Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A method and apparatus for correcting a train running distance according to an embodiment of the present invention will be described below with reference to the accompanying drawings.
The method for correcting the train running distance according to the embodiment of the invention relates to a BTM, a VOBC and a transponder. Wherein, the BTM comprises a BTM host and a receiving antenna. Information interaction can be carried out between the BTM and the responder as well as the VOBC. The VOBC and the BTM are installed on a train, and the transponder is installed on a track on which the train runs. As shown in fig. 1, the serial port board on the VOBC and the BTM perform bidirectional communication through a four-wire interface (RS422), the BTM host is connected with the BTM receiving antenna through an antenna, the BTM receiving antenna receives a response message sent by the transponder when sensing the transponder, and then the response message is fed back to the VOBC through the serial port board.
Fig. 2 is a flowchart of a method for correcting a train driving distance according to an embodiment of the present invention, and as shown in fig. 2, when the execution main body is a transponder transmission unit BTM, the method for correcting a train driving distance may include:
step 101, transmitting electromagnetic waves outwards through a receiving antenna, and detecting a response message sent by a responder, wherein the response message carries identification information of the responder.
Specifically, the receiving antenna on the BTM constantly outwards launches the electromagnetic wave in the train driving process, when the train passes through and installs near the transponder top of track, the transponder receives the electromagnetic energy that BTM receiving antenna sent, thereby the electronic circuit who starts the transponder of energy conversion working power supply carries out work, then go out 1023 response message circulation that the transponder transmitted of prestored or train control central point conveying, until the electromagnetic energy disappears, when the electromagnetic energy disappears, explain the train and roll off the transponder.
Furthermore, the BTM receives a response message sent by the transponder through the receiving antenna, wherein the response message includes information required by the train control at the current road section, such as basic line information, speed limit information, station route information, and the like, so that a driver can safely control the train to run according to the response message. Meanwhile, in order to distinguish different transponders installed on the track, identification information of the transponders is carried in the response message, and the identification information of each transponder is unique in the train control system. The BTM receives a response message carrying the identification information of the responder in real time and sends the response message to the VOBC, and then the VOBC can find the accurate position of the current responder in the electronic map according to the identification information of the responder.
And step 102, after the response message is detected, in the whole process of exiting the responder, acquiring the current running distance of the train in real time according to the data frame currently received from the VOBC, wherein the data frame comprises the current speed, the current running time and the current running distance of the train.
Specifically, while the BTM transmits an electromagnetic wave to the outside through the receiving antenna and detects a response message sent by the transponder, the BTM may also periodically receive a data frame from the VOBC, where the data frame includes information such as the current running speed, running time, and running distance of the train.
Since the speed of the train changes during the running process, the VOBC can record the speed of the train through a sensor or a velometer installed on the train, calculate the current running distance of the train according to the running time at different speeds, and then send the train running information such as the current running speed, the current running time, the current running distance and the like of the train to the BTM after reaching a preset data frame sending period.
And 103, determining a first travel distance of the train at the position of the center point of the transponder.
According to the propagation characteristics of electromagnetic waves, the signal strength of a response message received by a BTM is related to the distance between the BTM and a transponder, the closer the BTM is to the transponder, the greater the signal strength of the received response message is, and in the whole process that a train drives out of the transponder, the distance between the BTM and the transponder is from far to near, when the BTM is positioned on the central point of the transponder, the closest distance between the BTM and the transponder is, and then the BTM is gradually far away from the central point of the transponder, so that the signal strength of the response message received by the BTM and the distance show a convex function relationship, the signal strength of the response message is gradually increased, and the signal strength is gradually decreased after the moment with the strongest signal strength is reached. The signal strength of the response messages at different moments is compared to determine the response message with the strongest signal strength, and the receiving moment of the response message with the strongest signal strength is obtained, and the receiving moment is the moment of the BTM on the train at the central point position of the transponder.
