Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The train red light running protection system based on the ground transponder comprises a vehicle-mounted ATP, an electronic map, a signal machine and a transponder group, wherein the transponder group comprises an active transponder and a plurality of passive transponders, and the passive transponders are arranged on track lines on two sides of the active transponder.
The signal machine is used for displaying the state whether the current track line allows passing, the vehicle-mounted ATP is used for acquiring message information of the passive transponder and the active transponder, the vehicle-mounted ATP acquires the active transponder when a train passes through the active transponder, and the active transponder feeds back the state of the signal machine to the vehicle-mounted ATP.
When a train runs along a track line, inquiring the first passive transponder obtained according to the vehicle-mounted ATP in an electronic map, inquiring the protection information corresponding to the passive transponder, judging whether the current running direction of the train needs to make a protection response to the state of a signal machine, and outputting emergency braking when the protection response needs to be made and the state of the signal machine fed back to the vehicle-mounted ATP by the active transponder is no-pass.
In the scheme, the automatic protection function of the red light running of the train is realized by simply modifying the annunciator and laying a small number of ground transponders, and the automatic protection system has the advantages of low construction cost, short period, easiness in realization and later maintenance; and whether the train running direction corresponds to the protection direction of the signal machine is judged by utilizing the responder group, so that whether protection response needs to be made to the state of the signal machine is judged, and unexpected emergency braking is avoided.
In this embodiment, the transponder group comprises an active transponder connected to the annunciator and a first passive transponder and a second passive transponder connected to the active transponder. As shown in fig. 1, the first passive transponder, the active transponder, and the second passive transponder are arranged in sequence at intervals along the track line.
The attributes of the transponder group described in the electronic map include at least the following:
the first passive transponder identification number B1, the front active transponder identification number VB and the distance (unit: centimeter) between the two transponders are used for protecting the state of a signal machine provided by the active transponder;
the second passive transponder identification number B2, the front active transponder identification number VB, and the distance (unit: cm) between the two transponders do not protect the state of the annunciator provided by the active transponder;
besides, the attribute of the transponder recorded in the electronic map may further include: the track to which the transponder belongs and the position in the track, the signal protection direction represented by the active transponder, whether the train running direction is the same as the signal protection direction, and the like.
All the attributes can be inquired in the electronic map by taking the received transponder identification number as an index.
In this embodiment and some other embodiments, the train red light running protection system based on ground transponders can be installed in any track area needing protection, and each annunciator can be used corresponding to one transponder group or multiple transponder groups.
Referring to fig. 1, after the train first acquires the first passive transponder, the vehicle ATP acquires the identification number B1 of the first passive transponder, so as to query the electronic map according to the identification number B1 to know that: the train receives the active transponder within a certain distance in front of the train, and makes a protection response to the state of the signal machine provided by the active transponder, wherein the train running direction is the same as the protection direction of the signal machine. That is, when the traffic signal state is no pass (red light), the vehicle-mounted ATP outputs emergency braking; when the traffic signal state is the traffic permission (green light), the vehicle-mounted ATP does not output the emergency brake, and the train continues to run. After the train firstly acquires the second passive transponder, the following information is obtained by inquiring the electronic map: the protection response is not made to the state of the signal machine provided by the active transponder, the running direction of the train is opposite to the protection direction of the signal machine, and the train runs as usual.
Furthermore, the electronic map can be inquired according to the acquired identification number of the passive transponder or the active transponder to acquire the corresponding position information, so that the train position is positioned or corrected.
The protection system further comprises a transponder transmission module, and the transponder transmission module is used for receiving the message signals of the transponder group and feeding the message signals back to the vehicle-mounted ATP for analysis.
Furthermore, the protection system also comprises an interlocking system and an automatic train supervision system, wherein the interlocking system is used for operating the annunciators and the switches on the track lines, realizing an interlocking function and supervising the train operation, the ground interlocking system judges the line conditions and controls the states of the ground annunciators, and meanwhile, the states of the annunciators are sent to the active transponders. The transponder transmission module comprises an antenna arranged on the train, and when the antenna of the transponder transmission module crosses the transponder, the vehicle-mounted ATP receives the state of the signal machine; the automatic train supervision system is used for monitoring and tracking the running condition of the train in a centralized manner and realizing train operation command and scheduling.
Preferably, the vehicle-mounted ATP also has the effect of overspeed protection, and when the vehicle-mounted ATP is restarted (after restarting or re-keying, the same applies hereinafter), the driving mode is an RM mode (Restricted Manual driving mode, the same applies hereinafter), wherein the maximum operating speed of the RM mode is a configurable fixed value. In this mode, the vehicle-mounted ATP limits the train to run at a certain fixed low speed (which should not be greater than the inbound speed limit and not greater than the lateral turnout speed limit), the driver shows to drive the train according to the dispatching command and the ground signal, and when the train runs at a speed higher than the fixed speed, the vehicle-mounted equipment applies emergency braking to the train to force the train to stop. The running safety of the train is ensured by the interlocking equipment, the vehicle-mounted ATP, the dispatching personnel and the driver together.
