In the prior art, a terminal device (e.g., a mobile phone or a vehicle) can be located through a GNSS module carried by the terminal device, but a GNSS signal is blocked to cause a failure in location, and for this reason, the prior art provides a multi-source fusion location technology that continuously outputs a location position of the terminal device through various signal source (GNSS, base station, Wifi, bluetooth, sensor, etc.) data received or scanned by the terminal device, an online location algorithm deployed on a service side, an offline location algorithm deployed on the terminal device side, and a related scheduling policy. It can be seen that the source data is the basis for the localization algorithm to continuously output the localization position.
In the case where the positioning algorithm and the positioning logic are not changed, the accuracy of the positioning position of the terminal device (referred to as positioning accuracy for short) may be affected by the accuracy of the signal source data received or scanned by the terminal device. The self state of the terminal equipment and the environmental factors of the area where the terminal equipment is located can affect the accuracy of signal source data received or scanned by the terminal equipment, the accuracy reduction of the signal source data can cause the reduction of positioning accuracy, and once the positioning accuracy is reduced, various services (navigation service, network appointment service, life service and the like) based on the positioning position can be affected. Therefore, in the situation that the state of the terminal device itself or environmental factors are uncontrollable and unpredictable, how to ensure the predictability of the positioning position is a problem to be solved by those skilled in the art.

In the above operating environment, the present application provides a signal source processing method as shown in fig. 2. Fig. 2 is a flowchart of a signal source processing method according to a first embodiment of the present application, and as can be seen from fig. 2, the method at least includes the following steps:
step S202, signal source data generated by a signal source scanned by the terminal equipment currently is obtained, wherein the signal source data is used for predicting a positioning result corresponding to the current environment.
In step S202, the current environment may be an environment in which the object to be positioned is located, where the object to be positioned may be a vehicle, a person, an animal, or the like. Optionally, when the object to be located is a vehicle, the terminal device may be set in the vehicle, and the terminal device may acquire multiple types of signal sources in the current environment, for example, the terminal device may be a navigation system in the vehicle, or may be a device (e.g., a mobile phone) with a navigation function held by a person in the vehicle; in the case that the object to be positioned is a person, the person holds a terminal device which can acquire multiple types of signal sources in the current environment, wherein the terminal device is a device (for example, a mobile phone) with a navigation function held by the person.
In step S202, the signal source is a System signal that is required to be used for positioning, and includes, but is not limited to, information collected by a GNSS (Global Navigation Satellite System), information collected by a base station, WIFI information, bluetooth information, and information collected by a related sensor.
In an optional embodiment, the vehicle is provided with a terminal device, and the terminal device acquires multiple types of scanned signal sources in the driving process of the vehicle in real time, for example, the terminal device is provided with a WIFI module, which can acquire WIFI information (for example, the number of WIFI signals, the intensity of the WIFI signals, and the like) that can be detected around the vehicle; the terminal equipment can also be provided with a Bluetooth module which can detect the equipment needing Bluetooth connection around the vehicle; the terminal device may also have a temperature sensor, a humidity sensor, etc., which may acquire environmental information (e.g., ambient temperature, humidity, etc.) around the vehicle. In addition, the terminal device may also acquire the location information of the vehicle based on the GNSS, and may also acquire information such as location information of the base station, device information, and the like.
It should be noted that, in the above description, the current environment is taken as an outdoor environment as an example, in practical applications, the current environment may also be an indoor environment, for example, a user holds a terminal device (e.g., a mobile phone) to move indoors, and at this time, the terminal device acquires signal source data generated by a signal source scanned in the indoor environment.
And step S204, recording the signal source data generated by the signal source to obtain a recording result.
In step S204, the required signal source data may be recorded in a database manner, optionally, the database may be a cloud database, and in this scenario, after the terminal device records the signal source data, the recording result is sent to the cloud database for storage.
It should be noted that, by the recording method in step S204, the variable environment can be fixed, thereby reducing the influence of the environmental change on the positioning result.
And step S206, playing back the recording result to obtain a positioning result.
In step S206, the playback of the recording result is the playback of the recorded signal source data, and optionally, the playback of the recording result may be performed according to the recording sequence of the signal source data. And the recording result can be played back to the positioning software development kit so as to realize the position positioning of the terminal equipment through the positioning software development kit.
