Abstract
The utility model, which relate to the positioning navigation field, particularly discloses a Beidou module with inertial navigation. The Beidou module is composed of a core module, a power supply management unit integrated at the core module, a radio frequency circuit, an acceleration sensor, and a battery unit, wherein the radio frequency circuit, the acceleration sensor, and the battery unit are respectively connected with the core module. According to the scheme, the provided Beidou module has the following advantages: because the core module is integrated with the power supply management unit, there is no need for the whole module to be provided with a power supply circuit additionally and power supplying of the whole module can be realized only by one dry battery, thereby simplifying the power supply circuit. Moreover, the Beidou module has the simple structure and the small size; and the module also has the positioning function of the acceleration sensor and thus the GPS/beidou dual-mode function and the power consumption is low.
Description
Technical field
The utility model relates to positioning and navigation field, refers to especially a kind of Big Dipper module with inertial navigation.
Background technology
At present, navigational system from military gradually to civilian excessively, big-dipper satellite has brought facility to the development of navigation to civilian opening, in numerous products, majority all cannot meet supports that the cost of GPS and the double mode navigation feature of the Big Dipper and system is high simultaneously, and power consumption is large, module integration degree is low, volume is large, and peripheral circuit complexity is difficult for realizing.
Therefore, on market, need to invent a kind ofly utilize the module of high integration to there is low-power consumption to realize, volume is little, the Big Dipper module of compatible with GPS and the double mode location navigation of the Big Dipper.
Utility model content
The purpose of this utility model is to provide a kind of GPS/ Big Dipper bimodulus satellite positioning module, and the integrated level of module is high, and peripheral circuit is simple, low in energy consumption, and volume is little.
To achieve these goals, the utility model has adopted following technical scheme: a kind of Big Dipper module with inertial navigation, the radio circuit, acceleration transducer and the battery unit that comprise nucleus module, be integrated in Power Management Unit on nucleus module, be connected with nucleus module respectively.
Further, described nucleus module is provided with STA8089 chip.
Further, described nucleus module is provided with LNA-RFA circuit.
Further, described nucleus module is connected by radio frequency analog signal line with radio circuit.
Further, described nucleus module is connected by I2C bus with acceleration transducer.
The beneficial effects of the utility model are: due to integrated Power Management Unit on nucleus module, therefore whole module does not need additional power source circuit, only need can realize the power supply to whole module once joint dry cell, have simplified power circuit.This Big Dipper modular circuit is simple, and volume is little, simultaneously with accelerator sensor positioning function, has realized GPS/ Big Dipper dual mode capability, and power consumption is little.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment technical scheme, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only that this practicality is in order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is module principle figure of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of Big Dipper module with inertial navigation as shown in Figure 1, the radio circuit 4, acceleration transducer 3 and the battery unit 5 that comprise nucleus module 1, be integrated in Power Management Unit 2 on nucleus module 1, be connected with nucleus module 1 respectively, described nucleus module 1 is connected by I2C bus with acceleration transducer 3, and described nucleus module 1 is connected by radio frequency analog signal line with radio circuit 4.Accelerator sensor receives data like this, feeds back to nucleus module 1.Nucleus module 1, with accelerator sensor positioning function, has been realized GPS/ Big Dipper dual mode capability simultaneously, and power consumption is little.Integrated Power Management Unit 2 on nucleus module 1, therefore whole module does not need to add power circuit, only needs can realize the power supply to whole module once joint dry cell, has simplified power circuit.
Wherein, described nucleus module 1 is provided with STA8089 chip; Make the circuit of whole module simple, volume is little.
Wherein, described nucleus module 1 is provided with LNA-RFA circuit; Integrated LNA-RFA circuit on nucleus module 1, therefore, the simple and easy realization of peripheral radio circuit 4 of module, on nucleus module 1, also integrated inner crystal oscillator, so peripheral circuit does not need external crystal-controlled oscillation, has simplified circuit and has increased again stability.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
