Description

Technical Field

[0001] The present invention relates to the technical field of safety fence installation, and in particular to a method, system and medium for setting an intelligent safety fence for station operations. Background Art

[0002] The operational status of numerous electrical devices within a substation is crucial to its proper functioning. Regular testing, inspection, and maintenance are required for these devices. These inspections include testing the insulation performance and operating status of these devices to ensure proper operation. Safety fences are often used to isolate the work area during operations to prevent potential safety incidents.

[0003] Existing safety fences are still relatively traditional. During power operations, misoperation of other equipment may also affect the operation results. A large number of personnel are required to monitor the operation, resulting in excessive labor costs. In addition, the setting of safety fences mainly includes the operation area, ignoring the potential misoperation risk areas during power operations. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that traditional safety fences require a large number of personnel to monitor during the operation process, resulting in excessive labor costs, and the setting of safety fences mainly includes the operation area, ignoring the potential risk areas of misoperation during the power operation process; the purpose of the present invention is to provide an intelligent safety fence setting method, system and medium for station operation; to make methodological and structural improvements on the existing safety fence layout technology; in combination with the actual power work needs and the characteristics of the power work station, a safety fence setting strategy is obtained according to the basic data of the station and the operation data, and the misoperation area and the operation area are determined, and the combination of the misoperation area and the operation area is used as the safety fence area; it can be applied to different working environments, and it is also convenient for test personnel to know the situation around the operation and reasonably arrange the safety fence. The safety fence structure provided by the present invention is simple in principle, easy to transport, install and store, and can be applied to various power operation environments, reducing the safety hazards of non-test personnel entering the test area at will.

[0005] The present invention is achieved through the following technical solutions:

[0006] This solution provides a method for setting up an intelligent safety fence for station operations, including:

[0007] Obtaining basic data and operation data of the station; the operation data includes: operation items and operation target equipment; the basic data of the station includes: station area and location of each equipment in the station;

[0008] Analyze the basic data of the station and the operation data to obtain a safety fence strategy: determine the misoperation area and the operation area based on the basic data of the station and the operation data, and use the combination of the misoperation area and the operation area as the safety fence area;

[0009] Set up a security fence according to the security fence setting strategy.

[0010] Working principle of this solution: Traditional safety fences require a large number of personnel to monitor during the operation process, resulting in excessive labor costs, and the setting of safety fences mainly includes the operation area, ignoring the potential risk areas of false operation during power operations; this solution provides an intelligent safety fence setting method for station operations; it makes methodological improvements on the existing safety fence deployment technology; based on the actual needs of power work and the characteristics of power work stations, it obtains a safety fence setting strategy based on the basic data of the station and the operation data, determines the false operation area and the operation area, and uses the combination of the false operation area and the operation area as the safety fence area; it can be applied to different working environments, and it is also convenient for test personnel to know the situation around the operation and reasonably deploy safety fences.

[0011] A further optimization solution is that the safety fence strategy is obtained by analyzing the basic data of the station and the operation data, and further includes:

[0012] Divide the work items into multiple danger levels in advance, and divide the warning methods of the safety fence into multiple warning levels;

[0013] Get the operation project and set the safety fence warning method according to the operation project: the higher the danger level of the operation project, the higher the alarm level of the warning method.

[0014] Traditional safety fences can only serve as isolation and cannot provide effective warnings for substation test personnel. During the test, although safety warning fences are installed, multiple supervisors are still required around the operating area, which requires a large amount of manpower. The specific operating status inside the safety fence cannot be known from outside the safety fence. The safety fence provided by this solution uses different warning methods to distinguish different levels of danger in the operation projects, and promptly warns external personnel of the operating status inside the safety fence, reducing the safety hazards caused by non-operating personnel accidentally entering the test area, while significantly reducing the investment in supervisors.

