建立一个iot平台，可以配置（bms（电压、电流、温度、soh），pcs，电池组、智能电表、空调）多个设备接收modbus，ies104协议 并解析协议 通过mqtt上传到服务端

要建立一个IoT平台，可以配置多个设备接收Modbus和IES104协议，并解析这些协议，并通过MQTT将数据上传到服务端，您可以使用以下Python示例代码作为基础：

from pymodbus.client.sync import ModbusTcpClient
from pyies104 import IES104Client
import paho.mqtt.client as mqtt

# MQTT连接信息
mqtt_broker = "mqtt.example.com"
mqtt_port = 1883
mqtt_username = "your_username"
mqtt_password = "your_password"
mqtt_topic_prefix = "your_topic_prefix"

# 设备配置信息
devices = [
    {
        "name": "BMS",
        "protocol": "modbus",
        "host": "bms_device.example.com",
        "port": 502,
        "registers": [
            {"name": "Voltage", "address": 0x0000, "count": 10},
            {"name": "Current", "address": 0x0010, "count": 10},
            {"name": "Temperature", "address": 0x0020, "count": 10},
            {"name": "SOH", "address": 0x0030, "count": 10}
        ]
    },
    {
        "name": "PCS",
        "protocol": "modbus",
        "host": "pcs_device.example.com",
        "port": 502,
        "registers": [
            {"name": "Data1", "address": 0x0000, "count": 10},
            {"name": "Data2", "address": 0x0010, "count": 10},
            {"name": "Data3", "address": 0x0020, "count": 10}
        ]
    },
    {
        "name": "Battery",
        "protocol": "modbus",
        "host": "battery_device.example.com",
        "port": 502,
        "registers": [
            {"name": "Data1", "address": 0x0000, "count": 10},
            {"name": "Data2", "address": 0x0010, "count": 10},
            {"name": "Data3", "address": 0x0020, "count": 10}
        ]
    },
    {
        "name": "SmartMeter",
        "protocol": "modbus",
        "host": "smartmeter_device.example.com",
        "port": 502,
        "registers": [
            {"name": "Data1", "address": 0x0000, "count": 10},
            {"name": "Data2", "address": 0x0010, "count": 10},
            {"name": "Data3", "address": 0x0020, "count": 10}
        ]
    },
    {

请根据您的实际情况修改代码中的相关参数，包括MQTT连接信息、设备配置信息和MQTT主题前缀。确保您已安装所需的依赖库（pymodbus、pyies104和paho-mqtt）。

这是一个基本的示例，您可以根据您的需求进行进一步的修改和扩展。例如，您可以根据设备的协议类型选择不同的解析方式，并根据需要添加更多的设备和寄存器配置信息。希望对您有所帮助！如果您有任何进一步的问题，请随时告诉我。
