Description

Technical Field

[0001] The present invention relates to the technical field of substation construction, and in particular to a substation construction operation safety protection system. Background Art

[0002] With the rapid development of social economy, the demand for electricity has increased dramatically. In order to meet the electricity needs of people's lives and production, whether the substation can operate safely and stably is an important task related to the national economic development. In terms of substation site safety management, major power companies are also constantly conducting risk analysis and management. However, in the current substation site management, production safety accidents still occur from time to time. The causes of substation site safety accidents mainly include unsafe factors in the construction environment, abnormal conditions of operating machinery and equipment, and illegal behaviors of construction workers. Accidents are caused by the interaction of these factors. Unsafe factors in the working environment constitute safety risks, which are mainly determined by the type and size of the substation site construction tasks. At present, the following problems exist in the substation construction site safety risk management:

[0003] 1. The operation of construction machinery is difficult;

[0004] At substation construction sites, equipment is widely distributed and space is compact. Heavy machinery like large cranes and insulated bucket trucks require a three-dimensional spatial protection system to prevent movement and impact on equipment. Furthermore, during construction, some drivers lack awareness of site conditions and ignore safety signs and height restrictions, creating hidden dangers for substation safety.

[0005] 2. Risk analysis and hazard identification at the work site are not in place;

[0006] Compared to other construction projects, substation construction is more complex, challenging, and carries a higher safety risk index. To ensure the safety of on-site construction workers, relevant personnel must conduct on-site hazardous point identification before construction begins. These identified hazardous points must be managed and controlled to prevent accidents. Furthermore, due to the wide scope of substation projects, both internal and external personnel are often involved. This mixed workforce, with varying levels of professional competence and safety awareness, complicates on-site supervision. This is particularly challenging when external personnel are required to collaborate with various work teams.

[0007] 3. Frequent violations on site;

[0008] At substation construction sites, some construction workers are temporary hires with poor safety awareness and a lack of in-depth understanding of substation construction site management requirements. Furthermore, some outside contractors fail to properly manage temporary workers, leading to them being prone to unconscious violations and increasing the risk of violations on the construction site. For example, dedicated passages for construction workers are required at substation construction sites. Temporary fences must be maintained with movable barriers, designated patrol routes, and signage must be installed. However, actual investigations revealed that some construction workers, in an effort to save time, would step over the fences and stop near live equipment, creating safety hazards. Summary of the Invention

[0009] The technical problem to be solved by the present invention is to provide a substation construction operation safety protection system and method in view of the deficiencies of the above-mentioned prior art.

[0010] The technical solution of the present invention to solve the above technical problems is as follows: A substation construction operation safety protection system includes multiple sensing units, multiple monitoring devices, a signal processing unit, a background terminal and an alarm protection unit;

[0011] The plurality of sensing units are respectively arranged at corner positions corresponding to the substation construction area, and monitor the intrusion status information of the substation construction area in real time;

[0012] The plurality of monitoring devices are respectively arranged on corresponding monitoring targets and are used to obtain monitoring data information of the corresponding monitoring targets in real time, wherein the monitoring targets include power facilities and operating personnel;

[0013] A backend terminal is used to initialize the location information of the sensing unit and the power facilities in the substation construction area, construct a three-dimensional model of the substation construction area, and determine a safe operating range within the three-dimensional model of the substation construction area according to preset operating standards;

[0014] The signal processing unit is configured to perform signal processing on the monitoring data information according to the intrusion status information to generate real-time operation parameter information including at least posture information and motion information of the monitoring target;

[0015] The backend terminal is used to determine whether the monitoring target is within the corresponding safe operating range according to the real-time operating parameter information, and generate alarm protection information when the monitoring target exceeds the corresponding operating range;

[0016] The alarm protection unit is arranged in the construction area of ​​the substation and is used to send out an audible and visual alarm signal according to the alarm protection information.

[0017] The beneficial effects of the present invention are as follows: the substation construction operation safety protection system of the present invention senses the intrusion status information of the substation construction area in real time through the sensing unit, so that when the substation construction area is invaded, the monitoring data information of the monitoring target can be obtained in real time through the monitoring device, thereby facilitating the acquisition of real-time operation parameter information to determine whether the monitoring target is within the corresponding safe operation range, thereby achieving full coverage of monitoring of the substation construction area, accessing the application platform, and realizing efficient and unified management of the substation construction area by the platform, thereby solving the shortcomings of insufficient safety prevention capabilities at power construction sites.

