Description
?
Technical field
The present invention relates to railway communication equipment, relate in particular to a kind of railway responder system.
Background technology
The railway responder system is the big capacity information transmission system of the point type of a safety.Adopt digital coding, can realize the transfer of data between ground and the train, after handling, obtain corresponding information, submit to car-mounted computer, be used for overspeed protection or Train Positioning etc.
At present, the railway responder system is still blank in the application of China, and the ground that present Chinese Railway is mainly used and the mode of intelligence transmission of train are continuous track circuits.Present prevailing non-insulated track circuit has French UM7l, homemade WG-2lA and ZPW-2000A etc.; They all can obtain continuous information; But amount of information wretched insufficiency; The low frequency information kind is merely 18 kinds, can not provide speed-limiting messages for speed limit points such as ramp, bend, track switch, bridges, can not satisfy the needs of high-speed cruising.
So, just need a kind of railway responder system to satisfy the current rail demands of applications.
Summary of the invention
The present invention is intended to propose a kind of railway responder system, and the bulky information transmission can be provided.
According to the present invention, a kind of railway responder system is proposed, comprising: on-vehicle parts and terrestrial components.On-vehicle parts is installed ON TRAINS, and on-vehicle parts comprises vehicle-mounted transponder antenna and vehicle-mounted transponder information receiving module, and vehicle-mounted transponder antenna can be connected with vehicle-mounted transponder information receiving module communicatedly.Terrestrial components is arranged along rail; Terrestrial components comprises the fixedly other electronic unit of message transponder, variable message transponder and rail; Wherein variable message transponder can be connected with the other electronic unit of rail communicatedly, and fixedly message transponder and variable message transponder and vehicle-mounted transponder antenna pass through wireless communication.
Fixedly message transponder and variable message transponder and vehicle-mounted transponder antenna communicate through radio frequency, use the anharmonicity feedback frequency.
Fixedly message transponder and variable message transponder comprise internal register, and internal register stores data with digital form.The train that on-vehicle parts is installed crosses the terrestrial components of arranging along rail; Vehicle-mounted transponder antenna is aimed at fixedly message transponder and variable message transponder, and vehicle-mounted transponder antenna is at first given fixedly message transponder and variable message transponder through way of electromagnetic induction with NE BY ENERGY TRANSFER with certain frequency; Start working after fixedly message transponder and variable message transponder receive energy delivered; The data that are stored in the internal register are modulated with frequency shift keyed mode; Be sent to vehicle-mounted transponder antenna through electromagnetic induction again; After vehicle-mounted transponder antenna receives modulated frequency shift keyed signals, send vehicle-mounted transponder information receiving module to and carry out demodulation, restore the data of storage.
Fixedly to use every frame length with variable message transponder and communicating by letter of vehicle-mounted transponder antenna be the message of 1023 bits to the message transponder, and wherein valid data length is 830 bits.
Adopt technical scheme of the present invention; This railway responder system has promoted the capacity of message transmission to a great extent; This railway responder system can satisfy the pinpoint requirement of train speed control system (especially moving block system) to train transmission such as signal message that signal demonstration, position coordinates, sweep, the gradient, speed limit condition etc. are relevant with operation.
Description of drawings
Fig. 1 has disclosed the structure chart of railway responder system of the present invention.
Embodiment
With reference to shown in Figure 1, the present invention has disclosed a kind of railway responder system, and this railway responder system comprises on-vehicle parts 10 and terrestrial components 20.
On-vehicle parts 10 is installed ON TRAINS, and on-vehicle parts 10 comprises vehicle-mounted transponder antenna 11 and vehicle-mounted transponder information receiving module 12, and vehicle-mounted transponder antenna 11 can be connected with vehicle-mounted transponder information receiving module 12 communicatedly.
Fixedly message transponder 21 comprises internal register with variable message transponder 22, and internal register stores data with digital form.
The working method of this railway responder system is following: the train that on-vehicle parts 10 is installed crosses the terrestrial components of arranging along rail 20.Vehicle-mounted transponder antenna 11 is aimed at fixing message transponder 21 and variable message transponder 22, and vehicle-mounted transponder antenna 11 is at first given fixedly message transponder 21 and variable message transponder 22 through way of electromagnetic induction with NE BY ENERGY TRANSFER with certain frequency.Fixedly message transponder 21 is started working after receiving energy delivered with variable message transponder 22, and the data that are stored in the internal register are modulated with the mode of frequency shift keying (FSK), is sent to vehicle-mounted transponder antenna 11 through electromagnetic induction again.After vehicle-mounted transponder antenna 11 receives modulated frequency shift keyed signals, send vehicle-mounted transponder information receiving module 12 to and carry out demodulation, restore the data of storage by vehicle-mounted transponder information receiving module 12.
In railway responder system of the present invention; Fixedly to use every frame length with variable message transponder 22 and communicating by letter of vehicle-mounted transponder antenna 11 be the message of 1023 bits to message transponder 21; Wherein valid data length is 830 bits, therefore the bulky information transmittability can be provided.
Adopt technical scheme of the present invention; This railway responder system has promoted the capacity of message transmission to a great extent; This railway responder system can satisfy the pinpoint requirement of train speed control system (especially moving block system) to train transmission such as signal message that signal demonstration, position coordinates, sweep, the gradient, speed limit condition etc. are relevant with operation.
