The optimal mobile network corresponding to each passing path is the optimal mobile network in the signal strength of the mobile networks of multiple systems supported by the navigation device.
For example, in the embodiment shown in fig. 2, the navigation device supports a mobile network of a first system and a mobile network of a second system. The signal strength of the mobile network of the first standard on the traffic path 21 is a211The signal strength of the mobile network of the second standard on the traffic path 21 is A212(ii) a The signal strength of the mobile network of the first system on the traffic path 22 is a221The signal strength of the mobile network of the second standard on the traffic path 22 is a222. When A is211＞A212When the optimal mobile network corresponding to the passing path 21 is the mobile network of the first standard, when A is211＜A212Then, the optimal mobile network corresponding to the passing path 21 is the mobile network of the second standard; when A is221＞A222When the optimal mobile network corresponding to the passing path 22 is the mobile network of the first standard, when A is221＜A222Then, the optimal mobile network corresponding to the passing path 22 is the mobile network of the second standard.

Further, as shown in fig. 3, the determining a navigation path in the passing path in step S12 according to the path parameter of each passing path and the signal strength of the optimal mobile network corresponding to each passing path may specifically include the following steps:
and S121, dividing each passing route into a plurality of route units.
Specifically, when any traffic route is divided into a plurality of route units in step S121, the traffic route may be divided based on the signal strength of the mobile network signal, or may be divided based on the distance. When dividing based on the signal intensity of the mobile network, if the signal intensity of the optimal mobile network in the signal intensities of the mobile networks of a plurality of systems supported by the navigation device in a road section of a passing route is the same or approximately the same, the road section can be divided into a route unit; when the division is based on the distance, the sections of the same distance length within a traffic route can be divided into one route unit.
For example, referring to fig. 4, in fig. 4, two paths (41, 42) are shared from the starting position S to the ending position E, and the traffic path 41 is divided into a path unit 411 and a path unit 412, and the traffic path 42 is divided into a path unit 421 and a path unit 422. The navigation device supports a mobile network of a first standard and a mobile network of a second standard, and the signal strength of the mobile network of the first standard on the path unit 411 is A4111The signal strength of the mobile network of the second standard on the path unit 411 is a4112The signal strength of the mobile network of the first standard on the path unit 412 is a4121The signal strength of the mobile network of the second standard on the path unit 412 is a4122The signal strength of the mobile network of the first standard on the path unit 421 is a4211The signal strength of the mobile network of the second standard on the path unit 421 is a4212The signal strength of the mobile network of the first standard on the path unit 422 is a4221The signal strength of the mobile network of the second standard on the path unit 422 is a4222。
And S122, acquiring the signal intensity of the optimal mobile network corresponding to each path unit.
The optimal mobile network corresponding to each path unit is the optimal mobile network in the signal strength of the mobile networks of multiple systems supported by the navigation device.
Specifically, in the embodiment shown in FIG. 4, when A is4111＞A4112When the signal strength of the optimal mobile network corresponding to the path unit 411 is a4111(ii) a When A is4111＜A4112The signal strength of the optimal mobile network corresponding to the path unit 411 is a4112(ii) a When A is4121＞A4122When the signal strength of the optimal mobile network corresponding to the path unit 412 is a4121(ii) a When A is4121＜A4122When the signal strength of the optimal mobile network corresponding to the path unit 412 is a4122(ii) a When A is4211＞A4212When the signal strength of the optimal mobile network corresponding to the path unit 421 is a4211(ii) a When A is4211＜A4212The signal strength of the optimal mobile network corresponding to the path unit 421 is a4212(ii) a When A is4221＞A4222When the signal strength of the optimal mobile network corresponding to the path unit 422 is a4221(ii) a When A is4221＜A4222When the signal strength of the optimal mobile network corresponding to the path unit 422 is a4222。
And S123, acquiring the signal intensity of the optimal mobile network corresponding to each passing path according to the signal intensity of the optimal mobile network corresponding to each path unit.
Specifically, when the passing path is divided into path units based on the signal strength of the mobile network, the signal strength of the optimal mobile network corresponding to each passing path is obtained according to the signal strength of the mobile network on each path unit, which may specifically be:
I. and acquiring the weight of each path unit according to the length of the path unit and the total path length.
For example: the total length of the traffic path 41 is 100m, the length of the path element 411 is 60m, the length of the path element 412 is 40m, the weight of the path element 411 is 0.6, and the weight of the path 412 is 0.4.
II. And acquiring the signal intensity of the optimal mobile network corresponding to each passing path according to the signal intensity of the optimal mobile network corresponding to each path unit and the weight of the path unit.
As described above, the weight of the path unit 411 is 0.6, the weight of the path 412 is 0.4, and the signal strength of the optimal mobile network corresponding to the path unit 411 is a4111The signal strength of the optimal mobile network corresponding to the path unit 412 is a4122Then, the signal strength of the optimal mobile network corresponding to the passing path 41 is: a. the41＝0.6*A4111+0.4*A4122。
When the passing path is divided into path units based on the path length, the signal strength of the optimal mobile network corresponding to each passing path is obtained according to the signal strength of the optimal mobile network corresponding to each path unit, which may specifically be:
and taking the average value of the signal intensity of the mobile network on each path unit as the signal intensity of the optimal mobile network corresponding to each passing path.
