[0033] As described in the background art, there are still limitations in the application of the prior art geographical fence technology. The following will be specifically described.

[0034] Currently, the geographical fences on the market are basically areas preset by users in advance. If the user's original intention is to trigger a preset action after entering the geographical fence, but due to traffic congestion, the travel time from the boundary of the geographical fence to the destination exceeds the user's expected time, thus the original intention of the user cannot be achieved, which will bring many inconveniences to the user and further affect the user experience.

[0035] On this basis, the present invention provides a system and method for dynamically adjusting a geographical fence, a storage medium, and a terminal. By adjusting the range of the initial geographical fence boundary in real time, the second real-time travel time is made equal to the regular travel time. Thus, the original time planning intention of the user is achieved, the time planning error caused by environmental factors such as traffic congestion is reduced, and the user experience is effectively improved.

[0036] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe the specific embodiments of the present invention in detail with reference to the accompanying drawings.

[0037] Figure 1 It is a flowchart of a method for dynamically adjusting a geographical fence according to an embodiment of the present invention.

[0038] Please refer to Figure 1 , the method for dynamically adjusting a geographical fence described in this embodiment includes the following steps:

[0039] Step S101, establish an initial geographical fence boundary centered on the destination;

[0040] Step S102, obtain the best travel path between the destination and the current location, and the best travel path has a first boundary intersection with the initial geographical fence boundary;

[0041] Step S103, on the best travel path, obtain the regular travel time between the first boundary intersection and the destination;

[0042] Step S104, on the best travel path, obtain the first actual travel time between the first boundary intersection and the destination;

[0043] Step S105, if the regular travel time is not equal to the first actual travel time, adjust the range of the initial fence boundary to form a geographical fence boundary. The best travel path has a second boundary intersection with the geographical fence boundary. On the best travel path, there is a second real-time travel time between the second boundary intersection and the destination, and the second real-time travel time is equal to the regular travel time.

[0044] The following will describe each step of the method for dynamically adjusting a geographical fence in detail with reference to the accompanying drawings.

[0045] Figures 2 to 6 It is a structural schematic diagram of each step of the method for dynamically adjusting a geographical fence according to an embodiment of the present invention.

[0046] Please refer to Figure 2 , take the destination O1 as the center and establish an initial geographical fence boundary S1.

[0047] In this embodiment, the method for establishing the initial geographical fence boundary S1 includes: establishing the initial geographical fence boundary S1 with reference to the expected travel time according to empirical rules.

[0048] In this embodiment, after establishing the initial geographical fence boundary S1, it further includes: providing the expected travel time t p .

[0049] Please refer to Figure 3 , and obtain the best travel path P between the destination O1 and the current location O2. The best travel path P and the initial geographical fence boundary S1 have a first boundary intersection point F1.

[0050] In this embodiment, the method for obtaining the best travel path P between the destination O1 and the current location O2 includes: obtaining real-time traffic information; obtaining the best travel path P between the destination O1 and the current location O2 according to the obtained real-time traffic information.

[0051] In this embodiment, the real-time traffic information is mainly provided by professional traffic condition providers. Map service providers cooperate with them to obtain real-time traffic information. The main acquisition channels of traffic condition providers mainly include: data provided by traffic management departments; judgment based on vehicle speed (the data sources of vehicle speed mainly include fixed vehicles equipped with driving recorders, such as buses and taxis, and also include data automatically uploaded by mobile phone users using map software for navigation); users reporting traffic conditions by themselves in the mobile map APP.

[0052] The best travel path P is calculated and obtained based on the real-time traffic information, and is usually the shortest travel path or the shortest time-consuming path determined according to the user's selection.

[0053] In this embodiment, the best travel path P also includes the best path passing through a preset waypoint O3. For example, when a user travels from the current location O2 to the destination O1 and needs to pass through a preset waypoint O3 (such as a shopping mall, a restaurant, etc.), the preset waypoint O3 can be additionally input between the current location O2 and the destination O1, so that the best travel path can cover the current location O2, the preset waypoint O3 and the destination O1 at the same time, avoiding multiple operations by the user.

[0054] Please refer to Figure 4 , and obtain the normal travel time t between the first boundary intersection point F1 and the destination O1 on the best travel path P r .

[0055] In this embodiment, the normal travel time t r is the travel time in most cases obtained based on past real-time traffic information.

