Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of registration devices, in particular to an intelligent management device for substation keys. Background Art
[0002] As an important node in the power system, the operation safety of a substation is directly related to the stability and reliability of the power grid. To achieve standardized operation and safety management, substations usually need to uniformly manage various types of equipment keys to avoid potential safety hazards caused by key loss, abuse, or misoperation. Uniform key management can ensure that only authorized personnel can access critical equipment, thereby improving the safety level of the substation.
[0003] The traditional key management method relies on manual registration, which is prone to recording errors, and the borrowing and returning processes are cumbersome. In view of this, the comparative document CN222622484U proposes an intelligent key box for substation external borrowing key management. By setting a rotating plate in the storage box body and respectively arranging flipping boxes on the front side and the rear side of the rotating plate, the front side and the rear side of the rotating plate can be switched to face the outside, and keys can be stored and taken in different flipping boxes to facilitate people to find and take keys.
[0004] However, the comparative document uses a method of matching an electromagnetic lock core with a lock port to fix the flipping box and controls the electromagnetic lock core using a contact sensor. When the electromagnetic lock core is disengaged from the lock port, the flipping box is unlocked; only when the electromagnetic lock core is aligned with the lock port and extends into the lock port can the flipping box be locked. In actual use, if the flipping box is not pushed back in place, resulting in the contact sensor not being triggered, or if the flipping box is offset after the contact sensor is triggered, it may cause the flipping box to fail to lock tightly, thus affecting the safety of the keys.

Detailed Embodiments
[0022] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0023] Embodiment: An intelligent management device for substation keys, as Figures 1-5 shown, includes: a cabinet 1; a control terminal 2 fixedly installed on the right side of the cabinet 1, the control terminal 2 integrating a multi-modal biometric recognition system, with a built-in face recognition module, voiceprint recognition module, iris recognition module, palmprint recognition module, fingerprint recognition module, and password instruction module, realizing user identity authentication through multi-dimensional biometric collection and comparison. In actual use, any one of the above verification methods or a combination of multiple methods can be used for identity authentication; a fixing plate 3 fixedly installed on the front side of the cabinet 1; a plurality of cabinet openings 5 arranged in an array on the fixing plate 3, with a total of 5*7 cabinet openings 5; a placement frame 6 slidably installed in each cabinet opening 5, each placement frame 6 being used to store keys 4 in a classified manner; a first electromagnet 7 fixedly installed in each cabinet opening 5, when the placement frame 6 is completely placed in the cabinet opening 5, the placement frame 6 will contact and magnetically connect with the first electromagnet 7; a bottom plate 12 movably arranged inside the cabinet 1, and a driving member for controlling the movement of the bottom plate 12 is arranged inside the cabinet 1; an electric push rod 13 fixedly installed on the bottom plate 12, the bottom plate 12 moves the electric push rod 13 to the rear of each placement frame 6, and the control terminal 2 is electrically connected to the electric push rod 13 to control the telescopic movement of the rod end of the electric push rod 13; a second electromagnet 14 fixedly installed on the rod end of the electric push rod 13, the second electromagnet 14 can move to contact and magnetically connect with the placement frame 6. The first electromagnet 7 and the second electromagnet 14 adopt the working mode of being energized for excitation and demagnetized when powered off, and the on-off states of both are regulated by the control terminal 2.
[0024] The driving member includes: a first mounting frame 8 fixedly installed inside the cabinet 1, the first mounting frame 8 being arranged at the rear side of the fixing plate 3; a first electric slide rail 9 fixedly installed on the first mounting frame 8; a second mounting frame 10 fixedly installed on the control end of the first electric slide rail 9, the first electric slide rail 9 controlling the up and down movement of the second mounting frame 10; a second electric slide rail 11 fixedly installed on the second mounting frame 10, the bottom plate 12 being fixedly installed on the control end of the second electric slide rail 11, the second electric slide rail 11 controlling the left and right movement of the bottom plate 12. The first electric slide rail 9 and the second electric slide rail 11 are both electrically connected to the control terminal 2, so that the two are controlled by the control terminal 2 to operate.
[0025] When using this device, the keys 4 are loaded into each placement frame 6, and the first electromagnet 7 locks each placement frame 6; the control terminal 2 is used to collect the user's identity information, and the user's identity information is paired with each placement frame 6.
[0026] After completing the above preparatory work, when the user needs to take the key 4, the user uses the control terminal 2 for identity verification. After confirming that the user's identity information is correct, the control terminal 2 moves the electric push rod 13 to the rear side of the placement frame 6 paired with the user's identity information, controls the second electromagnet 14 to be energized, and the first electromagnet 7 in the cabinet opening 5 where the placement frame 6 is located to be de-energized. Then the first electromagnet 7 unlocks the placement frame 6. Subsequently, the rod end of the electric push rod 13 is extended, the second electromagnet 14 is magnetically connected to the placement frame 6, and the placement frame 6 is pushed outwards. At this time, the user can take out the key 4 corresponding to his identity. After taking the key 4, the control terminal 2 is used to control the placement frame 6 to move back into the cabinet opening 5, control the first electromagnet 7 to be energized to lock the placement frame 6, control the second electromagnet 14 to be de-energized to release its connection with the placement frame 6, and the control terminal 2 also records the position where the electric push rod 13 is controlled to move and the frequency of the controlled movement, so as to record the usage situation of the key 4 for the management and control of the key 4 and promptly discover abnormal usage of the key 4. Similarly, after using the key 4, the above identity verification is also carried out, the placement frame 6 is pushed out, and finally after the key 4 is put back into the placement frame 6, the placement frame 6 is moved back into the cabinet opening 5 for locking.
