以下所有操作都在 USB 连接集中器后获取的串口终端里操作,参见《集中器本地调试指南》

1.1 更改上行网络

net_type 网络类型:

  • 0 - GPRS
  • 1 - RS485
  • 2 - Ethernet (NOT SUPPORT)
  • 3 - Zigbee (NOT SUPPORT)
typedef enum em_net_mod {
    em_net_gprs = 0,
    em_net_rs485,
    em_net_eth,
    em_net_zigbee
} net_mod;


现场集中器上行使用 RS485 转 Ethernet 组网,因此需将 net_type 改为 1 (RS485):

1.2 校准 RTC

确认集中器内 RTC 时间:

[root@mcuzone root]#hwclock -r
Thu Jan  1 12:38:56 1970  0.000000 seconds


此时间会影响到上行 XML 数据内时间戳,时间不正确,需要根据现在时间校准集线器的 RTC:

[root@mcuzone root]#date -s 2017.01.06-12:38:48
Thu Jan  6 12:38:48 CST 2017
[root@mcuzone root]#hwclock -w # write RTC to store the time
[root@mcuzone root]#hwclock -r
Thu Jan  6 12:38:56 2017  0.000000 seconds



1.3 集中器联网

集中器联网,旨在更新集中器内部抄表核心程序。更新完毕网络即可拔除


打开集中器外壳,插上网线使其可访问外网

集中器 IP:

[root@mcuzone root]#ifconfig eth0 192.168.1.251
[root@mcuzone root]#ifconfig eth0 up

1.4 更新集中器核心程序

确认集中器可访问外网后,先备份原有抄表核心程序:

[root@mcuzone root]#cd /app
[root@mcuzone /app]#ls
buff1.xml      buff3.xml      gatherdb.db    rcS            x
buff2.xml      gather_V0  log.txt        runapp.sh

[root@mcuzone /app]#mv gather_V0 gather_V0.old
[root@mcuzone /app]#ls
buff1.xml      buff3.xml      gatherdb.db    rcS            x
buff2.xml      gather_V0.old  log.txt        runapp.sh


获取修正后的抄表核心程序:

[root@mcuzone /app]#wget http://42.121.85.30/gather_V0
Connecting to 42.121.85.30 (42.121.85.30:80)
gather_V0            100% |*******************************|   316k  0:00:00 ETA
[root@mcuzone /app]#ls
buff1.xml      buff3.xml      gather_V0.old  log.txt        runapp.sh
buff2.xml      gather_V0      gatherdb.db    rcS

[root@mcuzone /app]#ls -l gather*
-rw-r--r--    1 root     root        324430 Jan  6 12:25 gather_V0
-rwxr-xr-x    1 root     root        294111 Jan  5 23:43 gather_V0.old
-rw-r--r--    1 1002     1002         51200 Jan  6 12:13 gatherdb.db

[root@mcuzone /app]#chmod +x gather_V0

[root@mcuzone /app]#ls -l gather*
-rwxr-xr-x    1 root     root        324430 Jan  6 12:25 gather_V0
-rwxr-xr-x    1 root     root        294111 Jan  5 23:43 gather_V0.old
-rw-r--r--    1 1002     1002         51200 Jan  6 12:13 gatherdb.db


试运行:

[root@mcuzone /app]#./gather_V0
Creat QMSG_FILE OK.
g_uiQmsgFd = 0.
XMLBuf_Init OK.
QueuesInit OK!
open_IOControl OK!
......
......
[db.c][each_meter_info][1027] meter_type length : 2
[db.c][each_meter_info][1030] meter_type: 40
[db.c][each_meter_info][1052]135000000
......
......


重启集中器:

[root@mcuzone /app]#reboot

Or press the SW1 button to reset the Collector



1.5 ZLAN 5102 设置

ZLAN 配置工作在 TCP Client 模式,这样集中器通过 RS485 上行的 XML 数据自动被 ZLAN 转发到:

  • Dest IP 为 122.5.18.172 的服务器(调试目的此 IP 为调试人员 PC)
  • Dest Port 为 9011


因此运行于 122.5.18.172 上的上位机程序服务端口为 9011,上位服务器通过此端口获取集中器主动上发的 XML 数据,解析后需向集中器发包响应

没有响应数据包,集中器会认为发送失败,会重复发送上行数据


Zlan5130-config.png



1.6 验证

到此,在调试人员 PC 122.5.18.172 上,开一个 TCP Server 端口在 9011,就能收到,集中器定时上传的 XML 数据:

comcat@jackslab:/work/5d/src/src-x$ sudo nc -l -p 9011

......
......