[0056] In this embodiment, if the expected travel time t P and the conventional travel time t r have a difference greater than a preset threshold, a reminder is given to re-establish the initial geographical fence boundary. Since the conventional travel time t r of the initial geographical fence boundary S1 established by the user according to the empirical rule may have a large uncertainty, therefore, by comparing the conventional travel time t r with the expected travel time t P if the difference is within a large range, the user is reminded to re-establish the initial geographical fence boundary S1 to ensure that the initial geographical fence boundary S1 established by the user is within a reasonable range.

[0057] Please refer to Figure 5 , on the optimal travel path P, obtain the first actual travel time t1 between the first boundary intersection point F1 and the destination O1.

[0058] In this embodiment, since the real-time traffic condition information includes the travel speed on the optimal travel path P and the travel distance between the first boundary intersection point F1 and the destination O1 on the optimal travel path P. Therefore, the first actual travel time t1 between the first boundary intersection point F1 and the destination O1 is obtained according to the travel distance between the first boundary intersection point F1 and the destination O1 in the real-time traffic condition information / the travel speed on the optimal travel path P.

[0059] Please refer to Figure 6 , if the conventional travel time t r is not equal to the first actual travel time t1, adjust the range of the initial fence boundary S1 to form a geographical fence boundary S2. The optimal travel path P and the geographical fence boundary S2 have a second boundary intersection point F2. On the optimal travel path P, there is a second real-time travel time t2 between the second boundary intersection point F2 and the destination O1, and the second real-time travel time t2 is equal to the conventional travel time t r .

[0060] In this embodiment, by adjusting the range of the initial geographical fence boundary S1 in real time, the second real-time travel time t2 is made equal to the conventional travel time t r . Thus, the original time planning intention of the user is achieved, the time planning error caused by environmental factors such as traffic congestion is reduced, and the user experience is effectively improved.

[0061] In this embodiment, if the conventional travel time t rWhen it is not equal to the first actual travel time t1, the method of adjusting the range of the initial fence boundary S1 to form a geographical fence boundary S2 includes: obtaining the regular travel time t r The time ratio β between the first actual travel time t1; according to the time ratio β, adjusting the range of the initial fence boundary S1 to form a geographical fence boundary S2.

[0062] In this embodiment, the method of adjusting the range of the initial fence boundary S1 to form a geographical fence boundary S2 according to the time ratio β includes: when the initial geographical fence boundary S1 is circular, scaling the radius of the circle by a ratio of β times to form the geographical fence S2.

[0063] In other embodiments, the method of adjusting the range of the initial fence boundary S1 to form a geographical fence boundary S2 according to the time ratio β further includes: when the initial geographical fence boundary S1 is rectangular, scaling the side lengths of the rectangle by a ratio of β times to form the geographical fence S2.

[0064] For example, in some scenarios, the user presets an instruction to trigger the opening of the air conditioner at home when getting off work. The air conditioner needs 10 minutes for precooling. The user estimates that it takes 10 minutes (i.e., the regular travel time t r ) for a car journey of about 3 kilometers. So the user sets up an initial geographical fence boundary S1 centered on home (i.e., the destination O1) with a radius of 3 kilometers. When the user enters the initial geographical fence boundary S1, the smart home system turns on the air conditioner. If there is a traffic jam, the user finds that it takes 30 (i.e., the first actual travel time t1) minutes to get home after entering the initial geographical fence boundary S1, which is equivalent to wasting 20 minutes of electricity.

[0065] Therefore, by the method of dynamically adjusting the geographical fence, scaling the radius of the initial geographical fence boundary S1 (such as a circle) by a ratio of β (i.e., t r / t1 = 1 / 3) times to form the geographical fence boundary S2. The radius of the dynamically adjusted geographical fence boundary S2 is 1 / 3 of the radius of the initial geographical fence boundary S1. The corresponding second boundary intersection point F2 and the destination O1 have a second real-time travel time t2 that is 1 / 3 of the first actual travel time t1 (i.e., 30 * 1 / 3 = 10 minutes). Therefore, the second travel time t2 is equal to the regular travel time t r When the user triggers the geographical fence boundary at this time, the time to get home is equal to the time planned at the beginning, thus achieving the user's original time planning intention, reducing the time planning error caused by environmental factors such as traffic congestion, and effectively improving the user experience.
