Furthermore, after receiving the safety command, the interlock device needs to compare whether the safety command is consistent every time, and only when the safety command is consistent, the interlock device sends the safety command to the target object and executes the safety command, so that the situations that the target object executes a wrong safety command or controls a wrong target object by the interlock device and the like can be further avoided.

A train safety control method and apparatus according to an embodiment of the present invention will be described below with reference to the accompanying drawings. Before describing embodiments of the present invention in detail, for ease of understanding, common terminology will be introduced first:
common Cause Failure (CCF) refers to the simultaneous Failure of two or more units in a system due to some Common Cause.
Fig. 1 is a schematic flow chart of a train safety control method according to an embodiment of the present invention.
The execution subject of the embodiment of the invention is ATS.
As shown in fig. 1, the safety control method of the train includes the steps of:
In the embodiment of the invention, the target object can be a signal machine, a turnout and/or a track section which needs to issue a safety command. The security command may include a command for blocking or unblocking the target object, and any other command for controlling the target object.
Specifically, the operator may select a target object to which a security command is to be issued on a display interface of the ATS, and accordingly, the ATS may receive or detect a selection operation of the operator, and then generate the security command according to the selection operation.
And 102, extracting the identification of the target object from the safety command, and verifying the identification of the target object.
In the embodiment of the present invention, the identifier of the target object is used to uniquely identify the target object, and the identifier of the target object may be, for example, an Identification (ID) of the target object, or any other character information that uniquely identifies the target object, which is not limited herein.
It should be noted that, in order to prevent the interlock device from transmitting a wrong safety command, or in order to prevent an operator from inadvertently transmitting a wrong name of a target object, which results in the interlock device controlling a wrong target object to execute the safety command, in the embodiment of the present invention, the identifier of the target object may be extracted from the safety command, and the identifier of the target object may be verified.
For example, when the operator wants to send a security command to the device a and the security command is used to block or unblock the device a, but the name of the device is mistakenly input due to random failure of hardware, failure of a software program, or negligence of the operator, the security command is changed to be used to block or unblock the device B when the ATS transmits the security command to the ATS control unit through the ATS server. At this time, if the identification of the target object in the safety command is not verified, the ATS control unit sends the safety command to the interlock device, and the interlock device locks or unlocks the control device B. It will be appreciated that the availability of the device B will be affected when the non-faulty device B is blocked, whereas the faulty device a is not blocked, possibly leading to a dangerous accident situation.
In the embodiment of the invention, in order to guarantee the safety of train running, the ATS can verify the identification of the target object in the safety command at least twice.
Specifically, when the ATS receives the security command for the first time, the identifier of the target object may be displayed to the operator through the display interface, and the operator determines whether the target object is an object to which the security command needs to be issued. If so, the verification is passed, at this time, step 103 may be triggered, and if not, the verification is failed, at this time, step 101 may be executed again, and the target object to which the safety command needs to be issued is input again by the operator, or when the verification is failed, a situation that the safety command is triggered by the operator by mistake may occur, at this time, in order to ensure the safety of train operation, the process may be ended, that is, step 107 is executed.
When the ATS receives the security command for a non-first time, the currently input identifier of the target object may be compared with the previously input identifier of the target object, and if the currently input identifier of the target object is consistent with the previously input identifier of the target object, the step 103 may be triggered by verifying the identifier of the target object; if not, the identification of the target object is not verified, and at this time, a fault may occur, so the process may be ended, that is, step 107 is executed, further, when a fault occurs, fault information may also be reported, for example, fault information may be displayed on a display interface of the ATS, so that an operator may take a relevant measure to process the fault.
Specifically, when the safety command is received for the first time and the verification is passed, the operator may input the safety command again on the display interface of the ATS, and accordingly, the ATS may listen to the safety command input again by the operator. As a possible implementation manner, the ATS may detect a confirmation operation input by an operator through the display interface, and when the confirmation operation is detected, the ATS displays a reminder for re-inputting the safety command through the display interface, so that the operator may re-input the safety command according to the reminder, and accordingly, the ATS may receive the safety command re-input by the operator. For example, the display interface may have an "ok" button, the ATS may detect whether the operator has triggered the "ok" button, and when the ATS detects that the operator has triggered the "ok" button, a reminder to re-enter the security command may be displayed through the display interface, so that the operator may re-enter the security command.
