Description

Technical Field

[0001] The present invention relates to the field of electric power systems, in particular to the field of power transmission and distribution line maintenance construction operations in electric power systems, and specifically to a monitoring method and a safety tool system for electric power construction operations. Background Art

[0002] In the field of power transmission and distribution line operations, the main method of power construction operations is to install grounding equipment (such as grounding short-circuit devices and grounding switches) on the power transmission and distribution line equipment that is shut down for maintenance. When high-altitude operations are required, safety belts are also used to ensure the personal safety of operators. If the power transmission and distribution line equipment that is shut down for maintenance suddenly receives power, the grounding equipment can cause a phase-to-phase short circuit and introduce the short-circuit current into the ground, thereby protecting the operators from electric shock. There is induced electricity in the power transmission and distribution line equipment that is shut down for maintenance. By installing a grounding short-circuit device or closing the grounding switch, the induced electricity on the power transmission and distribution line equipment that is shut down for maintenance can be shielded to prevent operators from being injured by induced electricity. Power transmission and distribution line operations often require operators to climb poles and towers to carry out high-altitude operations. Safety belts need to be used throughout the high-altitude operations to prevent the risk of operators falling from heights.

[0003] Therefore, when working on power transmission and distribution lines, workers must correctly install grounding equipment and other measures before touching maintenance equipment to prevent personal electric shock and casualties; they must correctly wear safety belts during the entire process of climbing towers to prevent high-altitude falls and casualties. However, in actual on-site work, there are still situations where the grounding short-circuit device is not installed or removed in a standardized manner, and safety belts are not used properly during high-altitude work, which can cause personal injury and death accidents. Therefore, the most important control task for strengthening the safety control of the transmission and distribution line operation site is to control the operators to use safety tools such as grounding short-circuit devices, smart safety belts, and grounding knife switches in a standardized manner. For example, the grounding short-circuit devices are not installed comprehensively or the grounding knife switches are not closed properly, and they are not installed on all sides of the power outage maintenance equipment that may receive power (it can also be understood as failing to install grounding short-circuit devices or close grounding knife switches at all the grounding positions set); operators install grounding short-circuit devices with power on; operators operate beyond the protection range of the grounding equipment and mistakenly climb live poles and towers; high-altitude operations lose protection; grounding short-circuit devices are not completely removed, grounding short-circuit devices are left on power equipment, and grounding knife switches are improperly closed; transmission and distribution line operations are carried out without an operation plan; the person in charge of the work leaves the operation site, etc. The above serious violations are very likely to cause malignant accidents such as electric shock, falling from height, and power transmission with grounding short-circuit devices, causing great harm to personal and power grid safety.

[0004] In order to standardize the use of grounding short-circuit devices, smart safety belts, etc., a variety of monitoring methods have appeared on the market. They mainly use the sensors installed on the grounding short-circuit devices themselves to sense the status of the grounding short-circuit devices. Once the grounding short-circuit devices are installed in an unqualified order or are not installed firmly, they can be discovered in time and reminded to rectify the problems of the operators. There are also a variety of monitoring methods for smart safety belts, which can prevent the removal of smart safety belts during high-altitude operations, and also play a positive role in improving the compliance of grounding short-circuit devices and smart safety belts. However, the current monitoring methods generally have monitoring limitations. They are limited to the information data of one safety tool, and fail to make full use of the data sent by multiple safety tools for linkage analysis. They also fail to make full use of multiple power grid databases for multi-data linkage analysis, and fail to effectively monitor the safety risks that are the most harmful to the personal and power grid safety of operators and the most serious impact. It is precisely because of this that the risks of accidents such as electric shock, falling from height, and power transmission with grounding short-circuit devices in power construction operations have not been effectively controlled, and personal and power grid accidents caused by them still occur from time to time.

[0005] In summary, how to conduct timely and accurate monitoring of construction work on power transmission and distribution lines and reduce safety risks caused by non-compliant operations are issues that need to be considered in solving the above problems or risks. Summary of the invention

[0016] Furthermore, when the identity information of the smart work card is the person in charge of the work, after the first preset time ends, it is detected that the positioning position of the smart work card in the working state does not belong to the safe operating area of ​​the power transmission and distribution line associated with the smart work card, and an alarm message is issued that the person in charge of the work is not at the work site.

