Description

TECHNICAL FIELD

[0001] The present application relates to a kind of reconnection mode automatic identification method, system and rail transit equipment, belong to railway transportation field. BACKGROUND

[0002] Currently, when reconnection between locomotives or between track engineering vehicles, communication is mainly through WTB (Wire Train Bus) bus. In actual application, a flat car is connected in the middle of some engineering vehicles, so hard-wire reconnection mode needs to be used. WTB bus is a bus technology used for data communication between trains, which works based on twisted shielded wire, and the transmission rate is usually 1 Mbit / s. WTB reconnection mode (i.e., twisted wire train bus reconnection mode) refers to connecting multiple trains or locomotives through WTB bus to realize data communication and control synchronization between trains or locomotives. WTB reconnection mode is commonly used in high-speed motor trains and heavy-load trains, which can efficiently transmit a large amount of data and ensure coordinated operation between trains. Hard-wire reconnection mode refers to directly connecting the control systems of trains or locomotives through physical cables (such as hard-wire) to transmit signals and instructions. Hard-wire reconnection mode is usually used in traditional railway systems and has the characteristics of simple connection and high reliability, and is also used in some occasions with high requirements for real-time performance and reliability, such as marshalling operation of subway trains.

[0003] When reconnection control between track engineering vehicles or locomotives, WTB reconnection mode is usually used by default. When switching to hard-wire reconnection mode, it needs to be set through HMI (Human Machine Interface). When switching back to WTB reconnection mode, it also needs to be set on HMI. Since the conversion of reconnection mode affects train safety, the operation of conversion needs to be performed on the HMI maintenance interface. When logging in to the HMI maintenance interface, a password needs to be entered, which is a relatively cumbersome process. There is also a situation where the driver forgets to set the reconnection mode, resulting in unsuccessful reconnection communication. Therefore, there is an urgent need to provide a technical solution for automatic identification of reconnection mode to effectively solve the above problems. SUMMARY

[0035] Embodiment 1

[0036] Figure 1 is a reconnection mode automatic identification flowchart of the rail transit equipment of the embodiment 1 of the present application. Figure 1 The provided flow is a reconnection mode automatic identification flow when the default reconnection mode of the rail transit equipment is the WTB reconnection mode. The specific implementation process includes:

[0037] S0, if the current reconnection mode of the rail transit equipment is the WTB reconnection mode, step S1 is entered; the rail transit equipment includes a master vehicle and a slave vehicle;

[0038] S1, the master vehicle's CCU receives the slave vehicle's CCU life signal through WTB communication, judges whether the slave vehicle's CCU life signal value jumps or not, if yes, enters step S2; if no, enters step S3; the jump includes sequential increase within the value range and revaluating 0 when reaching the maximum value within the value range;

[0039] S2, the slave vehicle's CCU receives the master vehicle's CCU life signal through WTB communication, judges whether the master vehicle's CCU life signal value jumps or not, if yes, determines that the WTB reconnection mode, the rail transit equipment controls the vehicle in the WTB reconnection mode, and prompts in the HMI, enters step S0; if no, enters step S3;

[0040] According to the rail transit communication network protocol, the range of CCU life signal value can be set as (0, 65535). Detecting whether the CCU life signal value jumps or not, that is, detecting whether the CCU life signal value sequentially increases within the range of (0, 65535) or revaluates 0 when greater than 65535, if yes, defaults to the WTB reconnection mode, controls the vehicle in the WTB reconnection mode, and prompts in the HMI.

[0041] S3, the master vehicle periodically sends the first control instruction through the special hard-wire channel, judges whether the rail transit equipment is in the reconnection mode allowing conversion state or not, if yes, initializes the integer i as 0, when the slave vehicle receives the first control instruction in each second time interval, accumulates the count of the first control instruction, that is, the value of i is added by 1, enters step S4;

[0042] When the current reconnection mode of the rail transit equipment is the WTB reconnection mode, the vehicle cannot receive the other vehicle's jump CCU life signal within the first time interval (2 seconds in this embodiment), even if the other vehicle's instruction is received through the hard-wire channel, only when the rail transit equipment is in the reconnection mode allowing conversion state, the hard-wire reconnection mode is allowed to be switched; when the vehicle is the master vehicle, the other vehicle is the slave vehicle; when the vehicle is the slave vehicle, the other vehicle is the master vehicle; the reconnection mode allowing conversion state of the rail transit equipment includes: locomotive stationary, controller zero position, pantograph down and main break open.

