Detailed Description
To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Fig. 1 shows an architecture to which a notification information transmission method of embodiments of the present invention is applied. As shown in FIG. 1, the architecture includes: a vehicle platform 1, the internet 2, a notification information transmitting device 3, and a user terminal 4. The vehicle platform 1 is respectively connected with the notification information sending device 3 and the user terminal 4 in a communication mode through the internet 2, the notification information sending device 3 is also connected with the user terminal 4 in a communication mode through the internet, each notification information sending device 3 is installed on one vehicle, and each user terminal 4 is associated with one user.
The carrier vehicle platform 1 is the hosting platform for the service. The user may obtain the access permission of the vehicle platform 1 by means of registration or the like, and then access the vehicle platform 1 through the user terminal 4 to send a service request to the vehicle platform 1. The vehicle platform 1, upon receiving the service request, generates a service command according to the service request, and transmits the service command to the service execution tool. The vehicle, which is a service execution means of the vehicle platform 1, travels to the meeting and location upon receiving the service command, and transmits notification information to the user terminal 4 through the notification information transmitting device 3 mounted thereon to notify the user to drive to the meeting and location. The vehicle may then deliver the service to the user at the meeting and location and after the vehicle meets and meets.
The vehicle and the user may be different according to different application scenarios. For example, in a delivery scenario for courier or takeaway, the delivery vehicle is an item delivery vehicle and the user is a pickup. For another example, in a scenario where a network reservation is received from a passenger, the vehicle is a network reservation and the user is a passenger. For another example, in a scenario where a company's commuter vehicle receives a company employee, the delivery vehicle is the commuter vehicle and the user is the employee. It should be understood that specific scenarios to which the notification information sending method according to the embodiments of the present invention is applicable include, but are not limited to, the three scenarios described above.
The notification information sending device 3 sends the notification information according to the notification information sending method according to the embodiments of the present invention. It should be noted that, if the departure positions of the vehicle and the user are the same, the vehicle can directly deliver the service to the user, and the notification information transmitting device 3 does not need to execute the notification information transmitting method to transmit the notification information.
The notification information transmission method performed by the notification information transmission apparatus 3 is described in detail below based on an embodiment.
The first embodiment is as follows:
the notification information sending method provided by the present embodiment is shown in fig. 2. Referring to fig. 2, the notification information transmission apparatus 3 executes a notification information transmission method including:
step S101, the meeting and the position of the user and the vehicle are obtained.
It should be noted that the meeting and location as a location of the meeting between the user and the vehicle is different from both the departure location of the vehicle and the departure location of the user.
Specifically, the meeting and location may be one location specified by the user, one location specified by the vehicle platform 1, or one location selected by the user from a plurality of locations provided by the vehicle platform 1. It should be understood that, regardless of the determination of the meeting and the location, the vehicle platform 1 additionally acquires the meeting and the location of the delivery service while receiving the service request, and thus the notification information sending device 3 can acquire the meeting and the location directly from the vehicle platform 1.
Step S102, predicting the time when the user arrives at the meeting and the position.
It should be noted that the time of arrival of the user at the meeting and the location is a concept of "duration", for example, 10 minutes.
It is emphasized that, unlike the prediction by human experience when the takeaway is delivered by the takeaway, the prediction of the time of arrival at the meeting and location of the user is an accurate estimation of the time advance of arrival at the meeting and location of the user by the notification information sending apparatus 3 based on specific data.
And step S103, determining to send notification information to the user according to the current position, the meeting and the position of the vehicle and the predicted time of the user reaching the meeting and the position.
Specifically, the notification information sending device 3 may have a plurality of data acquisition times arranged in chronological order according to a preset rule.
After the current position of the transport vehicle is collected at the current data collection time, the notification information sending device 3 judges whether the notification information can be sent to the user according to the current position, the meeting and the position of the transport vehicle and the predicted time of the user reaching the meeting and the position, wherein if the notification information can be sent to the user, the notification information is sent to the user and the current position corresponding to the transport vehicle at the later data collection time is not collected any more; and if the notification information cannot be sent to the user, repeating the step of the current data acquisition time at the next data acquisition time.
