Detailed Description

The terminology used in the description of the embodiments section of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the present application.

Therefore, the track playback method, the track playback system and the electronic device are provided, the driving track of the vehicle can be marked, so that abnormal conditions in the driving process of the vehicle are highlighted, and the user experience is improved.

In this embodiment, the track playback method shown in fig. 1 is applied to a track playback system, the track playback system is connected to a vehicle-mounted terminal, the vehicle-mounted terminal is installed on a vehicle, the vehicle-mounted terminal acquires positioning information of the vehicle through a positioning module (such as GPS/beidou satellite positioning) when powered on, and then continuously sends the positioning information to the track playback system through a network (such as a 3G, 4G, or 5G network), for example, the vehicle-mounted terminal acquires current positioning information of the vehicle every 30 seconds and uploads the current positioning information to the track playback system. The track playback system is used for executing the track playback method and realizing the playback of the vehicle running track.

Considering that a network (such as a 4G network) is limited by various factors such as terrain, landform or high-rise buildings in the propagation process, or a vehicle runs to a relatively closed place, and the like, and the phenomena of poor or even interrupted network signals exist, so that the current positioning information of the vehicle cannot be uploaded or cannot be uploaded successfully, if the vehicle-mounted terminal is disconnected from the track playback system (the network signals are poor or interrupted, and the like), the vehicle-mounted terminal stores the positioning information which cannot be uploaded or cannot be uploaded successfully in the vehicle-mounted terminal or a vehicle memory, and after the vehicle-mounted terminal is in communication connection with the track playback system again, the vehicle-mounted terminal transmits the positioning information which cannot be uploaded or cannot be uploaded successfully to the track playback system.

In this embodiment, as shown in fig. 2, the track playback system may include a gateway, a message queue, a processing unit, and a playback device, which are electrically connected to each other to implement track playback.

The gateway is in communication connection with the vehicle-mounted terminal, and is used for receiving positioning information (such as first positioning information and second positioning information) sent by the vehicle-mounted terminal and sending the first positioning information and the second positioning information to the message queue. After receiving the positioning information (or data packet) reported by the vehicle-mounted terminal, the gateway analyzes the positioning information (or data packet) according to a specific data transmission protocol, for example, the positioning information is identified by 16-system bits, and the data transmission protocol defines the data content represented by different 16-system bits, including a reporting instruction ID corresponding to the data packet, a specific data field value and the like. The parsed positioning information (or data packet) format is encapsulated according to a gateway and processing unit protocol format, such as JSON format, and a field in the positioning information may include vehicle identification such as license plate number, serial number, ID (deviceId, string type), whether the positioning information is supplementary transmission data (real, string type), communication time (string type), vehicle acc state (accStatus, int type), positioning time (date time, string type), direction (direction, int type), latitude (latitude, double type), longitude (longitude, double type), speed (speed, double type), satellite number (stars, int type), mileage (mileage, double type), oil (double type), voltage (double type), engine speed (engine type, int type), engine temperature (engine temperature, double type), intake air (intake air time, intake air temperature, intake air equipment (intake air equipment), string type), and ignition time such as last ignition time (last ignition time, double type), etc., and the fields in the analyzed positioning information are protocol fields.

And the message queue is used for storing the first positioning information and the second positioning information sent by the gateway. Because the positioning information of the vehicle-mounted terminal is reported frequently, and when the number of the vehicle-mounted terminals is large, the requirement on the concurrent processing performance of the processing unit is high, the gateway sends the positioning information of the vehicle-mounted terminal to the message queue, the data queue waits for processing, and the positioning information of the vehicle-mounted terminal is obtained from the message queue according to the actual consumption capacity of the processing unit and is processed, so that the processing pressure of the processing unit is relieved. In addition, the message queue can store data in a certain period in a persistent mode, even if the processing unit goes down or has other faults, the unprocessed data in the message queue cannot be lost, and after the processing unit is recovered to be normal, the processing unit can continue to process the data from the break point, so that data loss is avoided. Preferably, the message queue may include middleware such as Kafka, RabbitMQ, ActiveMQ, and the like.

