The key management device of the embodiment of the utility model has the following working principle:
(1) The key ring 100 is composed of a lock body 102, an induction tag 103 and a U-shaped lock tongue 101, and generally, a key can be provided with a special key ring 100; the U-shaped lock tongue 101 may be integrally formed of stainless steel, and the U-shaped lock tongue 101 may pass through a hole on the key, and once the U-shaped lock tongue 101 is closed, the U-shaped lock tongue 101 cannot be re-opened, and only the lock body 102 can be damaged, so that others are prevented from falling the key, and if the lock body 102 is damaged, the key cannot be returned to the sensing cavity 202 of the corresponding sensing lock 200 again, the safety of the key is doubly ensured, and the in-place and lost conditions of the key are monitored in real time.
(2) The induction lock 200 consists of a shell 201, a control circuit board 203, a status indicator lamp, a touch switch 205, an induction coil 206, an electromagnet 207, a photoelectric switch 209 and the like; when the key ring 100 is buckled in the sensing cavity 202 of the sensing lock 200, the lock body 102 of the key ring 100 presses the touch switch 205, the control circuit board 203 starts to work at this moment, the sensing tag 103 of the key ring 100 is detected through the sensing coil 206, whether the key ring 100 is the key ring corresponding to the sensing lock 200 is identified, if yes, the electromagnet 207 is triggered to lock, the electromagnet 207 is clamped with the locking hole 104 to lock the key ring 100 in the sensing cavity 202, at this moment, the key returns successfully, the status indicator lamp is green, if the fact that the key ring 100 does not correspond is detected, the electromagnet 207 is not locked, the status indicator lamp is red, or a warning is sent out in other modes; the locking and unlocking conditions of the electromagnet 207 can be detected by the photoelectric switch 209; the situation of returning the key by false is avoided through the identification means, and the true and false keys are identified.
The key management device of the embodiment of the utility model has the following advantages:
(1) The induction lock can monitor the in-place condition of the key ring in real time, and the key ring corresponds to the key one by one and is integrated, so that the in-place condition of the key can be monitored by the induction lock in real time, the condition of returning the key is avoided, the true and false key is identified, the receiving and returning management process of the key is perfected, and the safety of the key is ensured.
(2) The touch switch is used for detecting whether the key ring is inserted in place, when someone else removes the induction tag from the key ring independently to when directly putting into the induction cavity of induction lock with the induction tag, because the volume of induction tag is very little, hardly touch or last to push down the touch switch in the induction cavity, consequently induction coil can not start discernment, and control circuit board still detects the induction cavity as the condition that the key is not in this moment.
(3) The purpose that sets up the electro-magnet is anti-theft, for example, the intelligent key cabinet on the market can be cooperated to the inductive lock together use, can install a plurality of inductive locks in the cabinet, distribute personnel's permission for every inductive lock through key cabinet operating system, after someone opens the cabinet door through authentication module such as face identification, then only the electro-magnet of distributing his inductive lock can unlock, and the electro-magnet of other inductive locks is in the state of locking, this personnel can't take out the key ring of other inductive locks to play the function of anti-theft.
(4) The photoelectric switch is arranged for preventing theft, because the electromagnet can be pried off by some tools to unlock forcibly, but the abnormal unlocking can be detected by the control circuit board through the photoelectric switch; the control circuit board can send an abnormal signal to the key cabinet operating system, and the operating system sends a short message to an administrator and the like.
(5) When a plurality of induction locks are arranged in the key cabinet, a shielding plate is arranged at the back of the induction lock shell to shield signal interference in order to avoid mutual interference between induction coils caused by too close distance.
The above embodiments are only preferred embodiments of the present utility model, and the scope of the present utility model is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present utility model are intended to be within the scope of the present utility model as claimed.
