Description of drawings
Fig. 1 is the structure chart of the airborne station system that provides of the utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
The structure of the airborne station system that the utility model provides for convenience of explanation, only shows the part relevant with the utility model as shown in the frame of Fig. 1, these parts can be the unit of hardware or software and hardware combining.
As shown in the figure, described airborne station system is made up of two transceivers and two control boxes, and each control box all can independently be controlled the operating state of arbitrary transceiver.
Control box A12, control box B16 are installed in respectively in the different driving cabin (front deck, rear deck) as independent assembly.The driver can by corresponding switch, knob and button on the control box realize to the noise elimination of transceiver A11/ transceiver B15 select, the lifesaving channel is opened and function operations such as frequency inverted.Simultaneously, demonstration on the control box and indicating section also can provide correspondent frequency, channel shows and the indication of function.When same transceiver of control, by the method for synchronization information of controlled transceiver is presented on the another one control box, realize information transparency and shared; When controlling different transceivers, operation separately is independent of each other, and can control local volume independently, and is interference-free.
Power/audio module, receiver module, frequently comprehensive module, modulation module and power amplifier module have been included among transceiver A11 and the transceiver B15, can realize air to air reaching air-to-ground half-duplex operation, also adopt software radio and DSP signal processing technology to realize reaching synchronously fast the flexibility of other high performance index and function increase and decrease simultaneously.
Under the accepting state, transceiver A11 and transceiver B15 carry out demodulation process to the external signal that the antenna by separately receives respectively.The audio signal that each transceiver demodulates is sent to control box A12 and control box B16 simultaneously, the driver can regulate the audio frequency output amplitude of transceiver A11/ transceiver B15 in this locality respectively by two volume potentiometers on the control box in cabin, place, audio signal output behind the ECDC road is to the interphone of local (being the cabin, place), be sent to local headset by local interphone again, so each driver can hear the audio signal from two transceivers, and can independently adjust local volume.
Under the transmit status, the microphone on headset A14, the headset B17 is sent to interphone A13, interphone B17 respectively with driver's audio signal.The driver can select arbitrary transceiver to send audio signal by the respective keys on the control box in cabin, place, control box then sends to this control information the selected transceiver of driver, this transceiver is then connected selected interphone, and receive the driver's of this interphone output audio signal, sample, go out by antenna transmission processing such as modulation back, simultaneously, this transceiver is also handled this audio signal, and pass out in two drivers' the earphone in the mode of sidetone, so when a driver externally conversed, the driver in another cabin can hear his conversation.
Current, when the rear deck driver controls same transceiver by control box separately, because the synchronization transceiver can only be accepted a driver's control, transceiver will be arranged the control command that receives according to processing earlier first, the crowded mode of moving back the first person that has come of late comer, and the control command that receives with final time is the final operating state of transceiver.When two drivers controlled same transceiver simultaneously and launch, this transceiver only thought that control command that the control box in coach cabin, place (generally being rear deck) sends effectively and handle.
When the driver externally launches conversation signal by certain transceiver, in order not influence driver's normal talking quality, control box inside will cut off before entering volume control knob from the audio signal of another transceiver automatically.
Above-mentioned two control boxes can be controlled any one transceiver separately, also can two control boxes be controlled by same transceiver.Any one control box can show the transceiver that the other side's control box is controlled and the frequency range of work thereof.Also be provided with synchro light on each control box, when two control boxes are controlled same transceiver, promptly think synchronous regime, synchro light is bright.For fear of two control boxes under same channel number that parameter is set is inconsistent, cause the difference of control and show state, control box also possesses the function of carrying out mutual school of parameter and parameter synchronization when powering on, prompting driver selection reference control box when verification is inconsistent, and according to selecting to carry out parameter synchronization.
In addition, described control box is also supported the stores synchronized that channel parameter is provided with, and when revising and storing the channel parameter of a control box, simultaneously the parameter of another control box is carried out stores synchronized.
Above-mentioned two transceivers can not be operated on the same frequency simultaneously.