And the processing unit is used for acquiring the first positioning information and the second positioning information from the message queue, executing a track playback method and outputting the running track of the vehicle to a playback device.

Further, the track playback system may further include a non-relational database and a relational database, the track playback system further includes a non-relational database and a relational database, the non-relational database is configured to store the first positioning information and the second positioning information, and the relational database is configured to store the driving track of the vehicle.

Specifically, the processing unit periodically acquires the reported positioning information through message queuing and stores the reported positioning information into the non-relational database. Because the reporting frequency of the positioning information is high and the data volume is large, compared with a relational database, the embodiment of the invention adopts a non-relational database to store the positioning information, and has the advantages of high read-write performance, strong horizontal expansion capability of data stored in a Key-Value form, no upper limit of a storage space and the like, and the non-relational database is, for example, MongoDB and the like. Because the traveling track of the vehicle has strong relevance with the service (for example, the user can play back the traveling track of the specified vehicle, etc.), and the data format is fixed, a relational database is selected to store the traveling track of the vehicle, such as Mysql, Oracle, etc.

Playback means for playing back a travel locus of the vehicle. For example, the playback device is, for example, a browser having a track playback function, and the user may select a specified vehicle (such as a license plate number), a start time, an end time, or whether to display the additional transmission positioning information, and the like on the browser, request the corresponding vehicle travel track from the processing unit through the playback device according to the interface protocol, query the corresponding vehicle travel track from the relational database by the processing unit, and feed the corresponding vehicle travel track back to the playback device, and the playback device displays the travel track of the vehicle on the map by using the map interface. The interface protocol may be in JSON format, and the data field includes track start longitude (startLon, double type), end longitude (endLon, double type), start latitude (startLat, double type), end latitude (endLat, double type), track start time (startTime, string type), track end time (endTime, string type), vehicle stop duration (stoptime len, string type), track accumulated mileage (trackKm, double type), track accumulated duration (runtime len, string type), and the like.

Further, the playback device may have a function of playing the travel track of the vehicle to realize track playback control. The playback device can adopt the playing progress bar to perform track playback control, if a user clicks a playing button of the playing progress bar, the track playback control is dynamically displayed in a browser map, the vehicle can sequentially perform track running playback along the positioning position, the user can click a pause button to pause the playing at any time, and meanwhile, the playing progress bar can be dragged to perform skip playing or perform playing speed doubling adjustment, such as accelerated playing or decelerated playing and the like. Further, while the track is played back, the playback device displays the positioning information played back at the current moment, such as the unit where the vehicle is located, the license plate number, the driving speed, the ACC state, the positioning time, and the like. The dynamic display of the track playback can be realized through a map interface, the playing progress control can be realized by calculating the number of the positioning positions to evenly distribute the progress bars, and along with the track playback progress, the running track of the vehicle can be rendered to the current playback positioning position in the map in real time, so that a user can have good watching experience.

Further, the track playback method executed by the processing unit specifically refers to the track playback method of the method embodiment shown in fig. 1.

Fig. 1 is a flowchart of an embodiment of a track playback method of the present application, and as shown in fig. 1, the track playback method may include:

s101, obtaining a plurality of pieces of positioning information sent by the vehicle-mounted terminal, wherein the plurality of pieces of positioning information comprise a plurality of pieces of first positioning information and a plurality of pieces of second positioning information, the first positioning information comprises a supplementary transmission identifier, and the supplementary transmission identifier is used for identifying that the first positioning information is supplementary transmission data.

Preferably, the first positioning information includes a first position and a first positioning time of the vehicle during the communication connection between the vehicle-mounted terminal and the track playback system, and the second positioning information includes a second position and a second positioning time of the vehicle during the disconnection between the vehicle-mounted terminal and the track playback system.

