基于树莓派的智能家居控制系统 1) 基本要求:配合各种传感器采集家里的环境信息,可以实现火灾报警、煤气泄露、雨滴检测、光照检测等一系列功能。当有火灾、煤气泄露发生时,相应的报警声音,光线弱式,能够打开照明灯。 2) 扩展要求:手机蓝牙通信,把报警信号发送给手机。请用python语言编程代码

以下是一个简单的基于树莓派的智能家居控制系统代码,实现了火灾报警、煤气泄露、雨滴检测和光照检测等功能,并且可以通过手机蓝牙通信将报警信号发送给手机:
```python
import RPi.GPIO as GPIO
import time
import bluetooth
GPIO.setmode(GPIO.BOARD)
# 火灾报警
GPIO.setup(3, GPIO.IN)
# 煤气泄露检测
GPIO.setup(5, GPIO.IN)
# 雨滴检测
GPIO.setup(7, GPIO.IN)
# 光照检测
GPIO.setup(11, GPIO.IN)
# 照明灯开关
GPIO.setup(13, GPIO.OUT)
# 蓝牙通信
server_sock = bluetooth.BluetoothSocket(bluetooth.RFCOMM)
port = 1
server_sock.bind(("", port))
server_sock.listen(1)
client_sock = None
client_info = None
def bluetooth_setup():
global client_sock, client_info
print("等待蓝牙连接...")
client_sock, client_info = server_sock.accept()
print("已连接:", client_info)
def bluetooth_send(message):
global client_sock, client_info
if client_sock is not None and client_info is not None:
client_sock.send(message)
def fire_alarm_callback(channel):
print("火灾报警触发")
GPIO.output(13, GPIO.HIGH)
bluetooth_send("火灾报警")
def gas_leak_callback(channel):
print("煤气泄露检测触发")
GPIO.output(13, GPIO.HIGH)
bluetooth_send("煤气泄露检测")
def rain_drop_callback(channel):
print("雨滴检测触发")
GPIO.output(13, GPIO.HIGH)
bluetooth_send("雨滴检测")
def light_sensor_callback(channel):
if GPIO.input(channel):
print("光照强")
else:
print("光照弱,打开照明灯")
GPIO.output(13, GPIO.HIGH)
bluetooth_send("光照弱")
GPIO.add_event_detect(3, GPIO.RISING, callback=fire_alarm_callback)
GPIO.add_event_detect(5, GPIO.RISING, callback=gas_leak_callback)
GPIO.add_event_detect(7, GPIO.RISING, callback=rain_drop_callback)
GPIO.add_event_detect(11, GPIO.BOTH, callback=light_sensor_callback)
bluetooth_setup()
try:
while True:
time.sleep(1)
except KeyboardInterrupt:
pass
GPIO.cleanup()
server_sock.close()
if client_sock is not None:
client_sock.close()
```
注释里面已经详细说明了每个部分的作用。需要注意的是,这只是一个简单的示例代码,实际应用中还需要考虑更多的情况和细节。
