It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The gateway-based electric power personnel positioning method can be applied to the application environment shown in fig. 1. The monitoring terminal 101 communicates with the gateway device 102 through a network, and the gateway device 102 may communicate with the positioning terminal 104 through the positioning base station 103. When a monitoring user needs to monitor the position information of the electric power personnel of the transformer substation, a positioning request can be triggered to the gateway device 102 through the monitoring terminal 101, after the gateway device 102 receives the request, first position information acquired by the positioning terminal 104 can be obtained, the first position information can be obtained through a low-precision GPS base station, after an electric power area where the electric power personnel are located is determined, a corresponding high-precision positioning mode is selected through the electric power area, and second position information of the electric power personnel is obtained from the high-precision positioning base station 103. The monitoring terminal 101 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, the gateway device 102 may be an intelligent gateway with edge computing capability, the positioning base station 103 may be various base stations for positioning personnel, including a GPS base station, and base stations that need to be used in various high-precision positioning manners, such as a beidou satellite base station or a UWB base station, and the positioning terminal 104 may be various devices that can acquire position information of electric personnel, such as an intelligent bracelet or a safety helmet worn by the electric personnel.
In one embodiment, as shown in fig. 2, a gateway-based electric power personnel location method is provided, which is described by taking the method as an example applied to the gateway device 102 in fig. 1, and includes the following steps:
in step S201, the gateway device 102 determines, in response to a positioning request for power personnel of the substation triggered by the monitoring terminal 101, a power personnel to be positioned corresponding to the positioning request.
The positioning request is triggered from the monitoring terminal 101 to the gateway device 102, and is used for positioning the power personnel in the substation, and the power personnel to be positioned is the power personnel needing to obtain the position information in the positioning request. When a monitoring user needs to locate an electric power person in a certain transformer substation, a location request can be triggered to the gateway device 102 through the monitoring terminal 101, and then the gateway device 102 can respond to the location request triggered by the monitoring terminal 101, and the electric power person, of which the monitoring user needs to acquire location information, is determined from a plurality of electric power persons in the transformer substation and serves as the electric power person to be located.
Step S202, the gateway device 102 determines the positioning terminal 104 of the power person to be positioned, and receives the first position information of the power person to be positioned, which is acquired by the positioning terminal 104.
The positioning terminal is a terminal device for acquiring first position information of the power person to be positioned, and the first position information corresponds to the power person to be positioned one by one, and the first position information may be position information of the power person to be positioned acquired by the positioning terminal 104 through a positioning mode with relatively low positioning accuracy, such as GPS positioning. Specifically, the positioning terminal 104 may obtain the first location information of the power person to be positioned in real time through a low-precision positioning manner such as GPS positioning, and when the gateway device 102 receives a positioning request of the power person to be positioned, the first location information of the power person to be positioned, which is acquired by the positioning terminal 104, may be obtained directly from the positioning terminal 104 of the power person to be positioned, or may be obtained through the low-precision positioning base station 103 in communication with the positioning terminal 104, that is, the GPS base station in communication with the positioning terminal 104.
Step S203, the gateway device 102 acquires the power region where the power person to be located is located according to the first location information.
The power region where the power person to be positioned is located refers to the current power region, in the transformer substation, the power region may be composed of a plurality of power regions, and after the gateway device 102 obtains the first position information of the power person to be positioned, it may be preliminarily determined which power region of the transformer substation the power person to be positioned is located in according to the first position information of the power person, so as to obtain the current power region where the power person to be positioned is located.
Step S204, the gateway device 102 determines a positioning mode for the electric power personnel to be positioned according to the electric power region, and obtains second position information of the electric power personnel to be positioned by using the positioning mode; the second position information has a positioning accuracy greater than the first position information.
