Background
In the prior art, when a signaling system in a rail transit system checks the status of a platform device (e.g., a platform door), there is typically both bypass and isolation status when the platform device fails. Wherein bypass is an operational mode that allows system operations to bypass the checking mechanism to continue normal operation, and isolation is an operational mode that allows system operations to bypass the checking mechanism to continue degraded operation. The bypass and isolation avoid the due checking mechanism of the system, when the platform equipment is in error bypass or isolation, the signal system does not check whether the platform door is closed and locked, in which case if the signal system judges that the train is allowed to start if the departure condition is met, but the platform door is not actually closed, serious potential safety hazard may be brought.

Detailed Description
Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the disclosure, are not intended to limit the disclosure.
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
The applicant has found that in existing security detection schemes for rail transit systems, system operations can bypass the inspection mechanism when a platform device reports a device bypass or isolation status. For example, when a certain side platform door bypasses, the signal system does not check the state of the side platform door, and the door control operation is normally performed. When a certain platform door is isolated, the signal system does not check the state of the platform door, but performs alignment isolation of train doors on the failed platform door, wherein alignment isolation refers to isolation operation on the doors at the positions corresponding to the platform doors, for example, after a certain platform door fails, the doors corresponding to the platform door are not opened after alignment isolation is performed on the platform door.
Since both bypass and isolation circumvent the system's due checking mechanism, conditions that would otherwise need to be checked need to be guaranteed by other means, such as transfer to manual or transfer to other equipment. But based on the manual inspection mode, on one hand, the full automation degree of the system is reduced, on the other hand, the operation skill requirement of operators is improved, the operation cost is increased, and the inspection accuracy is unstable due to the proficiency and experience difference of the operators, so that the inspection is performed manually, and the higher failure rate exists.
In order to solve the above technical problems, the present disclosure provides a security detection method, an electronic device, and a storage medium. The method provides a confirmation mechanism for bypass and isolation in a rail transit system, and confirms based on interaction of a signal system and a control center. The security detection method provided by the present disclosure is described below.
The technical scheme of the present disclosure will be described in detail with reference to specific embodiments.
Fig. 1 is a flowchart of a security detection method according to an embodiment of the present disclosure, where the method is applied to a signal system, as shown in fig. 1, and the method includes:
In step S101, in the case where it is determined that the current state of the target device is the first state, first request information is sent to the control center, where the first request information is used to instruct the control center to output alarm prompt information, where the alarm prompt information is used to confirm whether the first state of the target device is valid, and the first state includes bypass or isolation.
For example, when the signal system collects status information of the bypass or isolation of the target device, the signal system may not directly determine whether the bypass or isolation is valid, and at this time the signal system may still continue to process as if the target device is not bypassed or isolated. And after receiving the bypass or isolation state of the target equipment, the signal system sends the first request information to the control center, and the control center can output alarm prompt information, such as a primary alarm prompt, on a man-machine operation interface of the control center in a popup window mode based on the received first request information so as to remind a dispatcher of the control center whether the target equipment is allowed to bypass or isolate, so that the dispatcher can confirm the bypass or isolation for the first time.
In one possible implementation, the dispatcher may trigger the control center to send a detection instruction to the field device at the location of the target device, so as to instruct the field device to confirm whether the bypass or isolation state of the target device is valid, and feed back a confirmation result to the control center, where the control center returns a first confirmation signal or rejection signal to the signaling system according to the confirmation result.
Optionally, the signal system is a signal system in a rail transit system, and the signal system may include one or more subsystems of an ATS (Automatic Train Supervision, train automatic monitoring) system, a CI (Computer Interlocking, computer interlock), a VOBC (Vehicle On-board Controller), a ZC (Zone Controller), an OC (Object Controller, target Controller), the target device including a train device in the rail transit system, and/or a trackside device.
By way of example, the target device may be a device that may pose a safety risk in a bypass or isolation state, such as a trackside device that may include a platform door device, a car washer device, a charging stake device, an emergency stop button device, and a train device that may include a train door device, a train escape door, or the like.
In step S102, when a first acknowledgement signal returned by the control center in response to the first request information is received, second request information is sent to the control center, where the second request information is used to instruct the control center to output the alarm prompt information again.
After receiving the first confirmation signal, the signal system can confirm the control center again, send the second request information, and after receiving the second request information, the control center outputs the alarm prompt information again, and the method for outputting the alarm prompt information is the same as the method for outputting the alarm prompt information after receiving the first request information, and the method for feeding back the second confirmation signal and the first confirmation signal by the control center is the same, which can refer to step S101 and is not repeated.