Further, the BTM may determine a first distance traveled by the train at the transponder center point location based on the train travel information in the received data frame. Specifically, if the receiving time is the data frame sending time, the first travel distance is the current travel distance of the train in the data frame, and since the VOBC periodically sends the data frame to the BTM, the data frame sending time may not be consistent with the receiving time, so the BTM needs to determine the first travel distance according to the train travel information in the data frame with the similar receiving time.
In one embodiment of the present invention, the BTM determines, according to the transmission time of each received data frame, that the previous data frame which is earlier than the receiving time and adjacent to the receiving time is the target data frame for calculating the first travel distance, for example, if the receiving time determined by the BTM is 2 hours 30 minutes 40 seconds, and the receiving data frame times recorded by the BTM are 2 hours 30 minutes, 2 hours 30 minutes 30 seconds and 2 hours 31 minutes, the BTM selects the data frame of 2 hours 30 minutes 30 seconds as the target data frame, and calculates the first travel distance according to the train travel information in the data frame.
Specifically, the BTM extracts the current speed and the current travel distance of the train when the data frame is transmitted from the target data frame, and then, the BTM obtains the travel distance of the train from the transmission time of the target data frame to the reception time by taking a difference between the reception time and the transmission time of the target data frame, and then, the BTM obtains the first travel distance from the train to the center point of the transponder by multiplying the difference by the current speed in the target data frame.
Therefore, the train running distance correction method provided by the invention has the advantages that the BTM judges the center point position, so that the center point position is more accurately judged, the train running distance correction precision can be improved, the train running safety is facilitated, the first distance of the train at the center point position of the transponder is calculated according to the data frame sent by the VOBC, and the train running distance is conveniently corrected in the next step.
And step 104, transmitting the first travel distance to the VOBC so that the VOBC corrects the travel distance of the train.
Since the VOBC accumulates the running distance of the train by measuring the running speed of the train in real time and combining the running time of the train during the running of the train, the error exists during the measurement of the running speed of the train, and the error is continuously accumulated in the process of accumulation calculation, so that the error of the calculated running distance is increased. If the running distance with the error calculated by the VOBC is taken as the real running distance of the train, the deviation between the current position of the train possibly calculated and the actual position of the train is large, so that a large accident risk exists in the control process of the train.
In order to reduce the risk of accidents, the driving distance calculated by the VOBC needs to be corrected, in this embodiment, a difference value between the first driving distance of the train calculated by the BTM at the center of the transponder and the driving distance of the train calculated by the VOBC at the receiving time can be made, and the driving distance of the train can be corrected by combining the accurate position of the transponder after the distance difference is calculated, so that the correction precision of the train can be improved, and the deviation between the corresponding position of the driving distance and the actual position of the train can be more accurately reduced.
As an example, the BTM sends the first travel distance to the VOBC so that the VOBC corrects the travel distance of the train according to the second travel distance corresponding to the time the first travel distance was received.
In this example, when the VOBC receives the target first travel distance sent by the BTM, the VOBC calculates the second travel distance according to the real-time train travel speed and travel time, and makes a difference between the calculated second travel distance and the target first travel distance to obtain a distance difference, which is the difference between the first travel distances that the train exceeds when the VOBC receives the first travel distance. Furthermore, because the identification information of the transponder is carried in the response message, the VOBC finds the accurate position of the current transponder in the electronic map by receiving the identification information of the transponder in the response message, and the accurate information of the transponder is the actual distance from the train departure point of the transponder marked in advance.
In this embodiment, when the VOBC receives the response message sent by the BTM, the VOBC calculates the train travel distance that exceeds the center point of the transponder, so that it is necessary to perform a fine adjustment on the precise position by using the distance difference in the calculation of the precise position. Specifically, the corrected train travel distance is obtained by adding the distance difference to the actual distance from the transponder, i.e., the distance from the departure point.
Although the corrected running distance of the train may still have a certain deviation, on the basis of the accurate position of the transponder, the deviation between the position corresponding to the running distance of the train and the actual position of the train is greatly reduced, and the accuracy of train positioning is improved.
