Description
Technical Field
The invention relates to the technical field of rail transit, in particular to a method and a device for detecting train point reporting time.
Background
An Automatic Train monitoring system (ATS system) for urban rail transit is a command system with a high degree of automation. In the rail transit operation process, generally, the train is automatically operated through a planned programmed operation diagram. But the actual trajectory of the train does not follow the map exactly. Therefore, a real-track operation map is required in the ATS system to record the real train operation. The train station reporting time detection, namely train station reporting detection, refers to the specific time for detecting the train station reporting to and from, so as to update the time nodes of the finished train operation diagram part, thereby updating the operation diagram and finishing the corresponding operation diagram adjustment according to the actual situation. Train in and out station report detection belongs to a part of train operation diagram adjusting function. The time of reporting the point when the train enters or leaves the station can be divided into the time of arriving at the departure point and the time of passing the point according to the stop or passing of the train at the station. The arrival point and departure point time can be divided into an arrival point time and a departure point time.
At present, an ATS system corrects the actual running condition of a train by detecting the time of arrival of the train, and the time of arrival and departure of the train is obtained by information of train identification and tracking. The information of train identification and tracking comprises information of train identification number change, information of track equipment change representation, information of train stopping and starting and the like. The existing train station entering and exiting report time detection method obtains the train station entering and exiting report time based on the information, and specifically determines the report time by judging the situations of appearance, movement and disappearance of a train identification number on a track section and the stopping situation of the train. For example, if a train arrives at a station track and is stationary, the arrival point time may be determined; if the train drives away from the platform, the station time can be determined; if there is no tie-down condition, the train may be determined to be passing the station. The method is realized by detecting the position of the train head, but the point reporting information is not accurate enough by using the train head, and the judgment of the stop and the passing of the train is easy to generate deviation when the train stops at the station for a long time but cannot judge the stable stop state.

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.
In order to overcome the above problems in the prior art, embodiments of the present invention provide a method and an apparatus for detecting a train point reporting time, wherein the method and apparatus are designed to determine that a train is stopped stably according to information of a train head, and also according to information of opening and closing of a shield door and information of time when a train tail of a target train enters a logical section of a station track, so that the method and apparatus can determine that the train is stopped stably more accurately, and are suitable for more kinds of actual operation conditions of trains, and accuracy of point reporting information can be improved.
Fig. 1 is a schematic flow chart of a method for detecting a train time of arrival report according to an embodiment of the present invention. The following describes a train time-to-point detection method according to an embodiment of the present invention with reference to fig. 1. As shown in fig. 1, the method includes: and S101, determining that the head of the target train drives into the logical section of the track of the target station, and if the stop of the target train cannot be known according to the train event information, judging whether the target train is stopped stably or not according to the opening and closing information of the shielded gate and/or the time information of the tail of the target train entering the logical section of the track.
Specifically, whether the locomotive of the target train drives into the logical section of the track of the target station or not can be judged according to the relevant information of the locomotive.
The information related to the train head may include position information of the train head or a train identification number.
For example, the position information of the head of the target train falls into the position section covered by the logical section of the target station track, and it can be determined that the head of the target train enters the logical section of the target station track.
The relevant information of the locomotive can be obtained through a monitoring device in a logic section of a station track of a target station.
It should be noted that the target station track logical section may be determined according to the actual situation of the station, and is not specifically limited in the embodiment of the present invention.
Train event information can be obtained by monitoring the state of the train head.
The train event information may include: position information of the head of the train, speed information of the head of the train, and the like.
And judging whether the target train is stably stopped or not according to the train event information.
The loss of train event information can cause that the train stops at a station for a long time but cannot be judged to be stable, and the judgment on stopping and passing generates deviation, for example: the position information of the head of the target train cannot be obtained or the current speed information of the head of the target train cannot be obtained.
