Description

Technical Field

[0001] This application belongs to the field of carrier communication positioning technology, and particularly relates to a carrier network positioning method, device, energy meter, electronic device and medium. Background Technology

[0002] As core equipment for monitoring power grid operation parameters and measuring user electricity consumption, electricity meters have been installed on a massive scale. These devices are widely distributed in various scenarios such as urban buildings, old residential areas, industrial parks, and rural courtyards, forming the basic network for power metering and operation and maintenance management. In the full life cycle management of the power system, the installation verification, fault repair, periodic calibration, and line loss investigation of electricity meters all rely on accurate on-site positioning capabilities. However, the current situation where most mainstream electricity meters do not integrate independent positioning modules has become a core bottleneck restricting the improvement of operation and maintenance efficiency.

[0003] The current method of locating electricity meters relies on the traditional "manual recording - system entry" model, whose core flaw lies in the difficulty of guaranteeing the accuracy and timeliness of the location information. During installation, meters for a localized power supply area are typically installed in multi-meter boxes, with hundreds of meters in a single area. Installers must maintain paper records of the correspondence between the meter boxes and the meters before manually entering the data into the backend management system. This process is prone to errors in paper records and system entry, easily leading to a disconnect between the actual installation location of the meters and the information in the management system, resulting in "location-disconnected" meters. In older residential areas and suburban areas with non-standard wiring, problems such as unclear meter box markings and chaotic wiring routes further exacerbate the risk of information mismatch, leaving many meters in a state of "numbered in the system, but no location on site." Summary of the Invention

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a carrier network positioning method, apparatus, electricity meter, electronic device, and medium to improve positioning accuracy.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0052] The carrier network positioning method, device, electricity meter, electronic device and medium provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0053] Among them, the carrier network positioning method can be applied to the terminal, and can be executed by the hardware or software in the terminal.

[0054] The terminal includes, but is not limited to, portable communication devices such as mobile phones or tablets with touch-sensitive surfaces (e.g., touchscreen displays and / or touchpads). It should also be understood that, in some embodiments, the terminal may not be a portable communication device, but rather a desktop computer with touch-sensitive surfaces (e.g., touchscreen displays and / or touchpads).

[0055] The following embodiments describe a terminal including a display and a touch-sensitive surface. However, it should be understood that the terminal may include one or more other physical user interface devices such as a physical keyboard, mouse, and joystick.

[0056] The carrier network positioning method provided in this application embodiment can be executed by an electronic device or a functional module or entity in an electronic device that can implement the carrier network positioning method. The electronic devices mentioned in this application embodiment include, but are not limited to, electricity meters, smart water meters, gas meters, smart switches, inverters, sensors, robots, smart streetlights, etc. The carrier network positioning method provided in this application embodiment is described below using an electronic device as the execution subject.

[0057] like Figure 1As shown, the carrier network positioning method includes steps 110, 120 and 130.

[0058] Step 110: In response to the positioning command issued by the carrier module of the object to be located, the star-flash module of the object to be located scans the star-flash network to identify multiple target objects with positioning information.

[0059] In this embodiment, the carrier network is an Internet of Things (IoT) communication network built based on carrier communication technology, used to realize the interconnection of various objects within the network, command transmission, and data interaction. The carrier network is compatible with mainstream carrier communication forms such as low-voltage power line carrier and radio frequency carrier, and can be flexibly deployed in different scenarios such as power IoT, smart homes, industrial IoT, and municipal facilities.

[0060] In this embodiment, the carrier network includes multiple objects, each integrating a carrier module and a strobe module. These objects access the carrier network through the carrier module and the strobe network through the strobe module.

[0061] Depending on the application scenario, the objects can be of different types. For example, in the power Internet of Things (IoT) scenario, objects can be electricity meters, smart water meters, smart gas meters, smart heat meters, distribution terminals, data collectors, concentrators, fault indicators, photovoltaic grid-connected inverters, charging pile metering terminals, etc. In the smart home scenario, objects can be smart wall switches, smart sockets, smart curtain motors, smart thermostats, gas alarms, water leakage sensors, smart door locks, IoT home appliances, etc. In the industrial IoT scenario, objects can be industrial temperature and humidity sensors, pressure sensors, liquid level sensors, controllers, frequency converters, handling robots, industrial inspection robots, etc. In the municipal infrastructure scenario, objects can be smart streetlights, landscape lights, manhole cover sensors, municipal pipeline monitoring terminals, outdoor AC charging piles, battery swapping cabinets, etc. Of course, objects can also be other types of objects, and this application embodiment does not limit this.