In the embodiment of the invention, because the time of the user reaching the meeting and the position not only is the time interval between the user reaching the meeting and the position after the notification information is sent, but also is the time interval reference time interval between the user reaching the meeting and the position after the notification information is sent, the time difference between the user reaching the meeting and the position can be accurately controlled by the vehicle by taking the time of the user reaching the meeting and the position as reference. Furthermore, the technical problem that the waiting time of any one of the delivery vehicle and the customer is long can be solved under the condition that the delivery vehicle is an express delivery vehicle or a takeaway delivery vehicle.
Example two:
the notification information sending method provided in this embodiment basically adopts the same steps as those in the first embodiment, and therefore, the description thereof is omitted.
The difference lies in that: step S102 of the first embodiment of the present invention is a method for predicting the time of arrival of a user at a meeting and a location, including: determining the times of arrival of the user at the meeting and the position from the user starting position in history; under the condition that the times are not less than a preset time threshold value, predicting the time of the user for arriving at the meeting and the position according to the time length of the user from the starting position to the meeting and the position in history; in the case where the number of times is less than the predetermined number-of-times threshold value, the time at which the user arrives at the meeting and location is predicted from the time length of arrival at the meeting and location from the user's departure location in the history of the user registered on the vehicle carrying platform 1. Specifically, referring to fig. 3, the implementing step may be to include:
step S1021, determining the times of arrival of the user at the meeting and position from the user departure position in history;
step S1022, determining whether the number of times is greater than a predetermined number of times threshold, wherein if the number of times is greater than the predetermined number of times threshold, step S1023 is executed, otherwise step S1024 is executed;
step S1023, according to the time length of arriving at the meeting and the position from the user starting position in the user history, predicting the time of arriving at the meeting and the position of the user;
step S1024, predicting the time when the user arrives at the meeting and the location based on the time length from the user' S departure location to the meeting and the location in the history of the user registered on the transportation vehicle platform 1.
For example, if the predetermined number threshold is 3:
if the number of times that the user Q historically arrives at the meeting and the position from the user starting position is 5, predicting the time that the user arrives at the meeting and the position according to the time length that the user Q historically arrives at the meeting and the position from the user starting position;
if the number of times that the user Q has historically arrived at the meeting and location from the user's departure location is 2, the time that the user arrived at the meeting and location is predicted based on the time length that the user has historically arrived at the meeting and location from the user's departure location registered on the transportation vehicle platform 1.
Specifically, the users registered on the vehicle platform 1 include both the user Q who needs to predict the arrival and location time and other users other than the user Q.
It should be noted that, regardless of the user Q or the user registered on the platform of the transportation vehicle, the "time length from the departure position to the meeting and position of the user in the history" may refer to a fixed length of time period in the history, or may refer to the entire history time period before the current time.
In the embodiment of the invention, under the condition that the times of arrival at the meeting and the position from the user departure position are less in history of the user Q, the time of arrival at the meeting and the position of the user is predicted according to the time length of arrival at the meeting and the position from the user departure position in history of the user Q registered on a carrying vehicle platform, so that the unfavorable guidance of some non-pervasive situations of the user Q on the prediction can be avoided; and under the condition that the times of arrival at the meeting and position from the user starting position are enough in the history of the user, the prediction duration close to the actual situation of the user Q can be obtained by simple operation depending on less data.
Example three:
the notification information sending method provided in this embodiment basically adopts the same steps as those in the above embodiments, and therefore, the details are not described again.
The difference lies in that: referring to fig. 4, step S1023, for predicting the time of arrival at the meeting and the location of the user according to the time length of arrival at the meeting and the location from the user' S departure location historically includes:
step S401, obtaining the starting position of the user;
step S402, acquiring the time length of the user from the user departure position to the meeting and position each time before the current time to obtain a plurality of time lengths corresponding to the user;
step S403, determining an average of a plurality of durations corresponding to the user as the time of the user reaching the meeting and the location predicted at the current time.
For example, if the plurality of time periods corresponding to the user Q are 3min, 5min, and 7min, the time when the user Q arrives at the meeting and the location is predicted to be 5 min.