In step S103, in the case of receiving a secondary acknowledgement signal returned by the control center in response to the second request information, it is determined that the first state of the target device is valid.
In the event that the bypass or isolation status of the target device is determined to be valid, the signaling system allows the target device to perform a corresponding operation in accordance with the bypass or isolation status.
Optionally, the method may further include, after step S101: and determining that the first state of the target device is invalid under the condition that a first rejection signal returned by the control center in response to the first request information is received.
Optionally, the method may further include, after step S102: and determining that the first state of the target device is invalid when a second rejection signal returned by the control center in response to the second request information is received.
That is, after the signal system sends the first request information, if the first rejection signal sent by the control center is received, the control center determines that the bypass or isolation state of the target device is invalid, and the first confirmation is not passed, the signal system does not allow the bypass or isolation of the target device. After the signal system sends the second request information, if the second rejection signal sent by the control center is received, the control center determines that the bypass or isolation state of the target device is invalid in the secondary confirmation, and the secondary confirmation does not pass, the signal system does not allow the bypass or isolation of the target device.
Optionally, the method further comprises: after determining that the first state of the target device is invalid, a reset operation is performed on the target device.
Through the technical scheme, the secondary confirmation mechanism for the bypass and the isolation in the rail transit system is provided, and is realized through secondary confirmation by the signal system and the control center.
Fig. 2 is a flowchart of another security detection method provided in an embodiment of the present disclosure, where the method is applied to a control center, as shown in fig. 2, and includes:
in step S201, in response to the first request information sent by the signal system, alarm prompt information is output, where the first request information is sent by the signal system in a case where the target device is determined to be in the first state, and the alarm prompt is used to confirm whether the first state of the target device is valid.
In step S202, a first acknowledgement signal is sent to the signaling system based on a first acknowledgement result sent by the field device that characterizes the first state of the target device as valid.
For example, in one possible implementation manner, the control center may output alarm prompt information, such as a first-level alarm prompt, on a man-machine operation interface of the control center in a popup window manner based on the received first request information, so as to remind a dispatcher of the control center whether to allow the target device to bypass or isolate, so that the dispatcher can perform first confirmation of bypass or isolation.
The dispatcher can trigger the control center to send a detection instruction to the field device at the site of the target device to instruct the field device to confirm whether the bypass or isolation state of the target device is effective or not, and feed back a confirmation result to the control center, and the control center returns a first confirmation signal or rejection signal to the signal system according to the confirmation result.
The field device may be a video monitoring device, such as a CCTV monitoring system, or may be a communication terminal for a crew. The control center can control the CCTV monitoring system to carry out remote confirmation or instruct the station personnel to carry out confirmation through the communication terminal of the station personnel.
In step S203, the alarm prompt information is output again in response to the second request information sent by the signal system, which is sent by the signal system upon receipt of the first acknowledgement signal.
The method for the control center to output the alarm prompt information again based on the second request information by sending the second request information by the signal system can refer to step S103, and will not be described again.
In step S204, a secondary acknowledgement signal is sent to the signaling system indicating that the first state of the target device is valid based on a second acknowledgement result sent by the field device that characterizes the first state of the target device as valid.
And the signal system determines that the first state of the target equipment is effective under the condition of receiving a secondary confirmation signal returned by the control center and responding to the second request information, and allows the target equipment to perform corresponding operation according to the bypass or isolation state under the condition of determining that the bypass or isolation state of the target equipment is effective.
The target device may be a device that may pose a safety risk in a bypass or isolation state, such as a trackside device that may include a platform door device, a car washer device, a charging pile device, an emergency stop button device, and a train device that may include a train door device, a train escape door, or the like.
Through the technical scheme, the secondary confirmation mechanism for the bypass and the isolation in the rail transit system is provided, and is realized through secondary confirmation by the signal system and the control center.
Fig. 3 is a flowchart of yet another security detection method provided by an embodiment of the present disclosure, referring to fig. 3, the method may include the steps of:
in step S301, the signaling system detects a first state of the target device, the first state including bypass or isolation.
In step S302, the signaling system sends first request information to the control center, where the first request information is used to instruct the control center to output alarm prompt information, and the alarm prompt information is used to confirm whether the first state of the target device is valid.
The content in step S101 may be referred to, and will not be described in detail.
In step S303, the control center responds to the first request information sent by the signal system, and outputs alarm prompt information, where the alarm prompt is used to confirm whether the first state of the target device is valid.
The content in step S102 may be referred to, and will not be described in detail.
