【摘要】 随着科学技术的突飞猛进,我国的通信事业有了飞速的发展,通信网本身随着基础技术和系统技术的发展走向更高的层次,相应地对电源系统和空调系统的要求越来越高。通信事业和科学技术的迅速发展,使通信设备的自动化性能有了很大提高,为通信系统的集中监控管理提供了可行性。通信电源设备的迅速分散,大量电源设备和空调设备分散在各个模块局内,通过集中监控系统,维护人员可以发现设备故障,如果有必要,可以派人到现场处理,从而使通信局站不必配备一定的维护人员昼夜值守在机房内,进行巡视、抄表等日常维护工作和必要的设备维修、故障处理等。 本论文详细介绍了电源监控的各项知识,包括集中监控的设计原则、集中监控的监控内容、集中监控的结构组成及硬件的功能,详细论述了监控设备的网络结构,并结合潍坊通信公司情况,详细介绍了通信电源集中监控软件PowerDCS的设计和调测过程。 通信电源监控内容包括:高压配电、变压器、低压配电、柴油发电机组、不间断电源UPS、开关电源、蓄电池、空调、环境(包括温度,湿度,水浸,烟雾等)。集中监控一般应有日常维护、故障分析、告警管理和维护提醒等功能。监控系统数据采集根据不同的电源设备设置若干设备监控单元SU(监控模块SM),构成若干相对独立的数据采集系统,智能设备的监控模块本身自行构成数据采集子系统。通过电话网或“97工程网”将监控采集数据传送到电源监控管理中心SC,电源监控管理中心SC通过监控软件PowerDCS实现动态数据画面监视、实时/历史趋势图、实时/历史数据报表/统计/打印、报警与报警打印、实时/历史数据库、设备的遥测、遥信、遥控。 通信电源集中监控技术在通信电源中的应用,标志着通信电源的维护和管理从人工看守式的维护管理模式向计算机集中监控和管理模式转换,为实现电总要求的少人或无人值守奠定了基础。而且,由于采用集中监控,实现了通信电源设更多还原

【Abstract】 With the development of the science and technology, the communication enterprises grow quickly. Based on the progress in the basic and systematic technology, the communication networking is also improving to a higher level. Accordingly, there are more requirements on the power supply system and air conditioning system. Furthermore,moreautomatical communication devices provide more possibilities of central monitoring system. A great deal of power supply devices and air conditioning devices are distributed in separate modules. Using the monitoring system, the maintenance staff can find the malfunction and then send workers to solve the problems on site if it is necessary. Consequently the communication office doesn’t need to keep certain maintenance workers in the computer room whole day and whole night to patrol, take note, repair and correct failure.This thesis introduces the detailed information of power supply control system, such as design principle, content, composition, hardware function and networking structure. It also illustrates the design and measure processing of Power DCS in Weifang Communication Company.Communication power monitoring includes high pressure power distribution, transformer, low pressure power distribution, continuous power (UPS), switch power, accumulator, air condition and environment (temperature, humidity, submerge, smog etc.) The central monitoring system has normal maintenance, malfunction analysis, alarm control and remind function. The monitoring system uses individual monitoring cells -SU (monitoring module SM)- to collect the data from the separate power devices. Several relatively independent data collecting systems consist of many SU and the monitoring modules themselves compose the subsystem. Then the monitoring collecting system could send the data to the power devices control center via telephone network or 97 networks. Finally the control center will use Power DCS to monitor the dynamic menu, draw the live/historic chart, make live/historic data table, analyze data,alarm/alarm print, live/historic database, telemeter, and remote control.The application of the power central control technology is a symptom that the communication power maintenance and management is changing from the personnel checking pattern to computer control pattern, which is the base of the following few worker or no worker management system. In addition, the central control system can also improve the power supply quality. All the testing records and maintenance files can be print out after a certain time and memorized automatically. For example, the charging and discharging curves of the accumulator, the switch on and off time of the diesel generator, electric pressure and current etc can be saved and filed automatically. Thereby it meets the needs of the communication and should be recommended to the communication operators. Since the power central control system was put into use in our company, it works rather well and stable. All the alarm can be reported in time and the operation is easy to learn. So all the staff in our company can use the system properly.更多还原
