At least one embodiment of the present disclosure provides a wearable device, which may be a hybrid pointer watch, with both physical pointers 101 and an electronic display. Referring to fig. 1 and 2, examples of structural schematic diagrams of a wearable device are shown, including: a physical pointer 101; at least one sensor 102 for collecting interference data at a first frequency, the interference data including at least one of magnetic field data and motion data; and the controller 103 is used for acquiring the interference data and controlling the rotation of the physical pointer 101 according to the interference data.
Wherein, wearable equipment can be for being provided with physics pointer 101's intelligent bracelet, intelligent wrist-watch etc. including wearable equipment main part and wrist strap. The physical pointer 101 is provided to a wearable apparatus main body having a dial 105, for example, and is visible from the outside, and the physical pointer 101 is provided on a front surface of the dial 105 of the wearable apparatus main body. The physical pointer 101 can be timed by rotating, and different positions in the rotating process can correspond to different times, for example, a dial 105 has a time scale, and the position of the physical pointer 101 is a position relative to the time scale.
At least one sensor 102 may be disposed within the wearable device body, and when there is a dial 105, may be disposed on the back of the dial 105. Each sensor 102 is configured to collect at least one item of interference data, where each item of interference data is used to characterize the operation stability of the wearable device on the one hand, and the operation stability of the wearable device can directly affect the rotation of the physical pointer 101, that is, if any one item of interference data is abnormal, the operation stability on the other hand will be poor, and then the rotation of the physical pointer 101 will be affected. The interference data may include at least one of magnetic field data and motion data, and may also include other types of data. The magnetic field data can represent whether magnetic field interference exists in the environment where the wearable device is located, the motion data can represent whether the wearable device is subjected to mechanical interference, other types of data can also represent one or more types of interference, and the interference exists in a single interference scene or a common interference scene.
A controller 103 is disposed in the wearable device body and electrically connected to each sensor 102, and the controller 103 may be a dedicated controller 103 for acquiring the interference data collected by at least one sensor 102, or may be a main controller 103 of the wearable device. The controller 103 controls the operation of the physical pointer 101, and may control the rotation or stop of the physical pointer 101, the speed of rotation, and the like.
A movement 104 formed by a stepping motor and/or a gear transmission mechanism and the like can be further arranged in the wearable device main body, and the movement 104 can drive the physical pointer 101 to rotate; the controller 103 is electrically connected with the movement 104, and can control the movement 104 to drive the physical pointer 101 to rotate, so that the angle, direction and speed of rotation of the physical pointer 101 can be accurately controlled.
In addition, other electrical components such as a battery, a main board, a clock unit and the like are arranged in the wearable equipment main body.
In the wearable device in the embodiment of the present disclosure, the at least one sensor 102 collects interference data including at least one of magnetic field data and motion data, so that the controller 103 can acquire the interference data and control the rotation of the physical pointer 101 according to the interference data, which is beneficial to avoiding the influence of interference on the physical pointer, and thus the rotation accuracy of the physical pointer 101 can be improved.
In some embodiments of the present disclosure, the at least one sensor 102 includes a geomagnetic sensor and a motion sensor.
The geomagnetic sensor may acquire magnetic field data, and the acquired magnetic field data may be an individual earth magnetic field or a composite magnetic field obtained by superimposing the earth magnetic field with other magnetic fields. The magnetic field other than the earth magnetic field may form an interference magnetic field, that is, the magnetic field generated by the stator coil of the stepping motor itself may be interfered, which may cause the driving force of the stepping motor to be insufficient, cause the movement 104 to rotate abnormally, and further cause the physical pointer 101 to stop rotating or lose steps. Therefore, magnetic field data acquired by the geomagnetic sensor can represent whether an interference magnetic field exists in the environment where the wearable device is located, and if the interference magnetic field exists, the operation of the physical pointer 101 may be affected, so that the timing accuracy is affected.
