Description

Technical Field

[0001] The present invention belongs to the technical field of train phase-shifting, and in particular relates to a phase-shifting method, system and vehicle-mounted equipment of a fully automatic driving system. Background Art

[0002] The phase separation zone is the non-powered section of the electrified railway. It is usually located near the substation of the AC electrified line, the separation of the power supply areas of two AC substations, or the junction of AC and DC power supply. When the train passes through the phase separation zone, the main circuit breaker needs to be opened and closed.

[0003] Trains generally have multiple ways of over-phase, including on-board equipment over-phase, magnetic steel over-phase, and manual over-phase. The on-board equipment over-phase method is generally used. There is a problem with the automatic over-phase of on-board equipment. The on-board equipment outputs a main circuit breaker disconnect command to the train before entering the phase-splitting area, and outputs a main circuit breaker closing command to the train after leaving the phase-splitting area. No feedback from the train is collected, and no closed-loop inspection is performed. At the same time, in on-site operations, automatic over-phase failure of on-board equipment occasionally occurs. Therefore, during the automatic over-phase process of the on-board equipment, before entering the phase-splitting area, if the driver finds that the main circuit breaker is not disconnected, he will manually press the main circuit breaker disconnect button on the driving console to manually disconnect the main circuit breaker; after leaving the phase-splitting area, if the driver finds that the main circuit breaker is not closed, he will manually press the main circuit breaker closing button on the driving console to manually close the main circuit breaker.

[0004] However, in a fully automatic operation system, there is usually no driver on duty in the cab. During the process of the on-board equipment automatically passing the phase-separation zone, before the phase-separation zone, the on-board equipment outputs a main disconnection command to the train. If the main disconnection command is not executed successfully, and there is no driver to monitor and press the "main disconnection" button on the cab in time to manually pass the phase-separation zone, it will bring safety hazards.

DETAILED DESCRIPTION

[0023] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be combined with the present invention to A method for over-phase separation of a fully automatic driving system comprises the following steps: S1. When the train is at a first distance from the phase separation zone, the on-board equipment receives the phase separation zone information sent by the ground transponder and sends an on-board equipment over-phase selection command to the train; S2. When the train is at a second distance from the phase separation zone, the on-board equipment sends an on-board equipment disconnection command to the train, so that the train performs the on-board equipment disconnection action according to the on-board equipment disconnection command; S3, when the train is at a third distance from the phase separation area, the on-board equipment determines whether the on-board equipment successfully disconnects the main disconnection status information sent by the train; S31, if yes, the train passes through the phase separation area based on the main disconnection action of the on-board equipment; S32. If not, the on-board equipment stops sending the on-board equipment over-phase selection command to the train, and sends the magnetic steel over-phase selection command to the train. The magnetic steel over-phase selection command is used when the train is at the fourth distance from the phase separation area. The magnetic signal receiving unit on the train receives the first magnetic steel signal from the ground, executes the magnetic steel main breaking action according to the first magnetic steel signal, and passes through the phase separation area.

[0024] Specifically, when the on-board equipment does not receive the on-board equipment successful main disconnection status information sent by the train, it means that the on-board equipment main disconnection action fails, and then the on-board equipment fails in excessive phase separation.

[0025] In step S1, the onboard equipment (ATO+ATP) establishes wireless communication with the ground radio block center through the train's train-to-ground wireless communication system, and then obtains the phase zone information, or obtains the phase zone information from the ground transponder through electromagnetic induction.

[0026] The magnetic steel transition phase includes four magnetic steels, G1, G2, G3 and G4, among which G1 is the transition phase pre-announcement disconnection, G2 is the transition phase forced disconnection, G3 is the transition phase pre-announcement closing, and G4 is the transition phase forced closing. A magnetic signal receiving unit is installed on the train, which senses the magnetic steel through the magnetic signal receiving unit, thereby realizing the magnetic steel transition phase.

[0027] It should be further explained that the first distance, the second distance, the third distance, the fourth distance, the fifth distance, the sixth distance, the seventh distance, etc. are all preset values. In actual applications, these distances can be flexibly adjusted according to the specific length of the phase separation zone, the line slope, the train speed and other operational requirements. For example, for a longer phase separation zone, the interval between the first distance and the second distance can be appropriately increased to ensure that there is enough time to complete the necessary operations; and for a shorter phase separation zone, these distances can be shortened to ensure the timeliness and accuracy of the operation.

[0028] As a preferred embodiment of the present disclosure, after the train passes through the phase-splitting area based on the main breaking action of the on-board equipment, it also includes: S4, when the train passes through the phase-splitting area and is at the fifth distance from the phase-splitting area, the on-board equipment sends an on-board equipment main closing and breaking command to the train, so that the train executes the on-board equipment main closing and breaking action according to the on-board equipment main closing and breaking command; when the train passes through the phase-splitting area and is at the sixth distance from the phase-splitting area, the on-board equipment stops sending the on-board equipment over-phase selection command to the train.

