To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
A first embodiment of the present application relates to a ground rod management method, a flow of which is shown in fig. 1, and the method includes the following steps:
in step 101, before the server maintenance work is started, the position data of the high-voltage line in the work area is determined, and the electronic fence corresponding to the work area in the work area is set based on the position data of the high-voltage line.
In one embodiment, the location data of the high voltage lines of the work section includes latitude and longitude data. In this embodiment, the working area is determined from longitude and latitude data of the high voltage wires of the working section, and the electronic fence is a two-dimensional planar electronic fence.
In another embodiment, the location data of the high voltage lines of the work section includes latitude and longitude data and elevation data. In this embodiment, the working area is determined from the longitude and latitude data and the elevation data of the high voltage line of the work section, the working area includes a non-hitched area and a hitched area, and the electronic fence is a three-dimensional stereo electronic fence including a first fence portion corresponding to the non-hitched area and a second fence portion corresponding to the hitched area.
Wherein, the two parts of the three-dimensional electronic fence can be arranged in various ways. Fig. 3 illustrates an embodiment of a three-dimensional electronic fence, wherein a first fence portion corresponds to a ground area and a second fence portion corresponds to a hitch area. Fig. 4 shows another embodiment of a three-dimensional electronic fence, wherein a first fence portion corresponds to a non-hitched area including a ground area and a second fence portion corresponds to a hitched area. And is not limited to these two embodiments.
Optionally, the step 101 may further include the following steps (1) (2):
in the step (1), a geographic information platform comprising high-voltage line position layers of all sections in a preset area is deployed in a server in advance; and (3) then, executing the step (2), wherein the server determines a working section of the high-voltage wire before the maintenance operation is started, selects the high-voltage wire position layer object of the working section in the geographic information platform, extends according to the position data of the high-voltage wire, and automatically generates the electronic fence.
The geographic information platform is used for storing, realizing and calculating position and attribute data related to the power transmission line, the power equipment and the like to obtain position map layers of all sections of the high-voltage line in a preset area.
The preset area can be set according to the deployment condition of the server; taking china as an example, if only one server is deployed in china, the preset area is all high-voltage transmission line areas in the country; assuming that a server is deployed in each geographical large area in China, the preset area is all high-voltage transmission line areas of the geographical large area; and so on.
Optionally, the step (2) "extending according to the position data of the high-voltage line, and automatically generating the electronic fence" may further be implemented as follows: the high-voltage line is extended at two sides of the horizontal projection by a proper amount, and the extension distance can be set to a preset length at two sides of the horizontal projection, such as but not limited to 10 meters, 20 meters, and the like. For example, fig. 2 is a schematic diagram of an example automatically generated fence area extending 20 meters across a horizontal projection of an example high voltage line work section.
Optionally, before the maintenance operation, a certain maintenance operator can be designated to use and recover the grounding rod according to the dispatch list, and the maintenance operator carries the grounding rod and the mobile terminal corresponding to the maintenance operation to the operation site.
Alternatively, the implementation server may be operated by a relevant person to associate the ground rod with the mobile terminal before the maintenance work is started. Optionally, before the maintenance operation is started, if the grounding rod and the mobile terminal are not associated in advance, when the grounding rod and the mobile terminal are detected to be present in the electronic fence at the same time, the server automatically associates the grounding rod and the mobile terminal, and sends the position data of the grounding rod to the mobile terminal.
Optionally, the server and the mobile terminal, and the mobile terminal and the ground rod respectively adopt a cellular network, such as GPRS, CDMA, 3G, TLE, 4G, and the like. It can be understood that the manner in which the server acquires the information from the mobile terminal may be a manner in which the mobile terminal pushes the information, or a manner in which the server actively queries the mobile terminal.
Alternatively, the geographic information platform may be deployed in both the server and the mobile terminal, and the process of automatically generating the electronic fence area is implemented by the service operator operating (for example, by operating an input unit such as a keyboard or a mouse) on the mobile terminal side and synchronizing to the server.
Thereafter, step 102 is entered, and the server obtains position data of the grounding rod during the maintenance operation, wherein the grounding rod comprises the first positioning unit.
It should be noted that, during the maintenance work, the ground rod is in an open state. For example, a service worker responsible for recovering the grounding rod may be assigned to open the grounding rod before or after arriving at the service site. When the server detects that the grounding bar is opened, it may be set to enter a period of maintenance work.
Optionally, the server communicates with the ground rod via a cellular network, such as GPRS, CDMA, 3G, TLE, 4G, etc. It can be understood that the manner in which the server obtains the information from the ground rod may be a manner in which the ground rod is pushed, or may be a manner in which the server actively queries the ground rod.