Wherein the motion sensor may collect motion data, for example, the motion sensor may be an acceleration sensor 102 and/or a gyroscope. Wearable equipment can adapt to the motion of a certain degree, that is to say, motion within a certain degree, and wearable equipment's operating stability is not influenced, and physical pointer 101 can normal operating. However, when the wearable device is subjected to violent movements such as impact, an excessive acceleration may affect the gear transmission structure to cause abnormality (that is, when the impact force is large, the driving force output by the stepping motor cannot meet the requirement of the gear transmission), and the abnormal rotation of the pole piece will directly affect the operation stability of the physical pointer 101, resulting in inaccurate timing. Therefore, the motion data collected by the motion sensor may represent an external force applied to the wearable device, and if the external force is large, the operation of the physical pointer 101 may be affected, thereby affecting the accuracy.
One or more sensors 102 may be provided for each type, and when a plurality of sensors are provided, the collected interference data may be summarized and processed, for example, by taking a maximum value, averaging, and the like, to be used as an effective value of the interference data.
In some embodiments of the present disclosure, the controller 103 may control the rotation of the physical pointer 101 in the following manner: in response to that a first interference data in the interference data meets a rotation interference condition, controlling the physical pointer 101 to stop rotating, and the at least one sensor to continue to collect interference data; and controlling the physical pointer to rotate from a stop position for stopping rotation to a target position in response to second interference data in the interference data meeting an interference elimination condition.
The first interference data may be interference data at a certain time, and the second interference data may be interference data at another time after the first interference data. Therefore, the types of data included in the first interference data and the second interference data are the same, and the judgment condition of each item of data may be the same or different.
A safety threshold corresponding to each item of data of the interference data can be preset, and when at least one item of data in the interference data exceeds the corresponding safety threshold, the interference data is judged to meet the rotation interference condition. That is, when any item of the interference data exceeds the corresponding safety threshold, the operation stability of the wearable device is affected, and thus the rotation of the physical pointer 101 can be stopped, thereby avoiding inaccurate rotation of the physical pointer 101. For example, the disturbance data includes both magnetic field data and motion data, and when the magnetic field data exceeds a safety threshold of the magnetic field, there may be magnetic field disturbance, thus stopping the rotation of the physical pointer 101; when the motion data exceeds the safety threshold of acceleration, there may be an impact force disturbance, thus stopping the rotation of physical pointer 101; when both the magnetic field data and the motion data exceed the respective safety thresholds, there may be both magnetic field interference and impact force interference, thus stopping the rotation of physical pointer 101.
A safety threshold corresponding to each type of interference data may be preset, and when each item of data in the interference data is kept within the corresponding safety threshold within a preset time period, it is determined that the interference data satisfies an interference cancellation condition. That is, when the duration that each item of the interference data is kept within the corresponding safety threshold is greater than or equal to the preset duration (for example, 3s), the operation stability of the wearable device does not have any interference, and thus the normal rotation of the physical pointer 101 can be resumed, where the normal rotation includes first controlling the physical pointer 101 to rotate from the position where the rotation is stopped to the position corresponding to the standard time (i.e., the target position), and then controlling the physical pointer 101 to continue to rotate in the normal timing mode.
In addition, when each item of interference data is kept within the corresponding safety threshold during the normal rotation of the physical pointer 101 in the timing mode, the physical pointer 101 is controlled to continue to rotate in the timing mode.
In this embodiment, when controlling the physical pointer 101 to move from the stop position of stopping rotation to the target position, the duration of stopping rotation of the physical pointer may be determined first, and then the target position of the physical pointer 101 may be determined according to the duration of stopping rotation of the physical pointer 101, the calibration rotation speed of the physical pointer 101, and the timing rotation speed of the physical pointer, where the target position refers to a position corresponding to the standard time (the time of stopping correction, that is, the time of completing correction).
