A Trouble Triggered by an Accident
“Oh dear, little bear, why do you look so glum?” Professor Rabbit hopped over to Little Bear.
“Sigh, don’t mention it!” Little Bear sighed, “Our factory’s panel production line has gone awry again! The workers are running around checking every link, but they still missed the temperature anomaly, resulting in a whole batch of panels being scrapped! This has really upset the boss…”
“Wow? With such a large production line, it’s really hard to keep everything under control!” Professor Rabbit stroked his chin, deep in thought.
Brilliant Plan Unveiled
Professor Rabbit’s eyes suddenly lit up: “Hehe, I have a great idea! Why don’t we use Python to create a ‘super eye’ to monitor it?”
“Huh? What’s that?” Little Bear tilted his head in confusion.
“It’s about connecting a bunch of small sensors with Python, placing them at key positions on the production line like sentinels. These little guys will monitor temperature, humidity, pressure, and other data 24/7, and immediately raise an alarm if there’s an anomaly. How cool is that!”
Code Implementation Revealed
“Wow! Teach me how to implement it!” Little Bear exclaimed eagerly.
“Come, come, come, let’s look at our magic code!” Professor Rabbit pulled out a magic notebook:
Python code snippet
import serial
import numpy as np
import matplotlib.pyplot as plt
from datetime import datetime
import threading
import queue
class SensorNetwork:
def __init__(self, port='COM3', baudrate=9600):
self.serial_port = serial.Serial(port, baudrate)
self.data_queue = queue.Queue()
self.is_running = True
def read_sensor(self):
while self.is_running:
if self.serial_port.in_waiting:
data = self.serial_port.readline().decode().strip()
timestamp = datetime.now()
self.data_queue.put((timestamp, float(data)))
def process_data(self, threshold=50):
while self.is_running:
if not self.data_queue.empty():
timestamp, value = self.data_queue.get()
if value > threshold:
self.trigger_alarm(value)
self.update_plot(timestamp, value)
def trigger_alarm(self, value):
print(f"Oh no! Anomaly detected: {value}! Come check it out!")
Real-World Adventure
“This is amazing!” Little Bear clapped his hands, “Let’s try it out!”
“Alright!” Professor Rabbit skillfully tapped on the keyboard:
Python code snippet
# Summon our monitoring little spirit
sensor_net = SensorNetwork()
# Launch the data collection squad
collector = threading.Thread(target=sensor_net.read_sensor)
processor = threading.Thread(target=sensor_net.process_data)
collector.start()
processor.start()
# Open the magic display
plt.ion()
plt.show()
“Look, those little dots are our monitoring data!” Professor Rabbit pointed at the bouncing curve on the screen, “Once there’s an anomaly, the system will ring to alert us!”
A Brighter Future Ahead
“Wow! With this magic tool, I won’t have to worry about missing inspections anymore!” Little Bear jumped up in excitement.
“Hehe, this is just the beginning!” Professor Rabbit winked mysteriously, “We can also teach it to predict failures, control remotely, and even automatically adjust production parameters! Python is like a treasure chest; as long as you can think of it, there’s no idea that can’t be realized!”
“Python is just amazing!” Little Bear said happily, “I need to hurry and tell the boss this good news!”