The positioning method is a preset positioning method for acquiring high-precision second position information, and different positioning methods may need to be adopted to acquire the second position information due to different power areas where power personnel to be positioned are located, for example, for high-precision satellite positioning, the positioning method is only suitable for being performed in an outdoor area with good satellite signals, and for an indoor area, other high-precision positioning methods need to be adopted to acquire the second position information. Specifically, after obtaining the power region of the power person to be positioned, the gateway device 102 needs to select an appropriate high-precision positioning method based on the power region to obtain the high-precision second position information of the power person to be positioned.
In step S205, the gateway device 102 returns the second location information to the monitoring terminal for displaying.
Finally, after obtaining the second high-precision position information of the power person to be positioned, the gateway device 102 may also return the second position information to the monitoring terminal 101 of the monitoring person for display, for example, a pre-constructed virtual map for the substation may be displayed on the display device of the monitoring terminal 101, and the second position information of the power person to be positioned may be displayed in the virtual map.
In the gateway-based electric power personnel positioning method, the gateway device 102 responds to a positioning request, triggered by the monitoring terminal 101, for electric power personnel in the transformer substation, and determines electric power personnel to be positioned corresponding to the positioning request; determining a positioning terminal 104 of the electric power personnel to be positioned, and receiving first position information of the electric power personnel to be positioned, which is acquired by the positioning terminal 104; acquiring an electric power region where an electric power person to be positioned is located according to the first position information; determining a positioning mode aiming at the power personnel to be positioned according to the power region, and obtaining second position information of the power personnel to be positioned by using the positioning mode; the positioning precision of the second position information is greater than that of the first position information; and returning the second position information to the monitoring terminal 101 for display. According to the method and the device, the gateway equipment 102 is used for responding to the positioning request of the electric power personnel of the transformer substation, the low-precision first position information of the electric power personnel to be positioned is obtained, after the electric power region is determined, the high-precision second position information of the electric power personnel to be positioned is obtained and is returned to the monitoring terminal 101 for displaying, the high-precision positioning analysis mode can be used for obtaining the second position information only when the monitoring terminal 101 requests the electric power personnel to be positioned, therefore, the calculation loss is reduced under the condition that the positioning precision is guaranteed, and the resource utilization rate is improved.
In one embodiment, step S203 may further include: the gateway device 102 acquires a region type corresponding to the power region; and determining a positioning mode aiming at the power personnel to be positioned according to the region type.
The area type refers to the area type of the power area where the power person to be positioned is located, and in this embodiment, the determination of the positioning manner of the power person to be positioned is mainly determined based on the area type of the power area where the power person to be positioned is located. For example the power domain of a substation may consist of power domain a, power domain B and power domain C, wherein power domain A and power domain C are of domain type A, and power domain B can be of domain type B, if the positioning mode A can be adopted to acquire the second position information of the power personnel to be positioned for the area type A, and the positioning mode B can be adopted to acquire the second position information of the power personnel to be positioned for the area type B, when the power area where the power personnel to be positioned is currently located is the power area A or the power area C, gateway device 102 may then determine that the location mode for the power person to be located is location mode a, if the power region in which the power person to be positioned is currently located is the power region B, the gateway device 102 may determine that the positioning manner for the power person to be positioned is the positioning manner B.
Further, the region types include: outdoor type and indoor type; the positioning mode comprises the following steps: a Beidou satellite positioning mode and a UWB base station positioning mode; the gateway device 102 determines a positioning manner for the power personnel to be positioned according to the area type, and may further include: if the area type is the outdoor type, the gateway device 102 determines that the positioning mode is the Beidou satellite positioning mode; and if the area type is the indoor type, determining that the positioning mode is the UWB base station positioning mode.
