After reading the rotation direction of lock core, just can further carry out record to the number of revolutions of lock core, thereby the rotation number of turns of lock core is judged.The number of times of record also derives from position sensor; Because the different number of turns that lock core rotates can have influence on the folding condition of door lock, such as rotating a circle realization, the lockset having locks, and therefore must instead turn around to realize and unblank; Some locksets rotates two circles and realizes and locking, and must rotate backward two circles and could realize and unblanking; So whether be rotated in place in order to determine accurately lock core, or whether in unblanking or locking state, just must carry out record to the number of times of lock core rotation, then in conjunction with setting position and the quantity of protruding key, the number of turns that just can rotate lock core judge accurately.For example in lock core rotating shaft, be provided with 2 protruding keys, these two protruding keys are straight line, angle is 180 degree, can determine position sensor and be triggered by these two protruding keys of difference, produce while stirring signal twice, lock core has rotated 180 degree, rotated half-turn, therefore, the number of times rotating by recording lock core, just can judge the degree that lock core rotates.
The direction of unblanking of lockset sets in advance by deploy switch, therefore, after reading the direction of rotation of lock core and rotating the number of turns, also need to read rotation direction configuration status, only have the configuration status in conjunction with rotation direction, just can accurately be to lock core in locking or unlocking condition judges.For example, deploy switch is set to be rotated counterclockwise and unblanks, and reads lockset and is rotated counterclockwise, and while having rotated the corresponding number of turns, can determine lockset in unlocking condition; If deploy switch is set to turn clockwise and unblanks, read lockset and be rotated counterclockwise, and while having rotated the corresponding number of turns, can determine lockset in locking state.But, processor reads the configuration status of rotation direction, do not have definite time sequencing, both can before reading lockset rotation direction, just can read in advance the configuration status of rotation direction, also can after reading rotation direction and number of revolutions, read again, can above-mentioned steps (1) or step (2) read any a moment before or afterwards can, in a word, as long as can read this state before processor does corresponding judgement.
Accompanying drawing 12 is the asynchronous signal intensity schematic diagram of lock core direction of rotation, wherein, supposes that protruding key magnitude setting is 3, and position is identical with set position in this accompanying drawing 6; H(is high in CFG configuration) unblank for being rotated counterclockwise, L(is low) unblank for turning clockwise, IN1 is for being rotated counterclockwise direction signal, and IN2 is the direction signal that turns clockwise, and IN1 and IN2 are initially low level signal.
