Description

Technical Field

[0001] The present invention relates to the technical field of rail transit train operation monitoring systems, and more particularly to a synchronous control method for a rail vehicle system and a rail vehicle system. Background Art

[0002] The train operation monitoring device is the most important train operation safety system and an important part of the railway transportation safety guarantee system. The train operation monitoring device aims to ensure operation safety and performs real-time control of the train by monitoring the running speed. While achieving safe speed control, this device collects and records various locomotive operation status information related to the safe operation of the train, promoting the automation of locomotive operation management. With the development of transportation demands, the train operation monitoring device has gradually become the on-train operation information center of the train, providing a basis for various safety monitoring and operation information transmission.

[0003] The train operation monitoring device mainly consists of a monitoring host and a man-machine interaction unit. The man-machine interaction unit is the most important man-machine interaction method of the train operation monitoring device. Both the monitoring host and the man-machine interaction unit directly obtain the working power supply from the locomotive terminal. To ensure synchronous power-on and power-off of the monitoring host and the man-machine interaction unit, the monitoring host needs to control the power-on of the man-machine interaction unit.

[0004] Currently, the above function is implemented by using a power-on control signal provided by the monitoring host (hereinafter referred to as the existing solution). After the monitoring host works, it sets the power-on control signal to high. The power supply module of the man-machine interaction unit collects the power-on control signal. When the switch value is high, the power supply module works; when the switch value is low, the power supply module does not work. This solution has certain defects, resulting in frequent abnormalities of the power-on control signal, which in turn leads to failures of the man-machine interaction unit, and the driver cannot control the train, seriously affecting the train operation safety. Summary of the Invention

[0005] In view of this, to solve the above technical problems, the purpose of the present invention is to provide a synchronous control method for a rail vehicle system and a rail vehicle system to solve the problems raised in the above background art.

[0006] In a first aspect, the present invention provides a synchronous control method within a rail vehicle system. The rail vehicle system includes a main control unit and a synchronous unit, and the synchronous unit is controlled by the main control unit. The method is applied to the synchronous unit and includes: receiving the level state of the power-on control signal sent by the main control unit, and synchronously confirming the running state of the communication link of the main control unit; when any one of the power-on control signal and the running state of the communication link meets the working condition, maintaining the state of the synchronous unit as the working state.

[0007] In some specific implementation manners, the method further includes: when the power-on control signal and the operating state of the communication link do not satisfy the working conditions simultaneously, the operating state of the synchronization unit changes from the working state to the off state.

[0008] In some specific implementation manners, that the power-on control signal satisfies the working conditions includes: the level state of the power-on control signal is high level.

[0009] In some specific implementation manners, that the power-on control signal does not satisfy the working conditions includes: the level state of the power-on control signal is low level.

[0010] In some specific implementation manners, whether the operating state of the communication link satisfies the working conditions is determined by whether the active unit sends a communication signal to the synchronization unit.

[0011] In a second aspect, a rail vehicle system is provided, including a main control unit and a synchronization unit. The synchronization unit is controlled by the main control unit. Both the main control unit and the synchronization unit are provided with a power supply module and an information processing module. The power supply module is used to generate and receive a power-on control signal. The information processing module is used for establishing a communication link. A processing module is further provided in the synchronization unit. The processing module is electrically connected to the power supply module and the information processing module in the synchronization unit, and is used to receive the power-on control signal and determine the level state of the power-on control signal, and monitor the communication link, and execute the method according to any one of the above.

[0012] In some specific implementation manners, the processing module determines whether the current operating state of the communication link satisfies the working conditions according to the working state of the information processing module.

[0013] In some specific implementation manners, when the processing module receives an internal power-on control signal sent by the information processing module in the synchronization unit, and the level state of the internal power-on control signal is high level, it is determined that the current operating state of the communication link satisfies the working conditions.

[0014] In some specific implementation manners, when the processing module does not receive an internal power-on control signal sent by the information processing module in the synchronization unit, and the level state of the internal power-on control signal is low level, it is determined that the current operating state of the communication link does not satisfy the working conditions.

