In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The following detailed description of implementations of the invention refers to the accompanying drawings.
The first embodiment is as follows:
fig. 1 is a schematic structural diagram of a navigation system according to a first embodiment of the present invention, and for convenience of description, only the portions related to the first embodiment of the present invention are shown. The navigation system illustrated in fig. 1 includes a first terminal 11, a second terminal 12 and a server 13, where the first terminal 11 is a terminal providing navigation assistance, the second terminal 12 is a terminal that needs to receive navigation assistance, and the number of the second terminals 12 may be one or at least two. The detailed functions of the first terminal 11, the second terminal 12 and the server 13 are described as follows:
the first terminal 11 imports an instant navigation map and sends the instant navigation map containing position information of a plurality of mark points to the server 13, wherein the position information of the plurality of mark points is information which is set by a user of the first terminal and provides navigation assistance for the second terminal, and the information comprises position information of a starting point, position information of an end point and position information of at least one intermediate point.
Specifically, the first terminal 11, as a terminal providing navigation assistance, may complete a function of providing navigation assistance through a navigation application APP, where the navigation application APP may be provided in a mode of a wechat public number.
After the user of the first terminal 11 starts the Navigation application APP, one or more terminals that need to receive Navigation assistance may be invited, that is, the second terminal 12, and after the invitation is successful, the first terminal 11 may acquire the position information of the user and the position information of the second terminal 12, and optionally, the first terminal 11 may acquire the position information through positioning tools such as a GPS, a BeiDou Navigation Satellite System (BDS), a Wireless Fidelity (WiFi), and a Bluetooth (Bluetooth). The first terminal 11 imports a third-party instant navigation map in the navigation application APP, marks the position of a starting point and the position of an ending point set by a user in the instant navigation map, preferably, the position of the starting point may be the position of one of the second terminals 12, the position of the ending point may be the position of the other second terminal 12, meanwhile, the user of the first terminal 11 selects a suitable intermediate point for the second terminal 12 according to the position of the starting point and the position of the ending point, the first terminal 11 marks the position of the intermediate point set by the user in the instant navigation map, the intermediate point may be an intermediate point where the first terminal 11 and the second terminal 12 meet at a certain position, one or more intermediate points may be provided, and different intermediate points may be set for different second terminals 12, by which a navigation route may be guided to a route that the user intends to plan.
After the user of the first terminal 11 determines the positions of the plurality of marked points including the position of the start point, the position of the end point, and the position of the middle point, the auxiliary navigation function is activated. The first terminal 11 detects that the user starts the auxiliary navigation function, and transmits an instant navigation map containing position information of a plurality of marked points to the server 13.
The server 13 may be a cloud server, and after the server 13 acquires the instant navigation map sent by the first terminal 11, according to the position information of the plurality of marker points included in the instant navigation map, a navigation path from the position of the start point to the position of the end point through the position of the middle point is planned in the instant navigation map, and the instant navigation map including the navigation path is sent to the first terminal 11 and the second terminal 12.
After receiving the instant navigation map containing the navigation path sent by the server 13, the first terminal 11 displays a specific navigation path and positions of the plurality of mark points in the instant navigation map in the navigation application APP, so that a user of the first terminal 11 can check the current navigation path and the positions of the plurality of mark points in real time.
After receiving the instant navigation map containing the navigation path sent by the server 13, the second terminal 12 imports the instant navigation map in the navigation application APP, and displays a specific navigation path and positions of the plurality of marker points in the instant navigation map, so that a user of the second terminal 12 can check the navigation path and the positions of the plurality of marker points in real time, and meanwhile, the user of the second terminal 12 can travel according to the navigation path planned by the first terminal 11 according to the instant navigation map.
Alternatively, the position of the intermediate point may be adjusted at any time, for example, when the user of the second terminal 12 considers that the position of the intermediate point determined by the user of the first terminal 11 is not appropriate, the position of the intermediate point may be adjusted, and the user of the first terminal 11 may also adjust the position of the intermediate point at any time. When the position of the intermediate point is adjusted, the adjusted position information of the intermediate point is transmitted to the server 13, and when the server 13 receives the updated position information of the intermediate point, the current navigation path is updated according to the updated position information of the intermediate point, and the updated navigation path is transmitted to the first terminal 11 and the second terminal 12.
When the first terminal 11 and the second terminal 12 receive the updated navigation path sent by the server 13, the instant navigation map is refreshed according to the updated navigation path, so that the first terminal 11 and the second terminal 12 can both check the current intermediate point position in real time, and real-time interaction and shared path planning among multiple users are realized.
