Example one

As shown in fig. 1 and fig. 2, an in-place monitoring device for a key according to an embodiment of the present invention includes a key holder 10, where the key holder 10 is provided with a key insertion hole 101 for inserting the key 30, a code recognition module (not shown) for recognizing the key 30, and a self-locking component (not shown) for locking the key 30, and the self-locking component can automatically lock the key 30 when the key 30 is inserted to a set position, and of course, as another possible implementation manner of the self-locking component of this embodiment, the self-locking component can also lock the key 30 in the key insertion hole 101 after the key 30 is verified by the code of the code recognition module; the above-mentioned on-site monitoring device further comprises a detection structure, which can detect whether the key 30 is inserted to the set position. Different from the prior art, in this embodiment, when returning the key, the code recognition module is in a dormant (standby) state or a shutdown state, when the key 30 is inserted into the key jack 101 and inserted to a set position, the self-locking part can automatically lock the key 30, the set position is a locking position where the key 30 can be locked by the self-locking part, meanwhile, the key 30 can trigger the detection structure, the detection structure can wake up or start the code recognition module in the dormant state or the shutdown state after being triggered, and the code recognition module can recognize and verify the code of the key 30. In specific application, when the key 30 is not inserted into the key insertion hole 101, the self-locking part may be in a locked state, that is, the self-locking part is in a locked state in a normal state, and after the key 30 is inserted into the set position, the locking of the self-locking part and the code reading of the code identification module may be performed synchronously, or the self-locking part firstly locks the key 30 and then the code identification module reads the code.

Compared with the prior art, the start of the code identification module in the embodiment is provided with a precondition, that is, the code identification module is started only when the detection structure detects that the key 30 is inserted into the set position, so that the problem of key false lock caused by code verification of the key by the code module because the key is not inserted into the set position in the prior art is effectively solved (namely, the key is not inserted into the set position, the code identification module performs code verification, and informs a user that the key is returned, but the self-locking component does not lock the key), and the accuracy and stability of key management are improved. When the present embodiment is applied to a key management device, for example, a key management cabinet, a key management direction or other key management systems, when the key management device performs daily routing inspection, the code identification module is adopted in the prior art to directly perform in-place information routing inspection on the key, so that the power consumption is high, the conformity is large, and the time spent is long. Specifically, adopt the code identification module to carry out the prior art of patrolling and examining, the electric current needs 100mA when it patrols and examines, the time is about 100mS, and this embodiment is when patrolling and examining, can not start the code identification module and directly carry out information acquisition on site through detecting the structure, it patrols and examines the electric current and only has 5mA, the time only needs 5mS, compare in prior art, consumption and the running load when can reduce key management equipment effectively, and the time spent is shorter, efficiency is higher, can prolong the life of key management equipment to a certain extent.

Specifically, as shown in fig. 2, as a first possible implementation manner of the detection structure in this embodiment, the detection structure includes a tilting rod component and a sensing component, the tilting rod component includes a tilting rod 20, one end of the tilting rod 20 is a pressing end 201 that can be pushed by the key 30, the other end of the tilting rod 20 is a sensing end 202 that is used for triggering the sensing component, and the sensing end 202 can be close to or far from the sensing component. When the key 30 is inserted into the key insertion hole 101 and pushes the abutting end 201, the sensing end 202 of the tilting rod 20 swings in the direction opposite to the insertion direction of the key 30, when the key 30 pushes the abutting end 201 to a set position, the sensing end 202 triggers the sensing part, the state of the sensing part changes, and the code recognition module is started to read the code of the key 30 and verify whether the code is consistent with the set code. Thus, the detection of the insertion position of the key 30 is realized through the matching of the tilting rod 20 and the sensing part, i.e. it can be checked whether the key 30 is inserted in place or fully into the key cylinder 101, when the key 30 is detected to be inserted into the set position, the sensing component triggers the code identification module to perform code verification on the key 30, meanwhile, the self-locking part can lock the key 30, and after the key 30 passes the verification, the user is prompted to return and lock the key 30, so that the problem that the key is not inserted into a set position in the prior art is effectively solved, the code identification module performs code verification to cause a key false lock problem (namely, the key is not inserted into a set position, the code identification module performs code verification and informs a user that the key is returned, but the self-locking component does not lock the key), so that the accuracy and the stability of key management are improved.