[0027] As Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 shown, the intelligent management device further includes: a rotating plate 15 rotatably installed in the placement frame 6; a slot plate 20 fixedly installed on the rotating plate 15 and adapted to the key 4, and the slot plate 20 restricts the key 4 to accurately position the placement position of the key 4; an inductor 16 fixedly installed on the rotating plate 15, and the inductor 16 is electrically connected to the control terminal 2. Each key 4 is provided with a unique RFID tag, and the inductor 16 will identify these RFID tags and transmit the identification information to the control terminal 2. The control terminal 2 is provided with a timing module. When the inductor 16 detects that the key 4 is taken away, the inductor 16 sends an electrical signal to the control terminal 2 to start timing; when the inductor 16 detects that the key 4 is put back, the inductor 16 sends an electrical signal to the control terminal 2 again to terminate timing; a torsion spring 17 fixedly installed between the placement frame 6 and the rotating plate 15, and the torsion spring 17 is sleeved on the shaft of the rotating plate 15. The torsion spring 17 is used to apply an additional force to the rotating plate 15 so that the rotating plate 15 can be better controlled to rotate back; a convex rod 18 fixedly installed at the rear part on the right side of the rotating plate 15; a chute plate 19 fixedly installed in the cabinet opening, and the end of the convex rod 18 passes through the placement frame 6 and is slidably installed with the chute plate 19, and the front end of the chute plate 19 is inclined downwards.
[0028] As Figure 3 and Figure 6As shown in the figure, the intelligent management device further includes: a ball 202 slidably mounted on the inner side wall of the card slot plate 20; a return spring 201 fixedly mounted between the ball 202 and the card slot plate 20. The return spring 201 acts on the key 4 through the ball 202, thereby stably fixing the key 4 within the card slot plate 20.
[0029] During the process when the user retrieves the key 4 and manipulates the placement frame 6 to move forward, the relative displacement between the placement frame 6 and the chute plate 19 will cause the convex rod 18 to slide within the chute plate 19. The chute plate 19 guides the convex rod 18 to generate a downward displacement. Due to the lever principle, the rotating plate 15 rotates, and its front end moves upward, making the key 4 closer to the opening of the placement frame 6, thus facilitating the retrieval of the key 4. After the key 4 is taken away, the sensor 16 loses the inductive connection with the key 4. At this time, the sensor 16 transmits a signal to the control terminal 2. On the one hand, it enables the control terminal 2 to manipulate the placement frame 6 to retract backward into the cabinet opening 5. In particular, during this process, the control terminal 2 will transmit a delayed signal to avoid the placement frame 6 accidentally injuring the user's hand. On the other hand, it enables the control terminal 2 to start recording the time when the key 4 is taken away. When the user finishes using the key 4 and returns the key 4 to the placement frame 6, and the user places the key 4 within the card slot plate 20, at this time, the sensor 16 inducts with the key 4. First, the control terminal 2 compares whether the RFID tag of the key 4 is correct according to the information transmitted by the sensor 16 to determine whether the key 4 is correctly returned. After confirming that the information is correct, the control terminal 2 stops timing and controls the placement frame 6 to retract backward. During the process, the rotating plate 15 is reversed, and the ball 202 cooperates with the return spring 201 to fix the key 4, preventing the key 4 from detaching from the card slot plate 20 and affecting the sensor 15. If the key 4 is incorrectly returned, the sensor 16 transmits a signal to the control terminal 2, causing it to issue an alarm to remind the user until the key 4 is correctly returned, and then the placement frame 6 can be controlled to retract backward. This device uses the sensor 16 to transmit signals to enable the control terminal 2 to record the usage duration of each key 4, improving the management effect of the key 4 by increasing the data for controlling the key 4. Moreover, when the usage duration of the key 4 is abnormal, for example, the key 4 should be used and returned on the same day, but the recorded usage duration exceeds 24 hours, or the usage duration exceeds the specified duration, the control terminal 2 will feedback the abnormal duration data to the user's intelligent terminal to prompt the user to return the key 4 in time, thereby improving the security of the key 4.
[0030] As Figures 1-3 shown in the figure, the intelligent management device further includes: an identification card 22 fixedly mounted on each placement frame 6, and the identification card 22 is used to mark the information of the key 4 stored in each placement frame 6 for the purpose of controlling the key 4; a warning light 21 fixedly mounted on each placement frame 6, and the warning light 21 is used to indicate the position of the corresponding placement frame 6 when taking and placing the key 4 for convenient use of this device.