That is to say, in the process of disconnecting the vehicle-mounted terminal from the track playback system, the vehicle-mounted terminal cannot upload the current positioning information (first positioning information) to the track playback system, the vehicle-mounted terminal stores the current positioning information (first positioning information) in the vehicle-mounted terminal or a vehicle memory, and after the vehicle-mounted terminal is in communication connection with the track playback system again, the vehicle-mounted terminal transmits the first positioning information stored in the memory to the track playback system again. The first positioning information comprises a supplementary transmission identifier, and the supplementary transmission identifier is used for identifying the first positioning information as supplementary transmission data. That is, the first positioning information is supplementary transmission data, which may be used to indicate a first position, such as longitude, latitude, or geographic coordinates, where the vehicle is located at the first positioning time.

In the normal communication process between the vehicle-mounted terminal and the track playback system, the vehicle-mounted terminal may upload the current positioning information (second positioning information) to the track playback system once every certain period of time (e.g., every 30 seconds). Therefore, during normal communication, the track playback system may receive the second positioning information transmitted by the in-vehicle terminal at regular intervals. Accordingly, the second positioning information may include a normal identifier, where the normal identifier is used to identify that the second positioning information is non-supplementary transmission data, that is, the second positioning information is non-supplementary transmission data, which may be used to indicate a second position, such as longitude, latitude, or geographic coordinates, where the vehicle is located at the second positioning time.

It should be understood that, in the process of retransmitting the first positioning information (retransmission data), to avoid collision with the reporting of the second positioning information (non-retransmission data), the vehicle-mounted terminal may interleave the plurality of first positioning information during the reporting of the second positioning information (e.g., in a time period between the reporting times of the plurality of second positioning information) according to the sequence of the positioning time to report.

And S102, generating a running track of the vehicle based on the plurality of first positioning information and the plurality of second positioning information.

Specifically, the first position and the second position are sequentially connected according to the sequence of the first positioning time and the second positioning time to obtain the driving track of the vehicle. For example, in a map, according to the sequence of positioning time, adjacent positions (e.g., between a plurality of first positions, between a plurality of second positions, and between a first position and a second position) may be connected by a straight line to form a driving track of a vehicle.

That is, the driving track of the vehicle may include a connection line between a plurality of positions, such as a connection line between a plurality of first positions, a connection line between a plurality of second positions, a connection line between a first position and a second position, and the like.

In one possible implementation manner, the driving trajectory of the vehicle includes a first driving trajectory, and step S103 may include:

s201, acquiring a plurality of pieces of first positioning information and a plurality of pieces of second positioning information within a first positioning duration every preset first duration, wherein the first positioning duration is determined according to the acquired current time;

s202, generating the first running track based on the plurality of first positioning information and the plurality of second positioning information within the first positioning time length.

For example, the preset first time period may be preset according to an actual application, for example, the preset first time period is 3 hours. The first positioning duration is a preset first time period before the current time, and the preset first time period may be preset according to an actual application condition, for example, the preset first time period is 12 hours or 24 hours. That is, every 3 hours, a plurality of first positioning information and a plurality of second positioning information of which the positioning time is within the current 12 hours or 24 hours and the like are obtained from the non-relational database, and the first driving track is obtained through calculation, so that the real-time performance of track playback is ensured.

In one possible implementation manner, the driving trajectory of the vehicle further includes a second driving trajectory, and step S103 further includes:

s301, acquiring a plurality of pieces of first positioning information and a plurality of pieces of second positioning information within a second positioning duration every preset second duration, wherein the second positioning duration is determined according to the acquired current time;

s302, generating a second driving track based on a plurality of pieces of second positioning information within the second positioning duration and a plurality of pieces of second positioning information;

In consideration of the situation that the positioning information is retransmitted, the preset second time period may be preset according to the actual application situation, for example, the preset second time period is 12 hours, the second positioning time period is a preset second time period before the current time, and the preset second time period may be preset according to the actual application situation, for example, the preset second time period is 24 hours or 48 hours. That is, every 12 hours, a plurality of first positioning information and a plurality of second positioning information of which the positioning time is within the current 24 hours or 48 hours are obtained from the non-relational database, and a second driving track is calculated, so that the accuracy of track playback is improved.

It should be noted that, for the same vehicle and the same time period, the playback device may perform track playback according to the second travel track, or the playback device may perform track playback according to the first travel track and the second travel track, respectively, so as to achieve the effect of mutual comparison.

