0 概述 Overview

 中国人民银行金融信息中心数据中心配电室位于北京市西城区德外大街德胜国际中心，现有电力监控系统已运行7年时间，设备型号老旧，经常死机，故障频繁，操作不方便，且备用主机已坏，需要进行改造。具体情况如下：

The power distribution room of the Data Center of the Financial Information Center of the People's Bank of China is located in Desheng International Center, Desheng Street, Xicheng District, Beijing. The existing power monitoring system has been in operation for 7 years. The equipment model is old, often crashes, frequently breaks down, and the operation is inconvenient.

The details are as follows:

配电室供电采用双路供电方式，共有高压柜18个，低压开关柜59个，进线柜8个，电容控制柜 6个，变压器8台。本次改造在不影响机房供电的情况下更换配电室监控系统的软硬件，增加9只环境温湿度传感器。在数据采集点及采集线路不改变的情况下改造，改造后可以降低系统的故障率，操作更便捷，功能更完善，同时提高了系统的安全性，稳定性。

There are 18 high voltage cabinets, 59 low-voltage switchgear cabinets, 8 incoming line cabinets, 6 capacitor control cabinets and 8 transformers in the distribution room.

In this renovation, the hardware and software of the monitoring system of the distribution room will be replaced without affecting the power supply of the machine room, and 9 environmental temperature and humidity sensors will be added.

In the case that the data collection point and the collection line are not changed, the reconstruction can reduce the failure rate of the system, operate more conveniently, function more perfect, and improve the security and stability of the system.

1 用户需求 User needs

1.对实时数据进行统计、分析、计算，产生所需的电压合格率、有功、无功、电流、总负荷、功率因数、电量日/月/年大值、小值及时间、日期、负荷率、数字输入状态量逻辑运算值等，设备正常/异常变位次数并加以区分等。

Conduct statistics, analysis and calculation on real-time data to generate required voltage qualification rate, active power, reactive power, current, total load, power factor, large value and small value of electric quantity daily/monthly/year, time, date, load rate, logical operation value of digital input state quantity, etc., and distinguish normal/abnormal device displacement times, etc.

2.为了防止工控机在运行中出现故障要求两台服务器同时工作并且接收数据一样。

In order to prevent the failure of INDUSTRIAL computer in operation requires two servers to work at the same time and receive the same data.

3.为了采集的可靠性本项目采用工业网关做为采集设备，本网关具有数据存储功能且具备两个网口同时给两台服务器转发数据。当其中一个网关有故障时只需要把采集端子更换到另外一台备用网关即可。

In order to improve the reliability of collection, this project adopts the industrial gateway as the collection equipment. This gateway has data storage function and two network ports to forward data to two servers at the same time.

When one of the gateways is out of order, it is only necessary to replace the acquisition terminal to another standby gateway.

4.全数据备份，能够将数据库中所有信息备份；

Full data backup, able to backup all information in the database;

5.定时自动备份，能够设定自动备份周期，对数据库进行自动备份；

Timing automatic backup, automatic backup cycle can be set, automatic backup of the database;

6. 历史数据恢复，能够依据历史数据备份文件进行历史数据恢复；

Historical data recovery, historical data recovery can be carried out according to the historical data backup files;

2 系统方案 System solutions

本项目客户关心的是系统的稳定性及安全性，要求系统和网络做双机冗余处理，保障数据的安全性。在双网冗余系统中，主机和从机都使用两个网络适配器，并分配在两个不同的网段，主/从机之间存在两个网络连接。两个网络互为备用，可保证主/从机之间的可靠网络通信。双网冗余系统的切换逻辑与单网冗余系统的区别就是在主/从机之间探询对方状态时增加了活动网络与备用网络的切换。以备份站探询活动站状态为例：当备份站通过活动网络向活动站发送探询命令，如果发现没有得到活动站在规定时间内的正确应答，备份站并不立即将活动站判断为故障站，而是自动切换到备用网络再次向活动站发送探询命令。如果备用网络通信正常，则将备用网络切换为活动网络，并将故障的网络状态在报警信息中显示出来。

The client of this project is concerned about the stability and security of the system, and requires the system and network to do double-machine redundancy processing to ensure the security of data.

In a dual-network redundant system, both the host and the slave use two network adapters and are assigned to two different network segments, with two network connections between the master and slave.

The two networks are mutually standby to ensure reliable network communication between master and slave.

The difference between dual network redundancy system and single network redundancy system is that the switch between active network and standby network is increased when the master/slave machine is inquiring the state of each other.

For example, when the backup station sends a query command to the active station through the active network, if it is found that the active station does not receive the correct response within the specified time, the backup station does not immediately judge the active station as a failure station, but automatically switches to the standby network and sends the query command to the active station again.

If the standby network communication is normal, the standby network is switched to an active network and the state of the failed network is displayed in the alarm message.