[0018] On the basis of the above technical solution, the present invention can also be improved as follows:

[0019] Further: the sensing unit includes a magnetic wave detection device and a video monitoring device;

[0020] The magnetic wave detection equipment is arranged at a corner position corresponding to the substation construction area, and is used to generate and transmit electromagnetic waves in real time according to preset parameters, and the superposition area formed by the electromagnetic waves emitted by all the magnetic wave detection equipment completely covers the substation construction area;

[0021] The video surveillance equipment is arranged in the substation construction area, and the overlapping area formed by the fields of view of all the video surveillance equipment completely covers the substation construction area.

[0022] The beneficial effect of the above further solution is that the magnetic wave detection equipment can detect in real time whether there is an intrusion in the substation construction area, achieve full coverage of the entire substation construction area, and ensure the safety of the substation construction area.

[0023] Further: the magnetic wave detection equipment includes a retractable frame rod, an adapter plate, a support seat and a magnetic wave detector, the adapter plate is arranged at the upper end of the support seat, a through hole adapted to the frame rod is arranged in the middle of the adapter plate, the frame rod is installed in the support seat through the through hole, and the magnetic wave detector is movably arranged at the upper end of the frame rod.

[0024] The beneficial effect of the above further scheme is that the pole and the support seat can provide better support for the magnetic wave detector, and the magnetic wave detector can realize intrusion monitoring in the substation construction area, and the adapter plate facilitates a stable connection between the pole and the support seat.

[0025] Further: the support seat includes multiple outer support rods and support pads that are the same in number and correspond one to one to the outer support rods, and the multiple outer support rods are distributed circumferentially around the support seat, and the upper ends of the outer support rods are rotatably connected to the support seat, and the lower ends of the outer support rods are rotatably connected to the corresponding support pads.

[0026] The beneficial effect of the above further solution is that the frame rod can be conveniently supported circumferentially by the outer support rod, and the support pad can increase the force-bearing area to ensure the support stability of the entire support seat.

[0027] Further: the magnetic wave detection equipment also includes a counterweight block, which is arranged at the lower end of the rack.

[0028] The beneficial effect of the above further solution is that by providing the counterweight block, the frame rod can be easily counterweighted, thereby lowering the center of gravity of the entire support base, making the entire support base more stable and not easy to tip over.

[0029] Further: the backend terminal determines the safe operation range in the three-dimensional model of the substation construction area according to the preset operation standard in a specific implementation as follows:

[0030] Determining the initial spatial location information of the power facilities based on the three-dimensional model of the substation construction area, and determining the corresponding operation warning lines according to the preset operation standards corresponding to each of the power facilities;

[0031] Extending and intersecting all operation warning lines of the power facility to form a dangerous operation area corresponding to the power facility;

[0032] The safe operating range within the three-dimensional model of the substation construction area is determined based on the overlapping range of the dangerous operating areas of all the power facilities.

[0033] The beneficial effect of the above further scheme is: by combining the three-dimensional model of the substation construction area with the initial spatial position information of each power facility, the relative position relationship between each power facility and the three-dimensional model of the substation construction area can be determined, and then the corresponding preset operating standards of the power facilities can be combined to obtain the corresponding operating warning line of each power facility, which serves as a reference for the subsequent movement of the monitoring target operation. Finally, the dangerous operating area can be determined based on all the operating warning lines, and then the safe operating range outside the dangerous operating area can be obtained, thereby ensuring that the monitoring target corresponding to the monitoring is carrying out construction operations within the safe operating range.

[0034] Further: the backend terminal determines whether the monitoring target is within the corresponding safe operation range according to the real-time operation parameter information in a specific implementation as follows:

[0035] Reading motion information of all the monitored targets in real time according to the real-time operation parameter information, generating a three-dimensional motion scene according to the motion information, and loading the three-dimensional motion scene into the three-dimensional model of the substation construction area;

[0036] The motion information includes at least motion trajectory, motion speed and motion direction;

[0037] Reading the position information of all the monitoring targets in real time according to the real-time operation parameter information, and calculating the minimum distance between the monitoring targets and the boundary of the safe operation range according to the position information of the monitoring targets;

[0038] The minimum distance is compared with a corresponding preset distance threshold, and when the minimum distance is greater than the preset distance threshold, it is determined that the monitoring target is within the corresponding safe operating range.

