Description

Technical Field

[0001] The invention relates to the technical field of electric power operation and inspection, and in particular to an intelligent key management machine for a transformer substation. Background Art

[0002] As an important substation site, the keys of each room door lock, equipment box lock, and screen cabinet door lock are stored in the substation key box. Substation keys are special tools used to open and close various equipment, doors and windows in the substation. Strict management is required to ensure the safety and reliability of substation operation.

[0003] At present, the keys of the substation are used by taking keys from a key box. When in use, the key box is opened with the master key of the key box, and the key corresponding to the key label is directly found for use. As a result, the user cannot find the required key quickly and correctly, and it takes a long time. In addition, the protection measures of the key box are poor, which may easily lead to other people taking and misusing the keys of the substation at will, causing major safety accidents. At the same time, there are also cases where the labels in the key box or the labels on the key body are lost or damaged, or there are cases where the labels on the key and the key box do not correspond. The user cannot use the key to open the corresponding door lock, which brings inconvenience to the use of the key and greatly reduces the work efficiency.

[0004] As for electronic substation smart keys, they are usually placed on charging stations. There is a lack of effective key access records, which leads to the inability to standardize the management and storage of substation keys. Substation operation and maintenance personnel are unable to accurately grasp the use of keys, which can easily cause equipment, rooms, and compartments in the station to be opened by mistake, and can also easily cause the loss of keys.

[0036] Compared with the prior art, the present invention provides a substation key intelligent management machine, which has the following beneficial effects:

[0037] 1. The present invention can directly display the location of the required key through the key intelligent management machine, which greatly reduces the time of finding the key. It can also automatically identify the consistency of the key and the storage location and label, determine the status of key return and prevention correctness, and prompt through the status display light, effectively prompting the operation and maintenance personnel and key access personnel to manage the keys reasonably, ensure the standardization of substation keys, and also improve the efficiency of the later use of keys, avoiding the loss of substation keys and the inconvenience of use.

[0038] 2. The present invention uses the second-order lock to directly unlock the box using the unpacking password when the power is on, which can ensure that only authorized personnel can access the key, thereby improving security. In the power-off state, the second-order lock core automatically performs the first-order unlocking during the spring resetting process, and the person using the lock performs the second-order unlocking with the spare key, which can effectively prevent others from opening the management machine and ensure that the key can still be used in an emergency. This provides a backup plan for unexpected situations and enhances the reliability of the system.

[0039] 3. The present invention records the use and management of substation keys. The operation and maintenance personnel are allowed to use the corresponding keys through the corresponding work tickets, which will prevent people from accidentally touching live equipment, thereby ensuring personal safety and normal operation of equipment.

[0058] The key storage module 9 is configured as a plurality of modules, which are evenly arranged in the key storage area 5, and the key storage module 9 is composed of a storage area label 12, a key status light 13, a key hanging hook 14, and a key sensing area 15;

[0059] An operation display module, which includes a display screen 2, an operation button 3 and a status display light 4 installed in the housing body 1 of the management machine, and the operation display module is used for the unpacking application of the user;

[0060] Power supply module 7, which supplies power to the management machine by directly connecting to a 220V AC power supply;

[0061] The communication module 8 includes an external communication module for sending text messages to the operation and maintenance personnel. After the operation and maintenance personnel feedback the text message password, the key access personnel enter the password to open the management machine; and

[0062] The substation key is composed of a key body 17 and a key sensing module 16 , and the substation key can be paired with the corresponding key sensing area 15 for sensing.

[0063] Based on the above technical solution, the key user first applies for unpacking in the operation display module of the substation intelligent key management machine. After entering the applicant and key number, the management machine sends an unpacking verification code SMS to the operation and maintenance personnel, and the management machine generates an unpacking record. When the power supply of the management machine is normal, after obtaining the verification code feedback from the operation and maintenance personnel, enter the correct verification code to perform the unpacking operation, and find the required substation key according to the prompt of the key status light 13. After taking it, the key status light 13 flashes as a prompt, and the status display light 4 lights up, reminding the key user to return the key as soon as possible, and close the outer shell panel 6. After the substation key is used, the key user The user applies for the return of the substation key in the operation display module of the substation intelligent key management machine. After entering the applicant and key number, the user performs the unpacking operation and returns the substation key to its original position. The key status light 13 returns to normal green and is always on. At this time, the substation key is returned to the correct position; when the substation key is returned to an incorrect position, the key status light 13 flashes red and the status display light 4 is on. This indicates that the substation key and the key sensing area 15 are incorrectly paired, and the substation key needs to be re-hung in the correct key storage area 5; after the substation key is correctly returned, the key mismatch alarm light goes out, and the key user closes the outer shell panel 6.

[0064] On the basis of the above technical scheme, the location of the required substation key can be directly displayed through the substation key intelligent management machine, which greatly reduces the time of searching for the substation key. It can also automatically identify the consistency of the substation key and the storage location and label, determine the return and prevention status of the substation key, and give prompts through the status display light 4, effectively prompting the operation and maintenance personnel and key access personnel to reasonably manage the substation key, ensure the standardization of the substation key, and improve the efficiency of the later use of the substation key, avoiding the loss and inconvenience of the substation key; in addition, by recording the use and management of the substation key, the operation and maintenance personnel can use the corresponding substation key through the corresponding work ticket, which will not cause people to accidentally touch the live equipment, ensuring personal safety and the normal operation of the equipment, and by recording the borrowers of the substation key, the use and management of the substation key are clearly defined to the person, ensuring the standardized management of the substation key.

