[0029] Figure 1 This is a flow chart of a test data generation method provided according to an embodiment of the present invention. This embodiment is applicable to the case of generating test data for debugging a positioning engine. The method can be executed by a test data generation device, which can be implemented in the form of hardware and / or software.

[0030] like Figure 1 As shown, the method of this embodiment may specifically include:

[0031] S110 . In response to a debugging trigger operation on a current positioning engine to be debugged, sending pre-stored real position relationship data between a preset sampling point in a target field area and at least one preset beacon to the current positioning engine to be debugged.

[0032] The target site area is the test area specified according to the test requirements; for example, the target site area may include chemical plants and coal mines. The preset sampling point is the location in the preset target site area where the positioning data needs to be determined; the preset beacon is a preset positioning beacon, which is a device composed of radio signals and is used to provide location information. The current positioning engine is the positioning engine that currently needs to be debugged.

[0033] In this embodiment, the debugging trigger operation of the current positioning engine to be debugged includes: clicking the debugging control displayed on the display interface, receiving a voice command to debug the current positioning engine, and the current time being a preset debugging time. Among them, the display interface is used to show the developer an interface of the debugging process of the current positioning engine.

[0034] In this embodiment, the number of preset sampling points and preset beacons can be multiple, and the preset sampling points can be multiple constituent points in the preset sampling trajectory. For each pair of preset sampling points and preset beacons, there is a corresponding real position relationship data. It should be noted that, since the preset sampling points and preset beacons are real and fixed positions, the real position relationship data between the preset sampling points and the preset beacons are also real and fixed data. After the triggering debugging operation is detected, the determined real position relationship data between each preset sampling point and each preset beacon can be sent to the current positioning engine to be debugged.

[0035] The real position relationship data may include distance data and azimuth data; the distance data is used to indicate the distance between the preset sampling point and the preset beacon, and the azimuth data is used to indicate the direction angle between the preset sampling point and the preset beacon. The distance data and azimuth data reflect the real position relationship between the preset sampling point and the preset beacon.

[0036] In a specific implementation, the real position relationship data between the preset sampling points and at least one preset beacon in the pre-stored target field area are sent to the current positioning engine to be debugged, including: when a stress test instruction is received, determining a data replication multiple based on the stress test instruction; performing data replication operations on the real position relationship data between the preset sampling points and different preset beacons according to the data replication multiple to form a position relationship data set.

[0037] Wherein, the data replication multiple is greater than the preset multiple value; the position relationship data set is sent to the current positioning engine to be debugged. Exemplarily, the preset multiple value is set to 1 by default.

[0038] In practical applications, in order to ensure the operational stability of the positioning engine, it is usually necessary to perform a stress test on the positioning engine. In this embodiment, if a stress test instruction is received, the stress test instruction can be parsed to determine the data replication multiple. For example, the data replication multiple can be 10 times. According to the data replication multiple, a data replication operation is performed on the real position relationship data between all preset sampling points and different preset beacons. For example, each real position relationship data is replicated 10 times, and for each set of replicated position relationship data, a simulated terminal identifier of a simulated positioning engine is constructed. The original real position relationship data and the replicated position relationship data obtained after the replication operation are combined into a position relationship data set.

[0039] In order to detect the operating stability of the current positioning engine, the position relationship data in the position relationship data set can be sent to the current positioning engine at the same time to detect whether the current positioning engine can completely receive all the data in the position relationship data, and can perform positioning processing on all the position relationship data in the position relationship data set to obtain the positioning data corresponding to all sampling terminals.

[0040] In this embodiment, the real position relationship data is copied, and the position relationship data set obtained after the copying data is sent to the current positioning engine to implement a stress test on the current positioning engine, which is beneficial to improving the operating stability of the current positioning engine.

[0041] S120: receiving sampling positioning data of preset sampling points sent by the current positioning engine, and forming test data for the current positioning engine from the real position data of the preset sampling points acquired in advance and the sampling positioning data.

[0042] The sampled positioning data is the position data reflecting the preset sampling point determined by the current positioning engine based on the received real position relationship data and the real position data of the preset beacon.