[0039] The beneficial effect of the above further scheme is: a three-dimensional motion scene is generated by combining the motion information of the monitoring target with the three-dimensional model of the substation construction area, so that a visual interface can be conveniently formed through the background terminal, which is convenient for background personnel to understand in real time. At the same time, combined with the posture information of the monitoring target, the minimum distance between the monitoring target and the boundary of the safe operating range can be accurately calculated within the three-dimensional model of the substation construction area, so that it can be accurately judged whether the monitoring target is located in the corresponding safe operating range, and an audible and visual alarm can be issued when it exceeds the safe operating range.

[0040] The present invention also provides a substation construction operation safety protection method, comprising the following steps:

[0041] Multiple sensing units are set up at the corners corresponding to the substation construction area to monitor the intrusion status information of the substation construction area in real time;

[0042] When the substation construction area is invaded, multiple monitoring devices installed on corresponding monitoring targets respectively obtain monitoring data information of corresponding monitoring targets in real time, and the monitoring targets include power facilities and operating personnel;

[0043] Initializing the location information of the sensing unit and the power facilities in the substation construction area, constructing a three-dimensional model of the substation construction area, and determining a safe operating range within the three-dimensional model of the substation construction area according to preset operating standards;

[0046] An alarm protection unit arranged in the construction area of ​​the substation sends an audible and visual alarm signal according to the alarm protection information.

[0047] The substation construction operation safety protection method of the present invention uses the sensing unit to sense the intrusion status information of the substation construction area in real time, so that when the substation construction area is invaded, the monitoring data information of the monitoring target can be obtained in real time through the monitoring device, thereby facilitating the acquisition of real-time operation parameter information to determine whether the monitoring target is within the corresponding safe operation range, thereby achieving full coverage of monitoring of the substation construction area, accessing the application platform, and realizing efficient and unified management of the substation construction area by the platform, thereby solving the shortcomings of insufficient safety prevention capabilities at power construction sites.

[0054] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0055] like Figure 1 As shown, a substation construction operation safety protection system includes multiple sensing units, multiple monitoring devices, a signal processing unit, a background terminal and an alarm protection unit;

[0056] The plurality of sensing units are respectively arranged at corner positions corresponding to the substation construction area, and monitor the intrusion status information of the substation construction area in real time;

[0057] The plurality of monitoring devices are respectively arranged on corresponding monitoring targets and are used to obtain monitoring data information of the corresponding monitoring targets in real time, wherein the monitoring targets include power facilities and operating personnel;

[0058] A backend terminal is used to initialize the location information of the sensing unit and the power facilities in the substation construction area, construct a three-dimensional model of the substation construction area, and determine a safe operating range within the three-dimensional model of the substation construction area according to preset operating standards;

[0059] The signal processing unit is configured to perform signal processing on the monitoring data information according to the intrusion status information to generate real-time operation parameter information including at least posture information and motion information of the monitoring target;

[0060] The backend terminal is used to determine whether the monitoring target is within the corresponding safe operating range according to the real-time operating parameter information, and generate alarm protection information when the monitoring target exceeds the corresponding operating range;

[0061] The alarm protection unit is arranged in the construction area of ​​the substation and is used to send out an audible and visual alarm signal according to the alarm protection information.

[0062] The substation construction operation safety protection system of the present invention uses the sensing unit to sense and monitor the intrusion status information of the substation construction area in real time. In this way, when the substation construction area is invaded, the monitoring data information of the monitoring target can be obtained in real time through the monitoring device, thereby facilitating the acquisition of real-time operation parameter information to determine whether the monitoring target is within the corresponding safe operation range, thereby achieving full coverage of monitoring of the substation construction area, accessing the application platform, and realizing efficient and unified management of the substation construction area by the platform, thereby solving the shortcomings of insufficient safety prevention capabilities at power construction sites.

[0063] In one or more embodiments of the present invention, the sensing unit includes a magnetic wave detection device and a video monitoring device;

[0064] The magnetic wave detection equipment is arranged at a corner position corresponding to the substation construction area, and is used to generate and transmit electromagnetic waves in real time according to preset parameters, and the superposition area formed by the electromagnetic waves emitted by all the magnetic wave detection equipment completely covers the substation construction area;

[0065] The video surveillance equipment is arranged in the substation construction area, and the overlapping area formed by the fields of view of all the video surveillance equipment completely covers the substation construction area.

