Description

Technical Field

[0001] The present invention belongs to the field of key management equipment, and in particular relates to a key on-site monitoring device, an on-site monitoring method and a key management cabinet. Background Art

[0002] The key management device is a device used to control keys. It can record the specific time, key type and applicable reason for taking or returning keys. It can effectively standardize the key management level, avoid misuse of keys and cause erroneous operations, and also reduce the workload of manual management.

[0003] The key management device in the prior art generally inserts the key into the key socket on the key holder, and the self-locking component in the key socket locks the key in the key holder, and the key is coded and verified by the coding recognition module of the key holder. After the coding verification is passed, the user is prompted with the key return information. However, the identification module in the prior art generally uses an RFID chip (Radio Frequency Identification) to realize the coding recognition of the key. The stability and accuracy of RFID code reading are easily affected by environmental factors such as temperature, electromagnetic interference, and sensing distance, resulting in the RFID code reading module being able to only detect whether the key is in the key socket, but unable to accurately determine whether the key is inserted in place, causing the self-locking component to be unable to lock the key in the key socket, resulting in the key virtual lock phenomenon. At the same time, when the key management device is regularly or irregularly inspected, the RFID code reading module is also prone to misjudging the key in place, causing inconvenience to the management and use of the key. And with the increase in the number of inspections, the operating load and maintenance frequency of the key management device will also increase accordingly, which to a certain extent affects the service life of the key management device.

[0047] The various specific technical features and embodiments described in the specific implementation methods can be combined in any suitable manner unless there is any contradiction. For example, different implementation methods can be formed by combining different specific technical features / embodiments. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features / embodiments in the present invention will not be described separately.

[0048] Embodiment 1

[0049] like Figure 1 and Figure 2As shown, a key presence monitoring device provided by an embodiment of the present invention includes a key seat 10, and the key seat 10 is provided with a key socket 101 for inserting a key 30, a code recognition module (not shown in the figure) for identifying the key 30, and a self-locking component (not shown in the figure) for locking the key 30. The self-locking component can automatically lock the key 30 when the key 30 is inserted into the set position. Of course, as another possible implementation of the self-locking component of this embodiment, the self-locking component can also lock the key 30 in the key socket 101 after the key 30 passes the code verification of the code recognition module; the above-mentioned presence monitoring device also includes a detection structure, which can detect whether the key 30 is inserted into the set position. Different from the prior art, in this embodiment, when the key is returned, the coding identification module is in a dormant (standby) or shutdown state. When the key 30 is inserted into the key hole 101 and inserted to the set position, the self-locking component will automatically lock the key 30. The set position is the locking position where the key 30 can be locked by the self-locking component. At the same time, the key 30 will trigger the detection structure. After the detection structure is triggered, it will wake up or start the coding identification module in the dormant or shutdown state. The coding identification module will then identify and verify the code of the key 30. In a specific application, when the key 30 has not yet been inserted into the key hole 101, the self-locking component can be in a locked state, that is, the self-locking component is in a locked state under normal conditions. When the key 30 is inserted into the set position, the locking of the self-locking component and the reading of the coding identification module can be performed simultaneously. Of course, the self-locking component can first lock the key 30, and then the coding identification module can read the code.

[0050] Compared with the prior art, the activation of the coding recognition module in this embodiment is provided with a precondition, that is, the detection structure needs to detect that the key 30 is inserted into the set position before the coding recognition module is activated. This effectively solves the problem of key virtual lock in the prior art, which is caused by the coding module having performed coding verification on the key before the key is inserted into the set position (that is, the key has not been inserted into the set position, the coding recognition module has performed coding verification, and notified the user that the key has been returned, but the self-locking component has not locked the key), and improves the accuracy and stability of key management. In addition, when this embodiment is applied to key management equipment, such as a key management cabinet, a key management cabinet or other key management systems, when the key management equipment performs daily inspections, the prior art uses a coding recognition module to directly perform in-place information inspections on the key, which has high power consumption, large compliance and takes a long time. However, this embodiment can collect in-place information of all in-place monitoring devices through the detection structure, and does not need to use a coding recognition module to collect in-place information. Specifically, the existing technology that uses a coding recognition module for inspection requires a current of 100mA and a time of about 100mS during the inspection. However, during the inspection, the coding recognition module may not be started and in-situ information can be directly collected through the detection structure. The inspection current is only 5mA and the time is only 5mS. Compared with the existing technology, it can effectively reduce the power consumption and operating load of the key management device, and the time spent is shorter and the efficiency is higher, which can extend the service life of the key management device to a certain extent.