Optionally, the first positioning unit is a GNSS positioning module. Specifically, the GNSS positioning module tracks GNSS satellites, requests differential correction data from one reference station or a plurality of reference station networks (CORS) through a cellular network, understands the differential correction data through a real-time carrier-phase differential algorithm (RTK), and calculates high-precision position data of the ground rod, and uses a GNSS native satellite positioning result if the reference station or the CORS is unavailable or no cellular network exists.
Then, step 103 is executed, in which the server compares the position data of the grounding rod with the electronic fence to determine whether the grounding rod is in the electronic fence.
Optionally, the server may compare the position data of the grounding rod with the electronic fence periodically or in real time until determining that the grounding rod is in the electronic fence.
Optionally, the position data of the ground rod includes longitude and latitude data. In one embodiment, this step 103 is further implemented as: and the server compares the longitude and latitude data of the grounding rod with the two-dimensional plane electronic fence to judge whether the grounding rod is in the electronic fence.
Optionally, the position data of the ground rod includes longitude and latitude data and elevation data.
In one embodiment, this step 103 is further implemented as: the server compares the longitude and latitude data of the grounding rod with the two-dimensional plane electronic fence to judge whether the grounding rod is in the two-dimensional plane electronic fence or not; if the grounding rod is in the two-dimensional plane electronic fence, the server compares the elevation data of the high-voltage wire of the operation section with the elevation data of the grounding rod, and judges whether the grounding rod is on the high-voltage wire of the operation section or on the ground of the working area; and if the difference between the elevations of the two is smaller than a preset threshold, for example, the threshold is selected to be 5 meters, or the height of the two can be set to be sub-meter level, centimeter level, meter level and the like according to the positioning precision, determining that the grounding rod is on the high-voltage line of the operation section, and if the difference between the elevations of the two is larger than the preset threshold, determining that the grounding rod is on the ground of the working area.
In another embodiment, this step 103 is further implemented as: the longitude and latitude data and the elevation data of the grounding rod are compared with a first fence part of the three-dimensional electronic fence by the server, and whether the grounding rod is in the non-hanging area or not is judged; comparing the longitude and latitude data and the elevation data of the grounding rod with a second fence part of the three-dimensional electronic fence to judge whether the grounding rod is in the hanging area; and if the grounding rod is judged to be in the non-hanging area, determining that the grounding rod is on the ground of the working area, and if the grounding rod is judged to be in the hanging area, determining that the grounding rod is on a high-voltage line of the working section.
And then, entering step 104, and after the maintenance operation is finished, if the grounding rod is still in the electronic fence, sending a missing alarm signal to a background server and/or a mobile terminal corresponding to the maintenance operation.
The background server corresponding to the maintenance operation is far away from the operation site, and the mobile terminal corresponding to the maintenance operation can be on the operation site or leave the operation site following the site operator. In one embodiment, the miss alert is sent to the backend server and the service operator returns to the backend server to know the miss. In another embodiment, the legacy alert signal is sent to the mobile terminal, either directly to the mobile terminal or first to a background server, and then the mobile terminal is notified by some means (such as short message, etc.) from the background. In yet another embodiment, the missed alert signal is sent to the background server and the mobile terminal simultaneously.
In one embodiment, the miss alert signal is sent to a mobile terminal corresponding to the overhaul job, the mobile terminal further comprising a second location unit. In the embodiment, the server periodically acquires the position data of the mobile terminal, judges whether the mobile terminal is in the electronic fence or not, and determines that the maintenance work is finished when all the grounding rods and the mobile terminal are judged to be away from the electronic fence during the maintenance work.
Optionally, the second positioning unit is a GNSS positioning module. Specifically, the GNSS positioning module tracks GNSS satellites, requests differential correction data from one reference station or a plurality of reference station networks (CORS) through a cellular network, understands the differential correction data through a real-time carrier-phase differential (RTK) algorithm, and calculates high-precision position data of the ground rod, and uses GNSS native satellite positioning results if the reference station or the CORS is unavailable or no cellular network exists.
Optionally, the step 104 may be further implemented as: after the overhaul operation is finished, if the server detects that the grounding rod is still on the high-voltage line of the operation section, sending a first omission warning signal representing a first emergency degree to a background server and/or a mobile terminal corresponding to the overhaul operation so as to recover the grounding rod; and if the grounding rod is still on the ground of the working area, sending a second omission warning signal representing a second emergency degree to a background server and/or a mobile terminal corresponding to the maintenance operation so as to recover the grounding rod, wherein the first emergency degree is greater than the second emergency degree.
In one embodiment, after the maintenance operation is finished, if the server detects that the grounding rod is still on the high-voltage line of the operation section, whether the grounding rod is missed on the high-voltage line of the operation section is judged again further according to voltage and/or current information of a line related to the high-voltage line of the operation section in a management system of an electric power system to which the high-voltage line belongs, and if the grounding rod is judged again to be on the high-voltage line of the operation section, a first missing alarm signal is sent to a background server and/or a mobile terminal corresponding to the maintenance operation to recover the grounding rod.