[0043] S4, judges whether i jumps or not, if yes, determines that the slave vehicle is in the hard-wire reconnection mode, and periodically returns the second control instruction to the master vehicle, enters step S5; if no, determines that it is not the WTB and hard-wire reconnection mode, and the rail transit equipment runs alone;

[0044] S5, initializes the integer j as 0, when the master vehicle receives the second control instruction in each third time interval, accumulates the count of the second control instruction, that is, the value of j is added by 1, enters step S6;

[0045] S6, determining whether j is jumping, if yes, determining that the host vehicle is in hard-wire reconnection mode; if no, determining that the host vehicle is in non-WTB non-hard-wire reconnection mode, and the rail transit device is running in single mode.

[0046] The reconnection mode automatic recognition method provided in the embodiment is used when the rail transit device defaults to use WTB reconnection mode. When the WTB reconnection mode does not meet the actual reconnection requirement of the train, the corresponding reconnection mode is automatically determined according to the automatic recognition method provided in the embodiment.

[0047] In the embodiment, the number of special hard-wire channels used to identify whether the hard-wire transmission is normal is only one, while in the normal case, two special hard-wire channels are needed between the host vehicle and the slave vehicle to identify whether the hard-wire transmission is normal. Since the reconnection socket cable is limited, under the condition that the number of hard-wire channels n is limited, the embodiment can realize that more hard-wire channels are used for hard-wire code transmission, so that more hard-wire control instructions can be transmitted, that is, the remaining n-1 hard-wire channels are used to form hard-wire codes for control instruction transmission, and the n-1 hard-wire channels can form 2 n-1 -1 code instructions; while in the normal case, the remaining hard-wire channels are n-2, which can form 2 n-2 -1 code instructions; one more hard-wire channel can increase the number of hard-wire code instructions transmitted by about 2 times. Wherein, n is determined by the number of code instructions.

[0048] In the embodiment, one hard-wire channel is used to transmit two different instructions sent by the host vehicle and the slave vehicle, and the specific implementation process is as follows:

[0049] Through one special hard-wire channel in the reconnection socket, the CCU of the host vehicle periodically (2 seconds in the embodiment) sends one 200ms pulse high level, and the corresponding control instruction code can be regarded as “1”. When the slave vehicle receives the control instruction code “1” sent by the host vehicle in each second time interval (2 seconds in the embodiment), the instruction count is accumulated, and two 200ms pulse high levels are periodically (2 seconds in the embodiment) transmitted back, the high level instruction interval is 200ms, and the transmitted control instruction code can be regarded as “101”. When the host vehicle receives the control instruction code “101” transmitted back by the slave vehicle in each third time interval (2 seconds in the embodiment), the instruction count is also accumulated. When the host vehicle and the slave vehicle each determine that the instruction count is jumping (in the embodiment, when the instruction count reaches 65535, it starts from 0), the hard-wire channel communication of the host vehicle and the slave vehicle is normal, it is determined to use hard-wire reconnection mode, and the host vehicle is controlled in the hard-wire reconnection mode.

[0050] In the embodiment, if the other vehicle CCU life signal value is not received by WTB communication and the other vehicle instruction is not received by the hard-wire channel, it is determined that the non-WTB non-hard-wire reconnection mode, i.e., the rail transit equipment is in a single machine operation state.

[0051] Embodiment 2

[0052] Figure 2 The flowchart for automatically identifying the reconnection mode of the rail transit equipment in Embodiment 2 of the application is shown in FIG. 2. Figure 2 The provided flowchart is for automatically identifying the reconnection mode of the rail transit equipment when the default reconnection mode of the rail transit equipment is the hard-wire reconnection mode. The specific implementation process includes:

[0053] S0, if the current reconnection mode of the rail transit equipment is the hard-wire reconnection mode, go to step S7;

[0054] S7, the master vehicle periodically sends the first control instruction through the special hard-wire channel, initializes i as 0, and each time the slave vehicle receives the first control instruction in the second time interval, adds the count of the first control instruction, i.e., adds 1 to the value of i, and goes to step S8;

[0055] S8, judges whether i jumps or not, if yes, determines that the slave vehicle is in the hard-wire reconnection mode, and periodically returns the second control instruction to the master vehicle through the special hard-wire channel, and goes to step S9; if no, goes to step S10;

[0056] S9, initializes j as 0, each time the master vehicle receives the second control instruction in the third time interval, adds the count of the second control instruction, i.e., adds 1 to the value of j, judges whether j jumps or not, if yes, determines that the master vehicle is in the hard-wire reconnection mode; if no, goes to step S10;

[0057] S10, judges whether the rail transit equipment is in a reconnection mode conversion allowed state or not, if yes, goes to step S11;

