1 is a flow diagram of a computer program for navigation in accordance with an embodiment of the present invention. The computer program is stored in the memory 11. When the computer program is executed by the processor 12, the following steps are implemented:

S101: The navigation module in a mobile terminal acquires a positioning location.

The navigation module is a software module disposed in the mobile terminal, and can process and calculate geographic location information, and provide navigation information for the user. In this embodiment, the navigation module itself does not have a positioning function, and the positioning position must be obtained from other modules having a positioning function. Other modules can achieve positioning by means of GPS positioning, Beidou positioning, mobile cellular network base station assisted positioning, and wifi access point positioning. The GPS positioning and the Beidou positioning method are all located by signals transmitted by the positioning satellites surrounding the earth, and the signals sent by the positioning satellites are received by the GPS module or the Beidou positioning module; the mobile terminal communicates with the mobile cellular network through the base station. The communication module inside the mobile terminal can be realized, and most of the base stations have fixed positions, and the base station accessed by the mobile terminal can determine the location range thereof. The positioning accuracy of this method is lower than GPS positioning and Beidou positioning. Each wifi access point accesses the Internet through its bound broadband or fiber-optic account, and the network operator can know the address of the account and obtain its location. Since the user uses the navigation function, it is often outdoors, and is connected via wifi. Inbound location It is rarely used. The navigation module acquires a positioning location of the mobile terminal from a module having a positioning function through a corresponding data interface.

S102: The navigation module calculates a navigation path according to the destination set by the user and the positioning position.

The navigation module in this step performs a navigation path calculation function. Map information is recorded in the navigation module, and the map information mainly includes road information, geographic identification information, and location coordinates of the information. Before the navigation module performs the calculation, the user also needs to input a destination, which should be one of the pre-recorded geographical indications in the navigation module. The navigation module calculates a navigation path between the positioning location and the destination by using a navigation algorithm. In the navigation algorithm, a directed graph is used to represent each geographic identifier in the map and a distance between the geographic identifiers. Then, using the geographical indication of the location location as a starting point, and performing the optimal path calculation with the geographic identifier of the destination as the end point, all the paths connecting the positioning location and the destination may be traversed to find out all the paths. The shortest path in , using the shortest path as the navigation path. In other implementation manners of the present application, different navigation paths may be displayed on the navigation interface to support the user to select a preferred path; the navigation module may also perform navigation path calculation according to time priority and distance priority, and distance priority The calculation method has been described above. When calculating the time-prioritized navigation path, the time interval corresponding to the time zone and the road condition of each road on which the path is located is pre-stored in the storage medium, and then the distance of all the roads included in each path is divided by the corresponding At the speed of time, the obtained quotient is accumulated to obtain the time of the path, and finally the path with the least time is found as the navigation path.

S103: The navigation module determines a forward direction of the next step according to the positioning position and the navigation path.

In this step, the direction of the forward direction is determined. The navigation path is often composed of a plurality of road sections, and the steering needs to be made at the junction of different roads, or some roads are not straight lines, and need to be biased in a certain direction to advance. In this step, the forward direction of the next step is determined on the basis of the positioning position and the navigation path. For example, the front is the intersection, and the next segment of the navigation path is the road perpendicularly intersecting the current road segment to the right, and the next forward direction is rightward. Turn 90°. When determining the forward direction, an advance amount may be set for the subsequent navigation path, for example, the difference between the direction of the road where the navigation path is located after 10 meters and the direction of the current navigation path is determined, and the difference is used as the forward direction. The direction of each road is recorded in the storage medium in the form of a vector, so that the angle of the different roads can be obtained by vector calculation, thereby obtaining the heading direction. In practical applications, most of the cases are intersections. If you need to turn left or right, they are all 90° forward.

S104: Display the forward direction on a full screen of the display interface of the mobile terminal.