Optionally, during the navigation process of the second terminal 12, the second terminal 12 sends its own real-time location information to the server 13. When the server 13 acquires the real-time position information sent by the second terminal 12, the server 13 sends the real-time position information to the first terminal 11 and the other second terminals 12 in time, so that all users participating in the auxiliary navigation can check the current traveling position of each user in real time, and meanwhile, the server 13 judges whether the current position of the second terminal 12 is on the planned navigation path according to the real-time position information sent by the second terminal 12.
If the current position of the second terminal 12 deviates from the planned navigation path, the server 13 sends a first prompt message to the second terminal 12, where the first prompt message includes the current actual position information and the direction adjustment information of the second terminal 12. When the second terminal 12 receives the first prompt message sent by the server 13, the second terminal 12 sends out a position prompt according to the actual position information in the first prompt message, and sends out a direction adjustment instruction according to the direction adjustment information in the first prompt message. Specifically, the second terminal 12 may issue a prompt of the current actual position of the second terminal 12 in a voice or other prompt manner, and an indication that an adjustment needs to be performed in a specific direction.
Optionally, in the navigation process of the second terminal 12, when the server 13 acquires the real-time location information sent by the second terminal 12, the server 13 calculates a distance between the current location of the second terminal 12 and the middle point, and calculates a time required for the second terminal 12 to reach the middle point, according to the calculated distance and time, the server 13 may send a second prompt message to the first terminal 11 at a preset time interval, where the second prompt message may include the current distance and time information, and the preset time interval may decrease with the decrease of the distance, that is, when the second terminal 12 gradually approaches the middle point, the time interval for sending the second prompt message is shorter. When the first terminal 11 receives the second prompt message sent by the server 13, it sends a status prompt to the second terminal 12 according to the distance and time information contained in the second prompt message. Specifically, the first terminal 11 may issue a status alert to the second terminal 12 in a manner of voice or other alert tones, and the intensity of the alert is increased as the distance between the second terminal 12 and the middle point decreases, so as to alert the user of the first terminal 11 of the distance between the user of the second terminal 12 and the middle point and the time required for reaching the middle point, and alert the user of the first terminal 11 of paying attention to the departure time, so as to join the user of the second terminal 12 at the middle point in time.
Further, after the first terminal 11 and the second terminal 12 converge at the middle point, the server 13 determines that the current position information of the second terminal 12 is consistent with the position information of the middle point, and then sends a third prompt message to the other second terminals 12, and after the other second terminals 12 receive the third prompt message, the other second terminals 12 send out a prompt and a suggestion to the user in time, for example, the user can be prompted to wait for patiently or proceed in opposite directions according to the navigation path.

In the conventional method, a user 1 and a user 2 need to plan a route to a user 3 according to independent navigation tools, and the user 1, the user 2 and the user 3 do not interact and share the route plan in real time, and the position situation of other users cannot be intuitively obtained, but the user 1 is very familiar with the route, can provide navigation assistance, and hopes to join with the user 2 and lead the user 2 to reach the position of the user 3 together, and the user 2 and the user 3 are not familiar with the route and need to receive the navigation assistance, which can be realized by the method provided by the system of the embodiment of the present invention.

User 1 can set up intermediate point P1 with user 2 in this instant navigation map to set up user 2's position as the starting point position, user 3's position is the terminal position, and after the setting was accomplished, user 1 started the auxiliary navigation function in the auxiliary navigation APP. After the start of the assisted navigation function is successful, the user 1, the user 2 and the user 3 can all see the navigation path planned by the system according to the intermediate point P1, the positions of all the users and the position of the intermediate point P1 in the instant navigation map of their assisted navigation APP. At this time, the user 2 can travel according to the navigation path, the user 1 and the user 3 can also check the current position of the user 2 at any time, and whether the user 2 is on the planned navigation path currently, if the user 2 deviates from the navigation path, the system sends a prompt through instant voice to inform the user 2 that the navigation path deviates from and needs to be adjusted towards a specific direction, and simultaneously, the system prompts the user 1 through voice or other prompt tones about the time required by the current user 2 to reach the middle point and reminds the user 1 to pay attention to the departure time, after the user 1 and the user 2 converge, the system can remind the user 3 through instant voice to inform the user 3 that the current user 1 and the user 2 have gone on the way, and please the user 3 go patiently or go towards the directions of the user 1 and the user 2 according to the planned path in the instant navigation map. When the user 1, the user 2 and the user 3 are converged, the navigation is finished.
