基于 GPIO 輸入和時間的 Python rpi GPIO 輸出控制

我正在嘗試編寫一個小腳本來根據兩個因素控制兩個樹莓派的 GPIO 輸出引腳：GPIO.input.17 的狀態和一天中的時間。當 gpio.input.17 為低電平時，我希望 gpio.output.23 和 gpio.output.25 為低電平。我希望當 gpio.input.17 為高且時間在 0700-2159 之間時 gpio.output.23 變高。我希望當 gpio.input.17 為高且時間在 2200-0659 之間時 gpio.output.25 變高。到目前為止，我整理的代碼如下所示：#!/usr/bin/pythonimport timeimport RPi.GPIO as GPIOGPIO.setwarnings(False)GPIO.setmode(GPIO.BCM)# Setup GPIO pinsGPIO.setup(17, GPIO.IN, pull_up_down=GPIO.PUD_DOWN) # set GPIO 17 as inputGPIO.setup(23, GPIO.OUT) # set GPIO 23 as outputGPIO.setup(25, GPIO.OUT) # set GPIO 25 as outputGPIO.output(23, 0) # set GPIO 23 as lowGPIO.output(25, 0) # set GPIO 25 as lowwhile True: dt = list(time.localtime()) hour = dt[3] minute = dt[4] second = dt[5] time.sleep(1) print hour,minute,second; PIR_Active = GPIO.input(17) if not PIR_Active: GPIO.output(23, 0) GPIO.output(25, 0) elif (PIR_Active and (hour>=00 and hour<=6) and (minute >=00 and minute<=59) and (second >=0 and second<=59)): GPIO.output(25, 1) elif (PIR_Active and (hour>=7 and hour<=11) and (minute>=0 and minute<=36) and (second>=0 and second<=59)): GPIO.output(23, 1) else: (PIR_Active and (hour>=11 and hour<=23) and (minute >=37 and minute<=59) and (second >=0 and second<=59)); GPIO.output(25, 1)time.sleep(1)GPIO.cleanup()我將 LED 連接到引腳 23 和 25，腳本中顯示的時間來自我的測試，我通過此代碼看到的結果是：Out.Pin 23 按照 In.Pin.17 的狀態在高電平和低電平之間切換，同時時間變量是真的Out.Pin 23 停止在高低之間切換，而時間變量不正確我感覺 Out.Pin.23 正在工作...當代碼執行時，Out.Pin 25 立即亮起，并且無論 In.Pin.17 的狀態或時間如何，都保持亮起。請忽略腳本中的時間，它們來自我的測試，與上述要求不符。我是編碼和編寫腳本的初學者，非常感謝社區的任何幫助。

雖然我可以在 IDLE 中運行它并遵循代碼中的邏輯，但我無法將其集成到我的腳本中（它破壞了我首先工作的內容：GPIO.output.23 遵循 GPIO.input.17 的狀態“在活動時間內”。

鑒于我的新手，你能指導我一下你的建議哪里出了問題嗎？我喜歡整理 if/elif 語句的想法。

#!/usr/bin/python

import time

import datetime as dt

import RPi.GPIO as GPIO

GPIO.setwarnings(False)

GPIO.setmode(GPIO.BCM)

# Define Time Variables

now = dt.datetime.now().time()

day = dt.time(16, 32, 59, 000000)

night = dt.time(16, 33, 00, 000000)

# Setup GPIO pins

GPIO.setup(17, GPIO.IN, pull_up_down=GPIO.PUD_DOWN) # set GPIO 17 as input

GPIO.setup(23, GPIO.OUT) # set GPIO 23 as output

GPIO.setup(25, GPIO.OUT) # set GPIO 25 as output

GPIO.output(23, 0) # set GPIO 23 as low

GPIO.output(25, 1) # set GPIO 25 as low

while True:

dt = list(time.localtime())

hour = dt[3]

minute = dt[4]

second = dt[5]

time.sleep(1)

print hour,minute,second;

