Background

If the urban rail transit signal system has a cascading failure, an automatic blocking driving method needs to be replaced by a telephone blocking driving method. The blocking is to ensure that only one train runs in the interval between two adjacent stations or a designated blocking interval, thereby ensuring the running safety. Telephone blocking refers to a method of performing communication through a telephone to thereby implement blocking. The telephone blocking method is inherited from national railways, the subject idea is to ensure safe driving, and all links are designed conservatively.

At the initial stage of putting a new line into operation, the safety and the stability of a signal system are still in continuous perfection, so that the probability that a signal device breaks down and a vehicle is organized by adopting a telephone blocking method is objectively increased. Meanwhile, at the initial stage of opening a new line, the service level of the driving commander needs to be improved, the personnel need to be run in, and the risk of organizing driving by adopting a telephone blocking method is further increased.

In addition, the current telephone blocking method can only use an actual train for drilling, can only carry out drilling through night off-time, needs to coordinate time and resources of each party participating in the drilling, is high in drilling cost, occupies precious night construction time, and cannot achieve reasonable distribution of drilling and construction.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of methods consistent with certain aspects of the invention, as detailed in the appended claims.

The urban rail transit driving assistance system provided by the application is explained in detail through specific embodiments.

First, a brief introduction is made to a usage scenario of the present solution.

If the automatic blocking fails, the central workstation and the station workstation cannot monitor the line running vehicles, so that the train position cannot be monitored by both the train dispatcher and the station attendant, and generally, after the signal linkage fails, the automatic driving method is stopped and the driving is organized by using a telephone blocking method to solve the problem of monitoring the train position. The telephone blocking method is used as a basic blocking mode in rail transit operation, and the operation process is relatively mature. According to statistical data, accidents occurring in the train receiving and dispatching under abnormal conditions account for 49.1% of the total number of accidents occurring in the train receiving and dispatching, so how to quickly and effectively carry out telephone blocking to arrange the train receiving and dispatching under abnormal conditions becomes an important problem for rail traffic development.

The key content for improving the safety of the telephone blocking method is how to accurately position the train, determine the command issuing time and prevent accidents through mutual control among a train dispatcher, a driver and a station attendant in the process of converting the automatic blocking method into the telephone blocking method.

The rail transit operation system generally includes a central control center, a station control center and a rail train, wherein the central control center is arranged with a traffic signal, the station control center is arranged with a station attendant, and the rail train is arranged with a driver, and the telephone blocking is implemented based on the traffic signal, the station attendant and the telephone communication between the drivers.

The existing telephone blocking method comprises three stages: start, run, and cancel. The existing telephone blocking method comprises the following processes:

1. initiation of telephone blocking method

(1) If a part of linked signal systems in a driving area are in fault, a line dispatching determines a telephone blocking method section, informs a corresponding driver to stop by telephone, simultaneously displays the number of trains in a normal area of a confirmed signal system through an Automatic Train monitoring system (ATS) so as to obtain the number of trains in a telephone blocking area (the number of the trains in the normal area is subtracted from the number of the trains in an online Train), and checks the Train number and the stop position of the Train line by line according to the sequence of the Train number of the ascending and descending to avoid positioning omission.

(2.1) the mobile block is degraded into a telephone block, the train in the section for implementing the telephone block is switched into a Restricted manual driving mode (RM) by the dispatching command, the train is operated to a platform in front of the section for parking and standby by a visual train operation method (the train can be parked at any time), the driver of the train operating according to the visual train operation method needs to pay attention to the safety of operation, if the continuous operation condition is not met, the train should be immediately parked, the dispatching command is reported, if the train is parked in the telephone block section, the train should be operated to the platform in front by visual observation after the platform in front is cleared.

And (2.2) degrading the telephone blocking method by an automatic inter-station blocking method, and calling the on-line train drivers to stop and wait at the platform in front of the located section by a line calling group.

(3) During the positioning of the train, the train dispatching can be carried out on the whole train, the train starting time is adjusted, and the train running interval of the non-telephone block section is controlled. In order to reduce the influence on the passenger transportation organization, the car-holding time can not exceed 5 minutes in principle, and if the telephone blocking can not be started within 5 minutes, the train in the non-telephone blocking area should be organized to continue running at the right moment.

