Description

Technical Field

[0001] This invention relates to the field of power distribution technology, and specifically to a terminal power consumption information collection system, and more particularly to a terminal power consumption information collection system based on security components. Background Technology

[0002] The terminal electricity consumption information collection system is a key data node deployed on the user side, such as in residential areas, factories, or commercial buildings. Its core function is to collect, process, and upload electricity consumption information, forming a crucial bridge connecting user smart meters and the power grid master station system. The collection terminals within the system serve as data aggregation and communication hubs, collecting, processing, and monitoring electricity users' consumption information in real time. It is a core system requiring high-level protection, as its internal data is related to electricity billing, user privacy, and power grid security.

[0003] Different maintenance personnel, such as meter readers, repairmen, and system administrators, should have different data access and equipment operation permissions. This ensures that only strictly authorized personnel can maintain or verify designated terminals through controlled and secure processes, thus providing necessary maintenance access capabilities while preventing the risks of unauthorized access and misoperation. However, existing electricity information collection terminals lack hierarchical authorization and effective restriction mechanisms, making it easy for unauthorized personnel to access terminal data outside their jurisdiction or perform misoperations, posing risks of data leakage and operational security. Summary of the Invention

[0004] This invention proposes a terminal electricity consumption information collection system based on security components. Its purpose is to solve the problem that existing electricity consumption information collection terminals cannot achieve hierarchical authorization and have the risk of unauthorized operation.

[0005] The technical solution of this invention is as follows: A terminal power consumption information collection system based on security components includes a cabinet and cabinet doors. It also includes a security lock assembly, which consists of a lock body fixed to the cabinet door and a lock base fixed to the cabinet; the lock body integrates a password input device for authentication and an electrically controlled bolt with controlled action; The cabinet is equipped with a main control unit, which is electrically connected to the password input device and the electric lock tongue. The main control unit integrates a processing module responsible for logic control, a password module for storing verification passwords, and an access control module for storing operation permissions. The cabinet is also equipped with a connection management device, which includes an instruction input device and an electrical connection switching component. The instruction input device is electrically connected to the main control unit. The processing module calls the password module to verify the unlock password received from the password input device and queries the permission module to determine the operator's permissions. After both verification and permission determination are passed, the processing module controls the security lock component to unlock. The processing module receives the permission instruction from the instruction input device, calls the permission module to verify the instruction, and after the verification is passed, controls the electrical connection switching component to establish an electrical connection with a target acquisition terminal.

[0006] As a further improvement of the present invention, the connection management device is a female socket disposed between two adjacent sets of terminal systems; the instruction input device is disposed on the female socket; and the electrical connection switching component is disposed inside the female socket.

[0007] As a further improvement of the present invention, the terminal system includes one or more acquisition terminals, each of which is connected to multiple terminal cables; the electrical connection switching component includes a cable organizer corresponding to each acquisition terminal; the cable organizer is provided with conductive contact strips that are connected to and correspond to the terminal cables.

[0008] As a further improvement of the present invention, the electrical connection switching assembly further includes an L-shaped sliding bracket that is slidably mounted on the female seat via a vertical guide mechanism, and an insulating transmission component is slidably mounted on the L-shaped sliding bracket; a magnetic component is provided between the L-shaped sliding bracket and the female seat housing for driving the L-shaped sliding bracket and the insulating transmission component to move up and down, so as to realize the switching of the vertical channel.

[0009] As a further improvement of the present invention, the magnetic component includes a permanent magnet and an electromagnet. The permanent magnet is fixed to the bottom surface of the horizontal section of the L-shaped sliding bracket, and the electromagnet is fixed to the bottom wall of the female base housing. A spring is connected between the horizontal section of the L-shaped sliding bracket and the female base housing. The spring is located on the outside of the magnetic component and is used to drive the L-shaped sliding bracket to reset after power failure.

