Description
Technical field
The present invention relates to communication technical field, particularly one is grown up heavy haul train reconnection communication system,
Be exclusively used in heavy haul train reconnection communication 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.In prior art, 400MHz radio station reconnection communication is applied between master control locomotive and slave controller car driver, and adopt and carry out voice communication with frequently leading directly to intercommunication mode, frequency is 459.0-461.5MHz.
400MHz+400KHz combines in radio station, and 400KHz radio station couples a signal to contact system by antenna, and is passed to slave controller car, by topography and geomorphology and distance restriction, therefore in tunnel, cutting, bend and long interval section mainly use 400KHz radio station.
400MHz radio station then utilizes space wave to propagate, and affects huge by tunnel, cutting, bend etc.; According to production and transport and traction marshalling needs, introduce 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 ratio and quality low, also cannot meet the demand of ten thousand tons of combined train 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
Object of the present invention is exactly for overcoming the deficiencies in the prior art, a kind of design plan of heavy haul train reconnection communication system of growing up is provided, in line with the object safeguarding national wealth safety and people's personal safety, the function of this reconnection communication system is mainly the reconnection communication demand of the heavy haul train that realizes growing up, and particularly also can ensure in tunnel and intersected country that communication is normally carried out.
The present invention is realized by such technical scheme: heavy haul train reconnection communication of growing up system, is characterized in that, system is primarily of multi-locomotive radio station, ground signal-relay station, webmaster exchange, access in radio equipment composition;
Heavy haul train of growing up is drawn by a master control locomotive and multiple slave controller car, every platform locomotive is all installed a multi-locomotive radio station, in tunnel, intersected country arranges some ground signal-relay station, ground signal-relay station is by connecting wired access device, pass through access in radio equipment again by Fiber connection to webmaster exchange, webmaster exchange is arranged on network management center;
The mode adopting alien frequencies to transfer the letter between multi-locomotive radio station communicates, and during communication, master control locomotive transmitting frequency Fa is to ground signal-relay station, and ground signal-relay station inversion frequency launches Fn, and slave controller car receives Fn; For preventing reconnection communication misconnection between different train number train locomotive from leading to, employing numeral, simulation mixing signaling ensure one_to_one corresponding between same train master control locomotive and slave controller car.
Beneficial effect:
Beneficial effect of the present invention is: by topography and geomorphology and distance restriction, do not affect, realize growing up the reconnection communication demand of heavy haul train by alternating current large-power locomotive big current, the success ratio that communicates and quality high, the demand of ten thousand tons of combined train reconnection communications can be met.

Fig. 1, overall system architecture block diagram.
Detailed description of the invention
For a more clear understanding of the present invention, the present invention is described in detail in conjunction with the accompanying drawings and embodiments:
Heavy haul train reconnection communication of growing up system, system is primarily of multi-locomotive radio station, ground signal-relay station, Network Management Equipment, access in radio equipment composition;
Heavy haul train of growing up is drawn by a master control locomotive and multiple slave controller car, every platform locomotive is all installed a multi-locomotive radio station, in tunnel, intersected country arranges some ground signal-relay station, ground signal-relay station is by connecting wired access device, pass through access in radio equipment again by Fiber connection to webmaster exchange, webmaster exchange is arranged on network management center.
The mode adopting alien frequencies to transfer the letter between multi-locomotive radio station communicates, and during communication, master control locomotive transmitting frequency Fa is to ground signal-relay station, and ground signal-relay station inversion frequency launches Fn, and slave controller car receives Fn; For preventing reconnection communication misconnection between different train number train locomotive from leading to, employing numeral, simulation mixing signaling technology ensure one_to_one corresponding between same train master control locomotive and slave controller car.
The communication means of heavy haul train reconnection communication system of growing up, comprising:
A) each forwarding point outfit two ground signal-relay stations, a ground signal-relay station is used for communicating with up locomotive station, and another portion is used for communicating with descending locomotive station; Access in radio equipment is responsible for connecting optical transmitter and receiver and ground signal-relay station, and webmaster exchange can to ground signal-relay station remote detection, remote inquiry parameter, long-range adjustment parameter; Operation system setting, ESC Escape have cryptoguard;
B) master control locomotive station presses assignment key, first sends call signaling, then sends communication signaling, is sent rear playing alert tones, enters communications status: now driver sends communication signaling by PTT with words, and on-hook is return and waited for;
C) after ground signal-relay station receives communication signaling, enter forwarding state immediately, determine that forwarding frequency Fn forwards, if receive call signaling in forwarding state, repeater station forwards communication signaling immediately, if can not receive communication signaling in continuous 9 seconds exit transfering the letter state;
D), after slave controller car radio station receives signaling call signaling, provide tunnel and heavily join key flash instruction, play the speech received, if under being now in stand-by state, off-hook can enter communication, sends communication signaling by PTT with words; As now carried out other communication, can listen to tunnel radio reconnection communication, as needs are answered, press tunnel and heavily join key and can communicate, other communication ongoing is hung up; Without continuing carrier wave in 9 seconds, tunnel heavily joins lamp and does not reresent.
According to the above description, the solution of the present invention can be realized in conjunction with art technology.
