Second embodiment:
In the prior art, a user can inquire about charging stations on a driving path through a Goldmap and randomly select one charging station for charging. Assume that 3 charging stations exist on the driving path, namely charging station a, charging station B and charging station C, and distances of the 3 charging stations are respectively from near to far: charging station a, charging station B, and charging station C. Assuming that the user selects charging station a, since only the travel path to charging station a can be displayed in the prior art, since charging station a is generally larger, there are more vehicles, and if only charging pile a is navigated to, it is still time-consuming for the user to find an idle charging pile if the user is unfamiliar with charging station a, and in the searching process, the idle charging pile is likely to be found first by other vehicles. In addition, since the traveling process is time-consuming, it is assumed that the free charging post in the charging station a is used up during the traveling process, once the user travels into the charging station a, the user needs to wait if he wants to charge in the charging station a, and time is wasted, and if he does not need to search for a new charging station again, there is no doubt that great inconvenience is brought to the user (for example, the cruising of the user's vehicle cannot support the user to reach the next charging station, and long waiting must be performed in the charging station a).
In order to solve the above technical problems, as shown in fig. 2, the present application provides a charging station map generation method based on image recognition, which specifically includes the following steps:
step S201 receives an inquiry signal for inquiring about a charging station around the current travel route of the vehicle.
It should be understood that, before the specific use, the charging station map generating method based on image recognition in the embodiment of the present disclosure may first install application software with a navigation function on an electric vehicle. Or directly through application software with navigation function installed on the user terminal.
For example, when a user wants to inquire about a nearby charging station, he or she can directly click on a "charging station inquiry" touch screen button on the electric vehicle, at which time an inquiry trigger signal is generated. And the vehicle enterprise client sends the charging station inquiry trigger signal to the vehicle enterprise server, and the vehicle enterprise server starts to inquire about charging stations nearby the electric vehicle after receiving the charging station inquiry trigger signal. For another example, when the user wants to inquire about a nearby charging station, the user may directly input or click on the application software having the navigation function, thereby completing inquiry about the nearby charging station.
It is to be understood that the above is by way of example only and not by way of limitation.
Step S202, displaying a plurality of charging stations within a preset range from the current vehicle and usage information of charging piles in each charging station.
As one embodiment, screening charging stations within a preset range is performed by acquiring the current vehicle location. For example, latitude and longitude coordinates obtained by LBS technology. LBS (Location Based Service, location-based service), among other things, is a technology that utilizes the geographic location of a user or device to provide personalized information, advice, or functionality. LBS relies on GPS (global positioning system), cellular network infrastructure, wi-Fi or a combination of these technologies to determine the geographic location (including longitude and latitude) of a user or device.
It is to be understood that the above is by way of example only and not by way of limitation.
The specific setting of the preset range can be set according to actual requirements, for example, within 2 km or 5 km. Here, the present invention is not particularly limited.
The usage information refers to how many charging piles are in the charging station and how many free charging piles are in the charging station.
Step S203, determining a target charging station from the plurality of charging stations.
As an embodiment, step S203 includes: acquiring a determination signal input by a user based on the displayed use information of the charging stations and the charging piles in the charging stations; and determining a target charging station according to the determination signal.
For example, the user clicks (e.g., clicks) through information displayed by the user terminal/vehicle terminal (center screen) to determine a target charging station. Assume that 3 charging stations are shown, charging station a, charging station B and charging station C, respectively, wherein charging station a has 10 free charging posts and is 10 km from the current vehicle, charging station B has 8 free charging posts and is 6 km from the current vehicle and charging station C has 5 free charging posts and is 12 km from the current vehicle. The user will typically prefer to select a charging station that is closer in distance, assuming the user selects charging stake B.
Step S204 determines an estimated time of arrival of the current vehicle at the target charging station.
As one embodiment, step S204 includes: acquiring the average running speed of the current vehicle, the distance from the target charging station and the running road condition of the current vehicle running to the target charging station; and according to the average running speed, the distance and the estimated arrival time of the running road condition to the target charging station.
