Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, 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.
Fig. 1 is a schematic flow chart of a train formation method provided by the present invention. Referring to fig. 1, an embodiment of the present invention provides a train formation method, which may include: step 110, step 120 and step 130.
The execution main body of the train composition method provided by the invention can be electronic equipment, a component in the electronic equipment, an integrated circuit or a chip. The electronic device may be a mobile electronic device or a non-mobile electronic device. By way of example, the Mobile electronic device may be a Mobile phone, a tablet Computer, a notebook Computer, a palm top Computer, a vehicle-mounted electronic device, a wearable device, an Ultra-Mobile Personal Computer (UMPC), a netbook or a Personal Digital Assistant (PDA), and the like, and the non-Mobile electronic device may be a server, a Network Attached Storage (NAS), a Personal Computer (PC), and the like, and the present invention is not limited in particular.
The following describes the technical solution of the present invention in detail by taking an example in which an electronic device executes the train formation method provided by the present application.
And 110, under the condition that the first train and the second train are determined to execute a marshalling command, retracting a rear-end safety envelope of the first train and a front-end safety envelope of the second train respectively to obtain a first safety envelope of the first train and a second safety envelope of the second train.
The first train and the second train are trains in the same running direction, and the first train is located in front of the second train.
It can be understood that the embodiment of the invention can be applied to a train control center.
In step 110, the first train and the second train are two trains that normally operate on the line, and the first train operates in front of the second train. The train control center issues dynamic consist commands to the first train and the second train. The dynamic marshalling command is a marshalling command in the running state of the train.
The first train and the second train receive the dynamic consist command and confirm the execution of the dynamic consist.
In the case that it is determined that the first train and the second train execute a consist command, the first train and the second train may actively apply for changing the current train safety envelope range and obtain new safety envelopes of the two trains, i.e., the first safety envelope and the second safety envelope.
Train consist refers to the sequential order, number of cars, gross weight and length of all the cars in a train. The front and back order of the vehicles is purposefully arranged and is linked into a group, and the group is called as a marshalling.
As shown in fig. 2, fig. 2 is a schematic diagram of a train safety envelope using the train marshalling method provided by the present invention. The train safety envelope in fig. 2 is the current possible position of the train as considered by the signal system after considering the position error of the head and tail of the train.
The train safety envelope range may include four points, namely a maximum safety front end, a minimum safety front end, a maximum safety back end, a minimum safety back end.
The safety envelope for each train may include a front end safety envelope and a back end safety envelope. The front end safety envelope and the rear end safety envelope of the train can be respectively calculated according to the relevant operation parameters of the train, and the corresponding envelopes are added to the position of the train, so that the operation safety of the train can be ensured.
Therefore, the train position data sent by the vehicle-mounted equipment is used by the ground equipment after certain safety envelope processing.
The train position after the safety envelope processing is called the safety position of the train, and the train position reported to the ground equipment by the vehicle-mounted equipment is called the non-safety position of the train. Namely, the safe position of the train is obtained by actively calculating the position through the ground equipment, and the safety protection is not performed by passively utilizing the position information transmitted from the vehicle-mounted equipment.
In actual implementation, after the first train and the second train receive the marshalling command, the first train and the second train actively apply for changing the current train safety envelope range to the ground device, and after the ground device confirms, a Zone Controller (ZC) in the ground device can respectively modify the safety envelope ranges of the first train and the second train.
As shown in fig. 3, fig. 3 shows a normal running state of the train. Wherein, A is the second train, B is the first train, and the dotted line part represents the train safety envelope, and there is the safety envelope range of the first train ab, and the safety envelope range of the second train cd.
As shown in fig. 4, fig. 4 illustrates the train receiving a consist command, retracting the safety envelope. When the first train and the second train approach, both trains perform safety envelope retraction. The rear end safety envelope of the first train (front train) retracts in the running direction, and the safety envelope of the second train (rear train) retracts in the direction opposite to the running direction. At this time, the first safety envelope of the first train is AB, and the second safety envelope of the second train is CD.
And 120, determining the movement authorization information of the second train based on the first safety envelope and the second safety envelope.
As shown in fig. 3, when the train normally operates and there is a train ahead of the second train, the Movement Authorization (MA) information of the second train can be calculated up to the minimum safe rear end (point c) of the train ahead (the first train).
As shown in fig. 4, modifying the safety envelope range of the first train upon receipt of a dynamic consist command by the train may affect the MA calculation of the second train, i.e., require recalculation to determine the MA of the second train. The MA may refer to a start command of train operation, including information of distance, speed, etc. of train operation.
It should be noted that the train control center is a set of control system for ensuring the safe operation of the train, and monitors and controls the train operation speed by collecting the current operation state and the objective condition of the line of the train on the line, so that the train can safely operate on the line. The MA is a series of line track segments that a particular train can enter in a given direction. The determination of the MA is critical to whether the train can safely operate on the line.
The MA calculation device calculates obstacles which may appear in front of the corresponding train operation, such as front train route information, front train MA and the like, through counting the train positions in the district, and sends the generated MA information to a device (generally a vehicle-mounted device) with an overspeed protection function, and the overspeed protection device calculates a speed protection curve of the train according to the MA information and ensures that the train stops before the MA terminal according to a set curve.
In actual execution, the ground device ZC recalculates MA of the second train and sends MA to the second train.
And 130, linking the first train and the second train based on the mobile authorization information.
In step 130, when the first train and the second train approach, the train opens the coupling device until the coupling is completed.
It should be noted that the coupling manner of the first train and the second train may adopt a virtual coupling or a mechanical coupling.
The virtual coupling means that two trains are coupled without contact on a train body and only keep the same speed to run on a line during running, and the two trains respectively receive ZC information and Computer Interlocking (CI) information.
