[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0042] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0043] In recent years, the state has placed increasing emphasis on workplace safety, stressing the need to firmly establish a safe development concept and promote the principles of prioritizing life and safety. During substation switching operations, accidental entry into energized compartments and misoperation by maintenance personnel are common causes of serious accidents, even resulting in injuries or fatalities. Currently, the main method to prevent accidents is the mandatory use of computerized five-proof keys to restrict the operational steps of maintenance personnel. However, these devices have limitations, such as the ability to unlock with universal keys and skip steps, and cannot completely prevent misoperation. There is an urgent need at work sites for a technical measure that can automatically identify whether maintenance personnel have accidentally entered energized compartments and monitor whether they are using the five-proof keys as required.
[0044] For the reasons mentioned above, this invention proposes a substation switching operation monitoring method based on BeiDou positioning technology, UWB positioning technology (Ultra Wideband) technology, and 3D (three-dimensional) modeling technology. This method enables automatic identification and real-time alarm for maintenance personnel accidentally entering energized compartments or performing unlocking operations. It has significant practical implications for ensuring the personal safety of on-site maintenance personnel, as well as the safety of equipment and the power grid in substations.
[0045] See Figure 1 , Figure 1 This invention provides a flowchart of a substation switching operation monitoring method, which can be applied to a monitoring backend. The method includes the following steps:
[0046] S10 establishes a three-dimensional model of each bay of equipment by locating the geographical coordinates of each bay of the substation.
[0047] In this embodiment of the invention, BeiDou positioning technology and UWB positioning technology can be used to create 3D models of each bay device in the substation, and these models can be stored in the storage module of the monitoring backend. It should be noted that the geographical coordinates of the bay devices in the 3D model can be reproduced 1:1.
[0048] Specifically, the geographical coordinates of outdoor bay equipment in the substation are recorded using BeiDou positioning technology, and the geographical coordinates of indoor bay equipment in the substation are recorded using UWB positioning technology. The geographical coordinates of the outdoor / indoor bay equipment are then used to create a 3D model, which is then stored in the storage module of the monitoring backend.
[0049] In the specific implementation process, step S10, "establishing a three-dimensional model of each bay device by locating the geographical coordinates of each bay device in the substation," can be performed as follows:
[0050] For each bay of equipment in the substation, determine the type of equipment for that bay;
[0051] If the interval device is an outdoor interval device, the geographical coordinates of the interval device are recorded using BeiDou positioning technology;
[0052] If the partition device is an indoor partition device, the geographical coordinates of the partition device are recorded using UWB positioning technology;
[0053] Based on the geographic coordinates of the interval device, a 3D model of the interval device is obtained.
[0054] In this embodiment of the invention, the type of each bay device in a substation is determined.
[0055] 1) If the bay spacer is an outdoor bay spacer, use BeiDou positioning technology to record the coordinates (x1, y1, z1), (x2, y2, z2), (x3, y3, z3), and (x4, y4, z4) of the four vertices of the bottom of the bay spacer projected onto the outer contour of the bay spacer. Let z... min =min(z1,z2,z3,z4). Using 3D modeling technology, when the coordinates of the maintenance personnel (u... i ,v i ,w i The horizontal projection remains at (x1, y1, z) min (x2,y2,z) min (x3,y3,z) min (x4,y4,z) min When the quadrilateral with vertex is the base, it is determined that the maintenance personnel are operating the equipment in that interval, and the range of the quadrilateral is defined as the operating range of the equipment in that interval.
[0056] 2) If the bay is an indoor bay (i.e., an indoor switch cabinet bay), use UWB positioning technology to record the coordinates of the two vertices projected onto the indoor floor from both sides of the front door of the bay. The coordinates of the two vertices projected onto the indoor floor from both sides of the cabinet door. set up Determine the coordinates of the highest point of the indoor ceiling of the equipment room. Using 3D modeling technology, when the coordinates of the maintenance personnel (u... i ,v i ,w i The horizontal projection remains within one meter directly in front of the front cabinet door and When it is determined that maintenance personnel are operating on the equipment in that interval, the range is defined as the operating range of that interval equipment, such as... Figure 2 As shown, Figure 2 This is a top view of the indoor switch cabinet bay provided in an embodiment of the present invention.
[0057] Based on this, the geographical coordinates of all bay equipment in the substation and the geographical coordinates of their operating range are uploaded to the storage module of the monitoring backend to establish a 3D model of the substation bay equipment.
