[0069] The embodiments of the present application will be further described in detail below with reference to the accompanying drawings:

[0070] As Figure 1 With Figure 2 As shown in the drawings, the present application provides an anti-misoperation system for grounding set, which comprises a locking mechanism and an unlocking judgment unit, the locking mechanism is used for locking the grounding clamp 100 and the grounding hook 200. The unlocking judgment unit is configured to: if it is detected that the grounding clamp 100 is connected to the grounding end, the grounding hook 200 is unlocked to enable the grounding hook 200 to be connected to the equipment end outside the distance D 实际 <D 防误 , the grounding clamp 100 is unlocked, and the grounding hook 200 remains locked; if it is detected that the grounding clamp 100 is connected to the grounding end, the grounding hook 200 is unlocked to enable the grounding hook 200 to be connected to the equipment end outside the distance D 防误 , the grounding clamp 100 is unlocked, and the grounding hook 200 remains locked; if it is detected that the grounding clamp 100 is connected to the grounding end, the grounding hook 200 is unlocked to enable the grounding hook 200 to be connected to the equipment end outside the distance D 实际 , the grounding clamp 100 is unlocked, and the grounding hook 200 remains locked; if it is detected that the grounding clamp 100 is connected to the grounding end, the grounding hook 200 is unlocked to enable the grounding hook 200 to be connected to the equipment end outside the distance D 防误 , the grounding clamp 100 is unlocked, and the grounding hook 200 remains locked; if it is detected that the grounding clamp 100 is connected to the grounding end, the grounding hook 200 is unlocked to enable the grounding hook 200 to be connected to the equipment end outside the distance D 防误 , the grounding clamp 100 is unlocked, and the grounding hook 200 remains locked; if it is detected that the grounding clamp 100 is connected to the grounding end, the grounding hook 200 is unlocked to enable the grounding hook 200 to be connected to the equipment end outside the distance D 实际 , the grounding clamp 100 is unlocked, and the grounding hook 200 remains locked; if it is detected that the grounding clamp 100 is connected to the grounding end, the grounding hook 200 is unlocked to enable the grounding hook 200 to be connected to the equipment end outside the distance D 防误 , the grounding clamp 100 is unlocked, and the grounding hook 200 remains locked; if it is detected that the grounding clamp 100 is connected to the grounding end, the grounding hook 200 is unlocked to enable the grounding hook 200 to be connected to the equipment end outside the distance D

[0071] It should be understood that the above D 实际Actual distance refers to the actual distance between the grounding clamp 100 and the grounding hook 200 when the grounding clamp 100 and the grounding hook 200 are connected to the grounding wire 300. The actual distance can be calculated from the actual farthest distance between the grounding clamp 100 and the grounding hook 200, that is, the distance between the two points farthest apart on the grounding clamp 100 and the grounding hook 200, or the actual distance between a certain point on the grounding clamp 100 and a certain point on the grounding hook 200.

[0072] It should be understood that the above D 防误 Preventive error distance refers to the distance set by the operator to prevent incorrect operation according to the actual distance between the grounding end and the device end in a specific grounding scene. 防误 It can be set to be less than the minimum distance between the grounding end and the device end, that is, the distance between the two points closest to each other, so that when D 实际 <D 防误 When D

[0073] It should be understood that when the grounding clamp 100 is in a locked state, the operator cannot operate the grounding clamp 100, such as connection or disassembly operation, and only after the grounding clamp 100 is unlocked can the connection or disassembly operation be performed. When the grounding hook 200 is in a locked state, the grounding hook 200 cannot be connected to the device end, and only after the grounding hook 200 is unlocked can the device end be connected, such as the locked state of the grounding hook 200 being closed and unable to open, and the grounding hook 200 can be opened to connect after being unlocked.

[0074] In the above implementation process, when the actual distance between the grounding clamp 100 and the grounding hook 200 is less than the preventive error distance, the grounding clamp 100 and the grounding hook 200 cannot simultaneously connect the grounding end and the device end, respectively. The system first controls the grounding clamp 100 to be unlocked, and when the grounding clamp 100 is connected to the grounding end, the grounding hook 200 is then unlocked. The operator can then pull the grounding hook 200 closer to the device end. Although the grounding hook 200 exceeds the preventive error distance, the grounding clamp 100 has already been connected to the grounding end, so the system will not lock the grounding hook 200, and the grounding hook 200 can connect the device end outside the preventive error distance.