[0062] The carrier module is a hardware device whose transmitting end uses signal modulation technology to modulate the data signal into a high-frequency signal and superimpose it onto the power line, allowing the data signal to propagate in the power line network along with low-frequency AC power. Its receiving end uses filtering technology to extract the corresponding high-frequency signal from the power line and demodulates it to obtain the original data signal. Thus, data communication can be achieved through existing power lines.

[0063] A StarScan module is a communication device based on StarScan short-range wireless communication technology. It integrates StarScan communication protocols, radio frequency circuits, and antennas, offering advantages such as strong anti-interference capabilities, high synchronization accuracy, and high connection capacity, making it suitable for complex installation environments. A StarScan network is a wireless ad-hoc network formed within a certain distance by multiple devices equipped with StarScan modules, based on the StarScan communication protocol. In this embodiment, the StarScan network is a network formed by StarScan modules of various objects in a carrier network based on the StarScan communication protocol.

[0064] In this embodiment, the StarScan module and the carrier module are integrated together in the object. After the carrier module is powered on, it powers on the StarScan module and scans the StarScan network according to the internally integrated StarScan communication protocol. During the scanning process, the StarScan module can tune the wireless receiver to a specific communication frequency band and listen to the broadcast information in the StarScan network, extracting location information from the broadcast information to identify multiple target objects with location information.

[0065] The object's location information describes its physical location and can be a two-dimensional coordinate system. The location data of several target objects can be determined manually and uploaded to a backend positioning system. This backend positioning system is then connected to the StarScan module, which periodically broadcasts the known object location information within the current area. This allows each object to be located to scan the StarScan network to identify multiple target objects with location information, thus enabling positioning.

[0066] Step 120: Establish connections with at least three target objects and perform star-flash ranging to obtain the ranging information between the object to be located and each target object.

[0067] In this embodiment of the application, for each target object, the object to be located can broadcast a paging message containing its own ID, the target object ID, etc. in the StarScan communication protocol in the StarScan network. After receiving the paging message with itself as the target, the target object sends a response message. The two parties negotiate and complete the specific settings of communication parameters, resource allocation, etc., thereby establishing a connection.

[0068] After the object U to be located establishes a connection with the target object A, star-flash ranging is performed to obtain the ranging information between U and A. This ranging information can include the identification information of both parties and a physical distance value, such as {U, A, d1}, where d1 is the physical distance between U and A.

[0069] The physical distance between an object U to be located and a target object A can be measured using the time-of-flight method. For example, target object A sends a specific ranging signal to object U, and records the sending time t1. After receiving the ranging signal, object U immediately replies with an acknowledgment signal. After receiving the acknowledgment signal, target object A records the receiving time t2, and calculates the physical distance d between U and A using the formula d = c * (t2 - t1 - delay) / 2, where c is the speed of light and delay is the time delay during the ranging process. This process is repeated multiple times, and the average value d1 of the obtained d is taken as the ranging result between U and A. Of course, ranging can also be performed using methods such as the phase difference method; this embodiment does not limit this approach.

[0070] Similarly, the object to be located can sequentially establish connections with other target objects B, C, D, ... and perform star-flash ranging to obtain the ranging information between the object to be located and each target object.

[0071] Step 130: Calculate the positioning information of the object to be located based on the positioning information and ranging information of each target object.

[0072] The object to be located acquires the location information of multiple target objects through a star-flash network scan, establishes connections with each target object, and performs star-flash ranging to obtain the ranging information with each target object. For example, the location of the target object U is obtained as follows: The physical distance from A is The location of target object B is The physical distance from B is The location of target object C is The physical distance from C is .

