During smart lock closing detecting apparatus work provided by the invention, card fastens built-in two magnet, the magnetic of this two magnet
Flux is more than the detection threshold value of the Hall sensor used, i.e., when magnet is above Hall sensor, can trigger Hall biography
The interruption of sensor, then notification controller 21, the controller 21 are MCU；
Hall sensor is located near snib 1, it is not necessary to and snib 1 contacts, when the internal magnet of snib 1 is in Hall sensor
During top, it is possible to which triggering is interrupted, notification controller 21, then knows above Hall sensor there is a magnet；
When the first Hall sensor 9 detection magnetic flux, which exceedes threshold triggers, to interrupt, and the detection of the second Hall sensor 8 does not have
Threshold triggers interruption is had more than, as shown in figure 3, now snib 1 is on the outside of bayonet socket 2, so now smart lock is in unlocking condition；
Threshold value is not above when the first Hall sensor 9 detects magnetic flux, and the detection of the second Hall sensor 8 exceedes threshold value
Triggering interrupt, as shown in figure 5, now snib 1 at bayonet socket 2, so now smart lock be in shut state；
As shown in figure 4, working as the first Hall sensor 9 detects that magnetic flux interrupts more than threshold triggers, and the second Hall passes
Sensor 8 also detects to be interrupted more than threshold triggers, and now snib 1 is in traveling process, is not pushed up at bayonet socket 2, now intelligence
Lock is in unlocking condition.
When the first Hall sensor 9 and the second Hall sensor 8, all detection magnetic flux does not exceed threshold value, now belongs to different
Normal state, possible Hall sensor is abnormal, or installation site is incorrect, and other exceptions etc..
In summary, hall principle is applied in smart lock closing detecting apparatus provided by the invention, is set on snib 1
There is magnet, Hall sensor is provided with housing 4, it is not necessary to which contact then realizes detection so that intelligent lock-switch detection dress
Waterproof and dustproof design can preferably be done by putting, and have the advantages that simple in construction, cost is low and service life is long.