[0058] S20, locate the geographic coordinates of the target object.
[0059] In this embodiment of the invention, the target object is the maintenance personnel. By wearing a Beidou mobile positioning device or a UWB mobile positioning device, the geographical coordinates of the maintenance personnel can be located in real time and uploaded to the monitoring backend through the communication module.
[0060] In the specific implementation process, step S20, "locating the geographic coordinates of the target object," can be performed using the following steps:
[0061] Obtain the positioning signal strength of the BeiDou mobile positioning device and the UWB mobile positioning device worn by the target object;
[0062] If the positioning signal strength of the Beidou mobile positioning device is not less than the corresponding first preset threshold and the positioning signal strength of the UWB mobile positioning device is less than the corresponding second preset threshold, then the target object is determined to be located in an outdoor area, and the geographical coordinates of the target object are located by the Beidou mobile positioning device.
[0063] If the positioning signal strength of the BeiDou mobile positioning device is less than the corresponding first preset threshold and the positioning signal strength of the UWB mobile positioning device is not less than the corresponding second preset threshold, then the target object is determined to be located in an indoor area, and the geographic coordinates of the target object are located by the UWB mobile positioning device.
[0064] In this embodiment of the invention, maintenance personnel locate the target object by wearing both a BeiDou mobile positioning device and a UWB mobile positioning device. The positioning signal strengths of the BeiDou and UWB mobile positioning devices worn by the target object are then obtained respectively.
[0065] If the positioning signal strength of the BeiDou mobile positioning device is not less than its preset threshold (i.e., the first preset threshold), and the positioning signal strength of the UWB mobile positioning device is less than its preset threshold (i.e., the second preset threshold), then it can be determined that the maintenance personnel are in an outdoor area. The system will switch to outdoor positioning mode and use the BeiDou mobile positioning device to locate the geographical coordinates of the maintenance personnel, that is, the real-time BeiDou coordinates of the maintenance personnel. i ,v i ,w i Uploaded to the storage module of the monitoring backend.
[0066] If the positioning signal strength of the BeiDou mobile positioning device is less than its preset threshold (i.e., the first preset threshold), and the positioning signal strength of the UWB mobile positioning device is not less than its preset threshold (i.e., the second preset threshold), then it can be determined that the maintenance personnel are in an indoor area. The system will switch to indoor positioning mode and use the UWB mobile positioning device to locate the geographical coordinates of the maintenance personnel, that is, the real-time UWB positioning coordinates of the maintenance personnel (u... i ,v i ,w i Uploaded to the storage module of the monitoring backend.
[0067] S30, determine the actual interval device where the target object is located based on the geographic coordinates of the target object and the three-dimensional model of each interval device.
[0068] In this embodiment of the invention, for the outdoor bay equipment of the substation, when the coordinates (u) of the maintenance personnel are... i ,v i ,w i The horizontal projection remains at (x1, y1, z) min (x2,y2,z) min (x3,y3,z) min (x4,y4,z) min When the quadrilateral with vertex ) is the base, it is determined that the maintenance personnel are operating on the interval equipment. At this time, the interval equipment can be regarded as the actual interval equipment where the maintenance personnel are located, and the number of the actual interval equipment can be determined.
[0069] For indoor bay equipment in substations, when the coordinates of maintenance personnel... (ui,vi,wi) The horizontal projection remains within one meter directly in front of the front cabinet door, and If it is determined that the maintenance personnel are operating on the equipment in that interval, then that interval can be taken as the actual interval where the maintenance personnel are located, and the number of that actual interval can be determined.
[0070] S40 uses the operation ticket output by the five-proof host and the feedback information from the five-proof key to determine the target interval device that needs to be operated.
[0071] The monitoring backend communicates with the five-proof host. After the operation and maintenance personnel simulate the operation on the five-proof host, they send the operation ticket to the five-proof key and the monitoring backend. The monitoring backend determines the number of the interval device (i.e., the target interval device) that the operation and maintenance personnel should operate based on the content of the operation ticket and the feedback information from the five-proof key. In addition, it can also determine the number of the next interval device (i.e., the next interval device) that the operation and maintenance personnel should go to after the operation is completed.
[0072] S50 determines whether the target object has mistakenly entered a live compartment by comparing the actual compartment equipment with the target compartment equipment.
[0073] In this embodiment of the invention, the monitoring backend compares the number of the actual interval device with the number of the target interval device. If the interval numbers of the two are the same, it is determined that the maintenance personnel have not mistakenly entered the live interval. Conversely, if the interval numbers of the two are different, it is determined that the maintenance personnel have mistakenly entered the live interval.