(4) After the train parking positions are checked by the traveling dispatching and all drivers, the train number and the parking positions are checked by all stations in the full call blocking method area and the station watchmen row by row according to the sequence of the traveling number and the traveling number. If the train stops in the section, after the telephone block is started, the station receiving station in front of the section train operation must be allowed to agree with the block request of the station receiving station after all the section trains leave the station platform.

If the turning-back station is in the telephone block section, the line dispatching timely informs signal dispatching and the turning-back station prepares for hand-operated turnout on a lower rail.

(5) Station personnel prepare driving tools such as road tickets, signal flags/lamps and the like, and station platform vehicle receiving personnel are in place in time; and the line alignment preparation is a tool for manually laying and drawing a train working diagram.

(6) The dispatching order issues the dispatching order of starting the telephone blocking method to the driver and the station at the same time, and the dispatching order is the interval for executing the telephone blocking method. The scheduling commands are in the form of spoken and electronic scheduling commands.

2. Operation of telephone blocking method

(1) Request blocking

After the dispatching command of starting the telephone blocking method for dispatching is finished, the station attendant can request blocking for the station stop train to the front station.

In the process of organizing the traveling according to the telephone blocking method, after receiving the report point sent by the train at the adjacent departure station, the attendant at the intermediate station in the telephone blocking section confirms that the departure route is ready, namely requests the adjacent station for blocking. When the train arrives at the station, the station of origin of the telephone block section confirms that the departure route is ready, and requests the adjacent station for blocking.

(2) Consent occlusion

After checking that the idle conditions of 'one station and one interval' (the intervals of the receiving station platform, the departure station and the receiving station are idle), the receiving station attendant confirms that the platform of the station is idle, the receiving station access route is ready to be appropriate, and the ticket of the train in the previous time is cancelled (except for the first time of telephone block), the receiving station attendant can agree with the block request of the departure station.

After receiving the blocking request of the departure station, the station attendant immediately gives a reply of disapproval blocking if the station does not have the condition of receiving the train; once the station has the condition of receiving the train, the station actively contacts with the departure station to handle the telephone block.

(3) Filling in road ticket

The attendant at the departure station registers the blocked phone records agreed by the receiving station, namely, the ticket can be filled in after the log of the station driving work is written. The road ticket can be filled in by a platform safety staff at the platform according to the instruction of a station attendant, and after the filling is finished, the road ticket is repeated by the two parties so as to ensure the accuracy of information transmission. The station attendant signs the road ticket and adds the station stamp. The road ticket filling needs clear writing and cannot be corrected, the road ticket is duplicated, the driver is handed in the forward direction, and the auxiliary vehicle is reserved in the auxiliary vehicle station.

(4) Exchange road ticket

Before delivering the road ticket to the driver, the safety staff at the station platform needs to check the written contents of the road ticket item by item and repeat the written contents with the driver again to ensure that the written contents of the road ticket are correct. Except for the starting station, the platform security officer can give the driver the road ticket of the station after the road ticket in the driver is recovered. After the train is sent out, the platform security officer should report the information of the train sending out and receiving back to the station attendant. The recovered road ticket can be cancelled by marking X, and the station is kept.

(5) Reading road ticket

The road ticket is the only certificate for the driver to drive the subway train to enter the area, and the driver needs to read the road ticket carefully after receiving the road ticket and check the number, the area and the station mark of the road ticket with the platform security officer.

(6) Determining departure

The platform security officer can send out a train hand signal to the train when confirming that the ticket handover operation is finished and the train door closing operation is finished, and the driver can send out the train according to the hand signal and drive the train to enter the section.

(7) Starting point

After the train is sent out from the station, the station attendant records the time point of the departure of the train from the station on a station driving work log, immediately reports the departure time to the receiving station and reports the departure time to the train dispatching station.

If the station implementing telephone blocking is the station connecting with the section yard, when the station meets the condition of getting off the line of the train and returning to the section (yard), after the returning section train completely passes through the section (yard) signal machine, the section (yard) signal building shall report the train section (yard) entering time to the rail connecting station.