Optionally, as a second possible implementation manner of the detection structure in this embodiment, the detection structure includes a sensing switch disposed in the key cylinder 101, the sensing switch may be located at the bottom of the key cylinder 101, or may be located on a side wall of the key cylinder 101, and when the key 30 is inserted into the key cylinder 101 and triggers the sensing switch, the sensing switch may start or wake up the code recognition module to perform code verification on the inserted key. Preferably, the inductive switch may employ at least one of a micro switch, a travel switch, a contact switch, or an infrared switch.

It can be understood that the key 30 described in this embodiment is inserted into the key insertion hole 101, and may be a key body inserted into the key insertion hole 101, or an identity pendant connected to the key body inserted into the key insertion hole 101, that is, the key 30 may include a key body and a pendant connected to the key body, and the like.

Specifically, as shown in fig. 2, as a first possible implementation manner of the seesaw member of this embodiment, the seesaw member further includes a support rod 21, the seesaw rod 20 is rotatably connected to the support rod 21 to form a lever structure, and the seesaw rod 20 can swing around the support rod 21 as a fulcrum.

Further, as shown in fig. 2, the top of the supporting rod 21 is provided with a limiting groove 211 for allowing the tilting rod 20 to pass through, a limiting column 212 is arranged in the limiting groove 211, the tilting rod 20 is provided with a limiting through hole 203 for allowing the limiting column 212 to extend into, the tilting rod 20 is connected to the limiting groove 211 at the top of the supporting rod 21, the limiting column 212 in the limiting groove 211 extends into the limiting through hole 203 of the tilting rod 20, the freedom of movement of the tilting rod 20 is limited, and therefore the stability of the tilting rod 20 in swinging when the tilting rod 20 abuts against the key 30 is improved. Further, the upper end edge of the limiting column 212 may be provided with a rounded corner, so that the limiting column 212 is inserted into the limiting through hole 203, and the tilting rod 20 can be ensured to swing up and down normally. Furthermore, the edge of the groove bottom of the limiting groove 211 (i.e. the surface of the limiting groove 211 abutting against the tilting rod 20) may also be provided with a rounded corner, so that the contact area between the tilting rod 20 and the groove bottom of the limiting groove 211 may be reduced, and the tilting rod 20 may swing more sensitively. Of course, the tilting rod 20 can also be directly and rotatably connected to the supporting rod 21 through the rotating shaft, and thus, similar effects to the present embodiment can also be achieved.

Specifically, as a second possible implementation manner of the seesaw member of the present embodiment, the seesaw rod 20 may also be directly rotatably connected to the side wall of the key insertion hole 101.

Specifically, as shown in fig. 2, the pressing end 201 of the tilting rod 20 has a front surface and a back surface, the front surface of the pressing end 201 faces the key 30 inserted into the key insertion hole 101, and the back surface of the pressing end 201 is connected with the spring 22, in this embodiment, the key holder 10 is connected to the mounting surface 40, one end of the spring 22 is connected to the back surface of the pressing end 201, and the other end of the spring 22 is connected to the mounting surface 40. Referring to fig. 3, when the key 30 is not inserted into the key insertion hole 101, the spring 22 can apply an upward acting force to the pressing end 201 and lift the pressing end 201, so that the pressing end 201 is at a high position and the sensing end 202 is at a low position; referring to fig. 4, when the key 30 is inserted into the key insertion hole 101, after the key 30 is inserted to the set position, the key 30 contacts the pressing end 201 and compresses the spring 22 to push the pressing end 201 to the low position, and the sensing end 202 moves to the high position to trigger the sensing part. Due to the design, the tilting rod 20 can be ensured to reset in time, the reliability of the tilting rod 20 during swinging is improved, and false detection caused by jamming during swinging of the tilting rod 20 is avoided.

In a specific application, as another possible implementation manner of this embodiment, one end of the spring 22 is connected to the back surface of the pressing end 201, and the other end of the spring 22 is connected to the bottom of the key insertion hole 101, that is, the pressing end 201 extends into the key insertion hole 101, and the spring 22 is disposed in the key insertion hole 101, and two ends of the spring 22 are respectively connected to the back surface of the pressing end 201 and the bottom of the key insertion hole 101, but do not hinder the insertion of the key 30.