[0075] As can be seen from the above, when installing the grounding set, the operator limits the grounding hook 200 to be unlocked only when the actual distance between the grounding clamp 100 and the grounding hook 200 is less than the preventive error distance and the grounding clamp 100 is connected to the grounding end, which to some extent ensures the operation requirement that the operator connects the grounding end first and then the device end, and effectively prevents the operator from making incorrect connections and ensures the safety of the operator.

[0076] Optionally, D 防误The anti-misoperation distance D can be set as 1%-99% of the distance between the grounding end and the equipment end. 防误 The anti-misoperation distance D can be 1%, 10%, 20%, 25%, 50%, 60%, 99% of the distance between the grounding end and the equipment end, and the embodiments of the present application do not limit the anti-misoperation distance D. For example, if the distance between the grounding end and the equipment end is 10 m, the anti-misoperation distance D can be set as 3 m. 防误 The anti-misoperation distance D can be set as 3 m.

[0077] In a possible implementation, if it is detected that the distance between the grounding clamp 100 and the grounding hook 200 is greater than or equal to the anti-misoperation distance D, and the grounding clamp 100 is not connected to the grounding end, the grounding hook 200 is locked. 实际 ≥D 防误 In a possible implementation, if it is detected that the distance between the grounding clamp 100 and the grounding hook 200 is greater than or equal to the anti-misoperation distance D, and the grounding clamp 100 is not connected to the grounding end, the grounding hook 200 is locked.

[0078] In the above implementation process, according to the limitation condition of the anti-misoperation distance, when the actual distance between the grounding clamp 100 and the grounding hook 200 is greater than or equal to the set anti-misoperation distance, the grounding clamp 100 and the grounding hook 200 can be connected to the grounding end and the equipment end respectively. Therefore, the present application sets that when the system is started, it is detected that the actual distance between the grounding clamp 100 and the grounding hook 200 is greater than or equal to the set anti-misoperation distance, and the grounding clamp 100 is not connected to the grounding end, the system controls the grounding hook 200 to be locked, so as to avoid the ground set operation of the operator. The grounding clamp 100 remains in the unlocked state, and the operator can operate the grounding clamp 100 to be connected to the grounding end.

[0079] In a possible implementation, the unlocking judgment unit is configured to: if it is detected that the grounding clamp 100 is connected to the grounding end, and the distance between the grounding clamp 100 and the grounding hook 200 is less than the anti-misoperation distance D, the grounding clamp 100 is unlocked. 实际 <D 防误 In a possible implementation, the unlocking judgment unit is configured to: if it is detected that the grounding clamp 100 is connected to the grounding end, and the distance between the grounding clamp 100 and the grounding hook 200 is less than the anti-misoperation distance D, the grounding clamp 100 is unlocked.

[0080] In the above implementation process, in the operation of installing the grounding set, when the grounding clamp 100 is connected to the grounding end, and the distance between the grounding clamp 100 and the grounding hook 200 is less than the anti-misoperation distance, the grounding clamp 100 remains in the unlocked state. That is, when the connection of the grounding clamp 100 to the grounding end is problematic, such as the grounding end is connected to the wrong position or the connection is insufficient, the grounding clamp 100 can be removed from the grounding end and reconnected. Since the grounding hook 200 is within the anti-misoperation range at this time and cannot be connected to the equipment end, the grounding clamp 100 remains unlocked, which will not cause the operator to make a mistake, and the operator can adjust the connection of the grounding clamp 100 to the grounding end.

[0081] In addition, in the operation of dismounting the grounding set, when the grounding clamp 100 is connected with the grounding end and the grounding hook 200 is within the anti-misoperation range, it can be ensured that the grounding hook 200 has been dismounted from the equipment end, at this time, the system only unlocks the grounding clamp 100, which can effectively ensure the operation specification of dismounting the grounding hook 200 first and then dismounting the grounding clamp 100, and guarantee the personal safety of the operator.

