Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of transportation, in particular, to a safety detection method, an electronic device and a storage medium. BACKGROUND

[0002] In the prior art, when the signal system in the rail transit system checks the state of the platform equipment (such as platform doors), there are usually two states of bypass and isolation when the platform equipment fails. The bypass is a mode of operation that enables the system to continue normal operation by bypassing the checking mechanism, and the isolation is a mode of operation that enables the system to continue degraded operation by bypassing the checking mechanism. Both bypass and isolation avoid the proper checking mechanism of the system. When the platform equipment is wrongly bypassed or isolated, the signal system does not check whether the platform door is closed and locked. In this case, if the signal system judges that the train is allowed to start under the condition of meeting the departure condition, but the platform door is actually not closed, it may cause serious safety hazards.

[0065] The specific embodiments of the present disclosure will be described hereinafter with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of certain embodiments consistent with the present disclosure and do not limit the present disclosure in any way.

[0066] The example embodiments will be described in detail with reference to the accompanying drawings. In the following description, the same numbers are used to denote the same elements, and so on, unless otherwise indicated. The embodiments described in the following example embodiments do not represent all the embodiments 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 appended claims.

[0067] The applicant finds that in the existing safety detection scheme for rail transit systems, when a platform device reports a bypass or isolation state, the system operation can bypass the check mechanism. For example, when a side platform door is bypassed, the signal system does not check the state of the side platform door and normally performs the opening and closing of the door control operation. When a platform door is isolated, the signal system does not check the state of the platform door, but isolates the train door corresponding to the faulty platform door. Isolation refers to the isolation operation of the door corresponding to the position of the platform door. For example, when a platform door fails, the corresponding door will not be opened after the isolation of the platform door.

[0068] Since bypass and isolation both bypass the system's check mechanism, the conditions that need to be checked are guaranteed by other means, such as manual guarantee or other device guarantee. However, the manual check method reduces the degree of automation of the system, increases the operation skill requirements of the operating personnel, increases the operation cost, and due to the difference in the proficiency and experience of the operating personnel, the accuracy of the check is unstable, so the manual check method has a high failure rate.

[0069] To solve the above technical problems, the present disclosure provides a safety detection method, an electronic device and a storage medium. The method provides a confirmation mechanism for bypass and isolation in a rail transit system based on the interaction between the signal system and the control center. The safety detection method provided by the present disclosure is described below.

[0070] The technical solutions of the present disclosure will be described in detail below in combination with specific embodiments.

[0071] Figure 1 is a flowchart of a safety detection method provided by an embodiment of the present disclosure. The method is applied to a signal system, as shown in Figure 1 The method comprises the following steps.

[0072] In step S101, when it is determined that the current state of the target device is a first state, a first request information is sent to the control center, the first request information is used to instruct the control center to output an alarm prompt information, 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.

[0073] Exemplarily, when the signal system collects bypass or isolation state information of the target device, the signal system can not directly determine whether the bypass or isolation is valid, and at this time the signal system can 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 device, the signal system will send the first request information to the control center, and the control center can output alarm prompt information, for example, first-level alarm prompt, on the man-machine operation interface of the control center through the pop-up window mode based on the received first request information, to remind the dispatch personnel of the control center whether to allow the target device to bypass or isolate, so as to make the first confirmation of the dispatch personnel.

[0074] In a possible implementation, the dispatch personnel can trigger the control center to send detection instructions to the on-site device at the location of the target device, to instruct the on-site device to confirm whether the bypass or isolation state of the target device is valid, and feed back the confirmation result to the control center, and the control center returns the first confirmation signal or the rejection signal to the signal system according to the confirmation result.

[0075] Optionally, the signal system is a signal system in a rail transit system, which can include one or more subsystems of an ATS (Automatic Train Supervision), a CI (Computer Interlocking), a VOBC (Vehicle On-board Controller), a ZC (Zone Controller), and an OC (Object Controller), the target device includes train equipment and / or trackside equipment in the rail transit system.

[0076] Exemplarily, the target device can be a device that will cause a safety risk in a bypass or isolation state, for example, trackside equipment and train equipment, the trackside equipment can include platform door equipment, car washer equipment, charging pile equipment, and emergency stop button equipment, and the train equipment can include train door equipment and train escape door.

[0077] In step S102, in the case where the first confirmation signal returned by the control center in response to the first request information is received, second request information is sent to the control center, the second request information being used to instruct the control center to output the alarm prompt information again.

[0078] The signal system can send a second request information to the control center again after receiving the first confirmation signal, the control center outputs an alarm prompt information again after receiving the second request information, the method of outputting the alarm prompt information is the same as that of outputting the alarm prompt information after receiving the first request information, the method of feeding back the second confirmation signal by the control center is the same as that of feeding back the first confirmation signal, which can be referred to step S101 and will not be described here.

[0079] In step S103, in a case where the signal system receives a second confirmation 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.

[0080] In a case where it is determined that the bypass or isolation state of the target device is valid, the signal system allows the target device to perform corresponding operations according to the bypass or isolation state.

[0081] Optionally, the method can further include, after step S101, in a case where the signal system receives a first rejection signal returned by the control center in response to the first request information, determining that the first state of the target device is invalid.

