1 First Tuning

1.1 Change Net Type

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;

1.2 Setup RTC

[root@mcuzone root]#date -s 2017.01.05-18:38:48
Thu Jan  5 18:38:48 CST 2017
[root@mcuzone root]#hwclock -w # write RTC to store the time
[root@mcuzone root]#hwclock -r
Thu Jan  5 18:38:56 2017  0.000000 seconds

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
bin       db        include   nfsroot   src       ubi.in
chmod.sh  dbtest.c  lib       sh        src-x
[root@mcuzone /app]#ls x/src-x
Makefile             main.c               sysinit.c
bsp.c                meter_table.c        uart_gprs.c
commap.c             notes.md             uart_mbus_down485.c
db.c                 queue.c              uart_set.c
elect.c              read_heatmeter.c     water.c
gather_V1            readallmeters.c      xml.c
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
buff1.xml    buff3.xml    gather_V1    log.txt      runapp.sh

3 TODO

"使用485组网，是不允许信息主动上推的，必须等待上位要数, 如果多个集中器都往485总线上推数据, 会引发冲突"

void ReadAllMeters(void)
{
    ......
    ......
    if (RPT_ACTIVE == atoi(sysconfig.f_config_value)) { //如果是主动上报, 则发送上报消息
        lnetMod = g_sysConfigHex.netType;

        if (lnetMod != em_net_rs485) {
            //使用485组网，是不允许信息主动上推的，必须等待上位要数, 如果多个集中器都往485总线上推数据, 会引发冲突
            ......
            ......
        }
    }
    ......
    ......
}