This step includes important technical features that are different from the prior art, that is, the forward direction is displayed on the display interface in full screen, and the traditional navigation interface is no longer displayed, that is, the map information and the navigation path information are not displayed, and only the indication is displayed. The logo of the direction of advancement, such as arrows, pointers, etc., the background can be selected with a simple solid color image, This highlights the direction of advancement. Displaying the forward direction in full screen can facilitate the user to visually see the forward direction of the next step, without distracting attention to which position on the navigation path the current position is, just follow the direction of the forward direction, and shorten the acquisition of navigation information. time. For example, if the next direction of advance is to turn left at the intersection, the arrow pointing to the left is displayed, indicating that the next approach direction is 90° left. The forward direction may be any angle between 0-180°, depending on the actual situation of the navigation path.

S105: The speaker of the mobile terminal issues a voice prompt.

Since the user often needs to pay attention to the road situation when moving, especially when driving, it is difficult to distract the navigation information, so the voice prompt is required to provide an auxiliary prompt. The step of step S104 and the full-screen display forward direction together constitute a navigation prompt, and the user can see whether the upcoming forward direction needs to be turned by looking at the display interface, and the speaker of the mobile terminal emits a prompt sound to help the user confirm. Judge to make subsequent reaction actions. For example, when the next forward direction is the intersection to the right, the display interface displays an arrow pointing horizontally to the right, indicating that the next turn is to the right, and the processor controls the speaker to emit a prompt tone. Please turn right 90°". Different voice prompts can be set for different heading directions.

As a further improvement of the computer program, when the step S101 is performed, the positioning position is acquired by the GPS module in the mobile terminal. The preferred embodiment optimizes the manner in which the location is acquired, that is, the GPS location mode. The GPS module is disposed in the mobile terminal, and performs positioning work by connecting with a GPS network, where the GPS network is composed of multiple GPS satellites, and is connected with a device having a GPS module on the ground, and sends a signal to the GPS module. , to assist in its positioning.

As a further improvement of the above computer program, the GPS module refreshes the positioning position according to a first period preset in the storage medium. Since the position of the mobile terminal is constantly changing when the user holds the mobile terminal, the positioning position acquired at a certain time cannot represent the real position of the next time period after a certain period of time, and therefore the positioning position is required. The refresh is performed, and the refresh frequency is in accordance with a first period preset in the storage medium. The first period is preferably at least 1 second. If the first period is set too long, the positioning of the mobile terminal is lagging behind, the navigation effect is also delayed, and the experience is not good; if the first period is set Too short, the resources of the mobile terminal are too expensive, especially the processor and the GPS module are in a high-load working state, and occupy resources of other tasks. In combination with the above considerations, the first period is preferably at least 1 second, and even if the user is in the car, the fastest movement of 30 meters per second, the refreshing of the positioning position in one second does not affect the navigation effect.

As a further improvement of the above computer program, when the navigation module of the mobile terminal acquires a positioning location, the positioning is assisted by the mobile cellular network. The mobile terminal selectable positioning manner further includes mobile cellular network positioning, and when the user is in a position where the building is blocked or the vehicle is blocked, the signal of the GPS module may be affected, resulting in no The method is precisely positioned by GPS, so an alternative method is needed to assist positioning, and a mobile cellular network is one of them. China's mobile cellular network coverage is already very high, and the main roads and residential areas have signal coverage, so mobile cellular networks can be used for auxiliary positioning. The communication module of the mobile terminal is connected to a nearby mobile base station, and the location of the base station is often fixed and known, so the approximate location of the mobile terminal can be determined in this manner. When the mobile terminal is being positioned by the GPS module or the Beidou positioning module, the mobile cellular network can also be used for assistance at the same time, and the positioning position confirmation is performed together, so that the positioning reliability is higher.

As a further improvement of the above computer program, when step S104 is executed, an arrow indicating the heading direction is displayed on the display interface, and the arrow tail is disposed at the center or the bottom of the display interface. The preferred embodiment is preferred for the display form of the advancement direction, with arrows indicating the direction of advancement. Since the arrow has a head and a tail and has directional directivity, it can indicate the direction. The tail of the arrow is disposed at the center or the bottom of the display interface. When the tail of the arrow is disposed at the center of the display interface, a certain direction may be indicated like a clock pointer according to an actual situation; when the arrow is When the tail is provided at the bottom of the display interface, a rotation direction of up to 90° is displayed to the left or right.

