Background technology

At present, because a large amount of application of electronic technology is in mobile unit, vehicle electric field has become very important part in the whole automotive field.In the existing vehicle electronics, common equipment comprises GPS navigation, GPS scheduling, Tachographs, car phone, vehicle-mounted radio, car door/reversing image monitoring, vehicle-mounted video recording, voice station reporting instrument etc.Yet these equipment all are independently basically, mutually between not contact, do not become system, every kind of equipment all develops in the technical field of oneself.

In order to adapt to the regulatory requirement of present vehicle, some vehicles have almost been installed above-mentioned all devices.Such as managing on the strict relatively public transit vehicle, a large amount of electronic machines just has been installed.Because self not contact between these equipment, each all has oneself read-out, shell, fixed form, power module etc., and this just brings many new problems for these vehicles.Be in particular in:

1) interior space is narrow and small, that these equipment are very crowded fully, disturbs between mutually to strengthen, and stability reduces.

2) every kind of equipment all has independently read-out, causes chaufeur to be taken sb's mind off sth easily, increases accident rate.

3) every kind of equipment all has independently power supply, and the efficient of power supply is limited, and all devices power consumption of adding up increases, and reduces the service life of automobile storage battery.

4) various device is unfavorable for facility management from different manufacturers, and is difficult in maintenance, and maintenance cost rises.

5) various device has the parts (as power supply) that many mutual functions repeat, and purchase cost rises, serious waste of resources.

6) function of every kind of equipment is met fixingly, does not have upgrading space, increases new management function if desired, needs to purchase new equipment again.

7) various device does not all have bus architecture, can not effectively connect with the intrinsic electronic machine of automobile (as electronic instrument), and the operational factor of vehicle can not effective monitoring.

The specific embodiment

In order to solve in the prior art, vehicle electronics is of a great variety, function singleness, installation complexity, problem that operating efficiency is low, and the utility model utilizes embedded type CPU to construct open multifunctional information platform, and all devices is combined, form complete system, its structure is as follows:

Adopt ARM11 as embedded type CPU, promptly the ARM11 microprocessor moves LINUX operating system, and a plurality of functional modules are carried out multitask, multi-process, management simultaneously; Wherein, a plurality of functional modules comprise: GPS module, GPRS/3G module, radio receiver module, sound card power amplifier module, AV signal output module, LCD display, USB driver module, keyboard, SD card module, signal acquisition module, RS485 module, CAN bus module, image splitter; CPU is connected with each module communication respectively, and wherein, radio receiver module also communicates to connect with the sound card power amplifier module;

The basic function of each module is as follows:

1, the GPS module input is connected with gps antenna, receives location, the information of navigating, call out the stops of vehicle, shows by voice and LED and carries out automatic broadcasting;

2, GPRS/3G module input and GPRS/3G days wire joint receives conversation, wireless Internet access signal;

3, the radio receiver module input end is connected with radio aerial, receives radio receiver signal and signal is imported the sound card power amplifier module;

4, sound card power amplifier module and acoustic pickup, microphone, car inside trumpet communicate to connect, reception, transmission, processes voice signals;

5, the AV signal output module is connected with in-car TV, output TV AV signal;

6, LCD display shows image in real time;

7, the USB driver module connects USB flash disk/disk cartridge, the information that the SD card module stores can be outputed to USB flash disk/disk cartridge, also USB flash disk/disk cartridge can be imported the SD card module;