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] As mentioned in the background technology, "During the power construction process, serious violations cannot be monitored in a timely and accurate manner with the existing monitoring methods. It is precisely because of this that the risks of accidents such as electric shock, falling from heights, and power transmission with grounded short-circuit devices caused by power construction operations have not been effectively controlled, and personal and power grid accidents caused by this still occur from time to time." The inventors of this application conducted a detailed analysis of the construction operations of power transmission and distribution lines and found that in the power transmission and distribution line operations, the main reasons why the risks have not been effectively controlled are the design difficulties in two aspects: monitoring reference information and monitoring logic design. The monitoring method adopted by the present invention conducts comprehensive monitoring through the information sent by multiple smart tools and combines various information of power grid data to form a comprehensive monitoring logic to detect the non-compliant use of smart tools, thereby reducing the construction operation risks in power transmission and distribution line operations.

[0028] In order to better explain the present invention, the monitoring system is first explained.

[0029] like Figure 1 As shown, a safety tool system includes a server (also referred to as a background subsystem in this article), multiple grounding short-circuit devices, multiple smart work cards, and multiple smart safety belts. The background subsystem can be connected to the smart safety belt, the grounding short-circuit device, and the smart work card respectively by wireless communication. The detection data sent by the smart safety belt and / or the grounding short-circuit device and / or the smart work card to the background subsystem during the construction process, and the background subsystem combines the information in the power grid data such as planning information, ledger information, and operation information for comprehensive monitoring. The grounding short-circuit device, smart work card, and smart safety belt are first introduced below.

[0030] like Figure 2 As shown, the ground short-circuit device mainly includes components such as a single-chip microcomputer, a communication unit, a positioning device, a pressing sensor, a hook sensor group, and an audible and visual alarm. The pressing sensor is arranged at the ground end of the ground short-circuit device to generate a ground end connection signal, and the hook sensor group is arranged at the conductor end of the ground short-circuit device to generate a conductor end connection signal. The number of sensors in the hook sensor group is set according to specific needs. For example, when the three-phase four-wire system corresponding to the power construction is used, the hook sensor group uses four pressure sensors to ensure that each transmission line is reliably connected to the ground. The communication unit can be a wireless transmission unit such as 4G, LoRa, and NB.

[0031] like Figure 3 As shown, the smart seat belt at least includes: a controller and other devices, and the other devices include multiple pressure sensors, multiple air pressure sensors, a communication unit, a positioning sensor (also called a positioning device), an audible and visual alarm, etc. The controller is connected to multiple pressure sensors, multiple air pressure sensors, a communication unit, and a positioning sensor. Among them, the multiple pressure sensors include an N1 pressure sensor and an N2 pressure sensor; the N1 pressure sensor is set at the connection of the safety belt and is used to detect the reliable signal of the waist belt connection of the safety belt; the N2 pressure sensor is set on the self-locking device hanging ring of the detection safety belt and is used to detect the reliable connection signal between the self-locking device hanging ring of the smart seat belt and the self-locking device. The multiple air pressure sensors include an air pressure sensor 1 and an air pressure sensor 2. The air pressure value sensor 1 is set at the backup rope hook and is used to detect the air pressure value at the backup rope hook of the safety belt. The air pressure sensor 2 is set below the backup rope hook of the safety belt (preferably set on the belt) and is used for the air pressure value below the backup rope hook of the safety belt. The fixing method of multiple pressure sensors, multiple air pressure sensors, communication units, and positioning sensors is adapted according to the purpose of the invention, and will not be repeated here. In terms of hardware design, the controller uses a wired connection to connect each sensor, which can avoid the high power consumption of wireless communication between the hardware sensor and the controller (such as a single-chip microcomputer), and improve the continuous operation time of the safety belt. It should be noted that the smart work card includes a single-chip microcomputer, and a vibration start switch, a wireless communication unit, an audible and visual alarm, a positioning unit and a memory connected to the single-chip microcomputer. The smart work card can obtain the vibration start information of the smart work card (triggered by the vibration start switch) through the single-chip microcomputer; obtain the positioning position through the positioning unit, and determine the status information of the smart work card according to the start information of the smart work card (when the vibration start information triggered by the vibration start switch is detected, it is determined that the smart work card is in a working state), and send the positioning position corresponding to the status information and the stored identity information to the background subsystem. The hardware selection of the smart work card is adapted according to the purpose of the invention of the present invention, and will not be repeated here. The selection of the grounding short-circuit device, the background subsystem and other specific hardware parts of the intelligent safety belt in the above-mentioned safety tool system (such as the positioning unit or positioning device, and the communication unit that connects the background subsystem to the intelligent safety belt, the grounding short-circuit device, the power grid one-picture system, the operation planning system, the work ticket system, the power monitoring system, the distribution automation system, the dispatching command system and other equipment) is based on the understanding of those skilled in the art and will not be repeated here.