As a further improvement of the above computer program, the display interface displays a navigation path in the forward direction according to a distance preset within the storage medium. In this embodiment, in addition to displaying the forward direction, the display interface further displays a navigation path, where the length of the navigation path is preset to be within the storage medium, and the distance is preferably 50-200 meters. Considering that some users still maintain the navigation information reading habits in the prior art, the preferred embodiment displays a navigation path of a distance in the forward direction, so that the user can know the association between the forward direction and the next navigation path. Instead of leaving the road out of thin air to find the way forward.

Referring to FIG. 1 and FIG. 2, FIG. 1 is a schematic diagram of a specific process of step S105 in FIG. 1 according to an embodiment of the present invention. Before the step S101, the computer program includes the following steps:

S100: pre-storing voice information corresponding to different forward directions in the storage medium.

The forward direction may be various, such as leftward, rightward, tumbling, straight, etc.; the forward direction may also include an angle value, such as a left turn of 90 degrees, a right turn of 30 degrees, and the like. Different directions of advancement should correspond to different voice information in order to provide corresponding prompts. The forward direction and voice information may be stored in the storage medium in groups, and the forward direction and the voice information in the same group correspond to each other. The voice information may be an audio file, each voice information being in a separate format may be in a format readable by the computer program, such as mp3, mp4, wav, wma, and the like. The forward direction may be stored in the storage medium in a text manner; when the forward direction includes an angle value, the recording is incrementally increased by 10°, that is, left turn 10°, left turn 20°, left turn 30° ...turn left 170°, the same voice information is recorded, covering all steering angles.

The step 105 includes:

S105-1: Select corresponding voice information according to the forward direction.

In this step, the corresponding voice information is selected from the storage medium according to the forward direction determined in step S103, that is, the text in the forward direction pre-stored in the storage medium is compared with the text in the forward direction determined in step S103, and the same is found. After the forward direction text, the voice information stored in the same group is acquired.

S105-2: The speaker plays the voice information.

This step plays the voice information selected in step S105-1, and the speaker converts the voice information into a sound wave signal.

Referring to FIG. 3, which is a schematic flowchart of a computer program for navigation according to another embodiment of the present invention, after the step S105', the computer program further includes the following steps:

S106: Determine whether the mobile terminal arrives at the destination.

The manner of determining whether the mobile terminal arrives at the destination is to determine whether the location location coincides with the destination, and if the two coincide, the mobile terminal arrives at the destination. Since the positioning always produces an error, a certain deviation threshold can be allowed, that is, when the distance between the positioning position and the destination is within the deviation threshold range, the mobile terminal is regarded as reaching the destination.

When the mobile terminal does not reach the destination, repeating the foregoing steps according to a second period preset in the storage medium, refreshing and displaying the forward direction and issuing a voice prompt. The implication of this operation is that navigation is an iterative and repetitive process. It only needs to locate and calculate the navigation path once and can not meet the navigation requirements of the whole process. If the user's position changes or does not move according to the established navigation path, it needs to be repositioned. And calculate the navigation path. When the mobile terminal is in different positioning positions, the forward direction is continuously determined, and the display of the forward direction on the display interface is refreshed, and the latest voice prompt is synchronized. The second period is preferably from 1 minute to 5 minutes. If the second period is too long, the navigation effect is delayed; if the second period is too short, voice prompts are frequently issued to cause interference to the user. In other embodiments of the present application, the positioning position acquisition and the navigation path calculation may be performed in a shorter second period. If the forward direction is the same as the current moving direction, the display interface is not refreshed, and no voice prompt is issued. Or, according to a long period, a voice prompt of "Please keep straight" is issued; if it is judged that the forward direction is different from the current moving direction, the display interface is refreshed and a voice prompt is given.

When the mobile terminal arrives at the destination, the navigation ends. When the navigation is finished, the positioning position is not acquired, and the navigation path is no longer calculated. The prompt of the navigation end may be displayed on the display interface, or the voice prompt navigation may end.