[0082] In a possible implementation, the unlocking judging unit is configured to: if it is detected that the grounding clamp 100 is connected with the grounding end and D 实际 ≥ D 防误 , lock the grounding clamp 100.

[0083] In the above implementation process, in the operation of mounting the grounding set, when the grounding clamp 100 is connected with the grounding end and the distance between the grounding hook 200 and the grounding clamp 100 is greater than or equal to the anti-misoperation distance, at this time, the grounding hook 200 can be connected with the equipment end, if the grounding clamp 100 is disengaged from the grounding end due to some reasons before the grounding hook 200 is connected with the equipment end, and the operator does not notice that the grounding clamp 100 is disconnected with the grounding end, the operator may cause danger when connecting the grounding hook 200. Therefore, the application is provided: when the grounding clamp 100 is connected with the grounding end and the distance between the grounding hook 200 and the grounding clamp 100 is greater than or equal to the anti-misoperation distance, the system locks the grounding clamp 100, which can effectively prevent the danger caused by the accidental disengagement of the grounding clamp 100 from the grounding end.

[0084] In addition, in the operation of dismounting the grounding set, when the distance between the grounding hook 200 and the grounding clamp 100 is greater than the anti-misoperation distance, the grounding hook 200 can not have been dismounted from the equipment end, therefore the system controls to lock the grounding clamp 100, which can avoid that the operator dismounts the grounding clamp 100 first when the grounding hook 200 has not been dismounted.

[0085] In a possible implementation, the unlocking judging unit is configured to: if it is detected that the grounding clamp 100 is connected with the grounding end and D 实际 < D 防误 , lock the grounding hook 200.

[0086] In the above implementation process, in the operation of dismounting the grounding set, when the grounding hook 200 is dismounted from the equipment end and moves into the anti-misoperation distance by approaching the grounding clamp 100, the system controls the grounding clamp 100 to be unlocked. If the grounding clamp 100 is unlocked and dismounted from the grounding end at this time, the grounding hook 200 still remains in the unlocked state, that is, the grounding clamp 100 and the grounding hook 200 are simultaneously in the unlocked state, and it is possible that the grounding hook 200 and the grounding clamp 100 simultaneously approach the equipment end and remain in the anti-misoperation 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 application is configured 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-misoperation distance.

[0087] In a possible implementation, the unlocking judgment unit is configured to unlock the grounding hook 200 if it is detected that the grounding clamp 100 is connected to the grounding end and D 实际 ≥ D 防误 .

[0088] In the above implementation process, in the process of installing the grounding set, the grounding hook 200 is unlocked again when the grounding clamp 100 is connected to the grounding end and the grounding hook 200 moves out of the anti-misoperation distance, so that the operator can connect the grounding hook 200 to the equipment end outside the anti-misoperation distance.

[0089] In a possible implementation, the unlocking judgment unit includes a distance detection unit and a control unit. The distance detection unit is configured to detect the actual distance between the grounding clamp 100 and the grounding hook 200. The control unit is configured to control the locking mechanism to be locked or unlocked according to the detection result of the distance detection unit.

[0090] In the above implementation process, when the distance detection unit detects that the actual distance between the grounding clamp 100 and the grounding hook 200 is less than, equal to, or greater than the anti-misoperation distance, a distance signal is sent to the control unit, and the control unit controls the unlocking and locking of the grounding clamp 100 and the grounding hook 200 according to the distance signal.

[0091] In a possible implementation, the distance detection unit includes a first Bluetooth module and a second Bluetooth module. The first Bluetooth module is arranged on the grounding clamp 100. The second Bluetooth module is arranged on the grounding hook 200 and is configured to be connected to the first Bluetooth module within a distance less than the anti-misoperation distance. The distance detection unit is configured to send a connection signal to the control unit when the first Bluetooth module and the second Bluetooth module are connected, and send a disconnection signal to the control unit when the first Bluetooth module and the second Bluetooth module are disconnected.