Specifically, in step S402, the time length of the user from the user departure location to the meeting location each time before the current time is obtained may be: the method comprises the steps of recording the time length from the user departure position to the meeting and position of the user Q in each meeting and process of the carrying vehicle and the user Q in time after the meeting and the position of the carrying vehicle and the user Q are met, ensuring that the time length from the user departure position to the meeting and the position of the user Q in history is not neglected, and meanwhile, recording the time length as history data of the user Q at the later time, wherein the history data is a real-time update of a history data set related to the user Q used at the later time.
In the embodiment of the invention, the average of the time length of the user Q from the starting position of the user Q to the meeting and the position in each history is determined as the time of the user Q to the meeting and the position, which is beneficial to overcoming the influence of some accidental special conditions of the user Q (for example, the user arrives at the meeting and the position too fast due to accidental urgent follow-up matters, or the user arrives at the meeting and the position slowly due to accidental illness) on the prediction accuracy; moreover, the corresponding time length in the latest time period of the user Q has more reference to the time for predicting the current meeting and position of the user Q, and the time length corresponding to the latest time period of the user Q is taken into account, so that the predicted time for the user Q to reach the meeting and the position is more reasonable and accurate.
Example four:
the notification information sending method provided in this embodiment basically adopts the same steps as those in the above embodiments, and therefore, the details are not described again.
The difference lies in that: referring to fig. 5, the step S1024, predicting the time when the user arrives at the meeting and the location according to the time length of the user who is registered on the vehicle platform 1 and historically arrives at the meeting and the location from the user departure location, includes:
step S501, obtaining the starting position of the user;
step S502, acquiring the time length of the user registered on the platform of the carrier vehicle before the current time from the departure position to the meeting and meeting position of the user every time, and acquiring a plurality of time lengths corresponding to the platform of the carrier vehicle;
in step S503, an average of a plurality of time durations corresponding to the vehicle platform is determined as the time when the user arrives at the meeting and location.
For example, if the user registered on the vehicle platform historically arrives at the meeting and location from the user departure location for the time periods T1, T2, T3, T4, and T5, the predicted time T for the user Q to arrive at the meeting and location is (T1+ T2+ T3+ T4+ T5)/5.
It should be noted that the averaged durations correspond to durations of the vehicle platform, which may correspond to different numbers of users due to historical data of users on the vehicle platform, wherein the averaged durations may all correspond to one user, for example, t1, t2, t3, t4, and t5 all correspond to user a; it is also possible to correspond to a plurality of users, for example, t1 and t2 correspond to user a and t3, t4 and t5 correspond to user B, or t1 corresponds to user a, t2 corresponds to user B, t3 corresponds to user C, t4 corresponds to user D, and t5 corresponds to user E.
Specifically, in step S502, the time length of each arrival of the user at the meeting and location from the user departure location, which is registered on the transportation vehicle platform 1 before the current time, may be: after each meeting and meeting of each user on the carrying vehicle and the carrying vehicle platform 1, the time length from the departure position of the user Q to the meeting and the position of the user in the meeting and the process is recorded in time, so that the integrity of the historical data related to the carrying vehicle platform 1 at a later moment is ensured, and the historical data set related to the carrying vehicle platform 1 used at the later moment is updated in real time.
It should be appreciated that users other than user Q on the vehicle platform may also have reference to the current predicted time of arrival at the meeting and location for user Q because they still use the time of arrival at the meeting and location from their departure location from user Q, and thus have the same congestion factor as user Q faces in the public environment in terms of the time required to arrive at the meeting and location.
In the embodiment of the invention, the average of the time lengths of the users registered on the vehicle carrying platform 1 from the departure positions to the meetings and the positions at each time in history is determined and is used as the time of the users to the meetings and the positions, so that the adverse effects caused by various accidental special conditions on the vehicle carrying platform 1 are avoided through a large number of samples, the time lengths corresponding to the vehicle carrying platform 1 in the latest time period are more referential to the time for predicting the current meetings and the positions of the users, and the predicted time lengths corresponding to the latest time period on the vehicle carrying platform 1 are taken into account, so that the time for the users Q to arrive at the meetings and the positions is more accurate.
