Description

Technical Field

[0001] The present invention relates to the technical field of urban rail transit, and in particular to a train operation control method, device, equipment, storage medium and program product. Background Art

[0002] In urban rail transit, the Communication-Based Train Control System (CBTC) is the main way to control train operation. It is based on wireless communication technology and can control the operation of trains in real time and accurately. Through wireless communication between the train and the ground, the system can continuously track key information such as the position and speed of the train, dynamically adjust the running speed and interval distance of the train, thereby effectively avoiding safety accidents such as train collisions, which plays a vital role in ensuring the safe operation of trains.

[0003] In the prior art, when a zone controller (ZC) fails or a problem occurs in the train-to-ground wireless communication, the system will first convert the train operation mode from CBTC to RM mode, and then to Intermittent Train Control (ITC) level.

[0004] However, RM mode is a restricted manual mode in which the train speed is limited to a low level. Moreover, the train must run at this low speed until it encounters an active balise to upgrade the mode. Since the train runs at such a low speed throughout the entire section, which is a significant drop compared to the normal operating speed, the train cannot run according to the normal schedule, resulting in serious delays, which has a great negative impact on the normal operation order and transportation efficiency of rail transit.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them.

[0022] It should be noted that, in this article, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

In addition, it should be pointed out that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in reverse order according to the functions involved, for example, the described method may be performed in an order different from that described, and various steps may also be added, omitted, or combined. In addition, the features described with reference to certain examples may be combined in other examples.

[0023] In order to facilitate a clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and order of execution.

[0024] The embodiments of the present application describe some exemplary embodiments for the purpose of explanation. It should be understood that the present application can be implemented in other ways that are not specifically shown in the drawings.

[0025] like Figure 1 As shown, the embodiment of the present application provides a train operation control method, which can be applied to a train operation control device. The train operation control method may include S101-S103: S101. In the event of a failure in the train automatic control system, the train operation control device sends a signal status request message to the computer interlocking device and sends the front and rear vehicle position query information to the secondary radar host.

[0026] Optionally, the fault type of the train automatic control system includes: regional controller failure or train-to-ground wireless communication failure.

[0027] Optionally, before sending signal status application information to the computer interlocking device and sending front and rear vehicle position query information to the secondary radar host, the train operation control device can be connected to the secondary radar host, and the secondary radar host is connected to the ground base station through the vehicle-mounted radar.

[0028] Specifically, in rail transit systems, such as subways and urban light rails, the lines are divided into multiple control areas, and each area is monitored by a corresponding regional controller. The regional controller is an important device in CBTC, which is mainly responsible for managing and controlling the operation of trains in the area under its jurisdiction. When CBTC is operating normally, the regional controller plays a key role. The regional controller usually communicates with trackside equipment (such as transponders, axle counters, etc.) and on-board equipment (such as automatic train protection systems, etc.). It receives information such as train position and track occupancy from trackside equipment, and calculates movement authorization based on this information. Movement authorization refers to the range within which the train is allowed to operate safely at the current position. Under normal circumstances, in order to maintain a safe interval, the end point of the movement authorization can be calculated to the rear of the train in front. By calculating the movement authorization to the rear of the train in front, the following vehicle knows where it can travel without endangering driving safety, so that it can reasonably control the speed and move along the authorized range.

[0029] However, the process of the train receiving the movement authorization calculated by the regional controller depends on the normal operation of the communication system. Once the communication link between the train and the regional controller fails, or the regional controller itself has an abnormality, it is difficult for the train to quickly and accurately obtain the movement authorization information. When this happens, the train will enter the degraded mode to ensure safe operation. Compared with the precise control based on movement authorization in the normal mode of CBTC, the operation efficiency of the train in the degraded mode will be reduced.

[0030] When a train cannot receive the movement authorization calculated by the regional controller and is degraded, the train needs to find other ways to obtain information about the line ahead to ensure safe operation. Computer-based Interlocking (CI) equipment is mainly responsible for controlling and supervising the operating status of trackside equipment such as turnouts and signal machines in the station. At this time, the train will actively call the CI equipment and request the status information of the signal machine ahead to clarify the display status of the signal machine. At the same time, the train sends the position query information of the front and rear vehicles to the secondary radar host in order to grasp the position details of the front and rear vehicles.

[0031] It should be noted that the ground secondary radar host is an important part of the entire train positioning system. The vehicle-mounted radar is connected to the ground base station, and this connection method forms a network that can accurately monitor the train position. The ground secondary radar host is like a "train location information center". Through interaction with the vehicle-mounted radar, it collects and manages the location information of all trains on the line. Its working process is similar to the radar system in air traffic control. The vehicle-mounted radar transmits a signal to the ground base station, and the ground base station receives the signal and transmits it to the ground secondary radar host. At the same time, the ground secondary radar host can also send instructions or location-related information to the vehicle-mounted system.

[0032] S102, the train operation control device receives the signal status information sent by the computer interlocking device and the front and rear vehicle position information sent by the secondary radar host.

[0033] S103: The train operation control device autonomously calculates the movement authorization according to the signal status information and the position information of the front and rear vehicles.

[0034] Optionally, the signal status information includes information such as color (red, green, yellow, etc.) and type (entering, exiting, section passing, etc.). For example, when the CI device informs the train that the signal ahead is green, it means that the train can travel at the specified speed; if the signal is yellow, the train needs to consider slowing down, and when calculating the movement authorization, the deceleration area and distance must be taken into consideration. If the signal is red, the train must stop, in which case the end point of the movement authorization may be just before the signal.

[0035] Optionally, the position information of the preceding vehicle provided by the secondary radar host allows the train to clearly understand the specific position of the preceding vehicle. This is essential for determining the safe interval between trains. For example, by knowing the precise position of the rear of the preceding vehicle through radar, the train can use this as a reference to calculate the position it can safely drive to, thereby determining the end point of the movement authorization.

[0036] Alternatively, if Figure 2 As shown, if there is no vehicle in the same route, the mobile authorization is calculated autonomously to the first signal ahead according to the signal status information and the position information of the front and rear vehicles; Figure 3 As shown, if there is a vehicle in the same route, the movement authorization is autonomously calculated to the rear of the front vehicle based on the signal status information and the position information of the front and rear vehicles.

[0037] It should be noted that when there are other vehicles on the same route, the train will automatically calculate the movement authorization to the rear of the preceding vehicle. This is based on the consideration of safety interval. In order to prevent rear-end collisions, the train needs to ensure that its driving range will not collide with the preceding vehicle. Calculating the movement authorization to the rear of the preceding vehicle can ensure that the train runs within a safe range.

[0038] For example, the train will consider its own braking performance, current speed, the speed of the preceding vehicle (if available), and other factors, combined with the signal status, to determine a movement authorization range that allows it to safely travel to the rear of the preceding vehicle. This process requires the train's onboard system to comprehensively analyze various information and accurately calculate the range within which the train is allowed to operate under the current circumstances.

[0039] In the embodiment of the present application, the signal status information sent by the computer interlocking device and the front and rear vehicle position information sent by the secondary radar host can be obtained, and the movement authorization can be autonomously calculated based on the signal status information and the front and rear vehicle position information. Since the signal status information and the front and rear vehicle position information can be determined at any time, the train does not need to run at a low speed, which can ensure the normal operation order and transportation efficiency of rail transit and avoid delays.

[0040] The above mainly introduces the solution provided by the embodiment of the present application from the perspective of the method.

Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution.

Since the signal status information and the front and rear vehicle position information can be determined at any time, the train does not need to run at a low speed, which can ensure the normal operation order and transportation efficiency of rail transit and avoid delays.
