Description

Technical Field

[0001] The present invention relates to the technical field of borrowing three types of keys in a power plant, and in particular to a self-service device for borrowing three types of keys and its usage method. Background Art

[0002] At the site of a power plant, there are various devices installed at different locations. There are multiple different protective doors in the entire production site of the power plant to prevent unauthorized personnel from entering and causing equipment shutdown or even serious safety accidents. Therefore, at the site of the power plant, different personnel need to borrow relevant keys to enter different areas or open a certain device.

[0003] Currently, the personnel borrowing keys at the power plant site are mainly divided into operating personnel and maintenance personnel. The operating personnel need to monitor the operation of the power plant daily and make timely records. The maintenance personnel need to regularly complete maintenance work or promptly repair when equipment fails to ensure the normal operation of the power plant equipment. Currently, the keys borrowed by the operating personnel and maintenance personnel are mainly divided into three types, namely: access control cards; E-key passes; various unlocking keys, which are mainly used for general equipment room doors, outdoor switchyard interval doors, switch cabinet doors, etc. Currently, during daily patrols and unit maintenance, there are frequent borrowings of access control cards and E-key passes. In this case, it often occurs that the person in charge of the work fails to return the access control card or E-key pass in a timely manner due to various reasons, ultimately resulting in the loss of access control cards and E-key passes.

[0004] To solve the above situation, the operation department implements borrowing registration procedures for access control cards, E-key passes, etc. This method requires the borrower to register in the access control card borrowing record book and return it after use. It requires the borrower to have strong self-discipline and register in a timely manner before and after use. At the same time, it also requires the operating personnel to carry out supervision work for a long time to ensure the reliability of this method. During the actual implementation of borrowing registration and return registration, this method is cumbersome and there is a risk of missing or misrecording. Especially during unit maintenance, due to the increased number of borrowings of access control cards and E-key passes, the workload suddenly increases, resulting in the inability to correctly and timely execute the access control card borrowing registration procedures. Frequently, access control cards are lost after maintenance, posing a certain hidden danger to safe production. Summary of the Invention

[0085] Embodiment 1

[0086] A self-service three-category key borrowing device includes a cabinet body 1, a key placing and taking component 2, a front cabinet door 3, and an intelligent borrowing component 4. The cabinet body 1 is made of aluminum alloy material. The interior of the cabinet body 1 is divided into two parts by a baffle. The left side is the key placement area, and the right side is the intelligent borrowing component placement area. The front cabinet door 3 is rotatably connected to the left front position of the cabinet body 1. The cabinet door 5 of the intelligent borrowing component placement area is opened on the right side of the cabinet body 1 and is connected by a snap connection method.

[0087] In this embodiment, as Figure 1As shown, the front cabinet door 3 is rotatably connected to the left front position of the cabinet body 1. The front cabinet door 3 is used for borrowers to open the front cabinet door 3 to pick up or return keys when borrowing or returning keys. The cabinet door 3 of the intelligent borrowing component placement area is opened on the right side of the cabinet body 1 and is connected by a buckle connection method, which is convenient for the maintenance of the borrowing device. Open the cabinet door 5 from the side to check the intelligent borrowing component 4. The designs of the front cabinet door 3 and the cabinet door 5 at different positions realize their respective functions. The self-service three-category key borrowing device as a whole places the keys on the key pick-up and placement component 2, and the intelligent borrowing component 4 identifies the permissions of borrowers and operators, and respectively adopts different key borrowing processes to complete the borrowing and returning processes. Using this device, operators and maintenance personnel can self-service borrow three categories of keys, avoiding the inefficiencies and key losses in the traditional registration system, and realizing the normal and efficient circulation of the key borrowing system in the power plant.

[0088] The intelligent borrowing component 4 includes an integrated circuit 41, a power module 42, a camera acquisition area 43, a display screen 44, a borrowing button 45, a return button 46, and a fingerprint acquisition area 47. The integrated circuit 41 and the power module 42 are located on the right side of the cabinet body 1. The power interface of the power module 42 is located on the back of the cabinet body 1. The camera acquisition area 43 is located above the front of the cabinet body 1. The display screen 44 is located below the camera acquisition area 43. The borrowing button 45 and the return button 46 are located below the display screen 44. Among them, the borrowing button 45 is located on the left side of the return button 46. The fingerprint acquisition area 47 is located below the borrowing button 45 and the return button 46.

