Further, as shown in FIG. 3, in the above-mentioned step S12, the navigation path is determined in the passing path according to the path parameters of each passing path and the signal strength of the optimal mobile network corresponding to each passing path, which may specifically include the following steps:

S121. Divide each passing path into multiple path units.

Specifically, when any passing path is divided into multiple path units in step S121, the division can be based on the signal strength of the mobile network signal, or can be divided based on the distance. When dividing based on the signal strength of the mobile network, if the signal strength of the best mobile network among the signal strengths of the mobile networks of the multiple standards supported by the navigation device in one section of the travel route is the same or approximately the same, then the A road section is divided into a path unit; when dividing based on distance, road sections with the same distance and length within a passing path can be divided into a path unit.

Exemplarily, as shown in FIG. 4, there are two paths (41, 42) from the start position S to the end position E in FIG. The path unit 421 and the path unit 422 are taken as examples for description. The navigation device supports the mobile network of the first standard and the mobile network of the second standard. The signal strength of the mobile network of the first standard on the path unit 411 is A ₄₁₁₁ , and the signal strength of the mobile network of the second standard on the path unit 411 is A ₄₁₁₂ , the signal strength of the mobile network of the first standard on the path unit 412 is A ₄₁₂₁ , the signal strength of the mobile network of the second standard on the path unit 412 is A ₄₁₂₂ , the mobile network of the first standard on the path unit 421 The signal strength of the mobile network of the second standard on the path unit 421 is A ₄₂₁₁ , the signal strength of the mobile network of the second standard on the path unit 421 is A ₄₂₁₂ , the signal strength of the mobile network of the first standard on the path unit 422 is A ₄₂₂₁ , and the second standard on the path unit 422 The standard mobile network signal strength is A ₄₂₂₂ .

S122. Obtain the signal strength of the optimal mobile network corresponding to each path unit.

The optimal mobile network corresponding to each path unit refers to the optimal mobile network among the signal strengths of mobile networks of multiple standards supported by the navigation device.

Specifically, in the above-mentioned embodiment shown in FIG. 4 , when A ₄₁₁₁ >A ₄₁₁₂ , the signal strength of the optimal mobile network corresponding to path unit 411 is A ₄₁₁₁ ; when A ₄₁₁₁ <A ₄₁₁₂ the optimal signal strength of the path unit 411 is The signal strength of the mobile network is _A4112 ; when _A4121 > _A4122 , the signal strength of the optimal mobile network corresponding to the path unit 412 is _A4121 ; when _A4121 < _A4122 , the optimal mobile network corresponding to the path unit 412 The signal strength of A ₄₁₂₂ ; when A ₄₂₁₁ >A ₄₂₁₂ , the signal strength of the optimal mobile network corresponding to the path unit 421 is A ₄₂₁₁ ; when A ₄₂₁₁ <A ₄₂₁₂ the signal strength of the optimal mobile network corresponding to the path unit 421 is A ₄₂₁₂ ; when A ₄₂₂₁ >A ₄₂₂₂ , the signal strength of the optimal mobile network corresponding to the path unit 422 is A ₄₂₂₁ ; when A ₄₂₂₁ <A ₄₂₂₂ , the signal strength of the optimal mobile network corresponding to the path unit 422 is A ₄₂₂₂ .

S123. Obtain the signal strength of the optimal mobile network corresponding to each passing path according to the signal strength of the optimal mobile network corresponding to each path unit.

Specifically, when the traffic 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 traffic path is obtained according to the signal strength of the mobile network on each path unit, which may specifically be:

I. Obtain the weight of the path unit according to the length of each path unit and the total path length.

For example: the total length of the path 41 is 100m, the length of the path unit 411 is 60m, and the length of the path unit 412 is 40m, then the weight of the path unit 411 is 0.6, and the weight of the path 412 is 0.4.

II. Obtain the signal strength of the optimal mobile network corresponding to each passing path according to the signal strength of the optimal mobile network corresponding to each path unit and the weight of the path unit.

As above, the weight of the path unit 411 is 0.6, the weight of the path 412 is 0.4, the signal strength of the optimal mobile network corresponding to the path unit 411 is A ₄₁₁₁ , and the signal strength of the optimal mobile network corresponding to the path unit 412 is A ₄₁₂₂ , then The signal strength of the optimal mobile network corresponding to the passage 41 is: A ₄₁ =0.6*A ₄₁₁₁ +0.4*A ₄₁₂₂ .

When the traffic path is divided into path units based on the path length, the signal strength of the optimal mobile network corresponding to each path unit is obtained according to the signal strength of the optimal mobile network corresponding to each path unit, which can be specifically:

The average value of the signal strength of the mobile network on each path unit is used as the signal strength of the optimal mobile network corresponding to each passing path.

For example: the total length of path 42 is 100, the length of path unit 421 is 50, the length of path unit 422 is 50, the signal strength of the mobile network on path unit 421 is A ₄₂₁₁ , the signal strength of the mobile network on path unit 422 is A ₄₂₂₂ , then the signal strength of the mobile network on path 42 is A ₄₂ =(A ₄₂₁₁ +A ₄₂₂₂ )/2.

S124. Determine a navigation route among the travel routes according to the route parameters of each travel route and the signal strength of the optimal mobile network corresponding to each travel route.