[0010] As a further improvement of the present invention, the insulating transmission component is embedded with a T-shaped conductive connector, which is used to realize the electrical connection between the calibrator and the conductive contact strip.

[0011] As a further improvement of the present invention, the vertical section of the T-shaped conductive connector penetrates through the insulating transmission component, and connection terminals are formed on the top and bottom walls of the insulating transmission component respectively. The number of T-shaped conductive connectors corresponds to the number of conductive contact strips of the cable organizer. The horizontal section of the T-shaped conductive connector is electrically connected to the electrical connector installed on the outside of the female housing for connecting the calibrator through a flexible connecting wire.

[0012] As a further improvement of the present invention, the electrical connection switching assembly further includes a drive mechanism that drives the insulating transmission component to move horizontally along the L-shaped sliding bracket.

[0013] As a further improvement of the present invention, the drive mechanism includes a servo motor, a gear is drivenly connected to the output shaft of the servo motor, and a rack that meshes with the gear is fixed on the insulated transmission component.

[0014] As a further improvement of the present invention, the command input device is a touch screen command input device or a keypad command input device; and / or, the password input device is a touch screen password input device or a keypad password input device.

[0015] Compared with the prior art, the present invention has the following advantages: (1) This system integrates a password input device and an electric lock tongue safety lock component, combined with the permission module and password module in the main control unit, to verify the identity and match the permissions of the operator. Only after the permission verification is passed can the cabinet door be opened and the subsequent electrical connection process be started. This eliminates the possibility of unauthorized operation from both physical access and electrical connection levels, and significantly improves the system security.

[0016] (2) Based on user permissions, this system automatically locks the range of accessible acquisition terminals and drives the T-shaped conductive connector to precisely connect to the conductive contact strip of the target acquisition terminal through the coordinated action of the electrical connection switching component in the vertical and horizontal directions. This mechanism ensures that only one authorized physical connection can be established at a time, which satisfies the flexibility of operation and maintenance and avoids the risk of misconnection or unauthorized access.

[0017] (3) This system uses an electromagnet to control the lifting and lowering of the insulated transmission components to achieve vertical channel selection; and uses a servo motor to drive the rack and pinion transmission to achieve precise horizontal positioning. This electromechanical linkage method is responsive and reliable. Under the logic control of the main control unit, it achieves rapid and stable switching of electrical connections, improving the overall reliability and operation and maintenance efficiency of the system.

[0018] (4) By setting up displacement sensors, this system can realize closed-loop control and feedback of the horizontal position of the insulated transmission components, further improving the accuracy and reliability of connection alignment. The use of stainless steel cabinets and doors enhances the protection level and service life of the equipment in complex environments such as outdoors. Attached Figure Description

[0021] The technical solutions and effects of the present invention will be described in detail below with reference to specific embodiments and accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] like Figure 1 The image shows an embodiment of a terminal power consumption information collection system based on a security component according to the present invention. This embodiment includes a cabinet 1, a cabinet door 2 hinged to the cabinet 1, and a security lock assembly. The cabinet 1 and cabinet door 2 are preferably made of stainless steel to improve protective performance.

[0023] The security lock assembly includes a lock body 3 fixed to the cabinet door 2 and a lock base 4 fixed to the cabinet body 1. The lock body 3 integrates a password input device for authentication and a controlled electronic bolt. The password input device can be either a keypad type or a touchscreen type.

[0024] Cabinet 1 houses a main control unit, which is electrically connected to the password input device and the electric lock tongue. The main control unit integrates a processing module responsible for logic control, an access control module for storing operator permissions, and a password module for storing verification passwords.

[0025] The cabinet 1 contains multiple terminal systems for data acquisition installed from top to bottom. Each terminal system includes a data acquisition terminal 5. Each data acquisition terminal 5 is connected to multiple terminal cables 6 arranged sequentially in the left-right direction.