3. Cancellation of telephone blocking method

(1) After the row call receives the report about the signal equipment fault recovery from the signal specialty, the station signal equipment should be confirmed to be recovered to normal with the relevant station attendant.

(2) And the on-line train number and position can be checked according to the drawn train running diagram and the ATS display, and a scheduling command for recovering the basic occlusion method can be issued after the condition for recovering the basic occlusion method is confirmed.

(3) And the dispatching or station attendant recovers the automatic route and the automatic turn-back of the train and recovers the running of the train by the basic blocking method.

(4) After the basic blocking method driving is recovered, the operation regulation should be orderly organized according to the train operation diagram implemented on the day and the actual situation to recover the operation.

(5) And the station cancels the handled block after receiving the dispatching command, and the block is automatically removed after the train arrives at the station after the train has run in the section.

(6) After receiving the dispatching command, the train driver should resume normal driving mode operation according to the signal display.

The existing telephone blocking method has many communication links, complex procedures and high staff pressure, so the probability of safety accidents caused by errors of the traffic commander is reduced by improving the telephone blocking operation flow, the driving organization capability of the traffic commander under abnormal conditions is improved, and the method has very important practical significance and is a non-negligible part in the system construction and development of urban rail transit enterprises.

Fig. 4 shows a flow chart of the operation of the traffic method with telephone block, as shown in fig. 4, in this example, the traffic key monitors the situation of the operating area, and if a chain signal system of a part of the area fails, the traffic key starts the telephone blocking method, the telephone blocking subsystem implements the telephone blocking start, operation and cancellation through the communication subsystem, specifically, in the event of a signal chain failure condition of the traffic route, the auxiliary system for urban rail transit vehicle is configured to perform:

(1) and the central console sends a telephone blocking starting instruction to the background server.

The line tone acquires a fault section through a central console, and determines a telephone blocking method section according to the fault section, wherein the determination method of the telephone blocking method section can be any method in the prior art for determining the telephone blocking method section according to the fault section.

And the line tone sends a telephone blocking starting instruction to the background server at the central console.

(2) And the background server receives the telephone blocking starting instruction and forwards the instruction to the driver handheld terminal and the station control console.

In this example, the background server receives the telephone blocking starting instruction and forwards the telephone blocking starting instruction to all driver handheld terminals and all station control consoles, so that the traffic dispatching is finished, a dispatching command is issued, and the telephone blocking method starting driving is announced.

Further, the call is made to select all trains in the telephone blocking method section through the center console, and the selected driver's hand-held terminal mark (for example, driver ID number) and a parking operation instruction are transmitted to the back-end server.

In this example, the target station may be a station ahead of the current zone, or may be a target station selected according to other principles, and the target station and the train may be matched through a central control console.

In this example, each station only needs whether the number of the core entering/exiting vehicle is correct or not without checking information such as the running speed, and therefore, the station control console only needs the electronic block record number.

The train driver needs to check information such as the train number, the traveling speed, the target station, etc., and thus, an electronic ticket including the information needs to be transmitted to the driver.

(5) After the train drives into the target station, the electronic road ticket is marked to enter the station through the driver handheld terminal and then is uploaded to the background server.

And after receiving the electronic road ticket, the driver adopts a visual driving method, namely, the train can be stopped at any time and can move to a platform in front of the current driving interval to stop.

After the train is stopped stably, a driver can input the arrival information through the driver handheld terminal and upload the electronic road ticket to the background server through the driver handheld terminal, and the background server forwards the electronic road ticket to the train station control console.

(6) And the electronic blocking record number is uploaded to a background server after being marked by the target station control console.

In this example, after seeing that the train enters, the station attendant checks the train number, and if the train number is the same as the electronic blocking record number, the station control console can confirm that the train enters the station and upload the confirmation information to the background server.

(7) And the background server checks the received marked electronic road ticket and the marked electronic blocking record number, and recovers the electronic road ticket after confirming that the corresponding relation between the received marked electronic road ticket and the marked electronic blocking record number is correct.

