Detailed Description

The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

Fig. 1 is a schematic flowchart of an information delivery method according to an embodiment of the present application. The embodiment can be applied to the situation that the target screen point location is determined to release the information of the dragging party. Typically, the embodiment can be applied to the situation that the screen point location is reasonably determined and the delivery information is displayed according to the objective and accurate geographical position of the screen point location, the crowd flow thermodynamic diagram and the attention area determined by the deliverer. The information delivery method disclosed by the embodiment can be executed by an information delivery device, and the device can be realized by software and/or hardware. Referring to fig. 1, the information delivery method provided in this embodiment includes:

and S110, determining the attention area of the thrower according to the interactive operation in the electronic map.

The interactive operation may be an interactive operation between the publisher and a device displaying the electronic map, for example, the device displays the electronic map to the publisher, and the publisher realizes the interactive operation with the device through an operation on a screen of the device. The attention area is used for reflecting the information putting place tendency and the requirement of the putting person. The thrower can perform a circle operation or a click operation on the electronic map to determine the attention area.

Optionally, determining the attention area of the publisher according to the interactive operation includes: the method comprises the steps of obtaining POI selected by a dispenser in an electronic map; a circular area centered on the selected POI is set as the region of interest. As shown in fig. 2 and fig. 3, a publisher may determine a Point of Interest (POI) in an electronic map by means of search box input or click, set a preset length as a radius with the POI as a center, and determine a circular area as a focus area. The preset length can be set according to the actual situation so as to meet the requirement of a release person on an information release area. The circular area determined by the POI selected by the dispenser is used as the attention area, so that the operation of a user is facilitated, the attention area is determined according to the requirement of the user, and the shape of the attention area is normalized, so that the candidate screen point position in the attention area is determined subsequently.

Optionally, after the circular area centered on the selected POI is used as the attention area, the method further includes: and adjusting the size of the attention area in response to the boundary dragging operation of the circular area.

Because the function of dragging the circular boundary cannot be realized in the external API of the existing electronic map, in the embodiment of the application, a brand new view control is created through a self-defined interactive circular view so as to click and drag the circular area, thereby facilitating the operation of a dispenser and improving the accuracy of determining the attention area.

And S120, taking the screen point position belonging to the attention area as a candidate screen point position.

Specifically, the attention area is determined according to the interactive operation of the thrower, so that the attention area can reflect the area requirement and the tendency of the thrower to throw information, and therefore, according to the specific position of each screen point, the screen point belonging to the attention area is determined to be used as a candidate screen point, so that the thrower can conveniently determine the target screen point meeting the condition according to the candidate screen point.

Optionally, taking the screen point belonging to the attention area as a candidate screen point, including: inquiring screen point locations in the attention area based on the geocode indexes, and taking the inquired screen point locations as candidate screen point locations; the geographic codes are integer numbers obtained by splicing longitude codes and latitude codes of screen point positions.

Illustratively, for a screen point location, its longitude code and latitude code are determined, the longitude code is left shifted, and an operation or operation is performed with the latitude code, e.g., the resulting longitude code is 10111001001101000110, the latitude code is 11010010101010100101, the longitude is left shifted: 1011100100110100011000000000000000000000, the execution or operation with dimension coding results in geocoding 1011100100110100011011010010101010100101. Compared with the method of generating geocoding by cross insertion, the coding method of shift and OR operation in the embodiment of the application does not need to accurately search the cross-inserted coding bits, has high operation efficiency, does not need to perform Base32 coding operation, and can reduce the time consumption of coding. In addition, in the process of searching according to the integral digit geocode, the time consumption for calling the hashCode method and the equials method is less, so that the time required by searching is saved, and the searching efficiency is improved.

Optionally, the display modes of different screen point locations can be determined under different scales of the electronic map. For example, as shown in fig. 4, if the scale bar is less than 500 meters, the current display area corresponds to a building, and the screen sites belonging to the building are displayed. As shown in fig. 5, if the scale is 500 m to 2000 m, the current display area corresponds to a business turn, and the screen point location in the business turn is displayed. As shown in fig. 6, if the scale is larger than 2000 m, the current display area corresponds to an urban area, and the screen points in the urban area are displayed.

And S130, displaying the crowd flow thermodynamic diagram of the attention area.