In one possible implementation manner, the driving trajectory of the vehicle includes a plurality of segmented trajectories, and step S103 may include:

s401, acquiring a plurality of segmentation points, wherein the segmentation points comprise at least one of preset time points and moments when the vehicle is shut down or started;

s402, connecting the plurality of first positions and the plurality of second positions in each adjacent segmentation point according to the sequence of the first positioning time and the second positioning time to obtain a plurality of segmentation tracks.

Because the order of magnitude of the positioning information can reach hundreds of millions or even billions generally along with the time, the data volume is huge, and the track playback can not only display the visual vehicle running track, but also display the related information of each running track, such as the vehicle running mileage, the running time, the vehicle flameout information (such as the flameout time, the flameout time and the like), and the like. In order to improve the user experience and reduce the processing pressure of the processing unit, track segmentation calculation can be performed on the historical positioning information to obtain a plurality of segmented tracks.

For example, the preset time point is 24 points per day, and the trajectory segmentation is performed as long as any one of segmentation conditions or segmentation points such as "24 points per day" or "vehicle is turned off or started" is met. Therefore, a segment track can be obtained according to the first positioning information and the second positioning information in each adjacent segment point.

The segmented trajectory may include, but is not limited to, a start time, an end time, a flameout duration, a start location longitude and latitude, an end location longitude and latitude, an accumulated mileage, an accumulated driving duration, etc. of the segmented trajectory.

Further, in combination with the above steps S201, S202, S301, S302, S401 and S402, the first travel track may include a plurality of first segment tracks, the second travel track may include a plurality of second segment tracks, and the step S103 may further include: acquiring a plurality of first positioning information and a plurality of second positioning information within a first positioning duration every preset first duration, and performing track segmentation (refer to steps S401 to S402) to obtain a plurality of first segmented tracks; and acquiring a plurality of first positioning information and a plurality of second positioning information within a second positioning duration every preset second duration (refer to steps S401 to S402), and performing track segmentation to obtain a plurality of second segmented tracks.

It can be understood that each segmented track has strong association with a service, and the data format is fixed, and can be stored in a relational database, so that a user can conveniently perform track playback on the segmented track according to query conditions, user experience is improved, and processing pressure of a processing unit is reduced.

And S103, marking the running track of the vehicle based on the supplementary transmission identifier.

That is, by indicating a part of the traveling track of the vehicle, an abnormal situation of the vehicle during traveling is highlighted. For example, according to the supplementary transmission identifier, a supplementary transmission track section (for example, a track section obtained from the first positioning information) in the vehicle driving track is marked so as to highlight abnormal conditions such as data supplementary transmission and the like occurring in the driving process of the vehicle.

In one possible implementation manner, step S103 may include:

s501, marking a plurality of first positions in the running track of the vehicle, wherein the supplementary transmission marks correspond to the first positions.

That is to say, the supplementary transmission identifier in the first positioning information can be used to identify the first position as the positioning position of the supplementary transmission of the vehicle-mounted terminal. Therefore, according to the supplementary transmission identifier, which positions in the vehicle driving track are the first positions (namely, the supplementary transmission positioning positions) can be determined, and the plurality of first positions are marked by adopting a color or dotting mode (for example, a plurality of position points are added in the vehicle driving track) and the like, so that the abnormal conditions of the supplementary transmission positioning positions and the like in the vehicle driving track are prompted to a user, and the phenomena of poor communication quality or signal interruption and the like when the vehicle drives through the supplementary transmission positioning positions are prompted to the user.

In one possible implementation manner, the driving track of the vehicle includes a connection line between a plurality of the first positions, and step S103 may include:

and S502, marking connecting lines among the first positions.