PIR_Active = GPIO.input(17)

if not PIR_Active:

GPIO.output(23, 0)

GPIO.output(25, 0)

elif all([PIR_Active, day < now < night]):

GPIO.output(23, 1)

else: all([PIR_Active, day < now < night]);

GPIO.output(25, 1)

time.sleep(1)

GPIO.cleanup()

我已經設法解決了這個問題...我原來的 else 語句無效，因此我添加了第三個 elif 和我的“夜間”條件，并用將兩個 GPIO.out 引腳設置為 1 的 else 完成了該語句。

我還反轉了輸出的“靜止”狀態，因為我認為我得到的繼電器單元被應用了負值

這是帶注釋的工作代碼：

#!/usr/bin/python

import time

from time import sleep

import RPi.GPIO as GPIO

GPIO.setwarnings(False)

GPIO.setmode(GPIO.BCM)

# Setup GPIO pins

GPIO.setup(17, GPIO.IN, pull_up_down=GPIO.PUD_DOWN) # set GPIO 17 as input

GPIO.setup(23, GPIO.OUT) # set GPIO 23 as output

GPIO.setup(24, GPIO.OUT) # set GPIO 25 as output

GPIO.output(23, 1) # set GPIO 23 as high - relay boards are neg applied to activate, this keeps the relay powered off without a signal

GPIO.output(24, 1) # set GPIO 25 as high - relay boards are neg applied to activate, this keeps the relay powered off without a signal

while True:

dt = list(time.localtime())

hour = dt[3]

minute = dt[4]

second = dt[5]

time.sleep(.01) #The first time.sleep command value impacts any similar statements made below it

print hour,minute,second;

PIR_Active = GPIO.input(17) #Define a condition which is met in the statements below

if not PIR_Active: #If the input is not active, reset both outputs to 'off'

GPIO.output(23, 1)

GPIO.output(24, 1)

elif (PIR_Active and (hour>=00 and hour<=6) and (minute >=00 and minute<=59) and (second >=0 and second<=59)):

GPIO.output(24, 0) #If all of the above is true, set this output to on

time.sleep(30) #Hold this output 'on' for 30 seconds

elif (PIR_Active and (hour>=7 and hour<=21) and (minute>=0 and minute<=59) and (second>=0 and second<=59)):

GPIO.output(23, 0) #If all of the above is true, set this output to on

time.sleep(30) #Hold this output 'on' for 30 seconds

elif (PIR_Active and (hour>=22 and hour<=23) and (minute >=00 and minute<=59) and (second >=0 and second<=59)):

GPIO.output(24, 0) #If all of the above is true, set this output to on

time.sleep(30) #Hold this output 'on' for 30 seconds

else: #Cleanly exit out of the if/elif statements with an else that:

GPIO.output(23, 1) #Resets this output to 'off'

GPIO.output(24, 1) #Resets this output to 'off'

GPIO.cleanup()

首先，我承認這不是對你問題的完整答案，但對于評論來說太多了。

此部分答案的目的是建議簡化日期時間測試。

設定now時間
設定day時間
設定night時間
使用一個簡單的邏輯運算符來測試是白天還是晚上。

例子：

import datetime as dt

now = dt.datetime.now().time()

day = dt.time(7, 00)

night = dt.time(22, 00)

# Test if it's day time.

now

>>> datetime.time(14, 8, 6, 000000)

day < now < night

>>> True

# Test again at midnight.

now

>>> datetime.time(0, 0)

day < now < night

>>> False

將此邏輯集成到您的代碼中將有助于簡化if/elif,and語句。

例如，這個：

(PIR_Active and (hour>=00 and hour<=6) and (minute >=00 and minute<=59) and (second >=0 and second<=59))

...可以變成這樣 - 顯然使用你自己的時間定義。

all([PIR_Active, day < now < night])