Example five:
the notification information sending method provided by the present embodiment is shown in fig. 6.
Specifically, the notification information sending method provided in this embodiment basically adopts the same steps as those in the first embodiment, and thus, the description thereof is omitted.
The difference lies in that: the time when the user arrives at the meeting and location includes a first time when the user goes down the stairs and a second time when the user arrives at the meeting and location from the downstairs, and referring to fig. 6, step S102, predicting the time when the user arrives at the meeting and location includes:
step S102a, determining a first time T according to the floor number of the user1。
Specifically, any one of the following schemes may be adopted:
scheme one, acquiring historical average time t required by user to land one layeraThen if the number of floors where the user is located is recorded as N, the first time T is1＝ta·(N-1)；
Scheme two, acquiring the time t historically required for a user to land from floor (i +1) to floor iiThen, if the number of floors where the user is located is recorded as N, the first time is
Step S102b, according to the navigation distance of the user from downstairs to meet and position and the user walking speed obtained from the historical record, determining the second time T2。
Specifically, if the navigation distance of the user from the downstairs to the meeting and the position is recorded as s, and the walking speed of the user obtained from the historical record is recorded as v, the second time T is2＝s/v。
Step S102c, determining a first time T1And a second time T2And T as the time of arrival of the user at the meeting and location.
In the embodiment of the invention, the time of the user arriving at the meeting and the position is divided into the first time of the user going downstairs and the second time of the user arriving at the meeting and the position from downstairs, the first time is determined by the floor number, and the second time is determined by the navigation distance of the user from downstairs to the meeting and the position and the walking speed of the user obtained from the historical record, so that the time of the user arriving at the meeting and the position is more finely calculated, and the predicted time of the user arriving at the meeting and the position is more accurate.
Example six:
the notification information sending method provided in this embodiment basically adopts the same steps as those in the first embodiment, and therefore, the description thereof is omitted.
The difference lies in that: step S103, determining to send notification information to the user according to the current position, the meeting and the position of the vehicle and the predicted time of the user reaching the meeting and the position, wherein the steps comprise:
planning a navigation route according to the current position, the meeting and the position of the carrier vehicle;
determining a current remaining distance of the vehicle to the meeting and location along the navigation route;
determining whether the message sending condition is met according to the target speed of the carrying vehicle in the current surplus distance, the current surplus distance and the predicted time of meeting and position of the user; and the number of the first and second groups,
and sending notification information to the user when the message sending condition is determined to be met.
In particular, the planning of the navigation route according to the current position of the vehicle and the meeting and the position may be by planning the navigation route from the current position of the vehicle to the meeting and the position on the navigation module. It is emphasized that the navigation route is the route that the vehicle actually will travel next.
It should be noted that, in the course of driving to a meeting and a location, the current location of the vehicle may be sampled once every time a sampling interval duration passes and it is determined whether the message sending condition is met, wherein, when it is determined that the message sending condition is not met, the above steps are repeated when a sampling interval duration passes again; and when the message sending condition is determined to be met, sending notification information to the user.
It is emphasized that the notification information is sent to the user when it is determined that the message sending condition is reached, i.e. the notification information is sent to the user while it is determined that the message sending condition is reached; and, it is determined whether the message transmission condition is reached immediately after the current position of the carrier vehicle is collected, so that the notification information is transmitted to the user once the message transmission condition is reached in the course of the travel of the carrier vehicle.
For example, the vehicle is at Tx1The time arrives at the meeting and the position from the self-departure place, and every time delta T passesxSampling the current position of the vehicle once in a time length if Tx1+(n·ΔTx) Time does not reach the message sending condition but is Tx1+(n·ΔTx+ΔTx) When the time reaches the sending condition, it is at Tx1+(n·ΔTx+ΔTx) And sending notification information to the user at any moment.