In some embodiments, coupling the first train and the second train comprises:
opening a first mechanical linkage of a first train and a second mechanical linkage of a second train;
and the first mechanical coupling device and the second mechanical coupling device are coupled.
In actual implementation, when the two trains approach, the first train and the second train respectively retract to the safe range, and the mechanical coupling devices are respectively opened to prepare for coupling.
As shown in fig. 5, a is the second train and B is the first train. And under the condition that the second train contacts the first train at a speed slightly higher than that of the first train, the mechanical devices of the two trains are linked, and after the linkage is successful, the rear train sends a linkage success command to a train control center, so that the mechanical linkage is completed.
The train marshalling method provided by the invention can break through the existing train marshalling mode and realize the hard coupling of the train in the running state.
In the prior art, the capacity provided by the train at each platform is certain, and the capacity arrangement cannot be made in time aiming at stations with different passenger flow volumes.
The invention can count the passenger flow of each station according to the train operation company, analyze the passenger flow at different times, arrange different train marshalling modes according to the passenger flow conditions of each station in different time periods, do not carry out dynamic marshalling processing on the station with smaller passenger flow, and arrange the dynamic marshalling mode on the station with larger passenger flow so as to meet the requirement of improving the transport capacity.
According to the train marshalling method provided by the invention, the safety envelope range of the train in the running state is modified, so that the movement authorization information can be recalculated, the train can be linked according to the new movement authorization information, and the dynamic marshalling is realized; and then can carry out the developments marshalling to the train of operation according to the freight capacity needs of different stations, be favorable to evacuating the passenger fast to satisfy the needs that improve the freight capacity.
In some embodiments, after the hitching the first train and the second train based on the mobile authorization information, the method further comprises:
under the condition that the first train and the second train are successfully linked, enabling the second train to control the first train to operate;
and sending the zone controller information and the computer interlocking information to the second train.
Under the condition that the first train and the second train are mechanically linked and the linking is successful, one train can be used as a master control train to control the operation of the marshalling train, and the data of the two trains are shared by the master control train.
In this embodiment, after the two trains are linked, the second train is used as a master control train to receive and execute ZC information and CI information, and at the same time, information such as train position and control command is shared with the first train, and the first train is controlled to operate.
The train marshalling method provided by the invention is different from a virtual coupling mode, can break through the existing train marshalling mode, realizes hard coupling in the running state of the train, has high applicability, and can be suitable for the existing CBTC system and the next generation CBTC system.
In some embodiments, retracting the back end safety envelope of the first train and the front end safety envelope of the second train, respectively, resulting in a first safety envelope for the first train and a second safety envelope for the second train, comprises:
keeping the front end safety envelope of the first train and the rear end safety envelope of the second train unchanged;
retracting the rear end safety envelope of the first train to the maximum safety rear end, and retracting the front end safety envelope of the second train to the minimum safety front end;
determining a first safety envelope based on a front end safety envelope of the first train and a maximum safety rear end of the first train;
a second safety envelope is determined based on the back end safety envelope of the second train and the minimum safety front end of the second train.
In actual implementation, when a first train and a second train approach, the ground equipment ZC specializes the safety envelopes of the two trains, and can change the envelope state of the trains in the normal running state. Namely, the front end safety envelope of the first train is kept unchanged, the front end safety envelope of the first train is retracted to the maximum safety rear end of the first train, and the rear end safety envelope of the second train is kept unchanged, and the front end safety envelope of the second train is retracted to the minimum safety front end.
It will be appreciated that the front end safety envelope of the first train may be a maximum safe front end position of the first train and the rear end safety envelope of the second train may be a maximum safe rear end position of the second train.
The train marshalling method provided by the invention can meet the requirement of executing dynamic marshalling by modifying the safety envelope range of the first train and the second train.
In some embodiments, determining movement authorization information for the second train based on the first safety envelope and the second safety envelope includes:
the mobile authorization information is determined based on a maximum safe back end of the first train and a minimum safe front end of the second train.
As shown in fig. 3, in the normal operation state of the train, the MA calculation of the rear train (second train) is limited to the traffic signal state and the minimum safe rear end position of the front train (first train).
As shown in fig. 4, in the dynamic consist state, the MA calculation of the second train is limited to the semaphore state and the maximum safe rear end position of the preceding train (the first train).
Thus, in a dynamic consist state, the MA of the second train may be determined based on the maximum safe back end of the first train and the minimum safe front end of the second train.
According to the train marshalling method provided by the invention, the envelope state of the train in the normal operation state is modified, the calculation condition of the mobile authorization information is relaxed, the dynamic marshalling is further conveniently realized, and the applicability of the dynamic marshalling can be improved.
In some embodiments, the hitching the first train and the second train based on the movement authorization information comprises:
controlling a first running speed of the first train and a second running speed of the second train based on the mobile authorization information, wherein the second running speed is greater than the first running speed, and the first running speed does not exceed a speed threshold;
and linking the first train and the second train based on the first running speed and the second running speed.
In the case where the first train and the second train perform the dynamic consist command, the first train keeps the coupled limit speed running normally, i.e., the first running speed of the first train does not exceed a speed threshold, which may be preset according to actual conditions.
And the second train chases at a second running speed higher than the first running speed, and can update the running information state of the train in real time, and the coupling device is opened to prepare for coupling when the two trains approach and meet the coupling condition.
It can be understood that the present embodiment can be applied to a scenario of cross-line operation or cross-site operation.
The train marshalling method provided by the invention can meet the requirements of different application scenes by meeting the traditional marshalling mode and carrying out dynamic marshalling in the running process of the train at the same time so as to meet the marshalling operation requirements of the next generation CBTC system.