[0015] In some specific implementation manners, the determination of the level state of the internal power-on control signal is determined by whether the information processing module in the main control unit sends a communication signal to the synchronization unit. When the communication signal is sent, an internal power-on control signal with a high level is generated. When the communication signal is not sent, an internal power-on control signal with a low level is generated.

[0016] The embodiments of the present invention bring the following beneficial effects:

[0017] The embodiments of the present invention provide a method for synchronously controlling a rail vehicle machine system and a rail vehicle machine system. By setting two working trigger mechanisms for the synchronization unit, the operation of the synchronization unit is changed from being activated by a single control signal in the prior art to being activated by both a control signal and synchronous communication information. Fundamentally, the problem of the black screen failure of the human-machine interaction unit caused by abnormal power-on control signals during the operation of the existing solution is solved. The problem of unstable hardware transmission of key signals caused by connector material problems is solved. The problem of short-circuit of the power-on control signal caused by a single module failure during operation is solved, creating conditions for timely and effective handling of faults, greatly improving the reliability of the system, and effectively ensuring the operation safety of trains and railway lines.

[0029] The embodiment of the present application provides a method for synchronous control within a rail vehicle machine system and a rail vehicle machine system. For the rail vehicle machine system, it includes a main control unit and a synchronization unit, where the synchronization unit is controlled by the main control unit, and the synchronization unit generates changes in the working state based on the active control of the main control unit.

[0030] Among them, the rail vehicle machine system in this embodiment includes any localization system used in a rail train and having the functions of issuing main control commands and changing synchronization states. However, for the purpose of specifically illustrating the technical solution, the operation monitoring device is used as a representative of this system in this embodiment for description.

[0031] Refer toFigure 1 Figure 1 is a schematic diagram of the architecture of an on-vehicle machine system, especially the operation monitoring device, in the prior art, mainly including a monitoring host and a man-machine interface unit. The monitoring host is used to obtain data during the operation of a rail transit train and transmit this data to the man-machine interface unit for vehicle operators to observe the data. Power supply modules and information processing units are provided in both the monitoring host and the man-machine interface unit, and the work of the monitoring host and the man-machine interface unit is synchronous. That is, when the monitoring host starts its operation, the man-machine interface unit operates synchronously. Therefore, in order to ensure the consistency of their work, in the prior art, the man-machine interface unit generally adjusts the power-on and power-off synchronously by obtaining the power-on state and power-off state of the monitoring host.

[0032] However, there are certain defects in the above-mentioned prior solution, which lead to frequent abnormal power-on control, and then lead to faults in the man-machine interaction unit, thus making it impossible to control the train, seriously affecting the train operation safety. The reasons for the defects include but are not limited to the following situations: (1) The connector between the monitoring host and the man-machine interaction unit fails, resulting in unstable transmission of the power-on control signal; (2) The power-on control signal circuit part of the power supply module of the monitoring host is short-circuited, resulting in short-circuit of the power-on control signal and no output; (3) There are interference signals during cable transmission, resulting in unstable power-on control signal; (4) The power-on control signal is abnormal during operation, and the man-machine interaction unit goes black, resulting in an emergency stop of the locomotive, seriously affecting the safety of the railway line.

[0033] Therefore, in order to solve the problems in the above-mentioned prior art, in this embodiment, a control method is provided to solve the technical problems existing in the above-mentioned train operation monitoring device by means of redundant power-on control.

[0034] Specifically, for the synchronous control method of the on-vehicle machine system provided in this embodiment, reference can be made to Figure 2 As shown in Figure 2, it is applied to the synchronous unit in the on-vehicle machine system and specifically includes the following steps:

[0035] Step S21. Receive the power-on control signal sent by the main control unit and synchronously confirm the operation status of the communication link of the main control unit.

[0036] In this embodiment, the relationship between the main control unit and the synchronous unit is that when the main control unit starts to work, the synchronous unit starts and works synchronously with respect to the main control unit. Specifically, when the main control unit starts to work, it sends a power-on control signal to the synchronous unit, and the power-on control signal is in a high-level state. When the synchronous unit receives the power-on control signal, it performs synchronous power-on and then starts to work. This process is the same as the synchronous control method in the prior art.

[0037] However, as described in the prior art, if only the above-mentioned synchronous control method is adopted, there are many technical defects.