[0089] In this embodiment, as Figure 3 shown, the intelligent borrowing component 4 realizes the self-service borrowing of three categories of keys through the function selection module on the display screen in cooperation with the borrowing button 45 and the return button 46, and grants different borrowing permissions through the fingerprint acquisition area 47 and the camera acquisition area 43 to realize the whole-process management. The intelligent borrowing component 4 solves the problems existing in the traditional key borrowing, can improve the working efficiency of key borrowing, avoid the occurrence of key loss, and at the same time realize the intelligentization of the key management work in the power plant.

[0090] In this embodiment, as Figure 3As shown, the integrated circuit 41 serves as the core of the self-service three-category key borrowing device, controlling the self-service borrowing process of the device. The power supply module 42 provides electrical energy for the device. The camera acquisition area 43 is used for collecting the face information of relevant personnel. The fingerprint acquisition area 47 is used for collecting the fingerprint data of relevant personnel. The display screen 44 is used for displaying relevant information and data. Borrowers can obtain borrowing information according to the prompts of relevant information to complete the borrowing. The borrowing button 45 and the return button 46 are used to assist the borrowing process and the return process. Through this intelligent borrowing component 4, the self-service borrowing of three-category keys in the power plant is completed.

[0091] Specifically, the key placement and extraction component 2 includes a placement board 21 and key insertion holes 22. The placement board 21 is fixedly installed at the middle position on the left side inside the cabinet 1. There are multiple key insertion holes 22, which are evenly distributed in front of the placement board 21. Each key insertion hole 22 is provided with a pressure sensor 221, and an indicator light 222 is arranged above the key insertion hole 22. The pressure sensor 221 and the indicator light 222 are connected to the integrated circuit 41 of the intelligent borrowing component 4 from the back of the placement board 21.

[0092] In this embodiment, as Figure 2 shown, the placement board 21 is used to fix the key insertion holes 22 and is fixedly installed at the middle position on the left side inside the cabinet 1 to ensure that all keys are inside the cabinet 1. The key insertion holes 22 are used to place various keys used in the power plant. Generally, a key usually includes a key body, a connecting rope, and an information card. One end of the key body is inserted into the key insertion hole 22, one end of the connecting rope is connected to the other end of the key body, and the other end of the connecting rope is connected to the information card.

[0093] Specifically, the indicator light 222 has three states, namely:

[0094] When there is a key in the key insertion hole 22, it is green;

[0095] When the key is taken out from the key insertion hole 22, it is red;

[0096] During the borrowing authorization period of the key in the key insertion hole 22, it is a green light flashing at a fixed frequency.

[0097] In this embodiment, as Figure 1 、 Figure 3As shown in the figure, the pressure sensor 221 inside the key insertion hole 22 is used to identify whether a key is inserted into the key insertion hole 22. The pressure sensor 221 and the indicator light 222 are used as a group. When there is a key inserted into the key insertion hole 22, at this time, due to the insertion of the key, the corresponding pressure sensor 211 senses the pressure signal from the key and sends this pressure signal to the integrated circuit 41. The integrated circuit 41 sends a signal to the indicator light 222 according to this pressure signal. At this time, the indicator light 22 lights up in a green state. When there is no key inserted into the key insertion hole 22, at this time, due to the removal of the key, the corresponding pressure sensor 211 does not sense the pressure signal from the key. The integrated circuit 41 sends a signal to the indicator light 222. At this time, the indicator light 22 lights up in a red state. When the integrated circuit 41 receives the borrowing signal from the intelligent borrowing component 4, at this time, during the key borrowing authorization period, the indicator light 22 flashes a green light at a fixed frequency. Through the setting of these three states of the indicator light 222, it is convenient to timely understand the key borrowing situation and improve the key management efficiency of the power plant.

[0098] In this embodiment, this self-service three-category key borrowing device does not need to be connected to the network during use. By storing information locally, it avoids the occurrence of network-related security risks and ensures the safety of use.

