Description

A method for publishing information on charging piles

technical field

The invention relates to an information release method for a charging pile.

Background technique

With the continuous development of the electric vehicle industry, electric vehicle charging piles are also being continuously laid on both sides of main roads, parking lots, shopping malls and other places in various urban areas. Therefore, electric vehicle charging piles can be used to release information, so as to provide more and better services for the majority of charging users.

However, in the process of distributing information, if charging users are not interested, electric energy will be wasted in vain, and the service quality cannot be further improved.

Contents of the invention

The purpose of the present invention is to provide an information release method for charging piles to solve the problem that the existing information release cannot meet the needs of users and waste electric energy.

To achieve the above object, the solution of the present invention includes:

An information release method for a charging pile, the steps are as follows: 1) When a user is charging, the charging pile detects the user and the corresponding vehicle, and sends the corresponding user ID and vehicle ID to the server; and vehicle ID, select the corresponding information ID in the user's interested information list, and return the information ID to the charging pile; in the interested list, the information ID corresponds to a priority value; the server side chooses first The corresponding information ID with high level value is returned to the charging pile; 3) The charging pile selects the information corresponding to the information ID and stored locally, and releases it through the display screen of the charging pile; Feedback to determine the degree of interest of the user, and send the degree of interest to the server, and the server updates the user's interest information list according to the degree of interest.

Further, in the step 4), the degree of interest includes: interested and not interested; for information that is not of interest, the server end reduces the priority value of the corresponding information ID; for interested information, the server end increases the corresponding information ID the priority value of .

Further, in the step 4), the user evaluates the released information by selecting the button on the charging pile or the display screen, and the evaluation result is interested or not interested.

Further, in the step 4), the charging pile detects the user's line of sight through the camera device installed on it, and determines the time of the user's attention to the information according to the user's line of sight. If the time of the user's attention to the information exceeds the set threshold, it is judged to be interested, and vice versa. not interested.

Further, in step 2), the priority value is also related to the situation of the user and the vehicle, the geographical location of the charging pile, the current season, weather, and time.

Through the user's feedback, the priority value of each information can be dynamically adjusted, and the information can be released according to the actual needs of the users, so that the needs of the users can be switched and the power can be saved.

Determine the time when the user pays attention to the information through the user's line of sight, realizes complete automatic processing, does not require any operation by the user, and has good interactivity.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings.

Example 1

Figure 1 shows the structure diagram of the information publishing system of the charging pile. The function of the communication network is mainly to complete the information interaction between the application server and the charging pile. In this article, the application server and database are server-side, and the charging pile is local.

An information release method for a charging pile according to the present invention, comprising:

1) When the user is charging, the charging pile detects the user and the corresponding vehicle, and sends the corresponding user ID and vehicle ID to the server;

2) According to the user ID and vehicle ID, the server selects the corresponding information ID in the user's information list of interest, and returns the information ID to the charging pile; in the interest list, the information ID corresponds to Priority value; the server side preferentially selects the corresponding information ID with high priority value and returns it to the charging pile;

3) The charging pile selects the locally stored information corresponding to the information ID, and releases it through the display screen of the charging pile;

4) During the release process, the user's feedback on the published information is detected to determine the user's interest level, and the interest level is sent to the server, and the server updates the user's interest information list according to the interest level.

The various technical means involved in the above method will be described in detail below.

In step 1), the user ID is read by the charging pile when swiping the card. The user information corresponding to the user ID includes user gender, age, occupation, vehicle model, vehicle purchase time, and the like. Vehicle ID, when charging starts after the charging cable is connected to the vehicle. The vehicle can communicate with the charging pile, the vehicle identification ID collected by the charging pile, and the vehicle information corresponding to the vehicle ID includes information such as vehicle model and fuel consumption. Both user information and vehicle information are stored on the server side.

In step 2), the server side stores a list of interested information, and a specific implementation method is: each type of information corresponds to an information ID. For each user, there is correspondingly a list of interested information, recording the information ID and the corresponding priority value, as shown in the following table:

In this embodiment, factors that affect the priority value include: 1. Vehicle information of user information. For example, users pay attention to different information due to different ages and occupations, and different information to focus on due to different vehicle models. 2. The geographical location information of the charging pile itself. If the charging pile is located in a busy city or a remote village, the user's attention will be different. 3. The current season, weather, and time information, according to the morning, noon, and evening, different time periods and seasons, the user's attention will also change.

For the above factor 2, the charging pile needs to upload its own ID, and on the server side, each charging pile ID corresponds to its geographical location information. For the above factor 3, the charging pile shall upload the current time, or the server shall record the time when the charging pile uploads other information IDs.

For any piece of information, factor 1, factor 2, and factor 3 respectively correspond to priority values, and the priority values corresponding to factor 1, factor 2, and factor 3 are also set. For example, for shopping information, the priority value when the location of the charging pile is in a busy city is higher than the priority value when the charging pile is located in a remote village. When the information corresponding to factor 1 changes, the corresponding priority value also changes accordingly.

When selecting an information ID, for any information, in addition to the relatively fixed priority values of factors 1, 2, and 3, factor 4: the degree of interest of the user must also be considered.

The degree of interest of the user, including interest and disinterest; for information that is not of interest, the server-side decreases the priority value of the corresponding information ID; for information of interest, the server-side increases the priority value of the corresponding information ID. That is, factors 1, 2, 3, and 4 jointly determine the priority value of a certain information. Calculation methods include: direct summation or weighting.

In this embodiment, in step 4), the user evaluates the released information by selecting the button on the charging pile or the display screen, and the evaluation result is interested or not interested.

Through the user's feedback, the priority value of each information can be dynamically adjusted, and the information can be released according to the actual needs of the users, so that the needs of the users can be switched and the power can be saved.

If the user is interested in a certain information, if the user's mobile phone is registered on the server side, a push or message can be sent to the mobile phone so that the user can further understand the information.

If the total amount of information is large, it is not necessary to calculate the priority values of all information to determine which information IDs to send to the charging pile every time it is released. The scope of the total information can be narrowed down, for example, only the information corresponding to the user and vehicle information with a higher priority value can be selected.

In addition, when updating the list of interested information, it is also applicable to operations such as deletion and addition, such as deleting information whose priority value is too low.

Example 2

The only difference from Embodiment 1 is that in step 4), the charging pile detects the user's line of sight through the camera device installed on it, and determines the time of the user's attention to the information according to the user's line of sight. If the time of the user's attention to the information exceeds the set threshold, it is judged as interested , otherwise it is not interested.

As shown in Figure 2, the workflow of the charging pile includes: when the information starts to play, the charging pile camera device (such as a camera) starts video tracking the user, and uses the method of estimating the line of sight based on the video combined with pupil and corneal reflection, and the line of sight tracking module It will calculate the user's continuous attention time t on the information: when t≥5s, the system judges that the user is interested in this information. When 1s<t<4s, the system judges that the user has seen this piece of information and is not interested in it. When 0s≤t≤1s, the system judges that the user may not have viewed the information due to other reasons. Then the charging pile sends the user's feedback of interest, disinterest, and not seen to the server, and the server modifies the priority value accordingly: increase if interested, decrease if not interested, and remain unchanged if not seen.

After time accumulation, the list of interested information is more and more in line with the information bias of the user's own needs.

Regarding the gaze tracking module, products and methods in the prior art can be used for gaze estimation based on video combined with pupil and corneal reflection, and therefore, no specific introduction to these contents will be made here.