[0092] In the implementation process, Bluetooth is a wireless radio technology supporting short-distance communication of devices, and has the characteristics of realizing communication connection within the communication range and disconnecting the communication connection outside the communication range. The application utilizes the characteristics of Bluetooth to realize the distance judgment between the grounding clamp 100 and the grounding hook 200. When the first Bluetooth module is connected with the second Bluetooth module, it indicates that the actual distance between the grounding clamp 100 and the grounding hook 200 is less than the anti-misoperation 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 makes a corresponding control action according to the connection signal. When the first Bluetooth module is disconnected with the second Bluetooth module, it indicates that the actual distance between the grounding clamp 100 and the grounding hook 200 is greater than or equal to the anti-misoperation 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 makes a corresponding control action according to the connection signal. The unlocking judgment and the locking judgment can be realized through the above-mentioned manner.

[0093] In a possible implementation, the distance detection unit is a distance measuring sensor, and the distance measuring sensor is used to measure the distance between the grounding clamp 100 and the grounding hook 200 in real time.

[0094] In the implementation process, the distance measuring sensor is used to detect the distance between the grounding clamp 100 and the grounding hook 200 in real time, and sends a distance signal to the controller, and the controller makes a corresponding control action according to the detected distance.

[0095] Optionally, the distance measuring sensor can be an infrared distance measuring sensor, an ultrasonic distance measuring sensor, a laser distance measuring sensor, etc., and the embodiments of the application are not limited thereto.

[0096] Optionally, the distance detection unit can also use other distance measuring products, such as a radio frequency distance measuring instrument, etc., and the embodiments of the application are not limited thereto.

[0097] In a possible implementation, the unlocking judgment unit further includes a connection detection unit; the connection detection unit is connected with the control unit, and is used to detect whether the grounding clamp 100 is connected with the grounding end.

[0098] In the implementation process, after the connection detection unit detects that the grounding clamp 100 is connected with the grounding end, the connection detection unit sends a corresponding signal to the control unit, and the control unit controls the unlocking of the grounding hook 200 or the locking of the grounding clamp 100, etc. after receiving the signal in combination with other signals. After the connection detection unit detects that the grounding clamp 100 is disconnected with the grounding end, the connection detection unit sends a corresponding signal to the control unit, and the grounding hook 200 is locked, etc.

[0099] In a possible implementation, as Figure 3 and Figure 4As shown, the grounding wire clamp 100 comprises a first clamping block 110 and a second clamping block 120, the second clamping block 120 is used to move the first clamping block 110 until the first clamping block 110 clamps the grounding terminal after the first clamping block 110 contacts the grounding terminal. The connection detection unit comprises a detection switch, the detection switch is arranged on the contact surface of the second clamping block 120 when the second clamping block 120 clamps the grounding terminal.

[0100] In the above implementation process, according to the structure of the grounding wire clamp 100 and the connection operation, the grounding wire clamp 100 clamps the grounding terminal after the second clamping block 120 contacts the grounding terminal, so the detection switch is arranged on the second clamping block 120. When the grounding wire clamp 100 clamps the grounding terminal, the detection switch is opened and sends a signal to the control unit, and when the grounding wire clamp 100 is separated from the grounding terminal, the detection switch is closed and sends a signal to the control unit, and the control unit makes corresponding control action according to the above signal.

[0101] Optionally, the detection switch can be a contact switch, an electric switch, a magnetic switch, etc., and the embodiments of the present application are not limited thereto.

[0102] In a possible implementation, the locking mechanism comprises a first locking mechanism, the first locking mechanism comprises: a first driving unit and a first locking component. The first driving unit is arranged on the grounding wire clamp 100; the first locking component is connected with the output end of the first driving unit, and is used to lock or unlock the grounding wire clamp 100 under the driving of the first driving unit.

[0103] In a possible implementation, as shown in the drawings, Figure 4 the first locking component is a driving screw rod 130 for driving the clamping part of the grounding wire clamp 100 to move, the first driving unit is a driving element 140 for driving the driving screw rod 130 to rotate, and the controller controls the first driving unit to lock or unlock, so as to lock or unlock the grounding wire clamp 100.