In this embodiment, the regional type can include outdoor type and indoor type two kinds, promptly in this embodiment, the electric power region in the transformer substation can be divided into indoor region and outdoor region two kinds, and the location mode of high accuracy then can be divided into carries out the big dipper satellite location mode of fixing a position through the big dipper satellite to and carry out the UWB basic station location mode two kinds of fixing a position through setting up UWB basic station in the transformer substation. Specifically, if the area type of the power area where the power person to be positioned is currently located is an outdoor type, that is, the power person to be positioned is currently located in an outdoor area of the substation, the gateway device 102 may determine to use a Beidou satellite positioning mode to achieve acquisition of the second position information of the power person to be positioned, and if the area type of the power area where the power person to be positioned is currently located is an indoor type, that is, the power person to be positioned is currently located in an indoor area of the substation, acquisition of the second position information may be achieved through a UWB base station positioning mode, so that the problem that the high-precision position information of the power person to be positioned cannot be obtained through a satellite positioning mode due to weak indoor area satellite signals can be solved.
Further, in an embodiment, as shown in fig. 3, in the case that the positioning mode is a beidou satellite positioning mode, the step S204 may further include:
step S301, the gateway device 102 obtains preset position coordinates of at least four Beidou satellites from a preset Beidou satellite base station, and distances between the at least four Beidou satellites and the positioning terminal 104.
In this embodiment, if the power person to be positioned is currently located in an outdoor area of the transformer substation, the gateway device 102 may obtain the second position information of the power person to be positioned in a Beidou satellite positioning manner. The Beidou satellite positioning method comprises the step of obtaining second position information of an electric power person to be positioned through a space surveying and mapping intersection principle, wherein the second position information of the electric power person to be positioned can be obtained through the space surveying and mapping intersection principle, the principle refers to positions of four satellite reference points which are obtained in advance, and distances between the four satellites and the positioning terminal 104, and therefore the position of the positioning terminal 104 can be determined. Particularly, can preset be used for realizing the outdoor regional big dipper satellite basic station of transformer substation and fix a position as positioning base station 103, can preset the position coordinate that has four at least big dipper satellites in this big dipper satellite basic station, when gateway equipment 102 need go to acquire the second positional information of the electric power personnel of undetermining through big dipper satellite positioning mode, can be through establishing the communication connection with big dipper satellite basic station, big dipper satellite basic station then can communicate with positioning terminal 104, gather the distance between positioning terminal 104 and the above-mentioned four big dipper satellites, and with the position coordinate of four big dipper satellites, and return to gateway equipment 102 the distance between positioning terminal 104 and four big dipper satellites.
Step S302, the gateway device 102 obtains second position information according to the position coordinates of the at least four Beidou satellites and the distances between the at least four Beidou satellites and the positioning terminal 104.
After obtaining the position coordinates of the four Beidou satellites and the distances between the four Beidou satellites and the positioning terminal 104, the gateway device 102 may obtain second position information based on the position coordinates and the distances.
The second position information may be specifically calculated by the following formula:
where ρ is1、ρ2、ρ3And ρ4Respectively, the distances between the first satellite, the second satellite, the third satellite and the fourth satellite and the positioning terminal 104, and the position coordinate of the first satellite is (x)1,y1,z1) The position coordinate of the second satellite is (x)2,y2,z2) The position coordinate of the third satellite is (x)3,y3,z3) The position coordinate of the fourth satellite is (x)4,y4,z4) And c represents the propagation velocity of electromagnetic waves, tuThen the time difference between the satellite and the positioning terminal 104 is represented and the second position information may be represented by (x)u,yu,zu) And (4) showing. In the above calculation formula, the time difference t between the satellite and the positioning terminal 104 is determineduUnknown, therefore in order to calculate the second position information (x)u,yu,zu) Then x can be obtained by constructing the above four formulasu,yu,zu,tuRespectively as four unknowns, and the second position information (x) can be obtainedu,yu,zu)。
In addition, in an embodiment, as shown in fig. 4, when the positioning manner is a UWB base station positioning manner, step S204 may further include:
step S401, the gateway device 102 acquires a target UWB base station corresponding to the electric power area from a plurality of UWB base stations set by the transformer substation; wherein, the detection area range of the target UWB base station is adapted to the power area.
