中断里设置事件集接收不到

请问为什么这么做接收不到事件？
整个程序用Cube MX搭建
配置PE1为外部中断EXTI重写回调函数
void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin)
{
	if(GPIO_Pin == sen_door_Pin)
	{
		rt_event_send(&rt_event_sensor, SENSOR_DOOR_OPEN);
	}
}

在主函数main.c里
struct rt_event rt_event_sensor;
main()
{
 //初始化事件
    rt_event_init(&rt_event_sensor, "Sensorevent", RT_IPC_FLAG_FIFO);
 //创建一条线程
    sensor_thread = 
    rt_thread_create( "sensor",
                      sensor_thread_entry,
                      RT_NULL,
                      1024,
                      3,
                      15);

if (sensor_thread != RT_NULL)
       rt_thread_startup(sensor_thread);
   else
       return -1;
}
//线程回调函数
static void sensor_thread_entry(void* parameter)
{
	rt_uint32_t e;
	while(1)
	{
#if 1
		if(rt_event_recv(&rt_event_sensor, (SENSOR_DOOR_OPEN),
                     RT_EVENT_FLAG_OR | RT_EVENT_FLAG_CLEAR,
                     RT_WAITING_FOREVER, &e) == RT_EOK)
		{
			switch(e)
			{
				case SENSOR_DOOR_OPEN:
					//rt_thread_mdelay(50);
					LED_RED_ON;
					break;
				case SENSOR_BLOCK:
					break;
				case SENSOR_BUBBLE:
					break;
				default:
					break;
			}
		}
#endif
	}
}

这个灯死活不亮 测试过如果直接写在IO中断回调函数里，灯就亮了