For example, according to the supplementary transmission identifier and the first position in the first positioning information, a connection line between a plurality of first positions in the vehicle driving track is determined, and the connection line between the plurality of first positions (such as the supplementary transmission track in the map shown in fig. 3) is marked in rendering modes such as colors and the like, so as to distinguish other connection lines (or track segments) and play a role of prompting a user. That is, the connecting lines between the plurality of first positions are used for representing the supplementary transmission track segment obtained according to the supplementary transmission data (first positioning information), so that which driving track is the supplementary transmission track segment is intuitively displayed in the track playback process, and the user is prompted that the communication quality is poor or the signal is interrupted when the vehicle drives through the supplementary transmission track.

In one possible implementation manner, the method may further include:

s601, judging whether the distance between two adjacent positions in the driving track of the vehicle is larger than a preset threshold value or not;

and S602, if the distance between two adjacent positions in the driving track of the vehicle is greater than the preset threshold value, marking a connecting line between the two adjacent positions.

Under normal conditions, the reporting time interval of the positioning information (such as the interval between adjacent positioning moments) is short, so that the distance between adjacent positioning positions is short, and the connecting line between adjacent positioning positions is short, therefore, the output vehicle running track should be smooth. However, if a track abnormal condition (such as a data transmission link problem or a human problem) occurs, a distance (e.g., a linear distance) between adjacent positioning positions may be greater than a preset threshold, and the track abnormal condition is often a condition that a user needs to pay attention to, so to highlight the track abnormal condition, if a distance between two adjacent positions (e.g., a distance between two adjacent first positions, a distance between two adjacent second positions, or a distance between two adjacent first positions and second positions) is greater than the preset threshold, a connection line (e.g., an abnormal track in a map shown in fig. 4) between the two adjacent positions is marked by using a rendering method such as color, so as to distinguish other connection lines, and start an action of warning the user.

In one possible implementation manner, the positioning information further includes a location and a time when the plurality of vehicles are turned off or started, and the method may further include:

and S701, marking a plurality of positions where the vehicle is shut down or started in a running track of the vehicle according to the sequence of the time when the vehicle is shut down or started.

Specifically, the first positioning information or the second positioning information may include a flameout or start position and a time of the vehicle, and in a driving track of the vehicle, a flameout or start position (such as a flameout serial number in a map shown in fig. 5) of each vehicle is marked according to a rendering manner such as a sampling digital serial number and a sequence of the flameout or start time of the vehicle, so as to show the flameout or start position, the flameout or start time, flameout duration and other information of the vehicle in the driving track, thereby facilitating vehicle management.

And S104, outputting the marked running track of the vehicle.

That is to say, the driving track of the vehicle may be displayed on a map, and the connecting lines between the first positions after the indication, the abnormal track after the indication, and/or the flameout or start positions of the vehicle after the indication may be displayed on the map, so as to highlight the abnormal situation occurring during the driving process of the vehicle.

Further, the track playback system may further include a user query unit, configured to receive query information input by a user, such as a license plate number, a start time, an end time, and the like, and according to the query information, the processing unit retrieves a corresponding vehicle travel track (or segment track) from the relational database, and outputs the vehicle travel track (or segment track) to the playback device, and the playback device performs playback.

It can be understood that, if the output vehicle driving track includes a plurality of segment tracks, the playback device can display each segment track in a list manner, so that a user can select any one segment track to play.

Furthermore, the query information input by the user may further include whether to display the supplementary transmission track, and if so, the connection lines between the marked first positions are displayed in the map so as to highlight the supplementary transmission track segment for the user to check.

It is to be understood that some or all of the steps or operations in the above-described embodiments are merely examples, and other operations or variations of various operations may be performed by the embodiments of the present application. Further, the various steps may be performed in a different order presented in the above-described embodiments, and it is possible that not all of the operations in the above-described embodiments are performed.

It should be understood that the above division of the modules of the track playback system 100 shown in fig. 2 is only a logical division, and the actual implementation may be wholly or partially integrated into one physical entity or may be physically separated. And these modules can be realized in the form of software called by processing element; or may be implemented entirely in hardware; and part of the modules can be realized in the form of calling by the processing element in software, and part of the modules can be realized in the form of hardware. For example, the processing unit may be a separate processing element, or may be integrated into a chip of the electronic device. Other modules are implemented similarly. In addition, all or part of the modules can be integrated together or can be independently realized.