[0066] The magnetic wave detection equipment can detect in real time whether there is an intrusion in the substation construction area, achieve full coverage of the entire substation construction area, and ensure the safety of the substation construction area.

[0067] like Figure 2As shown, in one or more embodiments of the present invention, the magnetic wave detection equipment includes a retractable frame pole 1, an adapter plate 2, a support seat 3 and a magnetic wave detector 4, the adapter plate 2 is arranged at the upper end of the support seat 3, and a through hole adapted to the frame pole 1 is arranged in the middle of the adapter plate 2, the frame pole 1 is installed in the support seat 3 through the through hole, and the magnetic wave detector 4 is movably arranged at the upper end of the frame pole 1.

[0068] The pole 1 and the support seat 3 can provide good support for the magnetic wave detector 4, and the magnetic wave detector 4 can realize intrusion monitoring in the substation construction area. The adapter plate 2 facilitates a stable connection between the pole 1 and the support seat 3.

[0069] In practice, the magnetic wave detector 4 is placed at a suitable location in the construction area, usually at the corner of the substation construction area. According to the actual construction scope, it can be visited in the corner of the substation construction area to achieve full coverage of the substation construction area. Each magnetic wave detection device weighs 3.2 kilograms, so it is convenient to carry.

[0070] Since the mast 1 is retractable, it can be extended to the desired height according to the scale on the mast. The fastener screws are tightened to secure the height. A magnetic wave rangefinder 4 is installed at the top of the mast 1. The detection point will be illuminated red, and the distance between the transmitter and the charged object is displayed on the controller. This can be adjusted based on the actual detection distance. The transmitter's magnetic wave scanning range is adjusted using the controller. The detection range is adjustable up to 25 meters and can be adjusted to meet the needs of the actual construction site. After setup, the magnetic wave transmitter emits magnetic waves within the set sector-shaped sensing scanning area, emitting red dots along the scanning direction. The red dots confirm the sensing range. The sensing areas of each transmitter combine to form a detection barrier, quickly responding to people, vehicles, tools, etc. that touch the barrier. Since the transmitter's detection angle range can be expanded to a maximum of 270 degrees, two transmitters can also be used to form a warning barrier, depending on the actual situation.

[0071] It should be additionally pointed out that, during non-operation periods, in the present invention, the substation construction area can also be monitored by the magnetic wave detector 4. Since there are usually no operating personnel and operating equipment entering during non-operation periods, when a suspicious target enters the construction area during non-operation periods, the magnetic wave detector 4 will upload the intrusion information of the detected suspicious target to the background terminal. At the same time, the background terminal will also actively obtain the actual picture of the video surveillance equipment, so as to take timely measures to achieve all-round and three-dimensional protection and warning goals in the construction area.

[0072] In special application scenarios, the magnetic wave detector 4 can also be used alone, such as in small-scale construction. In order to avoid carrying too much equipment and occupying construction space, the magnetic wave detector 4 can be removed from the pole 1 and fixed to the scaffolding used in the construction with a special bracket fixing clip for easy use.

[0073] In one or more embodiments of the present invention, the support seat 3 includes a plurality of outer support rods 31 and support pads 32 that are the same in number and correspond one to one to the outer support rods 31. The plurality of outer support rods 31 are circumferentially spaced around the support seat 3, and the upper ends of the outer support rods 31 are rotatably connected to the support seat 3, and the lower ends of the outer support rods 31 are rotatably connected to the corresponding support pads 32.

[0074] The outer support rod 31 can facilitate circumferential support of the rack rod 1 , and the support pad 32 can increase the force-bearing area to ensure the support stability of the entire support base 3 .

[0075] Optionally, in one or more embodiments of the present invention, the magnetic wave detection device further includes a counterweight 5 , which is disposed at the lower end of the rack 1 .

[0076] By providing the counterweight block 5 , the rack rod 1 can be easily counterweighted, thereby lowering the center of gravity of the entire support base 3 , making the entire support base 3 more stable and less likely to fall over.

[0077] In one or more embodiments of the present invention, the monitoring device is an existing monitoring device with Beidou-GPS dual-mode positioning, and the specific monitoring principle will not be described in detail in the present invention.

