In recent years, with the maturity of positioning technology and the rapid development of mobile internet technology, more and more users use electronic map applications to get information about travel paths and surrounding geographic environments. In the actual use of electronic map applications, querying bus-related information through electronic map applications is a type of electronic map functions most frequently used by users.

In the existing electronic map application, when a user wants to query the relevant information of a bus trip, the user manually inputs the bus trip string by virtue of his personal memory of the bus trip. For example, if the user wants to query the relevant information of bus 331, the user enters "331" in the electronic map application. However, if the user makes a mistake in the memory of the bus number, for example, the user mistakenly records the 331 bus as the 337 bus, the result of the user query will be very different from the result he wants.

In response to this situation, a QR code containing information on bus times is set on the kanban board of the bus station. By scanning the QR code, users can accurately obtain the bus trip information. However, it is not a small expense to re-edit and print the QR code for each bus, and such a solution cannot be implemented once the QR code is damaged or blocked.

The current position is the own position of the mobile terminal obtained by the mobile terminal through its own positioning function.

S640. Use the trip number and the current position to obtain the bus trip information.

In this embodiment, while the server receives the bus stop image uploaded by the mobile terminal, it also receives the current location of the user uploaded by the mobile terminal. After receiving the current position of the user uploaded by the mobile terminal, the server combines the current position of the user with the trip number to obtain the bus trip information. In addition, the acquisition of the bus trip information may be obtained by querying a back-end database. The background database query performed in accordance with such a process not only considers the number of buses to be queried, but also considers the current location of the user. For example, the server can According to the user's current location, map elements such as restaurants and schools around the user and the distance between the user and the user are within the distance critical value range, and the user's surroundings and the distance between the user and the user are within the distance critical value range Interchange stations, and possible transfers. Therefore, the given bus trip information can give more targeted information to the user's current location, making the information returned to the mobile terminal more specific and more in line with the actual needs of the user.

S640. Return the bus trip information to the mobile terminal.

In this embodiment, when using the trip number to query the background database, the trip number and the current location of the user uploaded by the mobile terminal are used to query the background database, so that the bus trip information returned to the mobile terminal is more specific and more Fit the actual needs of users.