[0051] Specifically, Figure 2As shown, as the first possible implementation 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 for triggering the sensing component. The sensing end 202 can be close to or away from the sensing component. When the key 30 is inserted into the key hole 101 and pushes the pressing end 201, the sensing end 202 of the tilting rod 20 will swing in the direction opposite to the insertion direction of the key 30. When the key 30 pushes the pressing end 201 to the set position, the sensing end 202 will trigger the sensing component, the state of the sensing component will change, and the code recognition module will be activated to read the code of the key 30 and verify whether the code is consistent with the set code. In this way, the insertion position of the key 30 can be detected by cooperating with the tilting rod 20 and the sensing component, that is, whether the key 30 is inserted in place or fully inserted into the key socket 101 can be detected. When it is detected that the key 30 is inserted into the set position, the sensing component will trigger the coding recognition module to perform coding verification on the key 30. At the same time, the self-locking component will lock the key 30. After the verification is passed, the user is prompted that the key 30 has been returned and locked. This effectively solves the problem of key virtual lock in the prior art caused by the key not being inserted into the set position, but the coding recognition module has performed coding verification (that is, the key has not been inserted into the set position, the coding recognition module has performed coding verification, and notified the user that the key has been returned, but the self-locking component has not yet locked the key), thereby improving the accuracy and stability of key management.

[0052] Optionally, as a second possible implementation of the detection structure in this embodiment, the detection structure includes an induction switch disposed in the key hole 101. The induction switch can be located at the bottom of the key hole 101 or at the side wall of the key hole 101. When the key 30 is inserted into the key hole 101 and triggers the induction switch, the induction switch can start or wake up the code recognition module to perform code verification on the inserted key. Preferably, the induction switch can be at least one of a micro switch, a travel switch, a contact switch or an infrared switch.

[0053] It can be understood that the key 30 described in this embodiment is inserted into the key hole 101, and the key body can be inserted into the key hole 101, or the identity pendant connected to the key body can be inserted into the key hole 101, that is, the key 30 can include the key body and the pendant connected to the key body, etc.

[0054] Specifically, Figure 2 As shown, as a first possible implementation of the tilt lever component of this embodiment, the tilt lever component also includes a support rod 21, and the tilt lever 20 is rotatably connected to the support rod 21 to form a lever structure. The tilt lever 20 can swing with the support rod 21 as a fulcrum.

[0055] Furthermore, if Figure 2 As shown, the top of the support rod 21 is provided with a limiting groove 211 for the tilting rod 20 to pass through, the limiting groove 211 is provided with a limiting post 212, and the tilting rod 20 is provided with a limiting through hole 203 for the limiting post 212 to extend into, the tilting rod 20 is connected to the limiting groove 211 at the top of the support rod 21, and the limiting post 212 in the limiting groove 211 extends into the limiting through hole 203 of the tilting rod 20, which limits the freedom of movement of the tilting rod 20, thereby improving the stability of the tilting rod 20 swinging when the tilting rod 20 and the key 30 are pressed against each other. Further, the upper edge of the limiting post 212 can be provided with a rounded corner to facilitate the limiting post 212 to be inserted into the limiting through hole 203, and to ensure that the tilting rod 20 can swing up and down normally. Furthermore, the edge of the bottom of the limiting groove 211 (i.e., the surface where the limiting groove 211 and the tilting rod 20 abut against each other) can also be provided with a rounded corner, so that the contact area between the tilting rod 20 and the bottom of the limiting groove 211 can be reduced, and the swing of the tilting rod 20 can be made more sensitive. Of course, the tilting rod 20 can also be directly connected to the support rod 21 by a rotating shaft, which can also achieve an effect similar to that of the present embodiment.

[0056] Specifically, as a second possible implementation of the tilting lever component of this embodiment, the tilting lever 20 can also be directly rotatably connected to the side wall of the key hole 101 .

