Question

在我的覆盆子pi上，我正在运行一个时间推移相机，而不是它保存到USB闪存驱动器，它已经工作正常，直到几天前。当我启动它时，它将运行，打印出所拍摄的照片数量，然后重复，这是正常的，但现在它会这样做，然后停止。过了一会儿，它会冻结并停止一切。我无法通过远程桌面连接等连接到它，但奇怪的是我仍然可以访问它托管的网站。这是代码：

#!/usr/bin/env python


import time
import picamera
import RPi.GPIO as GPIO
from subprocess import call
from datetime import datetime
import math


green = 16 #Running 
red = 20 #wating for sunset
startProgram = 21 #button to start every thing


GPIO.setmode(GPIO.BCM)
GPIO.setup(17, GPIO.IN, GPIO.PUD_UP) #push button
GPIO.setup(green, GPIO.OUT)
GPIO.setup(red, GPIO.OUT)


d = datetime.now()
initYear = "%04d" % (d.year) 
initMonth = "%02d" % (d.month) 
initDate = "%02d" % (d.day)
initSec = "%02s" % (d.second)

GPIO.setmode(GPIO.BCM)
GPIO.setup(17, GPIO.IN, GPIO.PUD_UP) #push button
GPIO.setup(green, GPIO.OUT)
GPIO.setup(red, GPIO.OUT)

folderToSave = "timelapse_" + str(initYear) + "_" + str(initMonth) + "_" +  str(initDate) + "_" + str(initSec) + "/"
folderToSave2 = "timelapse_" + str(initYear) + "_" + str(initMonth) + "_" +  str(initDate) + "_" + str(initSec) + "/"
os.mkdir(folderToSave)


var = 1
while var == 1 :  # This constructs an infinite loop
    with picamera.PiCamera() as camera:
        i =datetime.now()                   #what time is it
        now = i.strftime('%Y%m%d-%H%M%S')   #how to format the time
        photo_name = now + '.jpg'           #what the photo will be called
        camera.resolution = (1920, 1080)
        camera.led = 0

        GPIO.output(red, GPIO.LOW)
        GPIO.output(green, GPIO.HIGH)
        camera.capture(folderToSave + photo_name) #takes the photo to the lochal disk
        camera.capture(folderToSave2 + photo_name) #takes the photo to the lochal disk
        GPIO.output(green, GPIO.LOW)
        GPIO.output(red, GPIO.HIGH)


        time.sleep(10)

感谢您的帮助

这里还有一个相机曝光器，可以工作约3秒钟，然后冻结同样的问题
