Embodiment 1
The purpose of the present embodiment is that illustrating prior art problem and resolving ideas of the invention.
The clock and watch of pointer-type, mistake when being easy the interference by outside and the structure for driving pointer generation variation being caused to cause to walk
Difference, the present embodiment provides a kind of methods of reduction walking time error as shown in Figure 1, suitable for controlling pointer by drive waveforms

Time set includes the structures such as MCU, pointer, gear-box, magnetometric sensor and acceleration transducer, acceleration sensing
Device is also used to detect current wrist-watch whether by strenuous vibration, such as other than providing initial data for step counting, sleep scheduling algorithm
The amplitude or period for detecting vibration are greater than the threshold value for influencing normally to take the needle, then (MCU generates driving wave by stopping to master controller
Shape) it makes and stops needle operation, specifically, acceleration transducer can detect the acceleration information of wrist-watch, when wrist-watch is in acutely shake
In the case where dynamic, violent variation is presented in the data of three axis of acceleration information, and period of change is extremely short, and MCU passes through inspection
Current vibration period and vibration amplitude are surveyed, and carries out threshold value (interference threshold) comparison.Threshold value is the number tested when experiment
According to being obtained by test, which causes wrist-watch to take the needle, loses the threshold value of needle.When the acceleration value detected is greater than threshold value, being determined as can shadow
Sound takes the needle, and reminds user at this time and stops taking the needle, when the acceleration value to be checked measured is less than threshold value, restores to take the needle, and quickly
Needle is chased after, fills and stops the time of walking；Geomagnetic sensor is in addition to current for being also used to detect other than providing initial data for compass
Whether magnetic field environment, which influences whether, takes the needle, and when magnetic field strength, which influences, to take the needle, stops taking the needle, after leaving strong magnetic field circumstance, then
Recovery takes the needle and chases after needle, specifically, geomagnetic sensor can detect magnetic field strength, in the case that wrist-watch is in high-intensity magnetic field, ground
The data of three axis of Magnetic Sensor (i.e. magnetometric sensor) significantly increase, and MCU is carried out by detecting current magnetic field strength
Threshold value (interference threshold) comparison, threshold value are the data tested when experiment, and being obtained by test, which causes wrist-watch to take the needle, loses needle
Magnetic field strength threshold value, when the magnetic field strength detected is greater than threshold value, being determined as, which will affect, takes the needle, and reminds user at this time and stops
It takes the needle, when the field strength values to be checked measured are less than threshold value, restores to take the needle, and quickly chase after needle, fill and stop the time of walking；
MCU drives hand-manipulating of needle gear-box by pwm pulse wave, and the period speed of drive waveforms can control the speed to take the needle.Gear-box and
Pointer transmission connection, to make hour hands, minute hand, second hand rotation, in the environment of detecting high-intensity magnetic field and strenuous vibration, MCU stops
It only takes the needle, detects in the environment of leaving high-intensity magnetic field and strenuous vibration, MCU recovery takes the needle, and quickly chases after needle, will stop walking before
Step number fill.
Specific example:
The sensor threshold value that the precision that influences to take the needle is obtained by a large number of experiments stops the threshold taking the needle as judgement in program
Value, quickly shakes wrist-watch, observes that second hand takes the needle when the acceleration amplitude value of wrist-watch is 10000 or the vibration period is 100Hz
When lose needle, slow 2S, i.e. threshold value is acceleration amplitude value 10000, or vibration period 100Hz.By magnet close to wrist-watch, observe
When the range value of geomagnetic sensor is 5000, second hand stopping takes the needle, and slow 10S, geomagnetic sensor amplitude are less than after 10S
Restore to take the needle again after 5000, i.e., threshold value is geomagnetic sensor amplitude 5000.
In the control program of MCU, setting detection threshold value is acceleration amplitude value 10000, shakes period 100Hz, earth magnetism
Sensor range value 5000.And real-time sampling acceleration and geomagnetic data, and in real time and set threshold value comparison.
It was found that the range value of geomagnetic sensor has reached 6000, that is, it is more than set threshold value, will affect and take the needle, mistake when causing away
Difference.MCU controls motor vibration prompting user far from magnetic field at this time, and stops taking the needle, while being recorded in the time of magnetic field environment.
MCU continues to test environment, detects that magnetic field is 1000 after 10S, i.e., departing from strong magnetic field circumstance, MCU recovery takes the needle,
The wave period to be taken the needle by accelerating driving, the time of 10S has been walked in 1S, that is, has been restored to normal time.It at this time will be
The uncertain number that takes the needle in magnetic field environment is supplied, and walking time error is avoided.
Embodiment 2
The purpose of the present embodiment is that illustrating preferred embodiment.
More satisfactory disposition described in embodiment 1, in fact, the variation of acceleration and magnetic force will more without
Sequence, therefore the environment (acceleration and/or magnetic force change influence pointer) that will appear a period of time appearance when influencing, a period of time
Restore normal afterwards, then proceedes to situations such as abnormal.
In view of these situations, propose corresponding solution, when occur it is abnormal (i.e. as described in above-described embodiment, because
Pointer is influenced for acceleration and/or magnetic force to operate normally), normal situation when, i.e., it is abnormal only to occur primary (considering big portion
Divide the living environment of people, this situation is also to have sizable possibility), then normally execute method described in embodiment 1.
It is abnormal (i.e. as described in above-described embodiment, because acceleration and/or magnetic force influence pointer are normally transported when occurring
Row), it is normal, abnormal when, then need to judge normal time whether long enough because acceleration transducer and magnetometric sensor are always
Deposit error, it is difficult to guarantee absolutely accurate, while consider extreme situation, also it should be ensured that clock and watch are not because normal, abnormal
Short time occurs repeatedly and calculating/execution of compensation variable is caused exception occur, therefore proposes " using end time as starting point, to arrive
Occur the period that interference parameter is greater than preset interference threshold, marking it for interval time again, it is big when the interval time
In preset time threshold ", the purpose is to establishments of a mechanism, i.e., if second of the abnormal interval normally arrived is too short, recognize
For and there is no normal (i.e. this is normally error), whole error judgment is advantageously reduced, while improving method execution
Stability.
It is abnormal (i.e. as described in above-described embodiment, because acceleration and/or magnetic force influence pointer are normal when occurring first
Operation), when first normal, second abnormal, third is abnormal, second normal, the 4th is abnormal, based on above-mentioned example, it is known that for
Reduce whole error judgment, while improving the purpose of the stability of method execution, can by it is a part of it is normal (i.e. acceleration,
Magnetic force is less than threshold value) example be considered as in vain, then at the time of needing to establish new normal again, judgment criteria i.e. second is normally
Time between moment and the 4th exception has to be greater than interference threshold, the purpose is to establish a kind of process circulation, improves
The stability that method executes.
In addition, people will not pay close attention to always wrist-watch, and correspondingly, the acceleration change and magnetic force change of pointer can be influenced
Change is not that human body can be perceived normally, and therefore, for the purpose of prompting, wrist-watch can export sound and light signal and vibrating alert
Signal, sound only needs to be provided with the memory of storing data and loudspeaker were both able to achieve, optical signal only need LED (i.e. light source,
Can be other light emitting components) it can be realized as, vibration can refer to mobile phone, and a vibrator, relevant auxiliary electricity is arranged
Road is also known in industry, and the present embodiment is without further instruction.