[0043] In a specific implementation, for each preset sampling point, after the real position relationship data between the preset sampling point and at least one preset beacon is sent to the current positioning engine, the current positioning engine determines the position data of the preset sampling point determined by the current positioning engine, i.e., the sampling positioning data, based on the real position relationship data and the real position data of the preset beacon corresponding to the real position relationship data. Exemplarily, the real position data may include the real latitude and longitude data and the real altitude data of the preset beacon.

[0044] In order to accurately test the current positioning engine and improve the debugging results, the real position data of each preset sampling point and the sampled positioning data can be used to form the test data.

[0045] In order to facilitate developers to view test data, optionally, after forming the test data for the current positioning engine, it also includes: displaying the real position of the preset sampling point on a pre-loaded electronic map according to the real position data and the first preset display method; displaying the sampling position of the preset sampling point determined by the current positioning engine on the electronic map according to the sampling positioning data and the second preset display method.

[0046] Among them, the first preset display method is different from the second preset display method, and the first preset display method can be at least one of displaying in a solid circle, displaying in bold, and displaying in a first color; the second preset display method includes at least one of flashing display, displaying in a dotted circle, and displaying in a second color, and the first color is different from the second color.

[0047] Specifically, an electronic map corresponding to the target site area may be preloaded. Based on the real location data, the real location of each preset sampling point on the electronic map is determined, and based on the first preset display method, the real location is displayed on the electronic map, so that the developer can intuitively see the real location of the preset sampling point on the electronic map.

[0048] Furthermore, in order to facilitate the comparison of the deviation between the sampling position determined by the current positioning engine and the actual position, so as to demonstrate the positioning accuracy of the current positioning engine, the sampling position of each preset sampling point on the electronic map can be determined based on the sampling positioning data, and the sampling position can be displayed on the electronic map based on the second preset display method. Since the first preset display method is different from the second preset display method, the actual position and sampling position of the same preset sampling point are displayed differently on the electronic map, which is convenient for developers to distinguish.

[0049] In addition, in the case where there are multiple preset sampling points, in order to distinguish different preset sampling points on the electronic map, for each preset sampling point, the sampling point identifier of the preset sampling point can be marked at the real position and sampling position of the preset sampling point on the electronic map. The sampling point identifiers of different preset sampling points are different. By marking the sampling points, it is convenient for developers to distinguish different preset sampling points, and the real position and sampling position can be displayed more clearly and effectively. Furthermore, the electronic map after displaying the real position and sampling position can be displayed in three dimensions, so that developers can more intuitively understand richer information.

[0050] In this embodiment, the real location and the sampling location are displayed on the electronic map, which is convenient for developers to view and provides convenience for developers to debug the current positioning engine.

[0051] Optionally, the sampling positions of the preset sampling points determined by the current positioning engine are displayed on the electronic map according to the sampling positioning data and the second preset display mode, including: when there are multiple preset sampling points, the sampling positions corresponding to each preset sampling point are displayed on the electronic map in sequence according to the sampling positioning data and the second preset display mode in the order of the sampling moments corresponding to the preset sampling points from the earliest to the latest; and the sampling positions are connected on the electronic map according to the preset connection mode to display the sampling trajectory composed of each sampling position.

[0052] It should be noted that in order to debug the current positioning engine more accurately, a sampling trajectory can be preset, and the sampling trajectory consists of multiple preset sampling points. In order to reflect the sampling trajectory on the electronic map, the sampling time of each preset sampling point can be determined from the pre-stored sampling log file, and the preset sampling points can be sorted in order from the sampling time from the earliest to the latest. In order from the smallest to the largest sorting value, the sampling positions corresponding to the sampling positioning data of each preset sampling point are displayed on the electronic map in sequence.

[0053] Furthermore, after the sampling positions of each preset sampling point are displayed on the electronic map, the sampling positions can be connected in sequence according to the display order and the preset connection method, so as to display the sampling trajectory composed of each sampling position. For example, the preset connection method may include a dotted line connection method and an arrow connection method.

[0054] In this embodiment, the sampling positions corresponding to the multiple preset sampling points are connected to display the sampling trajectory, and the sampling process is dynamically displayed, so that the developers can have a more comprehensive understanding of the sampling process, which is conducive to debugging the positioning effect of the current positioning engine on the dynamic motion process.