[0073] The physical position (x, y) of the object U to be located can be calculated using the polygonal positioning method. For example, a system of equations can be constructed based on the distance formula between two points:

[0074]

[0075]

[0076] The equations in the system can be expanded and subtracted pairwise to eliminate the squared terms, resulting in a linear overdetermined system of equations, which can then be written in matrix form, for example... Where A is a 2*3 matrix, and X is the target position vector to be solved. Let B be a three-dimensional constant vector. The least squares method can be used, according to the formula... Solving this system of linear overdetermined equations yields the solution vector. ,make The system of equations is minimized when the sum of squares is minimized, i.e., the overall error distance is minimized. (x', y') is then used as the positioning information for the object U to be located. Alternatively, other methods such as gradient descent can be used to solve the system of equations to obtain the positioning information of the object.

[0077] In addition to the multilateral positioning method, hyperbolic positioning method, centroid positioning method and other methods can also be used to calculate the positioning information of the object to be located based on the positioning information and ranging information of each target object. This application does not limit this method.

[0078] In some embodiments, the CCO (Centralized Coordinator) can also be connected to the carrier network constructed by the carrier modules of each object in the carrier network, so that the CCO can periodically query the location information of all objects through the carrier network, thereby obtaining the location information of the entire carrier network on the CCO side, which facilitates the user to maintain the carrier network.

[0079] The carrier network positioning method provided in this application uses a star-flash module to determine multiple target objects with positioning information, performs star-flash ranging to obtain the distance between the object to be positioned and the multiple target objects, and automatically calculates the positioning information of the object to be positioned based on the positioning information and ranging information of each target object. This method can reduce the impact of operational errors and update delays during manual recording and system entry on positioning, thereby improving the accuracy of positioning.

[0080] In some embodiments, the carrier network includes at least three positioning anchors; the positioning anchors pre-store objects with positioning information; and the target object is the positioning anchor and / or an object that has been positioned.

[0081] In this embodiment of the application, the location information of several objects can be determined by manual positioning and stored in the corresponding objects. The location information of these objects is checked and calibrated manually to ensure the accuracy of the location information, and then these objects are used as positioning anchor points.

[0082] After determining the positioning anchor points, the target object is identified from the positioning anchor points and / or the objects that have been positioned. Then, the positioning information of the object to be positioned is calculated based on the positioning information of the target object and the distance measurement information between the target object and the target object. This can improve the accuracy of the positioning information used in the calculation process, thereby improving the accuracy of the calculated positioning information.

[0083] In this embodiment, by selecting an object whose positioning information is known and / or whose positioning has been completed as the target object, and then using the target object as a reference to locate the object to be located, the impact of inaccurate positioning of the reference object on the object positioning can be reduced, thereby improving the accuracy of object positioning.

[0084] In some embodiments, the object to be located is the object closest to the positioning anchor point among the unlocated objects in the carrier network.

[0085] In this embodiment, the positioning information of the positioning anchor point is known and highly reliable, and the shorter the signal propagation distance, the less interference it is subject to. Therefore, the positioning order can be determined according to the distance between the object to be positioned and the positioning anchor point, and the object closest to the positioning anchor point is positioned first.

[0086] The positioning anchor can continuously listen to the broadcast channel after broadcasting broadcast information carrying its own device identifier, positioning information and positioning credibility; after receiving the broadcast information sent by the positioning anchor, each unpositioned object in the carrier network immediately replies to the positioning anchor with a paging message containing its own ID; the positioning anchor records the order of the received paging messages, selects the object to be positioned corresponding to the first received paging message, establishes a connection with it and performs positioning.

[0087] In this embodiment, by starting the positioning from the object closest to the object with the highest reliability of the known positioning information, the errors caused by fluctuations and losses during signal propagation can be reduced, thereby improving the accuracy of object positioning.

[0088] In some embodiments, connections are established with at least three target objects and star-flash ranging is performed to obtain ranging information between the object to be located and each target object, including: Based on the location reliability of the target object's location information, sort the target objects. Then, establish connections with at least three target objects in descending order of location reliability and perform star-flash ranging to obtain the ranging information between the object to be located and each target object.

[0089] In this embodiment, the location reliability is a numerical value that describes the accuracy of the object's location information; the higher the value, the more accurate the location information.

[0090] Users can pre-define location reliability calculation rules to determine the location reliability of each object. For example, the location reliability can be limited to a value between 0 and 100; after each location is completed, the location reliability of each object is set to 100, and the time of this location is recorded; if the location is not updated after a certain period of time, its location reliability is reduced by a certain value; the above process is repeated until the object's location information is updated.