Further, as shown in fig. 2, a connecting protrusion 25 is disposed on the back surface of the abutting end 201, and the connecting protrusion 25 extends into the center of the spring 22, so as to ensure that the acting force of the spring 22 is always in the vertical direction (i.e. along the axial direction of the key cylinder 101) when the spring 22 is compressed and reset, thereby ensuring the reliability of the swing of the tilting rod 20.

In a specific application, when the key 30 is not inserted into the key insertion hole 101, the tilting rod 20 may also be in a balanced position, that is, the height of the pressing end 201 is equal to the height of the sensing end 202, and when the key 30 is inserted into the set position, the pressing end 201 is pushed to the low position by the key 30, and the sensing end 202 moves to the high position and triggers the sensing component.

Specifically, as shown in fig. 1, the key insertion hole 101 may be a through hole, and a sidewall of the key insertion hole 101 is provided with a notch 102 for the tilting rod 20 to extend into the key insertion hole 101, and the notch 102 penetrates through the sidewall of the key insertion hole 101 and faces the tilting rod 20. The notch 102 facilitates the tilting of the rocker 20 when the rocker 20 is pressed or reset by the key 30. Specifically, as shown in fig. 2, as a first possible implementation manner of the sensing component of this embodiment, the sensing component includes a magnetic member 23 disposed at the sensing end 202 and a sensor 24 that can be triggered by the approach of the magnetic member 23, in this embodiment, the sensor 24 may be disposed on the mounting surface 40 of the key holder 10, and the sensing end 202 may be located directly above the sensor 24. Referring to fig. 3, when the key 30 is not inserted into the key cylinder 101, the magnetic member 23 and the sensing end 202 are close to the sensor 24; referring to fig. 4, when the key 30 is inserted into the key insertion hole 101 and pushes the pressing end 201 to a set position, the magnetic member 23 moves upward away from the sensor 24 along with the sensing end 202, the state of the sensor 24 changes, and the code recognition module can read and verify the code of the key 30.

In certain applications, the sensor 24 may also be disposed above the sensing end 202. When the key 30 is not inserted into the key cylinder 101, the sensing end 202 is far away from the sensor 24, and when the key 30 is inserted into the key cylinder 101 and pushes the pressing end 201 to a set position, the sensing end 202 swings upwards and approaches to trigger the sensor 24.

In a specific application, two sensors 24 may be provided, which correspond to the upper and lower positions of the sensing end 202, respectively, so that the sensing end 202 can be swung upward or downward to trigger the corresponding sensors.

Further, the sensor 24 in this embodiment is preferably a hall device, in a specific application, other sensors 24 may also be selected, for example, a reed pipe, and the magnetic member 23 may also be changed according to the selected sensor 24, for example, the sensor 24 is a distance sensor, and the sensing end 202 may not be provided with the magnetic member 23.

Specifically, as a second possible implementation manner of the sensing part of this embodiment, the sensing part includes a light emitting element and a light receiving element oppositely disposed at two sides of the sensing end 202, and the sensing end 202 can block a light path between the light emitting element and the light receiving element. Thus, when the pressing end 201 is pushed to the set position by the key 30, the sensing end 202 swings upwards, so that the state of the light receiving element is changed, and the code identification module is triggered to perform code verification.

Specifically, the auto-lock part includes telescopic pin and the driving piece that is used for driving telescopic pin, and telescopic pin can set up in key socket 101's lateral wall, and key 30 can be provided with and be used for supplying telescopic pin male locking groove, and the driving piece can select for use electromagnetic driving piece, also can select for use other driving pieces. As a first possible implementation manner of the self-locking part of this embodiment, the portion of the key 30 inserted into the key insertion hole 101 may be provided with a guiding structure cooperating with the telescopic pin, and the guiding structure may be an inclined surface or a curved surface. When the key 30 is inserted into the key insertion hole 101, the guide structure abuts against the retractable pin and pushes the retractable pin to retract the retractable pin until the locking groove moves to be aligned with the retractable pin, and the retractable pin is inserted into the locking groove to lock the key 30 to the key insertion hole 101. Of course, a curved surface or an inclined surface may be provided at the end of the retractable pin contacting the key 30, and a self-locking effect may also be achieved.