In summary, in the method for correcting the train travel distance according to the embodiment of the present invention, the receiving antenna is used to emit the electromagnetic wave to the outside and detect the response message sent by the transponder, after the response message is received, in the whole process of moving out of the transponder, the current travel distance of the train is obtained in real time according to the data frame currently received from the vehicle-mounted control system VOBC, then the first travel distance of the train at the center point of the transponder is determined, and finally the first travel distance is sent to the VOBC, so that the VOBC corrects the travel distance of the train.
Therefore, when the method determines that the train is at the center point position of the transponder, the first travel distance of the train at the moment is sent to the VOBC, then the VOBC makes a difference value according to the first travel distance sent by the BTM and the train travel distance calculated by the VOBC at the receiving moment, the travel distance of the train is corrected by combining the accurate position of the transponder after the distance difference is calculated, the correction precision of the train can be improved, the correction of the train travel distance is carried out, the correction of the travel distance is not carried out by only depending on the VOBC, the judgment of the center point position by the BTM is increased in the correction process of the travel distance, the judgment of the center point position is more accurate, the correction precision of the train travel distance can be improved, and the travel safety of the train is facilitated.
Based on the above embodiment, in order to more clearly describe the method for correcting the train travel distance, the above method may be further explained by using the VOBC as an execution subject. Fig. 3 is a flowchart of a method for correcting a train driving distance according to another embodiment of the present invention. As shown in fig. 3, the method for correcting the train running distance includes the steps of:
step 201, periodically sending a data frame to the BTM, wherein the data frame comprises the current speed sum, the current running time and the current running distance of the train. Specifically, during the running process of the train, the VOBC periodically transmits a data frame to the BTM, wherein the data frame includes train running information such as the current speed and the current running time of the train. For the description of the running speed of the train, reference may be made to the description of the relevant contents in the above embodiments, and the description is omitted here.
Step 202, receiving a response message of the responder sent by the BTM, wherein the response message carries identification information of the responder.
Specifically, when the train is in the process of exiting the transponder, the transponder is influenced by electromagnetic waves sent by the BTM antenna to start the electronic circuit and send a response message to the BTM antenna, and the BTM antenna receives the response message sent by the transponder, wherein the response message contains information required by controlling the train on the current road section, such as basic line information, speed limit information, station route information and the like, so that a driver can safely control the train to travel according to the response message. Meanwhile, in order to distinguish different transponders installed on the track, identification information of the transponders is carried in a response message, the identification information of each transponder is unique in a train control system, the BTM sends the currently received identification information of the transponders to a VOBC (video object controller), and the VOBC finds the accurate position of the current transponder in an electronic map, so that the train running distance with errors calculated by the train is corrected.
Step 203, receiving a first driving distance sent by the BTM when the train is at the central point position of the transponder; and the first travel distance is calculated by the BTM according to the received data frame when the train is at the position of the central point of the transponder.
And 204, correcting the running distance of the train according to the first running distance and the identification information.
The VOBC searches for the accurate position of the current transponder in the electronic map to obtain the accurate distance between the center point of the transponder and the starting point, and in order to correct the running distance of the train, the first running distance of the train calculated by the BTM when the train passes through the center point of the transponder needs to be obtained.
As an example, in the whole process of exiting the transponder, the BTM may obtain the current driving distance of the train according to information, such as the current speed, the current driving time, and the current driving distance of the train, included in a data frame periodically sent by the VOBC, and then determine the receiving time of the train at the center point of the transponder according to the signal strength of the received response message. And the BTM determines the first driving distance of the train according to the train driving information in the transmitted data frame.
For the determination process of the first travel distance, reference may be made to the description of relevant contents in the above embodiments, and details are not described here.
Further, the VOBC can receive a first distance traveled by the train at the transponder center point location sent by the BTM. The VOBC can determine whether the train is at the center of the transponder based on the signal strength of the reply message sent from the BTM. And taking the calculated train running distance corresponding to the moment when the position of the central point of the transponder is determined as a second running distance.