[0057] Specifically, Figure 2 As shown, the pressing end 201 of the tilting rod 20 has a front side and a back side. The front side of the pressing end 201 faces the key 30 inserted into the key insertion hole 101, and the back side of the pressing end 201 is connected to a spring 22. In this embodiment, the key base 10 is connected to the mounting surface 40, one end of the spring 22 is connected to the back side of the pressing end 201, and the other end of the spring 22 is connected to the mounting surface 40. Figure 3 When the key 30 is not inserted into the key hole 101, the spring 22 can exert an upward force on the pressing end 201 and lift the pressing end 201 so that the pressing end 201 is in a high position and the sensing end 202 is in a low position; see Figure 4 When the key 30 is inserted into the key hole 101 and 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 a low position, and the sensing end 202 moves to a high position and triggers the sensing component. This design can ensure that the tilting rod 20 can be reset in time, improve the reliability of the tilting rod 20 when it swings, and avoid false detection caused by the tilting rod 20 getting stuck when it swings.

[0058] In a specific application, as another possible implementation of this embodiment, one end of the spring 22 is connected to the back side of the pressing end 201, and the other end of the spring 22 is connected to the bottom of the key hole 101, that is, the pressing end 201 extends into the key hole 101, and the spring 22 is arranged in the key hole 101, and the two ends of the spring 22 are respectively connected to the back side of the pressing end 201 and the bottom of the key hole 101, but do not hinder the insertion of the key 30.

[0059] Furthermore, if Figure 2 As shown, a connecting protrusion 25 is provided on the back of the pressing end 201, and the connecting protrusion 25 extends into the center of the spring 22 to ensure that when the spring 22 is compressed and reset, the force of the spring 22 is always in the vertical direction (i.e., along the axis direction of the key hole 101), thereby ensuring the reliability of the swing of the cocking lever 20.

[0060] In a specific application, when the key 30 is not inserted into the key hole 101, the tilting rod 20 may also be in a balanced position, that is, the height of the pressing end 201 is level with the height of the sensing end 202. When the key 30 is inserted to the set position, the pressing end 201 is pushed to a low position by the key 30, and the sensing end 202 moves to a high position and triggers the sensing component.

[0061] Specifically, Figure 1 As shown, the key hole 101 can be a through hole, and the side wall of the key hole 101 is provided with a notch 102 for the tilting rod 20 to extend into the key hole 101. The notch 102 passes through the side wall of the key hole 101 and faces the tilting rod 20. When the tilting rod 20 is pressed or reset by the key 30, the notch 102 facilitates the up and down swing of the tilting rod 20. Specifically, as Figure 2 As shown in FIG. 1 , as a first possible implementation 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 proximity of the magnetic member 23. In this embodiment, the sensor 24 can be disposed on the mounting surface 40 of the key holder 10, and the sensing end 202 can be located directly above the sensor 24. Figure 3 When the key 30 is not inserted into the key slot 101, the magnetic member 23 and the sensing end 202 are close to the sensor 24; see Figure 4 When the key 30 is inserted into the key hole 101 and the pressing end 201 is pushed to the 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.

[0062] In a specific application, the sensor 24 can also be arranged above the sensing end 202. When the key 30 is not inserted into the key slot 101, the sensing end 202 is away from the sensor 24. When the key 30 is inserted into the key slot 101 and pushes the pressing end 201 to a set position, the sensing end 202 swings upward and approaches to trigger the sensor 24.

[0063] In a specific application, two sensors 24 may be provided, corresponding to the upper and lower positions of the sensing end 202 respectively, so that the corresponding sensor can be triggered when the sensing end 202 swings upward or downward.

[0064] Furthermore, the sensor 24 in this embodiment is preferably a Hall device. In specific applications, other sensors 24, such as a reed switch, etc., may also be selected, and the magnetic component 23 may also be changed according to the selected sensor 24. For example, if the sensor 24 is a distance sensor, the magnetic component 23 may not be set at the sensing end 202.

[0065] Specifically, as a second possible implementation of the sensing component of this embodiment, the sensing component includes a light emitting element and a light receiving element relatively arranged on both sides of the sensing end 202, and the sensing end 202 can block the light path between the light emitting element and the light receiving element. In this way, when the pressing end 201 is pushed to the set position by the key 30, the sensing end 202 will swing upward, causing the state of the light receiving element to change, thereby triggering the code recognition module to perform code verification.

