Considering the special demand of substation ' s bay unit and the characteristic of can2 . 0b protocol , a high effective , reliable , and well functional protocols is formulated to fulfils the demand of real time of system 在通讯软件处理方面,充分考虑到变电站间隔层的具体要求,同时结合can2 . 0b协议的特点,制订了一份能够充分满足系统要求的、较高效率及可靠性的通讯协议,满足了系统对实时性的要求。
In this work , we review these processes first and then build a software that uses internet as public channel to perform these post - processing . with this software we can carry out the post - processing in qkd and simulate the overall quantum encryption process 本文论述量子密码中经典通道的通讯过程,并建立一个用internet作为经典通道的量子通讯软件,用这个软件可以实现经典通道的处理和模拟整个量子通讯的过程。
Recently , network integration technology , communication software technology , optimal control technology , which have been applied at some degree on large - scale pumping station . at present , there are many problems so that model which worth extending has been not built 近年来,网络集成技术、通讯软件开发技术、优化控制技术,在大型泵站监控系统获得了不同程度地应用,但目前仍然存在着许多问题,至今还没有形成一个值得推广的模式结构。
On the base of communication controller , we adopt the method , which combine the information redundancy of software redundancy and the redundancy transmission . the communication software is programmed on the platform of vc + + 6 . 0 . therefore , we can advance the reliability of serial communication 在使用通讯控件的基础上,采用软件冗余中的信息冗余和冗余传输相结合的方法,编写vc + +环境下的工控机与plc通讯软件,达到提高系统串行通讯可靠性的目的。
In the monitoring and control aspect , we establish the layered and distributed architecture of the computer network based on the pattern of dcs by the configure software , and developed the communication software among the multi - stations and between the instruments and the pc 论文分为两个部分,在计算机监控方面,以gefanuc公司的组态软件cimplicity为基础,构造了基于dcs模式的分层分布式计算机监控网络结构。开发出多站点间、工业仪表与站点间的通讯软件。
On december 15 , 2003 , tencent s new im software - tencent messenger or tencent tm was publicly launched . following qq and rtx , tm is another powerful freshman for tencent im products line and aims to offer im service for cyber users to communicate with friends under office environment 2003年12月15日,腾讯一款最新的即时通讯软件tencent messenger简称腾讯tm对外发布,此版本是腾讯im产品线中继qq和rtx之后,又一个强有力的补充,推荐希望在办公环境中和熟识朋友即时沟通的网友下载使用。
It provides various kinds of function , such as flow chart , real time dynamic display , real time and historical trend chart , alarm , report , data logging , parameter setting etc . the function of flow calculation and compensation , data acquisition and storage , communication is also provided in flow calculator 计算机实现hmi人机接口和数据管理平台,具有工艺流程图、实时动态显示、实时和历史趋势图、报警、报表、数据记录、参数设定等功能。积算单元固化有流量计量专用软件和通讯软件,实现数据采集、计算、补偿、存储、通讯等功能。
It emphasizes on development of ct drive of profibus and ge 90 - 30 plc communication software , and draw a conclusion that using site bus can make the relation between plc and drives more close and can expediently exchange huge amount of data between them , therefore make it possible to realize epistatic control 本章重点探索了基于profibus的叮马动器与m90 30plc的通讯软件的开发,由此得出了使用现场总线后可以使得plc与驱动器之间的联系更为紧密,可以彼此方便地交换大量数据,从而使上位监控成为可能。
Hardware research focuses on interface circuit including simulating sensor simulating actuator and monitoring power . software design consists of data collection commutating software graphics interface and data processing . the project can meet the requirement for engineering application through primary testing 其硬件研究主要是接口电路设计,包括发动机传感器信号模拟、执行机构信号模拟、激励电源监测;软件研究包括数据采集软件、网络通讯软件、人机交互界面和数据处理软件设计。
The ibm - pc computer can inspect and monitor the distant controller . ( 3 ) we used the counter and timer to improve the rate of success and the system containing error ability and avoid the infinite cycle when we design the serial communication software . moreover we adopt the checking out method ( 3 )在串行通讯软件设计方面,采用了重复次数计数器和定时器,从而大大提高了通讯的成功率和系统的容错能力并且避免了发生死锁情况;在数据传输过程中,采用累加和的校验方法,保证了系统传输的安全性、可靠性。
