The method and importance of scientific handling and using files are analyzed in detail . to use obturation storeroom replace open storeroom , and control the temperature and humidity of storeroom automatically , in order to extend the archives " natural life . the technologies of automatic identification , storage , fetch and agv are put forward to improve automatic level and work efficiency 具体分析了科学管好用好档案资料的方法与重要性,提出了以密闭档案库房替代敞开式库房,并自动监控库房的温湿度来延长档案的使用寿命;提出了采用档案自动识别与存取技术以及agv技术,来提高档案库的自动化程度和工作效率;采取防盗、防火等措施以确保档案库的安全;采用c s或b s工作模式来组建档案库的信息管理网络。
Management information system is developed with vb6 . 0 , and used activex data objects technology c onnecting access database . this project strides over many subject such as electrocircuit , sensor , singlechip , embed system , computer communication , and software engineering , so this reading rneter system is a high automatic level system . the system successfully integrates auto - reading and manual - reading , and realizes automatic managing data , which not only convenience manager , hut alse convenience user 本系统中,电能表的微处理器是在microchip公司提供的pic系列单片机,其汇编程序是在mplab编译环境下开发和调试的;手抄器是land公司的ht - 2800型掌上电脑,其应用程序是在该公司提供的模拟仿真平台上,使用htbase语言设计、开发;上位机系统的开发是使用vb6 . 0 ,并采用activexdataobjects技术通过ado对象访问aceess数据库,从而实现数据管理的目的。
Thermal stress control system actually gather the real - time data of unit sets , compute temperature fields , stress fields and maximum dangerous stress by the math modal , decide target and speedup rotation in every stage of startup process , and justify automatically to realize auto control a serial of processes of turbine , such as speedup , warm - up , connecting net , load changing , stop and unsteady condition etc , and improve automatic level of the unit sets . turbine auto startup ( tas ) system can automatically evaluate steam turbine ' s startup and load changing process according to thermal stress of 热应力控制系统实际是对机组运行参数进行实时采集与监控,通过数学模型实时地计算高、中压缸转子的温度场、应力场分布,以及最危险热应力,以确定启动过程各阶段的目标转数及升速率,并进行自动调整,实现机组冲转、升速、暖机、并网、升负荷、停机以及异常工况下的自动控制,大大提高了机组的自动化水平。