[0058] When the reconnection mode of the rail transit equipment is the hard-wire reconnection mode, the hard-wire instruction count (i and / or j) of the vehicle does not jump, even if the other vehicle CCU life signal value is received by WTB communication, only when the rail transit equipment is in the reconnection mode conversion allowed state, the WTB reconnection mode is allowed to be switched. The jump includes the sequential increase in the value range and the re-take value as 0 when reaching the maximum value in the value range; when the vehicle is the master vehicle, the other vehicle is the slave vehicle; when the vehicle is the slave vehicle, the other vehicle is the master vehicle; the reconnection mode conversion allowed state of the rail transit equipment includes: the locomotive is stationary, the controller is in the zero position, the pantograph is lowered, and the main switch is open.

[0059] S11, the CCU of the slave vehicle receives the CCU life signal of the master vehicle through WTB communication, and judges whether the CCU life signal value of the slave vehicle jumps or not, if yes, step S12 is entered; if no, it is determined that the WTB hard-wire reconnection mode is not used, and the rail transit equipment is operated independently;

[0060] S12, the CCU of the slave vehicle receives the CCU life signal of the master vehicle through WTB communication, and judges whether the CCU life signal value of the master vehicle jumps or not, if yes, it is determined that the rail transit equipment is in the WTB reconnection mode, the rail transit equipment is controlled in the WTB reconnection mode, and a prompt is given in the HMI, and step S0 is entered; if no, it is determined that the WTB hard-wire reconnection mode is not used, and the rail transit equipment is operated independently.

[0061] According to the rail transit communication network protocol, the range of the CCU life signal value can be set as (0, 65535). It is detected whether the CCU life signal value jumps or not, that is, whether the CCU life signal value sequentially increases within the range of (0, 65535) or is reset to 0 when greater than 65535, if yes, it is determined that the WTB reconnection mode is used, the rail transit equipment is controlled in the WTB reconnection mode, and a prompt is given in the HMI.

[0062] The reconnection mode automatic recognition method provided in the embodiment is used when the rail transit equipment defaults to use the hard-wire reconnection mode. When the hard-wire reconnection mode does not meet the actual reconnection requirements of the train, the automatic recognition method provided in the embodiment is used to automatically determine the corresponding reconnection mode.

[0063] In the embodiment, the number of special hard-wire channels used to identify whether the hard-wire transmission is normal is only one, while in the normal case, two special hard-wire channels are needed between the master vehicle and the slave vehicle to identify whether the hard-wire transmission is normal. Since the number of reconnection socket cables is limited, under the condition that the number of hard-wire channels n is limited, the embodiment can realize that more hard-wire channels are used for hard-wire code transmission, so that more hard-wire control instructions can be transmitted, that is, the remaining n-1 hard-wire channels are used to form a hard-wire code for control instruction transmission, and the n-1 hard-wire channels can form 2 n-1 -1 code instructions; while in the normal case, the remaining n-2 hard-wire channels can form 2 n-2 -1 code instructions; one more hard-wire channel can increase the number of hard-wire code instructions transmitted by about 2 times. Wherein, n is determined by the number of code instructions.

[0064] In the embodiment, one hard-wire channel is used to transmit two different instructions sent by the master vehicle and the slave vehicle, respectively, and the specific implementation process is as follows:

[0065] The master vehicle sends a 200ms pulse high level periodically (2 seconds in this embodiment) through a special hard-wire channel in the socket, and the corresponding control instruction code can be regarded as "1". After the slave vehicle receives the control instruction code "1" sent by the master vehicle periodically (2 seconds in this embodiment) in the second time interval (2 seconds in this embodiment), the instruction count is accumulated, and two 200ms pulse high levels are returned periodically (2 seconds in this embodiment), and the high level instruction interval is 200ms, and the returned control instruction code can be regarded as "101". After the master vehicle receives the control instruction code "101" returned by the slave vehicle periodically (2 seconds in this embodiment) in the third time interval (2 seconds in this embodiment), the instruction count is also accumulated. When the master vehicle and the slave vehicle each determine that the instruction count is jumping (in this embodiment, when the instruction count is 65535, it starts from 0), the hard-wire channel communication of the master vehicle and the slave vehicle is normal, the hard-wire reconnection mode is determined, and the vehicle is controlled in the hard-wire reconnection mode.

[0066] In this embodiment, if the CCU life signal value of the other vehicle cannot be received through the WTB communication, and the instruction of the other vehicle cannot be received through the hard-wire channel, it is determined that it is a non-WTB non-hard-wire reconnection mode, that is, the rail transit equipment is in a single machine operation state.
