step S10, acquiring the interface attribute of the display screen 210;

step S20, acquiring navigation information of the mobile terminal 100;

step S30, converting the navigation information into a virtual screen matched with the interface attribute;

step S40, and displaying a virtual screen on the display screen.

In this embodiment, the meter 200 should be provided with a display screen, which can be dedicated to navigation display or be reused with other driving information, especially for use in a motorcycle, for example, the motor temperature data, the vehicle speed, the acceleration, the tire pressure, the driving mileage, etc. can be obtained through the display screen, and the navigation display is performed through the display screen, and the driver performs driving operation according to the navigation information or the navigation path. And, the simple instrument 200 sets up the high-accuracy navigation system, with high costs and if adopt the mobile network still need pay the flowrate expense in addition, the structure is complicated and unstable, need to embed various module, user's interest and attractiveness are extremely bad, the invention provides the instrument 200 based on mobile terminal 100 and shows the scheme of the intelligent navigation, namely utilize the convenient condition of the innate of the mobile terminal 100 to carry on the high-accuracy navigation, share the navigation information to the display screen 210, can realize the instrument 200 and show the navigation, can also realize the resource sharing, reduce the instrument 200 cost, improve the market competitiveness.

Meanwhile, while navigation sharing is performed, effective compatibility needs to be performed on the display attributes of the mobile terminals 100 of different users, for example, a mobile phone, the meter 200 may be used with different mobile terminals 100, that is, instead of screen projection of a pure display screen, the interface attribute of the display screen 210 is first obtained through step S10, the preferred interface attribute is an interface display size, the navigation information of the mobile terminal 100 is obtained through step S20, the navigation information is converted into a virtual screen matched with the interface attribute according to a preset rule, and the virtual screen is displayed on the display screen, so that the display screen 210 can be used with different mobile terminals 100 in a compatible manner, and all correct screens can be displayed on the display screen 210.

The establishment of the virtual screen comprises the following steps: presetting a virtual screen template, and setting the interface size of the virtual screen template and the change of related characters, symbols and images by combining interface attributes; and then, the navigation information is imported into the virtual screen template, the virtual screen template selects the required navigation information, the templated virtual screen template is changed into a real-time dynamic virtual screen, and the virtual screen is projected on the display screen 210 for effective display.

In this embodiment, the processing step of converting the navigation information into the virtual screen matched with the interface attribute includes two schemes.

In the first scheme, the mobile terminal 100 converts the navigation information into a virtual screen matched with the interface attribute, and sends the virtual screen to the display screen, and the virtual screen is displayed on the display screen.

And in the second scheme, the mobile terminal 100 sends the navigation information to the display screen, and the display screen converts the navigation information into a virtual screen matched with the interface attribute and displays the virtual screen.

The two schemes are roughly processed in the same way, and the difference lies in the establishment position and the establishment time of the display screen. In the first scheme, all processing is implemented on the mobile terminal 100 to form a virtual screen which can be displayed on the display screen, the advantages of the hardware conditions of the mobile terminal 100 are utilized to greatly reduce the hardware requirements required by the instrument 200, the cost of the instrument 200 is reduced again, and the instrument 200 is suitable for various occasions, for example, the instrument 200 can be installed on a conventional two-wheel electric vehicle, and of course, vehicles which can walk such as motorcycles, bicycles, cars and the like can also be installed. And the second scheme does not need too many operations of parameters of the mobile terminal 100, and only needs to acquire and send data to the instrument 200, and the instrument 200 can form a corresponding virtual screen according to preset parameters and rules and effectively display the virtual screen.

The open SDK module is also called a software development kit, and is generally a set of development tools used by some software engineers to establish application software for a specific software package, a specific software framework, a specific hardware platform, a specific operating system, and the like. It may simply be a file that provides an application program interface API for a certain programming language, but may also include complex hardware that can communicate with a certain embedded system. Typical tools include utility tools for debugging and other purposes. SDKs also often include example code, supporting technical notes, or other supporting documentation to clarify suspicions for basic reference.

Preferably, the open type SDK module is a Baidu open type SDK module or a Goods open type SDK module, and performs data acquisition according to a corresponding navigation program to acquire data generated and required in the navigation operation. The method has the advantages that due to the integration of the open SDK, research and development personnel can customize the functions to be developed, the method is flexible and convenient, and the method does not need to rely on third-party interconnection apps, so that the cost is saved.

In step S222 and step 2223, there are two sets of processing scenarios.

step S33, encoding the virtual screen to form a data packet;

and step S34, the display screen decodes the data packet to form a virtual screen.

Among them, the API (Application Programming Interface) is some predefined interfaces (such as function and HTTP Interface), or refers to the convention for linking different components of the software system. To provide a set of routines that applications and developers can access based on certain software or hardware without accessing source code or understanding the details of the internal workings.

The virtual screen is created through a system API, namely, data corresponding to navigation contents in the navigation program are synchronized to the virtual screen through the system API directly or after being processed through a preset rule program, namely, the corresponding navigation contents are loaded into the space establishing program of the virtual screen to form the real-time virtual screen.

Such as intra-frame prediction compression, the spatial domain data redundancy problem is solved. Such as inter-frame prediction compression (motion estimation and compensation), the problem of time domain data redundancy is solved. Such as an integer Discrete Cosine Transform (DCT), the spatial correlation is transformed into frequency-domain independent data and then quantized. Such as CABAC compression.

Data transmission is carried out in a mode of encoding into H264 data, effective transmission is carried out between the mobile terminal 100 and the meter 200, and transmission efficiency and data integrity are improved. Data Encapsulation (Data Encapsulation), which in general terms is to map service Data into the payload of a certain Encapsulation protocol, then fill the packet header of the corresponding protocol to form the Data packet of the Encapsulation protocol, and complete rate adaptation.

Among them, the Transmission Control Protocol (TCP) is a connection-oriented, reliable, byte stream-based transport layer communication Protocol, defined by RFC 793 of IETF, and the Internet Protocol suite supports a connectionless transport Protocol called User Datagram Protocol (UDP). UDP provides a way for applications to send encapsulated IP packets without establishing a connection.
