Detailed Description
In order to solve the problem that in the prior art, the running track of a vehicle terminal is drawn as a fold line through positioning data collected by a positioning device on the vehicle terminal and is not attached to the trend of an actual road surface, the embodiment of the application provides a track information processing method.
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
Fig. 1 is a schematic flow chart of a trajectory information processing method provided in an embodiment of the present application, and as shown in fig. 1, the method is applied to a transportation platform server, where the transportation platform server is in communication connection with a vehicle terminal, and the method includes:
step 101: the method comprises the steps of obtaining effective track information of a vehicle terminal, wherein the effective track information comprises a plurality of effective positioning data and time information corresponding to each effective positioning data.
The vehicle terminal can be a vehicle-mounted terminal, or a mobile terminal used by a driver driving a vehicle, specifically, a mobile phone, a tablet computer, a smart watch and the like, as long as the positioning function can be realized, and the vehicle terminal can be in communication connection with the transportation platform server. The effective track information is a track drawn by a plurality of effective positioning data. The effective positioning data is obtained by extracting the effective positioning data reported by the vehicle terminal from the transportation platform server in advance and is stored in a storage medium, each effective positioning data also has corresponding time information, and the time information is the time corresponding to the vehicle terminal when the effective positioning data is collected.
Step 102: and equally dividing the distance of the effective track information to obtain a plurality of equally divided distance sections.
In a specific implementation process, after obtaining the effective track information, the transportation platform server may equally divide the effective track information according to a preset number of segments, or equally divide the effective track information according to a preset distance.
Step 103: and determining the effective positioning data of the target from the effective positioning data contained in each equal-division distance segment as the effective equal-division points of the corresponding equal-division distance segment.
After the transportation platform server obtains a plurality of equal-division distance sections, because each equal-division distance section comprises a plurality of effective positioning data, in order to ensure the accurate basis of the track, the calculation pressure of the map server is reduced, and one target effective positioning data can be determined from each equal-division distance section and is used as an effective equal-division point of the equal-division distance section. Of course, two effective object location data may also be determined from the equal division distance segment, and the number of the specific effective object location data may be preset according to an actual situation, which is not specifically limited in the embodiment of the present application.
Step 104: sending an interval point set to a map server so that the map server can obtain incremental route points according to the interval point set; wherein the set of interval points comprises effective positioning data with earliest time information, effective positioning data with latest time information and the effective equal division points.
After determining the effective object location data corresponding to each equal-division distance segment, the transportation platform server sends all the effective object location data as a set of interval points to the map server, and it can be understood that the map server can be a high-resolution map server or a Baidu map server. And after receiving the interval point set, the map server matches the actual running track route of the vehicle terminal according to the effective equal division points in the interval point set. After the actual running track route is determined, inserting a preset number of route points in the track route between two adjacent effective equally dividing points to obtain incremental route points. It will be appreciated that incremental route points include route points and efficient bisection points inserted by the map server. The map server asynchronously pulls route points through mq.
Step 105: and receiving and storing the incremental route points sent by the map server.
After obtaining the incremental route point, the map server sends the incremental route point to the transportation platform server, and the transportation platform server stores the received incremental route point in a storage medium, where the storage medium may be a database.
According to the embodiment of the application, the effective equal division points are determined from the received effective track information, and the interval point set containing the effective equal division points is sent to the map server, so that the map server increases the positioning points of the actual route in the map according to the effective equal division points, the incremental route points are obtained, and the vehicle running track drawn through the incremental route points is more fit with the actual route.
On the basis of the above embodiment, the determining, from the effective location data included in each equally-divided distance segment, the target effective location data as the effective equally-divided point of the corresponding equally-divided distance includes:
determining a midpoint in the equally spaced segments;
and taking the effective positioning data closest to the intermediate point as the effective equally dividing point corresponding to the equally dividing distance segment.
In a specific implementation process, the transportation platform server equally divides each equally-divided distance section into two sections, and the division point is the middle point. And taking the effective positioning data closest to the middle point as an effective equally dividing point of the equally dividing distance. Fig. 2 is a schematic diagram of determining effective bisectors according to an embodiment of the present application, and as shown in fig. 2, open circles represent effective positioning data in the bisector segments, and filled circles represent middle points in the bisector segments. The distance between effective positioning data A and the intermediate point O is 10 meters, the distance between effective positioning data B and the intermediate point O is 8 meters, the distance between effective positioning data C and the intermediate point O is 5.4 meters, the distance between effective positioning data D and the intermediate point O is 2.2 meters, the distance between effective positioning data E and the intermediate point O is 4 meters, the distance between effective positioning data F and the intermediate point O is 6 meters, and the distance between effective positioning data G and the intermediate point O is 10.3 meters. Since the effective positioning data D has the shortest distance to the intermediate point O, the effective positioning data D is used as the effective distance of the equal division distance segment.
