Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Referring to fig. 1, a schematic block diagram of a control circuit for auto-calibration of a pointer according to an embodiment of the present application shows only parts related to the embodiment for convenience of description, and the following details are described:

The sensing module 102 is connected to the pointer, and is configured to acquire a real-time position of the pointer every preset time period, and output a feedback signal.
Specifically, the connection mode of the sensing module 102 and the pointer is close-range connection, and the close-range connection can be performed through media such as a magnetic field, an electric field, and a sound field, and the real-time position of the pointer is detected. As is well known, the real-time position of the pointer is converted into a real-time which can be seen by human eyes, so that the real-time indicated at present can be known clearly only by knowing the real-time position of the pointer. The real-time position of the pointer is detected at intervals of a preset time period, so that the pointer is positioned at intervals of a time period, and can be calibrated in time when the deviation is large, the experience of a user is improved, and unnecessary troubles caused by delay due to inaccurate time are avoided. The preset time period can be set according to specific requirements; in this embodiment, a magnet representing a reference origin (which may be multiple reference origins) is mounted on the wheel disc of the gear, the magnetic control switch assembly is mounted at a standard position where the magnet passes through, and the time that the magnetic control switch assembly conducts and outputs the feedback signal after the wheel disc rotates once, that is, the magnet is adjacent to the magnet twice, is a preset time period.
Meanwhile, the hands comprise an hour hand, a minute hand and a second hand, and of course, only the hour hand or only the hour hand and the minute hand can be arranged according to the requirement.
And the main control module 101 is connected with the sensing module 102 and is used for receiving the feedback signal, confirming the positioning position of the pointer according to the feedback signal, and outputting a driving signal according to a specified algorithm when the difference value between the real-time displayed by the pointer and the standard time of the location of the pointer exceeds a preset threshold value.
Specifically, the main control module 101 has a database stored in advance, and the time in the database is standard time of the location, including china time (beijing time), american time, british time, and the like. When the main control module 101 receives the feedback signal, the positioning position of the pointer is firstly confirmed according to the feedback time, so as to obtain the real-time, meanwhile, the standard time of the location is called, and the real-time displayed by the pointer is compared with the standard time of the location. If the difference value between the real-time and the standard time of the location exceeds the preset threshold, for example, the preset threshold is defined as 1 minute, the standard time of the location is 14:15:00, the real-time displayed by the pointer at the moment is earlier than 14:14:00 or later than 14:16:00, and the main control module 101 determines that the difference value between the real-time displayed by the pointer and the standard time of the location exceeds the preset threshold, outputs a driving signal to the driving module 103.
And the driving module 102 is connected with the main control module 101 and is used for performing power amplification on the driving signal and correcting the real-time position of the pointer so as to enable the real-time displayed by the pointer to be consistent with the standard time of the location.
