Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of high-voltage tower maintenance, in particular to a method and system for preventing mistaken entry into a live area of a tower, a storage medium, and a program product. BACKGROUND

[0002] As a key infrastructure in the transmission stage of the power system, a high-voltage tower bears the important task of long-distance and large-capacity power transmission. Its operating state is directly related to the safety and stability of the entire power grid and the reliability of power supply. Therefore, the regular maintenance and repair of the high-voltage tower have become a key link to ensure the safe operation of the power grid.

[0003] At present, in the traditional high-voltage tower maintenance process, manual electric verification operation and setting of maintenance signs are usually used to determine whether the tower work site is live. However, this operation method has obvious limitations: on the one hand, the electric verification operation is tedious and inefficient, and is prone to misjudgment due to human negligence; on the other hand, since the maintenance sign mainly prompts the maintenance personnel whether they can enter the specified cross arm through visual cues, it cannot enforce these provisions. In the case of complex working environment, the maintenance personnel may ignore the information on the maintenance sign, thereby mistakenly entering the live area of the tower, and further causing electric shock, electric arc injury, and other safety accidents. SUMMARY

[0004] The purpose of the embodiments of the present application is to provide a method and system for preventing mistaken entry into a live area of a tower, a storage medium, and a program product, to solve the problem that in the related art, during tower maintenance, maintenance personnel may mistakenly enter a live cross arm of the tower, thereby causing a safety accident.

[0005] The embodiments of the present application provide a method for preventing mistaken entry into a live area of a tower, which is applied to behavior management before maintenance of a live area of a tower. The tower includes a plurality of cross arms, and each cross arm is provided with a corresponding safety fence and a corresponding electric verification device. The method comprises the following steps: a computer key obtains operation task information, which is used to indicate that a maintenance personnel enters a target work cross arm, and the operation task information includes identification information of the target work cross arm; for an electric verification device on any cross arm, if the computer key supplies power to the electric verification device, the electric verification device verifies the cross arm where the electric verification device is located in the case of being powered on, and feeds back electric verification information in the case that the cross arm where the electric verification device is located is not live; the computer key obtains code chip information from the safety fence on the cross arm where the electric verification device is located in the case that the computer key receives the electric verification information sent by the electric verification device, and determines whether the identification information in the operation task information matches the code chip information; and the computer key unlocks the safety fence on the cross arm where the electric verification device is located in the case that the identification information matches the code chip information, so that the maintenance personnel can reach the end of the target work cross arm through the unlocked safety fence. wherein, in the case that the identification information does not match the chip information, the cross arm where the electricity testing device is located is a cross arm other than the target working cross arm; correspondingly, the safety fence on the cross arm where the electricity testing device is located remains in the locked state in the case that the identification information does not match the chip information.

[0006] In the above implementation manner, the electricity testing device is arranged to test the cross arm, and meanwhile, the computer key is limited to obtain the chip information from the safety fence on the cross arm where the electricity testing device is located only in the case that the electricity testing device sends electricity testing information representing that the cross arm is not electrified, and the safety fence is limited to be unlocked only in the case that the chip information of the safety fence matches the identification information in the operation task information. Therefore, before the maintenance personnel obtain the operation task information by using the computer key and enter the target working cross arm for maintenance, the maintenance personnel must first perform the electricity testing operation on the target working cross arm, and the safety fence can be unlocked only in the case that the target working cross arm is not electrified, so that the maintenance personnel can work at the end of the target working cross arm. The electricity testing operation and the authorized unlocking are used for double protection, so that the maintenance personnel can work at the end of the target working cross arm which is not electrified, the possibility of the maintenance personnel entering the end of the cross arm other than the target working cross arm is reduced, and the safety and reliability of the high-voltage electrification anti-misentry control are improved.

[0007] Further, the electricity testing device includes a high-voltage electrification indicator and a sensor, the high-voltage electrification indicator is electrically connected to the sensor, the sensor is arranged on the cross arm of the iron tower, and if the computer key supplies power to the electricity testing device, the computer key supplies power to the high-voltage electrification indicator of the electricity testing device; the sensor of the electricity testing device tests the cross arm where the sensor is located and sends the detected electrical signal information to the high-voltage electrification indicator of the electricity testing device in the case that the high-voltage electrification indicator of the electricity testing device is powered on, and the high-voltage electrification indicator of the electricity testing device feeds back the electricity testing information in the case that the electrical signal information represents that the cross arm is not electrified.

