Description

Technical Field

[0001] The present invention relates to the field of electronic information technology, and more specifically, to a method and system for interconnecting multi-core and multi-screen mobile phones. Background Art

[0002] At present, the wireless connection between the car instrument and the mobile phone is a one-to-one connection. This is because the current mobile phones generally have only one communication module of the same type, and one communication module cannot establish a connection with multiple devices at the same time. Therefore, generally speaking, a mobile phone cannot connect to two or more devices at the same time by connecting to the instrument device in one way. The mobile phone sends or receives signals to a device alone, and the current communication is single-point. If the communication module inside the mobile phone wants to establish a connection with other instrument devices, it must first disconnect the current device and then establish a new connection.

[0003] However, the current high-end motorcycle market has put forward the demand for installing multiple display instruments on one vehicle. How to connect a mobile phone to multiple instruments at the same time and send different data information to different instruments has become a problem that needs to be solved at present. Summary of the invention

[0004] The purpose of the present invention is to provide a method and system for interconnecting a multi-core and multi-screen mobile phone. This scheme proposes that the multi-core and multi-screen system can be connected to the mobile phone for data display, and the content to be displayed can be displayed on different instrument screens respectively, thereby solving the problem that the multi-instrument system needs to switch the connection object between multiple systems when connecting to the mobile phone wirelessly, and realizing the effect of connecting multiple instruments with one meter.

[0013] Preferably, the parsing of the data information and planning of display content includes:

[0014] The main table receives data information sent by the user equipment and the vehicle body equipment, and judges the data information. If the data information is the main table display data, the main table completes the drawing and display of the data information on the main table screen after completing the data information reception; if the data information is the sub-table display data information, the main table draws it on the virtual screen, encodes the video stream, and then transmits it to the sub-table screen through the interconnection bus for display.

[0015] Preferably, the main table displays data information including vehicle speed and engine speed, and the sub-table displays data information including messages from a mobile phone, incoming call reminders, weather reminders, simple navigation, and real-time picture information from a recorder; wherein, the sub-table displays data information using a strategy combining a pre-set picture and small window drawing to display.

[0016] Preferably, when the sub-table is displayed, processing the data information and transmitting it to the sub-table screen for display includes:

[0017] The main table draws the changed content that needs to be displayed on the sub-table to the virtual screen in advance, then streams the virtual screen content, transmits it to the sub-table through the bus connection between the sub-table and the main table, and notifies the sub-table of the display location of this content, and displays it on the sub-table screen.

[0018] According to a second aspect of the present invention, the present invention provides a system for interconnecting multi-core and multi-screen mobile phones, the system comprising a main meter, a plurality of sub-meters and user equipment; wherein,

[0019] The main table is used to establish a communication connection with the user device, receive data information sent by the user device, parse the data information and plan the display content. When it is displayed as a main table, the data information is drawn and displayed on the main table screen. When it is displayed as a sub-table, the data information is processed and transmitted to the sub-table screen for display;

[0020] The user equipment is used to establish a communication connection with the master meter and send data information to the master meter;

[0024] Preferably, the main table analyzes the data information and plans the display content, including:

[0025] The main meter receives data information sent by user equipment and vehicle body equipment, and judges the data information. If the data information is data information displayed on the main meter, the main meter completes the drawing and display of the data information on the main meter screen after completing the data reception; if the data information is data information displayed on the sub-meter, the main meter draws it on the virtual screen, encodes the video stream, and then transmits it to the sub-meter screen for display through an interconnection bus such as Ethernet or ISP director.

[0026] Preferably, the main table uses a high-performance, high-frequency, multi-core CPU, and the sub-table uses a low-performance SOC with certain hardware decoding capabilities.

[0027] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0028] 1.

[0029] 2. The present invention realizes the matching of the main meter and the sub-meter. The main meter uses a high-performance chip to complete the display interface planning of all meters and the drawing of the interface to be refreshed. The sub-meter uses a low-performance chip to combine content pre-setting and small window drawing display, which not only solves the problem of poor interface drawing ability of low-performance chips, but also reduces the cost of the entire system;

[0030] 3. Since the entire system is controlled by the main meter to control the display of each sub-meter, it has a certain degree of scalability. At the same time, the number of sub-meters can be increased and decreased through the bus, realizing flexible matching of the entire system.