The crowd flow thermodynamic diagram is used for reflecting the crowd flow distribution at a certain position and presenting the crowd flow density at the geographic position. As shown in fig. 7, the areas with different density of the flow of people are represented by different colors to visually represent the flow of people in different areas. In the embodiment of the application, the crowd flow thermodynamic diagrams in the attention areas are displayed, so that the crowd density at different geographic positions is visually displayed, and a dispenser can conveniently determine the geographic position where the dispensing information needs to be displayed according to the thermodynamic diagrams, so that the effective display of the dispensing information is facilitated. It should be noted that thermodynamic diagrams in the attention area and the whole electronic map range may be displayed, so that the presenter may select the screen point location with reference. In addition, the thermodynamic diagram can be displayed in any scene selected by the screen points, for example, in scenes such as clicking the screen points by a thrower, circling the attention area, automatically displaying the screen points according to a scale and the like, so as to provide people flow information.

Optionally, before displaying the crowd thermodynamic diagram of the attention area, the method further includes: responding to the crowd screening operation, and acquiring crowd attribute information selected by a thrower; determining user traffic information which belongs to the attention area and accords with the crowd attribute information; and constructing a thermodynamic diagram of the attention area according to the determined user flow information.

Specifically, since the target audiences corresponding to different delivery information are different, for example, the target audience corresponding to the delivery information of the individual nursing care category is female, and the target audience corresponding to the delivery information of the graduation employment category is graduation students, as shown in fig. 8, the crowd attribute options are displayed for the deliverers, crowd screening operation is performed by the deliverers, user traffic information meeting the crowd attribute information in the attention area is determined according to the crowd attribute information selected by the deliverers, and a thermodynamic diagram is constructed according to the user traffic information, so that the thermodynamic diagram sufficiently reflects the traffic of the target audience in the attention area, and the deliverers can more specifically select the screen points with large traffic of the target audience to display the delivery information.

And S140, acquiring a target screen point location selected from the candidate screen point locations according to the crowd flow thermodynamic diagram for displaying the delivery information.

Specifically, the thrower selects a target screen point location from the candidate screen point locations according to the crowd flow thermodynamic diagram, for example, selects a candidate screen point location located in a crowd dense area in the crowd flow thermodynamic diagram from the candidate screen point locations as the target screen point location, and displays the throwing information at the target screen point location, so as to improve the viewing amount of the throwing information and improve the display effect and the display value of the throwing information. As shown in fig. 9, the candidate screen points include: the Brilliant international mansion, the five-element bridge B seat and the bearing international mansion can be judged according to the displayed crowd flow thermodynamic diagram, and the Brilliant international mansion is positioned in a region with high pedestrian flow, so the Brilliant international mansion can be used as a target screen position.

Optionally, the thermal correlation of the screen point location may be determined according to the following method:

wherein, w_kWeight representing screen point location, k representing screen point location, h_jDenotes the thermal point, d (k, h)_j) And (3) representing a distance function, wherein n represents a weight fixed constant parameter, and the larger the distance range is, the smaller the value of n is. And summarizing the weighted values of the screen point locations to measure the crowd thermal correlation of the screen point locations, and summarizing and determining the target screen point locations from the candidate screen point locations according to the crowd thermal correlation of the screen point locations.

Optionally, before obtaining the target screen point location selected from the candidate screen point locations according to the crowd flow thermodynamic diagram, the method further includes: responding to screen screening operation, and acquiring screen attribute information selected by a dispenser and building attribute information of a building to which a screen belongs; and screening candidate screen point positions in the concerned area according to the screen attribute information and the building attribute information.

For example, as shown in fig. 10, the property information of the screen and the property information of the building to which the screen belongs may be presented to the publisher, so that the publisher can perform the screening according to the actual requirement. The screen attributes may include, among other things, screen size, screen type, screen price, and screen inventory. The building attribute information of the building to which the screen belongs may include: office buildings, residential buildings, shopping malls, schools and the like. The dispenser can select proper screen attribute information and building attribute information according to the displayed screen attribute information and the building attribute information of the building to which the screen belongs, so that different requirements of the dispenser are met.

Optionally, after obtaining the target screen point location selected from the candidate screen point locations according to the crowd flow thermodynamic diagram, the method further includes: and generating release request data according to the information of the target screen point location, and sending a release request to a release system for indicating the release system to release.

As shown in fig. 11, release request data is generated according to the selected target screen point location, an order is formed, and the order is sent to the release system to instruct the release system to release. The release request is generated according to the information of the target point location, and the release system is indicated to release, so that the problems of low efficiency and low accuracy caused by manual generation of the release request are solved, the release information is effectively displayed according to the actual requirements of the release persons, and the reading effect and the value of the release information are improved.