Step S304, the control center sends a first confirmation signal to the signal system based on a first confirmation result which is sent by the field device and is used for representing that the first state of the target device is valid.
In one embodiment, where the field device is a video monitoring device and the target device is located within the detection range of the field device, step S304 may include:
transmitting a detection instruction to the field device, wherein the detection instruction is used for instructing the field device to remotely confirm the first state of the target device based on a monitoring video;
and receiving the first confirmation result sent by the field device under the condition that the first state of the target device is confirmed to be valid by the field device.
The video monitoring device described above may be, for example, a monitoring device in a CCTV monitoring system, such as a monitoring camera disposed near a target device, which can determine whether a first state of the target device is valid by capturing an image of the target device and performing image analysis.
In another embodiment, in the case where the field device is a communication terminal of a crew member, step S304 may include:
and sending a security state check message to the communication terminal, wherein the security state check message is used for indicating the station personnel to confirm the first state of the target equipment. For example, the communication terminal may be an interphone of a station person, and a dispatcher of the control center may communicate with the station person near the target device through the interphone and instruct the station person to confirm the first state of the target device.
And when the control center determines that the first state of the target equipment is valid based on the monitoring equipment or the communication terminal of the station personnel, a first confirmation signal is sent to the signal system.
In step S305, the signaling system sends second request information to the control center when receiving a first acknowledgement signal returned by the control center and responding to the first request information, where the second request information is used to instruct the control center to output alarm prompt information again.
In step S306, the control system outputs the alarm prompt information again in response to the second request information sent by the signal system.
The method of the signal system sending the second request information and the control center outputting the alarm prompt information again based on the second request information may refer to step S103, which is not described herein.
Step S307, based on the second confirmation result sent by the field device, which characterizes the first state of the target device as valid, sends a secondary confirmation signal to the signal system.
In step S308, the signal system determines that the first state of the target device is valid when receiving the secondary acknowledgement signal returned by the control center in response to the second request information.
Through the steps S301 to S308, the bypass or isolation state of the target device is determined to be valid through the secondary confirmation of the control center, and the signal system allows the target device to perform a corresponding operation according to the bypass or isolation state if it is determined that the bypass or isolation state of the target device is valid.
Alternatively, after step S303, it may further include:
in step S309, the control center sends a first rejection signal to the signaling system based on the third confirmation result sent by the field device, which characterizes that the first state of the target device is invalid.
In step S310, the signaling system determines that the first state of the target device is invalid when receiving a first rejection signal returned by the control center.
Alternatively, after step S306, it may further include:
in step S311, the control center sends a second rejection signal to the signal system based on the fourth confirmation result sent by the field device, which characterizes that the first state of the target device is invalid.
In step S312, the signaling system determines that the first state of the target device is invalid when receiving a second rejection signal returned from the control center.
That is, after the signal system sends the first request information, if the first rejection signal sent by the control center is received, the control center determines that the bypass or isolation state of the target device is invalid, and the first confirmation is not passed, the signal system does not allow the bypass or isolation of the target device. After the signal system sends the second request information, if the second rejection signal sent by the control center is received, the control center determines that the bypass or isolation state of the target device is invalid in the secondary confirmation, and the secondary confirmation does not pass, the signal system does not allow the bypass or isolation of the target device.
After step S310 or step S312, it may further include:
in step S313, after determining that the first state of the target device is invalid, a reset operation is performed on the target device.
It should be noted that the information transmitted between the signal system and the control center, and between the control center and the field device can ensure the correctness of the transmitted information through the safety design of hardware redundancy comparison or the software heterogeneous coding of the two commands.
The hardware redundancy comparison is realized through hardware, for example, two sets of hardware are used for executing a command, for example, a command is issued through man-machine interaction, the command is processed through two CPUs, and the command is output only when the processing results of the two CPUs are consistent; the software heterogeneous code may be obtained by running two software codes on one piece of hardware, for example for: 2+2+2+2=10, may also be represented as 2*5 =10, and if the final running result of the two coding modes is the same, the result will be output, and the accuracy of the system transmission information can be improved by the above mode.
In summary, the above technical solution provides a secondary confirmation mechanism for bypass and isolation in a rail transit system, where the mechanism is implemented by performing secondary confirmation through a signal system and a control center, and compared with the manner of manually confirming the bypass and isolation state in the related art, the present disclosure solves the problems of higher failure rate and low system automation degree existing in relying on manual operation, and achieves the effects of performing safety protection on error bypass or error isolation, effectively avoiding the safety risk after error bypass or error isolation, and reducing the probability of casualties of personnel.