[0055] The technical solution of the embodiment of the present invention, in response to the debugging trigger operation of the current positioning engine to be debugged, sends the real position relationship data between the preset sampling point and at least one preset beacon in the pre-stored target field area to the current positioning engine to be debugged; since the preset sampling point and the preset beacon are both fixed positions, it means that the real position relationship data between the preset sampling point and the preset beacon is also the relationship data between the real fixed positions, which does not change with time; by receiving the sampled positioning data of the preset sampling point sent by the current positioning engine, the real position data and the sampled positioning data of the preset sampling point obtained in advance are used to form the test data for the current positioning engine. The technical solution provided by this embodiment, since the fixed real position relationship data is pre-stored, each time the current positioning engine to be debugged is debugged, the test data can be determined by the pre-stored real position relationship data, without the need to go to the preset sampling point in the target field area for re-sampling, avoiding the staff from frequently entering and exiting the dangerous target field area, improving the debugging safety and debugging efficiency, and reducing the human resource consumption.

[0056] Figure 2 It is a flowchart of another test data generation method provided according to an embodiment of the present invention. Based on the above embodiment, this embodiment also includes: receiving signal characteristic data between a preset sampling point and at least one preset beacon in a target field area sent by a sampling terminal within a preset sampling time period; wherein the signal characteristic data includes signal strength data and signal direction data; based on the signal strength data, determining the distance data between the preset sampling point and at least one preset beacon, determining the distance data and the signal direction data as the real position relationship data between the preset sampling point and at least one preset beacon, and storing the real position relationship data. Among them, the explanations of the terms that are the same or corresponding to the above embodiments are not repeated here.

[0057] like Figure 2 As shown, the method includes:

[0058] S210, receiving signal characteristic data between a preset sampling point and at least one preset beacon in a target field area sent by a sampling terminal within a preset sampling time period; wherein the signal characteristic data includes signal strength data and signal direction data.

[0059] It should be noted that the preset sampling time period may be a preset time period for collecting information from the preset sampling points. In order to reduce the impact of the sampling process on the work of the target field area, the preset sampling time period may be set to weekends or nighttime.

[0060] In the actual sampling process, the number of sampling terminals can be multiple, and a staff member or an autonomous driving vehicle carrying a sampling terminal moves to a preset sampling point in the target field area, and collects signal characteristic data between the preset sampling point and at least one preset beacon. Furthermore, if the preset sampling point is a component point of a preset trajectory, the sampling terminal can be moved to each preset sampling point corresponding to the preset trajectory in sequence according to the trajectory sequence of the preset trajectory, and the signal characteristic data corresponding to the preset sampling point can be collected.

[0061] In a specific implementation, the collected signal characteristic data, the terminal identifier of the sampling terminal and the sampling time corresponding to the signal characteristic data can be sent to a test data generating device in sequence from front to back according to the collection time of the signal characteristic data. The test data generating device receives the signal characteristic data sent by at least one sampling terminal.

[0062] S220. Determine distance data between a preset sampling point and at least one preset beacon based on the signal strength data, determine the distance data and the signal direction data as real position relationship data between the preset sampling point and at least one preset beacon, and store the real position relationship data.

[0063] In order to improve the accuracy of the real position relationship data, before determining the distance data between the preset sampling point and at least one preset beacon based on the signal strength data, it also includes: determining the data in the signal characteristic data that meets the preset filtering conditions as abnormal data in the signal characteristic data, and marking or removing the abnormal data.

[0064] The preset screening condition includes at least one of the following: data whose signal strength value is lower than a preset strength threshold; data whose signal direction data exceeds a preset direction range; and data whose data receiving time interval is inconsistent with a preset interval.

[0065] In this embodiment, the signal characteristic data whose signal strength value is lower than the preset strength threshold value can be used as abnormal data in the following manner: determine the signal strength value corresponding to each signal strength data, and use the minimum signal strength value that the preset beacon can generate at a specified distance as the preset strength threshold value, and use the signal characteristic data whose signal strength value is lower than the preset strength threshold value as abnormal data. In addition, the abnormal data can also be determined based on the signal direction data in the signal characteristic data. Exemplarily, based on the location of the preset beacon in the target field area and the regional structure of the target field area, the direction range in which sampling can be performed is determined as the preset direction range. For example, in the direction a, because there is a large chemical equipment, the area cannot be entered, and the direction a is not included in the direction range. Signal characteristic data whose signal direction data exceeds the preset direction range can be used as abnormal data.

