我需要一段智慧园区的架构代码

以下是一个智慧园区的架构代码示例：

from flask import Flask, request
import json
import requests

app = Flask(__name__)

# 设备管理模块
class DeviceManager:
    def __init__(self):
        self.devices = []

    # 添加设备
    def add_device(self, device):
        self.devices.append(device)

    # 获取所有设备信息
    def get_all_devices(self):
        return self.devices

    # 根据设备ID获取设备信息
    def get_device_by_id(self, device_id):
        for device in self.devices:
            if device["id"] == device_id:
                return device
        return None

# 传感器数据管理模块
class SensorDataManager:
    def __init__(self):
        self.sensor_data = []

    # 添加传感器数据
    def add_sensor_data(self, data):
        self.sensor_data.append(data)

    # 获取最新的传感器数据
    def get_latest_sensor_data(self):
        if len(self.sensor_data) > 0:
            return self.sensor_data[-1]
        else:
            return None

# 警报管理模块
class AlarmManager:
    def __init__(self):
        self.alarms = []

    # 添加警报
    def add_alarm(self, alarm):
        self.alarms.append(alarm)

    # 获取所有警报信息
    def get_all_alarms(self):
        return self.alarms

    # 根据警报ID获取警报信息
    def get_alarm_by_id(self, alarm_id):
        for alarm in self.alarms:
            if alarm["id"] == alarm_id:
                return alarm
        return None

# 初始化模块
device_manager = DeviceManager()
sensor_data_manager = SensorDataManager()
alarm_manager = AlarmManager()

# 设备管理API
@app.route('/devices', methods=['GET', 'POST'])
def devices():
    if request.method == 'GET':
        devices = device_manager.get_all_devices()
        return json.dumps(devices)
    elif request.method == 'POST':
        device = request.get_json()
        device_manager.add_device(device)
        return "OK"

# 传感器数据API
@app.route('/sensor_data', methods=['GET', 'POST'])
def sensor_data():
    if request.method == 'GET':
        data = sensor_data_manager.get_latest_sensor_data()
        return json.dumps(data)
    elif request.method == 'POST':
        data = request.get_json()
        sensor_data_manager.add_sensor_data(data)

        # 判断是否触发警报
        if data["value"] > 100:
            alarm = {"id": len(alarm_manager.get_all_alarms()) + 1, "message": "传感器数据超过阈值"}
            alarm_manager.add_alarm(alarm)

            # 发送警报通知
            requests.post("http://example.com/send_alarm_notification", json=alarm)

        return "OK"

# 警报API
@app.route('/alarms', methods=['GET'])
def alarms():
    alarms = alarm_manager.get_all_alarms()
    return json.dumps(alarms)

if __name__ == '__main__':
    app.run()

该示例代码使用 Flask 框架实现了一个智慧园区的架构，包括设备管理、传感器数据管理和警报管理三个模块。其中，设备管理模块用于管理园区内的设备，传感器数据管理模块用于管理传感器收集到的数据，警报管理模块用于管理园区内的警报。该代码还包括三个API，分别用于设备管理、传感器数据和警报。API可以通过 HTTP 请求来访问，从而实现对园区的管理和监控。