The embodiment of the application takes the middle point of each equal division distance segment as the effective equal division point, so that the obtained effective equal division points are distributed uniformly, and the accuracy of the vehicle track is improved.
On the basis of the above embodiment, the acquiring effective track information of the vehicle terminal includes:
acquiring current position information of the vehicle terminal;
judging whether the distance between the vehicle terminal and a loading place or a unloading place is smaller than a preset distance according to the current position information;
if the effective track information is smaller than the preset distance, acquiring the effective track information according to a first preset time period; otherwise, acquiring the effective track information according to a second preset time period; wherein the first preset time period is less than the second preset time period.
In a specific implementation process, the vehicle terminal sends positioning data collected in a preset time interval to the transportation platform server according to the preset time interval, after the transportation platform server obtains the positioning data, the current position information of the vehicle terminal is obtained from the positioning data, whether the distance between the vehicle terminal and a loading place is smaller than a preset distance or whether the distance between the vehicle terminal and the loading place is smaller than the preset distance is judged based on the current position information, it can be understood that the distance between the current position information and the loading place or the unloading place can be a straight line distance or an actual driving distance, and the preset distance is a preset distance, for example: may be 10 km, 20 km, etc. If the distance is less than the preset distance, it indicates that the vehicle terminal is near the loading place or the unloading place, and at this time, the transportation platform server may obtain valid trajectory information once every first preset time period, for example: may be taken every 5 minutes, may be taken once every 6 minutes, and so on. If the distance is not less than the preset distance, it indicates that the vehicle terminal is far away from the loading place or the unloading place, and the transportation platform server may obtain valid trajectory information once every second preset time period, for example: the acquisition may be performed every 10 minutes, or may be performed every 15 minutes. In summary, the first preset time period is smaller than the second preset time period.
In the embodiment of the application, when the vehicle terminal is determined to be close to the loading and unloading places, the vehicle terminal is controlled to report the effective track information frequently, and when the vehicle terminal is determined to be close to the loading and unloading places, the effective track information is obtained to be lengthened at intervals, so that the consumption of flow can be effectively reduced.
On the basis of the above embodiment, the method further includes:
receiving a track checking request sent by a goods owner terminal, wherein the track checking request comprises order information;
inquiring corresponding order state according to the order information;
if the order state is finished, acquiring a full increment line point corresponding to the order information from a storage medium;
and sending the full increment route point to a goods owner terminal corresponding to the vehicle terminal so that the goods owner terminal displays the running track of the vehicle terminal according to the full increment route point.
In a specific implementation process, a shipper can check the driving track of a vehicle terminal in real time through a shipper terminal, and when the driving track needs to be checked, a track checking request is sent to a transportation platform server through the shipper terminal. After receiving the track check request, the transportation platform server extracts order information in the track check request, where the order information may be an order number. The corresponding order status is queried according to the order information, and it can be understood that the order status may be completed or incomplete. In the case of a completed order status, the storage medium of the transport platform server stores the complete incremental route points of the vehicle terminal from the loading site to the unloading site, i.e., the full incremental route points. The transportation platform server returns the complete incremental route points to the goods owner terminal, and the goods owner terminal maps the incremental route points on the map after receiving the incremental route points, so that the driving track of the vehicle terminal can be displayed for the goods owner.
For the case that the order status is incomplete, the storage medium of the transportation platform server stores incremental route points obtained by the vehicle terminal from the beginning to the last time, such as: the transportation platform server receives the track viewing request at 11/9/10/12 in 2021, the last acquired incremental route point stored in the storage medium is 10/00 at 11/9/2021, and then the incremental route points between 10/00 and 10/12 are absent from the storage medium. The transportation platform server obtains the positioning data of the time period from the vehicle terminal, and extracts effective positioning data according to the positioning data, and it can be understood that the extraction of the effective positioning data is described in the following embodiments. After the effective positioning data is extracted, the incremental line points of 10:00-10:12 are obtained according to the method for obtaining the incremental line points according to the effective positioning data in the embodiment. And then, the transportation platform server sends the incremental route points acquired from the database and the incremental route points of 10:00-10:12 to the cargo owner terminal together so as to display the driving track of the vehicle terminal on the cargo owner terminal.
According to the method and the device for checking the vehicle terminal, after the track checking request is received, if the order state is finished, all the driving tracks of the vehicle terminal corresponding to the order are sent to the goods owner terminal, if the order state is not finished, the stored incremental line points are obtained from the storage medium, and the nearest incremental line points are obtained from the map server, so that the goods owner can know the driving route information of the vehicle terminal.
On the basis of the above embodiment, before obtaining the effective trajectory information of the vehicle terminal, the method further includes:
sending a track acquisition instruction to a vehicle terminal according to a third preset time period, so that the vehicle terminal acquires track information in the third preset time period after receiving the track acquisition instruction;
receiving the track information; wherein the trajectory information comprises a plurality of positioning data;
performing rarefaction processing on the plurality of positioning data to obtain effective positioning data;
and storing the effective positioning data into a storage medium.