It should be noted that, through step S206, uncontrollable system signal source data can be replaced by played-back signal source data, so that the predictability of the positioning result output can be ensured with a high probability, and after the recording result is played back for multiple times, the obtained positioning result is the same, so that the accuracy of the positioning result determined based on the playback result is ensured.
In addition, it should be noted that, in the conventional navigation system, only the signal source data in the navigation scene can be played back by means of the positioning engine log, and the signal source data of other scenes (for example, indoor scenes) cannot be played back. The signal source data of the current scene is recorded, the current scene can be an outdoor scene, an indoor scene or a main scene, and in practical application, an application method of an upper layer service and an application scene of the upper layer service do not need to be considered, so that playback of the signal source data of the whole scene is realized, and the scheme provided by the application has a wider application scene.
Based on the schemes defined in steps S202 to S206, it can be known that, in the embodiment of the present application, a method of recording signal source data generated by a signal source currently scanned by a terminal device is adopted, and after signal source data generated by a signal source currently scanned by the terminal device and used for predicting a positioning result corresponding to a current environment is generated, signal source data generated by the signal source is recorded to obtain a recording result, and then the recording result is played back to obtain the positioning result.
It is easy to note that, in the above process, the signal source data is data generated by the signal source currently scanned by the terminal device, that is, the signal source data generated by the signal source currently scanned by the terminal device is related to the current environment of the terminal device, therefore, in the process of recording the signal source data generated by the signal source, the variable environment can be fixed in a recording manner, and then when the signal source data is used, the recording result is played back in a playback manner, so that the uncontrollable system is replaced by the signal source for playback, the upper layer service can play back the current scene for an unlimited number of times through the played back signal source, the influence of the environment change on the positioning result is reduced, and the certainty (predictability) and accuracy of the positioning result are ensured.
Therefore, the purpose of ensuring the accuracy of the positioning result when the environment changes is achieved by the scheme provided by the application, the technical effect of accurately positioning the object to be positioned is achieved, and the technical problem that in the related technology, when the environment of the object to be positioned changes, the object to be positioned cannot be accurately positioned is solved.
In an alternative embodiment, in the process of recording the signal source data generated by the signal source, three processes of initializing the recording of the signal source, starting the recording and ending the recording are mainly involved.
Optionally, in an initialization process of recording the signal source, first, the recording configuration information is obtained, then, a database file is created based on the recording configuration information, corresponding signal source data tables are created in the database file for the different types of signal sources, respectively, a signal source manager is initialized based on the recording configuration information, the initialized signal source manager is called to add corresponding signal source recorders for the different types of signal sources, and finally, a monitoring thread corresponding to each type of signal source is initialized based on the recording configuration information.
As can be seen from fig. 3, in the process of performing recording initialization, first, the control terminal device reads recording configuration information, and optionally, the recording configuration information may be used to configure a database storing signal source data, where the recording configuration information includes, but is not limited to, a static data request frequency, a database entry type, a database file name, and the like.
Optionally, the static data is data that is continuously kept unchanged, and the data may be directly accessed by a terminal device or a server, for example, data of the WIFI switch (for example, 1 indicates that the WIFI switch is in an on state; 0 indicates that the WIFI switch is in an off state), memory data (for example, 1 indicates that the memory is in an occupied state, and 0 indicates that the memory is in an idle state), and power data (for example, remaining power).
In addition, the warehousing type represents the type of data written into the database file, such as a GPS data type, a WIFI data type, and the like. When the signal source data is played back, the signal source data needing to be played back can be selected through the warehousing type, and all the signal source data do not need to be played back, so that the signal source data can be played back more flexibly.
After the recording configuration information is obtained, a database file is created based on the recording configuration information, optionally, the data type stored in the database file is the data type written into the database, and the name of the database file is the name of the database file.
Further, after creating the database file, initializing a signal source manager, wherein the signal source manager can manage the signal source data, for example, the signal source manager can select a signal source of a target type to be monitored from different types of signal sources. Then, adding different types of signal source recorders, wherein the different types of signal sources are recorded by the corresponding types of signal source recorders. Optionally, the signal source recorder may write the signal source of the corresponding type into the buffer queue, and the signal source in the buffer queue is finally written into the database file.
Further, as can be seen from fig. 3, after adding different types of signal sources, different types of signal source data tables are created, and likewise, the signal source data of the different types of signal sources are stored in the different types of signal source data tables. And finally, initializing the monitoring threads corresponding to the types of the signal sources of different types, thereby realizing the initialization of the signal source recording.