[0078] In one or more embodiments of the present invention, the backend terminal determines the safe operating range within the three-dimensional model of the substation construction area according to the preset operating standards, specifically comprising the following steps:

[0079] Determining the initial spatial location information of the power facilities based on the three-dimensional model of the substation construction area, and determining the corresponding operation warning lines according to the preset operation standards corresponding to each of the power facilities;

[0080] Extending and intersecting all operation warning lines of the power facility to form a dangerous operation area corresponding to the power facility;

[0081] The safe operating range within the three-dimensional model of the substation construction area is determined based on the overlapping range of the dangerous operating areas of all the power facilities.

[0082] By combining the three-dimensional model of the substation construction area with the initial spatial position information of each power facility, the relative position relationship between each power facility and the three-dimensional model of the substation construction area can be determined. Then, combined with the preset operating standards corresponding to the power facilities, the operating warning line corresponding to each power facility can be obtained, which serves as a reference for the subsequent movement of the monitoring target. Finally, the dangerous operating area can be determined based on all the operating warning lines, and then the safe operating range outside the dangerous operating area can be obtained, thereby ensuring that the monitoring target corresponding to the monitoring is carrying out construction operations within the safe operating range.

[0083] For example, when workers are standing on scaffolding to perform maintenance and repairs on electrical equipment, there are safety hazards due to the presence of high-risk power facilities above - overhead cables. According to the preset operating standards, workers need to maintain a suitable minimum distance from the corresponding overhead cables. Therefore, according to the position of the overhead cables in the three-dimensional model of the substation construction area and the set minimum distance, the corresponding operating warning line can be determined and a dangerous operating area can be formed. Corresponding to this is the safe operating range within the three-dimensional model. If, during operation, the worker exceeds the corresponding safe operating range within the three-dimensional model, it is determined that there is a danger, an alarm protection information is generated, and an audible and visual alarm signal is sent through the corresponding alarm protection unit to alert the worker.

[0084] In one or more embodiments of the present invention, determining whether the monitoring target is within the corresponding safe operating range according to the real-time operating parameter information specifically includes the following steps:

[0085] Reading motion information of all the monitored targets in real time according to the real-time operation parameter information, generating a three-dimensional motion scene according to the motion information, and loading the three-dimensional motion scene into the three-dimensional model of the substation construction area;

[0086] The motion information includes at least motion trajectory, motion speed and motion direction;

[0087] Reading the position information of all the monitoring targets in real time according to the real-time operation parameter information, and calculating the minimum distance between the monitoring targets and the boundary of the safe operation range according to the position information of the monitoring targets;

[0088] The minimum distance is compared with a corresponding preset distance threshold, and when the minimum distance is greater than the preset distance threshold, it is determined that the monitoring target is within the corresponding safe operating range.

[0089] A three-dimensional motion scene is generated by combining the motion information of the monitoring target with the three-dimensional model of the substation construction area, so that a visual interface can be formed through the background terminal, which is convenient for background personnel to understand in real time. At the same time, combined with the posture information of the monitoring target, the minimum distance between the monitoring target and the boundary of the safe operating range can be accurately calculated within the three-dimensional model of the substation construction area, so that it can be accurately judged whether the monitoring target is located in the corresponding safe operating range, and an audible and visual alarm can be triggered when it exceeds the safe operating range.

[0090] For example, when an operating vehicle enters the substation construction area, the motion information of the operating vehicle can be read in real time according to the monitoring device on the operating vehicle, and then a dynamic three-dimensional operation scene of the operating vehicle can be generated according to the motion information of the operating vehicle, and the three-dimensional operation scene can be loaded into the three-dimensional model of the substation construction area. In this way, the operating dynamics of the operating vehicle can be understood more conveniently and intuitively; at the same time, the signal processing unit can obtain the real-time operating parameter information of the operating vehicle according to the monitoring data information actually obtained by the monitoring device on the operating vehicle, such as the operating vehicle posture information, the operating vehicle status, etc., and then the minimum distance between the operating vehicle (regarded as a particle) and the boundary of the safe operating range can be calculated. When the minimum distance is greater than the preset distance threshold, it is determined that the monitoring target is within the corresponding safe operating range; otherwise, it is determined that the monitoring target is not within the corresponding safe operating range.

[0091] It's important to note that in practice, if monitoring targets overlap, such as one monitoring target placed on top of another, all monitoring targets must remain within the safe operating range. In practical applications, for example, if workers are standing on a work vehicle while performing construction work, both the workers and the vehicle must be within the safe operating range.