For example: the total length of the path 42 is 100, the length of the path unit 421 is 50, the length of the path unit 422 is 50, and the signal strength of the mobile network on the path unit 421 is a4211The signal strength of the mobile network on path element 422 is A4222Signal strength a of the mobile network on path 4242＝(A4211+A4222)/2。
And S124, determining a navigation path in the passing paths according to the path parameters of the passing paths and the signal intensity of the optimal mobile network corresponding to the passing paths.
Further, an embodiment of the present application provides an implementation manner for determining a navigation path in a passing path according to the path parameter of each passing path and the signal strength of the optimal mobile network corresponding to each passing path in step S12. Specifically, referring to fig. 5, the method includes the following steps:
s51 according to the formula fi＝Ai*x+(1-x)*BiAnd calculating a recommendation factor of each passing path.
Wherein f isiRecommendation factor for passage path i, AiThe signal intensity of the optimal mobile network corresponding to the passing path i is obtained; b isiX is a constant greater than 0 and less than 1, which is a road condition parameter of the passing path i.
The road condition parameters of the passing path can be calculated and obtained according to one or more of information such as the length of the passing path, the congestion degree, the road condition of the path, the weather condition on the path and the like. And when the length of the path is shorter, the congestion degree of the path is lower, the road condition of the path is better, and the weather condition on the path is better, the corresponding road condition parameters are larger.
For example, referring to fig. 6, the following illustrates a process of calculating the recommendation factor of each passing path in the above embodiment by taking the road condition parameter of the passing path obtained by calculation according to the length of the passing path, and taking x as 0.1 as an example. As shown in fig. 6, two traffic routes (61, 62) are shared from the start position S to the end position E. Wherein, the length of the passing route 61 is: 10 kilometers (km), the length of transit path 62 is: 15 kilometers (km), the road condition parameter B of the passing path 6161May be the difference between the total length of all traffic paths and the length of traffic path 61, i.e. B61(10+15) -10-15; similarly, the traffic condition parameter B of the traffic path 6262May be the difference between the total length of all traffic paths and the length of traffic path 62, i.e. B6210-15. Furthermore, the signal strength a of the optimal mobile network corresponding to the transit path 6161Signal strength a of the optimal mobile network for transit path 62 of-100 dBm62Is-110 dBm. The calculation formula substituted into the recommendation factor is as follows:
the recommended factors for the transit path 61 are:
f61＝A61*x+(1-x)*B61＝100*0.1+(1-0.1)*15＝23.5；
the recommended factors for the transit path 62 are:
f62＝A62*x+(1-x)*B62＝110*0.1+(1-0.1)*10＝20。
it should be noted that, in the above embodiment, two passing paths are taken as an example for description, but the embodiment of the present application is not limited thereto, and more passing paths may be included from the starting position to the ending position in the actual navigation process, for example, 3, 4, 10, and the like, but the calculation process of the recommendation factor of each path is the same as the calculation process of the recommendation factor of the passing path 31 or the passing path 32, and therefore, detailed description is not repeated for avoiding redundancy.
It should be further noted that, in the calculation formula of the recommendation factor, x is a weighting factor of the signal strength of the optimal mobile network corresponding to the passing path, and 1-x is a weighting factor of the road condition parameter. The value of x can be set according to the influence of the signal strength of the mobile network on the navigation. For example: when the navigation method is used for automatically driving a vehicle or a blind guiding robot, if the signal intensity of the mobile network is too weak, situations such as vehicle runaway and blind getting lost can be caused, and therefore, when the navigation method is used for automatically driving a vehicle or a blind guiding robot, the value x can be set to be larger. For another example: when the navigation method is used for general navigation, when the signal strength of the mobile network is weak, no serious effect is caused, so that the value of x can be set to be smaller at the moment.
And S52, selecting the traffic path with the maximum recommendation factor as the navigation path.
Illustratively, in the embodiment shown in fig. 6 described above, the recommendation factor f for the transit path 616123.5, recommendation factor f for transit path 6262＝20，f61＝23.5＞f6220; the route 61 is selected as a navigation route from the start position S to the end position E. In addition, in some embodiments, a case may also occur where the recommendation factors of the two traffic paths are equal and maximum, and at this time, any one of the two traffic paths with the maximum recommendation factor may be selected as the navigation path.
It should be further noted that, in the above embodiment, the traffic route with the largest recommendation factor is selected as the navigation route, and when the recommendation factor of a certain traffic route is not the largest, the traffic route must be used as the navigation route. In some embodiments, it may also be desirable to select in combination with some other conditions, such as: but also input information of the user, etc. In general, the maximum recommended factor for a certain transit route does not necessarily result in the transit route being a navigation route from a start position to an end position.
Further, on the basis of the above embodiment, the navigation method provided in the embodiment of the present application further includes:
and in the process of navigating according to the navigation path, performing information interaction between the mobile network with the optimal signal intensity in the mobile networks of a plurality of systems supported by the navigation device and the remote server.
It should be noted that, in the above embodiment, after the navigation path is determined, information interaction is performed between the mobile network with the optimal signal strength in the multiple systems of mobile networks supported by the navigation device on the navigation path and the remote server, and if the mobile networks with the optimal signal strength at different positions of the navigation path are different, switching is performed between the mobile networks at different positions, so that the mobile network with the optimal signal strength in the mobile network is selected to perform information interaction with the remote server.
The following describes embodiments of the apparatus provided by embodiments of the present application, which correspond to the embodiments of the method provided above. It should be noted that, for the following explanation of the related contents in the embodiments of the apparatus, reference may be made to the above-mentioned embodiments of the method.