[0038] Therefore, for the control of the synchronization unit in this embodiment, it is not only necessary to receive and verify the power-on control signal sent by the master control unit, but also the verification of the operating state of the communication link is added. That is, in this embodiment, in order to realize the working control of the synchronization unit, a verification data, that is, the operating state of the communication link of the current master control unit, is added, reducing the problem of uncontrollable risks caused by a single verification logic.

[0039] The communication link of the master control unit refers to the communication link between the master control unit and the synchronization unit, and the confirmation of the operating state of the communication link of the master control unit refers to the confirmation of the working state of the communication link between the master control unit and the synchronization unit. And the working state refers to whether the current communication link is established.

[0040] For how to perform working control on the synchronization unit for the above-mentioned signals and working states obtained, please refer to the following steps.

[0041] Step S22-1. When any one of the power-on control signal and the communication link operating state meets the working conditions, keep the state of the synchronization unit as the working state.

[0042] In this embodiment, for the power-on control signal to meet the working conditions means that the synchronization unit receives the power-on control signal sent by the master control unit and the level of the power-on control signal is in the high-level state. For the communication link operating state to meet the working conditions means that the synchronization unit receives the communication information sent by the master control unit. For the working state of the synchronization unit means that the synchronization unit is powered on and enabled.

[0043] Among them, the power-on and enabling of the synchronization unit are synchronously determined by the two conditions that the power-on control signal is received and the communication link is established. However, it should be noted that the synchronous determination in this embodiment does not mean that both of the above two conditions should be met, but only one of the above two conditions needs to be met. That is, when the synchronization unit receives the high-level power-on control signal sent by the master control unit, or the current communication link has been established, it means that the master control unit has been powered on, and at this time the synchronization unit performs synchronous power-on.

[0044] The significance of processing through the above method is that when the master control unit has been successfully powered on, but due to hardware problems or other problems in the transmission of the power-on control signal, the power-on and enabling can be determined by determining the state of the communication link, avoiding the control error problem caused by a single control logic.

[0045] Step S22-2. When both the power-on control signal and the communication link operating state do not meet the working conditions, the operating state of the synchronization unit changes from the working state to the closed state.

[0046] Regarding the power-down control corresponding to the power-on control in step S22-1, that is, how to implement the power-down of the synchronization unit. Different from step S22-1, the determination of the power-down control requires both a control signal and a communication link to trigger simultaneously.

[0047] Among them, the power-on control signal not meeting the working conditions means that the level state of the power-on control signal received by the synchronization unit is low level, and the communication link operating state not meeting the working conditions means that the synchronization unit cannot receive the communication information sent by the control unit. When the above two situations occur simultaneously, it means that the main control unit changes from the power-on state to the power-down state, that is, it no longer works, and correspondingly, it cannot send a power-on control signal and communication information with a high level state to the synchronization unit. Therefore, when the synchronization unit receives the above two situations simultaneously, it correspondingly changes the power-on state to the power-down state, and the state machine changes from the working state to the closed state.

[0048] In summary, for a synchronization control method in a rail vehicle machine system provided in this embodiment, by setting two synchronization unit working trigger mechanisms, the work control of the synchronization unit changes from being activated by a single control signal in the prior art to being synchronously activated by a control signal and communication information, fundamentally solving the problem of the black screen failure of the human-machine interaction unit caused by abnormal power-on control signals during the operation of the existing solution, solving the problem of unstable hardware transmission of key signals caused by connector material problems, solving the problem of short-circuit of the power-on control signal caused by a single module failure during operation, creating conditions for timely and effective handling of faults, greatly improving the reliability of the system, and effectively ensuring the operation safety of trains and railway lines.

[0049] Refer to Figure 3 , the embodiment of the present invention provides a readable medium 30, and the readable medium 30 stores computer-readable instructions 301, and the computer-readable instructions 301 include instructions for executing the synchronization control method in the rail vehicle machine system described above.

[0050] The functions and technical effects of the readable medium 30 provided in the embodiment of the present invention can refer to the technical effects of the calibration method in the foregoing embodiments, and will not be elaborated here.

