At present, in the wireless dispatching command transfer mode that railway adopted at home, what the dispatching command wireless data transmission channel between the car ground adopted is these several kinds of modes of 400MHz, 800MHz, 400KHz radio communicating channel and GSM-R transmission channel.Wherein, Former three belongs to the radio communication mode; Because the restriction of communication distance and bandwidth chahnel; Be mainly used in the station with interval in the voice communication and the small character segment data of train communicate by letter, that can't carry out each locomotive in service on each station, control room and the circuit contacts directly the wireless transmission requirement of incompatible all fronts road dispatching command; GSM-R then is the exclusive GSM channel resource of the Ministry of Railways, has the fast characteristics of base station access speed, but owing to exist infrastructure (need set up mass communication equipment and base station along the line) first stage of construction input cost high; Construction period is long; Because equipment and base station mostly are arranged on interpersonal rare locations extremely such as tunnel, mountain area, and operation expense is also high, the troubleshooting cycle is long simultaneously; Therefore at present only at home newly-built high ferro circuit and Qinghai-Tibet Railway, Qun Dynasty's line adopts to some extent; Simultaneously, GSM-R is because the restriction of its bandwidth, also is difficult to comprise the transmission of the high amount of traffic of view data.
The utility model content
The utility model provides a kind of railway dispatching command transfer system that can overcome above-mentioned defective to the limitation and the defectives such as the GSM-R maintenance cost is high, troubleshooting cycle length of radio communication in the prior art on communication distance and bandwidth chahnel.
The utility model provides a kind of railway dispatching command transfer system, and this system comprises car-mounted terminal, the communication server and data processing server, wherein:
Said data processing server is used to work out dispatching command and the dispatching command of working out is sent to the said communication server;
The said communication server is used for through GPRS or 3G cordless communication network the dispatching command of said establishment being sent to said car-mounted terminal;
Said car-mounted terminal then is used for will sending to the said communication server to the response of the dispatching command of said establishment through said GPRS or 3G cordless communication network; And
The said communication server also is used for the response that receives from said car-mounted terminal is sent to said data processing server.
Since according to the car-mounted terminal of the utility model and the communication server through utilizing existing maturation and public wireless communication network wide coverage is that GPRS and 3G cordless communication network communicate; So can need not to lay the real-time Transmission that realizes dispatching command under the situation of expensive dedicated communication equipment, base station, thereby overcome the limitation of radio communication on communication distance and bandwidth chahnel and the defective that the GSM-R maintenance cost is high, the troubleshooting cycle is long in the prior art.In addition, because the utility model can need not controlled the transmission that realizes dispatching command under the situation of shutting down car, thus also reduced train stop frequency and time greatly, thus the circuit traffic density increased greatly, improved prouctiveness.