[0066] Furthermore, the time interval between the receiving times corresponding to two adjacent received signal characteristic data may be used as the data receiving time interval, and the signal characteristic data whose data receiving time interval is inconsistent with the preset interval may be used as abnormal data.

[0067] After determining the abnormal data, in order not to affect the accuracy of the real position relationship data, the abnormal data can be eliminated to determine the real position relationship data based on the signal feature data remaining after eliminating the abnormal data; or, the abnormal data can be marked, and the anti-interference ability of the positioning engine can be tested by the marked abnormal data.

[0068] This embodiment determines abnormal data in the signal feature data and marks or removes the abnormal data, thereby improving the accuracy of determining the real position relationship data and improving the anti-interference ability of the positioning engine.

[0069] In this embodiment, the distance between the preset sampling point and the preset beacon can be reflected by the magnitude of the signal strength. Specifically, based on each received signal strength data, the distance data between the preset sampling point and the preset beacon corresponding to the signal strength data can be determined. The real position relationship data between the preset sampling point and the preset beacon is composed by the distance data and the signal direction data. Furthermore, the real position relationship data can be stored according to the collection time and terminal identification corresponding to each received signal feature data.

[0070] This embodiment provides a method for obtaining real position relationship data, which can ensure the accuracy and authenticity of the real position relationship data and facilitate the debugging of the current positioning engine.

[0071] In order to be able to store the real position relationship data in an orderly and clear manner, optionally, before storing the real position relationship data, it also includes: establishing a collection folder for each unit collection period included in a preset sampling time period; when there are multiple sampling terminals, generating an independent log file corresponding to each sampling terminal in each pre-established collection folder; storing the real position relationship data, including: based on the collection time and sampling terminal corresponding to the signal characteristic data, determining the storage folder and storage log file of the real position relationship data corresponding to the signal characteristic data; storing the real position relationship data in the storage log file of the storage folder.

[0072] Specifically, the preset sampling time period may include multiple unit sampling cycles. Exemplarily, the preset sampling time period is one week, and the unit sampling period is from 8:00 to 12:00 every day included in the week. Since the number of sampling terminals is large and the preset sampling time period lasts for a long time, the amount of real position relationship data generated is large. In order to facilitate searching, a collection folder can be established for each unit collection period. The collection folder is used to store the real position relationship data determined by the unit collection period.

[0073] Furthermore, for each sampling terminal, an independent log file corresponding to each sampling terminal may be generated in each collection folder, and the file name of the independent log file may be the terminal identifier of the sampling terminal. For any independent log file in any collection folder, it is used to record the real position relationship data determined by the signal feature data collected by the sampling terminal corresponding to the independent log file in the unit collection cycle corresponding to the collection folder.

[0074] In a specific implementation, based on the acquisition time corresponding to the signal characteristic data, a collection folder matching the acquisition time can be determined as a storage folder, that is, the unit acquisition period corresponding to the storage folder includes the acquisition time. Based on the terminal identification of the sampling terminal of the signal characteristic data, an independent log file with a file name consistent with the terminal identification is determined as a storage log file. The determined real position relationship data corresponding to the signal characteristic data is stored in the storage log file of the storage folder. Optionally, when storing the real position relationship data, it can be stored in the order of the acquisition time.

[0075] S230: In response to a debugging trigger operation on the current positioning engine to be debugged, the pre-stored real position relationship data between the preset sampling point in the target field area and at least one preset beacon are sent to the current positioning engine to be debugged.

[0076] S240: Receive sampling positioning data of preset sampling points sent by the current positioning engine, and form test data for the current positioning engine with the real position data of the preset sampling points acquired in advance and the sampling positioning data.

[0077] In this embodiment, the real position relationship data is stored in folders and files according to the different sampling terminals and unit collection cycles, thereby facilitating data search and use; and for each debugging process, there is no need to repeatedly obtain signal characteristic data in the target field area, which improves debugging convenience and saves human resources.

[0078] The embodiments corresponding to the test data generation method are described in detail above. In order to make the technical scheme of the method further clear to those skilled in the art, the working process of the test data generation system that executes the test data generation method is described below.

