[0034] The present disclosure is further described below in conjunction with the accompanying drawings and specific embodiments.

[0035] In order to solve the technical problem in the prior art that the existing electronic fence cannot adapt to complex three-dimensional space and cannot meet the safety requirements of high-voltage operations, the present invention provides a substation operation safety alarm method and related devices based on a point cloud model.

[0036] Figure 1 The flowchart of the step of the substation operation safety alarm method based on the point cloud model provided by the present disclosure is shown as follows: Figure 1 As shown, the substation operation safety alarm method based on the point cloud model includes the following steps:

[0037] S101, acquiring boundary information of a substation operation based on a point cloud model, wherein the boundary information includes latitude and longitude information and altitude information.

[0038] In this step, boundary information of the substation operation is obtained based on the point cloud model, and the boundary information includes latitude and longitude information and altitude information.

[0039] Specifically, when the substation is carrying out maintenance and inspection of high-voltage equipment, operators are required to perform simultaneous maintenance on equipment located on the ground and in the air; during the maintenance process, in order to ensure the safety of operators, it is necessary to shut down the power to the equipment within the maintenance range to prevent operators from getting electric shock. At the same time, in order to ensure the normal operation of the substation, equipment outside the maintenance range needs to be energized and operated normally. In this step, the boundary information of the substation operation is obtained, wherein the boundary information is used to indicate the power outage operation range of the substation. The boundary information includes latitude and longitude information and altitude information, that is, a specified three-dimensional space can be defined by the operation information, so that by obtaining the boundary information, the operation and maintenance area of ​​the substation can be accurately obtained.

[0040] Further, Figure 2 The flowchart of the steps for obtaining boundary information of substation operation provided by the present disclosure is shown as follows: Figure 2 As shown, obtaining boundary information of substation operation includes the following steps:

[0041] S201, obtaining work permit information.

[0042] In this step, work permit information is obtained.

[0043] Specifically, before performing work, the operator obtains work permission information, thereby determining that the area is a work area and the operator is an operator who has the authority to enter the work area to perform work.

[0044] During the substation operation process, each operator wears a card device with an internal personnel identity. The card device integrates a communication module, CPU, real-time dynamic measurement module, etc. Before the operator starts work, the card device can obtain work permit information through wireless communication to obtain permission to enter the work area.

[0045] S202: Acquire boundary information of the substation operation based on the work permission information.

[0046] After completing the above step S201, in this step, boundary information of the substation operation is obtained based on the work permission information.

[0047] Specifically, after the operator obtains the authority to enter the operating area, in this step, the boundary information of the substation operation is further obtained to determine whether the operator has the authority to enter the operating space for performing the operation.

[0048] In some embodiments, before obtaining boundary information of the substation operation, the method further includes: constructing a point cloud model of the substation, wherein the point cloud model includes location information, color information, and object surface reflection intensity information of the substation.

[0049] Specifically, the point cloud model is a three-dimensional expression of terrain and equipment facilities represented by a data set of discrete points in three-dimensional space, reflecting information such as the spatial position and geometric shape of the object.

[0050] The substation obtains a point cloud model in the LAS file format through lidar scanning. Each point in the model is defined by its three-dimensional coordinates, including the specific longitude, latitude and altitude, with an accuracy of centimeters. The point cloud model may also include color information (R, G, B) and surface reflection intensity information of the object.

[0051] When modeling the substation in 3D point cloud, first set the site and its scanning range according to the specific substation layout characteristics, to ensure full coverage of the 3D scanning while minimizing excessive overlap. At the same time, set the appropriate range and frequency parameters of the laser scanner according to the distance between the site and the specific facilities of the substation.

[0052] The data is processed by the scanner data processing software, and the collected three-dimensional point cloud data is imported into the HD_3LS_SCENE software for basic processing such as point cloud stitching, merging and noise reduction to obtain higher quality point cloud data. The substation cloud data obtained from the data processing software is imported into 3DMax, and then block modeling is performed according to the distribution of substation facilities. The three-dimensional models established in the blocks are assembled to form an integrated substation three-dimensional model. Finally, through image processing such as cropping, rotation, and color adjustment, a realistic substation three-dimensional model is obtained. The construction of the point cloud model diagram can adopt the existing modeling method, and the specific modeling method is not further limited in this disclosure.

[0053] Further, Figure 3 A flowchart of the steps of obtaining boundary information of a substation operation based on work permit information provided by the present disclosure is shown. As shown in FIG3 , the process of obtaining boundary information of a substation operation based on work permit information provided by the present disclosure includes the following steps:

[0054] S301: Select a power outage operation range in the point cloud model based on the work permission information.

[0055] In this step, the power outage operation range is framed in the point cloud model based on the work permit information.

[0056] Specifically, in order to conveniently and intuitively determine the operation area during the process of obtaining boundary information, after obtaining the operation command, the substation operator selects the range of the power outage equipment that needs to be worked on on the point cloud model of the substation, thereby selecting and determining the power outage operation range. This principle method makes the selection method simpler and can intuitively reflect the operation range, avoiding range demarcation errors caused by incorrect coordinate settings.

[0057] S302: Determine boundary information of the substation operation based on the frame selection.

[0058] After completing the above step S301, in this step, the boundary information of the substation operation is determined based on the box selection.

[0059] Specifically, after the operator selects a box on the point cloud model to determine the working range, the system reads the latitude, longitude and altitude information of the three-dimensional space boundary points of the working range to determine the boundary information of the operation.