In an optional embodiment, after initializing the signal source recording, recording signal source data generated by the signal source may be started, specifically, first, a monitoring thread corresponding to the type of the signal source is invoked, the signal source data generated by the signal source is monitored by the monitoring thread, then, a signal source recorder corresponding to the type of the signal source is invoked, the signal source recorder records the signal source data monitored by the monitoring thread corresponding to the type of the signal source to a cache queue corresponding to the type of the signal source, and finally, the signal source recorder writes the signal source stored in the cache queue into a signal source data table corresponding to the type of the signal source.
Optionally, fig. 4 shows an optional flowchart for starting recording, where the terminal device has a timer, and when starting to record signal source data, the terminal device starts the timer to record the time for starting recording. Then, the terminal device calls dynamic data and static data of a signal source selected from the plurality of types of signal sources through the signal source manager, wherein the dynamic data is data which continuously changes along with the movement of the object to be positioned, for example, data in a GPS list, a WIFI list and the like continuously increase along with the movement of the object to be positioned.
Then, the signal source recorder corresponding to the type of the selected signal source records the signal source data (i.e., the dynamic data and the static data) into the corresponding buffer queue through the signal source interface of each type of signal source, and finally, the signal source data in the buffer queue is written into the corresponding signal source data table in batch through the signal source recorder.
It should be noted that different types of signal sources correspond to different types of signal source interfaces, different types of signal sources correspond to different signal source recorders, and different types of signal sources correspond to different signal source data tables, wherein signal source data are recorded into corresponding buffer queues through the signal source interfaces, the signal source interfaces have universality, and a problem that different systems can only be compatible with corresponding data formats can be avoided.
In an alternative embodiment, as shown in fig. 4, before writing the signal source data stored in the buffer queue into the signal source data table corresponding to the type of the signal source, it is necessary to determine the storage amount of the signal source data in the buffer queue and the size of the preset threshold. Specifically, in the process of monitoring the signal source data by calling the monitoring thread corresponding to the type of the signal source, whether the storage amount of the cache queue is greater than a preset threshold value is judged, and when the storage amount of the cache queue is determined to be greater than the preset threshold value, the signal source data stored in the cache queue is written into the signal source data table, and the signal source data written into the signal source data table is deleted from the cache queue.
In another optional embodiment, when the duration that the storage amount of the buffer queue is not greater than the preset threshold exceeds the preset duration, the signal source data stored in the buffer queue may also be written into the signal source data table in batch, for example, a timer of the terminal device starts to time when the signal source data starts to be recorded, and when the signal source manager detects that the storage amount in the buffer queue of a certain type of signal source does not reach the preset threshold for a long time, the signal source recorder corresponding to the type of signal source writes the signal source data in the buffer queue of the corresponding type into the signal source data table of the corresponding type. The process can avoid the problem that the signal source data is stored in the buffer queue for a long time, so that the memory is occupied for a long time and the system performance is influenced.
Optionally, fig. 5 shows an optional flowchart for ending recording, and as can be seen from fig. 5, before ending recording, when a listening thread corresponding to the type of the signal source stops listening to signal source data, it needs to first determine whether there is remaining signal source data that has not been written into the signal source data table in the cache queue; when determining that the residual signal source data exist in the buffer queue, writing the residual signal source data into a signal source data table, and deleting the residual signal source data written into the signal source data table from the buffer queue; and when determining that the residual signal source data does not exist in the cache queue, releasing the monitoring thread and the cache queue corresponding to the type of the signal source.
It should be noted that, as can be seen from fig. 5, before the call of the listening thread corresponding to the type of the signal source is stopped, the data corresponding to the signal source manager needs to be unregistered, where the unregistering of the data corresponding to the signal source manager is implemented by stopping various signal acquisition modes.
In an optional embodiment, when the terminal device receives a control instruction for stopping data acquisition, the terminal device stops de-registering data corresponding to the signal source manager. In another optional embodiment, when the terminal device cannot acquire data, for example, the terminal device fails, or a component that acquires or receives data in the terminal device fails, the terminal device stops de-registering the data corresponding to the signal source manager, so as to avoid the problem that the acquired data has an error due to continuous data acquisition when the terminal device fails, or the component that acquires or receives data in the terminal device fails.
In an alternative embodiment, three phases are involved in the playback of the source data, namely, the initialization of the playback of the source data, the start of the playback, and the end of the playback.