[0026] Combination Figure 2 and Figure 3In the illustrated embodiment, two sets of terminal systems are installed inside the cabinet 1, each set containing two data acquisition terminals 5 arranged side-by-side. A female connector 9 for connection management is installed between adjacent sets of terminal systems. The female connector 9 is equipped with a command input device. This command input device is electrically connected to the main control unit and is used to transmit user operation commands to the processing module. Optionally, it can be electrically connected via a communication bus. Preferably, the command input device is connected to the main control unit via an RS-485 communication bus. The command input device can be a touchscreen or a button type. One or more electrical connectors 11 are installed on the outer side of the female connector 9 for connecting external calibrators or debugging equipment.

[0027] The female connector 9 is internally connected to an electrical connection switching assembly controlled by the main control unit. This electrical connection switching assembly includes cable organizers 7 corresponding to each acquisition terminal 5, and these cable organizers 7 are fixed to the housing of the female connector 9. Figure 4 As shown, each cable organizer 7 has one or more cable positioning slots for organizing and fixing the terminal cables 6. One or more conductive contact strips 8 arranged sequentially in the front-to-back direction are fixed to the side of the cable organizer 7 facing the inside of the female connector 9; the side of the cable organizer 7 facing the outside of the female connector 9 is used to connect the terminal cables 6 leading from the corresponding acquisition terminal 5. After each terminal cable 6 is gathered and fixed by the cable positioning slots, its conductive core wire is electrically connected to the corresponding conductive contact strip 8.

[0028] A vertical guide mechanism is fixed to the bottom wall of the female base 9, and an L-shaped sliding bracket 14 is slidably connected to the guide mechanism. The L-shaped sliding bracket 14 includes a horizontal section, and a vertical section is fixed to the rear side of the horizontal section, forming a right-angle sliding channel between the two. The insulating transmission component 12 is slidably disposed in the right-angle sliding channel and can move in the horizontal direction. A magnetic component is provided between the horizontal section of the L-shaped sliding bracket 14 and the housing of the female base 9. The magnetic component includes a permanent magnet 17 and an electromagnet 18. The permanent magnet 17 is fixed to the bottom surface of the horizontal section of the L-shaped sliding bracket 14, and the electromagnet 18 is fixed to the bottom wall of the housing of the female base 9. A spring 19 is connected between the horizontal section of the L-shaped sliding bracket 14 and the housing of the female base 9. The spring 19 is disposed outside the magnetic component and is used to drive the L-shaped sliding bracket 14 to reset after power failure.

[0029] A servo motor 15 is mounted on the front side of the horizontal section of the L-shaped sliding bracket 14. An insulated transmission component 12 is slidably connected within the right-angle sliding channel between the servo motor 15 and the vertical section. Figure 5 As shown, a gear 16 is connected to the output shaft of the servo motor 15. The gear 16 meshes with a rack fixed on the insulated transmission component 12, driving the insulated transmission component 12 to move left and right along the horizontal section of the L-shaped sliding bracket 14. Optionally, a displacement sensor is installed on the insulated transmission component 12 to detect its horizontal position in real time and feed it back to the main control unit to achieve precise positioning.

[0030] The insulated transmission component 12 is embedded with T-shaped conductive connectors 13, the number of which corresponds to the conductive contact strips 8 of the cable organizer 7. The vertical section of each T-shaped conductive connector 13 penetrates the insulated transmission component 12, forming connection terminals on the top and bottom walls of the insulated transmission component 12. The horizontal section of the T-shaped conductive connector 13 is reliably connected to the electrical connector 11 mounted on the outside of the housing of the female connector 9 via a flexible connecting wire 10, together forming an electrical path. The magnetic force of the electromagnet 18 is designed to be sufficiently large to ensure a stable and reliable electrical contact pressure between the T-shaped conductive connector 13 and the conductive contact strip 8 when connected.