When the driving Mode is changed from the RM Mode to the PM Mode (Position Mode, positioning Mode, the same below), the vehicle-mounted equipment acquires the speed limit information of the front line stored in the electronic map according to the positioning of the vehicle-mounted equipment, generates a ceiling speed protection curve, limits the train to run under the protection curve, and a driver displays the running according to a ground signal. When the train runs beyond the protection curve, the vehicle-mounted equipment implements emergency braking on the train and forces the train to stop.
Preferably, in this embodiment, when the protection system acts on the station platform, as shown in fig. 2, the number of the transponder groups is two, and the two transponder groups are disposed at the exit of the station platform along the track line at a certain distance, and the protection process is as follows:
a) when the train I stops at the platform, after the vehicle-mounted ATP is restarted, the train I runs towards the outbound direction and continuously receives the first passive transponder B1 and the active transponder VB1, if the red light message is sent by the active transponder VB1, the train I immediately implements emergency braking, the driving mode is kept in an RM mode, at the moment, the train I crosses the annunciator O1 to enter the section A and stops before the annunciator O2, and the system ensures that the train I cannot cross the annunciator O2, so that the risk that the train I tailors the train II is avoided. If the train II is in the section B, a free protection section (the section A) behind the train II can be protected by ground interlocking, the signal machines O1 and O2 both display red lights, the train I is normally stopped before the signal machine O1 under the control of a driver, and if the train I is not stopped before the signal machine O1 due to abnormality, the train I is forced to stop in the section A by the signal machine O2 and the corresponding other responder group, and double protection is realized.
b) When the train I stops at the platform, after the vehicle-mounted ATP is restarted, the train runs in the outbound direction and continuously receives the first passive responder B1 and the active responder VB1, if the active responder VB1 sends a green light message, the train is upgraded to the PM mode, the train can normally exit, and the ATP protects the train from normal running.
c) When the train I stopped at the platform is restarted, the train runs in the outbound direction, only receives the first passive transponder B1 and does not receive the active transponder VB1, the train I judges that the emergency braking is carried out immediately after the transponder is lost by calculating the distance between the train and the active transponder VB1, and the driving mode is kept in the RM mode.
d) When the train I stops at the platform, after the vehicle-mounted ATP is restarted, the train runs in the outbound direction, only the active transponder VB1 is received, and the first passive transponder B1 is not received, if the active transponder VB1 sends a green light message, the train normally crosses the outbound signal machine in an RM mode, and the driving mode is kept in the RM mode.
e) When the train I stops at the platform, after the vehicle-mounted ATP is restarted, the train runs in the outbound direction, only the active transponder VB1 is received, and the first passive transponder B1 is not received, if the red light message is sent by the active transponder VB1, the train immediately implements emergency braking, and the driving mode is kept in the RM mode.
f) When the train I stopped at the platform is restarted and runs in the outbound direction without receiving the active transponder VB1 and the first passive transponder B1 after the ATP on the train is restarted, the train normally passes over the outbound signal in the RM mode, and the driving mode is kept in the RM mode.
g) When the current driving mode of the train I stopped at the platform is PM, the train runs towards the outbound direction and continuously receives the first passive transponder B1 and the active transponder VB1, if the active transponder VB1 sends red light messages, the train immediately implements emergency braking, the driving mode is reduced to RM mode, and if the active transponder VB1 sends green light messages, the train keeps PM mode to cross the outbound signal machine.
h) And when the current driving mode of the train I stopped at the platform is PM, the train runs in the outbound direction, and the active transponder VB1 is not received within the distance range of the active transponder VB1, the train I judges that the transponder is lost, outputs emergency braking and falls to the RM mode.
The train red light running protection system based on the ground transponder further introduces a train red light running protection method based on the ground transponder, which comprises the following steps:
s1: acquiring message signals of a red light running protection transponder group corresponding to a railway line side signal machine in the running process of the train;
based on the train red light running protection system based on the ground transponder, the transponder group comprises a first passive transponder, an active transponder and a second passive transponder which are sequentially arranged; the active transponder is connected with the signal machine and sends the state of the signal machine to vehicle-mounted equipment on the train, wherein the vehicle-mounted equipment is vehicle-mounted ATP. When the train travels to the transponder transmission module antenna on the train to cross the active transponder, the train receives the status of the transponder.