In a specific application, when the key 30 is not inserted into the key insertion hole 101, the self-locking member may be in a locked state, i.e., the retractable pin extends into the key insertion hole 101 in a normal state.

Optionally, as a second possible implementation manner of the self-locking part of this embodiment, when the key 30 is inserted into the set position of the key insertion hole 101, the sensing end 202 triggers the sensing part, so that the code identification module performs code reading and verification on the key 30, and the verification can drive the retractable pin to be inserted into the locking groove through the rear driving piece, so as to lock the key 30 in the key insertion hole 101. In a specific application, when the key is not inserted into the key insertion hole 101, the self-locking component may be in an unlocked state, that is, the retractable pin does not extend into the key insertion hole 101 in a normal state.

Specifically, the code identification module may adopt an RFID code reading module, that is, the code identification module may read the code of the RFID code chip of the key 30, and of course, in practical applications, other induction identification modules may also be adopted. It can be understood that the code identification module described in this embodiment includes code reading and code verification, and the code verification can compare the read key code with a preset key code, thereby implementing verification of the key identity.

Specifically, the key holder 10 is provided with a prompting means for displaying the presence state of the key 30, the prompting means including a state prompting lamp or/and a speaker. In this embodiment, the prompting component adopts a status prompting lamp, and the status relationship between the status prompting lamp and each component is shown in the following table:

In the table, the low level indicates that the key 30 is in place (sensing end 202 is away from the sensor 24), and the high level indicates that the key 30 is not in place or is not inserted to a set position (sensing end 202 is close to the sensor 24).

Before taking, as shown in fig. 4, the key 30 is located in the key jack 101 and at a set position, the abutting end 201 is at a low position, the sensing end 202 is at a high position (i.e. the sensing end 202 is far away from the sensor 24), the sensor 24 is at a low level state, the code identification module reads and verifies the code of the key 30, the key 30 is unlocked by the self-locking component through verification, at this time, the status indicator light flashes red, the key 30 is in a standby state, and if the code verification fails, the status indicator light flashes alternately red and green.

After the key is used, as shown in fig. 3, the key 30 is pulled out, the pressing end 201 is changed from the low position to the high position under the action of the spring 22, the sensing end 202 is changed from the high position to the low position (the sensing end 202 is close to the sensor 24), the sensor 24 is changed from the low level to the high level, and at this time, the status indicator light is red.

Before returning, as shown in fig. 3, the pressing end 201 is at a high position, the sensing end 202 is at a low position (the sensing end 202 is close to the sensor 24), the sensor 24 is at a high level state, at this time, the code identification module and the self-locking component do not act, and the state indicator light flashes in a green light state to wait for the key 30 to be inserted into the key jack 101.

After returning, as shown in fig. 4, the key 30 is inserted into the key insertion hole 101, the key 30 pushes the pressing end 201 of the tilting rod 20 to a set position, the pressing end 201 changes from a high position to a low position, the sensing end 202 changes from a low position to a high position (the sensing end 202 is far away from the sensor 24), the sensor 24 changes from a high level to a low level, the key is inserted into the set position, the self-locking component unlocks the key 30, the detection structure triggers the code identification module to identify and verify the code of the key 30, if the code verification passes, the status indicator light is green light, if the code verification fails, the status indicator light flashes alternately in red and green, and the self-locking component unlocks the key 30.

Example two

The embodiment of the invention provides an in-place monitoring method of a key, which adopts the in-place monitoring device of the key and comprises a key taking step or/and a key returning step,

the step of taking a key includes:

the key 30 is kept inserted into the key cylinder 101 at a predetermined position, and the code recognition module performs code verification on the key 30.

In a specific application, when the key 30 is taken out, the key 30 is inserted into the key insertion hole 101, the self-locking part is in a state of locking the key 30, the key 30 is kept abutting against the abutting end 201 of the tilting rod 20, the sensing end 202 of the tilting rod 20 is far away from the sensing part, and the code identification module reads the code of the key 30 and compares the code with a preset code. The sensing end 202 is far away from the sensing part, which indicates that the key 30 is located at the set position of the key jack 101, and at this time, the code identification module verifies the code reading of the key 30; if the sensing end 202 is close to the sensing part, it indicates that the key is not in the key insertion hole 101 or the key 30 is not inserted in place, and at this time, the code identification module does not read and verify the code, so that the workload of the code identification module can be reduced, and the service life of the on-site monitoring device can be prolonged to a certain extent.

