[0004] When conducting electrification maintenance on power equipment such as railways and power grids, it is necessary to connect a grounding wire between the equipment end and the grounding end through a grounding kit to ensure safety during the operation. According to Article 7.4.9 of the "State Grid Corporation of China Electric Power Safety Work Regulations for Substations" (Q / GDW1799.1-2013), "When installing the grounding wire, the grounding end should be connected first, and then the conductor end. The grounding wire should have good contact and a reliable connection. The order of removing the grounding wire is the opposite." Most of the grounding equipment currently in use is a purely mechanical structure grounding kit. During electrification maintenance and construction, the grounding seal wire should be installed first and then the equipment end in accordance with regulations. When disassembling, the equipment end should be removed first and then the grounding end. Once an incorrect operation occurs, it may cause personal electric shock and casualties.

[0071] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings:

[0072] As shown in Figures 1 and 2, the present application provides an anti-misoperation system for a grounding set, which includes a locking mechanism and an unlocking judgment unit. The locking mechanism is used to lock the grounding clamp 100 and the grounding hook 200. The unlocking judgment unit is configured to: if D is detected 实际 <D 防误 , unlock the grounding clamp 100, and the grounding hook 200 remains locked; if it is detected that the grounding clamp 100 is connected to the ground terminal, unlock the grounding hook 200 so that the grounding hook 200 can be 防误 External connection device end. Among them, D 实际 D is the actual distance between the grounding clamp 100 and the grounding hook 200. 防误 D is the anti-error distance between the grounding clamp 100 and the grounding hook 200. 防误 Satisfaction: When D 实际 <D 防误 When the grounding clamp 100 and the grounding hook 200 are connected to the ground terminal and the equipment terminal respectively at the same time.

[0073] It should be understood that the above D 实际It refers to the actual distance when the grounding wire clamp 100 and the grounding hook 200 are connected to the grounding wire 300. The actual distance can be calculated based on the actual maximum distance between the grounding wire clamp 100 and the grounding hook 200, that is, the distance between the two points on the grounding wire clamp 100 and the grounding hook 200 that are farthest apart, or it can be the actual distance between a certain point on the calibrated grounding wire clamp 100 and a certain point on the grounding hook 200.

[0074] It should be understood that the above D 防误 It refers to the anti-error distance set by the operator based on the actual distance between the grounding terminal and the equipment terminal in a specific grounding scenario to prevent incorrect operation. 防误 It can be set to be less than the minimum distance between the ground terminal and the device terminal, that is, the distance between the two points closest to the ground terminal and the device terminal, so that: when D 实际 <D 防误 When the grounding clamp 100 and the grounding hook 200 are connected to the ground terminal and the equipment terminal respectively at the same time.

[0075] It should be understood that when the grounding clamp 100 is locked, the operator cannot perform operations on the grounding clamp 100, such as connecting or removing it. Connection or removal operations can only be performed after the grounding clamp 100 is unlocked. When the grounding hook 200 is locked, the grounding hook 200 cannot be connected to the device end. Only after the grounding hook 200 is unlocked can the device end be connected. For example, when the grounding hook 200 is locked, the grounding hook 200 is closed and cannot be opened. The grounding hook 200 can only be opened for connection after it is unlocked.

[0076] In the above implementation process, when the actual distance between the grounding wire clamp 100 and the grounding hook 200 is less than the anti-error distance, the grounding wire clamp 100 and the grounding hook 200 cannot be connected to the ground end and the equipment end respectively at the same time. The system first controls to unlock the grounding wire clamp 100. When the grounding wire clamp 100 is connected to the ground end, the grounding hook 200 is unlocked. Then the operator can pull the grounding hook 200 closer to the equipment end. Although the grounding hook 200 exceeds the anti-error distance, the grounding wire clamp 100 has been connected to the ground end. Therefore, the system will not lock the grounding hook 200, and the grounding hook 200 can be connected to the equipment end outside the anti-error distance.