Optionally, fig. 6 shows a schematic diagram of an optional playback initialization, in the process of playing back the signal source data, first obtaining playback configuration information, and initializing a database, where the playback configuration information includes, but is not limited to, a selected database file to be played back, a size of a blocking queue, a warehousing type, and the like.
It should be noted that the block queue includes signal source data waiting for playback, for example, GPS signal source data needs to be played back, and only after the playback time corresponding to the GPS signal source data reaches, the GPS signal source data is obtained from the block queue and played back, and signal source data whose playback time does not reach needs to continue waiting in the block queue until the playback time reaches, and then is taken out from the block queue.
Optionally, as can be seen from fig. 6, after the playback configuration information is obtained, the signal source manager is further initialized based on the playback configuration information, corresponding signal source playback devices are respectively added to different types of signal sources through the signal source manager, and then a working thread corresponding to each type of signal source is initialized based on the playback configuration information.
It should be noted that the signal source working thread includes: the method comprises a signal source reading thread, a signal source queue thread, a signal source distributing thread, a signal source processing thread and a signal source callback thread. The signal source reading thread is used for reading signal source data to be distributed in the database file; the signal source queue thread is used for acquiring signal source data to be distributed from the blocking queue; the signal source distribution thread is used for acquiring signal source data to be distributed; the signal source processing thread is used for processing signal source data to be distributed; the signal source callback thread is used for performing data callback on signal source data to be distributed.
In an optional embodiment, in the process of playing back the recording result, a signal source reading thread is called to read signal source data to be distributed from a database file, the signal source data to be distributed is cached to a blocking queue, then a signal source queue thread is called, the signal source queue thread acquires the signal source data to be distributed from the blocking queue according to the writing time sequence of the signal source data to be distributed when being written into the database file, and stores the signal source data to a message queue, and then the signal source distribution thread is called, and the signal source data to be distributed is acquired from the message queue according to the writing time sequence. Then determining whether the signal source data to be distributed is callback data, calling a signal source processing thread to perform byte sequence conversion processing on the signal source data to be distributed to obtain a processing result when the signal source data to be distributed is determined not to be the callback data, and storing the processing result to a memory; when the signal source data to be distributed is determined to be callback data, the signal source distribution thread is called to distribute the signal source data to be distributed to the signal source callback thread, and the signal source callback thread is called to perform data callback after the byte sequence conversion processing is performed on the signal source data to be distributed so as to obtain a positioning result.
It should be noted that the signal source processing thread at least includes a static data processing thread, where when the signal source data to be distributed is not callback data, the static data processing thread may be called to perform byte sequence conversion processing on the signal source data to be distributed, where the byte sequence conversion processing may be, but is not limited to, data deserialization processing.
In addition, it should be noted that, the signal source data to be distributed of each type of signal source has a separate blocking queue, and when the signal source data is played back, the signal source data to be distributed of the same type of signal source is played back separately. In addition, the signal source data to be distributed of each type of signal source independently has a corresponding signal source working thread, that is, the signal source reading thread, the signal source queue thread, the signal source distribution thread, the signal source processing thread and the signal source playback thread of the signal source data to be distributed of different types of signal sources are all different, so that when the corresponding signal source working thread is called to process the signal source data to be distributed of the signal source of the corresponding type of signal source, the signal source data to be distributed of other types of signal sources cannot be affected, and the independence between the signal source data to be distributed of the different types of signal sources is ensured.

In an alternative embodiment, fig. 8 shows a flowchart of an alternative playback end, and as can be seen from fig. 8, in the process of ending playback, first, invoking of the signal source worker thread is stopped, then, the signal source worker thread and the storage resource occupied by the signal source data to be distributed are released, and after the signal source worker thread and the storage resource are released, playback of the signal source data is ended.
Furthermore, in the process of replaying the signal source data, the replayed signal source data can be replayed to the positioning service interface of the terminal device, so that the upper layer service can replay the current scene by using the replayed signal source data for infinite times, and further the influence of a variable environment on the positioning result is avoided.
According to the above, the scheme provided by the application can record all signal source data used for positioning, namely record the environment where the signal source data is located at that time, then select a signal source to be played back from the recorded multiple signal sources, and then play back the selected signal source data to be played back according to the recording sequence. The whole process does not need to consider the use scene of the upper-layer service, the data playback of the full-scene signal source can be carried out, and the application scene is wider.
