In a nonattendant substation that has operated for less than one year , more or less erosion has occurred on the surfaces of all copper materials 摘要一座投运不到一年的无人值守变电站，所有铜质料表面均出现了不同程度的腐蚀；经测试分析，其腐蚀原因为硫化氢气体腐蚀。
Because its orientation is uniquely production - oriented , its " self - service " design lets its fast - printing techniques abandon the traditional " serve everyone " strategy 由于是定位于“生产型”设备，其独特的“无人值守”设计，让快印技术摆脱了传统的“人海战术” 。
Now , full automation and non - attended substation have become the developing trend of the roboticized attemper of electrical network and atommatization of power system 应该说，实现变电站综合自动化和无人值守，已经成为电网调度自动化和电力系统自动化发展的必然趋势。
With the rapid development of telecommunications industry , manless on duty is becoming a necessary trend in communication power supply supervision 现代电信事业的迅猛发展，使得实现通信机房的无人值守或者少人值守，对通信电源进行计算机管理已成为电信事业发展的必然方向。
In view of the characteristics of manless on duty , this paper studies communication power supply supervision system in systematic analysis and software development 该文主要从系统分析和软件开发的角度，针对无人值守(少人值守)通信电源监控系统的特点，对通信电源集中监控系统作了一些研究。
The system uses hpc as a detector , based on the computer and network technology , reaches the design requirements of high - sensitivity , wider range , full automation and no - man on duty 该系统采用高压电离室为探测器，利用计算机及网络技术，基本达到了灵敏度高、量程宽、全自动无人值守的设计要求。
This paper presents a new structure orient to unattended low voltage level distribution station automation , and designs corresponding configuring supervisory and control software system 本论文提出一种面向低电压等级配电所的新型无人值守配电所自动化系统结构，同时，为系统设计相应的具有组态功能的监控系统软件。
Currently sewage in sewage pumping station system is pumped manually . so the station is working in low water level and energy is consumed . this mode ca n ' t predict the inflow ' s changing 当前污水泵站排放系统主要采用人工值守方式排水，低水位高扬程耗能严重，且缺乏预测能力，流量洪峰来临时易产生污水溢出污染。
It enables the management to use their erp system to remotely manage the tasks such as production , logistics , sales , and cash flows . the scale controller is designed with the basic functions weighing 采用嵌入式技术设计，将传统的称重显示控制器和计算机技术融合在一起，使称重计量实现了网络化和无人值守的自动化管理。
With these technologies , the centralized monitoring and control in control centre and no duty on field are realized . all these designs improve the production efficiency and quality of water , reduce production cost 真正实现了控制室集中监控、生产现场无人值守，大大提高该水厂的生产效率、供水质量，降低了成产成本。
