Abstract
The invention discloses an efficient vehicle-mounted terminal, which comprises a central processing unit, a Beidou positioning module, a display screen, RS232 interfaces and a speed sensor. The Beidou positioning module, the display screen, the RS232 interfaces and the speed sensor are all connected with the central processing unit, the central processing unit is also connected with an FM (frequency modulation) transmitter module and an SDRAM (synchronous dynamic random access memory) and/or a FLASH, and the Beidou positioning module is also connected with a positioning antenna. According to the principle, the vehicle-mounted terminal has a communication function, short message service and navigation are combined, quick positioning is realized, and communication blind zones are reduced.
Description
Technical field
The present invention relates to the car-mounted terminal field, be specifically related to the high-level efficiency car-mounted terminal.
Background technology
Car-mounted terminal is of many uses, can realize integrated positioning, the multiple functions such as communication, automobile travel recorder.It has powerful professional scheduling feature and data-handling capacity, this calling of supporting telephone, Word message voice broadcast and vehicle scheduling monitoring terminal (TCU terminal).In addition, also have security alarm, trimming warning and telesecurity oil-break, outage safety protection function.Car-mounted terminal is reserved a plurality of RS-232 interface and RS485 interface, can external fee register, camera, microphone, earphone, TTS phonetic synthesis box.The split-type design main frame can hiddenly be installed, provide for oneself a large amount reserve battery can for car-mounted terminal without the warning of working in the electric situation.Car-mounted terminal is the front-end equipment of vehicle monitoring management system, generally is installed in reconditely in the various vehicles.The car-mounted terminal that uses does not now have communication function, can not realize the combination of short message service and navigation, and contrast locating is slower, also has communication blind district.For large-range monitoring and the management of car-mounted terminal, and without relying on the application of area data collection user data transmission just to seem extremely inconvenient.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, and the high-level efficiency car-mounted terminal is provided, and car-mounted terminal has communication function, realizes the combination of short message service and navigation, realizes fast location, has reduced communication blind district.
For solving above-mentioned technical matters, the present invention is by the following technical solutions: the high-level efficiency car-mounted terminal, comprise central processing unit, Big Dipper locating module, display screen, RS232 interface and speed pickup, described Big Dipper locating module, display screen, RS232 interface and speed pickup all are connected with central processing unit; Described central processing unit also connects FM transmitter module and SDRAM AND/OR FLASH; Described Big Dipper locating module also connects positioning antenna.
Further, described display screen is the LCD LCDs.
Further, described RS232 interface is provided with a plurality of.
Further, the model of described Big Dipper locating module is TD3017.
Further, the model of described central processing unit is arm cortex3739.
Further, the model of described FM transmitter module is SX750.
Compared with prior art, the invention has the beneficial effects as follows:
1, the present invention has increased communication function, realized the combination of short message service and navigation feature, can realize round-the-clock quick location, in the situation that guarantee that bearing accuracy contains few communication blind district, and can realize the compatibility with GPS, be very suitable for large-range monitoring and the management of car-mounted terminal.
2, the display screen of the present invention's employing is LCD display, can adjust the screen height according to desirable visibility, and image quality is clear, and is stable, uses to such an extent that eyes can be comfortable too for a long time, and the picture that demonstrates is better.
3, highly sensitive, the stable high and low debugging of making an uproar, exempt from of the transmitter module of the present invention's employing, outward element is few, uses extremely simple.Need not to add in addition the PA circuit, transmitting range is far away again.Adopt PLL phase-locked loop frequency stabilization technology, transmission frequency is stable, and antijamming capability is strong.
Description of drawings
Fig. 1 is theory diagram of the present invention.
Embodiment
The present invention is further elaborated below in conjunction with accompanying drawing, and embodiments of the invention are not limited to this.
Embodiment:
As shown in Figure 1, the present invention includes central processing unit, Big Dipper locating module, display screen, RS232 interface and speed pickup, RS232 interface wherein is set to a plurality of.Described Big Dipper locating module, display screen, RS232 interface and speed pickup all are connected with central processing unit, and display screen is the LCD LCDs.Central processing unit of the present invention also connects FM transmitter module and SDRAM AND/OR FLASH; Described Big Dipper locating module also connects positioning antenna.The model of Big Dipper locating module of the present invention is TD3017, and the model of central processing unit is arm cortex3739, and the model of FM transmitter module is SX750.SDRAM AND/OR FLASH wherein is at least one in dynamic RAM and the Data Buffer Memory.
Big Dipper locating module is connected with positioning antenna, is used for receiving the location and realizes the short message communication function.Speed pickup is then for detection of car speed, and then the short-term service by Big Dipper locating module sends and the combination of navigating, and reduces communication blind district, realizes the quick location of vehicle, realizes that the large-range monitoring of vehicle is in management.The FM transmitter module is listened to music by transmitting signals to car audio system.
Just can realize this invention as mentioned above.