[0077] In summary, when the operator installs the grounding kit, the grounding hook 200 can only be unlocked when the actual distance from the grounding clamp 100 is less than the anti-error distance and the grounding clamp 100 is connected to the grounding end. To a certain extent, it ensures the operator's operating requirements of connecting the grounding end first and then the equipment end, which can effectively prevent the operator from making incorrect connections and ensure the operator's personal safety.

[0078] Optionally, D 防误It can be set to 1%-99% of the distance between the ground terminal and the device terminal. Specifically, the anti-error distance D 防误 It can be 1%, 10%, 20%, 25%, 50%, 60%, 99% of the distance between the ground terminal and the device terminal, etc., and this embodiment of the application does not limit this. For example, if the distance between the ground terminal and the device terminal is 10m, D 防误 Set to 3m.

[0079] In one possible implementation, if D 实际 ≥D 防误 , and when the grounding clamp 100 is not connected to the grounding terminal, the grounding hook 200 is locked.

[0080] In the above implementation, according to the limitation of the anti-error distance, when the actual distance between the grounding clamp 100 and the grounding hook 200 is greater than or equal to the set anti-error distance, the grounding clamp 100 and the grounding hook 200 may be connected to the ground terminal and the device terminal respectively at the same time. Therefore, the present application is configured that when the system is started and detects that the actual distance between the grounding clamp 100 and the grounding hook 200 is greater than or equal to the set anti-error distance and the grounding clamp 100 is not connected to the ground terminal, the system controls the locking of the grounding hook 200 to prevent the operator from performing the grounding operation on the grounding kit. The grounding clamp 100 remains unlocked, and the operator can operate the grounding clamp 100 to connect to the ground terminal.

[0081] In a possible implementation, the unlocking judgment unit is configured to: if it is detected that the grounding clamp 100 is connected to the ground terminal, and D 实际 <D 防误 , unlock the grounding clamp 100.

[0082] In the above implementation process, during the operation of installing the grounding set, when the grounding clamp 100 is connected to the grounding terminal and the distance between the grounding hook 200 and the grounding clamp 100 is less than the anti-error distance, the grounding clamp 100 remains unlocked, that is, when there is a problem with the connection between the grounding clamp 100 and the grounding terminal, such as the wrong connection position of the grounding terminal, or insufficient connection, the grounding clamp 100 can be removed from the grounding terminal and reconnected. Since the grounding hook 200 is within the anti-error range at this time and cannot be connected to the equipment end, the grounding clamp 100 remains unlocked, which will not cause the operator's erroneous operation and allows the operator to adjust the connection between the grounding clamp 100 and the grounding terminal.

[0083] In addition, during the operation of removing the grounding set, when the grounding wire clamp 100 is connected to the grounding end and the grounding hook 200 is within the anti-error range, it can be ensured that the grounding hook 200 has been removed from the equipment end. At this time, the system unlocks the grounding wire clamp 100, which can effectively ensure the operating specifications of removing the grounding hook 200 first and then the grounding wire clamp 100, thereby ensuring the personal safety of the operator.

[0084] In a possible implementation, the unlocking judgment unit is configured to: if it is detected that the grounding clamp 100 is connected to the ground terminal, and D 实际 ≥D 防误 When the grounding clamp 100 is locked.

[0085] In the above implementation process, during the operation of installing the grounding kit, when the grounding clamp 100 is connected to the ground terminal and the distance between the grounding hook 200 and the grounding clamp 100 is greater than or equal to the anti-error distance, the grounding hook 200 can be connected to the device end. If the grounding clamp 100 is detached from the ground terminal for some reason before the grounding hook 200 is connected to the device end, and the grounding clamp 100 is disconnected from the ground terminal, if the operator fails to notice that the grounding clamp 100 is disconnected from the ground terminal and connects the grounding hook 200, it may cause danger. Therefore, the present application provides that when the grounding clamp 100 is connected to the ground terminal and the distance between the grounding hook 200 and the grounding clamp 100 is greater than or equal to the anti-error distance, the system locks the grounding clamp 100, which can effectively prevent the grounding clamp 100 from accidentally detaching from the ground terminal and causing a dangerous situation.