[0066] Specifically, the self-locking component includes a telescopic pin and a driving member for driving the telescopic pin. The telescopic pin can be arranged on the side wall of the key hole 101. The key 30 can be provided with a locking groove for inserting the telescopic pin. The driving member can be an electromagnetic driving member or other driving members. As a first possible implementation method of the self-locking component of this embodiment, a guide structure that cooperates with the telescopic pin can be provided at the position where the key 30 is inserted into the key hole 101. The guide structure can be an inclined surface or a curved surface. When the key 30 is inserted into the key hole 101, the guide structure abuts against the telescopic pin and pushes the telescopic pin to retract the telescopic pin until the locking groove moves to align with the telescopic pin. The telescopic pin is inserted into the locking groove to lock the key 30 in the key hole 101. Of course, a curved surface or an inclined surface can also be provided at the end of the telescopic pin that contacts the key 30, and a self-locking effect can also be achieved.

[0067] In a specific application, in this embodiment, when the key 30 has not yet been inserted into the key socket 101 , the self-locking component can be in a locked state, that is, the telescopic pin is normally inserted into the key socket 101 .

[0068] Optionally, as a second possible implementation of the self-locking component of this embodiment, when the key 30 is inserted into the set position of the key hole 101, the sensing end 202 triggers the sensing component, so that the code recognition module reads and verifies the code of the key 30. After the verification, the driving member can drive the telescopic pin to insert into the locking groove, and lock the key 30 in the key hole 101. In specific applications, in this embodiment, when the key has not been inserted into the key hole 101, the self-locking component can be in an unlocked state, that is, the telescopic pin has not been inserted into the key hole 101 under normal conditions.

[0069] Specifically, the code recognition module can use RFID code reading, that is, the code recognition module can read the code of the RFID code chip of the key 30. Of course, in practical applications, other inductive recognition modules can also be used. It can be understood that the code recognition module described in this embodiment includes code reading and code verification. The code verification can compare the read key code with the preset key code to verify the key identity.

[0070] Specifically, the key holder 10 is provided with a prompt component for displaying the key 30 in position, and the prompt component includes a status prompt light and / or a speaker. In this embodiment, the prompt component adopts a status prompt light, and the relationship between the status prompt light and the status of each component is shown in the following table:

[0071] Sensor signal Coding Validation Self-locking parts Status indicator light Key status Before use Low level pass Unlock Red light flashing To be pulled out After use High level No action No action Red light on Unplugged Before return High level No action No action Green light flashing To be inserted After return Low level pass locking Green light Inserted

[0072] In the table, a low level means that the key 30 is in place (the sensing end 202 is far away from the sensor 24 ), and a high level means that the key 30 is not in place or has not been inserted to the set position (the sensing end 202 is close to the sensor 24 ).

[0073] Before use, Figure 4 As shown, the key 30 is located in the key socket 101 and at the set position, the pressing end 201 is in a low position, the sensing end 202 is in a high position (i.e., the sensing end 202 is away from the sensor 24), the sensor 24 is in a low level state, and the coding recognition module reads and verifies the coding of the key 30. The verification releases the lock of the key 30 through the self-locking component. At this time, the status indicator light flashes red, and the key 30 is in a waiting state. If the coding verification fails, the status indicator light flashes red and green alternately.

[0074] After use, Figure 3 As shown, when the key 30 is pulled out, the pressing end 201 changes from a low position to a high position under the action of the spring 22, and the sensing end 202 changes from a high position to a low position (the sensing end 202 is close to the sensor 24), and the sensor 24 changes from a low level to a high level. At this time, the status indicator light is red.

[0075] Before returning, if Figure 3As shown, the pressing end 201 is in a high position, the sensing end 202 is in a low position (the sensing end 202 is close to the sensor 24), and the sensor 24 is in a high level state. At this time, the coding recognition module and the self-locking component are not in operation, and the status indicator light flashes green, waiting for the key 30 to be inserted into the key socket 101.

[0076] After returning, if Figure 4 As shown, the key 30 is inserted into the key hole 101, and the key 30 pushes the pressing end 201 of the tilting rod 20 to the set position. The pressing end 201 changes from a high position to a low position, and the sensing end 202 changes from a low position to a high position (the sensing end 202 is away from the sensor 24), and the sensor 24 changes from a high level to a low level. The key is inserted to the set position, the self-locking component unlocks the key 30, and the detection structure triggers the coding recognition module to identify and verify the code of the key 30. If the coding verification passes, the status indicator light is green, and if the coding verification fails, the status indicator light flashes red and green alternately, and the self-locking component unlocks the key 30.

[0077] In specific applications, the status indicator light may be replaced by a speaker, or the status indicator light and the speaker may be used in combination.