[0032] According to a first aspect of the present invention, a monitoring method for electric power construction work is provided, such as Figure 4As shown, the monitoring method mainly includes two main processes: obtaining the information that needs to be monitored and using the monitoring logic to monitor the obtained information. Specifically, the monitoring method includes: S1. Receiving the detection data of the smart tool during use, the detection data including status information and positioning information; wherein, the power transmission and distribution line associated with the smart tool is determined by using the pre-configured ledger information in the power grid data and the positioning information of the smart tool under the status information, and the power transmission and distribution line associated with the smart tool is used as the power transmission and distribution line installed by the smart tool; S2. According to the power transmission and distribution line installed by the smart tool, the plan information corresponding to the power transmission and distribution line is obtained, and when it is determined that the plan information corresponding to the power transmission and distribution line is an unplanned operation, an unplanned operation alarm information of the power transmission and distribution line is issued; and according to the power transmission and distribution line installed by the smart tool, the current operation information of the power transmission and distribution line is obtained, and when it is determined that the current operation information of the power transmission and distribution line is an energized state, Send out an alarm message that the power transmission and distribution line is energized; S3. Repeat S1-S2 within the preset installation time until the preset installation time is over, determine the actual number of intelligent tools associated with each power transmission and distribution line, and obtain the number of grounding switches in the closed state on each power transmission and distribution line and the planned associated number in the planned information of each power transmission and distribution line; use the actual number of intelligent tools associated with the power transmission and distribution line, the number of grounding switches in the closed state and the planned associated number in the planned information to send out corresponding alarm messages; wherein, when the planned associated number in the planned information of the power transmission and distribution line is greater than the actual number, send out an alarm message that the grounding short-circuit device is not fully installed; wherein, the actual number is the sum of the actual number of intelligent tools associated with the power transmission and distribution line and the number of grounding switches in the closed state. wherein, when the intelligent tool is a grounding short-circuit device, the alarm message that the power transmission and distribution line is energized issued in the monitoring method is specifically a "line is energized, grounding is prohibited" alarm signal, which can be prompted in three ways. First, a pop-up window alarm message is displayed on the human-computer interaction interface of the background subsystem to remind the background system security monitoring personnel; second, the background subsystem automatically sends a text message to the person in charge of the work; third, the background subsystem automatically sends it to the grounding short-circuit device that provides the positioning information, and the grounding short-circuit device sends an audible and visual alarm to prevent and control the risk of operators installing the grounding short-circuit device with power on. When the intelligent tool is an intelligent safety belt, the alarm message of the power transmission and distribution line being energized issued in the monitoring method is specifically the alarm message of "the line is energized, climbing the pole tower is prohibited", which prevents and controls the risk of operators operating beyond the protection range of the grounding short-circuit device and mistakenly climbing the energized pole tower. When the intelligent tool is an intelligent work card, the alarm message of the power transmission and distribution line being energized issued in the monitoring method is specifically the prompt message of "the line is energized", which reminds the ground operators that the power transmission and distribution line where they are located is energized and they should pay attention to the safety of the construction work. When the intelligent tool is an intelligent safety belt or an intelligent work card, the three prompting methods are the same as those of the grounding short-circuit device, which will not be repeated here.

[0033] It should be noted that the power grid data (for example, planning information, account information and operation information) required in the monitoring method can be directly obtained from one or more of the following systems by calling each system information data interface: a power grid one-picture system, a work plan system, a work ticket system, a power monitoring system, a distribution automation system, and a dispatch command system. Among them, the account information can be obtained from the power grid one-picture system, and the account information includes the name of the transmission and distribution line, the tower number, the location information of the transmission and distribution line and the tower, the real-time status and location information of the grounding knife switch on the transmission and distribution line, and the grounding knife switch; the planning information can be obtained from the work plan system, the work ticket system and the dispatch command system, and the planning information includes the name of the transmission and distribution line, the tower number to be operated, the number of grounding short-circuit devices required for the transmission and distribution line, pre-power transmission information, etc.; the operation information is obtained from the power monitoring system and the distribution automation system, and the operation information includes whether the transmission and distribution line is energized, etc.; the specific method of the above acquisition is known to those skilled in the art, and will not be repeated here.