[0008] In the above implementation manner, since the maintenance personnel must carry the computer key to open the safety fence when the maintenance personnel performs the maintenance on the iron tower, the computer key is used to supply power to the high-voltage electrification indicator, so that the maintenance personnel only need to carry the computer key to complete the operation of opening the safety fence and supplying power to the high-voltage electrification indicator, and the trouble of the maintenance personnel carrying multiple tools is reduced. Moreover, compared with the scheme of directly arranging the power supply in the high-voltage electrification indicator and replacing the power supply when the power supply is exhausted, the high-altitude operation caused by the replacement of the power supply is avoided, and the workload and the safety risk are reduced.

[0012] In the above implementation, the computer key unlocks the mechanical lock, so that the protective door fence can be opened. In this way, the maintenance personnel can only open the protective door fence and reach the end of the cross arm when the mechanical lock is unlocked. At the same time, since the mechanical lock can only be unlocked when the cross arm is not electrified and the code chip information in the mechanical lock matches the identification information in the computer key, the possibility of the maintenance personnel entering the electrified cross arm for work is reduced, and the safety and reliability of the high-voltage electrified anti-misentry control are improved.

[0013] Further, after the computer key unlocks the safety fence on the cross arm where the electricity testing device is located, the computer key controls the safety fence on the cross arm where the electricity testing device is located to be locked when the maintenance personnel exits the target work cross arm.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0030] Embodiment one: In combination with Figure 1As shown, the application provides a system 100 for preventing mistaken entry into a live tower area, which is applied to behavior control before maintenance of the live tower area. The tower includes multiple cross arms. The system includes multiple safety fences 10, multiple electricity checking devices 20 and a computer key 30.

[0031] The computer key 30 is used to obtain operation task information. The operation task information is used to indicate that the maintenance personnel enters the target working cross arm. The operation task information can include identification information of the target working cross arm. The computer key 30 can display the operation task information. In this way, the maintenance personnel can determine the target working cross arm through the operation task information displayed by the computer key.

[0032] Optionally, the operation task information can also include operation process information. The operation process information is used to indicate a working process before the maintenance personnel enters the target working cross arm. For example, the working process can include obtaining maintenance tools at a preset location, performing electricity checking operation on the target working cross arm, and unlocking the safety fence of the target working cross arm.

[0033] Optionally, the computer key 30 can be specifically used to obtain the operation task information from a work ticket system. The work ticket system is deployed on a mobile terminal. The work ticket system is used to obtain the operation task information from a work ticket in a case where the work ticket is received by the mobile terminal. The mobile terminal is used to upload the work ticket corresponding to the work ticket input operation to the work ticket system in a case where the work ticket input operation is received.

[0034] The operation task information can include identification information or position information of the target working cross arm. For example, the computer key can display the identification information or position information of the target working cross arm. In this way, the maintenance personnel can know the identification information or position information of the target working cross arm, so as to carry the computer key to climb the tower and reach the entrance position of the target working cross arm.

[0035] In a case where the maintenance personnel knows the identification information or position information of the target working cross arm, the computer key can be used to power the electricity checking device of the target working cross arm, so that the electricity checking device of the target working cross arm checks the electricity of the target working cross arm.

[0036] Optionally, in combination with Figure 2 As shown in the structural schematic diagram of the tower, the tower can include multiple cross arms 40. Each cross arm 40 can be provided with a corresponding safety fence 10 and an electricity checking device 20. Therefore, it is also possible that the maintenance personnel reaches the entrance position of the cross arm other than the target working cross arm after climbing the tower. Similarly, the computer key can be used to power each electricity checking device. Similarly, each electricity checking device can check the electricity of the cross arm where the electricity checking device is located in a case where the electricity checking device is powered.

[0037] The electrification detection device 20 is configured to detect electrification of the cross arm 40 where the electrification detection device 20 is located in the case of power-on. In addition, the electrification detection device 20 can also be configured to feed back electrification information to the computer key 30 in the case that the cross arm 40 where the electrification detection device 20 is located is not electrified, and the electrification information includes identification information of the electrification detection device 20. The identification information of the electrification detection device 20 can be the same as the identification information of the cross arm where the electrification detection device 20 is located, and of course, the identification information of the electrification detection device 20 can also be different from the identification information of the cross arm 40 where the electrification detection device 20 is located.