If the code read by the code recognition module is consistent with the preset code, the self-locking component releases the locking of the key 30, and the key 30 can be pulled out of the key jack 101.

In a specific application, after the key 30 is pulled out of the key insertion hole 101, the pressing end 201 of the tilting rod 20 moves upwards under the action of the spring 22, and the sensing end 202 of the tilting rod 20 is close to the sensing part;

further, if the code read by the code recognition module is consistent with the preset code, the prompting component prompts the user that the key 30 waits to be pulled out; if the code read by the code identification module is inconsistent with the preset code, the self-locking part unlocks the key 30, and meanwhile, the prompting part prompts a user that the key 30 is not matched with the key seat 10;

further, when the key 30 is removed, the indicating member indicates that the key has been removed.

In a specific application, the prompting component may be a status prompting lamp or a speaker, or both of them may be used together. Specifically, when the code read by the code recognition module is consistent with the preset code, the status indicator light may display red light flashing to indicate to the user that the key 30 is to be pulled out; when the code read by the code identification module is inconsistent with the preset code, the state prompt lamp can display that the traffic light flashes alternately to prompt a user that the key 30 is not matched with the key seat; after the key 30 is pulled out of the key cylinder 101, the status indicator light may turn to red light.

The key returning step comprises the following steps:

when the key 30 is inserted into the key insertion hole 101, the self-locking part can automatically lock the key 30 and simultaneously trigger the code identification module to perform code verification on the key 30 when the key 30 is inserted to a set position.

In specific application, when the key 30 is inserted into the key insertion hole 101, the key 30 pushes the abutting end 201 of the tilting rod 20 and enables the sensing end 202 of the tilting rod 20 to be far away from the sensing part, when the key 30 is inserted into the key insertion hole 101 at a set position, the self-locking part can automatically lock the key 30, meanwhile, the sensing end 202 is far away from and triggers the sensing part, the code recognition module is started to read the code of the key 30, and the code is compared with the preset code. The key 30 is used for pushing the abutting end 201 of the tilting rod 20, so that the sensing end 202 of the tilting rod 20 is far away from and triggers the sensing part, and at the moment, the key 30 is indicated to be inserted into the set position of the key jack 101, and the code identification module can start the verification of code reading; on the contrary, if the sensing end 202 does not trigger the sensing part, it indicates that the key 30 is not inserted into the key insertion hole 101 or inserted to the set position, and the code recognition module is not started, so that the workload of the code recognition module can be reduced. Therefore, the problem that in the prior art, the key is not inserted in place, the self-locking part does not lock the key 30 yet, and the code identification module is started for verification to cause key false locking is solved, and the operation efficiency of the on-site monitoring device is improved.

If the code read by the code recognition module is consistent with the preset code, the prompt component prompts the user that the key 30 is returned.

Further, if the code read by the code recognition module is not consistent with the preset code, the self-locking part releases the locking of the key, and simultaneously the prompting part prompts the user that the key 30 is not matched with the key seat 10.

In the present embodiment, after the key 30 is inserted to the set position, the locking of the self-locking part and the code reading of the code recognition module may be performed simultaneously, or the self-locking part is locked first, and the code recognition module reads the code again, and in this embodiment, when the key 30 is not inserted into the key insertion hole 101, the self-locking part may be in a locked state, for example, before the key 30 is inserted, the retractable pin of the self-locking part extends into the key insertion hole 101, after the key 30 is inserted, the key 30 pushes the retractable pin to retract until the key 30 is inserted to the set position, and the retractable pin extends into the key insertion hole 101 and locks the key 30.