[0074] Furthermore, if it is determined that the target object has mistakenly entered the energized compartment, the monitoring backend can further output alarm information indicating that the object has mistakenly entered the energized compartment.
[0075] When the monitoring backend determines that maintenance personnel are staying within the operating range of equipment that does not require operation, it sends a "misguided entry" alarm to their mobile positioning device. If the maintenance personnel stay within the operating range of an area where operation is not required for a certain period of time, the "misguided entry" alarm information is also sent to the mobile APP (i.e., mobile application) of the on-site management and supervision personnel. Specifically:
[0076] When the monitoring backend determines that the maintenance personnel have remained within the designated operating interval for more than t hours, it sends an "intrusion alert" to the wearable mobile positioning device. t+Δt At the same time, an alarm message for accidentally entering the wrong interval is sent to the mobile APP of the on-site management and supervision personnel.
[0077] Furthermore, if the operation ticket output by the five-proof host and the feedback information from the five-proof key determine that the target object is in the next interval device after the operation of the target interval device, and if the feedback information from the five-proof key output by the five-proof host confirms that the target object has finished operating the target interval device, the monitoring backend can further output notification information indicating the next interval device. Specifically:
[0078] Once the information transmitted back by the five-proof key indicates that the operation of the interval device has been completed, the monitoring backend sends a voice prompt to the mobile positioning device worn by the maintenance personnel, informing them of the number of the next interval device to be operated. When the maintenance personnel arrive at the operating range of the next interval device, a voice prompt "Target device reached" is sent to the mobile positioning device worn by the maintenance personnel.
[0079] Additionally, when the monitoring backend detects that the operation information transmitted from the maintenance personnel's five-proof key to the five-proof host contains skipped steps, it sends an unlocking operation alarm to the mobile positioning device worn by the maintenance personnel (which can be one or more of a Beidou mobile positioning device and a UWB mobile positioning device), and also sends the unlocking operation alarm information to the mobile APP of the on-site management and supervision personnel. In this regard, embodiments of the present invention may further include the following steps:
[0080] If the feedback information from the five-proof key output by the five-proof host determines that the target object has performed a skip operation, an alarm message indicating the unlocking operation will be output.
[0081] The maintenance personnel's five-proof key enforces control over every step of the operation. If a maintenance personnel wants to skip to the next step without performing the current operation, they need to perform a skip operation on the five-proof key. The five-proof key will send the skip operation information back to the five-proof host. When the monitoring backend detects that the maintenance personnel have skipped steps based on the information sent back by the five-proof key, it determines that the maintenance personnel have performed an unlocking operation. It then sends an unlocking operation alarm to the mobile positioning device worn by the maintenance personnel (which can be one or more of Beidou mobile positioning devices and UWB mobile positioning devices) and sends the unlocking operation alarm information to the mobile APP of the on-site management and supervision personnel.
[0082] The substation switching operation monitoring method provided in this invention uses BeiDou positioning, UWB positioning, and 3D modeling technology to monitor in real time whether maintenance personnel accidentally enter energized compartments and to supervise whether they use the five-proof key as required. Compared with existing technical solutions, this invention has the following significant advantages:
[0083] (1) It can monitor in real time whether maintenance personnel accidentally enter the energized compartment and whether there is any step-by-step unlocking operation. It is of great practical significance for standardizing the behavior of operation personnel and ensuring the personal safety of substation maintenance personnel and the safety of equipment and power grid.
[0084] (2) The system collects the real-time location of all maintenance personnel and issues an alarm when someone accidentally enters a live compartment or skips steps during operation. The system also uploads the personnel information and alarm information to the mobile APP of the on-site management and supervision personnel. This enables real-time monitoring and alarming of switching operations by maintenance personnel, effectively preventing accidental entry into live compartments and misoperation.
[0085] (3) By using UWB 3D positioning technology, the system can automatically distinguish which floor of the building the maintenance personnel are working on, thus avoiding the problem of incorrect positioning of the operating range when there are switch cabinets on both the upper and lower floors of the building.
[0086] (4) For the coordinate data of each bay equipment in the substation, only one measurement is needed using BeiDou positioning technology and UWB positioning technology, and the coordinates of each bay equipment in the substation are stored in the monitoring backend storage module. In fact, there is no need to install BeiDou or UWB positioning equipment on the substation equipment, which saves costs.