When the head of the target train drives into the logical section of the track of the target station and the target train is not known to be stopped stably according to the train event information, the target train can be judged to be stopped stably by the opening and closing information of the shielding door or the time information of the tail of the target train entering the logical section of the track, and the target train can also be judged to be stopped stably by combining the two judgment modes.
The opening and closing information of the shield door may include: the opening and closing information of the shield door and the state of the train in the station have corresponding relations, such as the opening time of the shield door, the closing time of the shield door or the opening and closing time of the shield door.
Specifically, the shield door can respond according to the state of the train at the station, and the method comprises the following steps:
after the train arrives at the station and stops stably, the shielding door is changed from a closed state to an open state;
when the train passes through the station, the shielding door is not opened and is always kept in a closed state;
before the train departs from the station, the shielding door is changed from an open state to a closed state.
The shielding door responds according to the state of the train in the station, so that whether the target train is stably stopped in the target station can be judged according to the opening and closing information of the shielding door.
If the shielding door is changed from a closed state to an open state, the stability of the target train can be judged;
if the shielding door is changed from the open state to the closed state, the departure of the target train can be judged;
if the shielding door is not opened and is always kept in a closed state, the passing of the target train can be judged.
The time information that the tail of the target train enters the station logic section may include: the time when the tail of the target train enters the track logical section, the time when the tail of the target train exits the track logical section, the time when the tail of the target train enters the track logical section, and the like.
According to the time information that the tail of the target train enters the station track logic zone, the state of the target train in the station can be judged.
Specifically, if the target train enters the target station and is stopped stably, the tail of the target train gradually decelerates to zero speed after entering the track logic section, and the zero speed is maintained for a period of time, so that the time for the tail of the target train to enter the track logic section is relatively long in the process.
If the target train enters the target station and is not stopped stably, the tail of the target train enters the track logical zone and then passes through the track logical zone at a certain speed, and the time for the tail of the target train to enter the track logical zone is relatively short in the process.
And S102, if the judgment result is that the target train is stopped stably, acquiring the arrival point moment of the target train according to the opening and closing information of the shielded gate or the time information of the tail of the target train entering the station track logic section.
After the situation that the head of the target train drives into the logical section of the track of the target station is determined, the stop and stability of the target train cannot be obtained according to the train event information, after the stop and stability of the target train is determined through the opening and closing information of the shielded gate and/or the time information that the tail of the target train enters the logical section of the track, the arrival point moment of the target train can be obtained according to the opening and closing information of the shielded gate or the time information that the tail of the target train enters the logical section of the track.
After the arrival point time is obtained, the arrival point time can be reported according to the point reporting requirement.
According to the method and the device, under the condition that the stop of the target train cannot be known according to the train event information, whether the target train is stopped stably or not is determined and the arrival point time of the target train is obtained according to the opening and closing information of the shielded door and/or the time information of the tail of the target train entering the logical section of the station track, the stop of the target train can be accurately judged according to the opening and closing information of the shielded door and/or the relevant information of the tail of the target train, the accuracy of point reporting time can be improved, and the deviation of judgment on the stop and the passing of the target train when the stop state cannot be judged due to long stop time of the target train at the station can be avoided.
Based on the content of the foregoing embodiments, if the determination result is that the target train is stopped stably, after obtaining the arrival point time of the target train according to the opening and closing information of the shielded door or the time information when the tail of the target train enters the logical section of the track, the method further includes: and acquiring the departure point moment of the target train according to the time information of the train head of the target train running out of the logic section of the station track or the opening and closing information of the shield door.
After the target train stops stably at the station, the head of the target train is positioned at a certain position of the track logic section and is still; and when the target train starts, the head of the target train leaves the position and drives out the track logical section. Therefore, the departure point time of the target train can be obtained according to the time information of the train head of the target train driving out of the logical section of the station track.
The time information of the train head of the target train moving out of the track logical section may include: the time when the head of the target train moves out of the logical section of the track, and the like. The time when the head of the target train moves out of the logical section of the station track can be obtained and used as the departure point time of the target train.