The driving road conditions comprise the number of traffic lights which need to wait, the traffic jam condition in front and the like. That is, the driving road condition is a condition requiring additional time consumption in the process of driving to the target charging station.
For example, assuming a clear path to the target charging station, the expected arrival time is the distance divided by the average travel speed. If 2 traffic lights need to wait for each traffic light in the process of traveling to the target charging station, and each traffic light waits for about 20 seconds, then the estimated arrival time=distance/average travel speed+40 seconds.
The average speed indicated above is predicted according to the clear running and the road speed limit, and the specific calculation is referred to the prior art, and is not specifically limited herein.
In a possible embodiment, after step S204, the method further comprises: and deleting the target charging station and redisplaying other charging stations except the target charging station if the estimated reaching time is greater than a threshold value.
It can be understood that, because the estimated arrival time exceeds the threshold value, reservation cannot be performed, by deleting the displayed charging station from the display interface, only other charging stations are redisplayed, so that the user can reselect conveniently, the user is prevented from continuously selecting the charging station which cannot be reserved, and the possibility of charging to the user is improved.
In another possible embodiment, after step S204, the method further includes: if the estimated time is greater than a threshold, displaying first prompt information, wherein the first prompt information is used for prompting that the current vehicle does not meet the requirement of the reserved charging pile; and after the preset time interval, displaying second prompt information, wherein the second prompt information is used for prompting that the current vehicle meets the requirement of reserving the charging pile of the target charging station.
The preset time may be designed according to specific situations, for example, 2 minutes or 5 minutes.
It can be appreciated that in this embodiment, when the expected arrival time exceeds the threshold, the user can intuitively understand why the reservation cannot be made by the prompt mode, and in addition, the intelligent prompt is realized by matching the charging pile again for the user after the preset time interval, so that the operation times of the user are reduced, and the driving safety is improved.
And step S205, if the estimated time is smaller than a threshold value, receiving a charging pile reservation request initiated by the current vehicle.
Optionally, the threshold is less than 30 minutes.
That is, the user can make a reservation of the charging pile only in the case where the estimated arrival time is less than 30 minutes, and cannot make a reservation in the case where the estimated arrival time is greater than or equal to 30 minutes.
As an application scenario, a user may initiate a charging pile reservation request through a virtual reservation button displayed on a user terminal/central control screen. For example by clicking the virtual subscription button.
Of course, the reservation can also be performed by voice input, that is, voice instructions input by the user are collected, and the reservation is performed by analyzing the voice instructions and according to the voice instructions. For example, first, a voice instruction of a user is converted into text using a voice recognition API (e.g., hundred degree voice recognition API, ali voice recognition API, etc.). Then, the intention of the user is understood through natural language processing technology, and corresponding operations such as inquiring the position and the use state of the charging pile, reserving the charging pile and the like are performed. Finally, the result of the operation is fed back to the user in the form of voice through the voice synthesis technology, such as successful reservation.
Optionally, receiving the charging pile reservation request initiated by the current vehicle includes: acquiring the reserved payment amount matched with the expected arrival time; displaying the reserved payment amount; and receiving a charging pile reservation request initiated by the user according to the reservation payment amount.
The method comprises the steps of establishing an association relation table of expected arrival time and reserved payment amount in advance, and then rapidly determining reserved payment amount to be paid by a user in a table look-up mode. For example, the expected arrival time t <10, the reserved payment amount is m1, if 10< t <15, the reserved payment amount is m2, if 15< t <25, the reserved payment amount is m3, if 25< t <30, the reserved payment amount is m4.
For example, assume that the user drives to a selected target charging station for an estimated time of arrival of 7 minutes, which only needs to pay 10 yuan. And if the expected arrival time is 13 minutes, 20 yuan is required.