[0038] Optionally, the electrification detection device 20 can include a high-voltage electrification indicator 21 and a sensor 22, the high-voltage electrification indicator 21 is electrically connected with the sensor 22, and the sensor 22 is arranged on the cross arm 40 of the tower.

[0039] In detail, the computer key 30 can be used to power the high-voltage electrification indicator 21, the sensor 22 detects electrification of the cross arm 40 where the sensor 22 is located in the case of power-on of the high-voltage electrification indicator 21, and sends the detected electrical signal information to the high-voltage electrification indicator 21, and the high-voltage electrification indicator 21 feeds back electrification information to the computer key 30 in the case that the electrical signal information represents that the cross arm 40 is not electrified. The electrification information can include identification information of the high-voltage electrification indicator 21, and the identification information of the high-voltage electrification indicator 21 can be the same as the identification information of the cross arm 40 where the sensor 22 connected with the high-voltage electrification indicator 21 is located.

[0040] For any electrification detection device 20 on a cross arm, if the computer key 30 powers the electrification detection device 20, the electrification detection device 20 detects electrification of the cross arm where the electrification detection device 20 is located in the case of power-on, and feeds back electrification information in the case that the cross arm where the electrification detection device 20 is located is not electrified; Optionally, the computer key 30 can also be used to acquire code chip information from the safety fence 10 on the cross arm where the electrification detection device 20 is located in the case that the computer key 30 receives the electrification information fed back by the electrification detection device 20, and determine whether the identification information in the operation task information matches the code chip information; and in the case that the identification information in the operation task information matches the code chip information, unlock the safety fence 10 on the cross arm where the electrification detection device 20 is located, so that the maintenance personnel can reach the end of the target working cross arm 40 through the unlocked safety fence 10. In the case that the identification information in the operation task information does not match the code chip information, it represents that the cross arm where the electrification detection device 20 is located is a cross arm other than the target working cross arm. At this time, the safety fence on the cross arm where the electrification detection device is located can be kept in a locked state.

[0041] For example, the computer key 30 can display the live-line information sent by the live-line device when receiving the live-line information. In this way, the maintenance personnel can know that the computer key has obtained the live-line information through the live-line information displayed by the computer key, so that the computer key 30 can obtain the chip information from the safety fence 10 on the cross arm where the live-line device 20 is located. In other words, the chip information is obtained from the safety fence on the cross arm where the live-line device sending the live-line information is located. And determine whether the identification information in the operation task information matches the chip information. In the case where the identification information in the operation task information matches the chip information, the safety fence 10 is unlocked to enable the maintenance personnel to reach the end of the cross arm 40 through the unlocked safety fence 10. In other words, in the case where the identification information in the operation task information matches the chip information, the cross arm where the live-line device is located is the target working cross arm. The safety fence on the cross arm where the live-line device is located is unlocked, that is, the safety fence on the target working cross arm is unlocked, so that the maintenance personnel can reach the end of the target working cross arm through the unlocked safety fence to work.

[0042] And in the case where the identification information in the operation task information does not match the chip information, the cross arm where the live-line device is located is a cross arm other than the target working cross arm, and at this time the locking state of the safety fence on the cross arm where the live-line device is located can be maintained, so that the maintenance personnel cannot reach the end of the cross arm other than the target working cross arm.

[0043] Optionally, after the computer key 30 unlocks the safety fence 10 on the cross arm where the live-line device is located, the computer key 30 further controls the safety fence 10 on the cross arm where the live-line device is located to be locked when the maintenance personnel exits the cross arm 40 where the live-line device is located.

In the case where the identification information in the operation task information matches the chip information, the mechanical lock 12 is unlocked to enable the protective door fence 11 to open or close. Correspondingly, in the case where the identification information in the live-line information does not match the chip information, the mechanical lock 12 is not unlocked, that is, the closing state of the mechanical lock 12 can be maintained.

[0058] Correspondingly, the computer key 30 controls the safety fence 10 to be locked, including that in the case that the protective door bar 11 is closed, the computer key 30 controls the mechanical lock 12 to be locked.

[0059] Correspondingly, the computer key 30 controls the safety fence 10 to be locked, including that in the case that the protective door bar 11 is closed, the computer key 30 controls the mechanical lock 12 to be locked.For example, when the guard gate 11 is open, the position of the guard gate 11 on the cross arm 40 can be as follows: Figure 8 When the guard gate 11 is closed, the position of the guard gate 11 on the cross arm 40 can be as shown. Figure 9 shown.