[0091] In some embodiments, since the positioning anchor point is an object whose positioning information is known, the positioning feasibility of the positioning anchor point can be set to 100, while the positioning confidence of other objects can be calculated according to preset rules after the positioning is completed.

[0092] Location confidence can be added to the location information of an object, so that the object to be located can obtain the corresponding location confidence from the location information of each target object obtained by scanning the star network.

[0093] After obtaining the location information and corresponding location confidence level of each target object, the target objects are sorted according to their location confidence level. N target objects are then selected as location reference objects in descending order of confidence level. Here, N is an integer greater than or equal to 3. The user can pre-set the value of N to select the N target objects with the highest confidence level; alternatively, the user can pre-set a location confidence level threshold, selecting target objects with a confidence level greater than the threshold, and canceling the current location attempt when the number of target objects with a confidence level greater than the threshold is less than 3, re-locating after a period of time.

[0094] After identifying the target object, a connection is established with the target object with the highest positioning reliability and star-flash ranging is performed. Then, a connection is established with the target object with the second highest positioning reliability and star-flash ranging is performed, and so on, to obtain the ranging information between the object to be located and each target object.

[0095] In this embodiment, by selecting the object with the highest positioning confidence to establish a connection and performing star-flash ranging, the impact of inaccurate reference object positioning on positioning can be reduced, thereby improving the accuracy of object positioning.

[0096] In some embodiments, connections are established with at least three target objects and star-flash ranging is performed to obtain ranging information between the object to be located and each target object, including: Multiple rounds of distance measurement are performed on the target object to establish the connection, and distance measurement information is obtained based on the results of the multiple rounds of distance measurement.

[0097] In this embodiment, the object to be located establishes a connection with each target object and performs n star-flash ranging operations, where the value of n can be preset by the user. For example, the target objects include A, B, and C. The object to be located, U, first establishes a connection with target object A and performs n star-flash ranging operations to obtain n ranging results {d1, d2, ..., dn}, where di is the physical distance between U and A obtained from the i-th ranging operation.

[0098] Based on the obtained n distance measurement results, the distance measurement information between U and A is determined. For example, the average value d of {d1, d2,..., dn} can be calculated and used as the distance measurement information dA between U and A.

[0099] After obtaining dA, U and B are connected and n star flash ranging tests are performed. The average value dB of the n ranging results is calculated as the positioning information of U and B... and so on, to obtain the ranging information of the object to be located U and the target objects A, B, and C.

[0100] In this embodiment, by performing multiple rounds of ranging on the target object to which the connection is established, and obtaining ranging information based on the results of multiple rounds of ranging, the impact of errors in a single ranging measurement on the ranging information can be reduced, thereby improving the accuracy of object positioning.

[0101] In some embodiments, multiple rounds of ranging are performed on the target object for establishing the connection, and ranging information is obtained based on the results of the multiple rounds of ranging, including: Calculate multiple sets of candidate ranging information and corresponding ranging confidence levels obtained from multiple rounds of ranging; The candidate ranging information with the highest ranging confidence level is determined as the ranging information.

[0102] In this embodiment, the ranging reliability is a numerical value describing the accuracy of a given ranging information; a higher value indicates greater accuracy. The user can pre-define the ranging reliability calculation rules to determine the reliability of each ranging piece of information. For example, the ranging reliability can be limited to a value between 0 and 100, and determined based on factors such as the device status and working environment during the ranging process.

[0103] After the object U to be located and the target object A are connected, U and A perform n distance measurements, and n candidate distance measurement information and corresponding distance measurement confidence are calculated. ,in This represents the candidate ranging information obtained from the i-th ranging measurement. for The corresponding ranging reliability will be The highest value The distance measurement information between the object to be located, U, and the target object, A, has been determined. .

[0104] In this embodiment, by determining the candidate ranging information with the highest ranging confidence as the ranging information, the impact of errors in the ranging information on positioning can be reduced, thereby improving the accuracy of object positioning.

[0105] In some embodiments, the ranging reliability is determined based on at least one of the following: the strength of the star-flash communication signal, the degree of signal interference, and the dispersion of the ranging data.