In the embodiment of the invention, the notification information is sent to the customer according to the current remaining length, and the current remaining length is the actual distance to be traveled by the carrier vehicle from the current position to the meeting and the position, so that compared with the prior art that the length of the interval from the current position to the meeting and the position (the length of the straight line between the current position and the meeting and the position) is determined to send the notification information to the customer, the time consumed for the carrier vehicle to arrive at the meeting and the place can be determined more accurately, and the time difference for the carrier vehicle and the user to arrive at the meeting and the position can be controlled accurately.
Example seven:
the notification information sending method provided in this embodiment basically adopts the same steps as those in the sixth embodiment, and therefore, the description is omitted.
The difference lies in that: the message transmission condition is preferably defined. Specifically, the message sending condition includes: the time T' for the current arrival of the vehicle at the meeting and location and the predicted user arrival time T at the meeting and location satisfy a predetermined time relationship, wherein,
the time T 'for the current arrival meeting and position of the carrier vehicle is determined according to the target speed V and the current remaining distance S';
the predetermined time relationship includes a time T' for the vehicle to currently arrive at the meeting and location being less than one of: predicted time T of user meeting and position, and first redundant time T0Predicted time of arrival and location of user T minus a second redundant time T00。
It should be understood that the predetermined time relationship includes: t'<T, or the predetermined time relationship comprises: t'<T+T0Or the predetermined time relationship comprises: t'<T+T0That is, the predetermined time relationship does not simultaneously include: t'<T、T'<T+T0And T'<T+T0。
Specifically, the notification information sending method provided by the present embodiment is shown in fig. 7. Referring to fig. 7, step S103, determining to send notification information to the user according to the current position, the meeting and the position of the vehicle and the predicted time of arrival and the position of the user, includes:
step S103a, planning a navigation route according to the current position and the meeting and the position of the vehicle. Specifically, the current position and meeting and position of the vehicle may be input to a navigation module installed on the vehicle, and then a navigation route planned by the navigation module may be acquired.
Step S103b, determining the current remaining distance S' for the vehicle to reach the meeting and location along the navigation route. It should be understood that the current remaining distance S' for the vehicle to reach the meeting and location along the navigation route is the length of the journey the vehicle will need to actually travel next.
Step S103c, determining the time T ' for the vehicle to arrive at the meeting and the location based on the target speed V of the vehicle within the current remaining distance S ' and the current remaining distance S '. Specifically, T '═ S'/V may be used.
Step S103d, if the determined time T' for the current arrival of the vehicle at the meeting and location and the predicted time T for the user to arrive at the meeting and location satisfy the predetermined time relationship, it is determined to transmit the notification information to the user.
It should be noted that the first redundant time T0Is a parameter that ensures that the vehicle does not need to wait (user needs to wait), and a second redundant time T00Is a parameter that ensures that the user does not have to wait (the vehicle needs to wait), and thus the first redundant time T0And a second redundant time T00All are small values, and the detailed values can be preset according to actual requirements.
It should be noted that:
(1) during the arrival of the carrier vehicle at the meeting and location along the navigation route, the remaining distance is collected at a plurality of preset times and the time T' is determined.
Based on this, it should be noted that, for any one of the predetermined time relationships described above, if the remaining distance is collected at the target time and the predetermined time relationship is determined to be satisfied, the notification information is transmitted and the remaining distance is not collected any more.
(2) During the arrival of the vehicle at the meeting and location along the navigation route, the remaining distance is continuously reduced with the travel of the vehicle, so that the determined time T 'is also continuously reduced with the travel of the vehicle, and the determined time T' reaches less than T + T first0Then less than T, and finally less than T-T00。
Also, it should be understood that the notification information is transmitted at time T' and the vehicle and the user arrive at the meeting and the location at the same time.
In summary, then: determined time T' once reaching less than T + T0Sending the notification message at the moment of time requires the user to wait for T0Is useful for delivery vehicles to improve delivery efficiency; once the determined time T' reaches the time less than T, the notification information is sent, so that the delivery vehicle and the user can wait for a short time or even do not need to wait; once the determined time T' is less than T-T00The notification information is sent at the moment, so that the user can receive the service when arriving at the meeting and the position, and the service experience of the user is improved.
