У меня есть сценарий Python для установки в художественном музее, который предназначен для непрерывного воспроизведения звуков, управления светодиодной матрицей и восприятия людей с помощью OpennCV и тепловой камеры.
Каждая из частейскрипт работает, и все они работают вместе, но случайным образом скрипт блокируется, и мне нужно перезапустить его.Я хочу, чтобы сценарий не блокировался, поэтому никто не должен сбрасывать его во время выставки.
У меня есть код, работающий на запасном Raspberry Pi и запасной светодиодной матрице, и он продолжает нормально работать.Единственными изменениями, которые я сделал, были закомментирование начала потока для проверки ИК-датчика и вызов функции для получения максимальной температуры от датчика.
Чтобы было ясно, если я оставлю эти битыкод в скрипте работает нормально 1 -3, а иногда и 10 раз.Но кажется, что он блокируется в первом «состоянии», когда IRcount = 0
Я застрял.Будем благодарны за любую помощь.

Обновление 1 - Подозреваемые функции
Когда я оставил сценарий, запустился всю ночь и пришел на выставку утромон застрянет в 1-м состоянии IRcount = 0 Единственное, что происходит в этом состоянии - это функция maxTemp() для получения максимальной температуры, функция очистки цвета светодиодом для циклического изменения цветов.
Когда я придуутром он застревает, проигрывая один звук из пигмеи, как и должно быть, но это не будут циклические цвета.Я удалил maxTemp() из моего тестового Pi, и он работал нормально.
def maxTemp():
mlx.setup(8) #set frame rate of MLX90640
f = mlx.get_frame()
mlx.cleanup()
# get max and min temps from sensor
# v_min = min(f)
v_max = int(max(f))
return v_max
Обновление # 2
Я думал, что проблема может быть в потокепоэтому я закомментировал начальный вызов потока.Вот почему я сделал более простую функцию maxTemp(), чтобы посмотреть, будет ли она работать лучше, чем поток.Поэтому, когда я использовал максимальную температуру, поток не вызывался.
Я не очень хорошо понимаю темы.Можно ли постоянно обновлять переменную max temp и постоянно выполнять простые манипуляции OpenCV numPy?Это было бы идеально.Когда я первоначально добавил поток, он, казалось, прекратился через несколько циклов.
У меня нет соединения в теме.Я знаю, что потоки не "перезапускаются", но нужно ли мне вызывать его снова, когда конечный автомат запускается снова?
# not currently starting the thread because program is locking up without it
# want to figure out initial problem first
#start thread
#task = TempTask()
#task.start()
Обновление # 3
I Загруженоновый код, устраняющий дублирующиеся функции.Все обрабатывается в потоке temp.task сейчас.Кажется, это работает нормально.Я также поместил предложение github опроса термодатчика, если изображение дублируется, но этого не произошло.
Я оставил программу запущенной на ночь, а когда зашел утром, она была заблокирована.SD-карта установлена в режим только для чтения.Я ssh'd в пи.У меня есть скрипт автоматического запуска Python в /etc/profile Кажется, что запускать скрипт каждый раз, когда я захожу в ssh.Когда я вошел в систему этим утром, чтобы посмотреть, был ли пи до сих пор, он выдает ошибку нехватки памяти.
