进一步地，若在所述时间阈值T内，所述步进电机控制所述实体指针未完成所述调整量，则所述控制器从2按照自然数开始计数，每隔一个时间阈值T计数一次，且每隔一个时间阈值T所述调整量增加T；若所述步进电机控制所述实体指针完成增加后的调整量时所述计数的计数值为N，则所述控制器控制所述实体指针停止转动，直到所述控制器计时到第N个时间阈值T（即NT的时间），所述实体指针再次开始转动。Further, if the stepping motor controls the entity pointer to not complete the adjustment amount within the time threshold T, the controller starts counting from 2 according to the natural number, and counts every other time threshold T. And the adjustment amount is increased by T every other time threshold T; if the stepping motor controls the physical pointer to complete the increased adjustment amount, the count value of the count is N, then the controller controls the entity The pointer stops rotating until the controller counts to the Nth time threshold T (i.e., the time of NT), and the physical pointer begins to rotate again.
下面通过实施例描述该系统的运行：The operation of the system is described below by way of an embodiment:
实施例1：Example 1:
利用手机的图像分析软件对手表的表盘进行拍照，该图像分析软件除了获取表盘的图像外，同时记录拍照的实际时间t1，如t1为5时3分20秒，并将该实际时间t1存储在手机的存储模块中。Using the image analysis software of the mobile phone to take a picture of the watch's dial, the image analysis software not only acquires the image of the dial, but also records the actual time t1 of the photograph, such as t1 is 5:3:20, and stores the actual time t1 in In the storage module of the phone.
图像分析软件对获取的图像进行分析，得出表盘的显示时间t2，如t2为5时2分55秒，并该该显示时间t2存储在所述手机的存储模块中。The image analysis software analyzes the acquired image to obtain a display time t2 of the dial, such as t2 is 5:2:55, and the display time t2 is stored in the storage module of the mobile phone.
所述图像分析软件计算时间差Δt=t1-t2=25秒。The image analysis software calculates the time difference Δt=t1-t2=25 seconds.
手机通过无线通讯模块将该时间差25s传输至手表，手表的控制器接收到该时间差后，对指针进行调整，并同时开始从0计时。控制器中存储时间阈值T=30秒，那么调整量为Δt+T，即55s，55s为正值，那么将表盘指针向前（顺时针）旋转55s。The mobile phone transmits the time difference of 25s to the watch through the wireless communication module, and after receiving the time difference, the controller of the watch adjusts the pointer and starts timing from 0 at the same time. The controller stores the time threshold T=30 seconds, then the adjustment amount is Δt+T, that is, 55s, 55s is positive value, then the dial pointer is rotated forward (clockwise) for 55s.
当调整完毕时，若上述从0计时的时间在所述时间阈值30s内，则控制器控制指针停止旋转，直至所述计时达到所述时间阈值T。When the adjustment is completed, if the time counted from 0 is within the time threshold 30s, the controller controls the pointer to stop rotating until the timing reaches the time threshold T.
实施例2：Example 2:
利用手机的图像分析软件对手表的表盘进行拍照，该图像分析软件除了获取表盘的图像外，同时记录拍照的实际时间t1，如t1为5时3分20秒，并将该实际时间t1存储在手机的存储模块中。Using the image analysis software of the mobile phone to take a picture of the watch's dial, the image analysis software not only acquires the image of the dial, but also records the actual time t1 of the photograph, such as t1 is 5:3:20, and stores the actual time t1 in In the storage module of the phone.
图像分析软件对获取的图像进行分析，得出表盘的显示时间t2，如t2为5时5分20秒，并该该显示时间t2存储在所述手机的存储模块中。The image analysis software analyzes the acquired image to obtain a display time t2 of the dial, such as t2 is 5:5:20, and the display time t2 is stored in the storage module of the mobile phone.
所述图像分析软件计算时间差Δt=t1-t2=-120秒。The image analysis software calculates the time difference Δt=t1-t2=-120 seconds.
手机通过无线通讯模块将该时间差25s传输至手表，手表的控制器接收到该时间差后，对指针进行调整，并同时开始从0计时。控制器中存储时间阈值T=30秒，那么调整量为Δt+T，即-90s，-90s为负值，那么将表盘指针向后（逆时针）旋转90s。The mobile phone transmits the time difference of 25s to the watch through the wireless communication module, and after receiving the time difference, the controller of the watch adjusts the pointer and starts timing from 0 at the same time. The controller stores the time threshold T=30 seconds, then the adjustment amount is Δt+T, that is, -90s, and -90s is negative, then the dial pointer is rotated backward (counterclockwise) for 90s.
若计时器从0计时到30s，仍然未调整完璧，则所述控制器启动所述计数器从2按照自然数开始计数，每隔一个时间阈值T计数一次，且每隔一个时间阈值T所述调整量增加30s，若计数器计数值为5时，调整完毕，此时的调整量为-120s+5*30=30，即最后的实际调整量为30s。调整完后，控制器控制指针停止，直至所述计时到5*30s=150s，控制器再控制指针继续旋转。If the timer has not been adjusted from 0 to 30 s, the controller starts to start counting from 2 according to the natural number, every other time threshold T, and every other time threshold T Increase 30s, if the counter count value is 5, the adjustment is completed, the adjustment amount at this time is -120s+5*30=30, that is, the last actual adjustment amount is 30s. After the adjustment, the controller controls the pointer to stop until the timing reaches 5*30s=150s, and the controller then controls the pointer to continue to rotate.