[0031] Other features and advantages of the present invention will be described in the following description, and partly become apparent from the description, or understood by implementing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures indicated in the description, claims and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Figure 3 The present invention is a schematic diagram of the process of interconnecting and displaying a multi-core and multi-screen mobile phone. DETAILED DESCRIPTION

[0035] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0036] refer to Figure 1 As shown, the present invention provides a method for interconnecting multi-core and multi-screen mobile phones, the method comprising the following steps:

[0037] The master table establishes a communication connection with the user device;

[0038] Receiving data information sent by user equipment;

[0039] The data information is parsed and the display content is planned. When it is displayed as a main table, the data information is drawn and displayed on the main table screen. When it is displayed as a sub-table, the data information is processed and transmitted to the sub-table screen for display.

[0040] It can be understood that the present invention proposes to project the screen of a mobile phone after the multi-core multi-screen system is interconnected with the mobile phone, and the projected content can be displayed on different screens respectively, thereby solving the problem of wireless connection of the multi-core multi-system with the mobile phone and the search problem after connection, and realizing one-core connection and multi-core display; it solves the technical problem of a mobile phone connecting to multiple instruments at the same time and sending different data information to different instruments.

[0041] Further, establishing a communication connection with the user equipment includes:

[0042] The main meter establishes a socket connection with the user device, which includes the main meter establishing a WiFi hotspot, the user device connecting to the WiFi hotspot of the main meter, and the user device transmitting data information with the main meter by pre-installing an application that matches the multi-core multi-screen system.

[0043] In this embodiment, after the multi-core multi-screen instrument system is turned on, the wifi module of the main meter will be set to AP mode, and the main meter will be used as a wifi hotspot; the user device connects to the hotspot of the main meter, and the user device pre-installs an application that matches the multi-core multi-screen system to establish a wireless connection with the main meter and transmit data information with the main meter. Specifically, the user device can be selected as a mobile phone, tablet or other mobile communication network. In this embodiment, the user device is a mobile phone.

[0044] refer to Figure 2As shown, this solution can be divided into three parts: main meter, sub-meter, and mobile phone. The sub-meter is set to one or more, and the main meter can be connected to multiple sub-meters. The mobile phone is pre-installed with an APP that matches the multi-core multi-screen system. The main meter has a wifi module and uses the AP mode of the wifi module, which has strong drawing capabilities. The wifi of the main meter is used as a hotspot, where the sub-meter is connected to the main meter via Ethernet or SPI bus, and the mobile phone is connected to the wifi module of the main meter as a client. When the main meter is successfully connected to the mobile phone, socket communication between the mobile phone and the main meter can be established through the wifi link of the wifi module.

[0045] Furthermore, the parsing of the data information and planning of display content includes:

[0046] The main table receives data information sent by the user device, and the main table parses the data information and plans the display content according to the data protocol and the filling content. If the data information is data information displayed by the main table, the main table completes the drawing and display of the data information on the main table screen after completing the data information reception; if the data information is data information displayed by the sub-table, the main table draws it on the virtual screen, encodes the video stream, and then transmits it to the sub-table through the interconnection bus.

[0047] Among them, in this embodiment, the main table displays data information including instrument contents such as vehicle speed and engine speed, and the sub-table displays data information including messages from mobile phones, call reminders, weather reminders, simple navigation, and real-time picture information from recorders; wherein, the sub-table displays data information using a strategy combining pre-set pictures and small window drawing to display.

[0048] It should be noted that the mobile phone sends data information to the main meter. If the data information is displayed on the main meter screen, the main meter can draw and display the data information on the main meter screen after receiving the data information. Considering the data transmission bandwidth limitation of the bus connection between the sub-meter and the main meter, the sub-meter display content adopts a strategy combining pre-set screen and small window drawing to display the content in consideration of the display efficiency of the sub-meter.

[0049] Furthermore, when it is a sub-table display, the data information is processed and transmitted to the sub-table screen for display, including: the main table draws the changed part of the content that needs to be displayed on the sub-table to the virtual screen in advance, and then stream media encoding the virtual screen content, transmits it to the sub-table through the bus connection between the sub-table, and notifies the sub-table of the display location of this content, and displays it on the sub-table screen.

[0050] refer to Figure 3 As shown, the process of multi-core multi-screen mobile phone interconnection display adopted by the present invention is as follows:

[0051] After the multi-core multi-screen instrument system is turned on, the WiFi module configuration program is started through the self-start mode, and the WiFi module of the main meter is set to AP mode to provide a hotspot for the mobile phone to connect;

[0052] The mobile phone connects to the hotspot of the main meter. The user establishes a socket connection with the main meter by pre-installing an APP that matches the multi-core multi-screen system. The user sets the projection display content of the main meter and the sub-meter through the pre-installed APP and usage habits. After setting and saving, the multi-core multi-screen instrument system will take effect after restarting. The projection display content of the main meter is displayed on the main meter screen, including the instrument content of vehicle speed, engine speed, etc. The projection display content of the sub-meter is displayed on the sub-meter screen, including messages from the mobile phone, call reminders, weather reminders, simple navigation, real-time images from the recorder and other information.