When the safety command is not received for the first time, the prompt for inputting the safety command again can be displayed through the display interface when the identification of the target object is verified, so that the operator can input the safety command again according to the prompt.
Correspondingly, the ATS may monitor a safety command input by an operator, and determine whether the safety command is monitored, if so, perform step 104, otherwise, perform step 107.
In the embodiment of the present invention, when the ATS monitors the security command, the ATS further needs to determine whether the secondary verification is the last verification, and when the secondary verification is the last verification, step 105 may be triggered, and when the verification is not the last verification, step 106 may be triggered. Specifically, the ATS may count the number of received security commands, and compare the counted number with a preset number. If the counted number of times is the same as the preset number of times, the current verification is the last verification.
And 105, packaging the received safety command each time and then sending the safety command to the interlocking equipment, and sending the safety command to the target object and executing the safety command when the interlocking equipment compares that the safety command is consistent each time.
Optionally, when the verification is the last verification, the ATS control unit may package the received safety command each time and send the packaged safety command to the interlock device, and accordingly, after receiving the packaged data, the interlock device may perform unpacking processing on the packaged data to obtain the safety command received by the ATS each time. It should be noted that, after acquiring the safety command received by the ATS each time, the interlock device may compare whether the safety command is consistent each time, and only if the safety command is consistent, the interlock device sends the safety command to the target object and executes the safety command, so that the target object may be prevented from executing an incorrect safety command or an incorrect target object controlled by the interlock device. And when the two objects are inconsistent, the safety command is not sent to the target object, at this time, in order to guarantee the safety of train running, the interlocking device can report fault information to the ATS, and the ATS can display the fault information on a display interface after receiving the fault information, so that an operator can take relevant measures to process the fault.
Further, in order to ensure the safety of the communication between the ATS and the interlock device, the ATS and the interlock device may communicate using a safety communication protocol.
And step 106, returning to monitor the security command input again and continuing the next verification process by subsequent operations.
Optionally, when the verification is not the last verification, the ATS needs to listen again to the security command input again, i.e. return to step 103 and subsequent steps.
And step 107, ending the process.
In the embodiment of the invention, when the safety command input again is not monitored, the situation that the safety command is triggered by the operator by mistake may occur, and at the moment, the process can be ended in order to ensure the safety of train operation.
It should be noted that, in order to ensure the safety of train running, during each verification process, the operator may cancel the safety command and end the process at any time, for example, a "cancel" button may be provided on the display interface of the ATS, so that the operator may end the process by triggering the "cancel" button.
In the safety control method of the train of the embodiment, a safety command for issuing a target object is received; extracting the identification of the target object from the safety command, and verifying the identification of the target object; monitoring a safety command input again when the verification passes, and if the safety command is monitored, judging whether the current verification is the last verification; if the safety command input again is not monitored, the process is ended; if the verification is the last time, the received safety command is packaged and then sent to the interlocking equipment, and the interlocking equipment sends the safety command to the target object and executes the safety command when comparing that the safety command is consistent each time; if not, returning to monitor the security command input again and continuing the next authentication process by subsequent operations. In this embodiment, the ATS verifies the safety command at least twice, so that the probability of the incorrect safety command sent to the interlock device can be reduced, and the situations that the target object executes the incorrect safety command or the interlock device controls the incorrect target object, and the like, can be avoided. Furthermore, after receiving the safety command, the interlock device needs to compare whether the safety command is consistent every time, and only when the safety command is consistent, the interlock device sends the safety command to the target object and executes the safety command, so that the situations that the target object executes a wrong safety command or controls a wrong target object by the interlock device and the like can be further avoided.
