In addition , in order to make the pumps realize constant injection pressure , the expert tuning pid vfvs constant injection pressure control sub - system for pumps is established and relevant software module is developed . the sub - system can control automatically the quantity and rotate speed of the pumps running to realize the pumps optimum run according to the seawater injection plan of the oil field , which realizes constant injection pressure , energy saving and decreases the consumption to a large degree 此外,为平台注水泵机组的优化运行构建了基于专家整定pid控制的变频调速恒压注水控制子系统,并开发了相应的软件模块,完全省却了pid控制器的硬件设备,使得注水泵机组可以根据油田注水量的配注方案优化运行,自动控制注水泵的转速和运转台数,既能实现平稳增压注水,又能在很大程度上节能降耗。
The components in a ha system should support ras features ( reliability , availability and supportability ) , including resources monitor , logic management and system health monitor etc . in fact , ha is a wide domain and a well - designed ha system should embrace reliable communication sub - system , nodes management , quoram sub - system and simultaneous controlling sub - system etc . to achieve the goals above , in this dissertation , it focuses on the universal presentation of resources , resources monitoring , resources failover , logic system and ha in database systems 在高可用系统中主要需要有支持ras特性的功能组件,它包含:资源监控、日志系统、系统健康监控等。事实上,高可用性是一个广阔的研究领域。一个好的高可用性系统应包含一组可靠的通讯子系统、群集成员管理、 quoram子系统以及并发的控制子系统等等,这包含了许多工作。
On the sufficient understanding to the snmpv3 protocol , we put forward to act for the need analysis of the system and design the way of thinking to the safe network management . this design accordings to the specification of snmpv3 completely , is divided into distribute the machine ( dispatcher ) mold , news handling sub - system , safe sub - system based on user - based model , access and control sub - system based on view - based model and its mibs realization , agent initialization sub - system etc . and realize all at last 在充分理解snmpv3体系的基础上,提出了对安全的网络管理代理系统的需求分析及设计思路。本设计完全参照snmpv3规范,对整个系统又分为分发器( dispatcher )模块,消息处理子系统,基于user - based安全模型的安全子系统,基于view - based访问控制模型的访问控制子系统及mib实现,代理初始化子系统等几个分模块,并给予实现。
And then , it describes the design of the minimum system , including the system structure and technique issues of the main modules of the minimum system . also this article discusses the test process control sub - system and the bug management sub - system in detail . it also gives some typical examples to explain the work features of the system 对于航天嵌入式软件测试管理系统进行了较为详细的需求分析,在此基础上应用较先进的软件技术完成最小系统的设计,讲述了各个主要模块的功能和应用的技术要点,并讲述了缺陷管理子系统和测试控制子系统的实现方法,举例说明了系统的工作过程和特点。