[0086] In addition, during the operation of removing the grounding set, when the distance between the grounding hook 200 and the grounding clamp 100 is greater than the anti-error distance, the grounding hook 200 may not have been removed from the equipment end. Therefore, the system controls and locks the grounding clamp 100, which can prevent the operator from removing the grounding clamp 100 before the grounding hook 200 is removed.

[0087] In a possible implementation, the unlocking judgment unit is configured to: if it is detected that the grounding clamp 100 is connected to the ground terminal, and D 实际 <D 防误 When the ground hook 200 is locked.

[0088] In the above implementation process, during the operation of removing the grounding suit, when the grounding hook 200 is removed from the equipment end and approaches the grounding clamp 100 and moves into the anti-error range, the system controls the grounding clamp 100 to unlock. If the grounding clamp 100 is unlocked and removed from the grounding end at this time, the grounding hook 200 still remains unlocked, that is, the grounding clamp 100 and the grounding hook 200 are in the unlocked state at the same time, it is possible that the grounding hook 200 and the grounding clamp 100 are approaching the equipment end at the same time, and the two are kept within the anti-error distance. The grounding clamp 100 is not connected to the grounding end, and the operator connects the grounding hook 200 to the equipment end. Therefore, the present application is set to lock the grounding hook 200 when the grounding clamp 100 is connected to the grounding end and the distance between the grounding hook 200 and the grounding clamp 100 is less than the anti-error distance.

[0089] In a possible implementation, the unlocking judgment unit is configured to: if it is detected that the grounding clamp 100 is connected to the ground terminal, and D 实际 ≥D 防误 , unlock the ground hook 200.

[0090] In the above implementation process, during the installation of the grounding kit, when the grounding wire clamp 100 is connected to the grounding end and the grounding hook 200 is moved out of the anti-error distance, the grounding hook 200 is unlocked, and the operator can pull the grounding hook 200 outside the anti-error distance and connect it to the equipment end.

[0091] In one possible embodiment, the unlocking judgment unit includes a distance detection unit and a control unit. The distance detection unit is used to detect the actual distance between the grounding wire clamp 100 and the grounding hook 200; the control unit is used to control the locking mechanism to lock or unlock according to the detection result of the distance detection unit.

[0092] In the above implementation process, when the distance detection unit detects that the actual distance between the grounding wire clamp 100 and the grounding hook 200 is less than, equal to or greater than the anti-error distance, it sends a distance signal to the control unit, and the control unit controls the unlocking and locking of the grounding wire clamp 100 and the grounding hook 200 according to the distance signal.

[0093] In one possible embodiment, the distance detection unit includes a first Bluetooth module and a second Bluetooth module. The first Bluetooth module is mounted on the grounding clamp 100. The second Bluetooth module is mounted on the grounding hook 200 and is configured to connect to the first Bluetooth module within a range less than the error prevention distance. The distance detection unit is configured to send a connection signal to the control unit when the first Bluetooth module connects to the second Bluetooth module; and to send a disconnection signal to the control unit when the first Bluetooth module disconnects from the second Bluetooth module.

[0094] In the above implementation process, Bluetooth is a radio technology that supports short-range communication of devices. It has the characteristics of being able to achieve communication connection within the communication range and disconnecting the communication connection outside the communication range. The present application uses this characteristic of Bluetooth to realize the judgment of the distance between the grounding wire clamp 100 and the grounding hook 200. When the first Bluetooth module is connected to the second Bluetooth module, it means that the actual distance between the grounding wire clamp 100 and the grounding hook 200 is less than the anti-error distance. At this time, the first Bluetooth module and / or the second Bluetooth module sends a connection signal to the control unit, and the control unit performs corresponding control actions according to the connection signal. When a Bluetooth module is disconnected from the second Bluetooth module, it means that the actual distance between the grounding wire clamp 100 and the grounding hook 200 is greater than or equal to the anti-error distance. At this time, the first Bluetooth module and / or the second Bluetooth module sends a connection signal to the control unit, and the control unit performs corresponding control actions according to the connection signal. The present application can realize unlocking judgment and locking judgment through the above method.