[0060] The system provided by the present application prevents accidental entry into the live area of ​​the tower by setting up an electric test device to perform an electric test operation on the crossarm, and at the same time limits the computer key to only obtain code information from the safety fence on the crossarm where the electric test device is located when it receives electric test information sent by the electric test device indicating that it is not energized, and limits the safety fence to be unlocked only when its own code information matches the identification information in the operation task information. Therefore, before maintenance personnel obtain the operation task information through the computer key and enter the target working crossarm for maintenance, they must first perform an electric test operation on the target working crossarm to ensure that the target working crossarm is not energized before they can unlock the safety fence and enter the end of the target working crossarm to work. The dual protection of electric test operation and authorized unlocking ensures that maintenance personnel can work at the end of the target working crossarm that is not energized, reduces the possibility of maintenance personnel accidentally entering the end of a crossarm other than the target working crossarm, and improves the safety and reliability of high-voltage live anti-accidental entry control.

[0061] Example 2 Combine Figure 10 As shown, the present application provides a method for preventing accidental entry into the live area of ​​a tower, which is applied to behavior control before maintenance in the live area of ​​the tower. A safety fence and an electrical testing device are provided on the cross arm of the tower. The method includes: Step S101: The computer key obtains operation task information, which is used to instruct maintenance personnel to enter a target working crossarm. The operation task information includes identification information of the target working crossarm.

[0062] Optionally, the computer key obtains operation task information from the work ticket system; the work ticket system is used to obtain operation task information from the work ticket when receiving the work ticket sent by the mobile terminal, and send the operation task information to the computer key; the mobile terminal is used to upload the work ticket corresponding to the work ticket input operation to the work ticket system when receiving the work ticket input operation.

[0063] For example, the maintenance personnel can log in the work order system through the mobile terminal, and then perform a work order input operation on the mobile terminal. The mobile terminal can obtain work order information from the work order input operation upon receiving the work order input operation. The mobile terminal can upload the work order to the work order system upon obtaining the work order information. The work order system can obtain operation task information from the work order upon obtaining the work order, and send the operation task information to the computer key. In this way, the computer key can obtain the operation task information.

[0064] In step S102, for any live line detection device on a cross arm, if the computer key supplies power to the live line detection device, the live line detection device performs live line detection on the cross arm where the live line detection device is located, and feeds back live line detection information if the cross arm where the live line detection device is located is not live, the live line detection information including identification information.

[0065] Alternatively, the live line detection device includes a high-voltage live line indicator and a sensor, the high-voltage live line indicator being electrically connected to the sensor, the sensor being arranged on the cross arm of the tower, and the computer key supplies power to the live line detection device, including: the computer key supplies power to the high-voltage live line indicator of the live line detection device; the sensor of the live line detection device performs live line detection on the cross arm where the live line detection device is located and sends the detected electrical signal information to the high-voltage live line indicator of the live line detection device if the high-voltage live line indicator of the live line detection device is powered on, and the high-voltage live line indicator of the live line detection device feeds back live line detection information if the electrical signal information indicates that the cross arm is not live.

[0066] In step S103, the computer key obtains code chip information from the safety fence on the cross arm where the live line detection device is located upon receiving the live line detection information sent by the live line detection device, and determines whether the identification information in the operation task information matches the code chip information.

[0067] In step S104, the computer key unlocks the safety fence on the cross arm where the live line detection device is located if the identification information in the operation task information matches the code chip information, so that the maintenance personnel can reach the end of the target work cross arm through the unlocked safety fence.

[0068] In the case where the identification information in the operation task information does not match the code chip information, the cross arm where the live line detection device is located is a cross arm other than the target work cross arm; correspondingly, the safety fence on the cross arm where the live line detection device is located remains in a locked state if the identification information in the operation task information does not match the code chip information.

[0069] Alternatively, the safety fence includes a protective door fence and a mechanical lock, the protective door fence being arranged on the cross arm, and the mechanical lock being installed on the protective door fence and used to control opening and closing of the protective door fence; the computer key unlocking the safety fence includes: the computer key unlocking the mechanical lock to enable the protective door fence to be opened.