The opening and closing information of the station shielding door corresponds to the state of the train in the station.
Specifically, before the train leaves the station for departure, the station shielding door can respond in a short time, and the station shielding door is changed from an open state to a closed state.
Therefore, the departure point time of the target train can be obtained according to the time when the target station shielding door is changed from the open state to the closed state.
After the departure point time is obtained, the departure point time can be reported according to the point reporting requirement.
According to the embodiment of the invention, after the target train is judged and acquired to be stable and the arrival point time is acquired, the departure point time of the target train is acquired according to the time information of the train head of the target train running out of the logic section of the station track or the opening and closing information of the shield door, the departure point time can be acquired more accurately by detecting the relevant information of the train head of the target train or the shield door, and the accuracy of the point reporting time can be improved.
Based on the content of the above embodiments, after determining whether the target train is stopped stably according to the opening and closing information of the shield door and/or the time information of the tail of the target train entering the logical section of the station track, the method further includes: and if the judgment result is that the target train is not stopped stably, acquiring the passing point moment of the target train according to the time information of the train head of the target train entering the logical section of the track and the time information of the train head of the target train exiting the logical section of the track.
When the head of the target train drives into the logical section of the track of the target station and the target train is not known to be stopped stably according to the train event information, whether the target train is stopped stably or not can be judged by the opening and closing information of the shielding door or the time information of the tail of the target train entering the logical section of the track, and whether the target train is stopped stably or not can be judged by combining the two judging modes.
Specifically, the shield door can complete corresponding opening and closing according to the state of the train in the station. When the train arrives at the station and is not stopped stably, the shielding door does not respond, and the shielding door is always kept in a closed state.
The locomotive of the target train drives into the logical section of the track of the target station, and when the target train is not known to be stopped stably according to the train event information, whether the shielding door of the target station keeps a closed state all the time can be judged according to the opening and closing information of the shielding door. If yes, the target train can be judged and known not to be stably stopped.
The time information of the tail of the target train entering the station logic section can describe the state of the target train in the target station, for example: if the time length for the tail of the target train to enter the track logical zone does not reach the preset time length threshold value, or the time length for the tail of the target train to enter the track logical zone reaches the preset time length threshold value and the head of the target train to exit the track logical zone, the target train can be judged and known to be not stopped stably.
After the target train is judged and acquired to be not stably stopped by the method, the entering time of the head of the target train entering the logical section of the track and the exiting time of the head of the target train exiting the logical section of the track can be acquired. And acquiring the intermediate time between the driving-out time and the driving-in time as the passing point time of the target train.
After the passing point time is obtained, the passing point time can be reported according to the point reporting requirement.
According to the embodiment of the invention, when the target train is not stably stopped can not be obtained according to the train event information, the target train is determined not to be stably stopped according to the opening and closing information of the shield door and/or the time information of the tail of the target train entering the track logical section, the entering time of the head of the target train entering the track logical section and the exiting time of the head of the target train exiting the track logical section are obtained, the passing point time of the target train can be more accurately obtained, the accuracy of the point reporting time can be improved, and the deviation of the passing judgment can be avoided when the target train cannot be judged in the stable stop state due to long stop time at a station.
Based on the content of each embodiment, the specific step of judging whether the target train is stopped stably according to the opening and closing information of the shielded door and/or the time information of the tail of the target train entering the station track logical section includes: and if the opening of the shielding door is judged and known according to the opening and closing information of the shielding door, determining the judgment result as the target train is stable.
The shield door can complete corresponding opening and closing according to the state of the train in the station.
Specifically, after the train arrives at the station and is stably stopped, the shielding door responds, and the closed state is changed into the open state.
The locomotive of the target train drives into the logical section of the track of the target station, and when the target train is not known to be stopped stably according to the train event information, whether the shield door of the target station is changed from a closed state to an open state or not can be judged according to the opening and closing information of the shield door. If so, the target train may be determined to be stationary.