集中器默认抄表时间间隔为 15 分钟,调试目的,可将时间间隔调整为 2 分钟:

[root@mcuzone root]#cd /app
[root@mcuzone /app]#sqlite3 ./gatherdb.db 
SQLite version 3.10.0 2016-01-06 11:01:07
Enter ".help" for usage hints.
sqlite> select * from t_base_define where f_config_name='collect_cycle';
f_id        f_config_name   f_config_value
----------  --------------  --------------
12          collect_cycle   15             

sqlite> update t_base_define set f_config_value='2' where f_config_name='collect_cycle';
sqlite> .exit


重启集中器,即可生效:

[root@mcuzone /app]#reboot



2 Update APP

Your PC:

$ sudo apt-get install nfs-kernel-server
 
Config the nfs directory:
 
$ sudo mkdir -p /tftpboot/rootfs
$ cat /etc/exports
/work/armv9    *(async,rw,insecure,insecure_locks,no_root_squash)
 
$ sudo /etc/init.d/nfs-kernel-server restart

In collector:

[root@mcuzone /app]#mount -o port=2049,nolock,proto=tcp -t nfs 192.168.1.72:/wor
k/5d/src ./x
[root@mcuzone /app]#ls x

gprs.c               rs485up.c
include              sysfuctions.c

Copy the gather_V1 into collector:

[root@mcuzone /app]#cp x/src-x/gather_V1 .
[root@mcuzone /app]#ls
1runapp.sh   buff2.xml    gather_V0    gatherdb.db  rcS          x

4.2 采集器基本要求

  • 至少 32MB 内存
  • 能跑嵌入式 Linux 系统
  • 下行一路 RS485 最少支持 40 块表,支持多路 RS485
  • 上行到服务器,用以太网,IP 地址和端口可配置,支持 DHCP
  • 通过 http post 请求往内网服务器推送数据
  • 数据间隔可调,最小粒度2分钟,即:每 2 分钟抄一次所有表,随后 http 发往内网服务器
  • 集中器如果数据上行 http push失败,至少要能存储一天的历史数据,待内网服务器恢复后,自动将历史数据推送到服务器


  • meter_id 为电表地址, way_id 为电表的路号,支持一路的电表 way_id 为 1。支持六路三相电监控的路号为 1 ~ 6


  • 电表数据要详细到三相电的每一相,就是上面 xml 格式内的phase A, B,C。每项的监测数据有电压 (U),电流 (I),功率 (P),功率因数 (PF),视在功率 (S)和无功功率 (Q)
  • 三相总的(phase All)数据:功率因数 (PF),有功功率 (P),无功功率 (Q),视在功率 (S),正向有功总电能 (PEP),反向有功总电能 (NEP),正向无功总电能 (PEQ),反向无功总电能 (NEQ)
  • 每一个时间间隔抄表,上行数据的 timestamp 必须统一 (xml: <time>20170908123000</time>)
  • 支持配置 building_id 和 gateway_id


  • 集中器最好支持配置电表的 CT 变比,自动乘上 CT 变比 (可选)

10 有功无功

根据《多功能电能表通信协议》DL/T645-2007的规定,我们将一个平面坐标系的横轴定义为无功功率,纵轴定义为有功功率,二个轴将一个平面划分为四个区域,左上角的为Ⅰ象限,顺时针依次为Ⅱ象限、Ⅲ象限和Ⅳ象限;Ⅰ象限和Ⅱ象限无功定义为正向无功, Ⅲ象限和Ⅳ象限无功定义为反向无功;

我们按下面的要求定义实际功率的方向:

  • 正向有功功率:即输入有功功率,是电网向用户送电,是用户用电功率;
  • 反向有功功率:即输出有功功率,是用户向电网送电,是用户发电功率;
  • 正向无功功率:即输入无功功率,是电网向用户送无功,是用户用无功功率;
  • 反向无功功率:即输出无功功率,是用户向电网送无功,是用户发无功功率;


  • Ⅰ象限无功:输入有功功率,输入无功功率,用户为阻感性负载;
  • Ⅱ象限无功:输出有功功率,输入无功功率,用户负荷相当于一台欠励磁发电机;
  • Ⅲ象限无功:输出有功功率,输出无功功率,用户负荷相当于一台过励磁发电机;
  • Ⅳ象限无功:输入有功功率,输出无功功率,用户为阻容性负载


正向无功是指系统呈感性 反向无功是指系统呈容性 ,正反向都计量无功