[0082] Optionally, the method can further include, after step S102, in a case where the signal system receives a second rejection signal returned by the control center in response to the second request information, determining that the first state of the target device is invalid.

[0083] That is, after the signal system sends the first request information, if the signal system receives the first rejection signal sent by the control center, it indicates that the control center determines that the bypass or isolation state of the target device is invalid, the first confirmation fails, and 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 signal system receives the second rejection signal sent by the control center, it indicates that the control center determines that the bypass or isolation state of the target device is invalid in the second confirmation, the second confirmation fails, and the signal system does not allow the bypass or isolation of the target device.

[0084] Optionally, the method further includes, after determining that the first state of the target device is invalid, performing a reset operation on the target device.

[0085] Through the above technical solution, a twice confirmation mechanism for bypass and isolation in a rail transit system is provided, which is realized through twice confirmation of the signal system and the control center. Compared with the related art which relies on manual confirmation of the bypass and isolation state, the present disclosure solves the problems of high failure rate and low system automation degree caused by relying on human operation, and achieves the effects of safe protection against error bypass or error isolation, effective avoidance of safety risks after error bypass or error isolation, and reduction of the probability of personnel casualties.

[0086] Figure 2 is a flowchart of another safety detection method provided by the embodiments of the present disclosure, which is applied to a control center, as shown in Figure 2 The method comprises the following steps:

[0087] In step S201, in response to first request information sent by a signal system, output alarm prompt information, the first request information being sent by the signal system in a case where the target device is determined to be in a first state, and the alarm prompt being used to confirm whether the first state of the target device is valid.

[0088] In step S202, based on first confirmation results sent by field devices and representing that the first state of the target device is valid, send a first confirmation signal to the signal system.

[0089] For example, in a possible implementation, the control center can output alarm prompt information, for example, a first-level alarm prompt, in a pop-up manner on a man-machine operation interface of the control center based on the received first request information, to remind dispatch personnel of the control center whether to allow the target device to be bypassed or isolated, so that the dispatch personnel perform first confirmation of bypassing or isolation.

[0090] The dispatch personnel can trigger the control center to send detection instructions to field devices at the location of the target device, to instruct the field devices to confirm whether the state of bypassing or isolating the target device is valid, and feed back the confirmation results to the control center, and the control center returns a first confirmation signal or a rejection signal to the signal system according to the confirmation results.

[0091] For example, the field devices can be video monitoring devices, for example, a CCTV monitoring system, or the field devices can be communication terminals of station personnel. The control center can control the CCTV monitoring system to perform remote confirmation or instruct the station personnel to perform confirmation through the communication terminals of the station personnel.

[0092] In step S203, in response to second request information sent by the signal system, output the alarm prompt information again, the second request information being sent by the signal system in a case where the first confirmation signal is received.

[0093] The method that the signal system sends the second request information and the control center outputs the alarm prompt information again based on the second request information can refer to step S103, and will not be described herein again.

[0094] In step S204, based on second confirmation results sent by the field devices and representing that the first state of the target device is valid, send a second confirmation signal to the signal system, the second confirmation signal being used to instruct the signal system to determine that the first state of the target device is valid.

[0095] The signal system determines that the first state of the target device is valid in a case where the signal system receives a second confirmation signal returned by the control center in response to the second request information, and allows the target device to perform corresponding operation in the bypass or isolation state in a case where the signal system determines that the bypass or isolation state of the target device is valid.

[0096] The target device described above can be a device that may cause a safety risk in the bypass or isolation state, such as a trackside device and a train device. The trackside device can include a platform door device, a car washer device, a charging pile device, and an emergency stop button device. The train device can include a train door device and a train escape door.

[0097] By means of the technical solution, a secondary confirmation mechanism for bypass and isolation in a rail transit system is provided, and the secondary confirmation is realized by means of the signal system and the control center. Compared with the related art that relies on manual confirmation of the bypass and isolation state, the secondary confirmation mechanism solves the problem of high failure rate caused by reliance on human operation and low system automation, and achieves the effects of safe protection against erroneous bypass or erroneous isolation, effective avoidance of safety risks after erroneous bypass or erroneous isolation, and reduction of the probability of casualties.

[0098] Figure 3 is a flowchart of another safety detection method provided by the embodiment of the disclosure, and the method can include the following steps: Figure 3

[0099] In step S301, the signal system detects a first state of a target device, and the first state includes bypass or isolation.

[0100] In step S302, the signal system sends first request information to the control center, and 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.

[0101] The content in step S101 can be referred to, and will not be repeated here.

[0102] In step S303, the control center outputs alarm prompt information in response to the first request information sent by the signal system, and the alarm prompt information is used to confirm whether the first state of the target device is valid.

[0103] The content in step S102 can be referred to, and will not be repeated here.

[0104] In step S304, the control center sends a first confirmation signal to the signal system based on a first confirmation result sent by the field device and indicating that the first state of the target device is valid.