[0106] In this embodiment, the signal strength of the StarScan communication describes the strength and stability of the wireless signal transmission between StarScan devices. The RSSI (Received Signal Strength Indicator) value during the ranging process can be statistically analyzed as an evaluation index of the StarScan communication signal strength. RSSI is a relative measurement representing the power of the radio signal detected by the receiver from the transmitter; it is a negative value in dBm. The obtained RSSI can be standardized for easier calculation, for example, to a value between 0 and 100. , as the intensity component of the star-flash communication signal.

[0107] Signal interference describes the extent to which a useful signal is affected by unwanted signals during signal transmission. The SINR (Signal to Interference plus Noise Ratio) value during ranging can be statistically analyzed as an evaluation metric for signal interference. SINR is a value measured in dB, representing the ratio of useful signal power to the sum of interference and noise power. The obtained SINR can be standardized for easier calculation, for example, to a value between 0 and 100. , as a component of signal interference level.

[0108] Ranging data dispersion describes the degree of dispersion of the data obtained during the ranging process. For example, when obtaining candidate ranging information... During the process, the object to be located, U, and the target object, A, repeated the process of "sending ranging signal - replying with confirmation signal" k times, and calculated k distance values. It can be calculated The standard deviation was calculated and standardized to obtain a value between 0 and 100. , as the dispersion component of the ranging data.

[0109] A weighted fusion method can be used, according to the formula. Calculate candidate ranging information Ranging reliability .in, , , These are the weights for the star-flash communication signal strength, signal interference level, and ranging data dispersion, respectively, used to control the dependence of ranging reliability on each component. , , The sum is 1. Users can preset the weight values ​​or set dynamic weight calculation rules to dynamically adjust the weights of each component according to the actual situation.

[0110] In addition to the strength of the star-flash communication signal, the degree of signal interference, and the dispersion of ranging data, other indicators can be introduced to determine the reliability of ranging, such as system status and the proportion of outliers. This application does not limit these indicators.

[0111] In this embodiment, by determining the ranging reliability based on at least one of the following: the strength of the star-flash communication signal, the degree of signal interference, and the dispersion of ranging data, and then determining the candidate ranging information with the highest ranging reliability as the ranging information, the influence of factors such as signal attenuation and multipath effect on the ranging information in complex environments can be reduced, thereby improving the accuracy of object positioning.

[0112] In some embodiments, the carrier network positioning method further includes: The location reliability of the object to be located is calculated based on the location reliability of the location information and the distance reliability of the distance measurement information of each target object.

[0113] In this embodiment of the application, the positioning information of the object U to be located is calculated based on the positioning information and ranging information of each target object. Therefore, the positioning reliability of the object U to be located is calculated based on the positioning reliability of the positioning information of each target object and the ranging reliability of the ranging information.

[0114] Users can pre-define location reliability calculation rules, and the system will perform calculations according to these preset rules. For example, location reliability thresholds and ranging reliability thresholds can be set. Data with both location reliability and ranging reliability greater than the corresponding thresholds will be considered qualified, while data otherwise deemed unqualified. The system can calculate the ratio of qualified data to the total data volume and standardize it to a value between 0 and 100. This standardized value will then be used as the location reliability corresponding to the location information of the object U to be located.

[0115] In this embodiment, the positioning confidence level of the object to be located is calculated based on the positioning confidence level corresponding to the positioning information and the ranging confidence level corresponding to the ranging information of each target object, which can provide a reference for other objects to be located.

[0116] In some embodiments, according to the formula:

[0117] Calculate the location reliability corresponding to the location information of the object to be located; in, This indicates the location reliability of the location information corresponding to the object to be located. This indicates the number of target objects involved in calculating the location information of the object to be located. This represents the location reliability corresponding to the location information of the i-th target object. To determine the credibility weight, This represents the ranging confidence level between the object to be located and the i-th target object. This represents the reliability weight of the ranging measurement.

[0118] It should be noted that since the location information of the anchor point is known, the location reliability of the anchor point is the highest. Taking the location reliability value as 0-100 as an example, the location reliability of the anchor point is 100. Therefore, when the target object is the anchor point, the location reliability is 100.

[0119] In this embodiment, the reliability of the data provided by each object is calculated, and then the average value is used as the location reliability corresponding to the location information of the object to be located. For the data {location information, ranging information} provided by the i-th object, a location reliability weight is assigned. And ranging confidence weight ,according to and Location reliability and ranging reliability Weighted fusion is performed. Among them, and It can be a predetermined value set by the user, or it can be dynamically calculated according to the weight calculation rules set by the user.