In the embodiment of the invention, the time T' is compared with the predicted time T of the meeting and the position of the user to determine the sending of the notification information to the user, namely the sending of the notification information is determined by directly taking the time as a reference, so that the sending time of the notification information is more accurate without interference of other factors except the time, and the time difference of the meeting and the position of the vehicle and the user Q is favorably and accurately controlled.
Example eight:
the notification information sending method provided in this embodiment basically adopts the same steps as those in the sixth embodiment, and therefore, the description is omitted.
The difference lies in that: the message transmission condition is preferably defined. Specifically, the message sending condition includes: the current remaining distance S' and the notification remaining distance S satisfy a predetermined distance relationship, wherein,
the informed remaining distance S is determined from the target speed V and the predicted time T for the user to meet and locate;
the predetermined distance relationship includes the current remaining distance S' being less than one of: remaining distance to send notification S, remaining distance to send notification S plus first redundant distance S0Subtracting the second redundant distance S from the notification residual distance S00。
It should be understood that the predetermined distance relationship includes: s'<S, or the predetermined time relationship comprises: s'<S+S0Or the predetermined time relationship comprises: s'<S+S0That is, the predetermined distance relationships do not simultaneously include: s'<S、S'<S+S0And S'<S+S0。
Specifically, the notification information sending method provided by the present embodiment is shown in fig. 8. Referring to fig. 8, step S103, determining to send notification information to the user according to the current position, the meeting and the position of the vehicle and the predicted time of arrival and the position of the user, includes:
step S103A, according to the predicted time T of the meeting and the position of the user and the speed V of the carrier vehicle, the remaining distance S of the carrier vehicle for sending the notice is determined. Specifically, S ═ V · T may be used.
Step S103B, planning a navigation route according to the current position and the meeting and the position of the vehicle. Specifically, it is also possible to input the current position and meeting and position of the vehicle into a navigation module installed on the vehicle, and then acquire a navigation route planned by the navigation module.
Step S103C, determining the current remaining distance S' for the vehicle to reach the meeting and location along the navigation route.
Step S103D, if the determined current remaining distance S' and the notification remaining distance S satisfy a predetermined distance relationship, it is determined to transmit the notification information to the user.
In particular, the first redundant distance S0Is a parameter that ensures that the vehicle does not need to wait (user needs to wait), and the second redundant distance S00Is a parameter that ensures that the user does not have to wait (the vehicle needs to wait), and thus, the first redundancyDistance S0And a second redundant distance S00All are small values, which can be preset according to actual requirements.
It should be noted that:
(1) in the process of the carrier vehicle reaching the meeting and the position along the navigation route, the current remaining distance S' is collected at a plurality of preset moments.
Based on this, it should be noted that, for any one of the above-mentioned predetermined distance relationships, if the current remaining distance S' is collected at the target time and it is determined that the predetermined distance relationship is satisfied, the notification information is sent and the current remaining distance at each time in the subsequent time period is no longer collected.
(2) During the course of the vehicle reaching the meeting and location along the navigation route, the remaining distance decreases as the vehicle travels, so that the determined current remaining distance S' first reaches less than S + S0Then less than S, and finally less than S-S00。
Also, it should be understood that when the notification information is transmitted when S ═ S, the delivery vehicle and the user arrive at the meeting and the location at the same time.
In summary, then: once the current remaining distance S' reaches less than S + S0The notification information is sent, and the user is required to wait, which is beneficial to the delivery vehicle for improving the delivery efficiency; once the current remaining distance S' is less than S, the notification information is sent, so that the vehicle and the user can wait for a short time or even do not need to wait; once the current remaining distance S' reaches less than S-S00And the notification information is sent, so that the user can be ensured to receive the service when arriving at the meeting and the position, and the service experience of the user is improved.
In the embodiment of the invention, the current remaining distance S 'is compared with the notification remaining distance S to determine to send the notification information to the user, and the current remaining distance S' can be determined by the specific landmark on the meeting and position path, so the notification information can be sent under the condition that the vehicle is determined to travel to a certain position according to the specific landmark, and the determination of the notification information sending time is more convenient.