[0060] In order to ensure the operating safety of the operation and maintenance personnel, after the power outage operation range is framed in the point cloud model, the method also includes checking the consistency of the framed interval with the power outage interval in the substation wiring diagram to prevent the operating personnel from mistakenly entering the energized interval.

[0061] S102, collecting the operation status information of the operation personnel.

[0062] After completing the above step S101, in this step, the operation status information of the operator is collected.

[0063] Specifically, collecting the working status information of the working personnel includes collecting the working status information of the working personnel based on real-time dynamic measurement technology, wherein the working status information includes the real-time latitude and longitude information and real-time altitude information of the working personnel; that is, determining the position information of the working personnel by determining the three-dimensional spatial coordinates of the working personnel.

[0064] Among them, real-time kinematic measurement (RTK) is a carrier phase differential technology, which is a differential method for processing the carrier phase observations of two measuring stations in real time. The carrier phase collected by the base station is sent to the user receiver to calculate the difference coordinates. In this disclosure, the existing real-time kinematic measurement method is used to solve the position coordinates of the operating personnel, and its specific measurement method is not further limited in this disclosure.

[0065] S103: Generate the warning information based on the boundary information and the status information.

[0066] After completing the above step S102, in this step, the warning information is generated based on the boundary information and the state information.

[0067] Further, Figure 4 The flowchart of the steps of generating the warning information based on the boundary information and the state information provided by the present disclosure is shown as follows: Figure 4 As shown, generating the warning information based on the boundary information and the state information includes the following steps:

[0068] S401: Compare the state information with the boundary information.

[0069] In this step, the state information is compared with the boundary information.

[0070] Specifically, after the status information of the operator is collected, the operation information is compared with the boundary information obtained through the point cloud model to determine whether the position of the operator is within the operation range interval in the point cloud model.

[0071] During the determination process, the latitude and longitude information is first used to determine whether the operator's working position is within the plane area defined by the point cloud model, and then the real-time height information is used to determine whether the operator's height position is within the height range defined by the point cloud model. This allows us to determine whether the operator's spatial position is within the spatial area defined by the point cloud model.

[0072] S402: If the status information is within the boundary information, the operation status information of the operator is collected again after a preset time interval.

[0073] After completing the above step S401, if the status information is within the boundary information, the operation status information of the operator is collected again after a preset time interval.

[0074] Specifically, after comparing the status information with the boundary information, if the status information is within the boundary information, it means that the operator is within a safe working area and there is no need to issue a warning message to the operator; at this time, after a preset time interval, the operator's working status information is collected again to determine the operator's real-time location information, wherein the preset time can be set according to the working range, for example, 0.5 seconds or 1 second.

[0075] S403: If the state information overlaps with the boundary information or is outside the boundary information, generate warning information.

[0076] After completing the above step S401, if the state information overlaps with the boundary information or is outside the boundary information, a warning message is generated.

[0077] Specifically, after comparing the state information with the boundary information, if the state information overlaps with the boundary information or is outside the boundary information, it means that the operator has exceeded the working space or is about to exceed the working space. At this time, a warning message is generated.

[0078] S104, generating sound and light alarm prompt information based on the early warning information.

[0079] After completing the above step S103, in this step, sound and light alarm prompt information is generated based on the early warning information.

[0080] Specifically, after the early warning information is generated, in this step, an audible and visual alarm prompt information is generated based on the early warning information. While the alarm light flashes, a prompt sound is emitted through a buzzer to remind the operator that he has exceeded the working range and needs to return to the designated working area immediately. This setting method is conducive to improving the perception efficiency of the operators and avoiding the operators' failure to discover the alarm prompt information in time.

[0081] In some embodiments of the present disclosure, while generating the sound and light alarm prompt information based on the early warning information, the method further includes: generating remote alarm prompt information based on the early warning information.

[0082] Specifically, while generating sound and light alarm prompt information to remind the operating personnel to immediately return to the designated working area, remote alarm prompt information is generated based on the early warning information, and the remote alarm prompt information is sent to the control room of the substation via a wireless network to remind other staff members to pay attention to possible dangerous situations, so that the operating personnel outside the working space can be reminded to return to the working space in time through other personnel. At the same time, it can also be pointed out that there may be dangerous situations and rescue measures need to be taken in time.

[0083] The substation operation safety alarm method based on the point cloud model provided by the present invention is applied to obtain the boundary information of the substation operation and collect the operation status information of the operators; and generate the early warning information based on the boundary information and status information; thereby generating sound and light alarm prompt information based on the early warning information, which can monitor the position of the operators in real time, reduce the risk of the operators mistakenly entering the energized interval, and improve the safety of high-voltage equipment maintenance.

[0084] In order to better implement the above method, the second aspect of the present disclosure further provides a substation operation safety alarm device based on a point cloud model, which can be integrated on an electronic device.

[0085] For example, Figure 5 As shown, the alarm device 200 may include: an acquisition module 210, a collection module 220, a first generation module 230 and a second generation module 240, which are specifically as follows:

[0086] (1) An acquisition module 210, which is used to acquire boundary information of the substation operation based on the point cloud model, wherein the boundary information includes latitude and longitude information and altitude information.

[0092] Furthermore, the first generating unit is also used to compare the status information with the boundary information; if the status information is within the boundary information, the operating status information of the operator is collected again after a preset time interval; if the status information coincides with the boundary information or is outside the boundary information, a warning message is generated.

[0093] Furthermore, the alarm device also includes a third generating module, and the third generating module is used to generate remote alarm prompt information based on the early warning information while generating sound and light alarm prompt information based on the early warning information.
