Python 代码实现高性能分布式并行异构智能社区管理统筹系统
用户管理模块
处理用户注册、登录、权限管理等功能。 代码实现应包含用户认证、授权和会话管理等。
from flask import Flask, request, jsonify, session
from werkzeug.security import generate_password_hash, check_password_hash
app = Flask(__name__)
app.secret_key = 'your_secret_key'
# 假设有一个用户数据库
users_db = {
'admin': generate_password_hash('admin123')
}
@app.route('/login', methods=['POST'])
def login():
data = request.get_json()
username = data.get('username')
password = data.get('password')
if username in users_db and check_password_hash(users_db[username], password):
session['user'] = username
return jsonify({'message': 'Login successful!'}), 200
else:
return jsonify({'message': 'Invalid credentials'}), 401
@app.route('/logout', methods=['POST'])
def logout():
session.pop('user', None)
return jsonify({'message': 'Logged out!'}), 200
@app.route('/register', methods=['POST'])
def register():
data = request.get_json()
username = data.get('username')
password = data.get('password')
if username in users_db:
return jsonify({'message': 'User already exists!'}), 400
users_db[username] = generate_password_hash(password)
return jsonify({'message': 'User registered successfully!'}), 201
if __name__ == '__main__':
app.run(debug=True)
数据收集与监控模块
实时收集社区各类传感器数据,如环境监控、安防系统等。 代码实现包括数据采集、传输和存储机制,可能需要考虑消息队列或流处理系统的使用。
import pika
import json
def callback(ch, method, properties, body):
data = json.loads(body)
# 假设数据是从传感器来的
print(f"Received data: {data}")
def start_monitoring():
connection = pika.BlockingConnection(pika.ConnectionParameters('localhost'))
channel = connection.channel()
channel.queue_declare(queue='sensor_data')
channel.basic_consume(queue='sensor_data', on_message_callback=callback, auto_ack=True)
print('Waiting for sensor data. To exit press CTRL+C')
channel.start_consuming()
if __name__ == "__main__":
start_monitoring()
资源分配与调度模块
动态分配和调度社区内的资源,如能源管理、设备调度等。 代码实现应支持资源优化调度算法,可能需要并行计算框架的支持。
from multiprocessing import Pool
import random
def allocate_resource(task_id):
# 模拟资源分配
resource = random.choice(['Resource1', 'Resource2', 'Resource3'])
print(f"Task {task_id} allocated to {resource}")
return resource
if __name__ == "__main__":
tasks = [i for i in range(10)]
with Pool(4) as p:
results = p.map(allocate_resource, tasks)
print("All tasks processed.")
智能决策模块
基于收集的数据进行分析,提供智能决策支持,如异常检测、预测分析等。 代码实现可以采用机器学习模型,或者结合规则引擎进行决策支持。
from sklearn.ensemble import RandomForestClassifier
import numpy as np
# 模拟数据集
X = np.array([[1, 2], [2, 3], [3, 4], [4, 5]])
y = np.array([0, 1, 0, 1])
model = RandomForestClassifier()
model.fit(X, y)
# 新的数据点
new_data = np.array([[2, 3]])
prediction = model.predict(new_data)
print(f"Prediction: {prediction[0]}")
通信与网络模块
负责不同设备之间的通信,包括跨平台和异构设备的互联互通。 代码实现应包含协议转换、数据加密和传输优化等。
import socket
def start_server():
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.bind(('localhost', 12345))
server_socket.listen(5)
print('Server started, waiting for connections...')
while True:
client_socket, addr = server_socket.accept()
print(f"Connection from {addr}")
client_socket.send(b'Hello from server!')
client_socket.close()
if __name__ == "__main__":
start_server()
界面与用户交互模块
为用户提供友好的界面,展示系统状态和数据分析结果。 代码实现可以使用Web前端框架,如React或Vue,结合后台API。
// 使用React创建简单的前端界面
import React, { useState } from 'react';
function App() {
const [message, setMessage] = useState('');
const fetchData = async () => {
const response = await fetch('http://localhost:5000/api/data');
const data = await response.json();
setMessage(data.message);
};
return (
<div>
智能社区管理系统
<button onClick={fetchData}>获取数据</button>
<p>{message}</p>
</div>
);
}
export default App;
系统容错与恢复模块
处理系统异常、数据恢复和故障容错机制。 代码实现需要考虑日志记录、自动故障恢复等机制。
import logging
logging.basicConfig(filename='system.log', level=logging.DEBUG)
def process_data(data):
try:
# 模拟数据处理
result = data / 0
return result
except ZeroDivisionError as e:
logging.error(f"Error processing data: {e}")
# 实现简单的故障恢复机制
return None
if __name__ == "__main__":
data = 100
result = process_data(data)
if result is None:
print("Failed to process data, check logs for details.")
else:
print(f"Processed data: {result}")
