The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1, a kind of vehicle track running control system based on the responser information transmission technology of the utility model comprises vehicle track running control convenience 1, responser information receiving module 2 and BTM Car antnna 3.The BTM Car antnna is installed in the rail vehicle car bottom, and the BTM Car antnna is lifted on the rail vehicle below by mounting bracket.

As shown in Figure 2, signal sending end mouth on the main frame of vehicle track running control convenience 1 is connected by employing standard RS422, RS485 serial interface or CAN communication modes 4 receiver port with responser information receiving module 2 main frames, receiver port on the main frame of vehicle track running control convenience is connected by employing standard RS422, RS485 serial interface or the CAN communication modes 4 signal sending end mouth with responser information receiving module main frame, and responser information receiving module main frame is connected with the BTM Car antnna by radio frequency cable 5.

A kind of vehicle track running control method based on the responser information transmission technology of the utility model may further comprise the steps:

Step 1: with vehicle track running control convenience main frame and the initialization of responser information receiving module main-machine communication, as shown in Figure 3,

Step 1:GYK prepares to communicate by letter with BTM foundation, sends the initialization information frame to BTM, and resetting receives waiting timer Tc, and judges whether Tc surpasses the time gap of setting, if not, continues to wait for; If so, GYK detects and has or not the status frames of receiving that BTM is correct, if nothing is returned step 1, continues to detect; If have, enter into step 2;

Step 2:GYK sends claim frame to BTM, resets to receive waiting timer Tc, and judges whether Tc surpasses the time gap that arranges, and if not, continues to wait for; If so, GYK detects and has or not the status frames of receiving that BTM is correct, if nothing is returned step 2, continues to detect; If have, enter into step 3;

Step 3: initialization is complete, and GYK and BTM begin mutual normal information;

Step 2: with responser information receiving module main frame and the initialization of vehicle track running control convenience main-machine communication, as shown in Figure 4,

Step is 1.: BTM prepares to set up with GYK and communicate by letter, and BTM detects and has or not the initialization information frame of receiving that GYK is correct, if 1. nothing returns step, if having, and replacement reception waiting timer Tc, and judge that 1. Tc whether in time slip-window, if not, returns step; If so, enter into step 2.,

Step is 2.: BTM detects and has or not the initialization information frame of receiving that GYK is for the second time correct, if 2. nothing returns step, continues to detect; If have, enter into step 3.,

Step is 3.: BTM sends correct status frames to GYK, and resetting receives waiting timer Tc, and judges that 1. Tc whether in time slip-window, if not, returns step; If so, BTM detects and has or not the status frames of receiving that GYK is correct, if 3. nothing returns step, continues to detect; If have, enter into step 4.,

Step is 4.: initialization is complete, and BTM and GYK begin mutual normal information;

Step 3: the BTM main frame passes through earthward responser transmission excitation energy electric wave of Car antnna, and receives the electric wave signal that ground transponder sends.BTM detects to have or not and receives responser information, if nothing is returned step 3, continues to detect; If have, enter into step 4;

Step 4: BTM detects and to receive responser information, generates corresponding control information data packet, to the GYK main frame data packet that sends control information, forwards step 5 to;

Step 5: GYK main frame receiving control information data packet, the data such as the transponder signal that the host software analysis receives, cab signal, speed signal are automatically calculated and are produced the control curve; At normal monitoring mode: when cab signal is L5, L4, L3, L2, L lamp, take the required basic specification of car controlling as foundation, take the outlet speed limit 80km/h of greenish-yellow lamp as target, generate target range control curve.By information and control curves such as DMI display speed, kilometer post, cab signal, circuit speed limits, remind the driver by the information that shows and the driving of control curve, forward step 6 to;

Step 6: receive responser absolute fix packets of information, GYK realizes kilometer post automatically to mark, revises rail vehicle kilometer post error; GYK moves control program, and when running into overspeed of vehicle or overrunning of signal, GYK sends corresponding brake command, implements braking by the brake equipment in the GYK peripheral interface, control car retardation or parking.

As shown in Figure 5, it is as follows that one of system applies example, GYK receive complete responser information and executing control flow:

Normal monitoring mode: when cab signal is L5, L4, L3, L2, L lamp, take the required basic specification of car controlling (track circuit information, responser information, rail vehicle parameter) as foundation, take the outlet speed limit 80km/h of greenish-yellow lamp as target, generate target range control curve.DMI is begun to successively decrease by target range apart from window display-object distance, is decremented to 0 rear demonstration "-----".

As shown in Figure 6, two of system applies example, it is as follows to carry out control flow when GYK reception responser information is damaged:

Damaged and so that GYK equipment can't be according to ceiling speed operation when transponder data, but track circuit is normal, and when TCR can correctly provide route opening state information, the GYK limited speed dropped to the running velocity 80km/h of both wired requirements automatically.When the responser track data can normally receive, GYK reentered (the prompting driver confirms, can raise speed after the affirmation) to the ceiling speed monitoring according to the speed-raising entry condition.