[0029] As a preferred embodiment of the present disclosure, S5, a magnetic signal receiving unit on the train receives a first magnetic steel signal from the ground, performs a magnetic steel main breaking action according to the first magnetic steel signal, and after passing through the phase separation zone, it also includes: when the train passes through the phase separation zone and is at the seventh distance from the phase separation zone, the magnetic signal receiving unit on the train receives a second magnetic steel signal from the ground, and performs a magnetic steel main breaking action according to the second magnetic steel signal.

[0030] For example, refer to Figure 2 As shown in the figure, the on-board equipment over-phase disconnection main disconnection successful process: when the train passes Point (first distance), after the onboard equipment receives the phase separation zone information from the ground transponder, it outputs the onboard equipment over-phase selection command to the train, so that the train obtains the onboard equipment over-phase selection command sent by the onboard equipment, and determines the onboard equipment over-phase based on the onboard equipment over-phase selection command. Point (the second distance, i.e. the remaining time of the train from the forecast break G1 is seconds), the on-board equipment outputs the main disconnection command to the train and starts to check the train feedback. The train receives the main disconnection command from the on-board equipment, immediately executes the main disconnection action, and feeds back the main disconnection status information to the on-board equipment. Point (third distance, from Start at 12:00, train running seconds, the position reached is point), the on-board equipment receives the main disconnection success information from the train, and the on-board equipment considers that the main disconnection is successful. After the front of the train passes the end of the phase-splitting area (passes the phase-splitting area), the on-board equipment calculates the running distance of the front of the train from the end of the phase-splitting area in real time. When the running distance of the front of the train from the end of the phase-splitting area exceeds 130m (the fifth distance), the on-board equipment outputs the main disconnection command to the train, and the train immediately executes the main disconnection command. When the running distance of the front of the train from the end of the phase-splitting area exceeds 1000m (the sixth distance), the on-board equipment stops outputting the on-board equipment over-phase selection command to the train. For further information, refer to Figure 4 As shown in the figure, the successful model of the fully automatic vehicle equipment over-phase is divided into the coasting stage, the traction delay stage and the acceleration stage. The vehicle equipment is advanced before the predicted break point G1. The main disconnection command is output at the time, and the train begins to pass the phase separation area in a coasting manner. When the train head passes the phase separation area 130m away, the main disconnection command is output. The on-board equipment outputs the traction command to the train. After the equivalent traction delay time, the train accelerates and returns to normal speed. It can be seen that the running distance in the coasting stage includes t 1 Time running distance, distance from the predicted break G1 point to the starting point of the phase separation zone (255m), length of the phase separation zone and 130m after the end point of the phase separation zone.

[0031] For example, refer to Figure 3 As shown in the figure, the on-board equipment fails due to excessive phase disconnection: when the train passes Point (first distance), after the onboard equipment receives the phase separation zone information from the ground transponder, it outputs the onboard equipment over-phase selection command to the train, so that the train obtains the onboard equipment over-phase selection command sent by the onboard equipment, and determines the onboard equipment over-phase based on the onboard equipment over-phase selection command. Point (the second distance, i.e. the remaining time of the train from the forecast break G1 is seconds), the on-board equipment outputs the main disconnection command to the train and starts to check the train feedback. The train receives the main disconnection command from the on-board equipment, immediately executes the main disconnection action, and feeds back the main disconnection status information to the on-board equipment. Point (third distance, from Start at 12:00, train running seconds, the position reached is When the train passes through the onboard equipment, the onboard equipment cannot receive the main disconnection success information from the train, and the onboard equipment considers that the main disconnection has failed, and immediately outputs the train magnetic steel over-phase selection signal to the train, and stops the automatic over-phase process of the onboard equipment. Point or At the fourth distance, the magnetic signal receiving unit receives the magnetic steel signal on the ground and makes a master cut based on the magnetic steel information. Point or At point (the seventh distance), the magnetic signal receiving unit receives the magnetic steel signal on the ground and makes a decision based on the magnetic steel information. Figure 5 As shown in the figure, the over-phase failure model of fully automatic vehicle equipment is divided into the coasting stage, the traction delay stage and the acceleration stage. In the fully automatic driving system, the vehicle equipment is advanced before the predicted break point G1. The time outputs the main disconnection command and starts to coast through the phase-splitting area. The on-board equipment fails to disconnect the main disconnection, and the train switches to magnetic steel passing the phase before the predicted disconnection point G1. When passing the predicted disconnection point G1, the magnetic steel information is received and the main disconnection is successfully disconnected, and the train continues to coast through the phase-splitting area. When the front of the train passes the predicted closing point G3 or the forced closing point G4, the main closing command is output. The on-board equipment outputs a traction command to the train. After an equivalent traction delay time, the train accelerates and returns to normal speed. It can be seen that the running distance in the coasting stage includes t 1 Time running distance, distance from the predicted break point G1 to the starting point of the phase separation zone (255m), length of the phase separation zone, and distance from the end point of the phase separation zone to the forced closing point G4 (255m).

[0032] By combining the on-board equipment over-phase and the train magnetic steel over-phase, it is possible to immediately switch to the over-phase mode based on the magnetic steel signal when the on-board equipment over-phase fails, ensuring that the train can safely pass through the phase separation area under any circumstances. This solves the problem of relying solely on a single on-board equipment for automatic over-phase, which may lead to unexpected situations once a failure occurs and there is no human intervention.