Further, the embodiment of the present application provides an implementation method of determining a navigation route in the travel route according to the path parameters of each travel route and the signal strength of the optimal mobile network corresponding to each travel route in step S12. Specifically, as shown in Figure 5, the method includes the following steps:

S51. Calculate and calculate the recommendation factor of each passing route according to the formula f _i =A _i *x+(1-x)*B _i .

Among them, f _i is the recommendation factor of the path i, A _i is the signal strength of the optimal mobile network corresponding to the path i; B _i is the traffic condition parameter of the path i, and x is a constant greater than 0 and less than 1.

Wherein, the traffic condition parameters of the passing route may be calculated and obtained according to one or more of the information such as the length of the passing route, the degree of congestion, the road condition of the route, and the weather conditions on the route. And when the length of the route is shorter, the congestion degree of the route is lower, the road condition of the route is better, and the weather condition on the route is better, the corresponding road condition parameter is larger.

Exemplarily, referring to FIG. 6 , the process of calculating the recommendation factor of each passing path in the above embodiment is illustrated by taking the road condition parameter of the passing path calculated and obtained according to the length of the passing path and x=0.1 as an example. As shown in FIG. 6, there are two passing paths (61, 62) from the starting position S to the ending position E. Wherein, the length of traffic path 61 is: 10 kilometers (km), the length of traffic path 62 is: 15 kilometers (km), then the road condition parameter B ₆₁ of traffic path 61 can be the total length of all traffic paths and the traffic path The difference of the length of 61, i.e. B ₆₁ =(10+15)-10=15; similarly, the road condition parameter B ₆₂ of the passage path 62 can be the difference between the total length of all passage paths and the length of the passage path 62, i.e. B ₆₂ =(10+15)-15=10. In addition, the signal strength A ₆₁ of the optimal mobile network corresponding to the path 61 is -100 dBm, and the signal strength A ₆₂ of the optimal mobile network corresponding to the path 62 is -110 dBm. The formula for calculating the recommended factor mentioned above is as follows:

The recommendation factor of the passing route 61 is:

f ₆₁ ＝A ₆₁ *x+(1-x)*B ₆₁ ＝100*0.1+(1-0.1)*15＝23.5;

The recommendation factor of the passing route 62 is:

f ₆₂ =A ₆₂ *x+(1-x)*B ₆₂ =110*0.1+(1-0.1)*10=20.

It should be noted that, in the above embodiment, there are two paths from the starting point to the end point for illustration, but the embodiment of the present application is not limited thereto. In the actual navigation process, the path from the starting point to the end point may include More passing paths, for example: 3, 4, 10 etc., but the calculation process of the recommendation factor of each path is the same as the calculation process of the recommendation factor of the above-mentioned passing path 31 or passing path 32, for avoiding repeating, no longer Detailed description.

It should also be noted that, in the calculation formula of the above recommendation factor, x is the weighting factor of the signal strength of the optimal mobile network corresponding to the passing path, and 1-x is the weighting factor of the road condition parameter. The x value can be set according to the influence of the signal strength of the mobile network on the path on the navigation. For example: when the above navigation method is used for self-driving vehicles or blind-guiding robots, if the signal strength of the mobile network is too weak, it may lead to situations such as vehicle loss of control and blind people getting lost, so the above-mentioned navigation method is used for self-driving vehicles or blind-guiding robots When the x value can be set larger. Another example: when the above navigation method is used for normal navigation, when the signal strength of the mobile network is weak, no serious consequences will be caused, so the value of x can be set to be smaller at this time.

S52. Selecting the passage route with the largest recommendation factor as the navigation route.

Exemplarily, in the above-mentioned embodiment shown in FIG. 6 , the recommendation factor f 61 of the passage ₆₁ =23.5, the recommendation factor f 62 of the passage ₆₂ =20, f ₆₁ =23.5>f ₆₂ =20; so the selection of the passage 61 As a navigation route from the start position S to the end position E. In addition, in some embodiments, there may be a situation where the recommendation factors of the two travel routes are equal and the largest, and at this time, any one of the two travel routes with the largest recommendation factor can be selected as the navigation route.

It should also be noted that, in the above embodiment, the route with the largest recommendation factor is selected as the navigation route, and it does not mean that when the recommendation factor of a certain route is the largest, the route must be used as the navigation route. In some embodiments, it may also need to be selected in combination with some other conditions, for example, it is also necessary to refer to user input information and the like. In general, the maximum recommendation factor of a certain path does not necessarily lead to the path being used as a navigation path from the starting point to the end point.

Further, on the basis of the above-mentioned embodiments, the navigation method provided in the embodiments of the present application further includes:

During the navigation process according to the navigation route, the mobile network with the best signal strength among the mobile networks of multiple standards supported by the navigation device performs information exchange with the remote server.

It should be noted that, in the above embodiment, after the navigation route is determined, the mobile network with the best signal strength among the mobile networks of multiple standards supported by the navigation device on the navigation route performs information exchange with the remote server. The mobile network with the best signal strength in different locations is different, and the mobile network is switched between different locations, so as to select the mobile network with the best signal strength in the mobile network to perform information interaction with the remote server.