Alternatively, as another possible implementation manner of the step of returning the key in this embodiment, the step of returning the key includes:

when the key 30 is inserted into the key jack 101 at a set position, the self-locking part is in a locking release state, the key 30 is inserted into the key jack 101, the key 30 pushes the abutting end 201 of the tilting rod 20 and enables the sensing end 202 of the tilting rod 20 to be far away from the sensing part, and when the key 30 is inserted into the key jack 101 at the set position, the sensing end 202 is far away from and triggers the sensing part, the code identification module is started to read the code of the key 30, and the code is compared with the preset code; if the code read by the code recognition module is consistent with the preset code, the self-locking part locks the key 30. Compared with the first possible implementation mode, the self-locking part is started to lock the key 30 after the key code verification is passed, so that when the self-locking part is started, the key 30 is certainly inserted into the set position of the key jack 101, the problem that the key is not inserted in place and the self-locking part does not lock the key 30 yet in the prior art, and the code identification module is started to verify the key to cause false locking can be solved, and the operation efficiency of the in-place monitoring device is improved.

Further, if the code read by the code recognition module is consistent with the preset code, the prompt component prompts the user that the key 30 is returned; if the code read by the code recognition module is not consistent with the preset code, the prompting component prompts the user that the key 30 is not matched with the key seat 10.

In a specific application, if the code read by the code recognition module is consistent with the preset code, the state indicator light can display a green light to light, and the user is prompted that the key 30 is returned; if the read code is not consistent with the preset code, the status indicator light can display that the traffic light flashes alternately to indicate that the key 30 is not matched with the key seat 10.

In particular, the in-place monitoring method also comprises a self-checking step,

the self-checking step comprises:

the code identification module starts code verification, reads a key code in the key jack 101, and the detection structure detects whether the key 30 in the key jack 101 is in place;

if the code identification module reads the key code and the detection structure does not detect the in-place information of the key 30, or the code identification module does not read the key code and the detection structure detects the in-place information of the key 30, the prompt component prompts fault information to prompt a manager that at least one of the code identification module and the detection structure has a fault and the manager needs to overhaul in time.

The embodiment of the invention also provides another key in-place monitoring method, which adopts the key management cabinet and comprises a key taking step or/and a key returning step,

the step of taking a key includes:

the authorization verification module receives a key access request;

the control module controls a detection structure of the in-place monitoring device to detect whether a key 30 is in place in the key jack 101, and if the detection structure detects the key 30, the code identification module is triggered to carry out code verification on the key 30;

if the code identification module passes the code verification of the key 30, the self-locking component releases the locking of the key 30.

Further, if the detection structure detects that the key 30 is not in the key cylinder 101, the code identification module is not triggered and the prompting component sends a signal that the key 30 is not in the position.

Further, if the code identification module fails to verify the code of the key 30, the self-locking unit releases the lock of the key and simultaneously prompts the unit to signal that the key 30 is not matched with the key holder 10.

Further, after the self-locking means releases the lock of the key 30, if the key 30 stays in the key cylinder 101 for a time period longer than a set time period, the self-locking means re-locks the key 30.

The key returning step comprises the following steps:

the authorization verification module receives a return key request;

the key 30 is inserted into the key insertion hole 101 of the key holder 10, and if the key 30 is inserted to a set position, the self-locking part locks the key and simultaneously triggers the code identification module to perform code verification on the key 30.

Further, if the code identification module does not verify the code of the key 30, the prompting component sends a signal that the key 30 is not matched with the key seat 10, and meanwhile, the self-locking component releases the locking of the key 30; if the code identification module verifies the code of the key 30, the prompting component prompts that the key is returned.

the self-checking step comprises:

On one hand, before the key is taken, whether the key 30 in the key jack 101 is in place is detected through a detection structure, and then the key 30 is subjected to coding verification through a coding identification module, so that the coding verification of the vacant key jack 101 by a coding verification module is avoided, the running load of an in-place monitoring device or a key management cabinet is reduced, and the service life of equipment is prolonged to a certain extent; on the other hand, when the key is returned, the position of the key 30 inserted into the key insertion hole 101 is detected through the detection structure, and after the key 30 is inserted into the set position, the key 30 is coded, verified and locked, so that the problem of key false locking caused by the fact that the key is not inserted into the set position, the self-locking part does not lock the key and the code identification module carries out code verification in the prior art is solved, and the accuracy and the reliability of the management key of the key management cabinet are improved; moreover, automatic inspection of the equipment can be realized through the self-inspection step, the fault condition of the equipment can be found in time, and the operation efficiency is improved.