[0078] The embodiment of the present invention also provides a key management cabinet, including a cabinet body and an authorization verification module for verifying the authorized identity. The key management cabinet also includes the above-mentioned key in-place monitoring device and a control module connected to the in-place monitoring device, and the in-place monitoring device is arranged in the cabinet body. Before taking or returning the key, you can first apply for authorization to take or return the key. After obtaining the corresponding authorization, you must first verify the user's identity and authorization status through the authorization verification module before you can open the cabinet body. If the authorization verification fails, an error message is prompted and the user is prohibited from opening the cabinet body. In specific applications, the number of in-place monitoring devices can be set in the key management cabinet according to actual needs. The in-place monitoring device can be set to one, two or more, and the authorization verification module can be at least one of a fingerprint recognition module, a face recognition module or a verification code module.

[0079] In a specific application, during the process of returning or taking keys, if an operation error occurs, causing the status indicator light to flash alternately like the red and green lights mentioned above, the key management cabinet can emit an audible and visual alarm to remind the user that an operation error has occurred. After closing the cabinet body, the unlocked key 30 will be relocked to ensure the safety of the unlocked key until the wrongly placed key is unlocked the next time it is applied for. Of course, in other embodiments, if an operation error occurs, the key management cabinet can also refuse the user's operation to close the cabinet body, that is, the cabinet body cannot be closed at this time, which can standardize the user's operation and avoid human errors. Furthermore, if the unlocked key 30 has not been pulled out during the process of taking keys, it can also be set that the cabinet body cannot be closed.

[0080] Specifically, the key management cabinet may also include an event recording module, which can record various operations of the user using the key management cabinet. The recorded matters include but are not limited to taking keys, returning keys, identity and authorization verification, inspection records, self-inspection records, and various operational errors (such as inserting the wrong key, etc.). In this way, the administrator can check the key management cabinet through the event recording module to obtain the usage of the key management cabinet, which is conducive to the management of the key management cabinet and standardizing the use of keys and the operation of the key management cabinet.

[0081] In specific applications, the key management cabinet can be provided with an interface that can be connected to the anti-error system. The anti-error system can control the key management cabinet in real time, and the information recorded by the event recording module can be synchronized to the anti-error system. Multiple key management cabinets can be connected to the same anti-error system for systematic supervision.

[0082] The embodiment of the present invention provides a key presence monitoring device and a key management cabinet. When the key 30 is inserted into the key socket 101 and presses the pressing end 201 of the tilting rod 20 to the set position, the sensing end 202 of the tilting rod 20 triggers the sensing component. Then the coding recognition module performs coding recognition on the inserted key 30 and verifies the coding of the key 30. At the same time, the self-locking component locks the key 30 in the key socket 101. After the coding verification, the prompt component prompts the user that the key 30 has been returned, thereby solving the problem of false lock caused by the key 30 not being inserted into place in the prior art. When the key management device performs daily inspection, only the presence monitoring device that triggers the sensing component can be coded detected, that is, there is no need to perform coding detection on the vacant presence monitoring device. This can effectively reduce the power consumption and operating load of the key management device during inspection, and the time spent is shorter and the efficiency is higher. The service life of the key management device can be extended to a certain extent, and it has the characteristics of high accuracy and good stability.

[0083] Embodiment 2

[0084] The embodiment of the present invention provides a method for monitoring the presence of a key, using the above-mentioned device for monitoring the presence of a key. The method comprises a key taking step and / or a key returning step.

[0085] The steps to access the key include:

[0086] The key 30 remains inserted into the key insertion hole 101 at a set position, and the code recognition module performs code verification on the key 30 .

[0087] In a specific application, when the key 30 is used, the key 30 is inserted into the key slot 101, and the self-locking component is in a state of locking the key 30. The key 30 is kept against the pressing end 201 of the tilting rod 20 and the sensing end 202 of the tilting rod 20 is kept away from the sensing component. The coding recognition module reads the code of the key 30 and compares the code with the preset code. If the sensing end 202 is away from the sensing component, it indicates that the key 30 is already at the set position of the key slot 101. At this time, the coding recognition module verifies the reading of the code of the key 30; if the sensing end 202 is close to the sensing component, it indicates that the key is not in the key slot 101 or the key 30 is not inserted in place. At this time, the coding recognition module does not read and verify the code, which can reduce the workload of the coding recognition module and improve the service life of the in-situ monitoring device to a certain extent.