[0031] The working principle of this embodiment is as follows: One or more access permissions are pre-stored in the permission module, with each permission defining the range of data acquisition terminals 5 that are allowed to operate. Multiple sets of passwords are pre-stored in the password module, each uniquely corresponding to one access permission. Maintenance personnel first enter their personal password through the password input device on the security lock component. The main control unit's processing module calls the password module for verification. If verification fails, the security lock component remains locked, and the process terminates. If verification succeeds, the processing module retrieves the list of operation permissions corresponding to that password from the permission module, i.e., the range of data acquisition terminals 5 that are allowed to access, and then controls the electric lock tongue to unlock the cabinet door 2.

[0032] After opening cabinet door 2, personnel select or enter the corresponding number of target acquisition terminal 5 on the instruction input device of mother seat 9. Upon receiving this instruction, the processing module immediately performs an access verification to determine whether the target acquisition terminal 5 is within the access list obtained in the first step. If it is included in the access list, the verification passes and proceeds to the next step. If it is not included, the verification fails, and the main control unit does not perform any mechanical actions.

[0033] After verification, the processing module calculates the required coordinates of the electrical connection switching component based on the target acquisition terminal 5's number, such as the row and column number. The main control unit generates two sets of control commands: commands to control lifting and commands to control left and right movement. The energization or de-energization of electromagnet 18 drives the insulated transmission component 12 to rise and fall, selecting the corresponding vertical channel. If the target acquisition terminal 5 is located above, electromagnet 18 is energized to generate a magnetic force that repels the permanent magnet 17, pushing the L-shaped sliding bracket 14 upward against the resistance of spring 19, allowing the insulated transmission component 12 to enter the upper channel; if the target acquisition terminal 5 is located below, electromagnet 18 is de-energized, and under the restoring force of spring 19, the L-shaped sliding bracket 14 moves downward, allowing the insulated transmission component 12 to enter the lower channel.

[0034] After the vertical channel is selected, the main control unit controls the servo motor 15 to drive the gear 16 rack and pinion transmission mechanism, so that the insulated transmission component 12 moves horizontally, and the T-shaped conductive connector 13 on the insulated transmission component 12 is connected to the conductive contact strip 8 of the cable organizer 7 at the target position.

[0035] Once the insulated transmission component 12 is in place, an electrical path is established when the connecting terminal of the T-shaped conductive connector 13 makes stable contact with the conductive contact strip 8 of the corresponding target cable organizer 7. At this time, the calibrator can access the target acquisition terminal 5.

[0036] Through the above mechanism, in the initial and standby states, all T-shaped conductive connectors 13 remain separated from the conductive contact strip 8. The main control unit only initiates a unique physical electrical connection when both user permissions and commands are valid, thus completely eliminating the possibility of unauthorized access at the hardware level. Throughout the process, the system strictly adheres to the "single-point connection" principle. If the user's input command fails permission verification, the main control unit will refuse to execute any mechanical action, thereby fundamentally preventing unauthorized operations.

[0037] Taking the example of allowing access only to the upper left and lower right corners of the terminal, the workflow of this system embodiment is explained as follows: Connecting to the lower right terminal: After the permission verification is passed, the processing module controls the electromagnet 18 to be de-energized, so that the insulated transmission component 12 is positioned in the lower channel; then the servo motor 15 is driven to move the insulated transmission component 12 horizontally to the right, so that the connection terminal at the lower end of the T-shaped conductive connector 13 contacts the conductive contact strip 8 of the lower right cable organizer 7, and a connection is established.

[0038] Connecting to the upper left terminal: After the permission verification is passed, the processing module controls the electromagnet 18 to be energized, driving the insulated transmission gear to be positioned in the upper channel; then it drives the servo motor 15 to move the insulated transmission component 12 horizontally to the left, so that the connection terminal at the upper end of the T-shaped conductive connector 13 makes stable contact with the conductive contact strip 8 of the upper left cable organizer 7, and establishes a connection.

[0039] It should be noted that, as will be apparent to those skilled in the art, the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics thereof. The scope of the present invention is defined by the claims rather than the foregoing description.