The background report server receives the electronic road ticket which is uploaded by the driver handheld terminal and confirmed to enter the station and the electronic blocking record number which is uploaded by the target station control console and used for the train to enter the station, confirms the corresponding relation between the electronic road ticket and the electronic blocking record number, confirms that the train enters the station if the electronic road ticket and the electronic blocking record number correspond to each other, and updates a physical information database, such as train position information and section idle state information.

In this example, after all trains in each telephone block section complete the operation of starting block, the operation stage of telephone block is entered, specifically, under the condition that a signal chain fault occurs on the train route, the operation stage of telephone block is entered, and the urban rail transit train operation auxiliary system is used for executing:

(8) and the current station control console sends a target section telephone blocking request to the background server.

In this example, the target section may be specifically determined according to actual conditions for the trip dispatching, and the target station may also be a station specifically selected according to operation needs for the trip dispatching.

After the target station is determined, the current station attendant can apply for a telephone block to the target station, and specifically, send a telephone block request and a target station console code to the background server.

In this example, each station console is configured with a unique code.

(9) And the background server receives the telephone blocking request and forwards the telephone blocking request to a target station control console.

(10) And the target station control station confirms the blocking condition after receiving the telephone blocking request.

In this example, the occlusion conditions may be those customary in the art.

In this example, it is believed that an occlusion preparation may also be performed prior to occlusion, including hand-shaking switches, locking switches to prepare a route, or confirming that a route meets conditions, etc.

(11) And if the blocking condition meets the preset condition, the target station control console sends an electronic blocking record number to the background server.

(12) And the background server receives the electronic block record number and forwards the electronic block record number to a central console.

(13) And after receiving the electronic blocking record number, the central control station performs train collision detection, if the train collision detection is qualified, an electronic road ticket corresponding to the electronic blocking record number is generated, the electronic blocking record number is forwarded to the current station control station, and the electronic road ticket is sent to a driver handheld terminal.

(14) And after the electronic road ticket is confirmed through the driver handheld terminal, the train runs.

In this example, after the driver repeats the contents of the electronic ticket and confirms, the driver makes a bus to the target station according to the electronic ticket.

(15) And after the train drives into the target station, the electronic road ticket is confirmed by the driver handheld terminal and then uploaded to the background server.

(16) And the electronic blocking record number is uploaded to a background server after being marked by the target station control console.

(17) And the background server checks the received marked electronic road ticket and the marked electronic blocking record number, and recovers the electronic road ticket after confirming that the corresponding relation between the received marked electronic road ticket and the marked electronic blocking record number is correct.

In this example, after the step (17), the method may further include:

(17-1) the background server updating the physical information database according to the recovered electronic road ticket;

(17-2) the central control station updates the train operation diagram according to the updated physical information database.

In this example, the operations of steps (8) to (17) are cyclically performed, and the train is sequentially advanced in accordance with the block section.

In this example, during the telephone block operation, the real-time location of the train and the occupancy of the block section may be monitored simultaneously by the central control station and the station control station according to steps (17-1) and (17-2).

Further, the background processor can also monitor the interval occupancy and the train conflict.

In this example, after the traffic dispatching receives the report of the signal equipment fault recovery, the relevant station attendant confirms that the station signal equipment is recovered to be normal, and starts the telephone block cancellation process, specifically, in the case of a signal cascading fault occurring on the driving route, the urban rail transit driving assistance system is configured to perform:

(18) and the central console sends a cancellation instruction to the background server.

(19) And the background server receives the canceling instruction and forwards the canceling instruction to the station control console and the driver handheld terminal, so that the announcement of the call by canceling the telephone blocking method is completed.

In this example, if the train runs in the block section, the block is automatically released after the train reaches the target station. Specifically, the method comprises the following steps:

(20) after the train runs to a target station, the electronic road ticket is uploaded to a background server through a driver handheld terminal;

(21) the electronic blocking record number is uploaded to a background server after being marked by the target station control console to enter the station;

(22) the background server checks the received marked electronic road ticket and the marked electronic blocking record number, and recovers the electronic road ticket after confirming that the corresponding relation between the two is correct;

(22) the normal operation mode is started.

And after receiving an instruction for starting normal operation simulation through a driver handheld terminal, a corresponding train driver restores to the normal driving mode to operate according to signal display.