[0105] ​In an embodiment, in a case where the field device is a video monitoring device and the target device is located within a detection range of the field device, step S304 can include:

[0106] sending a detection instruction to the field device, the detection instruction being used to instruct the field device to remotely confirm the first state of the target device based on a monitoring video;

[0107] in a case where the field device confirms that the first state of the target device is valid, receiving the first confirmation result sent by the field device.

[0108] For example, the video monitoring device described above can be a monitoring device in a CCTV monitoring system, such as a monitoring camera arranged near the target device, which can determine whether the first state of the target device is valid by capturing an image of the target device and performing image analysis.

[0109] In another embodiment, in a case where the field device is a communication terminal of a station attendant, step S304 can include:

[0110] sending a safety state check message to the communication terminal, the safety state check message being used to instruct the station attendant to confirm the first state of the target device. For example, the communication terminal can be a walkie-talkie of the station attendant, and a dispatcher of the control center can talk to the station attendant near the target device through the walkie-talkie and instruct the station attendant to confirm the first state of the target device.

[0111] in a case where the control center determines that the first state of the target device is valid based on the monitoring device or the communication terminal of the station attendant described above, sending a first confirmation signal to the signal system.

[0112] Step S305, in a case where the signal system receives the first confirmation signal returned by the control center in response to the first request information, the signal system sends second request information to the control center, the second request information being used to instruct the control center to output the alarm prompt information again.

[0113] Step S306, the control system outputs the alarm prompt information again in response to the second request information sent by the signal system.

[0114] The method in which the signal system sends the second request information and the control center outputs the alarm prompt information again based on the second request information can refer to step S103, and will not be described in detail.

[0115] Step S307, based on the second confirmation result sent by the field device and representing that the first state of the target device is valid, sending a second confirmation signal to the signal system.

[0116] Step S308, the signal system determines that the first state of the target device is valid in the case of receiving the second confirmation signal returned by the control center in response to the second request information.

[0117] After the above 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 in the case of determining that the bypass or isolation state of the target device is valid, the signal system allows the target device to perform corresponding operations according to the bypass or isolation state.

[0118] Alternatively, after step S303, it can also include:

[0119] Step S309, the control center sends a first rejection signal to the signal system based on the third confirmation result sent by the field device indicating that the first state of the target device is invalid.

[0120] Step S310, the signal system determines that the first state of the target device is invalid in the case of receiving the first rejection signal returned by the control center.

[0121] Alternatively, after step S306, it can also include:

[0122] 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 indicating that the first state of the target device is invalid.

[0123] Step S312, the signal system determines that the first state of the target device is invalid in the case of receiving the second rejection signal returned by the control center.

[0124] That is, if the signal system receives the first rejection signal sent by the control center after sending the first request information, it means that the control center determines that the bypass or isolation state of the target device is invalid, and the first confirmation fails, so the signal system does not allow the bypass or isolation of the target device. If the signal system receives the second rejection signal sent by the control center after sending the second request information, it means that the control center determines that the bypass or isolation state of the target device is invalid in the secondary confirmation, and the secondary confirmation fails, so the signal system does not allow the bypass or isolation of the target device.

[0125] After step S310 or step S312, it can also include:

[0126] Step S313, after determining that the first state of the target device is invalid, performing a reset operation on the target device.

[0127] In addition, it is worth mentioning that the information transmitted between the above signal system and control center, and the control center and field equipment, can be ensured to be correct through a safety design of hardware redundancy comparison or a software heterogeneous coding of twice commands.

[0128] The hardware redundancy comparison is implemented through hardware, for example, two sets of hardware are used to execute a command, for example, a command is issued through human-computer interaction, and the command is processed through two CPUs. The command is output only when the processing results of the two CPUs are consistent. The software heterogeneous coding can be that two software codes are run on one hardware, for example, 2+2+2+2+2=10 can also be expressed as 2*5=10. The result is output only when the results of the two coding modes are the same. The above manners can improve the correctness of system transmission information.

[0129] In summary, the technical scheme provides a secondary confirmation mechanism for bypass and isolation in a rail transit system. The mechanism is implemented through secondary confirmation of a signal system and a control center. Compared with the related art that depends on manual confirmation of bypass and isolation states, the mechanism solves the problems of high failure rate of dependence on human operation and low system automation, and achieves the effects of safe protection against erroneous bypass or erroneous isolation, effective avoidance of safety risks after erroneous bypass or erroneous isolation, and reduction of the probability of personnel casualties.

[0130] Figure 4 is a flowchart of another safety detection method provided by the embodiment of the disclosure. The target equipment is taken as a platform door for example, and the safety detection method is introduced as shown in Figure 4 The method can include the following steps.

[0131] Step 1, the signal system acquires a door isolation state of the platform door.

[0132] Step 2, the signal system sends a first request for door isolation to the control center.

[0133] Step 3, the control center returns a first confirmation for the first request for isolation to the signal system.

[0134] Step 4, the signal system sends a second request for door isolation to the control center.

[0135] Step 5, the control center returns a second confirmation for the second request for door isolation to the signal system.

[0136] Step 6, the signal system determines that the door isolation state of the platform door is valid.

[0137] Step 7, the signal system allows the platform door to perform position isolation and allows the train to depart.
