Abstract
The utility model discloses a digital multimedia broadcast receiver with a global positioning system providing a digital multimedia broadcast receiver with functions of global position and reception of the ground broadcasting in large covering scope. The utility model comprises a digital multimedia broadcast transmitting / receiving module connected with a MPU / DSP dual core processor which is joined with a GPS receiving module, a keyboard control module connected with a keyboard, a display control module connected with a displayer, an external program memory, an external data memory and a high frequency and constant temperature oscillator respectively. The utility model is capable of receiving the ground broadcasting signal, the satellite broadcasting signal and, at the same time, the signal transmitted from the navigation satellite to obtain the necessary navigation and position information and complete navigation and position work through data processing which can survey the geographic location of the DMB receiver at any time.
Description
Technical field
The utility model relates to the DMB field, in particular, relates to a kind of digital multimedia broadcast receiver with global positioning system.
Background technology
Audio signal and various data service signal that DMB (DMB) has been meant digitlization carry out processing such as various codings, modulation, transmission under digital state.DMB owing to have tonequality good, can realize that multimedia receives that but high-speed mobile receives, can encrypt, transmitting power is little, area coverage is big, the availability of frequency spectrum is high, have very strong ability anti-interference and that receive to be subjected to people's favor under adverse circumstances.But existing DMB receiver can not be realized global positioning function, can not survey the geographical position at DMB receiver place at any time, has certain limitation.
The utility model content
The utility model is in order to overcome weak point of the prior art, a kind of digital multimedia broadcast receiver with global location and large coverage reception terrestrial broadcasting function to be provided.
The utility model is achieved through the following technical solutions:
A kind of digital multimedia broadcast receiver with global positioning system, comprise the DMB transmit/receive module, it is characterized in that, described DMB transmit/receive module is connected with the MPU/DSP dual core processor, described MPU/DSP dual core processor is connected with GPS receiver module, Keyboard Control module, display control module, external program memory, external data memory, high frequency constant temperature oscillator respectively, described display control module is connected with display, and described Keyboard Control module is connected with keyboard.
The utlity model has following technique effect:
The utility model can be when receiving ground broadcast signal (T-DMB) and satellite broadcast signal (S-DMB), also receive the signal of navigation satellite emission, thereby obtain necessary navigation and locating information, through data processing, finish navigation and location work, can survey the geographical position at DMB receiver place at any time.
Description of drawings
Fig. 1 is the internal circuit schematic diagram with digital multimedia broadcast receiver of global positioning system.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
Fig. 1 is the schematic diagram that the utlity model has the digital multimedia broadcast receiver of global positioning system, comprise the DMB transmit/receive module, the DMB transmit/receive module is connected with the MPU/DSP dual core processor, described MPU/DSP dual core processor is connected with GPS receiver module, Keyboard Control module, display control module, external program memory, external data memory, high frequency constant temperature oscillator respectively, described display control module is connected with display, and described Keyboard Control module is connected with keyboard.
This system adopts the bus multiplex mode to realize function, select the FLASH module as external program memory, SRAM is an external data memory, and the Keyboard Control module is as the Keyboard Control signal, and the high frequency constant temperature oscillator is a MPU/DSP dual core processor transmit clock signal.The keyboard input module is the function button on the DMB receiver.DMB receives and the emission broadcast singal, GPS carries out signal exploration and data acquisition, the satellite-signal that GPS receives is transferred to the MPU/DSP dual core processor by data/address bus, DSP part is wherein carried out coding and decoding to the signal that is received, calculate the particular location of DMB receiver, and show by display control module control display.
Although relate to a kind of digital multimedia broadcast receiver and carried out special description disclosed with global positioning system with reference to embodiment, embodiment described above is illustrative and not restrictive, under the situation that does not break away from spirit and scope of the present utility model, all variations and modification are all within scope of the present utility model.