[0088] If the code read by the code recognition module is consistent with the preset code, the self-locking component releases the lock on the key 30 , and the key 30 can be pulled out from the key insertion hole 101 .

[0089] In a specific application, when the key 30 is pulled out from the key insertion hole 101, the pressing end 201 of the tilting rod 20 moves upward under the action of the spring 22, and the sensing end 202 of the tilting rod 20 approaches the sensing component;

[0090] Furthermore, 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 waiting to be pulled out; if the code read by the code recognition module is inconsistent with the preset code, the self-locking component unlocks the key 30, and at the same time the prompt component prompts the user that the key 30 does not match the key seat 10;

[0091] Furthermore, after the key 30 is pulled out, the prompt component prompts that the key has been pulled out.

[0092] In specific applications, the prompt component can be a status prompt light or a speaker, or both. This embodiment uses the status prompt light as an example. Specifically, when the code read by the code recognition module is consistent with the preset code, the status prompt light can display a red light flashing to prompt the user that the key 30 is waiting to be pulled out; when the code read by the code recognition module is inconsistent with the preset code, the status prompt light can display a red light flashing alternately to prompt the user that the key 30 does not match the key seat; after the key 30 is pulled out of the key slot 101, the status prompt light can turn red and light up.

[0093] The steps to return the keys include:

[0094] The key 30 is inserted into the key insertion hole 101 . When the key 30 is inserted to a set position, the self-locking component can automatically lock the key 30 and simultaneously trigger the code recognition module to perform code verification on the key 30 .

[0095] In a specific application, when the key 30 is inserted into the key slot 101, the key 30 pushes the pressing end 201 of the tilting rod 20 and makes the sensing end 202 of the tilting rod 20 away from the sensing component. When the key 30 is inserted into the set position in the key slot 101, the self-locking component can automatically lock the key 30, and at the same time, the sensing end 202 is away from and triggers the sensing component, and the code recognition module is started to read the code of the key 30 and compare the code with the preset code. The key 30 pushes the pressing end 201 of the tilting rod 20 to make the sensing end 202 of the tilting rod 20 away from and trigger the sensing component. At this time, it indicates that the key 30 has been inserted into the set position of the key slot 101, and the code recognition module can start the verification of the code reading; on the contrary, if the sensing end 202 has not yet triggered the sensing component, it indicates that the key 30 has not been inserted into the key slot 101 or has not been inserted into the set position. At this time, the code recognition module will not be started, which can reduce the workload of the code recognition module. This solves the problem of virtual key lock in the prior art caused by the key not being inserted into place and the self-locking component not locking the key 30, while the coding recognition module has started verification, thereby improving the operating efficiency of the on-site monitoring device.

[0096] 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 has been returned.

[0097] Furthermore, if the code read by the code recognition module is inconsistent with the preset code, the self-locking component releases the lock on the key, and at the same time the prompting component prompts the user that the key 30 and the key seat 10 do not match.

[0098] It should be noted that, in the present embodiment, after the key 30 is inserted into the set position, the locking of the self-locking component and the reading of the code recognition module can be performed simultaneously, or the self-locking component can be locked first and the code recognition module can read the code later, and in the present embodiment, when the key 30 has not yet been inserted into the key hole 101, the self-locking component can be in a locked state, for example, before the key 30 is inserted, the telescopic pin of the self-locking component extends into the key hole 101, and after the key 30 is inserted, the key 30 pushes the telescopic pin to retract, until the key 30 is inserted into the set position, the telescopic pin extends into the key hole 101 and locks the key 30.

[0099] Alternatively, as another possible implementation of the key returning step in this embodiment, the key returning step includes:

[0100] When the key 30 is not inserted into the set position in the key slot 101 and the self-locking component is in the unlocked state, the key 30 is inserted into the key slot 101, and the key 30 pushes the pressing end 201 of the tilting rod 20 and makes the sensing end 202 of the tilting rod 20 away from the sensing component. When the key 30 is inserted into the set position in the key slot 101, the sensing end 202 is away from and triggers the sensing component, and the code recognition 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 component locks the key 30. Compared with the first possible implementation, the present implementation starts the self-locking component to lock the key 30 only after the key code verification is passed, so that it can be ensured that when the self-locking component is started, the key 30 must have been inserted into the set position of the key slot 101, and it can also solve the key virtual lock problem caused by the key not being inserted into place and the self-locking component not locking the key 30 in the prior art, and the code recognition module has started verification, thereby improving the operation efficiency of the in-situ monitoring device.

