Abstract
The invention discloses an ARM-based GPS in-vehicle navigation system. According to the ARM-based GPS in-vehicle navigation system disclosed by the invention, an embedded ARM processor is used as a core, open source Linux is used as an operating system, a GPS module is used to communicate with a hardware platform, and interface development is performed through the last Qt/E, so as to design and implement the in-vehicle navigation system.
Description
Technical field
The invention belongs to vehicle mounted guidance technical field, and in particular to based on the Hardware platform design of the onboard navigation system of ARM,
Gathered based on the foundation of the onboard navigation system Software for Design platform of Linux, Qtopia Design of Graphical Interface, gps data and fixed
The technologies such as position.
Background technology
Now the onboard navigation system used by China has following several big problems：First, although China from the vehicle of external import plus
Fill onboard navigation system, but their all not subsidiary China Electronics's maps, and also the problem without Chinese interface more dashes forward
Go out.Second, present onboard navigation system is based on independent navigation, and automobile navigation would is that with the trend that monitoring unites two into one
The general orientation of production development；3rd, it is expensive, and also versatility and compatibility are all poor.4th, present vehicle mounted guidance system
, without excessive input in the core technologies such as hardware and software, correlation is also very not enough with suit, and follow-up service will also collect price for system
High expense.
The content of the invention
In order to overcome the problems referred to above, the onboard navigation system of patent of the present invention be integrated with embedded technology, computer operating system,
Modern communication technology, navigator fix technology etc., with embedded ARM processor as core, with open source linux as operating system,
Communicated with hardware platform using GPS module, and interface development is carried out by last Qt/E, to set to onboard navigation system
Meter.This product has the advantages that low cost, low in energy consumption, performance be strong, practicality is high.
The technical solution adopted in the present invention is：
The development platform of processor S3C2440A and (SuSE) Linux OS using based on ARM9 of the invention main, from hardware and
Two aspects of software are designed onboard navigation system, mainly there is the following aspects：
(1) hardware platform of onboard navigation system, including onboard navigation system master are built as core with S3C2440A microprocessors
The design of the peripheral module wanted.Onboard navigation system is mainly by message processing module, gps signal acquisition module and man-machine interaction mould
Block etc. is constituted, and each peripheral module includes power supply, display, memory, serial ports etc..
(2) Software for Design platform is built for onboard navigation system.It is included in embedded Linux system development environment on host
Foundation, foundation of cross compilation environment etc., are mainly the transplanting of linux system on target machine.
(3) application program of onboard navigation system is have developed under (SuSE) Linux OS environment.Including the collection of gps signal
Interface is developed with process, with Qt/E, and realizes the function of onboard navigation system.
Compared with prior art, the invention has the beneficial effects as follows, whole system fully according to China use habit autonomous Design,
The system is more suitable for more perfect in China Navigater, follow-up service, and employ embedded technology, make cost it is lower,
Power consumption is lower, performance is higher, practicality is higher.Hardware leaves the interface of abundance, in subsequent use, can add as needed
Plus some functions, extensibility is strong.
Description of the drawings
Fig. 1 is onboard navigation system hardware overall framework schematic diagram.
Fig. 2 is onboard navigation system software overall framework schematic diagram.
Specific embodiment
Below in conjunction with the accompanying drawings the present invention is further described.
In FIG, GPS navigation system first has to receive satellite-signal by gps receiver (3), then using the micro- places of ARM
Reason device (1) parses corresponding position data and carries out data processing, current to show in electronic chart by display (4)
Coordinate is simultaneously operated.Centre has been related to the technologies such as data communication and numerical map, therefore it is outer to also need to serial ports, memory etc.
Enclose hardware device (2).
In fig. 2, to have chosen Linux vehicle-mounted to develop to do the operating system (4) and Qt/E of onboard navigation system for the present invention
The GUI (2) of navigation system, wherein (SuSE) Linux OS (4) are altogether by linux kernel (5), file system (3) and Qt/E
Man-machine interface (2) etc. is constituted.Additionally, the start-up course of Linux also needs to Bootloader bootstrap (6) to load it
To the operation of internal memory.This software systems is built upon with based on hardware platforms (7) of the ARM as core.
Claims (2)
1. the GPS onboard navigation systems of ARM are based on, with embedded ARM processor as core, with open source linux as operating system, communicated with hardware platform using GPS module, and interface development is carried out by last Qt/E, to be designed to onboard navigation system, it is characterized in that：(1) hardware platform of onboard navigation system is built as core with S3C2440A microprocessors, including the design of the main peripheral module of onboard navigation system, onboard navigation system is mainly made up of message processing module, gps signal acquisition module and human-computer interaction module etc., and each peripheral module includes power supply, display, memory, serial ports etc.；(2) Software for Design platform is built for onboard navigation system, is included in foundation of the foundation of embedded Linux system development environment, cross compilation environment etc. on host, the transplanting of linux system is mainly on target machine；(3) application program of onboard navigation system is have developed under (SuSE) Linux OS environment, including the collection of gps signal is developed with process, with Qt/E to interface, and realize the function of onboard navigation system.
2. GPS onboard navigation systems based on ARM according to claim 1, it is characterised in that：(1) hardware components：GPS navigation system first has to receive satellite-signal by gps receiver, then parse corresponding position data using ARM microprocessor and carry out data processing, show current coordinate and operated in electronic chart by display, centre has been related to the technologies such as data communication and numerical map, therefore also needs to the peripheral hardware devices such as serial ports, memory；(2) software section：The GUI for choosing Linux to do the operating system and Qt/E of onboard navigation system to develop onboard navigation system, wherein (SuSE) Linux OS is made up of altogether linux kernel, file system and Qt/E man-machine interfaces etc.；Additionally, the start-up course of Linux also needs to Bootloader bootstrap to load the operation that it arrives internal memory, and software systems are built upon with based on hardware platforms of the ARM as core.
