At present , the gas supply system is easily operated and controlled but not convenient for fault diagnosis and problem solving , and also not in favor of improving the reliability and safety of launch control because of lacking the working status and data from the automatic record equipment 目前发射场配气系统采用手动控制方式,这种方式虽然简单易实现,但由于没有自动记录设备的运行状态和数据,不利于故障的定位和排除,也不利于提高发射控制的可靠性和安全性。
Picep eliminated the drawbacks existing in traditional measurements ( using light oscilloscope , magnetic tape machine and fault wave recorder ) , such as failure to start automatic recording , low acquisition speed , less synchronous recording channels , joint grounding of channels and less analysis functions for electrical parameters acquired , etc . picep meets the requirements of both production and r & d need of power system Picep解决了传统方法试验方法(光线示波器、磁带机、故障录波器)中不能自动启动记录、采集速度低、同步记录通道少、各通道共地、对测得的电气参数软件分析功能少等弊端,满足了电力系统生产实际和科研的需要。
It has automatic record of learning course , web - based exercise system , message system between teachers and administrators and students , display of learning result . this makes blog more congruous with characteristic of mde and more effective to solve the problems mentioned above 除了具备网络日记的基本功能之外, wll还具有学习历程的自动跟踪、网络作业模块、管理员与师生间的消息系统、学习成绩显示等功能,以使blog的理念和技术更加符合远程教育的特性,有效的解决上述问题。
The completed automation system not only can perform the starting , connecting , frequency and load modulating , disconnecting and stopping functions automatically but also can perform the monitoring , alarming , automatic recording , and performance evaluating functions , etc . in with the dispersed control and centralized management , the system achieves high running effect 最终实现的电站自动化系统不仅可以自动完成各发电机组的启动、并车、调频调载、解列和停机等操作,还可以实现电站运行的监控、报警、自动抄表和运行性能评估等功能。该系统以控制分散、管理集中为指导思想,运行效率得到提高。
Overvoltage automatic recording device is restricted by the way which can get overvoltage from power system for a long time , and ca n ' t make great progress . because realtime recording higher voltage level power system require some special device which can get overvoltage , and some technique difficulty exist . and 10kv distribution network is used to supply power for user directly , its distribution is extensive , equipment is more and electric insulation level is low , it is easy that overvoltage accident occur 因为要对10kv以上更高电压等级的过电压进行实时记录对过电压获取设备的要求高,技术难度大,并考虑到10kv配电网承担着直接向用户供电的任务,分布广、设备多、绝缘水平低和过电压出现频繁,尤其在中性点不接地系统中,更易因过电压造成绝缘事故。
In the trial measurement , the device shows good performance . simulant trial and actual result indicate that method in the paper acquire approving effect . the successful develop of device can improve reliability of distribution , can bring some operating experience for realtime and automatic recording overvoltage in higher voltage level power system 通过现场实际采集的数据说明,该装置可以应用于工程实践中。本装置的研制成功对提高配电网的安全性具有重要的科学意义和良好的应用前景,并能对以后10kv以上电压等级的过电压实时记录装置的研究取得一些经验。
Familiar automatic recording device for overvoltage can just monitor inner overvoltage , but the device introduced in the paper can real time record lighting impulse overvoltage and inner overvoltage together in 10kv distribution system . with the characteristics of overvoltage in the 10kv distribution network , the principle of realtime recording device for overvoltage is introduced by author , and design and develop applied realtime and automatic recording device for overvoltage first 通常的过电压自动记录装置采样频率不高,采样周期短,大多只能监测内过电压,而本装置研究的目的是能够同时监测雷电过电压和内过电压。作者结合10kv配电系统的过电压特点,提出了10kv配电网过电压实时自动记录装置的基本原理,设计并研制成功了实时监测大气过电压和内过电压的监测装置。
The paper also has designed investing management system for xi ' an sinco group including three main modules of investment information management , investment monitoring and decision - making according to modularized systematical developing method based on the developing flat of microsoft access2000 database . the investment information management and the investment monitoring modules have been established . and the system realizes the automatic recording , browsing , searching , analyzing , readout , transferring , statistics , analyzing , criticizing etc . and the standardization of work process and the unity of work standardization 按照模块化的系统开发方法,以microsoftaccess2000为数据库开发平台,设计了包括信息管理、投资监控及投资决策三大功能模块的西安新科集团投资管理系统,建立了投资信息管理和投资监控两大功能模块,实现投资信息的自动录入、浏览、查询、分析、输出、传递、统计、分析、评价等功能,规范了工作流程,统一了工作标准。
