Description
Technical field
The utility model relates to railway communication technical field, particularly a kind of reconnection communication transposer station, is exclusively used in heavy haul train reconnection communication system of growing up.
Background technology
Shaoshan series cab traction of the former use direct current of current most heavy haul train, uses 400MHz+400KHz to combine radio station.During existing 400MHz radio station reconnection communication, adopt between master control locomotive and slave controller car driver and carry out voice communication with frequently straight-through intercommunication mode, frequency fn(459.0-461.5MHz, fn associate with the engine number of locomotive equipment) intercommunication mode carries out voice communication.
The 400KHz radio station that 400MHz+400KHz combines in radio station couples a signal to contact line by antenna, and is passed to slave controller car, not by topography and geomorphology and distance limit, therefore in tunnel, cutting, bend and long interval section mainly use 400KHz radio station.And 400MHz radio station utilizes space wave to propagate, affect huge by tunnel, cutting, bend etc.;
According to production and transport and traction marshalling needs, after introducing alternating current large-power locomotive, affect by AC great current, 400KHz radio station is substantially in paralyzed state, cannot use; And 400MHz radio station affects by topography and geomorphology, communication success rate and quality low, also cannot meet the demand of ten thousand tons of unit car reconnection communications.How to address this problem the problem just becoming those skilled in the art and will study and solve.
Summary of the invention
The purpose of this utility model is exactly for overcoming the deficiencies in the prior art, for an above-mentioned difficult problem, provide a kind of structural design scheme of reconnection communication transposer station, by the circuit structure adopting simulation, numeral combines, improve communication reliability, meet the demand communicated in complex situations.
For achieving the above object, the utility model is realized by such technical scheme: a kind of reconnection communication transposer station, comprise transmitter, receiver, duplexer and CPU, also comprise codec chip, voicefrequency circuit, receiver output connects codec chip, codec chip connects transmitter input, and voicefrequency circuit is connected between receiver output and transmitter input, the circuit structure that formation simulation, numeral combine.
The beneficial effects of the utility model are: by the circuit structure adopting simulation, numeral combines, improve communication reliability, meet the demand communicated in complex situations, are applicable to very much current heavy haul train reconnection communication system of growing up and use.
Accompanying drawing explanation
The theory diagram in Fig. 1, the utility model radio station.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
The theory diagram in radio station as shown in Figure 1.A kind of reconnection communication transposer station, comprise transmitter, receiver, duplexer and CPU, also comprise codec chip, voicefrequency circuit, receiver output connects codec chip, codec chip connects transmitter input, and voicefrequency circuit is connected between receiver output and transmitter input.
Whether when radio station receives radiofrequency signal from antenna feeder termination, first detecting is that receive frequency is preset in radio station, if start digital signalling decoding function immediately.The codec chip that the utility model uses is the integrated digital signal processing chip of a height.If (such as engine number tail number is the train of 01 to comprise digital Gray code legal in system in the signal received, corresponding Gray code is 023), voicefrequency circuit is opened immediately, the continuous infrasonic frequency signaling of 107.2Hz, 156.7Hz is added in voicefrequency circuit by codec chip, and the signal like this with analogue signalling is launched by transmitter.
In practical application scene, reconnection communication requires to communicate between the master control locomotive of same train number and slave controller car, and the reconnection communication of other train numbers can not be disturbed, therefore use digital signalling and running number one_to_one corresponding, just can make can not interfere with each other between the locomotive of different train number; Recycling analogue signalling forward signal, further increases the reliability of reconnection communication, thus makes reconnection communication not be subject to the impact of topography and geomorphology or other complex situations.
According to the above description, scheme of the present utility model can be realized in conjunction with art technology.