[0092] like Figure 3 As shown, the present invention also provides a substation construction operation safety protection method, comprising the following steps:

[0093] S1: Multiple sensing units are set up at the corners corresponding to the substation construction area to monitor the intrusion status information of the substation construction area in real time;

[0094] S2: When the substation construction area is invaded, multiple monitoring devices installed on corresponding monitoring targets respectively obtain monitoring data information of the corresponding monitoring targets in real time, and the monitoring targets include power facilities and operating personnel;

[0095] S3: Initializing the location information of the sensing unit and the power facilities in the substation construction area, constructing a three-dimensional model of the substation construction area, and determining a safe operating range within the three-dimensional model of the substation construction area according to preset operating standards;

[0096] S4: performing signal processing on the monitoring data information according to the intrusion status information to generate real-time operation parameter information including at least posture information and motion information of the monitoring target;

[0097] S5: determining whether the monitoring target is within a corresponding safe operating range according to the real-time operating parameter information, and generating alarm protection information when the monitoring target exceeds the corresponding operating range;

[0098] S6: The alarm protection unit arranged in the construction area of ​​the substation sends an audible and visual alarm signal according to the alarm protection information.

[0099] The substation construction operation safety protection method of the present invention uses the sensing unit to sense the intrusion status information of the substation construction area in real time, so that when the substation construction area is invaded, the monitoring data information of the monitoring target can be obtained in real time through the monitoring device, thereby facilitating the acquisition of real-time operation parameter information to determine whether the monitoring target is within the corresponding safe operation range, thereby achieving full coverage of monitoring of the substation construction area, accessing the application platform, and realizing efficient and unified management of the substation construction area by the platform, thereby solving the shortcomings of insufficient safety prevention capabilities at power construction sites.

[0100] In one or more embodiments of the present invention, determining a safe operating range within the three-dimensional model of the substation construction area according to preset operating standards specifically includes the following steps:

[0101] S31: determining initial spatial location information of power facilities according to the three-dimensional model of the substation construction area, and determining corresponding operation warning lines according to preset operation standards corresponding to each power facility;

[0102] S32: Extending and intersecting all operation warning lines of the power facility to form a dangerous operation area corresponding to the power facility;

[0103] S33: Determine a safe operating range within the three-dimensional model of the substation construction area according to the overlapping range of the dangerous operating areas of all the power facilities.

[0104] By combining the three-dimensional model of the substation construction area with the initial spatial position information of each power facility, the relative position relationship between each power facility and the three-dimensional model of the substation construction area can be determined. Then, combined with the preset operating standards corresponding to the power facilities, the operating warning line corresponding to each power facility can be obtained, which serves as a reference for the subsequent movement of the monitoring target. Finally, the dangerous operating area can be determined based on all the operating warning lines, and then the safe operating range outside the dangerous operating area can be obtained, thereby ensuring that the monitoring target corresponding to the monitoring is carrying out construction operations within the safe operating range.

[0105] In one or more embodiments of the present invention, determining whether the monitoring target is within the corresponding safe operating range according to the real-time operating parameter information specifically includes the following steps:

[0106] S51: reading motion information of all the monitored targets in real time according to the real-time operation parameter information, generating a three-dimensional motion scene according to the motion information, and loading the three-dimensional motion scene into the three-dimensional model of the substation construction area;

[0107] The motion information includes at least motion trajectory, motion speed and motion direction;

[0108] S52: reading the position information of all the monitoring targets in real time according to the real-time operation parameter information, and calculating the minimum distance between the monitoring targets and the boundary of the safe operation range according to the position information of the monitoring targets;

[0109] S53: Compare the minimum distance with a corresponding preset distance threshold, and determine that the monitoring target is located within a corresponding safe operating range when the minimum distance is greater than the preset distance threshold.

[0110] A three-dimensional motion scene is generated by combining the motion information of the monitoring target with the three-dimensional model of the substation construction area, so that a visual interface can be formed through the background terminal, which is convenient for background personnel to understand in real time. At the same time, combined with the posture information of the monitoring target, the minimum distance between the monitoring target and the boundary of the safe operating range can be accurately calculated within the three-dimensional model of the substation construction area, so that it can be accurately judged whether the monitoring target is located in the corresponding safe operating range, and an audible and visual alarm can be triggered when it exceeds the safe operating range.

[0111] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