Firstly, the method comprises the following steps: train no-positioning
S2: and inquiring an electronic map according to the acquired first passive transponder, and judging whether the current direction of the train passing through the transponder group needs to make a protection response to the state of the annunciator.
As can be seen from the above-mentioned train red light running protection system based on ground transponders, the attributes of the transponder group recorded in the electronic map include at least the following:
the first passive transponder identification number, the front active transponder identification number and the distance (unit: centimeter) between the two transponders protect the state of a signal machine provided by the active transponder;
the second passive transponder identification number, the front active transponder identification number, and the distance (unit: cm) between the two transponders do not protect the state of the annunciator provided by the active transponder.
In step S2, the method specifically includes:
1) the train travels from left to right in the direction shown in fig. 1
S211: the on-board ATP acquires the first passive transponder B1.
S212: and inquiring an electronic map according to the identification number B1 to know that the active transponder is received within a certain distance in front of the running train, and judging that a protection response needs to be made to the state of the annunciator provided by the active transponder.
S213: the train continues to run rightwards, the vehicle-mounted ATP receives the active transponder VB, if the state of the signal machine provided by the active transponder VB is no-pass (the protection direction of the signal machine is from left to right), the vehicle-mounted ATP receives the passive transponder B1 in advance, and the condition that the protection response is needed is known, so the vehicle-mounted ATP implements emergency braking to prevent the train from crossing the signal machine; if the state of the signal provided by the active transponder VB is the permission state, the continuous operation of the train is not influenced.
Based on the above, it should be noted that, if the train travels the distance S after receiving the passive transponder B1, the vehicle-mounted ATP still does not receive the active transponder VB or receives other transponders, and the vehicle-mounted ATP outputs the emergency brake according to the fail-safe principle, so as to avoid the occurrence of errors.
S214: and when the vehicle-mounted ATP receives the passive transponder B2, the vehicle-mounted ATP judges that the train passes through the whole red light running transponder group, and the function is ended.
2) The train runs from right to left in figure 1
S221: the vehicle-mounted ATP acquisition second passive transponder B2;
s222: and inquiring the electronic map according to the identification number B2 to know that the active transponder is received within a certain distance in front of the running train, and judging that no protection response is required to be made on the state of the signal machine provided by the active transponder.
S223: after the train continues to run leftwards, and the vehicle-mounted ATP receives the active transponder VB, although the state of the signal machine provided by the active transponder VB is forbidden to pass (from left to right relative to the protection direction), the vehicle-mounted ATP knows in advance that the state of the signal machine is not protected, so the vehicle-mounted ATP does not implement emergency braking, and unexpected emergency braking is avoided.
In addition, an electronic map can be inquired according to the acquired passive transponder or active transponder, so that the train position can be positioned or corrected.
Based on the above, it should be noted that if the train travels the distance S after receiving B2, the vehicle ATP still does not receive the active transponder VB or receives other transponders, and the vehicle ATP outputs emergency braking according to the fail-safe principle.
S224: and when the vehicle-mounted ATP receives the passive transponder B1, the vehicle-mounted ATP judges that the train passes through the whole red light running transponder group, and the function is ended.
Further, the train also includes the situation that the train has the location when the train is running, as follows:
II, secondly: train has location
When the train is operating on the main track and the train is positioned mostly at this time, the positioning may be performed according to the above-mentioned steps S2 (S211 to S214 or S221 to S224). And when the vehicle-mounted ATP receives the active transponder in the transponder group, inquiring the attribute of the signal machine protection direction represented by the active transponder through the vehicle-mounted electronic map, if the train running direction is consistent with the protection direction, then protecting according to the state information of the signal machine, and if the train running direction is inconsistent with the protection direction, not protecting. The red light running protection function does not influence the original function of train positioning and position correction by utilizing the position of the transponder by the vehicle-mounted ATP.
Under the condition that the train is positioned, the two methods of receiving the sequence of the transponders and judging whether the directions are consistent can be mutually supplemented and verified. Such as the following two examples:
1) when a train is positioned, the vehicle-mounted ATP firstly receives the first passive transponder (for protecting the annunciator), but then receives the active transponder, after the active transponder is inquired, the running direction of the train is confirmed to be inconsistent with the protection direction of the active transponder (without protecting the state of the annunciator), so that the judgment error of the positioning (running direction) of the train or the error of the electronic map is indicated, and the vehicle-mounted ATP is required to immediately output emergency braking for safety.
2) When the train is positioned, the vehicle-mounted ATP judges that the protection direction of the annunciator is consistent with the running direction of the train after receiving the active transponder, but then receives the first passive transponder of the transponder, the judgment of the positioning (running direction) of the train or the error of the electronic map is indicated, and the vehicle-mounted ATP outputs emergency braking immediately for safety.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