[0051] Regarding the system architecture of the rail vehicle machine system in the embodiment of the present invention, please refer to Figure 4 , regarding the rail vehicle machine system 40 including a main control unit 41 and a synchronization unit 42, the synchronization unit is controlled by the main control unit.

[0052] Among them, in this embodiment, the main control unit is the host, and the synchronization unit is the human-machine interface unit. Among them, both the main control unit and the synchronization unit are provided with a power supply module and an information processing module, namely the first power supply module 411, the second power supply module 421, the first information processing module 412, and the second information processing module 422 respectively. The first power supply module 411 of the main control unit is used to generate a power-on control signal, and the second power supply module 421 of the synchronization unit is used to receive the power-on control signal and determine the level state of the power-on control signal. The information processing module is used for the establishment of the communication link.

[0053] It should be noted that the rail vehicle system in this embodiment is different from the prior art in that a processing module 423 is further provided in the synchronization unit in this embodiment. The processing module 423 is electrically connected to the second power supply module 421 and the information processing module 422 in the synchronization unit, and is used to receive the above-mentioned power-on control signal, determine the level state of the power-on control signal, and monitor the communication link, and realize the control of the power-on and power-off of the synchronization unit by judging the two situations of the level state and the communication link.

[0054] Among them, the control method is realized by executing the process from step S21 to step S22.

[0055] Specifically, the processing module is used to receive the level state of the power-on control signal at the current moment and the running state of the communication link at the current moment, and judge whether the synchronization unit meets the working conditions based on the above two states. Among them, whether it meets the working conditions refers to whether a power-on control operation needs to be performed.

[0056] Among them, the determination of the level state of the power-on control signal at the current moment is realized by the signal sent by the host power supply module. When the level of the power-on control signal is high, it means that the level state of the power-on control signal is in a high level state at this time. When the level of the power-on control signal is low, it means that the level state of the power-on control signal is in a low level state at this time.

[0057] The determination of the running state of the communication link is realized by the information processing module in the synchronization unit. Among them, the running state of the communication link includes normal and abnormal. Among them, the normal state of the communication link means that the information processing module in the main control unit and the information processing module in the synchronization unit send and receive communication information with each other and are received; the abnormal state of the communication link means that the information processing module in the main control unit does not send communication information.

[0058] The operating conditions in this embodiment refer to the state conditions under which the synchronization unit can be powered on and operate. When the level state of the power-on control signal is high or the operating state of the communication link is normal, it indicates that the current synchronization unit can operate, and thus the processing module performs a power-on operation on the synchronization unit.

[0059] Among them, the processing module obtains the level state of the power-on control signal directly based on the power-on control signal issued by the main control unit; while the acquisition of the operating state of the communication link is achieved through the signal instructions sent by the information processing module.

[0060] Specifically, for the information processing module set in the synchronization unit, corresponding instruction signals are sent to the processing module according to the current state of the communication link. When the current communication link is normal, the information processing module sends an internal power-on control signal with a high level to the processing module; otherwise, it sends an internal power-on control signal with a low level to the processing module.

[0061] When the processing module receives both the power-on control signal with a low level issued by the main control unit and the internal power-on control signal with a low level issued by the information processing module at the same time, the power-off control is started. When any one of the above power-on control signals is high, the power-on control is started.

[0062] In summary, the rail locomotive system provided by the embodiment of the present application is used to implement the power-on control and power-off control of the synchronization unit, that is, the human-machine interaction unit. The control sequence is described again as follows:

[0063] 1. When the main control unit, that is, the monitoring host, is powered on, the power-on control signal is in a high level state, and the power supply module of the synchronization unit, that is, the human-machine interaction unit, starts to operate;

[0064] 2. After the human-machine interaction unit is powered on, the communication between the monitoring host and the human-machine interaction unit is normal, and the internal power-on control signal is in a high level state;

[0065] 3. During the operation of the system, both the power-on control signal and the internal power-on control signal are high, and the power supply module of the human-machine interaction unit can maintain operation when any one of the power-on control signals is high;

[0066] 4. When the monitoring host is powered off, the power-on control signal is low, the communication is abnormal, the internal power-on control signal is low, the power supply module of the human-machine interaction unit stops operating, and the human-machine interaction unit is powered off synchronously.
