In succession , contraposing the 101 protocol and dl / t 645 protocol , using msp430 chip fufills the devise of the converter . in software designing , completes the devise of 101 protocol substation part and the master part of 645 protocol , realization communicating between the two protocols . based on it we expands some functions to make the converter possess the fuction of data handle and data saving such as possessed by the commonly remote terminal units 接着,针对101规约和国标dl t645多功能电能表规约这两种不同通信协议,运用msp430芯片设计了电力监控转发器。在监控转发器的软件设计中完成了101规约的子站部分设计和电能表规约的主站部分设计,实现了这两种协议间的信息传递,并在此基础上做了适当的功能扩展,让监控转发器具备了一般远方终端所具备的数据处理和数据保存等功能。
The siphon type can not realized automatic measurement and data handling and the tipping bucket type dynamic accuracy is not high . at the same time , the bigger inaccuracy exists in these two kinds of measurement methods . along with the science and technology and the requirement of society development , the automation to the meteorological factor gathers and meteorological data saves and data handling have been put forward to the higher requirement 气象部门长期使用的雨量计为虹吸式或翻斗式的,虹吸式不能实现自动测量与数据处理,翻斗式动态精度不高,同时,这两种方法测量降雨量存在较大的误差,随着科技和社会发展的需求,对气象要素的自动采集和气象数据的自动存储、数据处理也提出了更高的要求。
Implement accounting electrical calculation to the principle of systematic built - in control the established goal that will accord with built - in control , to select and establish corresponding strategy according to the characteristic of data handling , reinforce organization control , clearly duty limits of authority and to strengthen accounting data to handle the control of unit process of cargo handling , design the accountant with excellent development software , reinforced accounting electrical calculate melt the development control of information system , follow software development program strictly 实施会计电算化系统内部控制的原则既要符合为部控制的既定目标,又要根据数据处理的特点选择和制定相应的策略,一是强化组织控制,明确职责权限;二是强化会计数据处理操作过程的控制,设计开发优秀的会计软件;三是强化会计电算化信息系统的开发控制,严格遵循软件发展程序。
Moreover , taking the fatlute model of the covering parts of motorcycle for an example , it discussed the measurement plan method of prototype and the process of data handling . 2 . pretreatment of points cloud according to the characteristic of scattered point cloud data , the issue elaborated in detail points cloud registration , which was based on the shape characteristic matching 论文运用一级模糊综合评判方法研究了复杂曲面产品的数字化策略,并以摩托车覆盖件油泥模型为例,讨论了样件的测量规划方法和数据的处理流程; 2 、点云数据的规范处理针对散乱点云数据的特点,详细阐述了基于形状特征匹配的点云对正方法。
According to the requirements of disign , the system apply mcu at89c2051 to extend 32 keybords , and meantime the system can use battery which can be recharged to supply power . as a whole , the system charact eristic of inputting by keyboard and interacting by chinese characters can display and store spectrum data automatically and accomplish data handling . what ' s more . the system can communicate with other computers by the interface of rs - 232c 同时,为了实现人机交互,系统采用at89c2051扩展了32键键盘。在系统的供电方面系统可采用充电电池供电。总体来说,系统采用按键输入,汉字人机对话,能自动显示和存储测量谱线,并完成数据处理工作,除此之外,系统可通过rs - 232c与其它计算机联机使用。