[0095] In a possible implementation, the distance detection unit is a distance measuring sensor, which is used to measure the distance between the grounding clamp 100 and the grounding hook 200 in real time.

[0096] In the above implementation process, a distance measuring sensor is used to detect the distance between the grounding clamp 100 and the grounding hook 200 in real time, and a distance signal is sent to the controller, which performs corresponding control actions according to the detected distance.

[0097] Optionally, the above-mentioned ranging sensor can be an infrared ranging sensor, an ultrasonic ranging sensor, a laser ranging sensor, etc., which is not limited in the embodiment of the present application.

[0098] Optionally, the distance detection unit may also adopt other distance measurement products, such as a radio frequency rangefinder, etc., which is not limited in the embodiment of the present application.

[0099] In a possible implementation, the unlocking judgment unit further includes a connection detection unit; the connection detection unit is connected to the control unit and is used to detect whether the grounding clamp 100 is connected to the ground terminal.

[0100] In the above implementation, after the connection detection unit detects that the grounding clamp 100 is connected to the ground terminal, it sends a corresponding signal to the control unit. After receiving the signal, the control unit combines other signals to control the unlocking of the grounding hook 200 or the locking of the grounding clamp 100. After the connection detection unit detects that the grounding clamp 100 is disconnected from the ground terminal, it sends a corresponding signal to the control unit to lock the grounding hook 200, etc.

[0101] In one possible embodiment, as shown in Figures 3 and 4 , a grounding clamp 100 includes a first clamping block 110 and a second clamping block 120. The second clamping block 120 is configured to move toward the first clamping block 110 until it clamps the grounding terminal after the first clamping block 110 contacts the grounding terminal. The connection detection unit includes a detection switch disposed on the contact surface of the second clamping block 120 when the second clamping block 120 clamps the grounding terminal.

[0102] In the above implementation, based on the structure and connection operation of the grounding clamp 100, the grounding clamp 100 and the grounding terminal are clamped together when the second clamping block 120 contacts the grounding terminal. Therefore, a detection switch is provided on the second clamping block 120. When the grounding clamp 100 and the grounding terminal are clamped together, the detection switch opens and sends a signal to the control unit. When the grounding clamp 100 and the grounding terminal are disengaged, the detection switch closes and sends a signal to the control unit. The control unit then performs corresponding control actions based on the above signal.

[0103] Optionally, the detection switch may be a contact switch, an electric switch, a magnetic switch, etc., which is not limited in the embodiment of the present application.

[0104] In one possible embodiment, the locking mechanism includes a first locking mechanism, which includes a first drive unit and a first locking assembly. The first drive unit is disposed on the grounding clamp 100; the first locking assembly is connected to an output end of the first drive unit and is configured to lock or unlock the grounding clamp 100 under the action of the first drive unit.

[0105] In one possible embodiment, as shown in Figure 4, the first locking assembly is a driving screw 130 that drives the clamping portion of the grounding clamp 100 to move, and the first driving unit is a driving element 140 that drives the driving screw 130 to rotate. The controller controls the first driving unit to lock or unlock to lock or unlock the grounding clamp 100.

[0106] In the above implementation, the clamping portion of the grounding clamp 100 is electrically driven by the drive screw 130. Therefore, the drive screw 130 can be used as the first locking component, and the drive element 140 can be used as the first drive unit. The controller controls the unlocking or locking of the drive screw 130 by turning the motor on or off. Therefore, the first locking mechanism of the present application utilizes the structure of the grounding clamp 100 itself to achieve locking and unlocking of the grounding clamp 100, which can effectively simplify the system structure.

[0107] Optionally, the driving element 140 is a motor or an electromagnet, etc., which is not limited in the embodiment of the present application.

