性不育系统在诸如甜椒等一些辣椒品种上并不适用。因此,细胞核雄性不育对于甜椒的种子生产而言就非常重要。本研究构建了一个F2分离群体,利用集群分离分析法(BSA)和扩增片段长度多态性(AFLP)技术获得了一个与甜椒细胞核雄性不育连锁的标记。我们分析了1024对AFLP引物,发现Eco RI ACG/MseIGTT引物扩出了多态性。对多态性AFLP标记所扩增的395bp片段重新设计引物,进行高分辨率熔解曲线分析(HRM)。在92个F2单株中,有87个单株的性状和HRM标记表型相一致。这个HRM标记被定位在AC99连锁图的第5号染色体上。

摘要：To satisfy the requirements of motion control for industrial machine, a multi-axis motion controller based on DSP is developed in this paper. The motion controller consists of DSP which plays a main role in this design;DPRAM to make sure the rapid and reliable communication with host;FPGA to handle the task of address decoder and receiving feed-back encoder signal;and several peripheral logic circuits. In the part of hardware design, overall structure of motion control system is presented. Then, the Feed-Forward Proportional-Integral-Velocity (FFPIV) scheme which introduces KV in term of velocity loop to achieve the accurate, smooth and real-time response is proposed in the software developing part. The experiment data are carried out to indicate that this motion controller has advantages of superior performance and highly machining precision.