[0053] The APP sends data information to the main table according to user settings. Specifically, the APP sends mobile phone data information to the main table through a wifi link. The main table receives data information from the mobile phone and other sources, and plans the display content of the main table and the sub-table separately according to the user settings of the APP, and displays the display content of the main table directly on the main table screen; the display content of the main table and the sub-table includes message-based navigation data, message reminders of mobile phone applications, incoming call reminders, weather data, etc., and the data information from other sources includes engine speed, vehicle speed, fuel level, and camera image.

[0054] According to the above user settings, the main table draws the changed part of the content that needs to be displayed on the sub-table to the virtual screen in advance, then streams the virtual screen content, transmits it to the sub-table through the bus connection between the sub-table, and notifies the sub-table of the display location of this content, and displays it on the sub-table.

[0055] Furthermore, considering the limitation of system cost, the main table uses a high-performance, high-frequency, multi-core CPU, and the sub-table uses a low-performance SOC with certain hardware decoding capabilities. The sub-table uses a low-performance SOC, so its interface drawing capability is limited. This solution combines content pre-setting and small window drawing display on the sub-table, solidifies the background UI and other displays, and displays the display screen encoded by the main device from the data bus at the specified position of the sub-table. Therefore, by adopting a SOC with certain hardware decoding capabilities, the sub-table can display the active screen from the main table while consuming less performance. In this way, flexible interface customization capabilities can be achieved even when the performance of the sub-table is weak.

[0056] According to a second aspect of the present invention, the present invention provides a system for interconnecting multi-core and multi-screen mobile phones, the system comprising a main meter, a plurality of sub-meters and user equipment; wherein,

[0057] The main table is used to establish a communication connection with the user device, receive data information sent by the user device, parse the data information and plan the display content. When it is displayed as a main table, the data information is drawn and displayed on the main table screen. When it is displayed as a sub-table, the data information is processed and transmitted to the sub-table screen for display;

[0058] The user equipment is used to establish a communication connection with the master meter and send data information to the master meter;

[0059] The sub-meter is used to receive data information transmitted by the main meter and display it on the sub-meter screen.

[0060] Further, the main table, used to establish a communication connection with a user device, includes:

[0061] The main meter establishes a socket connection with the user device, wherein the main meter establishes a WiFi hotspot, and the user device connects to the WiFi hotspot of the main meter. The user device transmits data information with the main meter by pre-installing an application that matches the multi-core multi-screen system.

[0062] Furthermore, the parsing of the data information and planning of display content includes:

[0063] The main table receives data information sent by the user device and judges the data information. If the data information is data information displayed by the main table, the main table completes the drawing and display of the data information on the main table screen after completing the data reception; if the data information is data information displayed by the sub-table, the main table draws it on the virtual screen, encodes the video stream, and then transmits it to the sub-table screen through the interconnection bus for display.

[0064] Considering the limitation of system cost, the main table uses a high-performance, high-frequency, multi-core CPU, and the sub-table uses a low-performance SOC with certain hardware decoding capabilities. Therefore, its drawing and display capabilities are limited. This solution combines content presetting and small window drawing and display on the sub-table, which not only solves the problem of insufficient performance of the sub-table but also takes into account the needs of some customized display drawing.

[0065] It can be understood that the system for interconnecting multiple cores and multiple screens mobile phones provided by the present invention corresponds to the method for interconnecting multiple cores and multiple screens mobile phones provided in the aforementioned embodiments. The relevant technical features of the system for interconnecting multiple cores and multiple screens mobile phones can refer to the relevant technical features of the method for interconnecting multiple cores and multiple screens mobile phones, which will not be repeated here.

[0066] In summary, the entire system of the present invention uses a combination design of a main table and sub-tables, which realizes the flexible configuration of sub-tables that can be increased or decreased according to project needs; the APP sends data information to the main table according to user settings, and the main table uses a high-performance, high-main table, multi-core CPU. After receiving and parsing data information through the main table, the display of the main table and the sub-table are realized according to the data protocol and filled content; the sub-table is combined with content pre-setting and small window drawing display, which not only solves the problem of insufficient performance of the sub-table but also takes into account the needs of some customized display drawing. The entire system proposes a one-core connection and multi-core display, which simplifies the user connection operation.