In addition, in the embodiment of the invention, the ATS verifies the safety command at least twice, the ATS only needs to package the safety command received each time and then send the safety command to the interlocking equipment, and the interlocking equipment performs consistency comparison, thereby not only ensuring the running safety of the train, but also simplifying the information interaction process between the ATS and the interlocking equipment.
As a possible implementation manner, referring to fig. 2, on the basis of the embodiment shown in fig. 1, step 105 may specifically include the following sub-steps:
In the embodiment of the invention, the target object can generate the execution result after executing the safety command, so that the ATS can judge whether the target equipment is abnormal or not according to the execution result.
For example, when the security command is a command for blocking or unblocking the target object, the target object may generate an execution result after executing the security command, so that the ATS may obtain a state of the target object according to the execution result, and further may determine whether the target device is abnormal according to the state of the target object. The state of the target object may be an locked state or an unlocked state.
Specifically, after the interlock device sends the safety command to the target object and executes the safety command, the target object may return the execution result to the interlock device, and after receiving the execution result, the interlock device may return the execution result to the ATS, and accordingly, the ATS may obtain the execution result returned by the interlock device.
Specifically, after the ATS receives the execution result, it may be determined whether the target object is abnormal according to the execution result.
For example, when the security command is used to block or unblock the target object, the ATS may obtain a state of the target object according to the execution result, and may further determine whether the target object is abnormal according to the state of the target object.
Specifically, if the execution result indicates that the state of the target object is the unlocked state, and the security command is used for blocking the target object, it indicates that the target object is abnormal.
And if the execution result indicates that the state of the target object is the unlocking state and the safety command is used for unlocking the target object, indicating that the target object is not abnormal.
And if the execution result indicates that the state of the target object is a blocked state and the security command is used for unlocking the target object, the target object is abnormal.
If the execution result indicates that the state of the target object is a blocking state, and the security command is used for blocking the target object, it indicates that the target object is not abnormal.
Specifically, the interlocking device may acquire the position information of the target object, and then the interlocking device may send the position information of the target object to the ATS server through the ATS control unit, and after receiving the position information of the target object, the ATS server may send the position information of the target object to a display interface of the ATS for display.
And 1054, acquiring the train running to the target object according to the position information.
Optionally, after receiving the location information of the target object, the ATS may send a request message to the train dispatching center according to the location information, where the request message carries the location information of the target object, and the train dispatching center may determine, according to the location information and a running state of the running train, such as a location and a running direction, a train running towards the target object, and then send the train to the ATS.
And 1055, sending alarm information to the train running to the target object, wherein the alarm information carries the identification of the target object.
In the embodiment of the invention, after the ATS acquires the train which is running to the target object, the ATS can send the warning information to the train which is running to the target object, and the warning information carries the identification of the target object, so that a train driver can control the train to stop outside the preset range of the target object after receiving the warning information, and accidents are avoided.
According to the train safety control method, the execution result returned by the interlocking device is received, whether the target object is abnormal or not is judged according to the execution result, if the target object is abnormal, warning information is sent to the train running to the target object, and the warning information carries the identification of the target object. Therefore, when the target object is abnormal, the warning information can be sent to the train running to the target object in time, and the train driver can control the train to stop outside the preset range of the target object after receiving the warning information, so that accidents are avoided, and the running safety of the train is further guaranteed.
As a possible implementation manner, in order to ensure the security of information transmission, in the embodiment of the present invention, after the ATS receives the security command, the ATS may perform encoding processing on the security command, for example, an encoding algorithm in the prior art may be used to perform encoding processing on the security command, so as to obtain an encoded security command.
Extracting the identifier of the target object from the security command, which specifically includes: the encoding security command can be decoded by adopting a decoding algorithm corresponding to the encoding algorithm to obtain the security command, so that the identification of the target object can be extracted from the security command.
It should be noted that, when the security command is encoded in the same manner in each authentication process, a common cause failure may occur, so that the security command cannot be detected. Therefore, in the embodiment of the invention, the encoding modes of the security command in each verification process can be different, so that the effectiveness of the security command in the transmission process is improved.