[0034] In an embodiment of the present invention, the pre-configured ledger information in the power grid data includes the transmission and distribution line, the pole tower number on the transmission and distribution line, and the positioning position corresponding to the pole tower number; the transmission and distribution line associated with the smart tool is determined in the following manner: in the pre-configured ledger information in the power grid data, the pole tower number within the preset positioning range is obtained; the preset positioning range is an area extended by a preset range (e.g., 10 meters) based on the positioning information of the smart tool in the initial state (e.g., geographic location coordinates, 35.0367° east longitude, 30.2608° latitude); the transmission and distribution line where the pole tower number in the pole tower number within the preset positioning range is closest to the positioning information of the smart tool in the initial state (so as to eliminate the interference of system information) is located is used as the transmission and distribution line associated with the smart tool. Associating the smart tool with the transmission and distribution line facilitates the subsequent monitoring and calls the detection information of the smart tool associated with the transmission and distribution line. When obtaining the status of the grounding switch on each transmission and distribution line, the location and real-time status of the grounding switch can be directly obtained from the ledger information. It should be noted that in the monitoring method, a variety of information (such as smart tools, power grid data, etc.) is integrated, and within the preset installation time, such as 30 minutes, a comprehensive inspection is carried out to determine whether the grounding equipment is installed, so as to improve the accuracy of monitoring of power construction operations.

[0035] According to one embodiment of the present invention, in S3, when the planned associated number in the planned information of the transmission and distribution line is greater than the actual number, S1-S2 are repeated until the planned associated number in the planned information of the transmission and distribution line is equal to the actual number. When the intelligent tool is an intelligent grounding and short-circuiting device, the sum of the actual number of grounding switches in the closed state on the transmission and distribution line and the actual number of grounding and short-circuiting devices installed is taken as the actual number of grounding devices on the transmission and distribution line. Furthermore, when the planned associated number in the planned information of the transmission and distribution line is equal to the actual number, the position information corresponding to the grounding switch in the closed state on the transmission and distribution line is obtained, and the safe operating area of ​​the transmission and distribution line is determined based on the intelligent grounding and short-circuiting device currently associated with the transmission and distribution line and the obtained position information corresponding to the grounding switch.

[0036] Preferably, the safe operation area of ​​the power transmission and distribution line is determined in the following manner: the position information corresponding to the currently associated intelligent grounding short-circuit device and the obtained grounding knife switch on the power transmission and distribution line is used as a reference position on the power transmission and distribution line; any two reference positions on the power transmission and distribution line are connected according to the pre-configured geographic wiring diagram direction to form a connecting line of the two reference positions; the preset range is expanded in the vertical direction of the connecting line of the two reference positions, and the expanded area is used as a safe operation sub-area of ​​the power transmission and distribution line; each safe operation sub-area is processed by union to obtain the safe operation area of ​​the power transmission and distribution line. Preferably, any two reference positions are two non-repeating reference positions. According to the pre-configured geographic wiring diagram direction, it can be understood that the power transmission and distribution line is known on a map data of the power grid, and the connection operation is performed according to the trajectory of the power transmission and distribution line, which can maximize the accuracy of the division of the safe operation area, and then the preset range (for example, 10 meters) is expanded to reduce the error caused by inaccurate positioning position information, thereby improving the accuracy of monitoring.

[0037] Further, in the monitoring method, the S1 comprises:

[0038] Receive detection data of the smart seat belt during use, the detection data including status information and positioning information; wherein, the power transmission and distribution line associated with the smart seat belt is determined by using the pre-configured ledger information in the power grid data and the positioning information of the smart seat belt under the status information; on this basis, the monitoring method further includes:

[0039] When the received operating state of the smart safety belt is the tower climbing state, the height working state or the tower lowering state, the safe operating area of ​​the power transmission and distribution line associated with the smart safety belt is obtained; when the safe operating area of ​​the power transmission and distribution line associated with the smart safety belt is not obtained, an alarm message is issued that the operator is operating beyond the protection range of the grounding and short-circuiting device and mistakenly climbing up the energized tower; when the safe operating area of ​​the power transmission and distribution line associated with the smart safety belt is obtained, the positioning position of the smart safety belt in the tower climbing state, the height working state or the tower lowering state and the safe operating area of ​​the power transmission and distribution line associated with the smart safety belt are used to issue corresponding alarm messages; among which, when the positioning position of the smart safety belt in the tower climbing state, the height working state or the tower lowering state belongs to the safe operating area of ​​the power transmission and distribution line associated with the smart safety belt, an alarm message that someone is operating at height of the tower climbing is issued; otherwise, an alarm message is issued that the operator is operating beyond the protection range of the grounding and short-circuiting device and mistakenly climbing up the energized tower.

[0040] Among them, when the background subsystem receives the intelligent safety belt's high-altitude operation loss protection alarm signal, it sends the intelligent safety belt's high-altitude operation loss protection alarm information to the display screen and the guardian's terminal.

[0041] It should be noted that when the operator wears a smart safety belt to enter the work site, if it is detected that the operator is in the safe working area of ​​the power transmission and distribution line or the safe working area of ​​the power transmission and distribution line associated with the smart safety belt is not obtained, the background subsystem will not issue an alarm prompt, and will issue a prompt message that someone is working at a high altitude on the tower. If it is detected that the smart safety belt worn by the operator is not in the safe working area of ​​the power transmission and distribution line, the background subsystem will issue an alarm pop-up window, prompting that the operator is working beyond the protection range of the grounding short-circuit device, and the operator is not allowed to start the work. This can prevent personnel from mistakenly entering areas outside the safe working area such as live intervals or mistakenly climbing live towers, improve the accuracy of the monitoring method, and avoid personal electric shock accidents. In addition, the automatic generation of the safe working area of ​​the transmission and distribution line can effectively improve the accuracy of monitoring on the one hand, realize no alarm for working within the grounding protection range, and create conditions for alarming beyond the grounding protection range, reducing the occurrence of false alarms and missed alarms. On the other hand, there is no need for personnel to manually mark the working area twice, which can improve the convenience of using this method.

[0042] Furthermore, the monitoring method further includes receiving detection data of the smart work card during use, wherein the detection data includes identity information, state information and positioning information; wherein the power transmission and distribution line associated with the smart work card is determined by using the pre-configured ledger information in the power grid data and the positioning information of the smart work card in the working state;

[0043] The monitoring method also includes: obtaining the safe operating area of ​​all current power transmission and distribution lines, and determining whether the positioning position of the smart work card in the working state is within the safe operating area of ​​the power transmission and distribution lines, wherein if the positioning position of the smart work card in the working state is within the safe operating area of ​​the power transmission and distribution lines associated with the smart work card, a reminder message of someone doing construction work is issued; if the positioning position of the smart work card in the working state is not within the safe operating area of ​​each power transmission and distribution line, a warning message that the operator is not in the working area is issued.

[0044] Preferably, when the identity information of the smart work card is the person in charge of the work, after the first preset time is over, it is detected that the location of the smart work card in the working state does not belong to the safe operation area of ​​the power transmission and distribution line associated with the smart work card, and an alarm message that the person in charge of the work is not at the work site is issued. The first preset time is preferably 1 hour, which can well monitor whether the person in charge of the work is at the power construction site and improve the safety of monitoring.

[0045] Preferably, when a reminder message of construction work is issued, after the second preset time, the identity information of the smart work card in the safe operation area of ​​the power transmission and distribution line is determined; according to the identity information of the smart work card in the safe operation area of ​​the power transmission and distribution line, the personnel allocation information in the plan information is obtained, and when the personnel allocation information in the obtained plan information is inconsistent with the pre-configured personnel allocation information, an unqualified work team member alarm message is issued. The backend subsystem queries the personnel allocation information in the power transmission and distribution line operation plan in the plan information in the power grid database, such as the identity information of the work team members and the number of work team members. The backend subsystem queries the number of work team members and member identity information entering the safe operation area of ​​the power transmission and distribution line through the identity information, status information and positioning location information sent by the received smart work card. If the number of work team members entering the safe operation area of ​​the power transmission and distribution line is insufficient or they are not work team members, or the safety qualifications of the work team members are unqualified, the backend subsystem issues an "unqualified work team members" alarm message. Among them, the second preset time is preferably 10 minutes. Within 10 minutes after the construction work reminder information is issued, the identity information of the smart work card in the safe operation area is detected, which can effectively avoid false alarms caused by dynamic entry and exit of personnel in the safe operation area.