[0015] A further optimization scheme is that the acquisition of operation data includes the following method:

[0016] Divide the overall area of ​​the station into multiple sub-areas; all equipment within the overall area of ​​the station is located in the sub-areas;

[0017] Statistics of work items, equipment and their locations, as well as circuit topology data for each sub-area.

[0018] Further optimization solutions include:

[0019] The entire station area is divided into even grids so that all devices within the entire station area are divided into sub-areas. During the division process, if device a is located on the dividing line between sub-area A and sub-area B, the area S of device a in sub-area A is calculated. Aa And the area S where device a falls in sub-area B Ba If S Aa >S Ba , then divide the entire area of ​​device a into sub-area A; if S Aa <S Ba , then the entire area of ​​device a is divided into sub-area B.

[0020] A further optimization solution is that the sub-region division method also includes:

[0021] Set the maximum area S of the sub-region max , select the sub-area by satisfying all the selection conditions;

[0022] The selection conditions include:

[0023] A, the area of ​​the sub-region selected by the box ≤ the maximum area S max ;

[0024] B, the selected sub-area contains at least one device;

[0025] C, the boxed sub-region preferentially contains the largest number of devices.

[0026] The further optimization scheme is as follows: S1, obtain the operation items, operation target equipment and circuit topology data of the sub-area;

[0027] S2, implements the operation project on the simulation software based on the circuit topology data, and performs malfunction tests on the equipment in the sub-area to obtain dangerous malfunction equipment; specifically, dangerous malfunction equipment is a device that, during the implementation of the operation project, malfunctions of device A in the sub-area, which may cause short circuits, open circuits and other faults.

[0028] S3, drawing a rectangular bounding box based on the position of the dangerous malfunction equipment and the position of the operation target equipment, and using the rectangular bounding box as the malfunction area;

[0029] S4, determining a work area based on the position of the work target device.

[0030] This solution also provides an intelligent safety fence setting system for station operations, which is used to implement the above-mentioned intelligent safety fence setting method for station operations; the system includes:

[0031] The acquisition module is used to obtain basic data and operation data of the station; the operation data includes: operation items and operation target equipment; the basic data of the station includes: station area and location of each equipment in the station;

[0032] An analysis module is configured to analyze the basic data of the station and the operation data to obtain a safety fence strategy: a misoperation zone and an operation zone are determined based on the basic data of the station and the operation data, and the combination of the misoperation zone and the operation zone is used as the safety fence area;

[0033] An output module is used to output the safety fence setting strategy.

[0034] A further optimized solution is that the safety fence includes:

[0035] Soft safety fence, used to be set up outside the working area;

[0036] A support frame, used to support the safety belt; the safety belt is arranged on multiple support frames;

[0037] The warning module is used to display the warning mode corresponding to different operation items; the warning module is set on the surface of the soft safety fence, and the warning display module is electrically connected to the output module.

[0038] Traditional safety fences are mainly folding safety fences made of traditional hard fiberglass materials. They are heavy and inconvenient to carry, and their environmental adaptability is not high enough, making them inconvenient to transport, install and store. This solution uses a strip-shaped safety fence, which not only reduces the weight, but also allows the safety belt to be rolled up when not in use, making it easy to store, carry and install. The warning display module is a color-changing LED light set on the surface of the safety belt. The color-changing LED light can emit different lights according to different hazard levels. The LED light can also be set to flash for warning.

[0039] A further optimization solution is that the safety fence also includes a detection module; the detection module is used to detect people who are less than the safety distance from the safety fence; the detection module is set on the soft safety fence; and the detection module is electrically connected to the warning module.

[0040] Inside and outside the safety fence, the detection module is an infrared sensing module. When the infrared sensing module senses that someone is approaching, it can provide a timely warning. In addition, the sensing range of the infrared sensing module inside the safety fence is smaller than that outside the safety fence.

[0041] This solution also provides a computer-readable medium having a computer program stored thereon, and the computer program is executed by a processor to implement the above-mentioned method for setting up an intelligent safety fence for station operations.

