That is, the electronic lock resisting magnetic field or Tesla interference provided by the invention does not rely on single-point or multi-point trigger pulse type unlocking, that is, the lock body 10 is controlled to unlock after the single-point or multi-point touch chip outputs a pulse signal, but when the unlocking starting operation is detected, the control module 30 outputs an unlocking instruction to the switch module 20 first, and receives the encryption coding command returned by the switch module 20 according to the unlocking command, and collates the encryption coding command, only when the received encryption coding command is successfully collated after being detected through external transmission, only the unlocking instruction is output to the lock body 10 to control the lock body 10 to unlock, so that not only a single-point or multi-point touch chip is saved, meanwhile, the phenomenon that the single-point or multi-point trigger pulse type unlocking is easily interfered by a magnetic field to cause mistaken unlocking operation is solved, the stability of a product is effectively improved, and the safety of a user in the using process is protected.
Specifically, the electronic lock resisting magnetic field or tesla interference further includes a level maintaining module 40, the level maintaining module 40 is connected to the switch module 20 and the control module 30, specifically, the switch module 20 has at least two contacts, wherein the level maintaining module 40 connects a first contact of the switch module 20 and a first signal terminal of the control module 30, a second contact of the switch module 20 is connected to a second signal terminal of the control module 30, when the electronic lock does not enter a one-key unlocking state, the level maintaining module 40 outputs a first level to the first contact of the switch module 20 and the first signal terminal of the control module 30, the control module 30 outputs a second level to the second contact of the switch module 20 through the second signal terminal, that is, when the electronic lock does not enter the one-key unlocking state, the first contact of the switch module 20 will be maintained at the first level under the control of the level maintaining module 40, the second contact of the switch module 20 is maintained at the second level under the control of the second signal terminal of the control module 30, when the user inputs to start the unlocking operation, the first contact is short-circuited with the second contact, and at this time, the first contact of the switch module 20 outputs a trigger start signal to the first signal terminal of the control module 30, i.e., when the user is performing one-touch unlocking, the first contact and the second contact will be short-circuited, so that the level state of the first contact will be changed from the first level to the second level, the level transition trigger signal is a trigger start signal, and is synchronously outputted to the first signal terminal of the control module 30, and when the control module 30 receives the trigger start signal, then enter a key unlock state, detect the current start-up unlock operation by detecting whether the first contact and the second contact of the switch module 20 are short, the detection mode is convenient and accurate, and provide a detection basis for the subsequent reliable unlock.
In a specific implementation, the first level and the second level may be set according to specific requirements, for example, when the first level is a high level, the second level is a low level, and the trigger start signal is a falling edge signal, and when the first level is a low level, the second level is a high level, and the trigger start signal is a rising edge signal.
Preferably, when the first contact of the switch module 20 is short-circuited with the second contact and the first contact outputs a trigger start signal to the control module 30 to enable the control module to enter a one-key unlocking state, the control module 30 continuously outputs a plurality of times of unlocking instructions to the second contact of the switch module 20 and receives a plurality of times of encrypted coding instructions output by the first contact of the switch module 20 through the first signal end, that is, the unlocking instructions output by the second signal end of the control module 30, when the first contact and the second contact are short-circuited, the encrypted coding instructions are transmitted from the outside of the switch module 20 and then fed back to the first signal end of the control module 30, the encrypted coding instructions received each time are collated, when all the encrypted coding instructions are collated successfully, the unlocking instructions are output to the lock body 10 to control unlocking of the lock body 10, and the models received through the first signal end are collated continuously for a plurality of times, whether the received feedback signal is correct or not is judged, and then unlocking is controlled, so that the one-key unlocking safety is further ensured.