It can be understood that the reservation payment amount is determined according to the length of the expected arrival time, so that user experience can be improved on one hand, reservation management of the reservation charging pile can be realized on the other hand, and the probability of malicious reservation is reduced.
Optionally, receiving the charging pile reservation request initiated by the current vehicle includes: acquiring reserved charging unit price corresponding to the estimated arrival time; determining a reserved payment amount according to the estimated arrival time and the reserved charging unit price; displaying the reserved payment amount; and receiving a charging pile reservation request initiated by the user according to the reservation payment amount.
Wherein the reserved charging unit price is floating, which is dynamically changed with the change of charging time. And the reserved charge unit price may be stored in advance according to the charge period. At the time of acquisition, it may be looked up by means of a look-up table or a query database.
It is understood that the reserved payment amount=estimated arrival time×reserved charging unit price.
For example, assuming that the expected arrival time is 25 minutes and the current reserved charge unit price is 0.5 yuan, the user needs to reserve a payment amount of 25×0.5=7.5 yuan. I.e. the user needs to pay a fee of 7.5 yuan in advance.
The reserved charging unit price may be equal to or different from the actual charging unit price, that is, the reserved charging unit price and the reserved charging unit price may be the same or different. Such as the reserved charging unit price, can be used only when reserved charging piles are used.
It can be understood that the reservation payment amount can be determined through the expected arrival time and the reservation charging unit price, so that the accurate reservation payment amount can be calculated more quickly, and therefore, more reasonable reservation payment amounts can be given for different arrival times, and the requirement of a user on reservation is improved.
And step S206, determining an idle charging pile as a reserved charging pile according to the charging pile reservation request and collecting a position image of the reserved charging pile in the target charging station.
The reserved charging pile is marked as a use state, and other users cannot use the reserved charging pile in the use state.
It should be noted that, in the present application, the reserved charging pile is not only reserved in literal sense, but is directly locked, so that the reserved charging pile is not used by other users, and thus, after the user who successfully reserves is navigated to the charging pile, the reserved charging pile can be used, and is not used by other users first because of driving time and searching time.
As an application scenario, when a reservation request is sent to a target charging station, an image acquisition device in the target charging station can acquire an image of a reserved charging pile in the charging station under the current environment.
Optionally, determining, according to the charging pile reservation request, that an idle charging pile is a reserved charging pile includes: analyzing the reservation request of the charging pile to obtain the identification of the reserved charging pile and reservation payment information; and when the reserved payment information accords with a preset rule, marking the idle charging pile corresponding to the identification of the reserved charging pile as the reserved charging pile.
The reserved payment information comprises payment conditions of the user, such as the amount of paid fees and the like.
The preset rules are used for judging whether the user pays fees and whether the paid reserved fees meet the minimum requirements.
And step S207, generating and displaying a navigation map for navigating to the reserved charging pile according to the position image.
In a possible embodiment, the method further comprises: driving to the reserved charging pile according to the navigation map; receiving a use password of the reserved charging pile input by a user; after verifying that the use password is legal, marking the state of the reserved charging pile as an available state; and when the reserved charging pile is in an available state, the reserved charging pile is used for charging the vehicle.
In a possible embodiment, the method further comprises: receiving a cancellation signal initiated by a user for canceling the reserved charging pile; determining whether the user satisfies a cancellation rule; if not, deducting the default fee from the reserved fee according to the cancellation rule, and returning the residual fee to the user; and if the cancellation rule is met, returning the reserved payment to the user.
It can be understood that by setting the cancellation mechanism, the user can conveniently decide whether to cancel according to the actual situation of the user, and the use experience of the user is improved. In addition, whether the user needs to pay the fee or not is determined when canceling, so that loss of the charging station is reduced, and malicious reservation probability is reduced.
In summary, according to the charging station map generation method based on image recognition provided by the embodiment, the charging pile can be reserved according to the running time and the running route of the user, so that the charging pile is prevented from being occupied by other users before the user arrives at the charging station, the user time is wasted, and great inconvenience is brought to the user.