[0120] In this embodiment, by calculating the weighted sum of the location reliability and ranging reliability of each target object participating in the positioning, and using the average value as the location reliability corresponding to the location information of the object to be located, the reliability of each data source can be comprehensively evaluated to assess the location reliability of its own location information, thereby reducing the impact of the inaccuracy of the reliability of a single data source on the location reliability calculation.

[0121] In some embodiments, the method further includes: Broadcast information carrying device identifiers, location information, and location credibility in the StarNet network.

[0122] Broadcasting is a communication method in which a sender simultaneously transmits information unidirectionally to multiple receivers. Receivers do not need to establish or maintain a connection with the sender to receive the data. Broadcast information is information transmitted unidirectionally from the sender to each receiver; it can be a broadcast frame encapsulated according to a communication protocol, with relevant data written into the effective data payload of the broadcast frame.

[0123] In this embodiment of the application, after each object completes its positioning, it can write the device identifier, positioning information and positioning confidence into the effective data payload, and encapsulate it into a StarSpark broadcast frame according to the frame structure specified by the StarSpark communication protocol, as broadcast information; after encapsulation, it can be broadcast according to the broadcast channel and repetition number specified by the StarSpark communication protocol.

[0124] Each device in the SparkLink network can continuously scan the broadcast channel and monitor the broadcast information sent by other devices in the surrounding environment; after receiving the broadcast information, it analyzes the broadcast frame according to the SparkLink communication protocol, extracts the effective data payload, and obtains information such as the device identifier, location information, and location confidence of the sender object from it.

[0125] In this embodiment, by making the broadcast information include the device identifier, location information, and location confidence, the location data of the objects that have completed location can be propagated to the entire carrier network, enabling each object to be located to determine multiple target objects with location information through network scanning for location.

[0126] In some embodiments, the carrier network location method further includes: When the preset conditions are met, re-locate the object to be located to obtain the location information and corresponding confidence level after re-location; Compare the location confidence levels corresponding to the location information before and after re-location to update the location information of the object to be located.

[0127] In the embodiments of the present application, the location information obtained by a single location may have an error from the true location information due to factors such as signal fluctuations and environmental changes. Therefore, the user can preset the update conditions in advance, and when the preset conditions are met, re-locate the object.

[0128] For example, a location information confidence threshold E can be set. If the location confidence level R corresponding to the location information P of the object U to be located is R < E, it is determined that the preset adjustment is met, and U is re-located to obtain the location information P' after re-location and the corresponding location confidence level R'. Compare R and R', if R ≤ R', then update the location information of U to P'. Of course, the preset condition can also be that the time since the last location reaches a certain duration, and the embodiments of the present application do not limit this.

[0129] In this embodiment, by re-locating the object to be located when the preset conditions are met and updating the location information of the object to be located according to the result of re-location, the influence of the error existing in a single location on object location can be reduced, thereby improving the accuracy of object location.

They periodically broadcast broadcast information carrying device identifiers, location information, and location credibility in the StarScan network. The StarScan module of the electricity meter to be located responds to the location command issued by the carrier module, scans the StarScan network, identifies multiple target electricity meters with location information, and sorts the target electricity meters according to the location credibility corresponding to the location information of each target electricity meter. The top 3 in the sorting result are target electricity meters 1, 2, and 3, respectively.

[0131] The energy meter to be located first establishes a connection with the target energy meter 1, and performs multiple rounds of ranging to obtain multiple sets of candidate ranging information and corresponding ranging confidence levels. The candidate ranging information with the highest ranging confidence level is then determined as the ranging information. Its ranging reliability is Following the same process, the distance information between the energy meter to be located and the target energy meter 2 is obtained. and ranging reliability Distance information between the energy meter to be located and the target energy meter 3 and ranging reliability .

[0132] After ranging is completed, the location information P and location reliability R of the target energy meter are calculated according to a preset method based on the location information and ranging information of each target energy meter. After the calculation is completed, a broadcast message carrying the device identifier, location information and location reliability is broadcast in the StarNet network.

[0133] The CCO periodically queries the location information of all electricity meters through the carrier network, thereby obtaining the location information of the entire network on the CCO side.