In a specific implementation process, as shown in fig. 3, a delay queue is created in advance in a transportation platform server, where the delay queue includes a timer, and the timer is triggered every third preset time period, so that the delay queue sends a message to an integrating process in the transportation platform server, where the state of an order is monitored, and after receiving the message, the integrating process checks whether the order is in fulfillment, that is, whether the order is completed, and if not, sends a track pulling message to an order-position-service in the transportation platform server, where the order-position-service is used to obtain a track of a vehicle, and after receiving the message, the order-position-service sends a track obtaining instruction to a vehicle terminal. After receiving the track acquisition instruction, the vehicle terminal preferentially pulls the Beidou positioning data, and if the Beidou positioning data is successfully pulled, the Beidou positioning data is returned to the order-position-service; and if the Beidou positioning data is not successfully pulled, pulling the GPS positioning data, and returning the GPS positioning data to the order-position-service.
It should be noted that the third preset time period may be dynamically changed according to the driving position of the vehicle terminal, for example: the vehicle terminal is close to a loading place or a vicinity of a discharging place, the third preset time period can be 5 minutes, 6 minutes and the like, the vehicle terminal runs between the loading place and the discharging place, the third preset time period can be 10 minutes, 15 minutes and the like, and the purpose of the method is to achieve refined display of the positioning data when the vehicle terminal is close to the loading place and the discharging place, improve the positioning accuracy near the loading place and the discharging place, and prolong the interaction times of the vehicle terminal and the transportation platform server when the vehicle terminal is close to the loading place and the discharging place, so that the consumption of the flow of the vehicle terminal is reduced.
It is understood that, when the vehicle terminal returns the track information to the transportation platform server, each time the track information is returned within the third preset time period.
After receiving the track information, the order-position-service performs rarefaction processing on a plurality of positioning data in the track information, and the purpose of rarefaction processing on the positioning data is to reduce excessively dense positioning data and eliminate abnormal positioning data. Therefore, effective positioning data capable of representing the driving track of the vehicle terminal is reasonably reserved. After the effective positioning data is stored, the message of successfully pulling the positioning data is returned to the delay queue through the ingoing process. The delay queue records the result and times it back.
It should be noted that, if the vehicle terminal reaches the last unloading place for the preset time period, the update trajectory is not pulled, and the update trajectory state is the trajectory completion state.
On the basis of the foregoing embodiment, the performing rarefaction processing on the plurality of positioning data to obtain effective positioning data includes:
performing rarefaction on the plurality of positioning data according to a preset time interval or a preset distance interval to obtain rarefaction data;
obtaining two adjacent rarefying data P from the rarefying dataiAnd PjAccording to PiAnd PjThe distance and time therebetween, calculating the traveling speed of the vehicle, and if the traveling speed is greater than a preset speed, determining PjTo be abnormal, P is addedjAnd removing the effective positioning data.
In a specific implementation process, after acquiring the plurality of positioning data returned by the vehicle terminal, the transportation platform server performs thinning on the plurality of positioning data according to a preset time interval (e.g., 10 minutes) or a preset distance interval (e.g., 30 meters). With the preset time interval of 10 minutes, the time corresponding to the plurality of positioning data is 11/9/12/2021/11/9/11/13/2021/11/9/14/2021/11/9/16/2021/11/9/11/19/2021/11/9/21/2021/11/9/11/25 as an example, the positioning data corresponding to 11/9/11/12/2021/11/22 should be the first data to be extracted, and the next data to be extracted should be the positioning data after 11/9/11/22/2021/11/9, that is, the positioning data corresponding to 11/9/25/2021/and so on. It is understood that the method of performing thinning at the preset distance interval is similar to the method of performing thinning at the preset time interval, and will not be described herein again. In addition, specific values of the preset time interval and the preset distance interval may be set according to actual conditions, and this is not specifically limited in the embodiment of the present application.
It should be noted that, during the rarefying, it is necessary to determine the effective positioning data that is first rarefied out, and the determination method may be: and taking the first reported positioning data within a preset range from a loading place as first rarefying data.
After obtaining the rarefaction data through rarefaction, carrying out abnormal point elimination on the rarefaction data again, wherein the specific method comprises the following steps: according to the time sequence, the following operations are carried out on any two adjacent positioning data in the rarefied data: and acquiring the distance and the time in two adjacent rarefaction data, calculating the running speed of the vehicle according to the distance and the time, and if the running speed is greater than a preset speed, indicating that one of the two rarefaction data is an abnormal point. And in two adjacent rarefaction data, the rarefaction data which is earlier in time is verified through the previous round, so that the rarefaction data which is later in time is considered as an abnormal point. And eliminating abnormal points in the rarefied data to obtain effective positioning data.
According to the method and the device, effective positioning data are obtained by performing rarefaction and abnormal point elimination on the plurality of positioning data.