[0079] In this embodiment, the test data generation system includes a data storage subsystem, a data analysis subsystem, a data display subsystem and a data forwarding subsystem. The working contents of each subsystem are as follows:

[0080] 1. Data storage subsystem

[0081] The data storage subsystem is connected to the current positioning engine. Without affecting the operation of the current positioning engine, it automatically obtains and saves the signal characteristic data uploaded by the sampling terminal, and generates various sampling folders according to the period. In each sampling folder, an independent log file is generated according to the terminal identification of the sampling terminal. The independent log file can store signal characteristic data and signal characteristic data.

[0082] In order to reduce storage pressure and avoid hard disk space being occupied, when the data occupancy of the hard disk space reaches the preset occupancy threshold, the sampling folder corresponding to the preset number of retrospective days can be compressed or deleted according to the preset number of retrospective days; and the hard disk space occupancy information can also be detected in real time.

[0083] 2. Data analysis subsystem

[0084] The data analysis subsystem can load the signal feature data in one or more independent log files, and sort the data based on the acquisition time corresponding to the signal feature data, so as to facilitate data search and detect the integrity of the data. In addition, the recording time and quantity of the signal feature data and the alarm information status of the sampling terminal corresponding to the signal feature data during the sampling process can be recorded. The working status of the sampling terminal is reflected by the alarm information status. After the data loading is completed, the abnormal data in the signal feature data can be determined, and the abnormal data can be marked or removed.

[0085] Furthermore, the data analysis subsystem can search the loaded independent log files through the received keywords to check whether the specified information exists in the signal characteristic data reported by the sampling terminal. For example, the beacon identifier of the specified preset beacon can be searched in the independent log file to check and determine whether the sampling terminal has effectively read and reported the signal characteristic information between the preset beacon and the preset sampling point, so as to determine whether the communication between the sampling terminal and the preset beacon is normal.

[0086] In addition, after receiving the data selection instruction, the data analysis subsystem can determine the collection time, reporting time, distance data and signal direction data corresponding to the data selection instruction and the information of the sampling terminal, wherein the information of the sampling terminal includes power and alarm status.

[0087] 3. Data display subsystem

[0088] The data display subsystem loads an electronic map corresponding to the target site area, and graphically displays the real position and sampling position of the preset sampling point on the electronic map. The data display subsystem supports single display and continuous playback. Single display means that for any preset sampling point, the beacon mark of the preset beacon associated with the preset sampling point is indicated with a bright spot on the electronic map, and the distance between the preset sampling point and the preset beacon is displayed in a circle. The sampling position is marked with a preset specified color, and the sampling position can be the satellite positioning position determined by the current positioning engine. Continuous playback refers to the automatic and continuous display of the real position and sampling position of each preset sampling point in a preset trajectory. By displaying real data and sampling data, the position changes of the sampling terminal during the movement process are very vivid, so that developers can check the scenarios and causes of positioning anomalies and perform targeted optimization.

[0089] 4. Data forwarding subsystem

[0090] The data forwarding subsystem can be connected to the current positioning engine and send the real position relationship data in the independent log file to the current positioning engine. Specifically, the real position relationship data can be sent to the current positioning engine. For each debugging process, when sending the real position relationship data, the terminal identifier of the sampling terminal can be reset to avoid the real position relationship data being sent to the current positioning engine. The data overlaps with the historical position relationship data received during the previous debugging of the current positioning engine, causing interference to the current positioning engine.

[0091] In order to stress test the current positioning engine, multiple independent log files can be loaded, and the data replication multiple can be set; the real position relationship data in the loaded independent log files can be copied according to the data replication multiple; and the simulated terminal identifier corresponding to the copied position relationship data can be set based on the real terminal identifier of the sampling terminal corresponding to the real position relationship data. Exemplarily, when the data replication multiple is 10, if the real terminal identifier is 100, after copying the real position relationship data obtained by the sampling terminal with the real terminal identifier of 100, the simulated terminal identifiers corresponding to the copied position relationship data obtained each time can be 101, 102, 103, ..., 110 respectively; that is, the simulated terminal identifier corresponding to the copied position relationship data obtained each time can be obtained by adding 1 to the real terminal identifier. Through stress testing, the data receiving and sending and data processing capabilities of the current positioning engine are tested.