After the embodiment of the invention determines that the target train is stopped stably, when whether the target train is stopped stably cannot be judged according to the head state of the target train, the method can determine that the target train is stopped stably by detecting the opening of the shielding door, can judge that the target train is stopped stably more accurately, can improve the accuracy of point reporting information, and can avoid deviation of judgment on stop and passing of the target train when the stop state cannot be judged due to long stop time of the target train at a station.
Based on the content of each embodiment, the specific step of determining whether the target train is stopped stably according to the opening and closing information of the shielded door and/or the time information of the tail of the target train entering the logical section of the station track further includes: and if the shielding door is judged and known not to be opened according to the opening and closing information of the shielding door, judging whether the time length of the tail of the target train entering the track logical section reaches a preset time length threshold value or not, and judging whether the head of the target train exits the track logical section or not.
The train protection method includes the steps that the head of a target train drives into a track logic section of a target station, when the target train cannot be known to be stopped stably according to train event information, if the shielding door is judged and known not to be opened according to opening and closing information of the shielding door, the time when the tail of the target train enters the track logic section and the current time can be obtained.
And the time length of the train tail entering the station track logic section is equal to the current time-the time when the train tail of the target train enters the station track logic section.
If the time length for the tail of the target train to enter the station track logical zone reaches the preset time length threshold value, the locomotive position information of the target train can be obtained, and whether the locomotive of the target train is driven out of the station track logical zone is judged according to the locomotive position information of the target train.
It should be noted that, the tail of the target train enters the track logical section, and the head of the target train does not exit the track logical section, and the distance traveled by the target train is: the difference between the length of the track logical section and the length of the target train.
The preset time threshold may be determined according to the actual situation of train operation, for example: may be determined based on less than the length of time required for the train to maintain the minimum speed through the distance. The specific value of the preset duration threshold is not specifically limited in the embodiment of the present invention.
If the time length that the tail of the target train enters the station track logical zone reaches the preset time length threshold value, the target train is in a stable stopping state after the tail of the target train enters the station track logical zone, and therefore the target train is determined to be stable stopping.
If the shield door is determined not to be opened, the method determines that the time for the tail of the target train to enter the track logical section reaches the preset time threshold value through judgment, and the head of the target train does not run out of the track logical section, determines the stop stability of the target train, and can judge the stop stability of the target train through the time information for the tail of the target train to enter the track logical section when the stop stability of the target train cannot be judged according to the detection of the head state of the target train and the opening and closing information of the shield door, so that the stop stability of the target train can be judged more accurately, the accuracy of the point reporting time can be improved, and the deviation of the stop and the passing judgment can be avoided when the stop stability of the target train cannot be judged after the stop time of the target train is longer.
Based on the content of each embodiment, the specific step of obtaining the arrival point time of the target train according to the opening and closing information of the shielded gate or the time information of the tail of the target train entering the track logical section includes: and if the judgment result is determined as the stop and stability of the target train according to the opening of the shield door, acquiring the moment of opening the shield door as the arrival point moment of the target train.
The shielding door can complete corresponding opening and closing according to the state of the train at the station.
Specifically, after the train arrives at the station, the shield door can respond in a short time and change from a closed state to an open state.
Therefore, the time when the target station shield door is opened can be obtained as the arrival point time of the target train.
And the moment when the target station shielding door is opened, namely the moment when the target station shielding door is changed from a closed state to an opened state.
It should be noted that after the time when the target station platform screen door is changed from the closed state to the open state is obtained, the time when the target station platform screen door is changed from the closed state to the open state may be subtracted by a preset correction time delay to obtain the arrival point time of the target train.
The preset correction time delay can be determined according to the actual condition of train operation. The specific value of the preset correction delay is not specifically limited in the embodiment of the present invention.
It should be noted that the influence of the response time of the shield door on the arrival point time of the target train is negligible.