[0042] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0043] The present invention provides a method, system and medium for setting up an intelligent safety fence for station operations; it makes methodological improvements on the existing safety fence deployment technology; in combination with the actual needs of power work and the characteristics of the power work station, a safety fence deployment strategy is obtained according to the basic data of the station and the operation data, and the false operation area and the operation area are determined, and the combination of the false operation area and the operation area is used as the safety fence area; it can be applied to different working environments, and it is also convenient for test personnel to know the situation around the operation and reasonably deploy the safety fence.

[0051] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with examples and drawings. The exemplary embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0052] Traditional safety fences require a large number of personnel to monitor during the operation process, resulting in excessive labor costs. In addition, the setting of safety fences mainly includes the operation area, ignoring the potential risk areas of misoperation during power operations. In view of this, the present invention provides the following embodiments to solve the above technical problems.

[0053] Example 1

[0054] This embodiment provides a method for setting up an intelligent safety fence for station operations, such as Figure 1 Shown, including:.

[0055] Step 1: Obtain basic data and operation data of the station; the operation data includes: operation items and operation target equipment; the basic data of the station includes: station area and location of each equipment in the station;

[0056] The method of obtaining the operation data includes:

[0057] Divide the overall area of ​​the station into multiple sub-areas; all equipment within the overall area of ​​the station is located in the sub-areas;

[0058] Statistics of work items, equipment and their locations, as well as circuit topology data for each sub-area.

[0059] The sub-region division methods include:

[0060] The entire station area is divided into even grids so that all devices within the entire station area are divided into sub-areas. During the division process, if device a is located on the dividing line between sub-area A and sub-area B, the area S of device a in sub-area A is calculated. Aa And the area S where device a falls in sub-area B Ba If S Aa >S Ba , then divide the entire area of ​​device a into sub-area A; if S Aa <S Ba , then the entire area of ​​device a is divided into sub-area B.

[0061] This division method is suitable for scenarios where electrical equipment is evenly distributed, such as Figure 2 As shown in the figure, the circles represent electrical equipment, which are widely distributed and evenly spaced. Therefore, the area of ​​the entire station is evenly divided into four sub-areas.

[0062] The sub-region division method also includes:

[0063] Set the maximum area S of the sub-region max , select the sub-area by satisfying all the selection conditions;

[0064] The selection conditions include:

[0065] A, the area of ​​the sub-region selected by the box ≤ the maximum area S max ;

[0066] B, the selected sub-area contains at least one device;

[0067] C, the boxed sub-region preferentially contains the largest number of devices.

[0068] This division method is suitable for scenarios where electrical equipment is piled up and distributed, such as Figure 3 As shown in the figure, the circles are electrical equipment, which are concentrated and stacked, and the distance between each electrical equipment is almost uniform, so the maximum area of ​​the sub-area is set to S max , divided into 5 sub-areas according to the location of each electrical equipment, so that all electrical equipment are divided into one sub-area.

[0069] Step 2: Analyze the basic data of the station and the operation data to obtain a safety fence strategy: determine the misoperation area and the operation area based on the basic data of the station and the operation data, and use the combination of the misoperation area and the operation area as the safety fence area;

[0070] The analyzing the operation data to obtain the safety fence setting strategy also includes:

[0071] Divide the work items into multiple danger levels in advance, and divide the warning methods of the safety fence into multiple warning levels;

[0072] Get the operation project and set the safety fence warning method according to the operation project: the higher the danger level of the operation project, the higher the alarm level of the warning method.

[0073] Traditional safety fences can only serve as isolation and cannot provide effective warnings for substation test personnel. During the test, although safety warning fences are installed, multiple supervisors are still required around the operating area, which requires a large amount of manpower. The specific operating status inside the safety fence cannot be known from outside the safety fence. The safety fence provided by this solution uses different warning methods to distinguish different levels of danger in the operation projects, and promptly warns external personnel of the operating status inside the safety fence, reducing the safety hazards caused by non-operating personnel accidentally entering the test area, while significantly reducing the investment in supervisors.

