Question

你好，我讨厌到这里结束，但是我自己不能解决这个问题。

我已经使用tkinter for UI运行了python脚本。它已连接到蓝牙设备和wifi插头。 BT提供温度和湿度，一旦达到一定的温度/湿度值，插头就会打开抽气功能。不幸的是，有时BT设备会给出NoneType值，或者无法连接到wifi插头。因此，脚本崩溃。我已经设置了一个bash脚本，该脚本会自动重新启动python脚本，但这似乎并没有更新tkinter窗口并使它重新运行！我该如何实现？谢谢！

def UI():
    b = BeewiSmartClimPoller("F0:C7:7F:85:B4:79")
    time_day = dt.datetime.now().strftime('%H:%M:%S')
    temp_c = b.get_temperature()
    humidity = b.get_humidity()
    b.update_sensor()
    env = [temp_c, humidity, time_day]
    env_exp.append(env)
    df = pd.DataFrame(env_exp)
    df.to_csv ('/home/pi/env_export.csv', index = False, header=['Temp', 'H', 'Time'])
    temp = (temp_c,'°C')
    hum = (humidity,'%')
    if temp_c > 25 or humidity > 48:
        plug_temp.turn_on()

    else:
        plug_temp.turn_off()

    lab_text.config(text = 'Time')
    lab.config(text = time_day)
    lab_h_text.config(text = 'Humidity')
    lab_h.config(text = hum)
    lab_t_text.config(text = 'Temperature')
    lab_t.config(text = temp)
    lab_plug_text.config(text = 'Status')
    if plug_temp.state == 'ON':
        lab_plug.config(image = img_on)  
    else:
        lab_plug.config(image = img_off)

    window.after(120000, UI)

UI()
window.mainloop()

和bash代码：

until python3 flowerbeewi.py; do
 echo "Crashed with exit code $?/ restarting..." >&2
 sleep 3
done

自动重启python和新的tkinter窗口