[0108] Optionally, the present application may also separately provide a first locking mechanism in addition to the structure of the grounding clamp 100 itself. For example, a limiter may be provided in the travel path of the clamping block, and the first drive unit may be a motor that drives the limiter to extend or retract. When the limiter is extended, the clamping block is stuck and cannot move forward, thereby achieving locking. When the limiter is retracted, the clamping block can move normally for connection or removal operations.

[0109] In one possible embodiment, the locking mechanism includes a second locking mechanism 230, which includes a second drive unit and a second locking assembly 240. The second drive unit is disposed on the ground hook 200. The second locking assembly 240 is connected to the output end of the first drive unit and is configured to lock or unlock the ground hook 200 under the control of the first drive unit.

[0110] In one possible embodiment, as shown in Figures 5 to 8, the grounding hook 200 includes an insulating rod 210 and a sleeve 220 rotatably mounted on the insulating rod 210. The sleeve 220 controls the opening and closing of the grounding hook 200 by rotating relative to the insulating rod 210. A second drive unit is fixedly connected to the insulating rod 210, and a second locking assembly 240 is connected to the output end of the second drive unit to tighten or release the sleeve 220 under the drive of the second drive unit.

[0111] Specifically, the structure of the second locking mechanism 230 can be actually designed according to the specific structure of the grounding hook 200 .

[0112] In a possible embodiment, the anti-misoperation system of the grounding kit further includes an alarm mechanism and an alarm judgment unit. The alarm mechanism is provided on at least one of the grounding clamp 100, the grounding wire 300, and the grounding hook 200. The alarm judgment unit is configured to: if D 实际 ≥D 防误 , the alarm agency starts the alarm. Among them, D 实际 D is the actual distance between the grounding clamp 100 and the grounding hook 200. 防误 is the set anti-error distance, D 防误 When the distance between the grounding clamp 100 and the grounding hook 200 is less than D 防误 When the grounding clamp 100 and the grounding hook 200 are connected to the ground terminal and the equipment terminal respectively at the same time.

[0113] It should be understood that the above D 实际It refers to the actual distance when the grounding wire clamp 100 and the grounding hook 200 are connected to the grounding wire 300. The actual distance can be calculated based on the actual maximum distance between the grounding wire clamp 100 and the grounding hook 200, that is, the distance between the two points on the grounding wire clamp 100 and the grounding hook 200 that are farthest apart, or it can be the actual distance between a certain point on the calibrated grounding wire clamp 100 and a certain point on the grounding hook 200.

[0114] It should be understood that the above D 防误 It refers to the anti-error distance set by the operator based on the actual distance between the grounding terminal and the equipment terminal in a specific grounding scenario to prevent incorrect operation. 防误 It can be set to be less than the minimum distance between the ground terminal and the device terminal, that is, the distance between the two points closest to the ground terminal and the device terminal, so that: when D 实际 <D 防误 When the grounding clamp 100 and the grounding hook 200 are connected to the ground terminal and the equipment terminal respectively at the same time.

[0115] In the above implementation process, according to the limiting conditions of the anti-error distance, when the actual distance between the grounding clamp 100 and the grounding hook 200 is greater than or equal to the set anti-error distance, the grounding clamp 100 and the grounding hook 200 may be connected to the ground terminal and the equipment terminal respectively at the same time. Therefore, the present application is configured such that when the system is started, if it detects that the actual distance between the grounding clamp 100 and the grounding hook 200 is greater than or equal to the set anti-error distance, the alarm mechanism activates an alarm, reminding the operator to check whether the grounding clamp 100 is connected to the ground terminal. The operator then decides whether to connect or remove the grounding hook 200 based on the inspection results. By setting the anti-error distance, the present application issues an alarm when the actual distance between the grounding clamp 100 and the grounding hook 200 is greater than the anti-error distance, reminding the operator to check the connection of the grounding clamp 100, thereby preventing the operator from operating incorrectly and causing danger to a certain extent.