Further, the calibration time of the physical pointer may be determined according to the duration of the physical pointer stopping rotation, the calibration rotation speed of the physical pointer, and the timing rotation speed of the physical pointer, and then the target position of the physical pointer may be determined based on the calibration time of the physical pointer and the duration of the physical pointer stopping rotation. The calibration elapsed time refers to the time required for the physical pointer to rotate from the stop position to the target position at the calibration rotation speed, and may be calculated by using the following formula: delta T1＝ωa*(T2-T1)/ωbWherein, Δ T1To calibrate time, ωaFor timing speed, ωbFor the calibration of the speed, T2 is the time at this time, T1 is the time when the physical pointer 101 stops rotating, (T2-T1) is the duration of the stop of the rotation of the physical pointer 101. When determining the target position, the compensation time Δ T from the start time of stopping the rotation to the target position may be calculated as Δ T according to the following formula1+ (T2-T1), and then controls the physical pointer 101 to rotate at the calibrated speed for a compensation time Δ T starting from the position where the rotation is stopped, and to reach the target position. I.e. compensates for the duration of time the physical pointer 101 stops rotating and the number of steps lost in correcting the elapsed time.
Wherein the wearable device may have a timer, and the timer starts timing in response to a first interference data of the interference data satisfying the rotation interference condition, and stops timing in response to a second interference data of the interference data satisfying the interference cancellation condition, for example, a timing result when the physical pointer 101 stops moving is T1, and a timing result when the timing is stopped is T2. The controller 103 can thus acquire the duration of the stop motion of the physical pointer 101 from the timer.
The wearable device may have a clock unit for recording a standard time. The controller may thus record a first time T1 of the clock unit in response to a first one of the disturbance data satisfying a rotational disturbance condition and a second time T2 of the clock unit in response to a second one of the disturbance data satisfying a disturbance cancellation condition, and finally determine an interval T2-T1 between the first time and the second time as a duration of the physical hand stopping rotation.
In some embodiments, the clock Unit, the timer, and the controller 103 may be integrated into a processor of the wearable device, such as a Microcontroller Unit (MCU).
In addition, the controller 103 may control the acquisition frequency of each sensor 102. When each sensor 102 rotates in the timing mode, corresponding interference data can be acquired according to a first frequency, and when the first interference data in the interference data meets a rotation interference condition, each sensor is controlled to acquire corresponding interference data according to a second frequency, that is, when the physical pointer stops rotating, the interference data is acquired according to the second frequency; wherein the second frequency is higher than the first frequency. That is, when there is some disturbance in one or more aspects and the physical pointer 101 is controlled to stop rotating, the collection frequency of the sensor 102 in one or more aspects may be increased, so that the elimination time of the disturbance in one or more aspects may be determined more accurately, the duration of the stop of the physical pointer 101 may be shortened, and the effectiveness of the operation may be improved.
In one example, the physical hands 101 include an hour hand, a minute hand, and a second hand, and the hour hand, the minute hand, and the second hand sequentially increase in length and decrease in width. Therefore, when the controller 103 controls the physical hand 101 to stop rotating, the hour hand, the minute hand, and the second hand can be controlled to stop rotating synchronously, and when the physical hand 101 is controlled to rotate at the standard position, the hour hand, the minute hand, and the second hand are controlled to rotate at the respective corresponding standard positions.
In this embodiment, the controller 103 acquires interference data acquired by each sensor 102 in real time, and determines whether each kind of interference data is within a safety range in real time, and if each kind of interference data is within the safety range, controls the physical pointer 101 to normally rotate in a timing mode (i.e., at a timing speed) to perform timing; when any interference data exceeds the safety range, the operation stability of the wearable device is interfered, inaccurate rotation caused by continuous rotation of the physical pointer 101 is avoided, the rotation of the physical pointer 101 is stopped immediately, whether each interference data is in the safety range or not is continuously judged in real time, if any interference data exceeds the safety range, the rotation of the physical pointer 101 is continuously stopped, and when each interference data is in the safety range, the interference data exceeding the safety range is judged to be recovered to be normal (or recovered to be safe), namely the interference of the operation stability of the wearable device is eliminated, so that the rotation of the physical pointer 101 can be recovered in time, the compensation time is determined, the target position is reached after the compensation time is rotated at the calibration speed, and the normal timing is immediately performed at the timing speed, namely the normal timing is recovered. Therefore, when wearable equipment receives the interference, the automatic detection and calibration of the interference can be realized without manual adjustment of a user or sending of an automatic calibration instruction, the detection and elimination of the interference are realized, the anti-interference capability of the wearable equipment and the accuracy of time indication are improved, and the user experience is improved.