[0070] The method provided by the present application for preventing accidental entry into the energized area of ​​a tower is to perform an electrical test on the crossarm by setting an electrical test device, and at the same time, to limit the computer key to obtaining code chip information from the safety fence on the crossarm where the electrical test device is located only when it receives electrical test information sent by the electrical test device indicating that it is not energized, and to limit the safety fence to be unlocked only when its own code chip information matches the identification information in the operation task information. Therefore, before maintenance personnel obtain the operation task information through the computer key and enter the target working crossarm for maintenance, they must first perform an electrical test on the target working crossarm to ensure that the target working crossarm is not energized before they can unlock the safety fence and enter the end of the target working crossarm to work. The dual protection of electrical test operation and authorized unlocking ensures that maintenance personnel can work at the end of the target working crossarm that is not energized, reduces the possibility of maintenance personnel accidentally entering the end of other crossarms, and improves the safety and reliability of high-voltage live-line prevention and control.

[0071] It should be understood that, for the sake of brevity, some of the contents described in the first embodiment will not be repeated in this embodiment.

[0072] Example 3 Combine Figure 11 As shown, this embodiment describes in detail the aforementioned method for preventing accidental entry into the live area of ​​the tower with a specific embodiment.

[0073] In the first step, maintenance personnel log in to the work ticket system via a mobile terminal. They then enter and submit a work ticket, which includes the work ticket number, task name, and task details. Once the work ticket is received, the work ticket system extracts the task information from the ticket and sends it to the computer key. This allows the computer key to obtain the task information.

[0074] For example, a maintenance worker can input a work ticket on a mobile terminal and submit Work Ticket A. Work Ticket A may include the work ticket number "001," the task name "High-voltage tower inspection," and the task content "Maintain crossarm No. 5 of Tower No. 3." Upon receiving Work Ticket A, the work ticket system may generate operational task information for Work Ticket A. The operational task information may include the work location of Work Ticket A, "Crossarm No. 5 of Tower No. 3," the identification information of the target crossarm, "No. 5," and operational process information. The operational process information may include a workflow, which, from front to back, is as follows: obtain maintenance tools at a preset location; climb Tower No. 3 and use a computer key to power the high-voltage live indicator corresponding to crossarm No. 5 of Tower No. 3 to perform an electrical test on crossarm No. 5 of Tower No. 3; and unlock the safety fence of crossarm No. 5 when crossarm No. 5 is de-energized.

[0075] Secondly, the maintenance personnel can obtain the working position from the operation task information in the computer key, i.e. the target working cross arm. Then the maintenance personnel can climb to the tower working circuit. If the maintenance personnel climbs the circuit correctly, the maintenance personnel can use the computer key to insert the high-voltage live indicator on the target working cross arm to power the high-voltage live indicator on the target working cross arm. However, if the maintenance personnel climbs the circuit incorrectly, the maintenance personnel can insert the computer key into the high-voltage live indicator on the cross arm other than the target working cross arm to power the high-voltage live indicator on the cross arm other than the target working cross arm. However, in the case of powering any high-voltage live indicator, the sensor connected with the high-voltage live indicator can detect the electricity of the cross arm where the sensor is located and send the detected electrical signal information to the high-voltage live indicator. In the case that the electrical signal information represents that the cross arm is not electrified, the high-voltage live indicator feeds back the electricity detection information to the computer key.

[0076] Thirdly, in the case that the computer key receives the electricity detection information sent by the high-voltage live indicator, the computer key can obtain the code chip information from the handle lock of the cross arm where the high-voltage live indicator is located and determine whether the identification information in the operation task information matches the code chip information. In the case that the identification information in the operation task information matches the code chip information, the handle lock is unlocked. In the case that the identification information in the operation task information does not match the code chip information, the handle lock remains in the locked state.

[0077] Fourthly, in the case that the handle lock is unlocked, the maintenance personnel can rotate the handle lock so that the bolt connected with the handle lock can exit the bolt hole along the axial direction of the bolt hole. Then the maintenance personnel can push the door bar so that the door bar rotates around the axis of the door bar fixing rod, thereby opening the door bar. In this way, the maintenance personnel can enter the end of the target working cross arm through the door bar for maintenance.

[0078] Fifthly, after the maintenance personnel completes the work, the maintenance personnel can close the door bar on the target working cross arm, then rotate the handle lock so that the bolt is inserted into the bolt hole, and then use the computer key to lock the handle lock.

[0079] Sixthly, the maintenance personnel can perform the operation information feedback operation on the mobile terminal to end the corresponding work ticket task.
