Description
Technical field
The utility model relates to global position system technical field, relates to a kind of automobile GPS/ Beidou navigation repeater more specifically.
Background technology
GPS/ Big Dipper signal repeater is mainly used in compensating the power attenuation caused due to Signal transmissions and distribution in GPS/ Big Dipper indoor distributed system.Existing signal repeater only has radio frequency amplifying unit usually, and its shortcoming is that equipment gain is fixed, and cannot make corresponding gain-adjusted according to on-site signal situation and show gain-adjusted numerical value.
Summary of the invention
The one that the purpose of this utility model is exactly deficiency in order to solve prior art and provides is installed simple, easy to use, can according to the signal repeater of the global position system of practical service environment conditioning equipment gain.
The utility model adopts following technical solution to realize above-mentioned purpose: a kind of signal repeater of global position system, comprise the power supply of housing and interior setting thereof, power splitter, radio-frequency module, radio-frequency module is connected to the output of power splitter, it is characterized in that, it also comprises MCU control module, input through keyboard module and display module, the gain of MCU connection control radio circuit, and output display is on display module.
Further illustrating as such scheme, the output of described MCU control module is provided with display screen interface, and display module adopts liquid crystal display screen, is connected with display screen interface.
The input of described MCU control module is provided with keyboard interface, input through keyboard module adopts and touches keyboard, touching keyboard is connected on keyboard interface, by the gain of input through keyboard gain-adjusted radio circuit, reach and according to the gain of practical service environment conditioning equipment, the signal strength signal intensity that indoor signal reaches best can be made.
Described liquid crystal display screen is positioned at the end face of housing, touches the outside that keyboard is fixed on liquid crystal display screen.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model have employed the gain of MCU centralized control radio-frequency module, and output to display module display, reach and according to the gain of practical service environment conditioning equipment, the signal strength signal intensity that indoor signal reaches best can be made, and be presented at LCD screen intuitively, improve user's experience.

Embodiment
Below in conjunction with specific embodiment, the technical program is explained in detail.
As shown in Figure 1-Figure 3, the utility model is a kind of signal repeater of global position system, comprise the power supply 2 of housing 1 and interior setting thereof, power splitter 3, radio-frequency module 4, MCU control module 5, input through keyboard module 6 and display module 7, radio-frequency module is connected to the output of power splitter, the gain of MCU connection control radio circuit, and output display is on display module.The output of MCU control module is provided with display screen interface 8, and display module adopts liquid crystal display screen, is connected with display screen interface.The input of MCU control module is provided with keyboard interface 9, input through keyboard module adopts and touches keyboard, touching keyboard is connected on keyboard interface, by the gain of input through keyboard gain-adjusted radio circuit, reach and according to the gain of practical service environment conditioning equipment, the signal strength signal intensity that indoor signal reaches best can be made.Wherein, liquid crystal display screen is positioned at the end face of housing, touches the outside that keyboard is fixed on liquid crystal display screen.
The utility model is compared with existing GPS/ Big Dipper signal repeater, its technological improvement point is: have employed MCU control module centralized control, by the gain of input through keyboard gain-adjusted radio circuit, and output to liquid crystal display screen display, reaching can according to the gain of practical service environment conditioning equipment, make the signal strength signal intensity that indoor signal reaches best, and be presented at LCD screen intuitively, improve user's experience.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
