Description: 无线传感器网络的主要功能是实现数据发布,在接收到信息查询时能够以有效的方式传输给查询者.目前的数据发布方式通常基于洪泛机制查询信息,浪费了有限的能源.虽然一些最近的数据发布协议从不同程度上解决了这一问题,但不能保证查询成功率.基于圆形节点分布网络模型提出了一种既能减少能源消耗,又能提高成功率的数据发布模式——直径-弦模式DCS(diameter-chord scheme).该模式利用了每个圆的弦都存在一个直径与之垂直相交的性质.在此基础上提出了Two-Phase协议.它在信息查询时分成两个工作方式不同的阶段进行,在第1段查询不中时触发第2段查找.为了减少Two-Phase的延迟,提出了基于优先级和概率转发两种解决方法.理论分析和实验结果都表明,所提出的数据发布协议具有较好的性能.

Description: 增量旋转编码器选型有哪些注意事项？
应注意三方面的参数：
1． 械安装尺寸，包括定位止口，轴径，安装孔位；电缆出线方式；安装空间体积；工作环
境防护等级是否满足要求。
2． 分辨率，即编码器工作时每圈输出的脉冲数，是否满足设计使用精度要求。
3．电气接口，编码器输出方式常见有推拉输出（F 型HTL 格式），电压输出（E），集电极开路（C，常见C 为NPN 型管输出，C2 为PNP 型管输出），长线驱动器输出。其输出方式应和其控制系统的接口电路相匹配。如何使用增量编码器？-Selection of incremental rotary encoder which note? Should pay attention to three parameters: 1. Armed installation size, including positioning the mouth only, shaft diameter, mounting hole bit cable round way installation space volume work environment meets the requirements of protection rating. 2. Resolution, that is, the work of each encoder output pulse a few laps, whether the use of precision to meet the design requirements. 3. Electrical interface, encoder output has push-pull output common (F-type HTL format), voltage output (E), open collector (C, common C for the NPN-tube output, C2 for the PNP-tube output), long-term drive output. The output should be and its control system interface circuit match. How to use the incremental encoder?