[0104] In the above implementation process, the clamping part of the grounding wire clamp 100 is driven by the electrically driven driving screw rod 130, so the driving screw rod 130 can be used as the first locking component, the driving element 140 can be used as the first driving unit, and the controller can control the unlocking or locking of the driving screw rod 130 by controlling the opening or closing of the motor. Therefore, the first locking mechanism of the present application utilizes the structure of the grounding wire clamp 100 itself to realize the locking and unlocking of the grounding wire clamp 100, which can effectively simplify the structure of the system.

[0105] Optionally, the driving element 140 is a motor or an electromagnet, and the embodiments of the present application are not limited thereto.

[0106] Optionally, the first locking mechanism can be provided separately from the structure of the grounding clamp 100, for example, a limiting member is provided on the travel path of the clamping block, and the first driving unit is a motor that drives the limiting member to extend or retract. When the limiting member extends, the clamping block is blocked and cannot travel, thereby achieving locking. When the limiting member retracts, the clamping block can normally travel to perform connection or disconnection operations.

[0107] In one possible implementation, the locking mechanism includes a second locking mechanism 230, which includes a second driving unit and a second locking assembly 240. The second driving unit is provided on the grounding hook 200. The second locking assembly 240 is connected to the output end of the first driving unit, and is used to lock or unlock the grounding hook 200 under the driving of the first driving unit.

[0108] In one possible implementation, as shown in Figures 5 to 8 The grounding hook 200 includes an insulating rod 210 and a sleeve 220 rotatably arranged 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. The second driving unit is fixedly connected to the insulating rod 210, and the second locking assembly 240 is connected to the output end of the second driving unit, and is used to abut or release the sleeve 220 under the driving of the second driving unit.

[0109] Specifically, the structure of the second locking mechanism 230 can be actually designed according to the specific structure of the grounding hook 200.

[0110] In one possible implementation, the anti-misoperation system of the grounding set 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 start the alarm mechanism to alarm if it is detected that D 实际 ≥D 防误 . Wherein, D 实际 is the actual distance between the grounding clamp 100 and the grounding hook 200, D 防误 is the set anti-misoperation distance, and D 防误 satisfies: when the distance between the grounding clamp 100 and the grounding hook 200 is less than D 防误 , the grounding clamp 100 and the grounding hook 200 cannot be connected to the grounding end and the device end, respectively.

[0111] It should be understood that the above D 实际Actual distance refers to the actual distance between the grounding clamp 100 and the grounding hook 200 when the grounding clamp 100 and the grounding hook 200 are connected to the grounding wire 300. The actual distance can be calculated from the actual farthest distance between the grounding clamp 100 and the grounding hook 200, that is, the distance between the two points farthest apart on the grounding clamp 100 and the grounding hook 200, or the actual distance between a certain point on the grounding clamp 100 and a certain point on the grounding hook 200.

[0112] It should be understood that the above D 防误 Error prevention distance refers to the error prevention distance set by the operator according to the actual distance between the grounding end and the device end in a specific grounding scene. 防误 It can be set to be less than the minimum distance between the grounding end and the device end, that is, the distance between the two points closest to each other, so that when D 实际 <D 防误 The grounding clamp 100 and the grounding hook 200 cannot be simultaneously connected to the grounding end and the device end, respectively.

[0113] In the above implementation process, according to the limitation condition of the error prevention distance, when the actual distance between the grounding clamp 100 and the grounding hook 200 is greater than or equal to the set error prevention distance, the grounding clamp 100 and the grounding hook 200 can be simultaneously connected to the grounding end and the device end, respectively. Therefore, the present application sets that when the system is started, the actual distance between the grounding clamp 100 and the grounding hook 200 is greater than or equal to the set error prevention distance, the alarm mechanism starts to alarm, reminding the operator to check whether the grounding clamp 100 is connected to the grounding end, and then the operator decides whether to connect or remove the grounding hook 200 according to the check result. The present application sets the error prevention distance, and alarms when the actual distance between the grounding clamp 100 and the grounding hook 200 is greater than the error prevention distance, reminding the operator to check the connection of the grounding clamp 100, which can prevent the operator from making a mistake and causing danger to a certain extent.