If the power person to be positioned is currently located in the indoor area of the transformer substation, the gateway device 102 may obtain the second position information of the power person to be positioned in a UWB base station positioning manner. Because the indoor area of transformer substation can be a plurality of, consequently can set up a plurality of UWB basic stations that correspond to different detection zone scopes, be used for detecting different indoor areas respectively, and the target UWB basic station is the UWB basic station that is used for detecting the electric power region of locating of the electric power personnel of awaiting positioning. Specifically, when the gateway device 102 determines that the second position information of the power person to be located is obtained by means of UWB base station location, a UWB base station whose detection area range is adapted to the power area may be determined from the plurality of UWB base stations as a target UWB base station.
For example, the UWB base stations set in the substation in advance may include the UWB base station A, UWB base station B and the UWB base station C, where the UWB base station a is used to detect the indoor area A, UWB base station B is used to detect the indoor area B, and the UWB base station C is used to detect the indoor area C, and then when the power person to be located is in the indoor area C, the gateway device 102 may use the UWB base station C as the target UWB base station.
In step S402, the gateway device 102 acquires, from the target UWB base station, the position information, which is acquired by the target UWB base station and is specific to the electric power person to be positioned, as second position information.
Then, the gateway device 102 may obtain, from the target UWB base station, the position information, which is acquired by the target UWB base station and is specific to the electric power person to be located, as second position information. The gateway device 102 may use the target UWB base station as the positioning base station 103, and by establishing a communication connection between the gateway device 102 and the target UWB base station, the target UWB base station collects the position information of the positioning terminal 104 located in the indoor area, and returns the position information to the gateway device 102 as the position information of the electric power person to be positioned, and the gateway device 102 may use the position information of the electric power person to be positioned, which is returned by the target UWB base station, as the high-precision position information of the electric power person to be positioned, that is, the second position information.
In the above embodiment, the gateway device 102 may determine the adopted positioning manner according to the area type of the area where the electric power person to be positioned is located, if the electric power person to be positioned is of the outdoor type, the positioning is realized by adopting a Beidou satellite positioning manner, if the electric power person to be positioned is of the indoor type, the positioning is realized by adopting a UWB base station positioning manner, wherein the Beidou satellite positioning is realized by the position coordinates of at least four Beidou satellites and the distances between the four Beidou satellites and the positioning terminal 104, and the UWB base station positioning is realized by determining the target UWB base station and returning corresponding positioning information from the target UWB base station, so that the positioning accuracy can be improved, and the applicability of the high-accuracy positioning method can be improved.
In one embodiment, as shown in fig. 5, step S203 may further include:
in step S501, the gateway device 102 acquires a plurality of preset power areas for the substation and acquires area coordinate sections corresponding to the plurality of power areas.
In this embodiment, the substation may be composed of a plurality of power areas, and different power areas may respectively correspond to different area coordinate spaces for representing area ranges of the power areas. For example, in a substation, power area a corresponds to area coordinate interval a, power area B corresponds to area coordinate interval B, and power area C corresponds to area coordinate interval C. The gateway device may be configured to store area coordinate sections corresponding to a plurality of power areas of the substation in advance, and when it is necessary to determine a power area in which a power person to be located is located, the gateway device may obtain the area coordinate sections corresponding to the power areas.
Step S502, the gateway device 102 acquires a target area coordinate interval matched with the first position information from the area coordinate intervals, and uses an electric power area corresponding to the target area coordinate interval as an electric power area where the electric power person to be positioned is located.
Then, the gateway device 102 may find a target area coordinate interval matching the first location information from a plurality of area coordinate intervals corresponding to each power area, or may determine, as the target area coordinate interval, an area coordinate interval including the first location information in a plurality of area coordinate spaces.

Step S602, the gateway device 102 returns the electric power personnel information list to the monitoring terminal 101 for display;
step S603, the gateway device 102 acquires target power staff information selected by the monitoring terminal 101 from the displayed power staff information list, and takes a power staff corresponding to the target power staff information as a power staff to be positioned.

