Abstract
The invention relates to the field of radio and particularly relates to a radio and a method for selecting two antennae or one single antenna. The radio comprises a chip, two antennae and two radio signal input ends. The two antennae comprise a first antenna and a second antenna, the two radio signal input ends comprise a first radio signal input end and a second radio signal input end. The first radio signal input end is connected with the first antenna and the second antenna, the second radio signal input end is connected with the first antenna, and a switch is arranged between the first radio signal input end and the second antenna. By the aid of the method, users can have more selection, the background can scan the whole frequency band automatically in case of the two antennae, and accordingly, users do not need to scan the whole frequency again, the background switching speed is fast, and two Tuners can share one antenna when the single antenna is selected.
Description
Technical field
The present invention relates to broadcast receiver field, particularly relate to a kind of method of broadcast receiver and realization selection double antenna or single antenna.
Background technology
Broadcast receiver product of usually seeing of right and wrong in onboard system.But present most broadcast receiver is single antenna.The present invention is that the broadcast receiver on vehicle-mounted can select single antenna or double antenna.First the broadcast receiver of band selection antenna must be the broadcast receiver of double T uner, is putting before this, and select single antenna to search for, cost is lower, and on loading easily; If selecting is that double antenna is searched for, the anti-interference row of radio reception can be strengthened, and double T uner can be allowed separately to work: a Tuner carries out the broadcasting in radio station, and another Tuner can carry out the scanning on backstage, such efficiency is just higher, does not need each all full frequency bands search.Must be just double antenna or single antenna surely time in production, such user just can not revise.
Summary of the invention
In view of above-mentioned the deficiencies in the prior art part, a kind of broadcast receiver and realization is the object of the present invention is to provide to select the method for double antenna or single antenna.
In order to achieve the above object, this invention takes following technical scheme: described broadcast receiver comprises chip, antenna and reception signals input, described antenna is two, first antenna and the second antenna, described reception signals input is two, first reception signals input and the second reception signals input, described first reception signals input connects the first antenna and the second antenna, described second reception signals input connects the first antenna, is provided with switch between described first reception signals input and described second antenna.
Be improved to further the present invention: described broadcast receiver is provided with two chips, be respectively stm32 chip and 726b chip, described stm32 chip connects described 726b chip, and described 726 chips connect described switch.
Be improved to further the present invention: described broadcast receiver is provided with a button C, button connects chip stm32, and stm32 chip connects 726b chip.
It is a kind of based on above-mentioned feature wireless one realization selection double antenna or the wireless method of single antenna,
A presses C key, enters choice for use single antenna or double antenna pattern;
B stm32 chip senses key command, shows single double antenna options, user's choice for use single antenna or double antenna;
C stm32 chip senses key command, and stm32 chip passes to 726b chip by serial agency;
D 726b chip calls event interface, if selection single antenna, 726b chip controls switch opens, make the first reception signals input work, close the second reception signals input, if select double antenna, 726b chip controls switch closes, first reception signals input and the second reception signals input are worked simultaneously, and the second antenna and the first reception signals input disconnect;
E realization event, returns to stm32 chip by return value;
F stm32 shows the data received, and completes single double antenna and selects.
Be improved to further the present invention: when user does not select single double antenna, broadcast receiver acquiescence uses single antenna broadcast receiver.
Compared to prior art, method provided by the invention, make mainly to make the selection of user more in this way, when double antenna, the whole frequency range of backstage meeting automatic scan, such user does not just need again to scan whole frequency, and the speed of handoff radio also can accelerate, select single antenna, namely double T uner shares an antenna.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention;
Fig. 2 is inventive antenna overall structure figure;
Fig. 3 is that the present invention selects single double antenna flow chart.
Embodiment
The invention provides a kind of method of broadcast receiver and realization selection double antenna or single antenna, for making object of the present invention, technical scheme and effect clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
A kind of broadcast receiver of the present invention, comprise described broadcast receiver and comprise chip, antenna and reception signals input, described broadcast receiver is provided with two antennas, the first antenna and the second antenna, and described reception signals input is two, first reception signals input and the second reception signals input, described first reception signals input connects the first antenna and the second antenna, and described second reception signals input connects the first antenna, and described first reception signals input and described second antenna are provided with switch.Described broadcast receiver is provided with two chips, is respectively stm32 chip and 726b chip.Described broadcast receiver is provided with a button C, and button connects chip stm32, and stm32 chip connects 726b chip.Two chips, stm32 mainly completes the work of display information; 726b chip mainly completes function, then the data obtained is sent to stm32, allows stm32 go display.After completing display, user can see the options being shown single double antenna by stm32 chip, and user selects double antenna or single antenna by the selection of button.Show after information completes and have selected at stm32, pass to 726b chip by press key message and go to perform the algorithm between antenna, determine double antenna or single antenna.
It is a kind of based on above-mentioned feature wireless one realization selection double antenna or the wireless method of single antenna,
A presses C key, enters choice for use single antenna or double antenna pattern;
B stm32 chip senses key command, shows single double antenna options, user's choice for use single antenna or double antenna;
C stm32 chip senses key command, and stm32 chip passes to 726b chip by serial agency;
D 726b chip calls event interface, if selection single antenna, 726b chip controls switch opens, make the first reception signals input work, close the second reception signals input, if select double antenna, 726b chip controls switch closes, first reception signals input and the second reception signals input are worked simultaneously, and the second antenna and the first reception signals input disconnect;
E realization event, returns to stm32 chip by return value;