[0065] In a possible embodiment, the status display light 4 includes a management machine operation light, a management machine unlocking light, a key mismatch warning light and a key non-returned warning light installed in the management machine housing body 1. When the access personnel find the required substation key according to the prompt of the key status light 13 and take it, after taking it, the key status light 13 flashes as a prompt, and the substation key non-returned warning light lights up, reminding the key access personnel to return the key as soon as possible; when the substation key is returned to the incorrect position, the key status light 13 flashes red, and the key mismatch warning light of the management machine lights up, then the substation key and the key sensing area 15 are paired incorrectly, and the substation key needs to be re-hung in the correct key storage area 5.

[0066] In a possible embodiment, the panel handle 10 includes a second-stage lock 101 installed on the shell panel 6 away from the hinge 11, and a lock buckle 102 is fixedly provided at a position inside the management machine shell body 1 corresponding to the second-stage lock 101. The second-stage lock 101 can be locked and unlocked in a second stage with the lock buckle 102 by a spare key 103.

[0067] It should be noted that in order to prevent the panel handle 10 from malfunctioning or the power module 7 from losing power, when the substation key is urgently needed, the secondary lock 101 and the lock buckle 102 can be unlocked by the spare key 103 to ensure that the substation key can still be used in an emergency.

[0068] In a possible implementation, the second-order lock 101 includes:

[0069] A fixing seat 1011 is fixed on the housing panel 6, and a handle 1012 is fixedly provided on the outer side of the fixing seat 1011; and

[0070] The lock hole 1013 is rotatably arranged on the outer side of the fixing seat 1011 .

[0071] In a possible implementation, the second-order lock 101 further includes:

[0072] A lock core 1014 is movably disposed inside the fixing seat 1011;

[0073] A rotating piece 1015 is rotatably disposed on the inner side of the fixing seat 1011; and

[0074] The connecting shaft 1016 has one end hinged to the lock core 1014, and the other end hinged to the rotating plate 1015, and the upper end of the connecting shaft 1016 is connected to the inner side of the fixing seat 1011 through a spring 1017, and the lower end of the connecting shaft 1016 is fixed to the output end of the micro electric cylinder body 1018, and the micro electric cylinder body 1018 is fixedly arranged on the inner side of the fixing seat 1011.

[0075] It should be explained that when the power supply of the management machine is normal, the micro-electric cylinder 1018 is in a contracted state, and the connecting shaft 1016 rotates clockwise. Fig.11 As shown, at this time, the spring 1017 is compressed, the lock core 1014 and the lock buckle 203 are completely locked. When the key is to be taken, the person who takes it enters the correct verification code in the operation display module, the micro-electric cylinder 1018 extends a fixed distance, the connecting shaft 1016 deflects counterclockwise, the lock core 1014 and the lock buckle 102 are completely separated, and the person who takes it performs the unpacking operation through the handle 1012, so that the second-order lock 101 is directly unlocked using the unpacking password when it is powered on, which can ensure that only authorized personnel can access the key, thereby improving security. After the person who takes the substation key as needed and closes the shell panel 6, the micro-electric The cylinder body 1018 contracts, the connecting shaft 1016 rotates clockwise, and the lock core 1014 and the lock buckle 203 are completely engaged. On the one hand, it can effectively prevent debris from entering the management machine, and on the other hand, it can effectively prevent others from taking the substation key in the management machine at will; when returning the key, the user applies for the return of the substation key in the operation display module, and after entering the applicant and key number, the micro-electric cylinder body 1018 extends a fixed distance, the connecting shaft 1016 deflects counterclockwise, and the lock core 1014 is completely disengaged from the lock buckle 102. The user opens the box through the handle 1012, and after returning the key, the outer shell panel 6 is closed.

[0076] In addition, when the management machine cannot supply power normally or the panel handle 10 has a circuit fault, the micro-electric cylinder 1018 is powered off, and during the process of the spring 1017 recovering its deformation, the micro-electric cylinder 1018 automatically extends, the connecting shaft 1016 deflects counterclockwise, and the lock core 1014 and the lock buckle 102 automatically achieve the first stage unlocking, such as Fig.12 shown.

[0077] In a possible embodiment, the lock core 1014 includes a sliding hook 10141 movably arranged in the fixed seat 1011, a limiting groove 10142 is opened on the sliding hook 10141 away from the rotating lock hole 1013, the limiting groove 10142 is limitedly slidably arranged in the fixed seat 1011, and a lock hole 10143 is opened on the sliding hook 10141 close to the rotating lock hole 1013.

[0078] In a possible implementation manner, the width of the lock hole 10143 is equal to the width of the locking portion of the spare key 103 .

[0079] Through the above technical solution, when the management machine cannot supply electricity normally or the panel handle 10 has a circuit failure, the lock core 1014 and the lock buckle 102 are automatically unlocked in the first stage. When the access personnel need to access the substation key, the access personnel use the spare key 103 and the turn lock hole 1013 and the lock hole 10143 to rotate 90° clockwise. After the sliding hook 10141 moves, the spring 1017 is compressed, and then the lock core 1014 is disengaged from the lock buckle 102 for the second stage unlocking, thereby ensuring that the substation key can still be used in an emergency, providing a backup plan for unexpected situations, and enhancing the reliability of the system. Finally, the access personnel opens the outer shell panel 6 through the handle 1012, accesses the substation key as needed, closes the outer shell panel 6, takes out the spare key 103, and the spring 1017 resumes its deformation, and the lock core 1014 and the lock buckle 102 return to the first stage unlocking state.

[0080] In a possible implementation, a backup power supply is further disposed in the housing body 1 of the management machine, and a switch of the backup power supply is disposed on the housing body 1 of the management machine. The backup power supply can provide a certain amount of power for the operation of the management machine.

[0081] The method for using the substation key intelligent management machine includes the following steps:

[0082] S1. Identity verification: The key user first applies for unpacking on the operation display module of the substation intelligent key management machine.