In an embodiment, an electric power personnel positioning method based on a gateway is further provided, that is, rough position information of an electric power personnel is obtained through the gateway, an area range where the electric power personnel is located is determined according to the rough position information, an area type corresponding to the area range is determined, namely the electric power personnel belongs to an indoor area or an outdoor area of a transformer substation, if the electric power personnel belongs to the outdoor area, the accurate position of the electric power personnel is obtained through a Beidou high-precision positioning function, and if the electric power personnel belongs to the indoor area, the accurate position of the electric power personnel is obtained through a positioning function of a UWB base station arranged in the area. The method specifically comprises the following steps:
(1) and responding to a positioning request sent by the user terminal, and determining the power personnel to be positioned corresponding to the positioning request.
The power personnel to be positioned refers to the power personnel needing to acquire the position information, and may be, for example, power operation personnel needing to perform position supervision. The user terminal may be a user terminal of a power supervisor who supervises a power operator. When the electric power supervision personnel need to carry out position supervision on some electric power operation personnel, a positioning request can be initiated to the intelligent gateway through the user terminal, and then the intelligent gateway can respond to the request and simultaneously determine the electric power operation personnel needing to be supervised by the electric power supervision personnel as the electric power personnel to be positioned.
For example, when the user terminal triggers a positioning request to the intelligent gateway, the intelligent gateway can return a personnel list carrying information of power operation personnel, the personnel list is returned to the user terminal for display, the supervisor can select the displayed personnel list, and the selected personnel is used as the power personnel to be positioned, so that the intelligent gateway can determine the power personnel to be positioned.
(2) And determining a positioning terminal corresponding to the electric power personnel to be positioned, and receiving rough position information acquired by the positioning terminal.
The positioning terminal refers to a terminal device used for collecting rough position data of an electric power worker to be positioned, the terminal device corresponds to the electric power worker one by one, for example, the positioning terminal can be a wearable device of the electric power worker, such as a safety helmet and an intelligent bracelet, and the device can obtain position information of the electric power worker in a GPS positioning mode. Then, the intelligent gateway may obtain the location information acquired by the positioning terminal, for example, the location information may be obtained by communicating with a GPS base station storing the location information, or the location information may be returned by the positioning terminal as rough location information by directly communicating with the positioning terminal.
(3) And determining the type of the area where the power personnel to be positioned is located according to the rough position information.
The area type may include an outdoor type and an indoor type, the intelligent gateway may divide the substation into a plurality of areas in advance, and after obtaining the area location information, it may determine a substation area corresponding to the location, and the area type of the area, that is, whether the area belongs to the indoor area or the outdoor area.
(4) And determining a high-precision positioning mode corresponding to the area type, and acquiring accurate position information aiming at the electric power personnel to be positioned by utilizing the corresponding high-precision positioning mode.
The high-precision positioning mode can comprise high-precision positioning realized by a satellite positioning mode and high-precision positioning realized by a UWB base station, when the area belongs to an indoor area, high-precision position information acquisition is realized by the UWB base station, and if the area belongs to an outdoor area, high-precision position information acquisition is realized by the satellite positioning mode.
If the indoor area is the indoor area, the target UWB base station corresponding to the indoor area needs to be determined in the plurality of UWB base stations, for example, the intelligent gateway may first acquire a detection area corresponding to each UWB base station, use the UWB base station whose detection area is the indoor area as the target UWB base station, and acquire the position information of the power person to be positioned, which is acquired by the target UWB base station, as the accurate position information of the power person.
If the intelligent gateway is an outdoor area, the intelligent gateway needs to acquire the preset position coordinates of 4 Beidou satellites from the Beidou base station and the distance between the 4 Beidou satellites and the positioning terminal, so that the accurate position information of the positioning terminal is calculated and obtained and is used as the accurate position information of the power personnel.
(5) And after the accurate position information is obtained, returning the accurate positioning information to the user terminal of the monitoring personnel for displaying.
For example, the precise location information may be displayed in a virtual map of a pre-constructed substation area.