[0114] Optionally, D 防误 It can be set to 1%-99% of the distance between the grounding end and the device end. Specifically, the error prevention distance D 防误 It can be 1%, 10%, 20%, 25%, 50%, 60%, 99%, etc. of the distance between the grounding end and the device end, and the present application embodiment does not limit this. For example, the distance between the grounding end and the device end is 10m, and D 防误 It can be set to 3m.

[0115] Optionally, the alarm mechanism can alarm and prompt through sound, light, color, text, etc. that can be recognized by the operator.

[0116] When the operator checks that the grounding clamp 100 has been connected to the grounding end, or the operator reconnects the grounding clamp 100 after finding that the grounding clamp 100 is not connected to the grounding end, the alarm can be manually released by the operator or the system control alarm release.

[0117] In the above scheme, when the actual distance D between the grounding clamp 100 and the grounding hook 200 is greater than or equal to the set anti-misoperation distance, the alarm mechanism releases the alarm. 实际 ≥D 防误 , and the grounding clamp 100 is connected to the grounding end, the alarm mechanism releases the alarm.

[0118] In the above scheme, when the actual distance D between the grounding clamp 100 and the grounding hook 200 is greater than or equal to the set anti-misoperation distance, the alarm mechanism releases the alarm.

[0119] In a possible implementation, the alarm judgment unit is configured to: if it is detected that D 实际 <D 防误 , and the grounding clamp 100 is not connected to the grounding end, the alarm mechanism starts the alarm.

[0120] In the above implementation process, when the actual distance D between the grounding clamp 100 and the grounding hook 200 is less than the anti-misoperation distance, but the grounding clamp 100 is not installed with the grounding end, the grounding hook 200 and the grounding clamp 100 may approach the equipment end at the same time, and the two are kept within the anti-misoperation distance. In this case, the operator may incorrectly connect the grounding hook 200 and the grounding end when the grounding clamp 100 is not connected to the grounding end. Therefore, the application is provided. When the actual distance D between the grounding clamp 100 and the grounding hook 200 is less than the anti-misoperation distance, but the grounding clamp 100 is not installed with the grounding end, the alarm starts the alarm to remind the operator to check whether the grounding clamp 100 is connected to the grounding end, and to decide whether to connect or remove the grounding hook 200 according to the result.

[0121] In a possible implementation, the alarm judgment unit is configured to: if it is detected that D 实际 <D 防误 , and the grounding clamp 100 is connected to the grounding end, the alarm mechanism releases the alarm.

[0122] In the above implementation process, when the actual distance D between the grounding clamp 100 and the grounding hook 200 is less than the anti-misoperation distance, but the grounding clamp 100 is not installed with the grounding end, the grounding hook 200 and the grounding clamp 100 may approach the equipment end at the same time, and the two are kept within the anti-misoperation distance. In this case, the operator may incorrectly connect the grounding hook 200 and the grounding end when the grounding clamp 100 is not connected to the grounding end. Therefore, the application is provided. When the actual distance D between the grounding clamp 100 and the grounding hook 200 is less than the anti-misoperation distance, but the grounding clamp 100 is not installed with the grounding end, the alarm starts the alarm to remind the operator to check whether the grounding clamp 100 is connected to the grounding end, and to decide whether to connect or remove the grounding hook 200 according to the result.

[0123] In a fourth aspect, the present application also provides a computer readable storage medium, which stores instructions, and the instructions are executed by a processor to perform the anti-misoperation method of the grounding set.

[0124] The processor can include one or more processing cores. The processor connects various parts within the server through various interfaces and lines, and performs various functions of the server and processes data by running or executing instructions, programs, code sets or instruction sets stored in the memory, and calling data stored in the memory. Optionally, the processor can be implemented in at least one of a hardware form of a digital signal processing (DSP), a field-programmable gate array (FPGA), and a programmable logic array (PLA). The processor can be integrated with a combination of one or more of a central processing unit (CPU), a graphics processing unit (GPU), and a modem. Among them, the CPU mainly processes operating systems, user interface graphs and application programs, etc.; the GPU is responsible for rendering and drawing the content required to be displayed on the display screen; and the modem is used for processing wireless communication. It can be understood that the above-mentioned modem can also not be integrated into the processor, but be realized by a separate chip.