[0046] According to one embodiment of the present invention, the monitoring method further includes:

[0047] In response to the pre-power transmission information in the power grid data information, determine the power transmission and distribution lines in the pre-power transmission information, and obtain the status information of the grounding knife switch on the power transmission and distribution line and the status information of the grounding short-circuit device in the associated intelligent tool; determine the number of grounding short-circuit devices in the intelligent tools associated with the power transmission and distribution line that are in the installed state, and the number of grounding knife switches in the closed state; when the number of grounding short-circuit devices in the installed state or the number of grounding knife switches in the closed state is not zero, issue an alarm message that the grounding short-circuit device is not completely removed, the grounding short-circuit device is left on the power transmission and distribution line, and the grounding knife switch is improperly closed. Among them, the cooperation state or the opening state of the grounding knife switch can be directly determined through the ledger information of the power grid data. The monitoring here can prevent the risk of "closing with grounding wire" from occurring.

[0048] According to a second aspect of the present invention, a safety tool system is provided, the system comprising a plurality of grounding short-circuit devices, a plurality of intelligent safety belts, a plurality of intelligent work cards and a background subsystem; wherein the grounding short-circuit device is configured to obtain connection status information and positioning positions of the grounding short-circuit device, determine the installation status of the grounding short-circuit device according to the obtained connection status information, and send the determined installation status and positioning position; the intelligent safety belt is configured to obtain height information and positioning position of the intelligent safety belt, and determine the climbing movement trend of the intelligent safety belt through the obtained height information and positioning information; and switch the operation state of the climbing operation based on the determined climbing movement trend, and send the operation state and positioning position in real time; the intelligent work card is configured to obtain vibration start information and positioning position of the intelligent work card, and determine the state information of the intelligent work card according to the intelligent work card start information, and send the positioning position corresponding to the state information and the stored identity information; the background subsystem receives the information sent by the grounding short-circuit device, the intelligent safety belt and the intelligent work card, and executes the monitoring method provided by the first aspect of the present invention.

[0049] In the process of determining the installation status of the grounding short-circuit device, according to one embodiment of the present invention, the installation status of the grounding short-circuit device is determined according to the acquired connection status information through the following steps: the installation status is determined according to the detection status of the grounding end connection signal and the conductor end connection signal; wherein, when both the grounding end connection signal and the conductor end connection signal do not exist, the installation status is marked as a ready-to-use status; when it is detected that the grounding end connection signal changes from non-existence to existence, and the conductor end connection signal does not exist, the installation status is marked as a start installation status; when the grounding end connection signal and the conductor end connection signal both exist, the installation status is marked as a completed grounding short-circuit status; when it is monitored that the conductor end connection signal changes from existence to non-existence, the installation status is marked as a start removal status.

[0050] It should be noted that when the ground short-circuit device is being installed, the positioning device, the pressing sensor, and the hook sensor group will generate corresponding signals. When the conductor end connection signal is generated by multiple sensors, preferably when multiple sensors all generate pressure signals, it is determined that the conductor end connection signal exists. By detecting the presence or change process of the ground end connection signal and the conductor end connection signal, the installation status of the ground short-circuit device can be well determined.

[0051] It should be noted that the state judgment of the smart safety belt can refer to the patent technology that has been disclosed. For example, it is preferred to switch the working state by referring to the current working state and the current climbing movement trend.

[0052] Specifically, the smart safety belt determines the state in the following manner. The climbing movement trend is determined based on the acquired height information and position information, and the operation state of the climbing operation is switched based on the determined climbing movement trend. According to one embodiment of the present invention, the climbing movement trend is determined by the following steps: T1, obtaining the position information obtained within the positioning reference time period, and determining the positioning change state within the positioning reference time period; T2, when the positioning change state determined in the step T1 is that the positioning is unchanged, obtaining multiple height information received within the climbing state reference time period, and calculating the height change amount of the climbing state reference time based on the multiple height information; T3, judging the climbing movement trend based on the height change amount calculated in the step T2 and the preset trend threshold.

