这个错误可能是因为 subprocess.Popen() 方法返回的对象类型不是 Process 类型，而是 NoneType 类型。这可能是由于 subprocess.Popen() 调用失败导致的。

你可以在调用 subprocess.Popen() 方法之前添加一些错误处理代码，以避免此错误。例如：

while True:
    try:
        proc = subprocess.Popen(["python3", "/home/pi/Documents/8-17/simplest.py"])
        break
    except Exception as e:
        print("Error starting process:", e)
        time.sleep(1)

while proc.poll() is None:
    time.sleep(1)
    print("simplest运行中.....")
    chinanet = isNetChainOK()
    if chinanet is False:
        print("网络异常")
        for proc in psutil.process_iter():
            if proc.name() == 'simplest.py':
                print("simplest受网络问题强行中断")
                proc.terminate()  # or proc.kill()
                proc = subprocess.Popen(["python3", "/home/pi/Documents/8-17/simplest.py"])
        getNet()

这样，如果 subprocess.Popen() 调用失败，代码将等待 1 秒钟，然后重试。如果调用成功，代码将继续执行。
