Embodiment 1

[0025] Please check figure 1 , the map data update method that the first embodiment of the present invention proposes, be applied in a vehicle-mounted computer, described vehicle-mounted computer comprises WinCE equipment and Android board card, is provided with GPS chip in the described WinCE equipment, described method comprises the following step:

[0026] Step S101, the Android board acquires the current NMEA positioning data of the on-board computer from the WinCE device.

[0027] Among them, because the on-board computer is equipped with a GPS chip, the GPS chip is integrated with navigation software (map software) to receive the data transmitted by the satellite and display the map or waypoint track information, and store the data transmitted by the satellite as the current NMEA positioning The data is stored in the on-board computer. When in use, set an Android board integrated with the installation system and connect to the on-board computer through the communication...

Embodiment 2

[0036] see figure 2 , the map data updating method that the second embodiment of the present invention provides is applied in a vehicle-mounted computer, and described vehicle-mounted computer comprises WinCE device and Android board card, and described Android board card comprises virtual GPS serial device, GPSHAL layer and frameworks layer, The method includes the following steps:

[0037] Step S201, the Android board reads the serial port data encapsulated in the on-board computer.

[0038] Through the above steps, the current NMEA positioning data can be obtained, wherein the current NMEA positioning data is the data received by the GPS chip from the satellite, and the current NMEA positioning data in the GPS chip is read by the WinCE device in the vehicle-mounted computer. Specifically, the WinCE device and the Android board are connected through the communication serial port, but the current NMEA positioning data cannot be directly transmitted through the communication...

Embodiment 3

[0051] see image 3 , a kind of map software updating system that the third embodiment of the present invention provides, comprises WinCE equipment 10 and Android board 20, described WinCE equipment connects Android board 20 through a communication serial port data line 30, and Android board 20 passes through An RGB data line 40 is connected with the display screen in the WinCE device 10, wherein: the Android board 20 is used to obtain the current NMEA positioning data of the vehicle-mounted computer from the WinCE device 10; and analyze the current NMEA positioning data, To obtain the current map information; the Android board 20 is provided with a map navigation application program, and the map navigation application program is used to update the current map information, so as to update the current map information to display map information, And the displayed map information is sent to the display screen of the WinCE device 10 for display.

Abstract

The invention provides a map data updating method and system, a readable storage medium and a computer device. A WinCE device obtains the satellite data in real time, and the Android board obtains thecurrent NMEA positioning data in the WinCE device, and analyzes the current NMEA positioning data through the Android board to obtain the current map information; the Android board uses its own map navigation application to update the current map information through, to update the current map information to display map information, and sends the display map information to the WinCE device for display, wherein the Android board can receive the current NMEA positioning data in the WinCE device; the data processing hardware and the display hardware of the vehicle-mounted computer are fully utilized, and the complexity of hardware design is reduced. The map navigation application program is updated accord to the current NMEA positioning data, the vehicle-mounted computer displays the map information according to the display map information in the map navigation application program, and normal navigation is realized.

Description

technical field [0001] The invention relates to the technical field of vehicle multimedia, in particular to a map data update method, system, readable storage medium and computer equipment. Background technique [0002] In some countries, the on-board electronic system (on-board computer) generally uses WinCE devices instead of Android devices. [0003] The navigation software on the existing WinCE equipment, because the supplier of the WinCE equipment suspends maintenance, so the navigation software in the vehicle computer cannot automatically update the map information, and the map information will change over time, such as the map information cannot be timely Update, the user will drive to the wrong road due to choosing the wrong map information, which may lead to getting lost, or seriously threaten the user's personal safety and property safety, and the user experience is poor. Contents of the invention [0004] The purpose of the present invention is to provide a map...