[0074] The safety fence setting strategy obtained by analyzing the basic data of the station and the operation data includes:

[0075] S1, obtain the operation items, operation target equipment and circuit topology data of the sub-area;

[0076] S2, implements the operation project on the simulation software based on the circuit topology data, and performs malfunction tests on the equipment in the sub-area to obtain dangerous malfunction equipment; specifically, dangerous malfunction equipment is a device that, during the implementation of the operation project, malfunctions of device A in the sub-area, which may cause short circuits, open circuits and other faults.

[0077] S3, drawing a rectangular bounding box based on the position of the dangerous malfunction equipment and the position of the operation target equipment, and using the rectangular bounding box as the malfunction area;

[0078] S4, determining a work area based on the position of the work target device.

[0079] Step three: Set up a safety fence according to the safety fence setting strategy.

[0080] Example 2

[0081] This embodiment provides an intelligent safety fence setting system for station operations, such as Figure 4 As shown, a method for setting up an intelligent safety fence for station operations is used to implement Example 1; the system includes:

[0082] The acquisition module is used to obtain basic data and operation data of the station; the operation data includes: operation items and operation target equipment; the basic data of the station includes: station area and location of each equipment in the station;

[0083] An analysis module is configured to analyze the basic data of the station and the operation data to obtain a safety fence strategy: a misoperation zone and an operation zone are determined based on the basic data of the station and the operation data, and the combination of the misoperation zone and the operation zone is used as the safety fence area;

[0084] An output module is used to output the safety fence setting strategy.

[0085] The safety fence includes:

[0086] Soft safety fence, used to be set up outside the working area;

[0087] A support frame, used to support the safety belt; the safety belt is arranged on multiple support frames;

[0088] The warning module is used to display the warning mode corresponding to different operation items; the warning module is set on the surface of the soft safety fence, and the warning display module is electrically connected to the output module.

[0089] Traditional safety fences are not convenient to transport and store. This solution uses a soft safety fence, which not only reduces weight, but also allows the safety belt to be rolled up when not in use, making it easy to store and carry. The warning display module is a color-changing LED light set on the surface of the safety belt. The color-changing LED light can emit different lights according to different hazard levels. The LED light can also be set to flash for warning.

[0090] The safety fence also includes a detection module; the detection module is used to detect people whose distance from the safety fence is less than the safety distance; the detection module is arranged on the soft safety fence; the detection module is electrically connected to the warning module.

[0091] Inside and outside the safety fence, the detection module is an infrared sensing module. When the infrared sensing module senses that someone is approaching, it can provide a timely warning. In addition, the sensing range of the infrared sensing module inside the safety fence is smaller than that outside the safety fence.

[0092] like Figure 5 As shown, the detection module is an infrared sensing device, which determines whether someone has entered the working area and transmits the judgment result to the controller; the controller: processes the signal emitted by the infrared sensing device and the operating power supply signal, and controls the sound and light alarm device. When the operating power supply sends a working signal, the safety fence starts to light up. At this time, someone enters the working area, and the sound and light alarm device is controlled to issue a warning and send out an operating power trip signal at the same time; the sound and light alarm device consists of an audible alarm and an indicator light. When the controller does not send out a warning signal, the audible alarm device does not send out an alarm and the indicator light flashes green. When the controller sends out a warning signal, the audible alarm device sends out an alarm and the indicator light flashes red.

[0093] In view of the shortcomings of traditional safety warning fences in substations, such as low reliability, high labor costs, low work efficiency and safety hazards, the safety fence provided in this embodiment, the intelligent safety fence can ensure that test personnel can effectively, safely and quickly complete the electrical equipment testing work in the substation. It is suitable for working scenarios in different environments, reduces the safety hazards caused by non-test personnel accidentally entering the test area, and at the same time greatly reduces the input of supervisors and improves the efficiency of test work.