[0053] It should be noted that in order to improve the accuracy of the climbing movement trend, this application introduces location information to eliminate interference in judgment. For example, when location information (for example, 5) is obtained within a positioning reference time period (for example, 1 minute), the mean square error of these 5 location information is calculated. When the mean square error is less than a preset value (for example, 2), the influence of the detection accuracy of the location information can be eliminated. At this time, judging the height change within a climbing state reference time period can ensure that the user enters the climbing operation and prevent false alarms of safety information. Among them, the preset trend threshold includes a pole climbing threshold, a height operation threshold and a pole lowering threshold. When the height change is greater than the pole climbing threshold, the climbing movement trend is rising, for example, the climbing state reference time is 10 seconds, the height change is positive 1 meter, and the pole climbing threshold is set to 0.3 meters; when the height change is less than or equal to the height operation threshold (equivalent to a small height change), the climbing movement trend is stable, for example, the climbing state reference time is 10 seconds, the height change is 0 meters, and the height operation threshold is set to 0~0.2 meters; when the height change is less than the pole lowering threshold, the climbing movement trend is falling, for example, the climbing state reference time is 10 seconds, the height change is negative 1 meter, and the pole lowering threshold is set to negative 0.3 meters. The required thresholds can be optimally set according to specific experimental results, which will not be repeated here.

[0054] In the part of generating the working status, the following method is used to switch the working status of the climbing work based on the determined climbing movement trend: N1, obtain the current working status and the current climbing movement trend; N2, generate a switching signal according to the current working status and the climbing movement trend obtained in the step N1, and switch the working status based on the switching signal, wherein the switching signal includes a first switching signal, a second switching signal and a third switching signal, and when the switching signal is the first switching signal, the working status is switched from the climbing preparation stage to the pole climbing stage; when the switching signal is the second switching signal, the working status is switched from the pole climbing stage to the high-altitude working stage, and when the switching signal is the third switching signal, the working status is switched from the high-altitude working stage to the pole lowering stage.

[0055] It should be noted that the setting of the switching signal can well convert the possible climbing movement trend during the climbing operation into a trigger signal for calling the monitoring logic, further improving the accuracy of the entire monitoring process. Furthermore, in order to improve the accuracy of generating the switching signal, according to an embodiment of the present invention, in the step N2, the switching signal is generated in the following manner: when the current operating state is the climbing preparation stage and the current climbing movement trend is rising, a first switching signal is generated; when the current operating state is the pole climbing stage and the current climbing movement trend is stable, a second switching signal is generated; when the current operating state is the high-altitude operation stage and the current climbing movement trend is descending, a third switching signal is generated. In addition, the setting of the switching signal can make the change of the operating state based on the state switching performed after the climbing preparation stage, so that the entire process is monitored under the condition that the sensor failure is eliminated, thereby improving the safety of the climbing operation process.

[0056] It should be noted that the principle of the safety tool system has been described in the monitoring method and will not be repeated here.

[0057] The present invention makes full use of the linkage analysis of multiple safety tools and can also make full use of multiple real-time information data of power grids for multi-data linkage analysis, so as to effectively monitor the safety risks that pose the greatest threat to the personal safety of operators and power grids and have the most serious impact, such as the following safety risks (the grounding and short-circuiting devices are not installed comprehensively or the grounding switches are not closed properly, and the devices are not installed on all sides of the power outage maintenance equipment that may receive power (it can also be understood as the failure to install grounding and short-circuiting devices at the set positions or to close the lines where the grounding switches are located); operators install grounding and short-circuiting devices while energized; operators operate beyond the protection range of the grounding and short-circuiting devices and mistakenly climb live poles and towers; aerial operations lose protection; grounding and short-circuiting devices are not completely removed, grounding and short-circuiting devices are left on power equipment, and grounding switches are improperly closed; transmission and distribution line operations are carried out without an operation plan; the person in charge of the work leaves the operation site) can all be effectively monitored. Specifically, comprehensive monitoring is carried out by utilizing the information sent by a variety of intelligent safety tools and a variety of information in the power grid database, and warnings are issued for high risks that affect the safety of power transmission and distribution line construction operations and are likely to cause personal and power grid accidents, thereby achieving timely and accurate warnings for the above-mentioned serious violations, and effectively improving the safety monitoring level of power transmission and distribution line construction operations. In addition, the present invention has designed corresponding monitoring logic to monitor the transmission and distribution line construction operations and issue corresponding alarm information, which can effectively monitor the transmission and distribution line construction operations while effectively improving the safety of power construction operations.