As an example, referring to fig. 3, fig. 3 is a schematic flow chart of a train safety control method according to a third embodiment of the present invention. Fig. 3 illustrates two authentication instances with an ATS for the identification of a target object in a security command. An operator can input a safety command on a display interface of the ATS, after the ATS receives the safety command, the safety command can be encoded by adopting an encoding mode A, then the encoded safety command is sent to the ATS control unit, the ATS control unit decodes the safety command, and the safety command is returned to the display interface of the ATS through the ATS server. Correspondingly, after receiving the safety command, the ATS can display the safety command on a display interface, verify the safety command, judge whether a target object in the safety command is consistent with a target object input by an operator, if not, finish the process, if so, remind the operator to input the safety command again, encode the safety command input by the operator by adopting an encoding mode B, and send the encoded safety command to the ATS control unit. The ATS control unit decodes the coded safety command, compares the two safety commands, and if the identification of the target object input at the time is consistent with the identification of the target object input before, the ATS control unit can package the safety commands received twice through a safety communication protocol and then send the safety commands to the interlocking equipment. And the interlocking device sends the safety command to the target object and executes the safety command when comparing that the safety command is consistent each time. And when the two states are inconsistent, the safety command is not sent to the interlocking device, and further, when the two states are inconsistent, fault information can be displayed on a display interface of the ATS, so that an operator can take relevant measures to process the fault.
It should be noted that, when the operator erroneously triggers a safety command, for example, the operator erroneously triggers a safety command for unlocking a target object, after receiving the erroneously triggered safety command, the interlock device will allow the train to enter the fault area, which may also cause a serious accident. Or when the operator triggers the safety command for blocking the target object by mistake, the interlocking device prohibits the train from entering the fault area after receiving the safety command triggered by mistake, thereby influencing the usability of the target object. Therefore, in the embodiment of the present invention, in order to avoid the above situation, the authentication and authorization may be performed on the operator. The above process is described in detail below with reference to fig. 4.
Fig. 4 is a schematic flow chart of a train safety control method according to a fourth embodiment of the present invention.
As shown in fig. 4, on the basis of the embodiments shown in fig. 1 to 3, before step 101, the safety control method for a train may further include the following steps:
In the embodiment of the present invention, the authentication information input by the operator may be character password information, biometric information, graphic password information, motion information, and the like, which is not limited. The biometric information may be a fingerprint, an iris, a facial phase, DNA, etc., and the motion information includes the motion made by a facial organ, the motion made by a limb, and/or the motion made by a body, and the number and/or frequency of each motion.
In the embodiment of the invention, the pre-stored authentication information is information which is pre-input on a display interface of the ATS by an authorized operator.
Alternatively, the received authentication information may be compared with pre-stored authentication information, so that it may be determined whether the operator who inputs the authentication information is an authorized operator.
Optionally, to avoid triggering the security command by an unauthorized person or to avoid triggering the security command by an authorized person by mistake, in the embodiment of the present invention, it may be determined whether the two authentication information are consistent, and when the two authentication information are consistent, step 204 may be triggered, and when the two authentication information are inconsistent, step 205 may be triggered.
In the embodiment of the present invention, after the operator is authenticated, the steps in fig. 1 to fig. 3 may be executed.
In the embodiment of the invention, when the authentication of the operator is not passed, no treatment is required.
In the safety control method of the train of the embodiment, the authentication information input by an operator is received; comparing the received authentication information with prestored authentication information; if the two authentication information are consistent, the operator is authenticated. Therefore, the safety command can be prevented from being triggered by unauthorized personnel, or the safety command can be prevented from being triggered by authorized personnel by mistake, so that the running safety of the train is further guaranteed.
In order to realize the embodiment, the invention further provides a safety control device of the train.
Fig. 5 is a schematic structural diagram of a safety control device for a train according to an embodiment of the present invention.
As shown in fig. 5, the safety control device 100 for a train includes: a receiving module 110, an extracting module 120, a listening module 130, and a processing module 140. Wherein the content of the first and second substances,