[0101] Furthermore, 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 has been returned; if the code read by the code recognition module is inconsistent with the preset code, the prompt component prompts the user that the key 30 does not match the key seat 10.

[0102] In a specific application, if the code read by the code recognition module is consistent with the preset code, the status indicator light may display a green light on, prompting the user that the key 30 has been returned; if the read code is inconsistent with the preset code, the status indicator light may display a red and green light flashing alternately, prompting that the key 30 does not match the key holder 10.

[0103] Specifically, the on-site monitoring method also includes a self-checking step.

[0104] The self-test steps include:

[0105] The code recognition module starts the code verification, reads the key code in the key slot 101, and the detection structure detects whether the key 30 is in place in the key slot 101;

[0106] If the coding recognition module reads the key code and the detection structure does not detect the presence information of the key 30, or the coding recognition module does not read the key code and the detection structure detects the presence information of the key 30, the prompt component prompts a fault message, reminding the management personnel that at least one of the coding recognition module or the detection structure has a fault and needs to be repaired in time.

[0107] The embodiment of the present invention further provides another method for monitoring the presence of a key, using the above-mentioned key management cabinet. The method for monitoring the presence of a key includes a key taking step and / or a key returning step.

[0108] The steps to access the key include:

[0109] The authorization verification module receives a request to access the key;

[0110] The control module controls the detection structure of the in-place monitoring device to detect whether there is a key 30 in the key slot 101. If the detection structure detects the key 30, the code recognition module is triggered to perform code verification on the key 30.

[0111] If the code recognition module successfully verifies the code of the key 30 , the self-locking component releases the lock on the key 30 .

[0112] Furthermore, if the detection structure detects that the key 30 is not in the key insertion hole 101 , the code recognition module is not triggered and the prompt component sends a signal that the key 30 is not in place.

[0113] Furthermore, if the code recognition module fails to verify the code of the key 30 , the self-locking component unlocks the key, and at the same time the prompt component sends a signal that the key 30 does not match the key seat 10 .

[0114] Furthermore, after the self-locking component releases the lock on the key 30 , if the key 30 stays in the key insertion hole 101 for more than a set time, the self-locking component will re-lock the key 30 .

[0115] The steps to return the keys include:

[0116] The authorization verification module receives a key return request;

[0117] The key 30 is inserted into the key insertion hole 101 of the key seat 10 . If the key 30 is inserted into the set position, the self-locking component locks the key and simultaneously triggers the code recognition module to perform code verification on the key 30 .

[0118] Furthermore, if the code recognition module fails to verify the code of the key 30, the prompt component sends a signal that the key 30 does not match the key seat 10, and at the same time the self-locking component unlocks the key 30; if the code recognition module passes the code verification of the key 30, the prompt component prompts that the key has been returned.

[0119] Specifically, the on-site monitoring method also includes a self-checking step.

[0120] The self-test steps include:

[0121] The code recognition module starts the code verification, reads the key code in the key slot 101, and the detection structure detects whether the key 30 is in place in the key slot 101;

[0122] If the coding recognition module reads the key code and the detection structure does not detect the presence information of the key 30, or the coding recognition module does not read the key code and the detection structure detects the presence information of the key 30, the prompt component prompts a fault message, reminding the management personnel that at least one of the coding recognition module or the detection structure has a fault and needs to be repaired in time.

[0123] The two key in-place monitoring methods provided in the embodiments of the present invention include a key retrieval step, a key return step and a self-checking step. On the one hand, before the key is retrieved, a detection structure is used to detect whether the key 30 is in the key slot 101, and then the key 30 is coded and verified by the coding recognition module, thereby avoiding the coding verification module from performing coding verification on an empty key slot 101, reducing the operating load of the in-place monitoring device or the key management cabinet, and increasing the service life of the equipment to a certain extent; on the other hand, when returning the key, the position of the key 30 inserted into the key slot 101 is detected by the detection structure, and after the key 30 is inserted into the set position, the key 30 is coded and locked, thereby solving the problem of virtual key locking caused by the key not being inserted into the set position and the self-locking component not locking the key, while the coding recognition module has performed coding verification in the prior art, thereby improving the accuracy and reliability of the key management of the key management cabinet; and, the self-checking step can also be used to realize automatic inspection of the equipment, timely discover equipment failures, and improve operating efficiency.

[0124] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