[0116] Optionally, D 防误 It can be set to 1%-99% of the distance between the ground terminal and the device terminal. Specifically, the anti-error distance D 防误 It can be 1%, 10%, 20%, 25%, 50%, 60%, 99% of the distance between the ground terminal and the device terminal, etc., and this embodiment of the application does not limit this. For example, if the distance between the ground terminal and the device terminal is 10m, D 防误 Set to 3m.

[0117] Optionally, the alarm mechanism may provide an alarm prompt through sound, light, color, text, or other means that can be recognized by the operator.

[0118] When the operator checks and finds that the grounding clamp 100 is already connected to the ground terminal, or the grounding clamp 100 is not connected to the ground terminal and the operator reconnects it, the alarm can be manually released by the operator or the system can control the alarm to be released.

[0119] The system control alarm release scheme may be: the alarm judgment unit is configured to: if D is detected 实际 ≥D 防误 , and when the grounding wire clamp 100 is connected to the grounding terminal, the alarm mechanism releases the alarm.

[0120] In the above scheme, the grounding wire clamp 100 is connected to the grounding end, and the actual distance between the grounding hook 200 and the grounding wire clamp 100 is greater than or equal to the set anti-error distance. At this time, the conditions for the grounding hook 200 to be safely connected to the equipment end are met, the alarm mechanism cancels the alarm, and the operator can pull the grounding hook 200 to safely connect to the equipment end.

[0121] In a possible implementation manner, the alarm determination unit is configured to: if D is detected 实际 <D 防误 , and when the grounding clamp 100 is not connected to the grounding terminal, the alarm mechanism starts the alarm.

[0122] In the above implementation process, when the actual distance between the grounding clamp 100 and the grounding hook 200 is less than the anti-error distance, but the grounding clamp 100 is not installed on the ground terminal, it is possible that the grounding hook 200 and the grounding clamp 100 simultaneously approach the equipment end, and both remain within the anti-error distance. The operator may mistakenly connect the grounding hook 200 to the ground terminal when the grounding clamp 100 is not connected to the ground terminal. Therefore, the present application provides that when the actual distance between the grounding clamp 100 and the grounding hook 200 is less than the anti-error distance, but the grounding clamp 100 is not installed on the ground terminal, the alarm is activated to remind the operator to check whether the grounding clamp 100 is connected to the ground terminal, and decide whether to connect or remove the grounding hook 200 based on the result.

[0123] In a possible implementation manner, the alarm determination unit is configured to: if D is detected 实际 <D 防误 , and when the grounding clamp 100 is connected to the grounding terminal, the alarm mechanism releases the alarm.

[0124] During the above implementation process, when the actual distance between the grounding wire clamp 100 and the grounding hook 200 is less than the anti-error distance and the grounding wire clamp 100 is connected to the grounding end, the conditions for the grounding hook 200 to be safely connected to the equipment end are met, the alarm mechanism cancels the alarm, and the operator can pull the grounding hook 200 to safely connect to the equipment end.

[0125] In a fourth aspect, the present application further provides a computer-readable storage medium storing instructions, which, when executed by a processor, executes any of the above-mentioned methods for preventing misoperation of the grounding kit.

[0126] The processor may include one or more processing cores. The processor utilizes various interfaces and lines to connect various parts of the entire server, and executes various server functions and processes data by running or executing instructions, programs, code sets, or instruction sets stored in memory, as well as calling data stored in memory. Optionally, the processor may be implemented in the form of at least one hardware component selected from digital signal processing (DSP), field-programmable gate array (FPGA), and programmable logic array (PLA). The processor may integrate one or a combination of a central processing unit (CPU), a graphics processing unit (GPU), and a modem. The CPU primarily processes the operating system, user interface graphics, and application programs; the GPU is responsible for rendering and drawing the content to be displayed on the display; and the modem is used to handle wireless communications. It is understood that the modem may not be integrated into the processor and may be implemented separately on a single chip.