[0099] Embodiment 2

[0100] Specifically, a fixing bracket 11 is provided on the back of the cabinet body 1 by means of threaded connection.

[0101] In this embodiment, as Figure 2 shown, the fixing bracket 11 is provided on the back of the cabinet body 1. When this self-service three-category key borrowing device needs to be installed on the wall, at this time, first fix the fixing bracket 11 on the back of the cabinet body 1 with bolts, and then fix the cabinet body 1 on the wall. When this self-service three-category key borrowing device does not need to be installed on the wall, directly place this device on the ground. The overall use is convenient and flexible, and the applicable range is wide.

[0102] Embodiment 3

[0103] Specifically, the front cabinet door 3 adopts a glass protection door. A door handle 31 and an induction lock 32 are installed on the right side of the front cabinet door 3. The induction lock 32 is connected to the integrated circuit 41 of the intelligent borrowing component 4.

[0104] In this embodiment, as Figure 3 shown, the induction lock 32 is provided for opening the front cabinet door 3. When the induction lock 32 receives the borrowing signal from the integrated circuit 41, the induction lock 32 opens, and the key is taken out to complete the borrowing. After the borrowing is completed, the induction lock 32 closes in time.

[0105] In this embodiment, the front cabinet door 3 is a glass protection door, which can clearly observe the borrowing situation of the keys on the placement board 21.

[0106] Specifically, the display screen 44 is a touch screen, which includes five modules, namely, the borrowing module 441 for operators, the borrowing module 442 for maintenance personnel, the return module 443, the information inquiry module 444, and the identity setting module 445.

[0107] The borrowing module 441 for operators is used for borrowing keys corresponding to operators.

[0108] The borrowing module 442 for maintenance personnel is used for borrowing keys corresponding to maintenance personnel.

[0109] The return module 443 is used for the return of keys after the corresponding personnel have completed using them.

[0110] The information inquiry module 444 is used for inquiring about the borrowing situation of all keys in the device.

[0111] The identity setting module 445 is used for inputting the information of borrowing personnel and setting permissions.

[0112] In this embodiment, as Figure 6 shown, the display screen 44 is set as a touch screen, which is convenient for the operation of borrowing personnel. At the same time, five function modules are set on the display screen 44, with clear logic and simple operation. The borrowing of keys can be directly realized through touch control, which improves the working efficiency of key borrowing in the power plant. An information inquiry module 444 is set in the function module of the display screen 44, which can inquire about the borrowing records of the corresponding keys at any time, trace back to the relevant parts in time when problems occur. If there is a situation where the keys are not returned after borrowing, the borrowing records and photos can be consulted in time to confirm the identity information of the borrower immediately, ensuring the smooth operation of the power plant site. An identity setting module 445 is set in the function module of the display screen 44. Since the operators on the power plant site need to carry out daily monitoring work and have the highest frequency of key borrowing, while the maintenance personnel need a certain period for on-site equipment maintenance and have a relatively lower frequency of key borrowing compared with the operators, there are certain differences in the borrowing methods of the two types of personnel. Therefore, the borrowing module 442 for maintenance personnel and the borrowing module 441 for operators are set corresponding to different personnel to improve efficiency.

[0113] In this embodiment, the borrowing records of the device can be cleared regularly. The records are usually saved for 6 months, which can effectively improve the storage efficiency.

[0114] Embodiment 4

[0115] Specifically, the power supply module 42 is also provided with a storage battery 421, which is connected to the integrated circuit 41 to provide electrical energy for the borrowing device.

[0116] In this embodiment, the power supply module 42 is provided with a storage battery 421, which can continuously supply power to the self-service three-category key borrowing device in the event of an accidental power outage in the power plant, avoiding emergencies caused by the inability to borrow keys in an emergency and enabling timely response.

[0117] Specifically, the induction lock 32 can also be opened by a magnetic card or a mechanical key.

[0118] In this embodiment, in order to avoid the impact caused by the inability to open the self-service borrowing device in case of an accident, a magnetic card or a mechanical key is provided for the induction lock 32 to assist in opening, further ensuring the normal and orderly use of the self-service key borrowing device.