In this embodiment, after obtaining the response packet, the BTM needs to transmit the response packet to the VOBC after a certain transmission time, so that a certain time difference exists between the time of the center point position of the transponder determined by the BTM and the time determined by the VOBC. Further, the VOBC makes a difference value between the second driving distance and the first driving distance to obtain a distance difference, and then corrects the driving distance of the train by combining the identification information of the transponder.
Specifically, the VOBC obtains the positioning distance of the transponder according to the identification information query, and adds the positioning distance and the distance difference to obtain the target running distance of the VOBC after the train passes through the correction when the center point position of the transponder is received.
In summary, in the method for correcting the train travel distance according to the embodiment of the present invention, the VOBC periodically transmits the data frame to the BTM and receives the response message of the transponder transmitted by the BTM, and then receives the first travel distance when the train transmitted by the BTM is located at the center point of the transponder, and corrects the travel distance of the train according to the first travel distance and the identification information.
Therefore, when the method determines that the train is at the center point position of the transponder, the first travel distance of the train at the moment is sent to the VOBC, then the VOBC makes a difference value according to the first travel distance sent by the BTM and the train travel distance calculated by the VOBC at the receiving moment, the travel distance of the train is corrected by combining the accurate position of the transponder after the distance difference is calculated, the correction precision of the train can be improved, the correction of the train travel distance is carried out, the correction of the travel distance is not carried out by only depending on the VOBC, the judgment of the center point position by the BTM is increased in the correction process of the travel distance, the judgment of the center point position is more accurate, the correction precision of the train travel distance can be improved, and the travel safety of the train is facilitated.

And step 303, after detecting the response message, the BTM obtains the current driving distance of the train in real time according to the data frame currently received from the VOBC in the whole process of driving out the responder.
For the description of step 303, reference may be made to the description of relevant contents in the above embodiments, which are not described herein again.
Step 304, the BTM sends the detected response message to the VOBC; wherein, the identification information of the responder is carried in the response message.
And each time the BTM detects a response message, the BTM can send the detected response message to the VOBC, so that the VOBC can extract the identification information of the responder from the response message, and further can inquire the accurate position of the responder on the electronic map.
It should be noted that step 303 and step 304 are not in sequence, and are executed in parallel. The BTM and the VOBC communicate in a full duplex mode, and the BTM can send the detected response message to the VOBC in the process of sending the data frame to the BTM by the VOBC, so that the transmission efficiency between devices is improved, and the calculation error of increasing the train running distance due to data collision is avoided.
In step 305, the BTM determines a first distance traveled by the train at the transponder center point location and sends it to the VOBC.
The BTM determines the position of the center point of the transponder according to the detected signal intensity of the response message, and further determines a first travel distance corresponding to the position of the center point. For the determination process of the center point position of the transponder, reference may be made to the description of relevant contents in the above embodiments, and details are not described here.
And step 307, the VOBC corrects the running distance of the train according to the first running distance and the identification information.
And the VOBC searches for the accurate position of the current transponder in the electronic map according to the identification information, and further can obtain the accurate distance from the center point of the transponder to the starting point. And then, according to the received first travel distance, determining a distance difference by calculating a second travel distance at the central point position of the transponder by the first travel distance, adding the distance difference and the positioned accurate distance, and correcting the travel distance of the train by using the travel distance obtained after the addition.
In this embodiment, in the process of sending a data frame to the BTM by the VOBC, the BTM can send a detected response message to the VOBC, the BTM and the VOBC communicate in a full duplex manner, when the BTM determines that the train is located at the center point of the transponder, the BTM sends the first travel distance of the train at that time to the VOBC, then the VOBC makes a difference between the first travel distance sent by the BTM and the train travel distance calculated by the VOBC at the time of receiving, and corrects the travel distance of the train in combination with the accurate position of the transponder after calculating the distance difference.
